Preface
Preface ompared with previous times, the substantially improved possibilities for travelling have enabled an increasingly large number of people to reach other countries or even distant continents. Amongst these are a number who, be it at home or outdoors, spend their spare time wiLh intense studies of certain group of animals and/or plants. mall by comparison are the numbers of those who are able to study as a profession subjects such as behaviour, systematics and evolution, or the geographical distribution and eco logy of animal and plants. For many of these, and other nature lovers, journeys to poorly known zoogeographical zones will only be ensiblc if they are able to recognise at lea t a portion of the biological species living there. nabl ing this is one ofthc main goa ls of this book. Thc author have dealt in the main chapters of their treati e with all species of amphibian and rcptiles currently known to exist on Mount Kinabalu. Rising to 4,095 m Mount Kinabalu i the highest mountain between the Himalayas and the alpine mountain ranges of ew Guinea. It i situated in the north of the tropical island of Borneo, in the Malayan state of Sabah, and is marked by a variety of ecologica l conditions which, in turn, have created an extraordinary diversity of species. The visitor from central Europe will be su rprised to learn that the Kinabalu massif is home to 77 species of amphibians and J 12 species of reptiles, which equa ls the species diversity of tile entire European continent. The prescnt book is by no mean a compilation of existing litcrature publishcd by other author . Rather all authors except one have becn to the Kinabalu region themselves and have partly worked there for severa l months. They have therefore been able to combine the results of their own studies with an in-depth analysis of the literature to create a treati e original in character. The more than 30 pages of introductory chapters contain valuable information that may be interesting not only to the herpetologist. The attentive reader will be particularly pleased to find :
• The thorough analysis of the relevant primary literature with synonymy lists of scientific names,
•
something which was, unfortunately, insufficiently attended to in many books of a simi lar nature published during the past decades; A wealth of information , not yet otherw ise published, on the behaviour and eco logy of the individual pecies; Identification key for all herpetological taxa known to occur in the Kinabalu region; Excellent colour photographs of live representatives of almost all species; o cillograms and audiospcctrograms of the calls of many arnphibians .
In order to make the book acees ibJe to an international readership, it has not been published in the original language of the authors, but in Engli sh. "Amph ibians and Reptiles of Mount Kinabalu" places a tool in the hands of amateur re earchers as well as professional herpetologists which will not only eliminatc many identification problems in the field, but which can also be used for the identification of photographs and preserved material or that ofrecorded amphibian calls. I am convinced that, de pite the recent publication of a considerable number of checklists and some books more orientated towards the general public on the amphibians and rcptilcs of this region, this book will fwd ajustificd place in the libraries of many nature lovers. Those interested in the herpetofauna of Southcast Asia will receive it with particular appreciation.

How to use this book
This book is a comprehensive guide to the repti les and amphibians occurring on Mt. Kinabalu treating all species rccorded from the area and including all related taxa known to occur on Borneo. Tnclusion of all taxa serves the purpose to identiry also species, which are not yet recordcd from Mt. Kinabalu. EBENI-IARD & SJOOREN (1984) Ii led three species of snakes for Mt. Kinabalu, omitted here, viz.: Calamaria lowi BOULENOER, 1887, Ptyas carinatLls (GONTIIER, 1858) aJld Cerberus Iynchops (SCHNEIDER, 1799). Since no sources were provided for these records, the three species have been ignored in the present work. DAS & [ MAIL (2001) listed additional lizard species [or Mt. Kinabalu that have not been included here as the compilation is still under revision (pel's. corum. DAS). After a general introduction to the orders of amphibians (Anura, Gymnophiona) and reptiles (Squamata Testudines) occurring on Mt. Kinabalu supported by numerous illustrations, explanation of terms, formulae, and analyses individual families are discussed in detail. Taxa are introduced alphabetically irrespective of any taxonomical or phylogenetical relationship. With regard to illustrations preference was given to eolOlu' photographs that were taken on- ite in the area of Me Kinabalu, even if this meant to accept an inferior photographic quality. While the photographs primarily serve to illustratc the general appearance of a species, additional drawings are provided for specific features (e.g. oral fields in tadpoles, details of pholidosis in reptiles). Genera arc differentiated via dichotome keys based solely on morphological criteria. Additional data useful for unambiguous identification can be found in the species account. Discussion of an individual genu includes a table of distribution for all Bornean species and a key to these spec ies. AJ I taxa recorded from Mt. Kinabalu so far arc given in boldface. Species accounts are standardized providing the following information: thc valid scientific name, reference ofthe original description including the locus typicus (type locality; origin ofthe type specimen), a chresonymy list (as of end of 2000), a diagnosis, description of extcrnal features as well as ecological and ethological observations, and distribution . Scientific denomination follows trinomial classification. The basic unit of zoo logical classification is the species. Its scientific name is composed of two names (binomia1), that of a subspecies of three name (trinomial). Thc first name is the generic name, the second the species name, and the possible third the subspecies name. The taxonomic concept of subspecies is subject to controversial debates and we have thercfore linlited information on subspecies to unambiguous characters.
Synonymy/Chresonymy lists are limited to those references, which refer to an occurrence of the pecies on Mt. Kinabalu. Species munes and relevant synonymies are given with the respective authors' names, year of the publication, and page number(s); oompletc references can be found in the bibliography. Diagnosis is a compilation of generally valid data and serves to distinguish a taxon from other taxa on generic, specific or sub specific level. In case of a monotypical genus, the relevant taxon is differentiated from similar Bornean taxa. Description is based on own examinations and/or the standard publications for the region, e. g. DE RoolJ ( 1915 , 1917), INGER (1966), and MANTfl EY & GROSSMANN (1997). A descriptive summary of adult extemal features is accompanied by data on ontogenetic developmcnt or developmental stages where appropriate (c. g. amphibian larvae) . Measurements relate to standardized methods described in thc introductory chapters and are given in rnillimetrcs.

How to u e this book
Ecology/Ethology summarizes data on general behaviour, habitat preferences, vertical distribution. population density, feeding, predators and antipredator behaviour. It hould be noted that there is a painful lack of ecological and ethological information on many of the specie . Distribution compi les the entire geographical distribution of a species as well as its distribution on Borneo (for localities see map on page 11). Distribution maps are limited to those species for which a larger number of loeaJjties are known. Locality data relate to Our own studies, those taken from the literature are marked differently. Mt.lGnabalu contains listing of all known localities on Mt. Kinabalu (> 500 m a.s.l.) where a taxon has been recorded. Apart from a few unidentified placcs, all localities are shown on the maps on page 200, 203 and 204. Their spellings are very much inconsi tent in commonly u ed maps, and we largely follow the pellings u ed on a draft map kindly made avai lab le to us by BEAMAN. It is unfortunate that older record u ually do not include altitudinal information. 1n many ca e the altitude of the actual collecting site i likely to vary substantially from that of the stated locality as only thc nearest known location is given in publications. pecie detennination of specimen hou ed in lhe col/eclion ofKinabalu Park (HQ-Co/leclion) has been accepted without nlrther verification. Literature u ed in tbe introductory chapters and further reading are marked by an asterisk (*) in the bibliography section of this book. Errata: Fig. 94 on page 101 does not depict a member of the genus Lepto/a/ax but rather a ranid. The below given descriptions were received too late for inclusion in the text of this book.

Introduction Covering an area of739 204 square ki lometres, the biggest of the Sunda ls lands, Borneo lies in the central tropics. As far as size is concerned, it ranks tbird among the largest islands of the world, after Greenland and New Guinea. It has more than a thousand years of varied history, during which Indian , Chinese and - from the 16th century onwards - European tradesmen and colonial powers strived for territory, resources, and commodities. It was not before the end of World War IJ tllat the territories of Borneo became independent.
.. J11 1949, the formerly D utcb part of Borneo become Indonesian under the name of Kalimantan (535 834 km2 ) • .. In J963, tho formerly British northern part of Borneo joined the Malaysian Federaey; the provinces Sabah (73 620 kml) and Sarawak 123 985 km') were established. >I< In 1984, the forolerly British protectorate Brunei (5 765 km') gained independence. The economic dominance Brunei exerted in the region lead Europcan to using its name in gradual linguistic distortiolls (Brunei ~ Barllney~ BOnloo) to Signify the whole island. This name is still in corrunon uso nowadays. Gunung (= MOLlnt) Kinabalu, 4095 m, is the highest sUl11mjt of the entire Malay Archipe lago and is sitllated in the far north of Borneo, in the province of Sa bah. Apart from the summit of Makital Kal imantan (2987 m) it towers more than 1500 m above all the other peaks of the island. In former times indigenous people regarded the mOllntain as a place where they expected the soul of their deceased to be gathered in a village of the dead (Aki Nabalu), which was strictly off limits. From the mid-19th century onwards, the mowltain has been radiating a virtually magic attraction for botanists and zoologists due to its unrivalled diversity of species. ALmost instantly after having been incorporated into the Malaysian territory, it gruned the status of a protected Park, and even the capital ofSabab, tbe former Jessclton, derive its name from the great peak: Kota Kinabalu. For tourists it bas been an unrivalled attraction from the very beginning:
12
during the first decade after its first ascent, only 53 people climbed the mountain, whilst nowadays tcns of thousand annually follow their tracks. In pite of this mass rush, the mountain has not 10 t a bit of its aura. obody manages to elude the magic and majesty radiated by the granite giant emerging from the rain forest. The elevated language used in films and leaflets to entice the tourist to abah, the land of tbe " Sacred Mountain" , and to evoke the paradisaical wonders which await the visitor shows quite unmistakingly: the tonne!" rea lm of the dead has undergone a m tamorphosis to a national sanctuary. in biological terms, Mt. Kmabalu has remained what it Llsed to be in the last century: a great centre of biologicaJ diversity which is tillparalleled - not only in the Sunda area, but also worldwide.
Mount Kinabalu - the surrounding environment
Mount Kinabalu the surrounding environment In order to understand the distribution of specific species at any place n the earth, it is necessary to bave a clear idea about the fundamental abiotic and biotic conditiollS of the respective area under examination. The valid criteria are: * the geological and geomorphological condition s >I< the zoogeographical circumstances >I< the reccnt climatic conditions >I< the trucmre of the vegetation cover * the anthropogcncous impact on the environment The following chapters try to delineate an overview of thcse basic conditions for the area under inspection .
Topography, Geology, Geomorphology Mount Kinabalu, with 4095 m the highest mountain between the Himalayas and ew Guinea, is located at the northern tip of Borneo (5°57'-6° 18' , 11 6°28'-
I 16°45 'E). The central ~inabalu massif forms the shape of a horseshoe open to tbe nortb. Tbe uninterrupted rocky cJjJf facing south sends two ridges to tbe north separated by the J 500 m deep Low's Gully (the western ridge already descends rapidly after 2 kilometres, while the eastern one stretcbes far to tbe north, reaches once more all altitude of2576 m in the summit of Tambuyukon and descends in the range of Mt. Templar-Mandalon) and continues to the east down to Poring jointed into variolls lower ridge to the north and to the south. The massif is one ofthe most impoltant water catchments in abab and the source of many streams (e.g. Sg. Kinaram and 1\mran flow to the north, Wariu , Panataran, and Kadamaian to the west, Liwago, Mesiiau, Luidan, Langanan, Kinapassan, and Kapuakan to the east). Together with their in part temporary, tributaries and crossing through all altitudes they represent just about every type of habitat one may expect ill tropical montane running waters.

The area examined comprises in principle the entire mountain massif above 500 m above sea-level, but, for reasons of inaccessibility, i largely restricted to localities around Poring, Headquarters (inclusive of the Summit Trail), Mesilau, ayap, Kiau, and Bundu Tuhan. About 80% of the area lie within the boundaries of the Kinabalu Park. The crystalline basemcnt of northern Borneo is covered with a thick sequence of marine sediments which developed in the Tertiary pcriod. During the middle of the late Miocene period (somc 15 million years ago), these layers of shalc, siltstone, and sandstone were folded and uplifted to the mountain rangcs of the rockers and Trusmadi. During the Pliocene period (some 10 to 5 million years ago), a ubvolcanic intrus ion was exposed uplifting the overlying layers at the northern end of the rockers. The central swnmit plateau - today called Mount Kioabalu - consist of a granitic ceotre (hornblende adamellite), covering a surface of 150 km2, and an elevation of2000 and 3000 ill, surrounded with a ring of porphyritic and ultrabasic rocks (serpentine). These are followed

by tertiary edimcnls at lower elevations. On the so utheastcrn slopes (Pinosuk Plateau) up to 140 L11 thick Pleistocene layers of gravels are depo ited. During the last Pleistocene period, the swnmit region was covered by an icc-cap, about 5 km' in extent, reaching down to about 3000 m. Tllis glaciation has left distinctive landfonns not only in the summit area (polished and plucked su rfaces by the erosional action of the ice 00 thc plateau, nunataks, U- haped gullies, moraine material with subangular boulders at the end of such gullies and near Pakka Cave, cirques on the summ it), but the geomorphology of the lower lopes, situated in the periglacial zone, was tamped likewise (deposits by blockstream and mudflows on Pinosuk, forms of valleys and canyon ). The agents of the receol, chiefly chemical, weathering under tropical conditions (high temperatures and humidity) can be studied on the denuded summit area (exfoliation of slabs of rocks) and especially in regions deforested by man (partially up to 1800 m) with considerable soil erosion.
Mount Kinabalu - the surrounding environment
Zoogeography Together with the islands of Palawan, Sumatra, Java, and the Malay Peninsula, Borneo forms part of the so-called Sunda Plate, a southeastern spur of the Asian continental shelf. Between Borneo and mainland Southeast Asia, large parts of the Sunda Plate were exposed for much ofthe Tertiary. It was not before the Pliocene period that a shallow shelf sea separated the continent from the Sunda Islands. The Quaternary then was a period of repeated alternation of colder (glacial) and warmer (interglacial) spaces oftime. During the glacials a substantial portion of the water was bound terrestrially as glacial ice causing eustatic sea level changes worldwide (> 100 m max.). Under these conditions large areas of land of the Sunda Shelf were re-exposed and connected Borneo with the Asian continent. Distinct indications of this intermittent Quaternary falling-dry are given by submarine channels. They indicate the courses of former rivcrs at times when the platfonn was above sea level. Corresponding to the alternation of colder 311d wanner periods, these land connections were formed and broken several times. Fig. m The area of Sundaland (surrounded by a broken line) exposed at times of lowest sea Icvel (dark shade) during the last glacial with ancient river system (submarine channels).
Situated east of the unda platform, and reaching depths of several thousand metres in places, the Makassar Straits separates Borneo and Sulawesi. The latest connection between these two islands existed in the middle Eocene, more than 40 million years ago. During the Tertiary, arcs of volcanic islands were important as potential land bridges and island hopping routes for organisms to and from the Philippines, Borneo, and Sulawesi . The climate of the Sunda region during the glacials was probably 2-4°C cooler and more arid than it i today wIllie the interglacials had a wann and humid climate. These paleo-climatogeological conditions manifcst themselves in the existing zoogeographical situations. They help us to explain many disjunct plant and animal distribution patterns and the composition of species in the different geographical regions. II is significant that a major zoogeographical bOLmdary scparates Borneo and Sulawesi: the Wallace's Line. The islands west of this boundary - thus including Bomeo - form part of the Oriental Region, those to the east 'of it belong to the WalLacea, a transitional region between Orientalis and Australis. The relationsillp of the herpetofauna of Bomeo is signi ficantly closer to the Asian mainland and other Sunda islands than to Sulawesi despite its shorter geographical distance to the latter. This is proven by facts such as 70% of the snake and 43% of thc lizard species of Bomeo also occurring on the Malay Peninsula whereas only 25 and 19%, respectively, exist also east of the Wallace's Line. Nearly all non-endemic species of Bornean frogs (ca. 35%) are also found on thc mainland , but only 7% also on Sulawesi (of which 70% are fTOgS settling in cultivated areas which are very likcly to have been introduced by man). The large diversity of species of amphibians and repti les on Borneo in general and on Mt. Kinabalu in particular can be based for a large part on the following factors: • Most of the species of animals and plants show a tendency to increase their diversity the nearer to the equator they OCClLr. Borneo is situatcd in the central tropics within the species-rich Oriental Region . The amphibians and reptiles native to this region furthermore include numerous genera which are known for their rapid

speciation (e.g. Ansonia, Meristogenys, Phi/auILlS, Calamaria, Sphenomorphus). • Tbe repeated connection and separation of Borneo to, respectively from, the mainland during the Quaternary favoured an exchange of faunae in one situation and speciation processes in the other resulting in ca. 25% of the snakes, 45% of the lizards, and 67% of the frogs being endemic to the island. If the hypothe is presented by BRAl'
16
The geological age ofMt. Kinabalu is high enougb to enable many genera to have reached considerable degrees of differentiation through adaptive radiations manifesting themselves in the f01111 of localized endemites which bave adapted to certain ecological niches within certain altitudinal zones (e.g . Ansonia gllibei, Ansonia ju/iginea, Kalophrynus baluel1sis, Leptobrachium gUllungense, Phi/au/us saueri, Lepto/a/ax maurus, Calamaria schmid/i. etc.). Recognizing these species as localized endemites, however, requires a considerable amount or caution duc to the fact that our knowledge of the distribution of the animals is still very limited. As the average temperatures were several degrees lower than today during the Pleistocene, some oftbe forms classified as localized endemites may turn out to be in fact glacial relict which previously inhabited also lower e.levations, but were then forced to retrea1 to higher altitudes when the temperatures rose . Today they occur only in montane isolates scattered widely over the entire islands.

Notwithstanding this situation, extended dry periods are observed aperiodically with monthly precipitations of less than 30 mm. yclic changes in the atmospheric circulation (amplification of the southeast passats) in the form of the so-called EI ino Southcrn Oscillation often result in monthslong dry periods at irregular intervals (e .g. in 1977, 1979, 1982/83, 1992, 1997/98) exposing the ecosystem rain forest to sub tantia! stress and favouring catastrophic forest fires . For example, in 1972173 a prolonged drought distllrbed all woody plants of the upper montane forest in orne areas with shallow soils on Mt. Kinabalu.

The general climate may be altered significantly in places due to the individual topography. Outside prolonged rainy or dry period , a very characteristic daily weather pattern can be ob erved on Mt. Kinabalu : The first hours of daylight are marked by a clear or minorly overcast kyo Depending on the intensity of sunlight and wind, humidity drop from 90-95% to 40-70% out ide the fore t and in the crown of the trees, while it oscillates very little within the forest. Air saturatcd with moisture ascends the slopes of the mountain following its relief. As the temperature drop by an average of 0.55 to 0.65°C per 100 m incrcased altitude, the cooling watcr vapour condenses. The condensation level during the morning hours nonnally lies between 2000 and 3000 metres. This results in the formation of a ring of fog and cloud up to 3000 m altitude, covering the cntire mountain down to about [500 m during the course of the afiernoon. Heavy rain showers,

comparing an exposed ridge with a stream that flows in a protected gorge, even if both are situated at the same elevation and only a few hundred metres apart. It is signific31lt that it is exactly these gorges which represent the upper altitudinal distribution limit of many spccies offTOgS. The topograpbically induced network ofmicroclimatic niches experiences another fine-tuning of its differentiation by the vegetation cover. Below 3200 m there is only one natural type of plant [ormation on Mt. Kinabalu, i.c. forest. Depending On the heigbt of its crown canopy, significant aberrations of the individual climatic components may be observed within vertical distances of as little as 10 to 60 metres . The climate immediately above the leaf litter up to about 2 m is marked by being very constant as far as temperatures are concerned (daily variation usually less than SoC). Due to the ineffectivcness of air currents, the ground level is constantly covered by ai.r which is saturated with moisture; the relative humidity thus measu.res more than 95 % most of the day, with a minimum of 80-90% between 12.00 a.m. and 3.00 p.m . It is only when the dry winds accompanying the EI Nino weather phenomenon take cffect that the hu.rnidity may decrease to less than 60% for prolonged periods of time. The partly many-tiered erown canopy blocks out the sun so that merely I to 3% ofthe sunJight reach the forest floor although the intensity may vary
locally during the cou.rse of the day due to the shifting of sun-exposed patches. Entirely different climatic conditions are found at the level of tbe crowns si nce they are highly exposed to wind and insolation. The result is that individual climatic components are subject to substantial oscillations during the course ofa day, with temperatures varying by more th311 lOoC, and humidity by 50 to 60%. Between the floor and the crown level, the climatic components experience alterations of all kinds, so that it is just to speak of a vertical tiering of climates according to the tiering of the rain forest itself, in other words a "storey climate". Climatic peculiarities, lastly, result ii-om tcmporary gaps in the forest caused by wind storms and slides of the soil, and in the immediate vicinity ofstreruns. With amphibians and reptiles being poikilothermic aninlals. their activity is limited to a relatively narrow bandwidth of climatic preconditions. The knowledge oftbc many-faceted climatic conditions in their biotopes is therefore an essential tool for the understanding of their often insular niche segregation in a larger biosphere, their activity rhythms, and numerous other adaptive strategies. Figure VI demonstrates this principle clearly by showing calling activities offTOgS on the same site during various weather conditions, while fig. VIIT on page 26 shows the influence of the vertical distribution.

With the exception of the slopes ofLbe Kadamaian valley, the fianks ofMt. Kinabalu above 500 mused to be covered by virgin rain forest wltil as recently a the early 20th century. The e montane forests are home to the largest variety of plant species in the entire Malcsian region as the perma-l11oist Southeast Asian tropics are referred to in the cience of phytogeography. Besides hundreds of upper montane, subalpine and alpine endemisms (notably neoendemi ms in the vegetation facies on ultramafic ubstrate), it includes truly spectacular plants such as Ra.Ulesia which parasites on vines (Tetrastigma), sixteen species of carnivorous pitcher plants (Nepenth es), twenty-five specie of Rhododendron. and not less than 610 species of ferns, 350 of mosses, and 750 of orchids. BEAMA I\ & B F,AMAI\ (1990) estimated some 4000 species of va cular plants to occur on Mt. Kinabalu .

Every visitor to Lbe mountain cannot but note how the physiognomy of !.hc fore t change the higher he ascends. The mountain i virtually covered by stacked rings of vegetation zones with each having a specific composition of species. These altitudinal vegetation zone are the re ponse by the flora to the altitudinally changing climatic and edaphie conditions. otwithstanding this there is no strict demarcation between one zone and the subsequent one, but a gradual transition. While Indo-Malayan taxa dominate the lower elevations, the moderate altitudes are home to mainly East Asian ones, and AustralAntarctic floral elements reign above 2800 m.

Tropical lowland vegetation zone (to 900 m a.s.l.)
Climate: Levelled, moist-warm ; average annual temperature +26-27°C; precipitation throughout the year (2000-3000 mm). Soil: Yellow latosol with a thin layer of humus in the form of mould or mould-like compost as a result of a rapid rotting and mineralization of leaf litter. Vegetation: Multi-layered dipterocarp rain forest Upper storey: 30-50 m high tree giants (Shorea. DiplerOCatpus. Hopea, Vatica), moderately evident epiphytism. Middle storey: Dense, closed crown canopy 20 m above the ground (Annonaceae Meliaceae Myrtaeeae, Sapotaeeae), bamboo, lianas. Bottom storey: Lacunate, 8-10 m high underbrush; vines, bamboo and rattan thickets; plank roots; the floor is covered with a closed layer of lea flitter.
Water: Mountain streams with moderate to trong currents and occasional cascades; pronounced tidal changes relative to the weather. Structures: stream bed sediments dominated by coarse gravel, forming an extensive scattered pattern (hyporheic interstitial area); sand and gravel banks; rocks 3Jld fallen logs which protnlde above the water surface; pernlanently or temporarily connected rocky pools with fine sediment and deposits of leaf litter. Accounting for the strong CWTent and shade (usually only 2-5% of the sun light reach the water surface), no higher aquatic plants and fewalgae can develop. The water of these mountain streams is in general very rich in oxygen, poor in dissociating salts, alkalines, and acids as a result of the filter perfoLlnance of the fW1gai plexus which is associated with the root systems of tbe trees; pH 6 to 7; water temperatures rather stable (+ 17 to 20°e). Ephemeral rain pools or puddles and phytothelmes (water bodies fit for vegetation): limited to cavities in trunk or limbs oftrees, tree buttresses and )janas, as well as bamboo internodes. fUllnels in plank roots, and in the axjls ofleaves (e.g. Pandanus).

The diversity of faunal species of the Kinabalu massifis in no way inferior to that of its flora. It is a pure forestfauna of the East Oriental region with a high content of endemisms. On the other hand tropical rain forests are characterized by a quantitatively unproportional ratio between pJant and animal biornasses with an average of 1000 tons of plant mass to only 200 kilograms of animal mass. Tbe fact that the number of animal pecies is notwith tanding substantially higher than that of plants ' is explained by the large diversity of invertebrates which amount to little in weight. Most of the species are furthermore rather rare so that a high species diversity (richness) goes along with a low population density (evenness). The spatial niche segregation ofthe individual species - a large percentage of the latter is confined to the canopy - is so perfectly adapted to the habitat that every observer who enters a tropical rain forest for the first time (and who would not do so with the expectation to encounter an unlimited species richness?) will sureJy be disappointed and agree with WALI. ACE'S statement quoted above. The following is an inventory of what has been recorded to date from Mt. Kinabalu: 110' species of mammals, e.g. Orang Utan (Pongo pygmaeus), Red Leaf Monkey (Presbyfis I'lIbicunda), Grey Gibbon (Rylobates moloch), Slow Lori (Nyclicebus coueang), Tarsier (Tarsius bafleGnus), Flying Lemur (Cynocephalus variegatus), Pangolin (Mallis javanica), Porcupine (Trichys lascieLllata), Malay Bear (llelarefos malayanus), Leopard at (Felis bengalensis), Mou e Deer (Tragulus sp.), Barking Deer (Munliacli sp.), 22 species of bat (Chiroptera), 26 squirre ls ($c iuridae), 7 tree hrews (T\.Ipaiidae), and 7 civets (Vivcrridae). . 65% of the mammal species endemic to BOJ11eo occur on Mt.

therefore contributing more individuals than any other order of insects are termites (Jsoptera), ants and bees tHymenoptera). Most species occupy certain ecological niches defined as that part of the environment which a species actually exploits - and partly repre ent highly specialized morphological and ethological adaptation as a result of complex co-evolutionary developments of animals and plants, or of different animal species. They are fixed components of the rain forest and cannot survive without it. The highly advanced degree of differentiation of the adaptations also provides a clear indication of the old age of the Malayan rain forests as a stable ecoystem . As far as amphibians and reptiles are concerned, other animals are of vitaJ importance as predators and prey. Unfortunately that the prey spectra ofthe specie occurring on Mt. Kinabalu are as poorly known as their predators. The major part of the food of metamorphosed amphibians is composed of arthropods and their larvae, worms, and molluscs. Larger species, such as Limnonectes leporina. may also prey upon smaller vetiebrates, including member of their own species, and crabs. Most frogs are broad-spectmm carnivores (dietary generalist ); dietary pecialists are rare. M icrohylids, for example, feed mainly on ants and temlites. Predators of amphibians are particularly numerous among small mammals (e.g. civets, rats, otters) birds (owls, hawks, thrushes), and snakes (Amphiesmaflavifrons. Amphiesma sara·wacense. Dendrelaphis pictus, Rhabdophis chrysargos, Xenochrophis triangu/igerus) , but also include large spiders, centipedes, and crabs. The carnivorous larvae of dragonflies (Anisoptera) and aquatic beetles, hygrophilous snakes, and fish prey upon tadpoles living in the mountain streams and some may also ingest frog eggs. Nothing is known, on the other hand, about the predator of anuran larvae which live in stagnant pools . Potential dangers might come in the fonn of terrestrial crabs, larvae of small dragonflies, pond skaters (Baptista sp.), the larvae of mosquitos (Toxorhynchites sp.) and young, aquatic snakes. Due to their substantial sizes and physical powers, snakes (e.g. species of the genera, Python and Ptyas) play impor-

tant roles as predators among vertebrates. Many of the climbing species (e.g. Boiga, Dendrelaphis, Gonyosoma, Trimeresurus) prey mainly upon birds and plunder nests. Smaller arboreal (e.g. geckos, agamids, scincids), and fossorial species (e.g. Calamaria, Typhlops, Sphe/Jomo.rphus) feed mainly on arthropods and worm; the snail-eating snakes of the genera Pareas and internatus are largely specialized in preying upon molluscs and Gongylosoma upon spiders. Predators of repti les are predominantly found among predatory small mammals, wild boars, and birds (e.g. hawks, cockoos, thrushes, pittas). Lizards are the favourite food of many snakes, the smaJler ones being often captured by large hunting spiders. Besides the entirely unresearcbed parasites, the numerous predators arc a major controlling factor of the populations of amphibian and reptiles. Being carnivorous, amphibians and reptiles are secondary consumers of otber secondary and primary (vegetarians) conswners with amphibians usually occupying a midfield position in the food chains as second, third, and fourth level consumers. This is aJso true for many reptiles, although larger pecics may also be top predators "In many of food chains, within the food web.

Mount Kinabalu - the surrounding environment
Herpetofauna As of 2000, 77 species of amphibians and I 12 of reptiles are known from Mt. Kinabalu . Be ides some species settling in cultivated areas which occur in tbe marginal zone (e.g. Kaloula plilchra, Polypedates leucomystax. Rona et~vthraea, Raila nicobariensis, Fejervaty a limnocharis, Gehy ra Inutilata, Hemidactylus frenatus , Hemidactylus garnotii), the herpetofauna of the Kinabalu massif is composed mainly of forms particular to submontane and montane forests . These inhabit either trees at various storeys, the leaf-I ittered forest floor tbey may live subterreslrially, or have adapted to habitats dominated by mountain streams. Many species spend their entire life in the branchwork of trees and may only descend to. or near, the ground for a short period of time to reproduce; others are ground-dwellers, which occasionally can be fOlmd in the lower vegetation stratmn. While some species (e.g. Chaperinajusca, Rhacophorus nigropalmatus) undertake cxtensive journeys through the fore ts others inhabit rather small niches which they do not leave for years. The vertical distribution of some may stretch over more than -1300 m in altitude (e.g. Ansonia juliginea, Ansonia /ongidigita, Pelophryne misera, Cyrtodactylus ball/ens is, Phoxophrys cephalum. Amphiesma sarawacense), while others are only known from certain. well-delimited localities (e.g. An 'onia guibei. Leptola/ax maurus) . The adaptations to a life on the trees are particularly manifold. Arboreal reptiles have developed specific organs which aid climbing, such as scansory pads (Gekkonidae). strong, curved, and pointed claws (Gekkonidae, Agamidae), keels between the ventral and lateral scales ( erpentes: e. g. Dendre/aphis. Chrysopelea) . or prehensile tail s (Serpentes: Trimeresurus) . Frogs, on the other band, may have adhesive, glandular surfaces on their ventral sides and the pad of their finger and toe tips (Rhacophorids possess a cartilaginous joint between the subterminal and terminal joints which allows the pad to bc placed onto thc surfacc at a right angle). To be able to bridge larger distances between branches and trce trunks, frogs employ various leap-
32
ing techniques which are aided by particularly long hind limbs. Snakes havc solved this problem by employing a longitudinal muscle contraction which results in a stiffening of the body axis. Some species have acquired highly specialized adaptations, such as the ability to reduce the sinking speed of a frce fall by paragliding as a result of an active enlargement of the body urface thus enabling them to bridge larger distances in an oblique, controlled gliding flight. This may be achieved by a spreading of the ribs (flying snake: Chrysopelea), which may also be extremely enlarged and interconnected by skin membranes (patagia) (flying dragons: Draco), by employing appendicular lateral skin fringes like sails (flying geckos: Pfychozoon), or unproportionally large digital webbings (flying frogs : Rhacophorus). WALLACE (1869) was the first to describe and illustrate a "flying" frog (Rhacophorlls Iligropalmatlls) from Sarawak, a species also present on Mt. Kinabalu . Rain forests are marked by a distinct stratification of animal cOITIllHmities ill relation to its zonation. The various genera of scincid lizards (Scincidae) may serve as an illustration of this fact, with Sphenomorphus and Mabuya living mainly on the forest Door, Aptelygodon on tree trunks , and Lamprolepis in the canopy. In the case of agamid lizards, the circumference of the tree trunks leads to another type of segregation. with Draco distinctly favouring the mighty trunks of dipterocarps ,

Gonocephalus trunks with a smaller diameter (usually < 30 cm in diameter), and Phoxophrys and Aphaniotij,· slim trunks and bushes. Frogs of the genus Megophrys spend their lives on the ground, PhilaUius amoenus prefers levels between ]0 and 200 em above the ground in the mo sy forest • and Phi/autus bUllitus occurs at 3 metres plus on trees. Due to a lack of research we know next to nothing about the herpetofauna of the canopy. In contrast to the arboreal species, numerous ground-dwelling inhabitants cxhibit particular adaptations to a shady, moi t environment. Roots, fallen logs in all stages of rot, rock flakes , and an all-covering layer of leaf litter offer a highly differentiated range ofnicbes. Besides cacci1ians (i .e. Ichthyophiidae) and terrestrial frogs (Lepto brachium, Megophrys, Ka/ophrynus), the leaf lilter community includes numcrous fossoria! to semifossorial snakes (e.g. Bungarus, Caiamaria, Cylindrophis, Cal/iophis, Pseudorabdion, Oreocalamus, Typhlops), forest skinks (Sphenomorphlls). worm skinks (Brachymeles) , and glass lizards (Ophi·aurus). Blind snakes (Typhlopidae) and dwarf snakes (Ca/amaria) exhibit typical adaptations to a burrowing-boring way of life in the forest floor with the head being reinforced and compact with a reduced scutellation and reduced eyes (the blind snakes have eyes covered by scales), no distinct slimming of the neck, a short, spine- like, pointed tail suitable for anchoring, and a very smooth seutellation of the body. Mabuya and Sphenomorphus actively utilize shifting sun patches on the forest floor for their thermoregulation . Frogs of the genera Ansonia, Hllia, Limnonecles, Meristogenys, Rana, Staurois, and keeled skinks (Tropidophorus) strongly depend on mountain streams; some snakes (e.g. Amphiesmaflavifrons, X enochrophis trianguligerus) and the turtle Dogania subplana are hygrophilous. The larvae of 71 % of the anuran species of Mt. Kinabalu are known, 56% of which are inhabitants of mountain streams , the remainder develop in ponds and phytothelms. The species of the genus Phi/autus, which are known for their eggs to develop into froglets within a shell of jelly, deposit theiI eggs terrestrially at sufficiently moist sites (cushions of moss, rock crevices, beneath bark, and in dead pitchers of Nepenthes). Some ran ids (Limnonectes

finchi, L. /eporina, L. palavanensis) engage themse lves in parental care for tbeiI developing offspring. Tadpoles living in mountain treams are usually adapted to a life in certain ecological niches with some posse ing highly specialized adhesive organs to withstand strong currents. A remarkable feature in the appearances of amphibians and reptiles is the high content of shape and colour elements which correspond with plant structures (phytomimesis). 10 this respect some representatives of the families Megophryidae, Bufonidae, and Microhylidae imitate dead leaves (inclusive of the leaf's ribs and imperfections caused by phyllophagous insects), while lichen and bark structures are found in the body coloration of various frogs (Rhacophorus everetti, Ansonia hanitschi) and reptiles (Dra co, Phoxophrys, Ptychozoon), while again other resemble twigs and Iianas (Ahaelulla, Dendrelaphis. Pareas, Psammodynastes, Trimeresurus). By their shapes and colour patterns, frogs of the genera Ansonia, Meristogenys, and Staurois blend perfectly into their surroundings of rocks in the plashing zone of small waterfalls whieh are partly overgrown with algae. Some Amphibians and reptiles further enhance these cryptic effects by remaining motionlessly attached to the surface when they feel they might have been discovered. Many species (e .g. ofthe genera Phi/aulus, Rhacophon/s, Bronchocela, Phoxophrys, Draco) furthermore possess the ability to rapidly alter theiI colorations. This physiological colour change is hormone-driven and may be triggered by changes in

the surrounding temperatures, the intensity oflight, the level of humidity, but also by excitement. These colour changes do, however, not only serve the purpose of camouflage, but also play roles in commwucation and themloregulation. A perfect example for the function mentioned last i Phiiautlls aurantium which pos esse ' guanophores in its kin which retlect sun light. It enables the frog to avoid overheating by turning almost white in response to being exposed to sunlight while resting on a leaf during the day. Aposematic, brightly contrasting warning colours, as known from eotropical anurans (e.g. Atelopus. Dendrobates) are almost entirely absent in the species of Southeast Asia. The cbange of climate-induced ecological actualities, particularly between altitudes of 1200 and 1400 m, and between 1700 and 1900 m, respectively, corresponds not only with changes in the composition of the flora, but also with those of the fauna. umerous species of amphibians and reptiles reach their maximum, respectively minimum, vertical di stribution limits at these two altitudinal levels. The overlapping existence of highland and lowland forms in the area between 1200 and 1400 m causes the slight increase of number of species, though tendentious decreasing with increasing altitude. The oftenobserved congruences of these distributional relations in species of various genera underlines tbe distributional ecological importance of these boundaries. A drastic reduction of the specific diversity becomes evident at elevations above 1800 m, in the transitory zone to the mossy forests, so that the statement by I NGER (1978), "One of the disappointing things about Kinabalu's frog fauna is that it show so little altitudinal stratification.", clearly demonstrates the need for fundamental revisions. This tatement was very obviously based on an insufficiently large pool of information on the distribution of the amphibians in this area at that time. While our knowledge of the vertical distribution of reptiles on Mt. Kinabalu is grossly insufficient (only a handful, partly doubtful records exist for altogether five species from above 1800 m of which the records of Rhabdophis murudensis and Cyrtodactylus baluensis from 2500 m currently represent the maximum of the vertical distribution of reptiles from Borneo), at least some of the more vocal amphibians provide us with more acceptable in-
fomlation on their altitudinal distribution. Many genera (e.g. Leptolaiax, Leptobrachium, Megophrys, Kalophrynus, Ansonia, Philautus) appear on Mt. Kinabalu in the fonn of species groups, with the distribution ofthe indivi<;lual species being limited to certain elevations. It requires only an ascent up the mountain at night and the personal experience of just how sharply the individual vocalizations supersede one another and can be beard sympatrically only in narrow overlapping zones, to eliminate any doubts as to the existence of such abrupt vertical distribution boundaries. Figures VllI and IX (p. 26 and p. 27) shows clearly (with the exception of the area between 1200 and 1500 m) that the nwnber of species diminishes gradually with increasing altitude. Variou reasons are accountable for this. A particularly important factor - especially as far as reptiles are concerned is of course the climate whose upportive qualities for poikilothennic species of tropical areas deteriorate rapidly with increasing altiulde (lower temperatures, increasing precipitation, frequency of cloud cover). With increasing altitude the following changes are observed: • a reduction of the variety of ecological nichcs which is largest in the dipterocarp forests; • a reduction of the availability of food with the specific diversity and density of potential prey (mainly invertebrates) being subject to substantial limitation with increasing altitude; • a reduction of potential spawning sites. As a result of the topography, stagnant water bodies are absent and the streams above 2000 m usually have steep gradients. Their water levels often fluctuate between drying up completely and extreme high water. With the exception of Ansonia juliginea, whose larvae are unknown, none of those specie of frogs are found above 2200/2300 m which deposit their spawn in streams. For reasons already discu sse d in chapter "Zoogeography", the occurrence of endemic amphibians and reptiles on Mt. Kil1abalu correlates positively with the altitudinal level between 1400 and 1900 metres. It must be said, however, that their stati as endemites can at best be considered tentative as the totality of the species inhabiting the mountains of Borneo is not sufficiently known. In fact, many species previously considered endemites of

Mt. Kinabalu bave since also been recorded from otber mountains of the island, examp les being Leprobrachella balLiensis, Megophrys baluensis (?), Occidozyga halliensis, Sphenomofphorus kin abaluensis, Meristogenys kinabalue/1sis. Pelophryne misera, Cyrtodactylus baluensis, Oreocalamus hanilschi, elc. At present. 13% of the amphi bian species of Mt. Kinabalu are considered endemic to the mountain, i.e. Leptolalax a raya i. Leptolalax maw'us,
Leptobrachium gU/1ungense. Megophrys kobayashii, Ansonia j'uliginea, Ansonia guibei. Kalophrynus balLiensis, PhilaLilus amoenus, and Phi/autus saueri. AU of them have as to date only been found above 140011500 metres. 7% of thc reptiles of Mt KinabaJu arc currently regarded endemic, i.e. the lizards Hypsica/otes kinabaluensis,
Complicitus nigrigu/aris, Ptychozoon r/Jacophorus, Sphenomorphus tenuieulus, and the snakes, Calamaria schmidti, Hydrablabes pral!fi'onlalis, and TrimereSllnlS malcolmi. Since some of these species descend as far down as to Poring, their stati as endemites must be considered doubtful.

Davis B. Wake, 1994 Discovelies in the Niall Caves, Sarawak, prove that there has been human life on Borneo for at least 40000 years. The population density, however, was at such alow Level until the last century, that around 1900 more than 90% of the island were still covered with a complete and coherent primary forest.

Although SH ELFORD (1916) had already complained abollt an extensive destruct iOIl of the forests in the vicinity of settlements, the real decline of the rain forests did not start until the end the World War II . By 1957 the island had already lost 25 % of its forest. In 1953, Sabah, whcre every citizen could claim land as long as he wa willing to clear and cultivate it, was still covered with fore ts to an extent of 86%. [n 1983 there were only 63% left, in 1990 only 4 L%. The time bas passed in which one could still write like MJOBERG (1928): "The gigantic island of Borneo is clothed from head to foot, as it were, in green virgin forests ." How did this dramatieal decline come about? The most important reasons are: * Drastic increase of population. This leads to a continually growing need for new areas to settle in, whicb automatically implics infrastructural measures and woodland clearances. * Slash-and-burn as well as shifting cultivation by farmers; during some years with prolonged droughts in relation to EI Nino Southern Oscil-
lalion events between 1982 and 1987 as well as in 1997/98 trus kind of agriculturc caused fires of devastating extent; a total area of about 5-6 million ba. bad to be sacrificed to these flIes in the course of just the last ten years. * Highly develop-ed industrial nations (especially Japan) bought perrrussions for extensive logging for a period stretching far beyond the turn of the millennium. * Agro-industrially organised, large concerns promote the monocultural cultivation of oil palm trees and mbber plants on the cleared soil. These developments did not spare the forests ofMt. Kinabalu, as well. The surroundings of the mountain are inhabited by the Dusun people. Traditionally, they practise shifting cultivation (economy of changing land based on slash-and-bum cultivation: after a period of a 1-2 years' cultivation of a soil extremely lacking nutrients there follow fallow periods of various lengths), but restricted their economic actions to the glens of Kadmaian and the vicinity of Ranau, for the mountain itself was a

religious taboo. It was not before the middle of the 20th century, when the belief in the mountain gods had deteriorated to a mere myth, that extensive forested areas facing south were cleared - up to an altitude of L400 metres. Between Kundasang and Ranau extensive vegetable plantations were estabUsbed; in L958 a jeep track was built between the west coast and Ranau which was extended in 1972 to the so-called Transsabah Higbway connecting Kota Kinabalu and Sandakan. In 1964, 71 I kml of the Kinabalu massif were declared a protected Park under the administration of Sabab Parks; mountain lodges (in between 3200 and 3800 01) and a visitors ' centre (Headquarters, at L524 m) were established, followed by additional ones at Poring (500 m), close to "Hot Springs", in 1967, and in Mesilau (1860 m) in 1998. Eventually, 25.5 Ion 2 were sacrificed to enable the establishment of a copper mine in the vicinity of the Sungei Mamut source. In order to compensate for the loss and to silence critical voices, the park was enlarged to the north into the Templer region. This region covers an area of93 km2, but large parts of it consist of substituted forest on logged-over land. In 1983, one of the big fires raged in the eastern foothills, and it was only due to sheer coincidence that it did not reach tbe buttresses of the mountain itself. The omnipresent tampering with fire continues to be common practice around the mountain and is not liable to any restrictions. In 1984, the park boundaries were redefined and the protected area was reduced by 26 Ion 2 . Two areas of a particularly rich biodiversity were sacrificed up to an altitude of about 1800 m during these reductions, the rain forests of Bukit Hampuan and of the Pinosuk plain. Temperate fruit and flower farms, a dairy farm , and a golf course were established on the deforested aeras. Whell in 1989 first steps were taken to reintegrate Bukit Hampuan into the park, a fire destroyed the major part of the remaining forests. Within the boundaries of the park as well , there are deficiencies hard to understand, e.g. the introduction of a sewage into g . Silau Silau, water supply taken trom the upper parts of Sg. Silau Silau, Sg. Liwago and its tributaries. During persistent periods of drought this leads to a partial running dry of entire stretches of the rivers and brooks, the overdimensional new road at Mesilau with ditches
40
for rainwater (40 cm deep) running alongside without the slightest support for animals to crawl back up. These ditches fonndeadly pits for many of them (in March 1998 we fOUlld 34 withered Ansonia and Merislogenys and three Sphenomorphus within a stretch of about 100 metres). TravelUng from the Headquarters down to Ranau, respectively frOlD Sayap down the Wariu valley, is an experience of a devastatingly harsh scenic contrast. Mountain forests still untouched and pure a second ago abruptly give way to a chaotic view without any gradual transition ; the traveller is confronted with the entire range of unthought-of methods of overfelling and overexploitation: all over the plaxe randomly dispersed buts of corrugated iron, slopes eroded by mud avalanches, bare ridges, residues of secondary forests crumbled to charcoal , simmering rubbish dumps polluted brooks ~~th an increased water runoff and increased sedimentation rates, and the churned-up areas of copper mines. Ignorance, Lack of organisation, unlimited pursuit of profit, and the bunger for land amongst an incessantly growing population have contributed to the gradual shrinkage of the belt of a protecting buffer zone around the mountain . But: the time of patchwork tailoring is drawing to an end: it is not possible anymore to bum away forest in the south and add its territory in the north, for one is running out of wood resources there as well. In the meantime, the mountain's substance has become totally exposed ; its overboarding biological treasures are forced to recede to a highly fragile and extremely jeopardised insular territory.

Unti l thc beginning ofthc 19th century the Netherlands d id not have a fum grip 011 more than a couple of forts along thc coast. Vcntures into tbe interior of the islands, into the rcalm or cannibals, were looked upon as su icidaL Not before the time between 1820 and 1850 did the "Natuurkundige omissie" organize research excur ions, which invaded the central part of the island (e.g. by Borner, Gallion, Muller, Schwaner). The first zoologically important collection (or mammal and birds) was established on behalf ofthe Rijks Museum van atuurlijke Historie at Leiden. The herpctofauna did not attract any attention for quite a long time. The great snake atlas by SCHLEGEL (1837) does not mention more than one species as far as Borneo is concerned, Hydrophis pelamis. SClILEGEL (184854), GRAY (1845, 1859), and GONTHER (1859, 1864) then described for thc first time the amphibians and reptiles of Borneo stored ill museum collections at Leiden and London. Shorter herpetological works were published by BLEEKER between 1857 and 1860, and EOEUNG in 1865. fn 1885, FISCHER described a small collection made by Grabowsky, in 1892, Mo QUARD classified one by Chaper. The first check list of the amphibians and reptiles of Borneo (GONTH£R 1872) comprised already l57 species. Since by now more than a hundred years no significant progress has been accomplished as to the knowledge about the distribution and ecology of thc herpetofauna of Kalimantan, which suffcrs from a lack of research an)"vay. The scicntific research in the nowadays Malaysian part of Borneo has undergone a totally different development. Its beginning is inextricably intertwi.ned with the reign of the " White Radjas" of the Brooke dynasty, who resided at Kuching/ Sarawak. Scientifically interested Sir James Brooke was of paramount importance in this respect. He established his own collection, founded the Sarawak Museum at Kuching and roused interest in undertaking trips into the interior amongst naturalists and civil servants of his own administration by providing generous s upport. Without doubt, A.R. Wallace, who toured Sarawak in 1856, was the most well-known amongst them. During tbis time the first publication dealing with local herpetological data (MOTLEY & DILLWYN 1855) occurred.
Undcr the ru le of James Brooke, the "Sacred Mountain" became an object of scientific research. His co lonial minister Hugh Low reached the summit plateau for the first timc on the L1tJl of March 1851 , and he repeated the ascent together with Spencer t. John in 1858. The latter vividly depicts the expedition in his book, " Life in the Forests of the Far East (1862)". The trial s and tribulations, which lasted for weeks, did not mainly consist of the physical challenge of the ascent itself, but rather ofthe problems with establishing one el fat the base camp (the Dusun village Kiau) and with the recruitment of porters, who had to be convinced to invade the sacred aura of the mountain. The topograpby only aUows one route of ascent, wh ich was also taken by all subsequent expeditions. Still today the Summit Trail sticks to this route from 1800 m onwards, i.e. from Kiau (914 m) passing Lumu Lumu (I 676 m), Kamborangoh (2195 m)andPakka cave (3109 ill), up to the region of the summit. New route up Mount Kinabalu MesiJau trail promises more challenges Source: The tar, Friday, January 8, 1999 KOTA KINABALU
Trekkers intending to make their way up Mount Kinabalu, whether for the first or umpteenth lime, can now try out a new route which is also morc chal lenging than the existing trail whieh has been used more than 30 years. The new route, called the Mesilau Summit Trail, is located on the lesser-kno\vu eastern face of the mountain. rt starts at the recently-opened Mesilau Nature Resort ..... near a restaurant at the resort. The new 6 km route ends at the Layang Layang hut and hikers will have to trek for another 2 km before reaching Laban Rata ...... the new trail will trek through a montane forest and pass the Mesilau waterfall. ..... ''After 2 Ian at an altitude of 3000 to 4000 m, the trail goes downhill through a valJey ... , hikers can see a huge Agathis damara tree with its unique branches and roots," .. .. After passing through a number of streams and about 2.5 km into the journey, a 45 m-high waterfall can be seen. Then for another 2 km, the path snakes up a steep and narrow hill, the toughest part of the route .... after this section, tbe trail levels for 1.5 km and pitcher plants abound on both sides of the path .... the trai l then takes hikers tJlrough a rocky slope before they reach the Layang Layang hut at an altitude of 2702 m .

It has to be pointed out already at this stage that these altitudes, which were applied to later material, should be given a closer look before being taken over. This is especially vaJid as to "Kamborangoh, 2195 m". In pite of intensive research , many species (e.g. Ansonia longidigita. KalophfJ'nils pleUlvstigma, Cyrtodactylus baluensis. Sphenom01phus kinabaluensis) which were collected by Chasen and Pendlebury in 1929 and attributed by SMITH (1931) to thi s location could not be found at this altitude. Presumably they were collected somewhere alongside the track between Lumu Lumu and Kamborangoh . While the first attempts to climb the summit plateau are to be treated as rather sportive events without any scientific fruits worth mentioning, the ornithologist J. Whitehead did not only manage to climb the highest point ofthe plateau (Low's Peak, 1888) for the first lime, but also to earn scientific

merits; to Whitehead "belongs the credit of the first extensive exploration of the mountain and to him we owe our first real insight into the zoologica l treasures" (MO ULTON 1915). In 1893, WHlTEHEAD'S brilliant work "The Exploration of Kinabalu North Bomeo" was published. It was a decisive contribution to the formation of a new aura, the aura of an unfathomable biological trea sure. During the following decades Mt. Kinabalu became the place of pilgrimages for botani ts and zoologists alike, but never did a herpetologist occur amongst them. The herpetological section of Whitehead's collection was not edited by him himse lf but by B OULENGER (1887) and MocQuA RD (1890). Their list of species presents the first scientifically recorded amphibians and reptiles in the Kioabalu region. DUling the following 40 years civil servants of the Sarawak and Raffles Museums brought minor
Mount Kinabalu - the slUTounding environment
collections from Mt. Kinabalu every now and again, which were described by herpetologists who were not acquainted with the countIy by own experience; examples are the systematic descriptions of the collections of A.H. Everett by G.A. BOULENGER (1893, 1896), of R. Hanitsch by G.A. Bo LflNGER (1 99), of 1.A. Griswold by A . LOVERIDGE (\938) and of the biggest one, comprising 600 specimens, of EN . Chasen and H.M. Pendlebury by M.A. SMITH (1931). Due to the habit of considering the collector when creating the names of new species, we frequently encounter in them the names of scientists and of civil servants working as curators who dealt with fields of research totally different from herpetology (e.g. Trop;dophorus beccari;, Ovophis chasen;,
Pedostibes everelli. Oreocalamus hanitschi, Calamaria griswoldi, Philautus mjobergi, Meristogenys whiteheadi. etc.). Since the mid-fifties of the 20th century the research into the herpetofauna of Sarawak. and Sabah is very much intertwined with the personality ofR.F. Inger, now the Emeritus Curator of the Amphibians and Reptiles at the Museum of Natural History, Chicago. His classical work "The Systematics and Zoogeography of the Amphibia of Borneo (1966)" comprises the entire knowledge about the amphibians of the island available at that time. It also shows, however, how fragmentary the knowledge was back then. While already a high percentage of the descriptions of species is based on very old ma-
terial , data about ecology and ethology can be found only in fragments or are totally missing . This is the result of a research methodology predominant during more than a hundred years, which is characterized quite concisely by Shelford, as quoted in the heading of this chapter. As to the data concerning distribution, INGER himself remarked: "Analysis of the distribution of amphibians within Bomeo at this time is more likely to reflect the distribution of collectors than of frogs.". During the subsequent years INGER wrote (partly in co-operation with other authors like BACON, DRING, EMERSO , FROGN ER GRln , HAlLE, HOSMER, KING, LLOYD, TAN, VORIS, and WALKER), a number oftreatises on population dynamics, the bio logy of reproduction, and the settling in ecological n.iches by various species for the fust time. Apart from that he published many taxonomical papers describing numerous new species; he wrote particularly recommendable works about the systematics and ecology of tadpoles. Further descriptions of new amphibians were published by ISKANDAR (1978), DRING (1983a, L983b, 1984), MALKMus (1992b, 1996d), MATSUI (L986 1997), MALKMUS & RJEOE (1996a), MALKM US & MAT La (1997), and MANTHEY & STEIOF (1998). Due to these new insights and data the nwnber OfknOWll and described species has increased from 93 (L"IGER 1966) to L52 (Amua from 9\ to 146, lchthyophiidae from 2 to 6) amongst them Barbourula kalimallta-

Research on rePti le\~tilllingers on a. rather low level compared with that n amphibians. The latest total survey is provided by e work ofN. OEROOIJ (1915, 1917), which eocompas es the whole Indo-Malayan territory. MANTI·my & GROSSMANN ( 1997) published a volume, which comprises the whole variety of all known genera of the Southeast Asian herpetofawla; its impressive galJery ofbri II iant colour photographs adds to its cientific merits. Amongst the more recent revisions of the description of families, genera and species, INGER'S works (partly in co-operation with GREENBERG, HOS(l..fER, LEVITON, and MARx) occupy once again a dominant position, bcsides those of BACON (1967), HrKIOA (1982, 1990), GONTIlER & MANTHEY (1995), MANTHEY (1991) MANTHEY &
GROSSMANi\ (1997), MAI\THEY & DENZER (2000), MUSTERS (1983), 0tA & HIKJ[)A(1991) and WAI.LACH & GONTllER (1998) . HAILE (1958) and STUEBI"G (1991) published check lists of the snakes of Borneo, INGER & TAN (1996) did the same with regard to frogs, the lizards of Sa bah were listed by TAN (1993), the amphibians and reptiles of Brunci by DAS (1995), the amphibian and reptiles of Mt. Kinabalu by MANTHEY (1983) and MALKMU (l994b), the amphibians of Kinabalu by INGER, STUElliNG & T AK (1996) and INGER, Tt,"" & y ;\.\4BUN (2000). It is pleasant and satisfYing to note that recently five books about Bomcan amphibians and reptiles, written in a popular scientific vein, were published (JNGhR & TUEBING 1989, 1997, INGER & TA 1996, S, UEBING & INGER 1999, LIM & DAS 1999). Around the middle of the 20th century Mt. Kinabalu lost its formerly dominant position among the research territories of Borneo. This was not exclusively due to the f.:'Ict that one was tempted to believe that after a whole generation of scientists' intensity of work its zoology and vegetation were sufficiently explored; another important role played the fact tbat an exacerbated infrastructure and the use and deployment of helicopters made the remotest areas accessible (especially the central highland of Sarawak, the mountainous regions between Gunung

The expansion of the examination area brought about the insight that many species, which were believed to be endemic, turned out to inhabit other areas of the island as well (cf INGER 1978, lNGI:;.R & TUU3INCi 1992). This was, however, noth ing new to ornilhologi ts (M/OBERG 1928). Surprisingly, investigations undertaken since 1984 lead to the discovery of numerous new species of amphibians and reptiles, all of which still have to be treated as endemic species. This demonstrates that the investigation of the hcrpetofauna ofMt. Kinabalu is far from approaching a final conclusion . Figure XV demonstrate the historical development of coming to know the range of species at Mount Kinabalu . Scientists doing field work regularly brought back collected material from their travels. Most of the herpetological material is looked after in the following collections in museums throughout the world: The British Muscum of Natural History, London (BM); Field Museum of Natural History, Chicago (FMNH); Kyoto University Zoological Collection (KUZ); Museum of Comparative Zoology, CambridgefMass. (MCZ); Museum National d' Histoire Naturelle, Paris (MHNP); Naturhistorisches Museum Wien (NHMW); aturhistorisches MusemTI Basel • (NMB); Osaka Museum of Natural History, Osaka (OMNH); Sabah Parks-Field Museum, Headquarterl Kinabalu Park; Sarawak Muscum, Kuching (SMK); Forschungsinstitut Senckenberg, Frankfurt/ Main (SMF); Raffies MusemTI of Biodiversity Research, National University of Singapore (USDZ/ZRC); Sabah State Museum, Kota Kinabalu (SSM); Coli . Universiti Kebangsaan Malaysia, Sabah Univ. Campus (UKMS); United States national Museum, Smithsonian Inst. , Washington (USNM); Zoologiscbcs Forschungsinstitut und Museum A. Koenig, Bonn (ZFMK); Muscum fur aturkunde der HumboldtUniversitat zu Berlin (ZMB). Onc could still agree with Ingcr's comment on amphibians, dating from 1978, althougb a moderate modification secms recommendable: "Almost none of the information on natural histOlY comes from information madc at Kinabalu. There is much to be done."
This quotation does not on ly delineate a deficiency, but also functions as an appellation to draft a programme of future research activitics. It is also an appellation to get going. Especially three field s should form the centre of investigation :

Systematics: a whole variety of systematic problems arc to be tackled in this context. TI1is should not be attempted on a merely morphological basis, but also by including and considering ecological, ethological, and molecular data. Naturally, orne uncertaintie will not yield to clarification, as tbe products of a systematic approach are artificial and - like WILSON (1997) adequately pointed out: "scienoe to a bigh degree, but a bit of art as weU". Distribution: nearly all the data about places where animals were found is restricted to the close environment of Poring, the Headquarters, Mesilau, Sayap, Bundu Tuhan, and Kiau; apart from the summit trail there are no data conceming the areas above 2000 metres. All the data refer to the lower stratum of the forest (below 5 metres). Future investigations should include areas outside this very limited scope of observation, which barely covers approximately five percent of the total space. Almost nothing is known about the equitability (relative density and distribution) of the various species. atural History: we barely know anything about the natural history of most of the species (including the larvae). Tbcre is a lamentable lack of studies rescarch dealing with ecology and ethology (e.g. reproduction, acoustics, population dynamics, activity rhythms, settlement in niches, ctc.). As a crucial step forward in investigating the herpetofauna of Mt. Kinabalu, Sabal1 Parks havc initiated a program in 1991. Thcy work together with INGER, who monitors the population dynamics ofsclected species at three sites at different levels of elevation.
This book attempts to sum up the present state of knowledge about the amphibians and reptiles of Mount Kinabalu. It soon will become evident that the number of unsolved problems is vast. No doubt: "There is much to be done" !

Important traits for the identification of frogs and their larvae According to MAYR (1975) thc members of a species form a genetic and ccological unit and a reproductive community. The phcnotype, which presents itself in the form of never absolutely identical individua ls, is a summary of traits which reults from both endogenous (genotype) and exogenous (biotic and abiotic influences of the environment) factors. The selective pressures exerted by the latter may have favourable, eliminating, or varying effect on the development of individual traits. Such traits, or groups of traits show a more or less pronounced consistency specific to individual taxa and are therefore of importance for the classification of an animal. •
48
The species as a genetic unit: the ana lysis of the genotype is thc task of tbe laboratory biologist. As far as the frogs of Southeast Asia are concerned relevant work bas just begun. The spec ies as an ecological unit: it manifests itse lf in many-faceted interactions with the animated and unanimated environment, in particular by behavioural patterns typica l for the spec ies or genus, and by physiologica l adaptations. It requircs only a single apomorph ic feature to prevent populations from producing fertile progeny. Such differences may, for examp le, be variations in the aposematic behaviour, communjcation, activity rhythms , social structure, choice of ecological niche and calling sites, ctc . As far as Mt. Kinabalu is concerned, there are sta tionary bank-dwellers along the streams (e.g. species of the gencra Lepto/a/ax, Ansonia, Me rislogenys, Huia , Staurois, Rana ), ground-dwe ll ers of the forests which never (e.g. Pelophry ne, Kaloph rynus), or only for the purpose of reproduction visit streams (e.g. Leptobrachium , Megophrys ), or arborcal species which never (e .g. M etaphrynella, Nyctixa/us, Phi/aulus), or also on ly for the purpose of reproduction visit streams (e .g . Pedostib es, Po{y pedates , Rh acophorus).
•
The species as a reproductive community: behavioural pattems which can be linked to reproduction are to a large extent ritualized and particular specific to a species . This servcs to ensure a reproductive scparation among closely related, sympatric species. Ritualized behavioural parameters can be found in all interactions related to reproduction. Oviposition and volwne and appcarance of clutches may as well provide information as to which species or genus we are dealing with. Diumal, small frogs, for example, which show a "flagging" bebaviour with stretched-out hind limbs are certain to belong to the gcnus Staurois; if we encounter a free-hanging foam nest or one which floats on the water surface, we can be sure it were Polypedates or Rhacophorus which deposited tbemthere. The advertisement caUs often offer the key for distinguishing specics which cannot be separated, or are djfficult to diffcrentiate, by morphological traits (e.g. species of Phi/au Ius or Leptobrachium montanum vs. Lep lobrachium gunungense).
As valuable as biochemical and ethological data are for the identification of species, they usually require the emp loyment of costly instrumentation, large amounts of time, or depend on the coincidental concurrence of certain factors. The herpetologist in the field will therefore make use of the immediately availab lc traits of the pbenotype (external morphology) for the identification of a species in most of the cases. Many species of Bornean frogs can be identified without doubt on the basis of morphological traits only. It is on ly for highly variab le and phenotypically very similar forms (c.g. in genera suc h as Ansonia, Leptobrachium, Meristogenys, Microfly /a, Pe/ophryne, Philautus) that even the experienced systematist is faced with ditIiculties. As a consequence the identification keys for these genera are unsatisfactory. It is important for the user of this book to know the meaning of the tcrms used in the species accounts and how the metric details were taken, and the same appJie to the definition of the call characteristics. Only by this knowledge will it be possible to verify and compare them with own data.
Anura
Body shape and size of a frog u ually ugge t an affiliation to the family, and often point to a certain genu already. In order to ub equently determine the re pective genus and specie , a erie of traits are of great importance, such a the hape of the nout and pupil, the hapc, relative ize, and po ition of the tympanum, and certain kin tructures (skin surface smooth, granular, rippled, warty; size, hape, and arrangement of glandular raise , skin ridges and appendages; meristically highly variable groups of keratinized pikes on the lower jaw, chest, and finger ). Metric ratios and comparative data of two body dimension are often much more important than indications of linear size ( VL of adult specimens) as they are not only relevant for the identification of a pecie, but also for that of the repective sex. Here, we restrict ourselve largely to the following indices: • tibia lengthlsnout-vent-Iength (TU VL); • comparison head length head width; • distance of the anterior eye margin from nostril ;
• distance of the posterior eye margin to tympanum; • horizontal diameter of eye horizontal diameter of tympanum; • inter-ocular di tance - inter-narial distance; • length of finger and toe ; and the p ition of the tibio-tar al articulation when the hind leg is plied forward to the body, etc. The presence, re pectively absencc, of mandibular and vomerine teeth, presence or ab ence of nuptial pad in male , and the morphology of the tongue may al 0 be of importance. The arrangement and hape of the tubercles on the lower side of the hands and feet are often of great taxonomic relevance, and 0 are the hape of the finger and toe tips and the extent of the interdigital webbing. To de cribe the latter we will u e a formula in accordance with GLAW & VE~CE (1994): "Finger and toes are numbered. ach toe or finger is followed by the number of the phalanges, which are not webbed (in parenthese ). Only the visible phalanges, which are bordered by the subarticular tubercle , arc considered. 'i' mean inner side, 'e' means outer (exterior) ide of a finger or toe. 0, '4i(l)' mean 'at the inner side of the fourth toe there is one unwebbed phalange'."

The type of a water body and its altitudinal location can also assist in the attempt to detennine tadpoles as the larvac of the individual anuran species occupy in general very specific niches. Thc origin of a tadpole is therefore valuable information for the taxonomist.

The significance of larval morphology for the systematics can be demonstrated by a look at the Amolops-group where the genus Amolops was split up into the gcnera Amolops, Huia, and Meristogenys on the basis of morphological differences in their tadpoles (YANG 1991) and larval characters were crucial for detcrmining the evolutionary relationships among the taxa.

Larval feeding types As adaptations to their individual habitats and partly in order to be able to make use of certain food resources, anuran larvae have often developed substantial modifications to their body stmc!Ures (e.g. shape oftbe body, development ofeaudal musculature and tins, position and stmctures of the mouth area). In principle two categories are distinguished, i.e. endotrophie and exotrophic larvae. Endotrophic larvae gain nutrition for their development from parental sources (yolk): these froglets may either hatch from egg capsllies (Phitau Ius) or are free-swimming, nidicolous, nonfeeding tadpoles (Kalophrynus. Pelophryne). All the other species of Bornean genera have tadpoles of the exotrophic type. i.e. they are free-swimming, feeding larvae. (J 986) distinguished 5 larval feeding types: I) Bottom suspension feeders: in microhabitats away from streams and in stream areas with weak currents where fine sllspension and leaf dri fl cover the bottom. TadpoLes of this type (generalized pond-type) show no morphological specialization (e.g. Bufa [fig. 39J. Rana, Po/ypedales [fig. 40]). 2) Mid-water suspension feeders: in microhabit.ats away from streams (raiJl pools, pig wallows, potholes); larvae with large branchial baskets with dense ruffles, lacking beaks and denlicles (e.g. Chaperina [fig. 41], Microhyla [fig. 42]). 3) Obligate benthic feeders: in streams with moderate to strong currents; tadpoles feed on the epilithic film on rocks to which they cling. They have cup-like oral disks (e.g. Rhacophorus), sucker-type oral disks (e.g. Ansonia [fig. 43]), or abdominal suckers (e.g. Huia [fig. 44]. Meristogenys); larvae are rheophilous, with elongated, depressed bodies, long muscular tails, low fins, and small, non-bulging eyes.

Anura
4) Macrophagous feeders: larvae inhabit a wide range of microhabitats in streams; they are common in leaf dri fts and in interstices of gravel on the stream bottom (e.g. Leptobrachella, Leptobrachium [fig. 45] , Lepto/a/ax [fig. 46]); larvae with heavy, sbarp beaks. 5) Surface film feeders : larvae dwell in the entire range of stream microhabitats from riffles to potholes; they suspend particles of floating material from the surface film by means of their upturned funnel mouths (e.g. MegoplllYs [fig. 47]).

All these types of larvae are represented on Mt. Kinabalu although the bottom suspension feeders, which are typical elements of lowland waters, feature much less prominent than the rheophilous benthic feeder. Due to geomorphological and hydrological reasons, the nwnber of water bodies which would allow a successful development of amphibian larvae is very limited above 2000 m on Mt. Kinabalu; here, endotrophic fonns dominate (e.g. Philautus species). The realization of an identification key to the larvae is impossible at present since only 50-60% of the amphibians of Borneo are known by their tadpoles (comp. T}J GE R 1985 , 1992a, b, TNG ER & WAS ERSUG 1990). We must therefore be content with a key to the families here.

Bioacoustics On reaching maturity the males of most anuran species are able to vocalize. Most species develop - partly in both sexes - several types ofvocalizations (advertisement, release, distress calls, etc.). Among these, the advertisement calls of the males are of exceptional importance with regard to biological and systematic sciences.
I
Listeni.ng to nightly concerts of frog voices is certainly one ofthe most memorable experiences during a visit to a rainforest. The volume of thesc concerts is again and again surprising. It is mainly due to the resonant properties of the vocal sacs (sac-like extrusions of the bottom of the oral cavity) which vary in ize and position, but are gen-

Anura
sympatrically have developed more distinct call structures than those with an allopatric distribution (e.g. in species of the genera LepLObrachium and Philaurus). But it is not always the male which actively attempts to attract a sexual partner. For example, female Polypedale.l' leucomystax ready to mate advertise by producing single croaking sounds and a rhythmical dnunming with their toes (seismic communication) for minutes on end . On Mt. Kinabalu we are met with spatially finl1ly established calling colonies (e.g. of Megophrys baluensis, Metaphrynella sun dana, Staurois tuberilinguis. Ansonia longidigitata. Philawl/s aurantium) , those with calling densities which are unequally distributed over larger areas (e.g. Leptobracilium montanum, Kalophrynus ball/ellsis, Phi/autus bunittts and P picfus), and specics whieh produce singular calls at large intervals (e.g. Merisfogenys orphocnemis, Rhacophorus angulirostris). There are di- and nocturnal callers. Some voices give evidence of an adaptation to the acoustic background of their individual habitats. The dwellers of mountain streams for example produce sharp clicking, whip-cracking, or chirping signals in order to rise above the sound level of their biotope (rushing of water) and facilitate communication. The fact that advertisement calls are species-specific is of immense value for the field herpetologist since especially morphologically very similar species are typically distinctly differentiated with regard to their bioacollstics. It also helps to gain an overview of the local distribution patterns of the individual species. Until about 40 years ago, the description of advertisement calls was Limited to onomatopoetic descriptions such as a short, whip-cracking "cheep" -sound for Meristogenys or a burring "emrr..." for Phi/autus petersi, or by using musical note . Obviously thcse methods of illustration are very subjective and little informative. In order to record the physical call parameter (call length, fi'equency structure, intensity repetition rate of the impulses. length of intervals. etc.) objectively, the calls arc recorded on tape and, with the aid of computers, displayed in the form of sonagrams and oscillograms thus rendering them fit for comparisons. Sonagrams provide a basis to analyze sound levels, relative volumes, and the timing of acou tic signals.
58
When comparing analyses of voices it must be taken into consideration that factors such as humidity, temperature, light, and stimulation by the given acoustic environment, but also the volume produced by the individual, may have substantial effects on certain caJl parameters (particularly volume, frequency, speed of the pulse rate). To facilitate acoustic communication within the acoustically heavily polluted rain forest the individual species choose certain frequency bands. Just like radio stations use various carrier frequencies, frogs occupy various acoustic "chatmels", in other words acoustic niches within the overall backgrowld noise of their habitat.
Reproductive strategies In a worldwide survey, D UELLMAN & TRUEB (1986) distinguished altogetl1er 29 different reproductive modes which differ in the choice of oviposition sites and type of development of the larvae. 0 less than 10 of these modes have been recorded for frogs on Mt. Kinabalu:
I. Eggs aquatic A. Eggs deposited in water 01. Eggs and feeding tadpoles in lentic water (e.g. Chaperina. Kalollla, Occidozyga, Rana, Bufo) 02. Eggs and feeding tadpoles in lotic water (e.g. Lepfobrachella, Lepto/alax, Ansonia, Meristogenys, Huia, Staurois, Rana) 03. Eggs and feeding tadpole in water in tree holes or aerial plants (e.g. Metaphrynella) 04. Eggs and non-feeding tadpoles in waterfilled depressions (e.g. Kalophrynlls) 05. Eggs and non-feeding tadpoles in water in tree holes or aerial plants (e.g. KalopfllYnus, Pelophryne. Phi/autus) B. Eggs in foam nest 06. Foam nest on pond; feeding tadpoles in pond (e.g. Polyp edales, Rhacophorlls)
n. Eggs terrestrial or arboreal
C. ~ggs on ground or in burrows 07. Eggs hatch into feeding tadpoles that are carried to water by an adult (e.g. Limnonectes jinchi) 08 . Eggs batch into froglels (e.g. Phi/alilus)

10. Eggs hatch into froglets (e.g. Phi/aufus) E. Eggs in foam nest II. Nest arboreal; hatching tadpoles drop into ponds or streams (e.g. Po/ypedafes, Rhacophorus) ; foam nests were found not overbanging water, but the tadpoles would hatch during rain showers and then be washed to a water body.
Like tbe choice of oviposition, the details of the individual clutches (e.g. arrangement, number, size, and pigmentation of the eggs) are indi cative of genera and species. Unfortunately, only a relatively small perccntage of species are known by their clutches. Species dwelling the upper montane zone tend to produce smaller cl utches with larger eggs (e.g. Lepto/a/ax, Pe{opluyne, Philaulus). Whether all or at least some of the anurans at the various altitudinal levels are reproductive ly active throughout the year, is still llllknOwn . A far as Borneo is concerned, respective information is only availa ble for lowland rain forests (I NGER & GREENBERG 1963,lNGER & BA 'ON 1968).

Bufonidae
Bufonidae Bufonid are co mopolitan in temperate and tropical regions (except for Madagascar and the Au traloPapuan region) . Oriental bufonids have an arciferous pectoral girdle, the sacrum has di lated diapophy es, an omostemum is absent, a bony temum pre ent. There are 5-8 holochorda l, procoelou pre acral vertebrae. The maxillae and premaxillae are edentate. Most species have dry, thick, glandular skins, often with pustular wart . The pupil i horizontal. Mating takes place in an axillary amplexus. Most bufonid produce egg clusters in tring form (eggs normally pigmented) and deposit them in water. Their tadpoles are free-swimming, aquatic, have beaks and denticles: the piracle i inistral, the anal tube medial (except in PelopIIlYlle ). orne genera have torrent-adapted, oro-adhe ive tadpole with large, expanded oral disks and suckers (Ansonia) . 111e specie ofPelophty ne have non-feeding larvae which survive entirely on yolk. 80mean bufonids occur in various habitats, some are terrestrial (Bufo) , others arboreal (Pedosfibes) or both, living partly on the ground and partly on low vegetation (Ansonia, Pe/ophfJl/le); Pseudobufo is aquatic. Nearlyall pecie are distributed in primary and secondary forests, only a few appear in areas modified by man. On Mt. Kinabalu, bufonids can be found over a wide altitudinal range. Of the three frog pecies known to exceed an elevation of3000 m a.s.l., two arc bufonids (Ansolliafuliginea. Pelopllly ne misera) . The fami ly is represented on Borneo by 6 genera and 29 species, of which 5 genera and 12 species occur on Mt. Kinabalu.

Genus Ansonia
STOUCZKA,
1870
Members of thc genus Ansonia are known from southern India, Thailand , the Malay Peninsula, Borneo, and Mindanao (Philippines). Bornean species are mall to medium- ized. brown to black toads (SVL < 65 mm), with a dorsolaterally weakly flattened . elongate body with lender. long legs. Tympanw11 distinct (except in A. anofis, see p . to) ; in most specie rostrwn projects over the mouth ; nostrils above symphysis, large eyes (diameter ~ snout length), pupil horizontal. Tips of fingers and toes mostly rounded, some species with truncate disks. Finger lengths 3>4>2> 1, toe lengths 4>5>3>2> 1; fingers webbed at bases, webbing of toes varies with the spccies. Skin rough, usually warty ; parotoid glands absent. Adult males with subgular vocal sac (except in A. guibei), nuptial pads and mandibular spines present. Ova rather large and unpigmented. Tadpoles small (usually < 20 mm) and adapted to a benthic life in flowing water with a streamlined body (except in A. leptopus), and a cup-like, sucker-type oral disk; two upper and three lower rows of labial teeth, upper beak divided or absent, lower beak divided only in a few species (e.g. A. guibei). One species (Ansonia an otis) with an abdominal sucker. Body coloration usually black. These toads live in forest streams with strong currents (except A. /eptopus). Bornean species inhabit primary and old secondary forests in hilly to montane areas. They can be found on the forest
floor and on leaves in the lower stratum of vegetation. On Mt. Kinabalu, this genus has a distinct altitudinal stratification with A./uliginea reaching the maximum vertical distribution (3480 m) of all amphibians of the Sunda Islands . Some species are local endemics, restricted to very limited areas (A . Juligin ea, A. guibei). E leven species are known from Borneo, six of them occur on Mt. Kinabalu.
Remarks: There is some doubt about the occurrence of A. albomaculata and A. /eptopus on Mt. Kinabalu. INGER (1985) described larval Ansonia from Sg. Kipungit which he originally believed to beA. albomaculata. ln a later paper (L'IGER 1992b), however, he distanced himself from this view by leaving the specific identity of these larvae open and referring to them as Ansonia 'crucifonn" due to their dorsal pattem. On the other hand, A. albomaculata is listed again to occur on Sg. Kipungit in the check list of the amphibians ofMt. Kinabalu (INGER, STUE.BING & TAI\ 1996), while the works by INGER & TAN (1996a) and INGER & STUEBING(1997) do not mention it for Sabah, but only for Brunei, Sarawak, and Kalimantan . Another larva, which could as yet not be assigned to a species, was described by INGER {I 992b) from East Mesilau (1460 m) and from Sarawak. Like A. guibei, it has both jaws divided and is therefore referred to as Ansonia "beaks divided". In a new checklist of INGER et al. (2000) A. albomaculata, A. /eptopus and even A. minuta are mentioned for Kinabalu Park.

It can be found in both primary and secondary forests, plantations, and village clearings. B. divergells is mainly active at night, although it was also observed hunting during daylight hours. It feed on a wide variety of arthropods, favouring ants and termites. The males call at night, forming calling communities along the edges of spawning sites. Tadpoles occur in the shallow areas of stagnant or slowly flowing water in small streams (m: Ie, t). They are bottom suspension feeders (ING ER 1985, L986). Call: A series of short, raspy trills.

Ecology/Ethology Pelophryne misera is locally abundant in tbe montane forests of Mt. Kinabalu (1450 to 3100 m a.s.I.). While the toad was found active, foraging for food, and calling during the day at subalpine elevation it could never be discovered outside its hiding places (beneatb leaf litter, in rock crevices, holes in the ground, dead pitchers of Nepenthes) before the on et of dusk at altitudes below 2000 m. Its locomotion is a slow striding galt with the body rai cd high. Moving around like this, a foraging toad will plunge its head deeply into mosses, lichens, and leaf Iitter every now and again .

Megophryidae
Megopbryidae The Oriental megophryids are di tributed from Pakistan east to China, the unda Islands and the Philippines. The family is characteri ed by a arciferous pectoral girdle and a cartilaginous sternum and omostemum. The pre acral are not fu ed. The sacrum ha sub tantially expanded <,iiapophy es and is fused with the coccyx; the epicoracoids overlap at mjd-line. The parahyoid i absent, maxillary teeth are pre ent, vomerine teeth absent (except in the species of the genus MegophIJ's). The pupil is vertically elliptical , except of Opillyophryne. Mating take p lace in an inguinal amplexu . All Bornean species have aquatic larvae, most with beaks and labial teeth (except in the genera Leptobrachel/a and MegophfYS), and depre sed, spheroidal body shapes (except in the genus Megophrys). Megophrys have funnel-mouthed tadpoles. Bomean megophryids are terrestrial and live in leaf litter layer of primary rain forests, particularly in the vincinity of brooks. On Mt. Kinabalu they occur up to altitudes of 2200 m (Lepfobrachella baluensis. Leptobrachium gUflungense). Oil Borneo, the family is repre ented by 4 genera and 22 species, on Mt. Kinabalu by 4 genera and 13 specie .

Ecology/Ethology Leptobrachium montanum is one of the most common terrestrial frogs of Mt. Kinabalu (900-1750 In a.s.l.) and is encountered on tbe trails of the mountain forests almost regularly. It inhabits the leaf litter layer, even far away from running water.
96
A lthough some reports exist on its occasional diurnal ity (INGER L966, M ATS 1 1979) it is usually found outside its hiding places (beneath leaf litte r, roc ks, dead wood) on ly after th e onset of dusk, i.e . between 6.00 p.m. and 6.00 a.m. This is also the time when its call can be beard in the vicinity of streams, but also far away from these. Short duets an d vocal trios may arise, but these never escalate into choru ses like in L. gUn/lngense. L. man/anum is one of the few anuran species which continue calling to a considerable extent even during prolonged periods of drought. When disturbed, it either attempts to flee with short, low leaps, or closes its eyes and crouches to the ground with its limbs d rawn up to the body (ietisimulation) so that its phytolnimetic properties render it almost invisible. 1t s wim by using the hind limbs only while the arms are rigidly held forward at a right angle. Its cleansing behaviour includes numerous e lement of that of Kalophrynus baluensis (see the respective account). The ova of gravid females are cream-coloured with a sma ll area of dark pigment on the animal pole. The larvae of L. montanum are the most abundant tadpoles in the forest streams of their distribution

Width of head and body subequal; legs slender and relatively long. Vomerine teeth absent, tympanum visible. Tips of digits rounded, not swollen. Webbings between fingers absent, those between toe arc limited to the bases; large inner palmar tubercle not extending onto first metacarpal; inner metatarsal tubercle low, no outer one; subarticular tubercles on fingers and toes replaced by long, low, callous tis ue. Male withmedial subgular vocal sac, no nuptial pads. Females larger than males, with relatively horter tibiae and narrower head . The tadpoles of Lepta/a/ax are adapted to a life in streams, and have an elongated, slightly depre sed
shape. Small eyes, dorsolateral to dorsal , not visible from below; oral di k ventral and subtermina l, with cup-like expanded lips, at least one lip with short tooth rows; inframarginal ridges oflower lips lack mall denticles. Heavy beaks, serrated, and fully pigmented. Spiracle is sinistrally, mid-lateral. Tail lanceolate, 1.7 to 2.2 times the head-bodylength. Tail with strong muscle and low fins. Total length of larvae 60-65 mm. They inhabit clear treams in reaches with moderate to swift currents and occur yntopically with the larvae of Leptobrachella in the interstices of gravel bed . Adults can be found on the floors of primary and secondary forest where they prefer zones near streams with dense vegetation. The males call at night from branchcs of bushes flanking treams.

Ecology/Ethology Lepto/a/ax arayai is a very characteristic and common faunal element of the banks of streams crossing through montane oak-chestnut forests on Mt Kinabalu occurring at altitudes between 1400 and 1750 m a.s.1., occasionally up to 1900 m. It 1.00 1.20 1.40 1.60 1.80 sec finds shelter beneath leaf litter and bark, in holes in the ground, and cavities in dead wood. During prolonged periods of drought it often hides in the immediate vicinity of streams under rocks and wood on gravel banks, and leaves these only at the onset of dusk. Advertisement calls can be heard between 6.00 p.m. kHz 5.17 sec 10 and 5.30' a.m. (occasionally until 6.00 a.m.). The males call from the leaves and branches of shrubs and 5 bushes (20 to 200 em above the ground) on the banks of streams, very rarely also from boulders.

Genus Megophrys KUHL & VAN lliSSELT, 1822 TIle genus MegoplllYs is native to continental Asia, Sumatra, Borneo, Java, and pacts of the Philippines. The Bomean species are medium-sized to large frogs with relatively short, slender hind limbs and large, wide heads. Most species have characteristic dermal palpebral projec60ns (particularly above the eyes and on the snout) and a sharply curved ridge of skin between the eye and the ann. Tympamml is visible, but often indistinct. Adults possess a conical axillary gland at the insertion of tbe ann . Tips of fingers and toes rounded, outer palmar tubercel and subar6eular tubercles absent or indistinct; inner palmar tubercle oval, extending along first metacarpal. Webbing reduced to basal rudiments. Males possess vocal sacs and nuptial pads. The Larvae are slender and have funneJmouths; beaks soft, serrated, lacking labial teeth, but with many short, low ridges; oral disk terminal, lips expanded into a horizontal, dorsally-oriented funnel; spiracle sinistral; anal tube med.ial, fused to the ventral fin or not. The tadpoLes dwell streams in sections
105

Ecology/Etbology On Mt. Kinabalu, M. ba/uensis occurs in the vicinity of streams cutting through oak-chestnut and
lower mossy forests (1280-1950 m a.s.I.). It prefers the banks of small running waters, particularly fields of rock rubble which are densely overgrown by shrubs (Begonia, Gunnera, Impatiens). Here, the frogs live in very stationary calling communities. Five of those colonies could be traced always in the same spots on tributaries of Sg. Liwago between 1984 and 1998. Choruses can be heard between dawn and dusk with maximum intensities between 5.30 and 6.00 a.m. and 6.00 and 7.00 p.m., respectively. These are started by one male beginning to call, triggering others to respond, and so building up to a choms whlch then lasts for 30-100 seconds. The frogs call from rock crevices, cavities among roots, and holes ill the ground. They leave their shelters at night and forage on the forest floor, occasionally c1imbillg on low bushes up to about 30 cm above the ground. Their tadpoles dwell mountain brooks with weak current (m: Id, e). M. baluensis shows rituaused cleansing motions, otherwise known from species of the geoeraLeptobrachium and Kalophrynus. Captured specimens show a pUlsating trembling shortly before they attempt to flee.

Call: (+ 17 to 19°C) The calls are emitted in series of 3-8 loud, metallic, sharp, and hard strikes at intervals of 550-700 ms. They consist, especially in their second third, of distinctly di fferentiated pulses and last 90-100 ms; carrier frequency 2.8 kHz.
Distribution Until recently M. baluensis used to be listed for the fauna of Sarawak, Sabah (INGER 1966, INGER et a1. 1985, I NGER & STUEBING 1992) and Brunei (DAS 1995).The latest check list of the frogs of Borneo (I NGER & TAN 1996a), however, lists this species only for Sabah, and INGER & STUEDING ( 1997) consider it to be endemic for Mount Kinabalu, stating: .oM. baluensis is so far known only from Mount Kinabalu".

EcologyfEthology M. kobayashii dwells the layer of leaf litter on the floor of lower montane rain forests (1450-1675 m a.s.L.), preferring the neighbourhood of small streams, and hiding in holes in the ground, cavities among and in roots and among rocks . Its calling activity is limitcd to short periods of time in the early morning (6.00 to 6.30 a.m.) and in the late afternoon (6.00 to 6.30 p.m .), but calls can also be heard during rain showers (between 3.00 and 6.00 p.m.) when the daylight fades. It is usually one specimen which begins to call, triggering others to respond, and a full chorus is in place within 3-5 seconds. This species lives in pennancnt colonies. Larvae were found in small mountain brooks with weak current (m: Id,e). M. kobayashii appears to be rare.

Occasionally, a diumal specimen may be encountered. The ma les call from the vicinity of streams, particularly during the periods of dawn and dusk. They fonn very noisy choruses which, however, rarely last longer than 30 minutes. The white eggs (2 mm in diameter) are deposited on the underside of rocks and fallen 10 gs in those sections of streams where the current is moderate to weak (m: Ib-i ). The larvae prefer cal mer sections of forest streams, particularly accumulations of leaf litter along the edges of basins and on the bottom (m: I d, e, 1). They "suck up" floating particles from the water su rface by expanding their funnel-mouth. The latter does not serve as an adhesive organ (Bos HMA 1922, SCHMIDT 1976).

Tadpoles very similar to those of K. pulchra. E cology/Ethology K. baleata is a commensal species which finds refuges for the day under rocks, wood, and in the soil, but which has also been found in tree holes up to 2.5 m above the ground. Following heavy rainfalls, the males form noisy choruses along ponds, road ditches, and the margins of rice paddies. They inflate their bodies substantially during calling. The eggs are small and are deposited in clusters in puddles, road ditches, and small ponds (m: 2b). The food ofK. balaeta comprises small insects, pm1icularly ants.
Call: (+23 °C) A series of loud groaning honks in slow sequence. The notes are pulsed with a duration of280-300 ms, with a distinct decrease in intensity; dom inant frequency l-3 kHz.

Ecology/Ethology The bullfrog is a distinct commensal commonly encountered with in human settlements and anthropogenously disturbed habitats, in particular in land used for agriculture. It sUl"Vives periods of drougJ1t in underground hiding places which it excavates itself and which al so serve as shelters during the day. The males fonn choruses after rainfalls which may often include very many individuals (> 100) along temporalY stagnant water bodies. Here, the extremely inflated frogs can often be seen floating on the water surface . Females wh ich are attracted by the calling are immediately seized on arrival in an axillary amplexus. They dip their heads into the water at intervals, simu ltaneous ly raising the rear and releasing spawn . Any temporary pool may be uti lised for breeding purposes by this species (m : 2b, c) . The small eggs are laid in floating masses and develop at great speed. The frogs feed on small insects with a predilection for ants. Call: A loud groaning honk consisting of a single, partially puLsed note (0.56-0.60 s). Each note is composed of J 8-21 pulses at a rate of 32-35 pulses
Distribution The species is present throughout Southeast Asia. It has probably been introduced to the Sunda Islands and now occurs eastwards up to the Lesser Sunda Islands and Sulawesi. It is commonly presumed that it has reached Borneo only more recently. Mt. )(jnabalD: Only a single female specimen has become known from the Headquarters region , 1665 m (MATsUI 1979). This is likely to have been a translocated specimen as this spec ies is not normally a montane one and has never since been found on M.t. Kinabalu again.

The genus Microhyla is rustributed from China to India and Sri Lanka, in Southeast Asia eastwards up to Bali. All five of the Bornean species are small (except for M. berdmorei under 30 mm SVL), and have conical body shapes with a rounded snout and relatively long, strong hind limbs. They all share a distinct tendency for a reduction of the length of the first finger. Maxillary and vomerine teeth absent, tympanum usually not visib le. Males pos-

Ranidae
Ranidae Ranid frogs are almo t co mopolitan in distribution and ab ent onl y from southern outh America, the West Indie , most of the Aus tral ian continent, and many Oceanic i land . The Bornean representatives of this family exhibit all anatomical features typical for ranid frogs . They have a finni temal pectoral gird le, a sacrum with cylindrical diapophyses, and the omo ternum and sternum are 0 sified. Bony postzonal sternal elements are present, and so are eight holochordal , procoe lous presacral vertebrae and palatines. A parahyoid is absent, and the cricoid ring i complete. Maxillae and premaxillae are dcntate. The fingers are generally free of webbings , whi le we bbings b tween the toes are well-developed (except in the genus Toy /orona D U[lOI S, 1987). The pupil is horizontal. Mating takes place in an axillary amplexus . Ranids are extremely variablc with regard to size and habitus. They have conquered a multitude of ecological niches. The majority are ground dweller , but many can climb as well. Many pecies are close ly associated with water and never wander far from it. Other are, in contrast, typical in habitants of the forest floor, e.g. Limnolleclesfinchi and Rona [uc/t/osa. which may be encountered far away from any water body. Various species e.g. Rona sigllata
and lvferistogenys orphnocllemis. are known to leave the water bodies where they have completed their metamorpho is; they spend their early lives in the forest, only to return to aquatic habitats on reaching maturity. pawning usually takes place in the water, although there are exccptions i"n the fonn of species like Limnonectes finchi and L. pa/avallensis which depo it their eggs on land and later tran port the tadpoles to a water body. The larval development involves a tage of free-swimmi ng tadpoles (except in Tay /orana) . All tadpoles have beaks, denticles, and a sinistral spiracle. Most ranid larvae can be found in ponds, but some have adapted to streams (e.g. Merislogenys, Huia) . Bornean Ranidae are classified as belonging to the genera Fejervarya, Hoplobatrachus, Huia, Ingerana, Limnonecles, MeristogellYs, Occidozyga, Raila, and Slauro;s, and comprise altogether 38 specics at present. Representative of this fami ly are munerous up to an altitude of about 1500 m on Mt. Kinabalu, but only a few species arc present above thi elevation (e.g. Limllonectes kuhiii, MeristogellYs J..:illaba/uensis. Slaurojs tuberilingui ). The 22 species repre~ senting 8 genera which occur on Mt. Kinabalu account for some 60% of the ranid species of Borneo.

Genu Fejervarya
BOLKAY,
1915
A genu of relativ small to moderatly large robust bodied frogs . The kin texture is relatively mooth, but covered with longitudinal oriented skin glands in the form of folds . The tips of toe and finger are feature less, without any enlargements or di cs. Recently, Fejervarya was elevated from a subgenus of Lilllllonectes to genus rank by DUBOIS & OHLER (2000). They summed up some phenetic differences that exist between Fej ervary a and Limnollectes, such as the shape of the digits of adults.(OBLER & DUBOIS 1999), their types of male secondary characters (BOULENGER 1920) or the
K
differences in the mouthparts of their tadpole (FEI et al. 1991) . Additionally, D UBOIS & OHLER (2000) pointed out the existence of a dark ventro-lateral line from armpit to groin , a unique common derived charactcr only to be found in Fejervarya . More significantly even, the analyscs based on mtD A sequencing ofVEN ES (1999), MARMARYOU et al. (2000), BOSSUYT & MILI NKOVITCIl (2000) and EMERSO et a1. (2000) sugge t that Fejervarya is not the sister-group of Limnonectes (see also genus Limnonectes). Unfortunately, no up to date complete diagnosis of the genus Fejervarya was published so far. The genu Fejervarya comprises 14 species (D BOIS & O HLER 2000), two of which are pre ent on Borneo . Mt. Kinabalu is home to one of these species.

Taxonomic remark: The species originally included in the composite genus A molops were rearranged by Y ANG (1991) and are now allocated to the genera Amolops, Huia. and Meristogenys. The respective revision was based mainly on larval traits such a the number of continuous lower rows of denticles in the tadpo les of Amolops being three, whereas they count at least four, usually more, in Huia and Meris/ogenys. The upper beak is entire and Mshaped in the tadpoles of Huia, and divided in those of Meris/ogenys.

The distribution of the genus Hula covers the entire Sunda region and Yunnan (China). It includes more or less slender, long-legged frogs which are capable of very long leaps and perfectly adapted to a life in mountain stream habitats. The 1st finger is of equal length, or slightly longer, than the 2nd • The tips of the fingers and toes are dilated, the toes are connected by almost fully webbings. The length of the tibia is > 0.7 times the SVL. Like those of Meristogenys. the tadpoles of Huia are adapted to rapidly flowing stream by a large ventral sucker disk (gasteromyzophorous). The genus is represented on Borneo by only one species which oecurs nearly all over the is land (Sabah, Sarawak, and Ka limantan).

EcologylEthology Huia cavitympanum is a nocturnal terrestrial frog inhabiting the banks of fast-flowing streams in primary forests (250 to 900 m a.s.I.). Here, it is commonly found perched on rocks or hiding beneath them. Adults wander widely through the forests (INGE R & STU EBrNG 1997). The ma les call individually. Tadpoles live in the strongest currents of medium-sized streams, clinging to bedrock or boulders (m: la, b). Call: The call consists of a weak, high-pitched chirp.

brown with dark cross bars; venter cream-coloured; throat, more rarely also the chest, spotted or marbled with brown; lips striped; iris golden brown with fine black reticulation. Ecology/Ethology Jngerana baluensis prefers moderate altitudes of montane forests where it is primarily found along mountain streams. Here, the frogs can be discovered in rock crevices with spring water seepage on gravel banks, such as the 6-8 m wide Sg. Kadamaian. Their eggs are large (2 .2-2.5 rom in diameter) and unpigmented. The frogs are, however, occas ionally also found far away from water. They are excellent climbers on the vertical rock faces and capab le of long leaps. Distribution Endemic to Borneo, the frog has been recorded from Sa bah, Sarawak, and Brunei. Mt. Kinabalu: Poring, Sayap, Sg. Kadamaian above Kiau.
Genus Limnonectes
FITZINGER,
1843
The genus Limnonectes comprise mainly of nocturnal, moderately to very large telTestrial frogs that were previously ass igned to the genu Rana. The 2nd finger is never longer than the 1st . In contrast to the genus Rana. the finger tips are only slightly or not dilated. Limnonectes is further distinguished from Rana by the absence of marginal disk folds on the finger tips (except in the subgenus Elachyglossa ANDERSSON, 19l6) and the presence of well-developed odontonoid processes at the lower jaw of male specimens. They mostly lack advertisement cal ls and often also lack dorsolateral folds which are often distinctly developed in Rana. These frogs do not usually wander far from water, but there are exceptions, such as L. findli and L. paiavanensis. The genus Limnonectes is present on Borneo with l2 species and thus fon11S one of the most diverse

Taxonomic remark: The monophyly of the gcnus Limnonectes, as previously proposed by D UBOIS (1986 "1987", 1992). was often que tioned. Based on morphological and molecular data, EMER ON et al. (2000) showed that at lea t L. cQncrivora and L.

within a clutch. The males guard the clutch and transport the larvae to water bodies once they have reached stage 24 or 25 (following GaSNER 1960). Up to 30 tadpoles of 8-9 rom in length may be transported in one batch. A male was discovered near Poring carrying seven tadpoles to an ephemeral pond next to the road along the boundary of Kinabalu Park. This pond is fed only by a small temporary trick le of water, and its water was mu rky and practically stagnant, its banks werc muddy and overgrown to the waterline with low bushes and grasses. Neither the males nor the tadpo les show any morphological adaptations for this type of larval trans location. Free-swimming tadpoles were also found in rainwater puddles on the forest floor (m: 2b). Adults feed on small insects and spiders. Th.is species' altitudinal distribution ranges from 200 to 1150 m, but the population densities are higher at low elevations.

The distribution of the genus Meristogenys is limited to Borneo. Jt was not before 1991 that YANG split the composite genus Amolops into Amolops, Huia, and Meristogenys, mainly on the basis of larval differences (see also Genus Huia). The genus Meristogenys comprises small (especially small males in many species) to large, moderately slender, and long-limbed frogs. The head is longer than wide with a rounded snout. The eyes are large, and the tympanum is visible. The tibia length corresponds ""rith more than 0.7 times the SVL. The JSl flllger is generally longer than the 2 nd ; the tips of the fingers and toes are dilated, with the diameters of the finger tips being smaller than the diameter of the tympanum. The toes are fully webbed, and marginal disk folds, vomerine teeth,
and dorsolateral folds are all present. The skin is finely granular to smooth. The reproductive biology could be studied in detail in M . cf. orphnocnemis (MALKMUS 1998). Pairs migrate in amplexus to a mountain brook where the eggs are deposited under water on smooth rocks exposed to the current. They arrange themselves spontaneous ly after spawning to form a single-layered egg disk in which the eggs it side by side connected to one another by the jelly mass. After hatching the larvae form a school which remains stationary in an unusual density next to the now empty egg disk before they eventually disperse after 3-5 days. It is still unknown whether the reproductive biology of Meristogenys is different from that of Amolops or Huia. Like in the genus Huia, the tadpole possess a large , circular, ventral sucker as an adaptation to thei r Iife in streams with strong currents. The head is substantially broadened and flattened below.

They exhibit an M-shaped , keratinized upper beak which is costate distally, The V-shaped lower beak may sometimes also be divided. The muscular tail is 1-1.5 times as long as the body, The tadpoles possess small venom glands on the body and tail whose arrangements are indicative of the species. The larvae of the species Huia cavitympanwn differ from those of the species of MeristogellYs by having a larger number of rows of denticJes on the anterior labium and by the structure of the lower beak. In contrast to most of the other anuran gcnera the tadpoles of the species of Merislogenys are more easily distinguished than the adults whose body shapes and colour patterns arc very similar, As the morphological points of difference for the adults have often bee'n used in the literature in inaccurate or contradictory manners, we shall refrain from adding an identification key to the genus here , Of the 8 species in this genus, 4 occur on Mt.

Habitus of tadpoles oval and com pre sed dorsoventrally, with large ventral sucker; labial teeth rows formu la 5(4-5)6(1) at stage 38 to 5(4-5)/9(1) at stage 41; upper and lower beaks ctivided. The oral disk transfonns into a mouth during metamorphosis on ly after the resorption of thc larval tail. This
152
must be viewed as an aid for the larva to withstand the strong current of its habitat. Ecology/Ethology Meristogeny s orphnocnemis is both diurnal and nocturnal with adults inhabiting the banks offastflowing forest streams. The males can often be seen perched in loose groups at about knee-height on the vegetation-covered banks next to cascades. The heavier females are mostly found on the ground. Juveniles may also be encountered far away from water on the forest floor or in low vegetation. The males call individually or in loose groups while perched on slightly raised advertisement sites, particularly on the banks of rapids or smaH waterfalls . M. orphnocl1emis is the only species of Meristogenys whose reproductive biology is known (see also description of the genus above). Before and during spawning the sexua l dimorphism becomes evident with the large females carrying the much smaller males (53-55% of the females ' SVL) in amplexus to the spawning ites . Once they have arrived, the fema le spends some time in carefully selecting a suitable spot by probing the surface with her hind limbs and ventrum in back-and-forth motions. The adaptation to spawning in strong currents (m: l a, b, e, e) must be viewed as providjng the best possible protection for the larvae from potential predators (such as the larvae of dragonflies and beetles) and competitors for food, as these prefer the calmer sections of the streams. The about 800 eggs of a female's clutch are tightly arranged in an egg disk and held in place by jelly. They arc attached to a smooth rock surface exposed to a strong current. The jelly is transparent when produced, but becomes mi Iky within 1-1.5 hours after spawning, after the animal poles of the eggs have turned upwards, and then changes into a bright whitish blue. The tadpoles hatch after about 24 days, but stay in a dense school for another four days, slowly ctispersing thereafter. When disturbed, communal larvae immectiately sou ~ht the contact with their sib lings, while those older than four days reacted with taking to flight. The known altitudina l distribution ranges from 190 to 1500 m, after LAKIM et at. (1999) up to 1800 m.

Genus Occidozyga & VAN HASSELT, l 822
KUHL
The genu Occidozyga is distributed from Bangladesh, Myanmar and Thailand through the Sunda Island to the Philippines. It comprises small, dorsally flattened, and quite plwnp frogs with short, muscular hind linlbs, which are very well adapted to their environments with regard to their colour patterns. The tympanum is at least partly concealed by skin, the snout is flattened, and the eyes bulge substantially. The tips of the toes are slightly dilated to form narrow, roundish disks. While maxillar teeth are present, vomerine teeth are absent. The two Bornean representative of this genus live in or on small puddles, seepage springs, or in swampy area . Their tadpoles can be found in accWTIulations of water of all orts. The larvae are quite remarkab le as to their body shapes and behavioural patterns. They have very slender bod-

ies and tails with the latter being furnis hed onJy with narrow fi ns. The oral disk i situated terminally the upper lip is very narrow, the lower hor eshoe-shaped. There are no denticle , but the upper border of the djsk has a knob- li ke structure. The beaks are heavy and fineJy serrated. The spiracle is sinistral. The tadpoles of both Bomean species are carnivorous feeding on small in ect and their larvae. The genus Occidozyga is represented OD Borneo by two species which also occur on Mt. Kinabalu .

The almost cosmopolitan genus Rana ranks among the most diverse within the order anura. The frogs of this genu are heterogeneous morphologically as well as ecologically. They are in fact so heterogeneou that it is impossible to formulate a generalised description in the same manner as for the other genera. The tips of the fingers and toes are usually distinctly dilated, marginal disk folds are present. Dorsolateral folds are often present and distinct. On Borneo, tltis genus is represented mainly by noctumal terrestrial frogs (although Rana hosii is

often found climbing). Most species live constantly, or at least after having reached maturity, in the vicinity of water. The habitats are quite diverse with some species living on the bank of moderately large to large, others in or on narrow streams, others again in swamps or in flooded rice paddics. One species, R. {uctuosa, is in contrast a. strict dweller of forest floors which can also be encountered far away from water. Like the adults, the tadpoles of the individual species develop in a variety of types of water bodies and are adapted accord ingl y. The genu Rona is represented on Borneo by 9 species, 7 of which also occur on Mt. Kinabalu.

Ecology/Ethology
Raila chalconota is a noctumal inhabitant of the bank rcgions of rivulets cutting through primary and secondary forests, in swampy areas on the edge of cleared areas. The frogs are usually perched beneath or on dead wood or among banking vegetation up to 2 metres above the ground, but usually lower. The species is absent in deforested and other sun-exposed areas and thus differs distinctly from R. nicobariensis in its choice of habitat. Calling males and tadpoles were found between April and September. The brown-pigmented eggs are deposited in groups of 1000-3200 directly into the water. The larvae can be observed swimming slowly above the substnlte, predominantly leaf litter, in calm. water and forest ponds (m: 19, i). They are absent from water bodies with currents. Stomach analyses revealed algae and protists at equal shares, but also p lant particles and fungal hyphens . Adults feed on a variety of insects and spiders. lts vertical distribution ranges from 65 to 915 m, with a predilection for elevations below 300 m.
Call : The call consists of a staccato series of clicking notes. Males form large calling communities at the side pools of mediwn-sized streams and the edges of ponds.

Ecology/Ethology A shy, nocturnal, terrestrial commensal which also climbs in low vegetation. It actually avoids primary forests and owes its large distribution range to its ability to adapt to situations in and around human settlements. It is usually encountered iu the vicinity of water, very often in paddy fields. The males are often perched on grass or reeds, while the females are more often seen on the banks. The frogs reproduce throughout the year. The tadpo les are found only in stagnant water 'bodies (m: 2b). The diet of R. erythraea includes sma ll terrestrial invertebrates like small mil1ipede , crickets, and ants. This species prefers low elevations. CaJl: Although often found sitting close to cach other, the males do not form calling communities. The call is similar to that of R. nicobariensis, but the call duration is longer, the note length is shorter, and the number of notes per call and the note repetition rate is greater in R. elythraea.

Together with the trongly flattened ventral side this ventrolateral skin fold has the effect of a sucker when pressed to the smooth surface of a rock. EcologylEthology Rana hosii prefers the banks of clear, fast-flowing streams and rivers in primary and little-disturbed rain forests at low to medium altitudes. During the day, the males hide among rocks on the banks while the females spend the days 1-2 m up in the vegetation . Already SMITH (\930) remarked : "The habits of this species are those of a tree frog" , a hint for which are also the extremely widened finger tips. The species possesses a relatively potent skin poison (vernacular name " Poisonous rock frog") which is said to be strong enough to kill a cat. White to cream-co loured eggs (ca. 2.2 mm in diameter) without a halfmoon are deposited in lumps of ca. 500-2000 directly into the water (m: I b, c). The altitudinal di stribution stretches from near sea level to 1500 m . Call: The males call day and night in loose groups from raised sites and are often found in the immediate environs of water, in vegetation or climbing on rock cliffs.
The call consists of either one or two notes, witb the call of one note las,ting 70-80 ms, the one of two 160-170 ms. The frequency range varies and may even vary with the same ind ividu.al. Dominant frequency 3.3-4.5 kHz, decreasing towards the end of the caLI (+22°C). Distribution Malay Peninsula, Sumatra, Borneo, and Java. Mt. Kinabalu: Sayap, Sg. Kipwlgit, Sg. Mamut, Sg.

EcologylEthology The frogs are widely distributed, terrestrial commensals which are limited on Mt. Kinabalu to the margins ofthe national park, but are more commonly ncountered in the surroundillg villages. They are often fOWld sitting in drainages and other artificial water bodies and flooded meadows. They are both diurnal and nocturnal. Males are very common locally, but do not appear to form calling c.ommunities. The reproductive season lasts throughout the

Ta xonomic r emarks: Rana signata and Rana pieturata were for a long time cons idered conspecific, until INGER & TAN (1996a: 564) separated them on the basis of their colour patterns. In R. signata, the orange to red stripe runs without interruption from the eyelid over the back, whereas if such stripe is present in R. pleturata, it is always interrupted. The back itself is marked with many (R. pieturata) or a few to no (R. signata) spots in a colour matching the dorsolateral stripes. Another indication of tbe presence of two rather than one species is the inconsistency in the descriptions of the vocalizations of "R. signata" by GRANDlSON (1972), INGER & STUEBING(1992), SANCHEZ-HERRAlZ et al. (1995), and MANTHEY & GROSSMANN (1997). Since, however, no morphological or ecological differences have been confirmed up to now other than those of the colour pattem, both fonns are treated here jointly due to their great similarity.

Ecology/E thology Staurois latopalmatus is a diurnal and nocturnal ground dweller which is found along running waters, often on boulders in or on the banks of streams, but occasionally also in low vegetation. If disturbed, it will leap from rock to rock, or it may even leap into swift water and skip across the surface to another rock. AI night, juveniles are often encountered perched together in groups, whereas adults are mostly found singly. Foot flagging displays can only be observed between 6.30 and 8.00 a.m. duriog which time the males often congregate in group . Their calls can be heard throughout the night and the early morning bours (HARDING 1982, DAVI ON 1984). The vertical distribution of the species ranges from 150 to 1000 m a.s.1. Call: A short, rising trill.

Rhacophoridae
Rbacophoridae Rhacophorid frogs are distributed in tropical frica and Madagascar, but have their main centre in the Asian tropic and sUbtropics. Here, they range from lndja to Japan, inclurung the Greater unda Islands and the Philippines. Rhacophorid have a firmi temal pectoral girdle, sacrum with cylindrical diapophy es, omostemum and stemmn ossified, eight procoelous presacral vertebrae present. Maxillae and premaxillae dentate. Fingers and toes di lated into large rusks, short cartilaginous intercalary clement between penultimate and tenninal phalanges present; toes webbed over at least half thei r lengths. Some species of Rhacophof1ls with exten ive webbings on hands and feet enabling them to perform paragliding flights. Pupil horizontal (except in Nyctixalus). Mating takes place in ax,j llary amplexus.
The species of al l Bornean genera, save for Nyctixalus and Philalllus, produce roam nests in which the eggs deve lop to tadpolcs. The larvae are aquatic, with tenninal mouths with beaks and rows oflabial teeth ; tho e of Nyctixalus and Theloderma are non-feeding. Several lineages of Phi/auflls are known for their non-aquatic larvae - their eggs developing directly into frog lets. All Bomean specie arc tree frog , dwelling primary and secondary forests, some species appear to prefer habitat modified by human activity. Rhacophorids are very common on Mt. Kinabalu at all altitudinal levels up to 3000 m above sea level. The family i represented on Borneo by 5 genera with 35 species, on Mt. Kinabalu by 4 genera and 22 spec ies.

Ecology/Ethology Nyclixalus piCLUS inhabits the montane rain forests between 500-1750 m a.s.l. on Mt. Kinabalu . It is found off from streams in the lower stratum (shrub and bush level) up to 3 m above the ground, but also in the leaf litter layer. The species is nocturnal, leaving its shelters to forage with the onset of dusk. This spec ies is predominantly a sit-and-wait predator. Its diet comprises spiders, hairless caterpillars, and tbe larvae of beetles. Spawn was found in the form of clutches containing 7-15 eggs hanging on the wal ls of water-filled tree boles 1-1.6 m above the ground, and in large empty fruit casks 3-10 cm above the water level (m: 2d, g, h). Call: (+20.5°C) The note series starts off with 2-4 di linctiy pulsed notes (duration 34-45 ms; frequency 1.9 kHz; internote interval decreasing from 150 to 90 ms) which are followed b y 4 weakly pulsed notes (duration 10-13 m ;

Genus Philautus G1STEL, 1848 The species of this genus are distributed from India and Sri Lanka to China, the Greater Sunda Islands, and the Philippines. The genus Philautus comprises small to mediumsized, usually stout tree frog species, many of which are characterised by a confusing morphological variability. The resulting prob lems are even enhanced by the fact that many species are able to alter their colorations and patterns. The knowledge of the specific advertisement calls is therefore of fundamental importance for the field herpetologist. An attempt to establish an identification key to the species on the basis of morphological traits is for the same reason rendered entirely dissatisfactory. Under these circumstances wc are much rather ineI ined to fo II ow the proposal by DRThlG (1987) to allocate the Bornean fonlls to four species groups whicb are defined as follows: - aurifasciatus group: small or medium-sized species; vomerine teeth absent; nuptial pad small and smooth; ova unpigmented; calls generally pulsed, poorly tuned , with no frequency modulation. Content: P. amoenus. longicrus, l1yobergi. petersi. rejiJgii. saueri. umbra.
- hosii group: large species; vomerine teeth present; nuptial pad absent; ova with dark pigmentation ; caIls 110t pulsed, well tuned, with frequency modulation ; stream-associated species. Content: P hosii, ingeri. - teetus group: small species; vomerine teeth present or absent; nuptial pad large and spinulose; ova without pigmentation; call not yet described; lowland species. Content: P. rectus. vermiculatus group: moderately large to large species; vomerine teeth present or absent; nuptial pad absent; ova half-pigmented; call pulsed, poorly tuned, sometimes with frequency modulation. Content: P. acutus, aurantium. bunitus, disgregus, kerangae.
It must be stated though tbat this categorisation has meanwhile hlrned out to be in need offUitber revision. The species of the genus PhilautuJl are predominantly found in montane forests, between 700 and 3050 m on Mt. Kinabalu . The boundaries of the individual species ' altitudinal ranges are usually sbarply defined at high montane levels and do normally not include wider tTansitory zones. Most species inhabit the lower stratum (10-300 cm) which is where the clutches are also deposited in cushions of moss, rock crevices, leafaxils, and pitchers

of Nepenthes. Since it is known of P. kerangae, mjobergi, petersi, and SaUel'1 that their larval deve lopment up to metamorphosis is completed within the jelly sbell, it is to be presumed that this mode of development is equally applicable in all the other Bomean species of Philautus. Altogether 15 specie are known from Borneo, 8 of which from Mt. Kinabalu. Remarks: It is at present unclear if P. hosii occurs on Mt. Kinabalu. DRLNG(1987) re-identified a specimen described as " Rhacophorus hosiilBundu Tuhan" as being P. ingeri. Notwithstanding, P. hosii appears in the check Iist by INGER, STUEBlNG & TAN (1996) whereas P. ingeri does not.
Besides light brown specimens with almost 110 pattern save for a dark interorbital bar, there are pale brown ones with broad, dark dorsal stripes forming a sand-glass like marking. Others irregularly marbled with wide crossbars on light brown or bright scarlet. Some species with uniformly reddish brown or moss-green dorsal sides franled with black dorsolaterally and white flanks with fine blackish brown reticulation; lower side usually uniformly whitish grey to rich dark brown. All specimens, however, sbow an oblique white bar extending from posterior half of eye to upper lip; From top to base: Phi/aufus amoenus, between Pondok Ubah and Pondok Lowii, 2 100-2300 m.

iris yellowish brown to greenish with golden gleam and nelwork of tine black veins. Ecology/Ethology Philautus arnoenus is a typical inhabitant of the lower stratum of the mossy forest at elevations from 1800 to 2400 m, occasionally up to 2500 m a.s.1. Its calls can be heard already before the onset of dusk, increasing in intensity to climax between 6.00 and 8.00 p.m. The males cal l from leav.es and twigs on bushes and shrubs, rarely higher than 150 cm above the ground, occasionally al 0 from roots and tree stumps overgrown with mosses nearer to the
L80
ground. During prolonged periods of drought the frog is often found in cracks in the so il and rock crevices on the banks of streams, as we ll as in cavities among rock slopes. A clutch was discovered in Barnbusa gibbsiae forest at 2300 ill altitude . It comprised 15 eggs of 8-10 mm in diameter. They were hanging on the face of a rock fissure. Specimens kept in a lerrarium presented themselves as exceedingly voracious, trying to devour virtually everything that moved and did not exceed their own body sizes, in particular butterflies and hairless caterpillars, piders, flie s, roaches, but also
Rhacophoridae
wood li ce , ants and earthworms. Suita ble day shelters arc such as epiphytic cushions of moss, holes in branches and roots, rock crevices, empty pitchers of Nepenthes, and fruit husks. Call: (+12 .5°C) The hoarse, scraping note series bears some resemblance to the call of P bunitus and consists of notes arranged in groups of two or three (note duration II 0 ms; intemote interval 150 ms) which are emitted at intervals of 2-3 s. Each group of notes is preceded by a short grace note and is distinctly pulsed. The carrier frequency lies at l .8 kHz with harmonics at 5 kHz. Distribution Philautus amoenus is as yet known only from Mt. Kinabaln where it appears to be restricted to the high montane zone between Powerstation and Layang Layang and to the MesHau region .

toe webbing 1(1), 2(1 /0), 3(LJO), 4(1-0.5/1-0.5), 5(0-0.5); a low inner metatarsal tubercle, no outer one; dorsal and lateral skin smooth; tiny tubercles on legs and upper eyelid; chest and belly coarsely throat softly granular; supratympanic fold weak, but nevertheless distinct; males with a subgular vocal sac. Ground coloration light yellowish brown to reddish brown, flanks and sides oHead lighter; lower side uniformly whitish, partly tinged with rosy; occasionally small dark dots on throat and belly; inguinal region and inner sides of upper thighs intensely yellow; pitch black dots of various sizes on back, sides, and thighs, arranged in rows on back; iri reddish brown to yellowish brown with a golden shine and a network of very fine dark veins. The montane populations on Mt. Kinabalu were described as a separate subspecies , Phi/au/us aurantium gunungensis MALKMUS & RIEDE, 1996. They exhibit a tendency towards longer tibia, a relatively wider bead, and a longer inter-narial distance. Their advertisement calls differ distinctly from
those of the nominate form despite the similarities in structure. Their eggs are half-pigmented. Ecology/Ethology On Mount Kinabalu, this species inhabits the montane forests between 700 and L500 m a.s.l. The males form calling communities off from running waters. They call perched on the leaves of shrubs and bushes 50-200 cm above the grolmd. Calling activity begins with the onset of dusk, increases rapidly - particularly after rain showers - to a high intensity and continues throughout the night up to the dawn of the following morning. The calling communities are static to a remarkable extent: five colonies were observed in exactly the same places on the slopes of the Silau-Liwago valley between 1984 and 1998. This species is occasionally found during the day resting with the limbs drawn up against the body on leaves; such specimens are almost white with the dark dotted pattern suppressed (bird dropping mimesis).

Description
Rhacophoridae
Coloration and pattern extremely variable in specimens from Sarawak and Palawan; there are specimens with a barred dorsal pattern as well as con color ones, but none with a white streak below the eye or a dark network on a white ground. There is no description of specimens from Mt. Kinabalu.
Ecology/Ethology Almost nothing is known about the life history of this species other than it was found in primary forest between 900 and 3000 m altitude. It is active at night and arboreal, by day it rests under litter on the forest floor. Call: A harsh rattle, similar to the call of P mjobergi.
Distribution Philautus longicrus is known from the Philippines (1200-1550 m), Sarawak (900-1200 m), and Sabah (up to 3000 m) . Mt. Kinabalu: Layang Layang, Sg. Tibabar. INGER & STUEBING (1992) listed this species for an elevation of 3000 m (pakka). Bioacoustic studies, however, promote the idea that it shares the habitat on Mt. Kinabalu with P. amoenus at 1800-2400 m a.s.1.

EcologylEthology On Mt. Kinabalu , Phi/autus l1!jobergi is a typical faunal clement of the oak-chestnut forests at altitudes between 900 and 1700 m, occasionally up to 1800 I'n a.s .1. The males call mainly at night with maximum intensities between 6.30 and 8.00 p.m., and again between 4.30 and 5.30 a.m, but can occasionally also be heard during the day. They advertise from leaves and twigs of shmbs and bushes, but preferably from tborny rattan thickets, 20-250 em above the ground . On Mt. Mumd Mj6berg found them depositing their eggs in the pitchers of the Pitcher Plants (Nep enthes), no other water being available for the purpose (SMITH, 1925). A female captured on Sg. SilauSilau in August deposited shortly afterwards 7 large, unpigmented eggs (diameter of the jelly shell 6 mm) on a dead leaf in a terranum. Call: (+20°C) The advertisement call consists of a series of 4-8 metallic, sharp, pulsed notes (carrier frcquency 2.7-3.5 kHz; note duration 80-105 ms; inte1110tc interval 70-80 ms) which is followed by a pause of 0.8-1 s and a hOlt, marked final grace note. A note series inclusive of tbe grace note lasts 1.8-2.5 s and is repeated at irregular, often long intervals. Distribution Phi/auius mjobergi is probably the species of Phi/autus with the
Rhacophoridae
widest range on Borneo. Mt. Kinabalu : Common in the entire Headquarters region (1400-1800 m) with additional records from Mesilau Cave, Marci Parei, and Sayap.

Taxonomic remarks: The original type locality is a composite based on specimens from Mt. Dulit, Mt. Penrissen, and Mt. Kinabalu (pakka). However,
the Kinabalu syntype is "an unidentifiable juvenile" (DRING 1987). Diagnosis A stout species of the aurifasciatus group with a very characteristi~, single-pulse-train call; vomerine teeth absent; lingual papilla present or absent; dorsal surface tu ercular; fema le with a tubercle on tip of snout. Description Males up to 27 mm, fema les up to 37 rom; TLlSVL 0.5-0.66. DRING (1987) noted marked differences in the morphological ratios of specimens from various geographica l regions. Similar di ffe rences are also found on a smaller scale in specimens from various elevations from Mt. Kinabalu (MALKMUS & RIEDE 1996a). Head broader than long; snout ell iptical in outline, rounded in proftle; canthus rostralis rounded, lores

Dor urn brown to grey, pattern high ly variable; flanks lighter; groin and lower flanks flecked with reddi sh brown; underside whitish to grey; iris brown to golden, with a central horizontal dark bar. Ecology/Ethology On Mt. Kinabalu, P. petersi occurs in submontane and montane forests between 800 and 1700 m a.s.l. The males call from shrub thickets, 30-300 em above the ground, often adjacent to rivulets. The
190
Rhacophoridae
day is spent hidden beneath dead leaves and bark. The female 's keratinized tubercle on the tip of the snout is possibly used for the excavation of nests, perhaps in epiphytic mosses. Amplexi were observed in the month of August. A clutch of this species was found on a dead leaf in the leaf litter layer at Sayap. It contained up to 25 unpigmented eggs. Call: (+ 19°C) The call is a 1.2- 1.5 s long train of 16-56 rough pulses (pulse duration 20-25 ms; pulse rate from 27 (in specimens from Sayap) to 46 per second; dominant frequency 1.6-2.2 kHz; weak harmonics between 5 and 7 kHz; no frequency modulation. The calls are emitted at intervals of several minutes.

The record by SMITH (I 931 a) "Kamborangah, 2200 m", very likely refers to P amoenus. That the " unidentifiable juvenile" (DRING 1987) from Pakka Cave at 3000 m altitude in the series of syntypes represents P petersi, can be dismissed with certainty.

EcologylEthology Calls of P. saueri can be heard at altitudes between 2200 and 3050 m a.s.l., very rarely though below 2400 m. In contrast to all other species of Phi/autus occurring on Mt. Kinabalu, the males of this species call also during daylight hours, even in bright sunshine. Their diumality must certainly be regarded as an adaptation to the fact that the temperatures at these altitudes not rarely drop to just 5°C at night. This point of view is supported by the observation that calls could still be recorded at 10.00 p.m. in the less elevated mossy forest (below 2600 m). The males call out oflow, very dense bush vegetation. Four pitchers of Nepenthes villosa were discovered in the Leplospermuln-DaClydillln forest near Pakka, in August 1994, which each contained 9-17 gelati-
111 .
Rhacophoridae
nous capsules of 11-15 mm in diameter of p. saueri. 20-30% of these capsules did neither contain eggs nor embryos, but were m 'cly filled with liqu id. The other she lls held larvae at various stages of development. All these pitcher were dead and leaking, although their well-shaded location and contact to the ground secured the necessary moisture for the development of the larvae. It remains unclear, though, whether the contents of the individual pitchers were the product of one or several pairs of these frogs . Call: (+ 15°C)Anote series consists of 2-4(5) pulsed notes (note duration 30-40 ms; pulse rate .150 per second) at intervals of70-100 ms at a carrie r frequency of 1.9-2.6 kHz. paced by a pause of often several seconds, a drawnout "gweeh" sound (duration 90-120 ms) may follow, which may also be emitted alone . The structure of the note series exhibits certain simi larities w ith that of P. mjobergi.

Genus Polypedates
TSCHUDJ,
11 I 1838
The genus Po/ypedates is distributed from China and Japan, through tropical Southeast Asia, up to the Philippines, Borneo, and Java. Although CHANNING (1289) demonstrated in a phylogenetic study that Po/yp edates is a genus separate from Rhacophorus. its validity has remained a subject of debate. In contrast to Rhacophorus, a portion of the scalp is fused to the skull in Po/ypedates (except in P. colletti). and the ringfold 00 the lower side of the digital disks typical for Rhacophorus is missing in Polypedates. While Rhacophorus possess webbings between the fingers, such are absent in Polyp edates. The Borneao pecies are relatively large tree frogs with compressed bodies and long limbs. Vomerine teeth present, tympanum visible, pupil horizontaL Fingers and toes with enlarged pads at their tips, toes webbed over half to almost full length. Males with subgular vocal sac and nuptial pads.

male assumes tbe active advertising by ascending to a branch, drumming against it for minutes and occasionally emitting a croak. It does usually not take long for some males to arrive. Once a pair is united in an amplexus, it chooses a site for building a nest in the branchwork of a bush 10-70 em above a water surface or along the bank of pools on the ground (earth, rocks). The female then expel s from its cloaca a liquid produced by foam glands which it whips to a primary foam with its hind limbs. The subsequent thrust contains the eggs (l50-900) whjch are mixed with the male 's sperm and the foam. The female does most of the nest bwlding and is supported by tbe male only occasionally (KABIS H et al. 1994).

Reptiles are marked b a skin covcr,,'<.1 With scale. and ru ually have a t;reeping mode oflocum li n.

Squamata
(scaly reptiles)
In contra t to crocodiles. squamat .. all l1ave -n. transversally arran 'ed anal slit , and no teeth are viSible when the mOlflh is c1l ed, Males po 'css a pair of copulation organ. (pene ) of which but one i.' employed for the actual mating. The skin i' covered by n prote tive layer of horny scales which doe, not grow with the animal and ha t b shed trom time to time. The underlying new scale cover then' slightly lar er than the previous on . The hypodermi. (lower layer of skin) c ntains pigment cells whieh detcrmin the colouration and colour pattern of a reptile depending on the type and arrangement of these cells. Thi. rdcT c mpriscs two suborders, named Sauna (IInrds) and erpentes ~~~~~i (snakes), re pc tively. The latter have evolved from the Iimrds and Ulcrefore --~..,., repr 'cntamuch unger stage ofevolution. Lizard ' arc usually, but not genemlly, characterized by our limbs and movable eyelids. ' nake.• on the other hand. do neither have limbs. nor movable eyelids, nor ear openings. Certain fo orial groups bnng about complex problem as to their proper allocation to one group or another. The members ofthe snake family Typhlopidae (blind nakes) fOT example exhibit kull structure which are very similar to those of lizards. while the lizard family Dibamidae (blind skink ), who 'e members do not po e s limbs (male with rudiments) or tympani, hare many traits with the nakes.
Oizards) Lizards have conquered almost aU types of habitat . high up on trees and have devel ped the ability t controlled gliding flight, other dwell on or even in the Several of them are e cellcnt swimmers, and a f~w even avoid the ocean . Lizard" feed mainly on live . some spec ies al so prey upon molluscs , worm , vertebrates, crustaceans, and carrion, or have pecializ<,'(i on a vegetarian die t. Our knowledge a b lit how lizards live in the wild j . till relatively limited . ervations are u ually superficial and restricted to brief moment before a lizard tak to flight and disappear into the layer of leaf litter (like many kinks for example), r da hes up a tree trunk with tremendous peed and thus withdraw ' frOm the uriou eye of an obscrv 'r. th r li7Nd . rely on the camouflage effects ftheir colours and colour pattern which blend in with their surroundings and may not give themselve ' away by mo ements for hOllIS on end. 1"0 locate them in tbe semishade of a forest is extremely dillicult and very much dependent on incidental di. eove ry. Very few lizards are !rue to a locality for longer periods of time 0 thata purposedriven earch is rendered extremely difficult ifnol impo 'ibl . ome 110 sp ics oflizards are repee eated on Borneo whi h are systemati . Ily grouped in eight families and thirty- e n genera. Five 0 thes families and twenty-five genera have been recorded from ML Kinabalu (sec Fig. XU). Usin identification key (page 223), they can eil: ily be al their proper families. onsiderably more dlfficult. is the correct allocallon of represcntatives of the Sc inc idae . where generic trait'> ar not a lwa ys externally, and Gekkonidae, wher indicative traits can sometimes o nly be evaluated with U1e aid of a magnifying g la:.s. This is even more tru when it tht: iOl.'J1tifieation of the individual ·pceic:.;. The latter require. the use of a binocular microscope which U",li"""~ the counting of se'lles etc., but a layman may still be faced w ith ins um10untable problems. As la r a. the agamid arc concerned, Ihe generi c identificatIon i somewhat easier beca use it can be based on relatively welldiscemi hle ex ternal tmils. When it come. to spec ies level , however, anulher ki nd of compl ication may make itsel f felt as fe males often exh ihlt all appearance which is enllrely dissimilar to that o f the males of Ihe same species. A ' the pigmcnt cells e mbedded in the hypodcnn is can alter the colouration and the di tribut ion ofcolollrs to a sometimes sub lantial extent by cha nges ill cell ize and arrangement , colour and patte rn traits have only a limited suitability for idenlifi ati on purposes.

Gckkonidae
Gekkonidae Geckos have a cosmopo litan di stribution inhabiting all tem perate and tropical regions. Often they arc the first reptiles to invade newly formed islands (e.g. from volcanic eruptions). They are sma ll to modera tely large (total length up to about 400 mm) . mainl y crepuscular and nocturnal lizards. typica ll y wi th a granular skin stnleture. sua ll y they possess \'ertical-oval pupil s as well as adhes ive lamellae underneath their digit · (subdigita l lamellae). The armngement and shape of the 'e lamellae are impOl1ant fea tures for the identi tication of . evera l genera. Adhesive lamt:llae enable gcekos to climb on seeming ly smooth. vertical. urfaces. Geckos arc known for a highly evolved autotomy and the abi lity to regenerate lost tai ls. Regenerates arc however different in skin. tructure and shape. Geckos inhabiti ng Borneo u 'ually posses (origina l) tai ls which arc longer than the snout-vent- length . In co nt rast to most other gro ups of li;tards. many gekkon id lizards arc ab le to produce clearly audible sounds which onen arc indicative of a spec ies. They feed on a large variety of invertebrates and severa l species exploi t the abundance of insect. att racted at night by electric light. Many gcckos adapted to manmade altera ti ons of' nature and liw in and around human habitations. All . pecie in the range reproduce by laying eggs which Illay be attached to a surf~lce . Produc tion of several fertilized dutches alier a single Illating process is (Amphigonia retardata) is not uncommon among geckos. Borneo is home to I I genera compri sing 29 geckonid species with R genera and I () species occurring on Ml. Kinabaili .

have colonized a m~lltit.ude of ccologicnl niches. Many :;pecies inhabit shrubbery and ~s !10m are terrestriat a .f:,'Te;tt 'lUmber of them ~\re ra1her ineon piCU01IS and have foss rial habits; some liv in .fte hwai:er throl1~Ybout 1heir Jives, a number of others ven inhabit the oceans . .Many naKesJdT eHent climb -rs lind ase ne equally specialized ~11 snail or slugs, earthworm ', frogs, lizard.• insects, eVeo tennite , amplUbiU!l or (eptilc egg. , or bats. Observing these animals in Jlaturo ol\ell proves rather difticult. As a consequence of lheir position bigh up in the food chain. they have to be mueh more infTequenlthan Iheil' natural prey. In addition to this they spend most oftheil' time concealed and leave their hiding places usually only lor purposes 'ul:h as foraging or mating. Most species are crepuscular and l:<Jn therefore only be observed during the early hours of dawn lind dusk. Due to their noiseless type of 10c0l11otion and Ihe inability to voca lize Ihey hardly give away their presence. Most encounters are therefore pure coinl:idences. This is particularly true in th e case or fo ssorial species which arc mostl y found only by lurning over rocks and rorting logs. SOllle species hunt by ambushlllg prey aud oilen remain Illotion le 's for day '. This habit is usually aided by perlcd eamounage. Whilo most snakes arc oviparous, some give birth to hve young. In a few cases, an active incubation of the eggs can be observed , with th' female roi ling around her 'llIt ch and optimizing the incubal iontell1p 'rature by muscular l:onll1ll:tions. As far as Uomeo is concerned, the 135 species reeordcd from there arc grouped in 10 fall1ili 's and (i I genera. Of these, 7 1 ~lIl1 I1i es in 40 genera and 67 SpeCH.!S occur on MI. /(jnabalu (camp. Fig. XIII , p. 36). Using the identification key, individual s pec ill1 e n ~ ca n easil y be as. igned to a f ~lIllll y. AII()cating a certain speetnlen o rrolubrid ~ n ake 10 the eOITeel genu~, however. proves far more di!1ieult as this is the famil y \\ hleh accommodates the greatesl numher or spe..: ies. In Ihis case it IS usually nccessal)' to evaluate :l l:omblnalion o r w lour and lepidolic trai ts. The sexes hardl y differ with regard to their appea rances, hul IlI ll o~'e ncti c Iransformation ' are a common phenomenon meaning that Juve nilc~ bear diOcrcnl co lour patterns than the adults.
