Abstract

Kurniati, H. 2007. The herpetofauna of the gold mining project area in NorthSumatra: Species richness before exploitation activities. Zoo Indonesia 16 (1): 1-11. Field surveys of herpetofauna (amphibians & reptiles) were conducted in andaround the PT Newmont Horas Nauli Martabe Project Area for 23 days prior theexploration. Surveys involved visual observations, light attraction, hand collection andtrapping in all major amphibian and reptile habitats. A total of 42 species of amphibiansand 28 species of reptiles (nine snakes, 16 lizards & three turtles) were identified.Based on interviews with local people at Batang Toru Village, there was reliableobservation of two additional species of turtle (Cyclemys dentata & Manouria emys)and one species of snake (Python curtus). Of the more than 42 amphibians speciesand 28 reptile species observed, 12 represented unknown species (10 frogs & twoskinks); one frog species (Occidozyga laevis) might be a new record for Sumatra.Similarity index calculations indicated that herpetofauna diversity at the six sites wasdivided between forested and heavily disturbed habitat.

Abstract

Kurniati, H. 2007. Survey of Siamese crocodile (Crocodylus siamensis) habitat inthe Mahakam River, East Kalimantan. Zoo Indonesia 16 (2): 51-62. A survey wasundertaken to collect information on C. siamensis habitats and possible locationswhere C. siamensis occur in the lower Makaham River, East Kalimantan. Interviewswith local villagers confirmed that C. siamensis were still encountered, and thatbreeding still occurs. Specific wild habitats visited (Tanah Liat, Paya, Belibis, Amir &Mesangat Lakes) had changed greatly since 1995-1996, but weeds and sedimentationwere identified as impacting negatively on the habitats. Fishing pressure hadincreased in recent years, and young crocodiles were being caught during fishingactivities. Around 360 C. siamensis were currently in captivity at two crocodile farmsand in villages in the Mahakam River area. Hybridization with C. porosus had occurredon one of the farms.

Abstract

Kurniati, H. 2009. Morphological variations of Sumatran Toren frogs, Huiasumatrana (Yang, 1991) and H. modiglianii Doria, Salvidio and Tavan, 1999. ZooIndonesia 18(1):9-20. Based on an examination specimens of the Sumatran TorrentFrog, Huia sumatrana in Museum Zoologicum Bogoriense (MZB), Indonesia, severalindividuals were found to possess morphological characters similar to those of H.modiglianii, including the number of crossbars on the thigh, snout morphology, anddorsal and ventral pattern and coloration. A similar degree of morphological variationin H. sumatrana that close to H. modiglianii tentatively is named as H. cf sumatrana.

Abstract

Kurniati. H. 2006. The amphibians species in Gunung Halimun National Park,West Java. Zoo Indonesia Vol. 15 (2): 107-120. Five families of frog that exist inJava are represented in Gunung Halimun National Park: the Megophryidae, theBufonidae, the Microhylidae, the Ranidae and the Rhacophoridae. In the park, theBufonidae consists of two subfamilies, the Adenominae and the Bufoninae. TheMicrohylidae only has one subfamily, the Microhylinae, whereas the Ranidae consistsof two subfamilies, the Raninae and the Dicroglossinae. Frog fauna in GunungHalimun National Park is comparatively rich, including 25 species of the 33 species ofnative javan frogs. During herpetofauna survey in October 2001 to August 2002,twenty-five species of amphibian were found in Gunung Halimun National Park; theyconsist of two species of the Megophryidae, five species of the Bufonidae, one speciesTHE AMPHIBIANS SPECIES IN GUNUNG HALIMUN NATIONAL PARK, WEST JAVA,INDONESIA: Zoo Indonesia Vol. 15(2):107 – 120.108of the Microhylidae, twelve species of the Ranidae and five species of theRhacophoridae. Among 33 species of the native javan frogs, eight species areendemic to Java; however six species of the endemic species are inhabited in thepark; they are Leptophryne cruentata, Microhyla achatina, Huia masonii, Nyctyxalusmargaritifer, Philautus vittiger and Rhacophorus javanus.. In Gunung Halimun NationalPark, two major type macro habitats of frog are generally recognized. One major typemacro habitat is primary forest, where Leptobrachium hasseltii, Leptophryneborbonica, L. cruentata, Huia masonii, Rana hosii, Limnonectes microdiscus, N.margaritifer, P. aurifasciatus and P. vittiger are very restricted to this habitat. Anothertype is disturbed habitat, where human has intervened the habitat as secondary forest,degraded forest, cultivation or paddy field. More than half frogs species occur in thesehabitats.
