Karakteristik Penangkapan Ular di Wilayah Sumatera Utara

Beberapa jenis ular eksport asal Indonesia yang mendapat perhatian dunia adalah Python reticulatus (sanca sawah), dan kelompok “sanca gendang†yaitu: P. curtus (sanca ekor pendek) dan P. brongersmai (sanca darah). Ketiganya masuk dalam daftar Apendik II CITES. Salah satu permasalahan dalam memahami kondisi populasi di alam pada kelompok reptil ini adalah luasnya habitat dan letak geografis, selain dari sifat satwa itu sendiri yang tidak memungkinkan dilakukan sensus secara terstruktur dalam satu satuan waktu yang pendek. Untuk itu perlu dilakukan suatu kajian tidak langsung yang dapat menjadi indikator penting mengenai kondisinya di alam. Tujuan penelitian ini adalah mengetahui karakteristik dan produksi dari kegiatan pengumpulan sanca sawah dan gendang di daerah Sumatera Utara. Penelitian dilakukan pada bulan September 2008 dengan metode survei terstruktur secara snow ball technique. Survei dilakukan dengan menelusuri para pengumpul daerah, agen serta masyarakat penangkap satwa liar dari mulai daerah Nangro Aceh Darusalam hingga Rantau Prapat. Hasil penelitian menunjukkan bahwa kegiatan penangkapan ular di wilayah Sumatera merupakan suatu kegiatan yang melibatkan cukup banyak anggota masyarakat. Secara kualitas, kemungkinan telah terjadi penurunan pada ular P. reticulatus, tetapi belum begitu tampak pada ular P. brongersmai dan P. curtus. Namun dari segi populasi tangkapan untuk semua kelompok ular tersebut ada kecenderungan penurunan dibandingkan dengan masa sepuluh tahun yang lalu, walau secara kuantitas masih perlu dilakukan perhitungan yang lebih mendalam lagi

ANALISIS ISI PERUT DAN UKURAN TUBUH ULAR JALI (Ptyas mucosus)

Sidik, I. 2006. Stomach contents and body size in common rat snake (Ptyasmucosus). Zoo Indonesia. Vol. 15 (2): 121-127. Climatic changed from drought (dry)to rainy (wet) season is represent the active habit for foraging food of common ratsnake (Ptyas mucosus). Farm, garden and rice fields which still widespread in centraland east Java provinces area have common known by resident as living place of thissnake. This study was to examine the stomach contents of live common rat snakesusing dissecting and flushing stomach contents that were modified. Liquid componentsuch as juicy composite was identified from stomach contained carbohydrate (14.7%),cellulose (30.85%), and lignine (12.43%). Whereas solid materials consist of insect(12.76%), partly body of toads, frogs and skinks, and mammals fur. Unidentifiedmaterials (29.26%) composed of very small particles, most probably grains and plantseeds. Ecology data concerning habitat availability of common rat snake was used ascomparison data to extrapolate of foraging area. Generally, common rat snake get itsfood source from agriculture area. This matterial was known from mixture of element ofplant fiber in composite of digestible animal. There wass possibility that amphibian asa important interconnected food with their ecology

Tinjauan Pemanfaatan Ranggah Rusa dan Karapas Kura-kura Air Tawar Di Propinsi Papua

In Papua, rusa deer (Rusa timorensis) and freshwater turtles constitute the local people bush meat resources through hunting. These hunting activities are produced some by-products i.e. hard antlers from deer and carapace shells from freshwater turtles, where both have a high economic value. The purpose of this study was to investigate the level of production of those by-products and the pathway of the local market being established. The study was conducted at Merauke Regency, Papua, and its vicinity by visiting the key players of all collectors and trade levels. The results showed that on almost all harvested bush meat came from freshwater turtles were cooked on the location, leaving only the carapace shells. Only small quantity of the bush meat was taken home or for trading purposes. However for deer, the majority of hunting activities was done on the purpose for the meat to be sold in the market and small quantity was used for personal needs. Trading on the by-products was conducted at three levels, they were local collectors, middle collectors and local exporter. In general, over 62% of hard antlers samples being observed were uncast hard antlers and 88% of the hard antlers came from the third growth onwards. In a year, at least 1.600-3.700 pairs of hard antlers were acquired, or equivalent to 2.8-6.6 tons. The freshwater turtles being identified were Macrochelodina parkeri, Chelodina reimanni, Macrochelodina rugosa, Elseya braderhorsti and Emydura subglobosa, in which none of the species is under Appendix CITES's list or as Indonesian protected species

The Linnaeus’s Reed Snake, Calamaria linnaei Boie (Squamata: Colubridae: Calamariinae) from Ijen Plateau, East Java, Indonesia

The decisive morphological character of Calamaria linnaei from the Ijen plateau was analyzed in an attempt to evaluate these snakes independently achieved as different populations or whether more likely only cryptic species affected by natural conditions. The evidence was concluded that a cryptic species is very interesting to be regarded as something entirely different. In general, however, the population appears to have more closely related to other congeners populations of the same species. It is suggested that at least temporarily, the C. linnaei population of the Ijen plateau be specifically considered to include in species with high individual variations based on limited geographic boundaries until molecular analysis proves it

Rapid Assessment on Biodiversity in Logged Forest of Tesso Nilo, Riau Province, Sumatra

Tesso Nilo area which is located at Riau province covers an area of 188.00 ha. Recently, it is famous because of asharply increased in encroachment activities for forest conversion, especially for oil palm plantations and villagesites. It was conducted in logged forest around Segati river, Toro river, Mamahan river and Sawan river in June2003. The results showed that the area had the high richness of plant species which was indicated by the high valueof Mennhenick index. Records from the 1 ha studied plot identified a total of 360 species included 165 genera and57 families with 215 tree species 305 sapling species. Some important tree species which were included in the RedList of IUCN were ‘gaharu’ (Aquilaria malaccensis), ‘ramin’ (Gonystylus bancanus), Shorea spp. and Dipterocarpusspp. The local community utilized 83 species of medicinal plants and 4 species of toxic plants for fishing. The totalnumber of recorded bird species was 114 species represented 29% of the total Sumatran bird species. The mostimportant bird species were the Wrinkled Hornbill (Aceros corrugatus), Crestless Fireback (Lophuraerythrophthalma), Crested Fireback (Lophura ignita) and Hooked-billed Bulbul (Setornis criniger). The total numberof recorded mammal species was 34 species or 16.5% of 206 species of Sumatran mammals. The most importantmammal species included Sumatran tiger (Panthera tigris sumatrae), Sumatran elephant (Elephas maximussumatrensis), the Sun bear (Helarctos malayanus) and three species of primates: Hylobates agilis, Presbytis femoralisand Macaca nemestrina. The herpetofauna contained 15 reptile species and 18 amphibian species. The mostimportant herpetofauna was the endangered False Gharial (Tomistoma schlegelii) and the vulnerable Common Softshelledturtle (Amyda cartilaginea). The number of recorded fish species was 50 represented 18% of the totalSumatran fish species (272 species). The important fish species were Breinsteinea sp. and Chaca bankanensis whichwere unique and rare. Since insects are the largest group of animal, this study only focused on beetles. Theidentified beetles were classified into 644 species and 34 families. The important beetles were the Longhorn beetles(Cerambycidae) and the Scarab beetles (Scarabaeidae).The small mammal parasites consisted of ectoparasites whichwere categorized into 14 species and endoparasites which were categorized into 2 orders and 3 species

Found but forgotten: On the records, misidentification, and potential rediscovery of the rare Bromo Tengger Semeru mountain endemic snake (Serpentes: Colubridae: Tetralepis fruhstorferi)

Tetralepis fruhstorferi is a snake currently only known to be endemic to a single active volcano complex of Bromo Tengger Semeru National Park in East Java of Indonesia. Its taxonomic identity and natural history are poorly known, as the most recent collection was in 1978 and limited to only a few collection records. We investigated two recently published surveys that have misidentified this species. This may indicate that T. fruhstorferi is still present in its type locality and our future surveys would focus on finding this species to assess its taxonomy and population status

An inventory of reptiles and amphibians in North-west of SiberutIsland, West Sumatera

Sidik. I. 2008. An inventory of reptiles and amphibians in North-west of SiberutIsland, West Sumatera. Zoo Indonesia 17(2): 35-47. Siberut island is the largest landarea of the Mentawai Archipelagos, in West of the Sumatera Island. Its preservation isof the utmost important to the conservation of tropical forests island. The survey ofherpetofauna was conducted at the inland forest in North-west Siberut island. A totalof 73 specimens were collected consisted of 26 species of reptiles (5 species of agamids,4 species of geckos, 5 species of skinks, 1 species of varanid, 7 species of snakes, 2species of freshwater turtles & 2 species of marine turtles) and 11 species of amphibians(1 species of toad, 1 species of tree hole frog, 6 species of frogs, 1 species of puddlefrog & 2 species of tree frogs). Comparative results of these collections with previouspapers revealed that the existing data of herpetofauna in Siberut was probably atintermediate in number to Sumatera and Malay Peninsula species

REVIEW OF THE MORPHOLOGY OF TRIMERESURUS BROGERSMAI (SERPENTES: CIPERIDAE), A RARE PIVIPER OF SIMEULUE AND THE MENTAWAI ISLANDS, INDONESIA

Trimeresurus brongersmai is a rare pitviper from Simeulue and the Mentawai Islands. We comment on the morphology and examine new specimens from Siberut Island. The four new specimens differ morphologically from the eight specimens known previously. A distinctive banding pattern on the distal tail characterises T. brongersmai and the related species T. puniceus. Juveniles lack the distinctive projecting supraoculars of adult T. brongersmai and these scales apparently develop during ontogeny. We propose the new term “rostronasal†for a large scale positioned between the rostral and nasal on each side of the snout in this species. In addition, we discuss several features of this species that were not mentioned in earlier accounts
