Abstract

Kura-kura Sulawesi (Leucocephalon yuwonoi McCord, Iverson and Boeadi, 1995) adalah satu dari sekian banyak kura-kura yang paling sedikit diketahui dan paling jarang di dunia. Pada tahun 1995 yaitu tahun pertama ditemukan, kura-kura ini telah membanjiri restoran di daratan utama Cina, dan oleh IUCN-The World Conservation Union  populasi kura-kura  ini dikategorikan kritis. Penelitian ini untuk mengungkap tingkat eksploitasi dan status kura-kura Sulawesi yang dilakukan di kawasan utara Sulawesi Tengah dari tanggal 28 April sanpai 13 Mei 2002. Penelitian dilakukan dengan dua pendekatan yaitu (1) survei menggunakan garis transek pada habitat yang merupakan kawasan anak sungai dan (2) kunjungan kepada para pemburuh atau kolektor untuk mendata jumlah kura-kura yang ditangkap. Hasil penelitian ini menunjukkan bahwa tingkat eksploitasi kura-kura Sulawesi pada tahun 2002 diperkirakan mencapai 720 ekor dan status populasinya dinyatakan langka dengan frekuensi 1,91 per hari. Hasil penelitian  berhasil pula mengungkapkan lokasi baru pada  penyebaran kura-kura Sulawesi.

Abstract

Cyrtodactylus marmoratus is one of the first species described by Gray in 1831 on the island of Java that believed to have a variation of morphologic characters that not yet complete to revealed. This research aimed to develop any variation characters possessed by Cyrtodactylus marmoratus. The character morphology, morphometric, and meristic follow the statement of Hartmann (2016). Data were collected in August to November in the Lab. Herpetology MZB (Museum Zoologicum Bogoriense) LIPI (The Indonesian Institute of Sciences). Variation characters possessed  by Cyrtodactylus marmoratus, there are 4 Characters Morphology: Head Morph (HM), Patern Morph on the Body (PtrM), Post Cloacal Tubercles (PCT), and second post mental (PM2); a Morphometry Characters is snout-vent Length (SVL); and 12 characters Meristic are: Precloacal Pores (PP), Precloaco-femoral Pores (PFP), Enlarged Precloaco-femoral Scales (EPFS), Ventral Scales (VS), Paravertebral Tubercles (PVT), Dorsal Tubercles (DTR), Lamella Under Toe-IV (LT4), Lamella Under Toe-V (LT5), Lamella Under Finger-III (LF3), Lamella Finger-IV (LF4), Femoral Pores Left (FPL), Femoral Pores Right (FPR).

Abstract

A study of Agamid lizards diversity and their distribution surrounding Martabe Mining project Area, South Tapanuli, North Sumatera was conducted in five different habitat types. The data were gathered by opportunistic searching in each habitat type with two replications. Shannon-Wiener index was used to determine the diversity while the homogeneity was verified by Pielou index. The similarity of Agamid communities among habitat types was confirmed by Sorensen coefficient. As a result, 9 Agamid species were recorded with Draco melanopogon as the major component of Agamid community making up 49.1% of total individuals gathered. Highest diversity occurred in moderately disturbed forest, but the most homogeny took place in riparian lowland forest. The cluster analysis using Sorensen’s coefficient of agamid species distribution among habitat types distributed the habitats into three major groups, with the most similarity occurred between primary and riparian lowland forests (75%). The identification key of the species was made.

Abstract

Kura-kura Sulawesi (Leucocephalon yuwonoi) adalah satu dari dua jenis kura-kura endemik Sulawesi dengan penyebaran yang terbatas. Sejauh ini data natural historinya sangat minim, padahal sangat dibutuhkan dalam upaya penangkaran satwa yang berstatus kritis IUCN ini. Penelitian ini bertujuan untuk mengungkap tentang pakan di alam beserta kandungan nutrisinya. Survei lapangan dilakukan di kawasan Bangkir dari tanggal 23 Mei sampai 5 Juni 2004 dan di Moutong dari tanggal 11 sampai 19 Oktober 2004. Data pakan di alam diperoleh dari analisis sampel feces dan hasil wawancara kepada para pemburu kura-kura beserta pengumpul. Kepastian nama jenis pakan diperoleh dengan melakukan identifikasi sampel tumbuhan pakan di Herbarium Bogoriense. Data kandungan nutrisi diperoleh melalui analisis proksimat sampel pakan yang terkoleksi selama survei. Hasil penelitian ini menunjukkan bahwa terdapat 32 jenis tumbuhan yang jadi sumber pakan di alam, variasi kandungan nutrisi yang cukup besar, kandungan lemak rendah berkisar antara 0.74 - 8.33% (2.41+2.03) dari berat kering. Berdasarkan dominansi, keberadaan di habitat (multiple season) dan tingginya kandungan energi diduga kuat bahwa Colocasia esculenta, Limnocharis flava and Ipomoea aquatica merupakan pakan utama di alam.

ABSTRACTMorphological Study of Larvae and Infection Pattern of Falcaustra kutcheri Bursey et.al.,2000 in Leucocephalon yuwonoi Mc Cord et.al., 1995 from Sulawesi. Some nematode parasitesFalcaustra kutcheri Bursey et.al., 2000 were found in alimentary tract of Leucocephalonyuwonoi, those were large in numbers in rectum and a small numbers in stomach. Both adultand larvae were collected from the host. The larvae were different on mouth structure and theshape of esophagus. An additional character, i.e two lateral branches of the anterior part ofintestine, that appear along the growth of larvae were reported.Key words: Nematode, Falcaustra kutcheri, infection pattern, larvae, morphology,Leucocephalon yuwonoi, Sulawesi

Abstract

ABSTRACTHerpetofaunal Community Structure of Ciremai Mountain National Park, WestJava. Distribution and broad habitat associations of the herpetofauna on four limitedsites of Ciremai mountain, west Java, Indonesia were studied. The field surveys wereconducted on Apuy-Arban site from 7 until 21 April 2006 and from 6 until 10 March2007, Linggarjati site from 10 until 15 February 2007 and from 19 May until 2 June2007, Seda forest from 18 until 24 February 2007 and Palutungan site from 26 Februaryuntil 4 March 2007. A variety of methods were employed to sample the herpetofauna. Atotal of 43 amphibians and reptiles taxa were recorded, comprising 16 frogs, 18 lizardsand 9 snakes. Two of them were endemic to Java, they are Huia masonii and Microhylaachatina. Unidentified and possibly undescribed species of unusual specimen referred tothe genus Elapoidis. From this study, three habitat were clustered and divided into twomain habitat zones for herpetofauna.Key words: amphibians, reptiles, gunung Ciremai.

Abstract

ABSTRACTThe Habitat Characteristic of the Critically Endangered Turtle the Sulawesi ForestSulawesi Turtle Leucocephalon yuwonoi in Ganonggol and Bangkir Rivers in CentralSulawesi. The Sulawesi Forest Turtle (Leucocephalon ymonoi) is an endemic, criticallyendangered and listed in the appendix I1 of CITES. Captive breeding is needed toreintroduce the species into the original habitat. Captive breeding success includes acomprehensive knowledge on the biology and ecology of the species. The objective ofthis research is to investigate the habitat character of the turtle respectively vegetation ofthe riverbank, physical and chemical conditions ofthe water. Field surveys were conductedon the Moutong area from 1 l until 19 October 2004 and on the Bangkir area from 20until 26 October 2004. Vegetation data were obtained by developing four quadrate at theturtle habitat in each locality and were analyzed using Curtis method. The results shownthat the habitat of Leucocephalon yuwonoi is transparent streaming water, neutral, nottoo high dissolved oxygen, water height not more than 50 cm, substrat varies from bigstones, small stones, clay loam and sandy loam. The area was covered by vegetation thatcan provide food during all year round, such as Colocasia esculenta, Limnocharisflava,and Ipomoea aquatics.Key Word: Leucocephalon yuwonoi, habitat, vegetation, water conditions.

Abstract

ABSTRACTThe Loss and Recent Condition Habitat of Sulawesian Tortoise (Indotestudo forstenii) atCape Santigi, Central Sulawesi, Indonesia. Unsupervised method of remote sensing wasapplied were evaluated to compute the habitat loss during five years, from 2001 to 2005 usingMultispecW32 software. Meanwhile, the fieldwork was done from 22 to 30 June 2007 todetermine the recent condition of habitat at Sologi hill, a part area of Cape Santigi. During fiveyears (from 2001 to 2005) the forest (habitat) in Cape Santigi was loss making up 60.04 % (rate= 419.25 ha/year). Sologi hill forest was shown as a remaining habitat in Cape Santigi. Vegetationin Sologi hill forest is relatively still good, but is threatened by human activities. We suggesteddeveloping the natural preserve to protect this tortoise, habitat and ecosystem also otherwildlife at Sologi hill.Key words: Indotestudo forstenii, habitat, Cape Santigi, Central Sulawesi, Indonesia.
