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.

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.
