Abstract

Sebagai satwa liar yang tersebar luas, kadal dapat dijadikan acuan untuk mempelajari dampak perubahan habitat, teruta-ma untuk beberapa jenis yang dapat bertahan di berbagai tipe habitat dan sensitif terhadap perubahan lingkungan. Tujuan dari penelitian ini adalah menelaah komposisi dan kelimpahan kadal pada berbagai tipe habitat, mengukur perbedaan ukuran tubuh pada tiga spesies dominan, menganalisis kesamaan komunitas dan pemilihan mikrohabitat. Penelitian dilakukan di hutan Nantu, Gorontalo pada bulan Mei-Juni 2014. Survey dilakukan dengan memasang jebakan lem pada transek garis sepanjang 50-100 m pada tujuh tipe habitat berbeda yaitu habitat hutan (hutan sekunder, hutan produksi terbatas dan peralihan hutan ke kebun) dan kebun (kebun jagung, kebun tebu, kebun kelapa dan kebun coklat). Hasil penelitian mendapatkan delapan spesies kadal dari satu famili, dimana tiga spesies dominan dengan kelimpahan tertinggi adalah Emoia caeruleocauda (Spesialis kebun), Eutropis rudis (Sebaran luas), dan Sphenomorphus variegatus (Spesialis hutan). Tutupan kanopi, tutupan tumbuhan bawah, dan sumber air diduga sebagai faktor biotik yang paling berpengaruh terhadap tiga spesies dominan.
