<![CDATA[Abstract The bat species biodiversity varies across environments in six different ecosystems based on Vectora 2015 Research Report. These ecosystems were distant forests and near settlements, non forests near and far residential, as well as near and remote coastal settlements. We measured species diversity (Shannon-Wiener index), environmental factors were also measured during bat surveys, ie air temperature, humidity and weather during survey. This paper was a further analysis of Vectora 2015 Research Report. The analysis was aimed to determine the impact of environmental factors to the bat species diversity especially in Tojo Una-Una and Tolitoli District. We found that the temperature and humidity factors significantly affect the diversity of bat species. The highest species diversity found in the forest near settlement, that was 0,3396. Abstrak Data Riset Khusus Vektora tahun 2015 menunjukkan adanya keragaman spesieskelelawar di lokasi riset yang terdiri atas enam ekosistem yang berbeda. Ekosistemtersebut adalah hutan , non hutan jauh dan dekat pemukiman dekat dan jauhpemukiman, serta dekat dan jauh pemukiman pantai . Faktor lingkungan juga diukurpada saat dilakukan survei kelelawar, yaitu suhu udara, kelembaban dan cuaca saatpenangkapan. Tulisan ini merupakan hasil analisis lanjut Riset Khusus vektora tahun2015. Analisis dilakukan dengan tujuan untuk mengidentifikasi pengaruh ekosistemdan faktor lingkungan (suhu, kelembaban dan cuaca) terhadap keragaman jeniskelelawar di Kabupaten Tojo Una-Una dan Tolitoli Provinsi Sulawesi Tengah danperannya sebagai reservoir penyakit zoonosis. Hasil analisis menunjukkan bahwafaktor suhu dan kelembaban berpengaruh pada keragaman spesies kelelawar secarasignifikan.]]>
