Abstract
Abstract Field study on the murine biodiversity in Lombok Island in early 2020 has spent 581 traps-night efforts in five localities of East Lombok. They were Kembang Kuning, Aikmel, Wanasaba, and Kelayu Jorong. Fifty one individuals have been collected used live trap with dry-salty fish baits. Of those 51 individuals were collected, we successed to indentify five species of murines.They were Rattus argentiventer, R. rattus diardii, R. exulans, R. tanezumi , and Mus musculus castaneus , respectively. R. argentiventer and R Tanezumi were highly abundance and wide-spread species in East Lombok. Surprisingly, R. rattus diardii was only two individuals collected out 100 trap.nights efforts. Those two individuals of restricted to Kembang Kuning. Mus musculus castaneus was the only member of genus Mus collected in this study. This study would be drive our knowledge on the diversity of rat and mice in Lombok Island and their ecology. Furthermore, the prelimary results of this study will allow us for better understand on managing rat and mice population and their interaction with human being.
