Comparison of the Ranging Behavior of Scotophilus kuhlii (Lesser Asiatic Yellow Bat) in Agricultural and Urban Landscape

摘要

Knowledge on home range sizes and movement patterns of animals through the environment is crucial for determining effects of habitat disturbance and fragmentation. To gauge the effects of land-use changes on Scotophilus kuhlii, a telemetric study was conducted between February 2014 and April 2014 in Tasik Chini, Pahang and Universiti Kebangsaan Malaysia (UKM), Bangi Campus. The home range sizes and movement patterns of S. kuhlii inhabiting agricultural landscape (Tasik Chini, Pahang) versus urban landscape (UKM) were compared. A total of ten individuals were successfully radio-tracked. Comparison of home range sizes of both sexes showed male S. kuhlii at Tasik Chini have larger mean home range sizes compared to UKM while female S.kuhlii in UKM have larger mean home range sizes compared to Tasik Chini. All individuals from both localities showed random movement. It is suggested that the home range and activity patterns might be influenced by food availability in the study area, food preferences and diet segregation and breeding behavior. This study provides baseline information on habitat utilization by S. kuhlii in relation to habitat perturbations.
