Roosting behavior and roost selection by Epomophorus gambianus (Pteropodidae) in a west African rural landscape

Urbanization is driving many species to inhabit modified landscapes, but our understanding of how species respond to this remains limited. Bats are particularly vulnerable due to their life-history traits but have received little attention. We describe the roosting behavior and roost site selection, including maternity roosts, for the Gambian epauletted fruit bat (Epomophorus gambianus) within a modified forest-savannah transition ecological zone in Ghana, West Africa. We compared characteristics of roost and non-roost sites to test the hypotheses that roost site selection is non-random and that maternity roost site selection differs from non-maternity roosts. Male bats were more likely to switch roost (mean= 0.49 ± 0.23 bat days, N=23) than females (mean= 0.33 ± 0.18 bat days, N=7) while linear distances between roosts used by males (255 ± 254 m) were significantly longer than for females (102 ± 71m) (t = 4.50, df =86, P <0.0001). Roost trees were more likely than non-roost trees to...
