摘要: In the southern Appalachians there are few data on roost ecology of federally endangered Indiana bat (Myotis sodalis). During 2008-2012, we investigated roosting in ~280,000 ha Great Smoky Mountains National Park, Cherokee Forest, and Nantahala Forest Tennessee North Carolina. We 2 aspects bat’s ecology: thermoregulation extrinsic factors that influence body temperature, landscape-scale selection. To investigate bats at roost, used gathered 2012 from 6 female (5 adults 1 juvenile) to examine how reproductive condition, group size, characteristics, air barometric pressure related temperature bats. found was primary factor correlated with bats’ temperatures while (P < 0.01), differences detected among classes terms thermoregulatory strategies. understand select roosts a landscape-scale, created presence-only model through program MaxENT using 76 known locations identify areas important summer habitat within our study area The final showed selected upper portion ridges south facing slopes mixed pine-hardwood forests elevations 260-700 meters.
