Abstract
We used radiotelemetry to investigate the temporal patterns of activity, characteristics of activity areas, and the spatial relationships among activity areas, day roosts, and water for female long-eared myotis (Myotis evotis). We tracked 12 adult female long-eared myotis for 23 nights from June to August, 1996 and 1997, on the western slope of the Cascade Mountains in Oregon, USA. The activity areas of nine bats (n=11 nights) averaged 38.3 ha and were centred an average of 518 m from the day roost (SE=60 m) and 73 m from water (SE=10 m); centres of activity were significantly closer to water than random points (P<0.001). Odds of an area being used decreased with distance to available water (P=0.0001). Activity areas typically encompassed water but did not include the day roost. Activity areas did not significantly differ in forest composition as determined from randomly selected circular plots. Bodies of open water appear to function as important centres of activity for long-eared myotis. We contend that management of habitats for bats should consider spatial relationships among activity areas, day roosts and water.
