Day-roost tree selection by northern long-eared bats—What do non-roost tree comparisons and one year of data really tell us?
Alexander Silvis, W. Mark Ford, Eric R. Britzke
2015, Global Ecology and Conservation (3) 756-763
Bat day-roost selection often is described through comparisons of day-roosts with randomly selected, and assumed unused, trees. Relatively few studies, however, look at patterns of multi-year selection or compare day-roosts used across years. We explored day-roost selection using 2 years of roost selection data for female northern long-eared bats (Myotis...
