Multi-Scale Roost-Site Selection by Evening Bats on Pine-Dominated Landscapes in Southwest Georgia

Macrohabitat factors affect day roost selection by eastern red bats and eastern pipistrelles in the southern Appalachian Mountains, USA

“…We plotted points in the GIS, calculated the maximum distance traveled between two successive locations for each bat, and then determined mean maximum travel distance for each species. To identify available habitat types within the range of roosting bats, we defined a study area by creating a 100% minimum convex polygon (MCP) for each species using all roost locations and buffering this with mean maximum travel distance moved by that species (Miles et al, 2006). Within the boundary of the buffered MCP, we generated a random point for every roost location, replacing any random points that fell on non-USFS property.…”

Day-roost tree selection by northern long-eared bats—What do non-roost tree comparisons and one year of data really tell us?

“…Selection typically is assessed through comparisons of day-roosts to other trees (hereafter ''non-roosts'') on the landscape, either by random selection or examination of potentially available day-roosts assumed to be unoccupied. Non-roosts used for comparison historically have been those measured in radius plots (Lacki and Schwierjohann, 2001), belt transects (Ford et al, 2006;Silvis et al, 2012) or are paired randomly selected trees (Johnson et al, 2009;Miles et al, 2006;Perry and Thill, 2007). Statistical analysis of selection generally is conducted using a set of candidate models representing combinations of measured tree and/or landscape characteristics that may distinguish day-roosts from non-roosts.…”

Sex-specific roost selection by adult red bats in a diverse forested landscape

“…Because males of many cavity-roosting forest bats typically roost alone whereas females roost in colonies during summer (e.g., Broders and Forbes, 2004;Miles et al, 2006), sex-specific differences in roost selection might be expected for those species. However, potential differences in roost selection between sexes of Lasiurus (which typically roost alone) are not obvious.…”
