Bat responses to changes in forest composition and prey abundance depend on landscape matrix and stand structure

Abstract Despite the key importance of the landscape matrix for bats, we still not fully understand how the effect of forest composition interacts at combined stand and landscape scales to shape bat communities. In addition, we lack detailed knowledge on the effects of local habitat structure on bat...
