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

摘要: Despite the key importance of landscape matrix for bats, we still not fully understand how effect forest composition interacts at combined stand and scales to shape bat communities. In addition, lack detailed knowledge on effects local habitat structure bat-prey relationships in forested landscapes. We tested assumptions that (i) has interacting bats between scales; (ii) mediates prey abundance activity. Our results indicated conifer-dominated landscapes (> 80% coniferous forests) activity was higher stands with a proportion deciduous trees while were less active mixed (~ 50% forests). Moth selected best models six among nine species. The positive moth Barbastella barbastellus mediated by vegetation clutter, dense understory cover likely reducing accessibility. Altogether, our findings deepen understanding ecological processes affecting strengthen need consider both context trophic linkage when assessing stand-scale compositional structural attributes bats.
