How does deadwood structure temperate forest bat assemblages?
International audience Thirty percent of forest species depend on deadwood. Some of them are now considered rare or at high risk of extinction mainly due to an insufficient quantity of deadwood substrates. Some bats roost in dead trees and snags. Because European bats are strictly insectivorous, we...

International audience Thirty percent of forest species depend on deadwood.
