[Species structure and dynamics of bat communities (Chiroptera: Vespertilionidae) hibernating in artificial caves of Samara Luka].
Long-term data on the composition and absolute and relative abundance of eight bat species hibernating in artificial caves of Samara Luka are considered. About 13,000 hibernating individuals are annually accounted there. The relative abundance of the species decreased in the following order: Myotis brandtii (35%), Plecotus auritus (20%), M. daubentonii (13%), M. mystacinus (13%), Eptesicus nilssonii (8%), M. dasycneme (8%), and M. nattereri (2%). Singular E. serotinus were recorded not every year. The number of hibernating animals in pits was proportional to their size and the number of shelters. Bats used previously chosen shelters and were never found in adjacent caves. The maximum species diversity (H') and evenness (E) were observed in bat communities in medium-sized caves. One of the main factors of increasing abundance of hibernating bats in abandoned pits is their gradual colonization by the animals.
