Social Organization of a Maternity Group in the Noctule Bat, Nyctalus noctula (Chiroptera: Vespertilionidae)
Abstract Social organization of a captive group of noctule bats, N. noctula , was studied by frequent censuses of bats at roost sites during one summer season. Numerous nonrandom associations as measured by information indices of similarity (Kullback 1959; Semkin 1972; Zakharov et al. 1987) were fou...
