其他摘要：The paper presents the results of the 20-years research (1994–2013) of bats wintering in the underground artillery caverns, built as Bratislava city defense during the years 1914–1915. In 31 caverns (out of the 48 known caverns) the presence of bats was recorded. Altogether 10 bat species were observed in studied sites (Rhinolophus hipposideros, Myotis myotis, Myotis bechsteinii, Myotis nattereri, Myotis mystacinus/brandtii, Myotis daubentonii, Eptesicus serotinus, Barbastella barbastellus, Plecotus auritus and Plecotus austriacus) with a frequency of 1–9 individuals per one control and site.
