The bat community of the Sloupsko-šošůvské jeskyně cave (a natural karstic cave, Moravian Karst) was studied using two methods, a regular winter census of hibernating bats and netting at the cave entrance. In total, 15 bat species have been recorded. The bat community is characterised by a significant dominance of Myotis myotis in both seasons (58.5 % and 53.8 %, respectively). The changes in numbers of hibernating bats have shown a similar trend to that found in other caves or regions, viz., a strong increase of M. myotis and a stabilization of Rhinolophus hipposideros population with subsequent increase (late 1990s). The maximum abundance of bats in the cave during hibernation was recorded in early March (3 March 1993 – 482 ind.). The highest intensity of cave visitation occurred in the C period (from 15 July to 14 September). M. myotis individuals occupied only one specific part of the cave system during hibernation (80% of findings), while all parts of the cave were used by R. hipposideros.
