Sažetak
The Veternica Cave is open for visitors and run by the Medvednica Nature Park. It is located near Zagreb, the capital of Croatia, and is one of the key bat spots for the northwestern part of Croatia. The total length of the cave passages is nearly 7, 000 m with very different microclimate conditions. The first 400 m are accessible for tourists and are under the influence of external climate. There have been 14 bat species recorded until now. Rhinolophus ferrumequinum and Rh. euryale form winter colonies and Rh. euryale and Miniopterus schreibersii use the cave as summer roost. Myotis daubentonii, M. nattereri, M. emarginatus, M. myotis, M. blythii and Rh. hipposideros are found in crevices or on cave walls throughout the winter mainly as solitary individuals in colder parts of the cave. During very cold weather the cave provides a valuable shelter for M. bechsteinii, Eptesicus serotinus, Barbastella barbastellus and Plecotus spp. In the winter of 2004, Plecotus macrobullaris was recorded in the cave and that part of Croatia in general, for the first time. Data loggers measuring temperature and humidity at 5 minute intervals are set at 5 sites on the cave walls. Temperature, humidity and wind speed were measured near individual bats. Data on microclimate preferences of different bat species are discussed and compared with data from research conducted in winter of 1995/1996. A significant decrease in the number of R. ferrumequinum and R. euryale has been noted and recommendations for bat conservation through sustainable cave management are offered.
