Description North American bat species suffering from white nose syndrome (WNS) show a significant difference from healthy individuals in hibernation behavior. Our goal was long-term monitoring of hibernating bats, which would show whether this behavior is different in bats with WNS in the Czech Republic. We used thermal imagers and snapshot cameras during two winters to monitor clusters of greater mouse-eared bat (Myotis myotis) at two locations, Štoly pod Jelení cestou (Jeseníky) and Kateřinská jeskyně (Moravian Karst). During hibernation, we primarily found events related to body temperature rise in individual or group of bats, which led to normothermia (normothermic events). Most normothermic events (64.4%) does not exceed 1.5 hours by length. Normothermic events were not more frequent with the end of winter, as is characteristic in bats with WNS North America. Involvement of a larger number of individuals in the event in most cases resulted in a cascade effect. Events with cascade effect were generally longer lasting. Duration of normothermic events increased with group size or proportion of active individuals. The maximum temperature reached during the events differed between localities and years. Our results show differences in the behavior of the hibernating bats with WNS between Czech Republic and North America while highlighting the specific role of climate and locations that affect the course of hibernation.
