| Description | The fact that WNS is abundant in Europe without the mass mortality of bats as seen in North America led to increased interest of experts in Czech Republic. In our study, we focused on comparing the thermal profile of hibernating bats on two important wintering grounds. Štoly pod Jelení cestou (Jeseníky) are a typical wintering area with a high prevalence Pseudogymnoascus destructans (Pd) (2012 - 59.8%) and Kateřinská jeskyně (Moravian Karst) with a low prevalence of Pd (2012 - 5.0%). Monitoring of hibernating Myotis myotis clusters was performed on both sites using continuous scanning by thermal imagers and snapshot cameras (or IR camera) from January to April over two winters 2012-2013 and 2013-2014. The length of thermal events (heating bat above ambient) and recorded thermal maxima were found to correlate. Also we found the correlation between length of the events and the number of bats involved in the thermal change. Match has been found for shorter events from both locations in thermal variables. However, longer events from both locations are significantly different in thermal variables. Thermal events were longer and reached higher temperatures in Štoly pod Jelení cestou than in Kateřinská jeskyně, where the prevalence of P. destructans is significantly lower. The results of this study suggest that P. destructans have possible impact on European species of bats during hibernation. The research was supported by the Czech Science Foundation P506 / 12 / 1064. |
