| Description | Hibernating animals entering deep torpor are typically immobile because body temperature is tightly coupled to physiological function. We analyzed thermal behaviour and locomory activity of hibernating greater mouse-eared bats Myotis myotis and found two types of behaviour as related to body temperature: normal body temperature (NBT) and low body temperatute movements (LBT, Tb 5C). The first LBT appeared at the beginning of March and were often in torpor bouts. In most cases LBT episodes represent slow dislacements between clusters of bats, however, in several cases departure or arrivals from/into clusters were recorded without any elevation of body temperature. The ability of bats to move within a hibernaculum under low body temperatures changes our understanding of hibernation principles. We believe that LBT episodes allow bats to save energy and prolong torpor bouts. |
