Individual Variation in Overwintering Strategies of the Great Evening Bat (Ia io) in Subtropical China 中国亚热带地区大足蝠 (Ia io) 越冬策略的个体差异

Wildlife Letters, EarlyView.
Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...
