Scientists uncover environmental cues behind black bear hibernation
New research from Virginia Tech scientists in the College of Natural Resources and Environment provides fresh insight into how environmental conditions influence black bear hibernation, with implications for wildlife management in today's environment.
Virginia Tech researchers have discovered how temperature and day length affect the hibernation patterns of black bears, according to new findings published in the Proceedings of the Royal Society B. Doctoral student Brogan Holcombe led the study, which analyzed more than 22,000 hours of video footage captured at the Black Bear Research Center.
The research found that while temperature alone influenced bear behavior during the beginning of hibernation, the combined effects of temperature and photoperiod (day length) were crucial in determining activity levels during other stages. Specifically, temperature impacted the onset of hibernation, while both temperature and photoperiod influenced activity before denning and during emergence.
The researchers suggest that climate change could disrupt these environmental cues, potentially altering hibernation timing and increasing human-bear interactions.
