Virginia scientists discover the cues black bears use for hibernation

So, researchers at Virginia Tech have uncovered that black bears use both temperature and daylight cues for hibernation, which is more complex than previously thought. They studied four pregnant bears over 22,000 hours of footage and found that these environmental factors interact significantly. Interestingly, while temperature drives the initial hibernation, the combination of light and temperature influences their behavior during other phases. This research is crucial for understanding how climate change might disrupt these natural signals and affect bear behavior in the future.
