Discover the fascinating world of animal winter homes! This lecture explores hidden dens called hibernacula. Learn how animals share these cozy quarters (or go solo), where they hide in plain sight (burrows, caves), and which creatures use them (not all hibernate). We'll delve into winter alliances & rivalries, how climate change affects hibernation, and how this strategy shapes evolution. Uncover the surprising connections between winter slumber and the intricate web of life in northern Michigan.
