In brown bears, females that don't have at least 20% body fat when they go into hibernation will not reproduce. She'll actually reabsorb that embryo as if it never happened because she doesn't have enough resources to provide for her cubs. In other circumstances, I guess it might be the opposite, right? If you have a bear that is close to people and that's stressing them out and they feel like they can't get enough access to resources, then reabsorbing that embryo because she's not fat enough may be the best option for her.
Because one bears is not enough bears, SIX more ursinologists join to answer your questions about polar bear fur, monogamy, that scene from "The Revenant" and more. Five chapters of bear life, from mindblowing mating strategies to how bears get from point A to B, media portrayals of these beautiful beasts and how to save them. Also: do bears want you to sing to them? Bear biologists and conservationists Dr. Thea Bechshoft, Dr. Lana Ciarniello, Drew Hamilton, Wes Larson, Tsalani Lassiter & Danielle Rivet field more of the 500 listener questions and it gets… wild.
