159: Polar Bears in a Warming World with Andrew Derocher

This episode will answer all your questions about polar bears — including those you didn’t know you had. Our guest is Professor Andrew Derocher from the Department of Biological Sciences at the University of Alberta who specialises in ecology, conservation, and management of large Arctic mammals with a particular focus on polar bears. The subjects discussed include the limiting and regulating factors of polar bear populations, habitat use, predator-prey relationships, the effects of climate change as well as the accumulation of toxic chemicals in bears' bodies. We also explore the issue of polar bear hybridisation with brown bears and how this might impact their population. We ended our conversation with an attempt to predict the future of polar bears in the rapidly warming world.You may also be interested in checking out my blog: “Are Polar Bears Going Extinct or Are Their Populations Doing Better Than Ever?”Subscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Recommended Books: tommysoutdoors.com/booksMerch: tommysoutdoors.com/shopFollow Tommy's Outdoors on Bluesky, Twitter, Instagram, YouTube and FacebookMentioned in this episode:The Hunter Conservationist Podcast brings you nuanced content about conservation, science and responsible hunting in Canada, so you can stay topped up on issues concerning your outdoor, hunting and fishing lifestyle, stay current on the latest in wildlife conservation, science and responsible hunting and be entertained by conversations with intellectual thinkers.The Hunter Conservationist Podcast
