Last week I published a blog post where I set out to answer the question of whether polar bears are facing impending extinction due to climate change or are they, in fact, doing better than ever. Around the time when I was investigating this question, I got in touch with Professor Andrew Derocher from the Department of Biological Sciences at the University of Alberta, who has studied polar bears for over 40 years. He specialises in ecology, conservation, and management of large Arctic mammals with a particular focus on polar bears. So, of course, I couldn’t miss the opportunity to sit down with him for a comprehensive chat about all things polar bears.

During our conversation, we talk about the limiting and regulating factors of polar bear populations. Those include habitat use, predator-prey relationships, the effects of climate change as well as the accumulation of toxic chemicals in the 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.

Finally, you might want to check Andrew’s book: “Polar Bears: A Complete Guide to Their Biology and Behavior”. And, by purchasing it using the link provided, you will help support my work since I receive a tiny commission on each sale made.
