Media Release: Polar bears act as crucial providers for Arctic species

October 28, 2025 —
A new study published in the scientific journal, Oikos, reveals for the first time the critical role polar bears play as carrion providers for Arctic species. Researchers from University of Manitoba and San Diego Zoo Wildlife Alliance, alongside researchers from Environment and Climate Change Canada, and the University of Alberta, have estimated that polar bears leave behind approximately 7.6 million kilograms of their prey annually, creating a massive and vital food source for a wide network of Arctic scavenger species.
