Study shows polar bear metabolic rates are higher than previously predicted

(San Diego Zoo Global) A new study on polar bear metabolism, behavior, and foraging success sheds important light on their energy demands. The study, published in the journal Science, found that polar bears have metabolic rates greater than previously predicted and greater than other terrestrial mammals of similar size. The study reinforces the understanding that polar bears are reliant on a diet of fat-rich seals to survive in the energetically-demanding Arctic.
