Canada's western Hudson Bay could lose its population of polar bears (Ursus maritimus ) in as little as a decade, according to new research by biologist Andrew Derocher and others from the University of Alberta (U.A.).
Derocher tells Yale Environment 360 that the polar bears in western Hudson Bay have lost 25 percent of their population in the past three decades. During that time, the animals' average body weight has dropped by 27 kilograms and females have lost 10 percent of their body length.
