Climate change brings bad news for polar bears
“What we found was striking,” Graham Slater, the lead author of the study said in a release. “The polar bear and brown bear can bite equally hard, but the polar bear’s skull is a much weaker structure.”
The weaker skull means polar bears are likely to lose out on food in competition with grizzlies, whose stronger skulls are better-suited to a plant-rich diet, Slater said.
Study author Blaire Van Valkenburgh said polar bears being forced south may mean lower birth weights, smaller and fewer litters, less reproductive success and fewer bears surviving to adulthood.
I haven’t seen any Polar Bears around here yet, but I will keep my eyes open.
