Ice Drift Causing Polar Bears To Work Harder For Food
- 8 years ago
Recently presented research has found that ice drift in Alaska is causing bears to walk more to remain in their habitat and hunting ground which causes them to burn more calories but makes it more difficult for them to capture prey.
Warming temperatures in the Arctic are requiring polar bears to put more effort into sustaining themselves.
Research led by the Alaska Science Center of the U.S. Geological Survey, or USGS, has found that that animals are having to expend more energy to remain in the same hunting area because the melted ice below them is drifting.
The primary researcher, David Douglas, compared this to
