Hungry polar bears turn to seabird eggs

Science: Polar bears are known for dining on whatever they want, from human garbage to reindeer to berries. But in the lower latitudes of the Canadian Arctic, they primarily prey on ringed seals (Pusa hispida), hunting them from sea ice platforms. Over the past 3 decades, however, the sea ice in this region has progressively broken up earlier than in the past due to climate change. The bears now face 2 months of ice-free habitat. Without seals to eat, the bears have increasingly turned to terrestrial prey,...
Polar Bears 'More Resilient' To Climate Change Than Thought,

International Business Times: Polar bears are regularly thought of as being among the animals most burdened by climate change, often painted as starved creatures floating aimlessly on shrinking icebergs. But new research is depicting the Arctics greatest predator as one that can actually adapt pretty well to a changing climate, at least when it comes to modifying its diet. Recent research of polar bears diets has produced a vast body of evidence that the bears are turning to other sources of sustenance in times when seals,...

Polar bears hunt on land as ice shrinks
2014-01-24 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Polar bears have shifted to a diet of more land-based food in response to climate change and melting sea ice in the Arctic, new research finds. The results suggest that polar bears, at least in the western Hudson Bay area, may be slightly more flexible in the face of climate change than previously thought. "We found they were eating more of what is available on the land," including snow geese, eggs and caribou, said study co-author Linda Gormezano, a vertebrate biologist at the American Museum...
As More Arctic Ice Melts, Polar Bears Get Creative to Feed Themselves

Nature World: As warming temperatures change the landscape of the Arctic, polar bears there are showing remarkable resiliency in surviving by changing their diet to accommodate, according to recent research. Historically, polar bears' prey of choice are ringed seal pups. But as a warming climate causes Arctic sea ice to melt quicker each year, it limits hunting opportunities for polar bears, who venture out on the ice in search of prey. A group of researchers from the American Museum of Natural History observed...

Scientist settles in iconic 'drowning polar bears' row with US agency
2013-12-04 23:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: An Alaska scientist whose observations of drowned polar bears helped galvanize the global warming movement has retired as part of a settlement with a federal agency. Charles Monnett was briefly suspended in 2011 from his work with the US Bureau of Ocean Energy Management, Regulation and Enforcement -- now known as the Bureau of Ocean Energy Management --during an inspector general's investigation into a polar bear research contract he managed. Investigators in their report released last year said...
