Polar Bears Can Adjust to Global Warming By Changing What They Eat
(p. D2) As a warming climate causes sea ice in the Arctic to melt earlier each year, polar bears are spending more time on land -- and changing their diets accordingly. A new study shows that the bears, whose traditional prey is ringed seal pups, are now eating more snow-goose eggs and caribou.

Samples of scat from different parts of the bay suggest that the bears are highly flexible and willing to change what they eat based on availability.
"Bears along the coast are eating more grass," Dr. Gormezano said. "Further inland they are eating more berries."
