Federal Study Finds Chukchi Polar Bears Thriving
A federal study says polar bears in the Chukchi are thriving for now despite a loss of sea ice.
ANCHORAGE- A federal study says polar bears in the Chukchi (chuk-CHEE') are thriving for now despite a loss of sea ice.
A U.S Fish and Wildlife Service study indicates bears in the sea between northwest Alaska and Russia are as healthy as 20 years ago.
Polar bears spend most of their lives on sea ice. They have been added to the threatened species list because of sea ice loss.
Biologist Eric Regehr reports that Chukchi bears have maintained their size and body condition despite significant sea ice loss.
That's in contrast to polar bears in the Beaufort Sea off Alaska's north coast, where U.S. Geological Survey studies indicate food is less easy to find.
Male Chukchi bears averaged 100 more pounds than Beaufort bears.
