WASHINGTON : An isolated population of polar bears in Greenland has made a clever adaptation to the decline in the sea ice they depend upon as a platform for hunting seals, offering a ray of hope for this species in at least some locales in the warming Arctic.
They were found to be the world's most genetically isolated polar bears, distinct from the species' 19 other known populations. They have been almost entirely cut off from other polar bears for at least several hundred years, with no evidence of any leaving, though some evidence of an occasional arrival from elsewhere.
Polar bears, numbering roughly 26,000 in all, are particularly imperiled by climate change as rising temperatures reshape the Arctic landscape and deprive them of their customary sea-ice platform for hunting their main prey, ringed seals and bearded seals. "This use of glacier ice has not been documented before and represents a unique behavior," said John Whiteman, chief research scientist for the conservation group Polar Bears International and a biology professor at Old Dominion University in Virginia, who was not involved in the study.
