[quote:Anonymous Coward 826414:MV85MzI5NDBfMTQ2MDM4MTlfRDg5MzZCNEY=] from today folks! here in the tundra.... Is devoured polar bear cub a victim of global warming or act of nature The gory photos of male polar bears devouring cubs, dragging shredded carcasses around and creating a bloody mess on the white snow of Canada's North have caused a stir on the Internet and in reports that link the activity to climate change. But cannibalism among the species is a natural occurrence, says one expert, disputing what is just the latest story to put the polar bear in the debate over man-made global warming. http://www.nationalpost.com/news/story.html?id=2323083 [/quote]
Original Message
Scientists say shrinking Arctic sea ice may be forcing some hungry polar bears to cannibalize bear cubs.
At least seven cases of mature male polar bears eating bear cubs have been spotted this year among the animals around Churchill, Man.
Ian Stirling, a retired Environment Canada biologist who specializes in the Churchill bears, calls it the highest incidence of cannibalization he has ever seen.
Stirling says evidence suggests the cubs are being killed for food, not just so the male can mate with the sow.
He says the Hudson Bay sea ice, which the bears use to get at the seals they need to fatten up for winter, isn't appearing until weeks later than it used to.
