Arctic melt shrinks polar bears chances
2016-09-25 11:22:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: The world of the polar bear is shrinking everywhere. New research by scientists in the US confirms that each of the 19 known populations of Ursus maritimus is increasingly affected by the earlier sea ice melt in the Arctic spring, and the later arrival of ice every autumn. The finding is hardly a shock, as there have been warnings from conservationists about such things for years, with the polar bear becoming an icon of climate change concerns. And in most cases of species threat there are winners...

Polar bears biggest threat is ice loss

Earth Sky: Prior to the 1970s, hunting decimated polar bear populations across the Arctic. The international community has made strides in protecting the iconic species from over-harvesting through conservation agreements, which have helped the species start to recover. However, a review paper published in Polar Research in July, 2016 suggests that the road to recovery is far from over, as ice loss now replaces poaching as the most pressing threat to polar bear survival in the Barents Sea area, north of Norway...
Brown Bears Use 'Human Shield' to Protect Their Cubs

National Geographic: Brown Bears Use 'Human Shield' to Protect Their Cubs Mother bears have a difficult choice: Take their cubs nearer to humans or risk infanticide by males looking to mate. A mother grizzly leads quintuplets in Katmai National Park in Alaska. New research provides a surprising insight into how mother bears may keep their cubs safe from dangerous adult males. Photograph by Eberhard Brunner, Alaska Stock, National Geographic You might think that winter is the most dangerous...

Grizzlies and polar bears mating more frequently
2016-05-28 23:15:00| Climate Ark Climate Change & Global Warming Newsfeed
Comment: The warmer temperatures have led to expanded territories for the grizzlies to roam and run into polar bear mates, which could lead to polar bears as we know them to dissolve into the grizzly population. Grizzlies and polar bears have enough genetic similarity to allow for interbreeding - they are thought to have split off from the same genetic line no more than 500,000 years ago - but scientists have yet to determine if a hybrid bear can reproduce or what their survival rate might look like. "If...
