Michael Harper for redOrbit.com — Your Universe Online New research suggests polar bears and brown bears come from the same DNA as ancient bears. In an international study, led by Penn State University and the University at Buffalo, researchers have found that polar bear populations changed with climatic events over the past million years, with fewer polar bears roaming the Earth in times of warmer weather. This new research also suggests the relationship between brown bears and...

Polar Bears Turning To Cannibalism To Survive

One prominent wildlife expert and photojournalist has gathered pictures proving that arctic polar bears trapped on land will turn to cannibalism in order to survive. Jenny Ross, described by UPI as an environmental photojournalist, witnessed a polar bear eating what she initially believed was a seal carcass, then dragging it across the ice at Olgastretet, a stretch of water in the Svalbard archipelago in northern Norway. However, as she got closer, she realized that it was, in fact, the...

A federal scientist under internal investigation, apparently over a study on polar bear deaths that was cited by Al Gore in "An Inconvenient Truth", went on the offensive Thursday, filing a complaint alleging persecution from within the Interior Department, MSNBC is reporting. Charles Monnett, Anchorage-based scientist with the U.S. Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE), had earlier been questioned by investigators about the study he co-authored and was then...

As their icy Arctic habitat melts, polar bear mothers and their cubs are forced to swim long distances, which expose the cubs to higher mortality rates than cubs who do not have to swim as far, a study shows. "Climate change is pulling the sea ice out from under polar bears' feet, forcing some to swim longer distances to find food and habitat," co-author of the study, Geoff York of World Wildlife Fund (WWF), told Reuters. Polar bears are not naturally aquatic creatures. They rely on ice or...

A team of international scientists has found that all living polar bears descend from a single mama brown bear that lived 20,000 to 50,000 years ago in modern-day Ireland.The scientists from Britain, Ireland and the U.S. analyzed DNA samples from polar bears in Alaska, Canada, Greenland, Norway and Russia, and compared them to DNA obtained from teeth and skeletons of 17 ancient brown bears that were found at eight cave sites across Ireland. The results revealed that every individual Polar...

A District Court Judge has ruled that the US Fish and Wildlife Service acted correctly in listing polar bears as a threatened species, rebuffing a pair of opposing legal challenges to the creature's classification on the endangered species list. Environmental groups, including the Center for Biological Diversity, sued claiming that global warming and melting sea ice should afford the polar bear greater protection on the endangered list, while the state of Alaska and Safari Club International...

Russia, reneging on an agreement made with the United States allowing a quota of 29 polar bears to be hunted, posted a statement on its website saying it will not allow the animals to be hunted in its far north polar region. "A decision has been taken on the government level that Russia will not be using its quota," said the statement found on the personal website of Prime Minister Vladimir Putin. A deal reached by a Russian-US commission was approved last month by the Chukotka governor to...

University of Alberta researchers P©ter Molnár, Andrew Derocher and Mark Lewis studied the reproductive ecology of polar bears in Hudson Bay and have linked declining litter sizes with loss of sea ice.The researchers say projected reductions in the number of newborn cubs is a significant threat to the western Hudson Bay polar-bear population, and if climate change continues unabated the viability of the species across much of the Arctic will be in question.Using data collected since...

Scientists studying polar bears around the Beaufort Sea, north of Alaska, were amazed to witness one polar bear that swam continuously for more than nine days, covering some 426 miles, in search of sea ice. The scientists said this endurance feat could be the result of climate change. Polar bears are known to swim between land and sea ice floes to hunt seals. But the researchers said that increased sea ice melts push polar bears to swim much farther, risking their own health and future...
