Polar Bear Genome Provides Clues To Rapid Evolution To High Fat Diet
2014-05-09 05:24:37

redOrbit Staff & Wire Reports - Your Universe Online Mutations in genes involved in cardiovascular function allowed polar bears to rapidly evolve the ability to consume a fatty, blubber-rich diet without developing high rates of heart disease, an international team of scientists reported this week in the journal Cell. Moreover, the study revealed that polar bears diverged from brown bears less than 500,000 years ago – much more recently than estimates based on previous genomic...

This week in Molecular Biology and Evolution Male bears are seemingly always on the prowl, roaming much greater distances than females, particularly for mating. For bear evolution, studying the paternally inherited Y chromosome is therefore a rich source to trace both the geographic dispersal and genetic differences between bear species. This new study is particularly important, because a large part of our current knowledge about range-wide population structuring in mammals relies on...

How Do Polar Bears Keep Warm? It May Be In Their Genes
2014-02-10 14:42:18

Lee Rannals for redOrbit.com - Your Universe Online During the recent polar vortex that swept down into the US, even polar bears in the Chicago zoo had to go inside. However, new research gives more insight into how these animals' Arctic counterparts are able to keep warm in extremely low winter temperatures. The reason the Chicago polar bears had to venture indoors during the deep freeze is due to a diet that is much different from polar bears that live in the Arctic tundra. The latest...

Polar Bear Diets Change Climate Change
2014-01-23 13:03:52

Lee Rannals for redOrbit.com - Your Universe Online Polar bears are able to switch up their diet in order to help them survive the warming Arctic, according to a new study. Scientists at the American Museum of Natural History performed a three-part study that shows how polar bears switch up plant and animal food sources as they face the changing climate. Arctic sea ice is beginning to melt earlier and freezing later each year, so polar bears are having a limited amount of time to hunt...

Croatia joined the European Union on 1 July and conservation scientists fear that the EU's rules could cause problems for its brown bear population. The country has been managing its brown bears as game animals, meaning they can be hunted; but under EU legislation, bears are a protected species and can only be shot if they are deemed to be problem animals. This might seem to be a positive outcome for the bears. However, it could lead to reduced tolerance for bears among local people,...

DNA Study Reveals Secrets Of Gentically Similar Polar And Brown Bears
2013-03-15 10:22:25

Brett Smith for redOrbit.com - Your Universe Online A new report in PLoS Genetics attempts to clarify conflicting studies on a population of Alaskan brown bears that are genetically similar to polar bears, yet look and act like typical brown bears. "This population of brown bears stood out as being really weird genetically, and there's been a long controversy about their relationship to polar bears," said co-author Beth Shapiro, a professor of ecology and evolutionary biology at the...

Polar Bears Threatened By Climate Change, Action Urged Now
2013-02-06 05:34:00

April Flowers for redOrbit.com - Your Universe Online An international group of scientists, led by a University of Alberta polar bear researcher, is urging governments to prepare for rapid Arctic ecosystem change to deal with a climate change catastrophe for the polar bears. University of Alberta professor Andrew Derocher is one of the authors of a policy perspective recently published online in the journal Conservation Letters that urges governments with polar bear populations to...

Mama Bear Knows Best When Picking Out Homes
2013-01-22 14:55:49

Lee Rannals for redOrbit.com — Your Universe Online Husbands should be taking a clue from nature when it comes to looking for a home, as new research emerges that shows mama bear knows her stuff. Research published in the journal PLoS ONE has found that the mother bears know best when it comes to selecting a place to live. The new University of Alberta study explored whether the rearing of cubs by their mothers shaped which habitats grizzly bears eventually choose. Lead author...

Bears Need All-you-can-eat Salmon Buffet Needed For Months
2012-08-04 05:07:35

redOrbit Staff & Wire Reports - Your Universe Online A mix of steep, colder streams and slower, warmer ones are necessary for both salmon conservation efforts and for bears and other predators that require access to the spawning fish for sustenance, researchers from the University of Washington (UW) claim in a recent research paper. The study, which will be presented during the Ecological Society of America's annual meeting in Portland, Oregon on August 8, shows that managing both...

Cave bear, Ursus spelaeus
2013-06-22 16:42:25

The cave bear (Ursus spelaeus) is an extinct species that was found in Europe during the Pleistocene. Its range was large and included areas from Great Britain to Spain, Italy, Poland, the Balkans, areas of Germany, Russia, the Caucuses, Romania, and northern areas of Iran. Large numbers of skeletons have been found in Switzerland, southern Germany, Austria, northern Spain, Hungary, Croatia, and Romania. Because so many fossils have been found throughout Europe, some experts assert that there...

Kodiak Bear, Ursus arctos middendorffi
2013-06-07 13:18:33

The Kodiak bear (Ursus arctos middendorffi), also known as the American brown bear, the Kodiak brown bear, or the Alaskan grizzly bear, is a subspecies of the brown bear. It can be found in southwestern Alaska, on the islands of the Kodiak Archipelago. Most coastal bears that occur in Alaska are called Kodiak bears, but the true Kodiak bear only inhabits the islands of the Kodiak Archipelago. The Kodiak bear was first described as a distinct species by the taxonomist C.H. Merriam. Merriam...

Grizzly Bear, Ursus arctos horribilis
2013-06-03 13:23:12

The grizzly bear (Ursus arctos horribilis), also known as the grizzly, the North American brown bear, or the silvertip bear, is one of many subspecies of the brown bear. It is typically found in upland areas of western North America. Its range once extended from Canada to Mexico and even into the western shores of the Hudson Bay in the east. Its range has been reduced to many areas of Canada, Alaska, and northwestern areas of the United States including Washington, Wyoming, Idaho, and...

The Asian black bear (Ursus thibetanus), also known as the white-chested bear or the moon bear, is a species that holds a large range. This range includes northern areas of the Indian Subcontinent, most areas of the Himalayas, far eastern Russia, northeastern areas of China, Korea, and the Honshū and Shikoku islands near Japan. As is common to black bear species, the Asiatic black bear prefers a habitat within deciduous forests, mixed forests, deserts, and thornbrush forests. It can...
