Gerard LeBlond for redOrbit.com - Your Universe Online The US Geological Survey (USGS) has released a video showing a glimpse into the life of a polar bear. Collar cameras were attached to four female polar bears on the sea ice north of Prudhoe Bay, Alaska in April of this year. The brief footage provides insight into the daily lives of the polar bear. “We deployed two video cameras in 2013, but did not get any footage because the batteries weren’t able to handle the Arctic...

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...

Global Warming Key Topic On This Year's International Polar Bear Day
2014-02-26 06:51:28

[ Watch the Video: International Polar Bear Day ] April Flowers for redOrbit.com - Your Universe Online The annual celebration of International Polar Bear Day is February 27. Polar Bears International (PBI) focuses the attention of the world on the bears, and actions that everyone can take to combat the challenges facing the bears because of global warming. For the second year in a row, PBI is focusing the celebration around a worldwide Thermostat Challenge. The Challenge is one of...

Arctic Biome Under Extreme Threat From A Changing Climate
2014-02-14 10:55:40

Brett Smith for redOrbit.com - Your Universe Online The Arctic as we know it may not exist as climate change is threatening the polar biome’s unique biodiversity and landscape, according to a new report from a large international team of scientists. Conducted by the Conservation of Arctic Flora and Fauna (CAFF) under the Arctic Council, an international forum of Arctic nations, the new study found that climate change could shrink Arctic ecosystems, as advancing changes move north and...

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 Insulation Insights

[ Watch the Video: Looking To Polar Bears For Insulation Tips ] Brett Smith for redOrbit.com - Your Universe Online In work which has major connotations for enhancing the performance of artificial insulation, a team of international researchers has determined hairs and feathers that reflect infrared light might contribute considerable insulating capacity to the remarkably warm winter coats of polar bears and other Arctic animals. Published by the journal Optics Express, the study was...

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...

Medical Legacy Of Knut The Polar Bear
2014-01-03 08:03:07

Leibniz Institute for Zoo and Wildlife Research Keeping wild animals is an important component of the mission of zoos to educate the public and preserve endangered species. When animals die, tracking the potential cause becomes an investigation of pathogens from around the world. This is because zoo animals are not only potentially exposed to pathogens occurring where the zoo is located, but also to those pathogens harbored by other zoo animals. In other words: the diagnostic challenge is...

Climate Scientists Clears Name Settles

Brett Smith for redOrbit.com - Your Universe Online Alaska climate scientist Charles Monnett has settled a lawsuit with the US Department of the Interior over the now famous 'Drowning Polar Bear' controversy. Monnett alleges that the government office was tried to silence him to protect its agenda. Monnet was temporarily suspended in 2011 during an inspector general's inquiry into a polar bear research contract he oversaw while working with what is currently the Bureau of Ocean Energy...

This is the most widely distributed species of bear in the world, although its range is shrinking. Its range includes the Alaska and a few other areas of the United States, areas of Russia, and Romania and other areas of the Carpathian region, as well as Canada, Sweden, Finland, and the Balkans.

Its range includes Northern Armenia, Kopet Dag, Abkhazia, Azerbaijan Talysh, Turkey, Iran, and Iraq. Its range also includes the former Soviet Union. This bear is extinct in Israel, Lebanon, Egypt, and in more recent years it has become extinct in Syria. Due to habitat loss and poaching, the Syrian brown bear population is declining. The bear is also hunted for its bile,...

Syrian Brown Bear

Brown bears as a group are one of the largest type of bears, second only to polar bears with the Syrian brown bear (Ursus arctos syriacus) being one of the smallest subspecies of brown bears.  Found generally in the mountainous areas in the countries of Iran, Iraq and Turkey and in parts of the former Soviet Union to include Abkhazia, Karabakh, Transcaucasia, Talysh and northern Armenia. These bears find hollow birch trees that flourish in the higher elevations, moreso than pine and other...
