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...

Climate Woes Continue: Changes In Polar Bear Diet Result In Higher Toxin Exposure
2013-09-20 12:34:08

Brett Smith for redOrbit.com - Your Universe Online Warmer than average Arctic temperatures in recent years have been stirring up all kinds of ecological changes and a new study in the journal Global Change Biology indicates that polar bears could be getting exposed to higher levels of toxins as a result. The study looked at an East Greenlandic population of polar bears, which is expected to enjoy the Arctic sea ice far longer than other regions. However, the loss of ice sheet cover in...

A new paper co-written by UM associate professor Mark Hebblewhite details ecological changes caused by a loss of Arctic sea ice. The paper concludes that the loss of sea ice obviously will impact the marine food web and the marine mammals that depend on sea ice habitat. Other major ecological changes in adjacent land-based habitats and species also will occur because of warming oceans. The findings were published in the Aug. 2 issue of Science magazine. Wildlife species like the polar...

Wildlife Greatly Impacted By Arctic Sea-Ice Loss
2013-08-02 07:11:40

April Flowers for redOrbit.com - Your Universe Online Because sea ice is at its lowest point in 1,500 years, scientists are questioning how ecological communities in the Arctic will be affected by this continued and perhaps accelerating melting process over the next two decades. An international team of scientists, led by Penn State University biologist Eric Post, examined relationships among algae, plankton, whales, and terrestrial animals such as caribou, arctic foxes, and walrus, as...

PFS Toxins Found In Polar Bear Brain Tissues
2013-07-23 17:47:09

Susan Bowen for redorbit.com - Your Universe Online As if polar bears didn't have enough problems, researchers have found Perflouroalkyl substances (PFS's) in their brains. Scientists are becoming increasingly aware of the toxicity of these compounds. They can cause gene mutations and cancers. They can also affect reproduction and development, in addition to being toxic to the nervous system, the endocrine system and the immune system. These compounds are extremely persistent in nature...

Black Bears Return To Missouri
2013-07-20 04:57:31

April Flowers for redOrbit.com - Your Universe Online By the 1920s, unregulated hunting and habitat loss had wiped out the majority of black bears, Ursus americanus, in Arkansas, Missouri and Oklahoma. The only bears known to live in Missouri for nearly a century were on the state flag, or in captivity. A reintroduction program, conducted during the 50s and 60s in Arkansas, has created a resurgence of bears. Now hundreds amble through the forests of southern Missouri, according to a...
