Researchers writing in the open access journal BMC Microbiology found little sign of the microbes in the droppings of polar bears that have had limited or no contact with humans, suggesting that the spread of antibiotic resistance genes seen in other animals may be the result of human influence. Trine Glad, from the University of Tromsø,...

Bears changing habitat in response to sea ice conditions A long-term study showing the changes in habitat associations of polar bears in response to sea ice conditions in the southern Beaufort Sea has implications for polar bear management in Alaska. Karyn Rode, a polar bear biologist with the U.S. Fish and Wildlife Service in Anchorage, Alaska and one of the study's authors, says data collected between 1979 and 2005 show that polar bears in the region are occurring more frequently on land...

There is increased evidence that the Arctic could face seasonally ice-free conditions and much warmer temperatures in the future. Scientists documented evidence that the Arctic Ocean and Nordic Seas were too warm to support summer sea ice during the mid-Pliocene warm period (3.3 to 3 million years ago). This period is characterized by warm temperatures similar to those projected for the end of this century, and is used as an analog to understand future conditions. The U.S. Geological Survey...

President Obama designated more than 200,000 square miles in Alaska and off its coast as "critical habitat" for polar bears on Thursday, an action that could add restrictions to future offshore drilling for oil and gas, The Associated Press reported. Under federal law, agencies are restricted from taking actions that may adversely affect critical habitat and interfere with polar bear recovery. "It is a step in the right direction to help polar bears stave off extinction, while recognizing...

The U.S. National Oceanic and Atmospheric Administration (NOAA) has just three weeks to decide whether spotted seals, which rely upon sea ice off the coast of Alaska, should be classified as a threatened or endangered species. The agency also agreed to decide no later than Nov. 1, 2010, whether ringed seals and bearded seals, both ice-dependent seals, should be listed. The settlement between NOAA and the Center for Biological Diversity, which had sued to force a decision, was approved on...
