Gatherings of thousands of walruses crowded together on northwestern Alaska shorelines, like the congregation of 35,000 animals spotted this weekend near the Inupiat Eskimo village of Point Lay , have become regular occurrences in the new era of scarce summer sea ice.

But the behavior is different from what walruses did in the past, and possibly costly to the big marine mammals, scientists from three federal agencies said at a telephone briefing on Wednesday...

Powerful autumn storms have sent surges of seawater as far as 20 miles inland onto the tundra of southwestern Alaska, and such flooding is expected to become more frequent as the climate changes, according to a study published in the current issue of the journal Arctic ...

With floating ice sparse in the Chukchi Sea, an estimated 35,000 walruses were found crowded onto a beach near the Northwest Alaska village of Point Lay, according to federal biologists.

The congregation of walruses, photographed Saturday by biologists flying over the area in a plane contracted by the National Oceanic and Atmospheric Administration, is one of the biggest onshore gatherings of the animals documented in Northwest Alaska, said one walrus expert.

“It’s a good-sized aggregation, definitely,” said Chadwick Jay , a research ecologist and leader of the U.S. Geological Survey’s Pacific walrus research program ...

Are Alaska Natives, with their ancestors' long history of harvesting and eating healthful wild foods, immune to the ill effects of obesity? Some people erroneously believe they are, no matter how high their body-mass-index readings go, according to one health expert.

"I would say, 'Don't count on it if you continue to eat processed food,'" said Dr. Gary Ferguson, head of wellness and prevention at the Alaska Native Tribal Health Consortium.

The commercial diet that has been fattening up Americans for several generations is quickly making its mark on Alaska Natives and other indigenous people of the north. Rates of obesity have soared, and diabetes -- once virtually unknown among indigenous populations -- is on the rise...

Dangling on branches and scenting the woods in the middle of Alaska’s biggest city are some deep-red nutritional superstars. The tangy, strong-scented high-bush cranberries that grow wild on the Alaska Pacific University campus and across much of the Alaska landscape hold antioxidant loads that are more than seven times those found in commercially cultivated blueberries...

The company promoting the controversial and beleaguered Pebble mine project lost a legal battle Friday when a federal judge threw out one of its lawsuits against the Environmental Protection Agency.

U.S. District Court Judge H. Russel Holland ruled, after listening to brief oral arguments in his Anchorage courtroom, that the Pebble Limited Partnership does not have valid legal basis for its lawsuit seeking to stop the EPA’s deliberations about whether it should block development of large-scale mining in the region...

The U.S. Fish and Wildlife Service will make a decision by the end of next year on whether to give Endangered Species Act protections to wolves dwelling in the coastal rainforest of Southeast Alaska under a legal settlement filed in federal court on Monday.

The settlement would resolve a lawsuit filed in June by conservation groups seeking Endangered Species Act listing for the Alexander Archipelago wolf , an animal the environmentalists say is losing habitat to logging and the construction of logging roads in Tongass National Forest...

Arctic sea ice has started to reform after reaching what appears to be an annual minimum that was the sixth-lowest on satellite record, the National Snow and Ice Data Center said on Monday.

Sea-ice coverage fell to 5.016 million square kilometers (1.94 million square miles) Wednesday, slightly below the minimum reached last year and well below the average recorded from 1981 to 2010, according to the NSIDC. This year’s ice minimum was well above the record minimum of 3.41 million square kilometers in 2012, according to NSIDC data...
