JUNEAU, Alaska—Alaska’s population decreased by 2,629 people—about one-third of 1 percent—from July 2016 to July 2017, based on population estimates released today by the Alaska Department of Labor and Workforce Development. Net migration—in-migration minus out-migration—accounted for a loss of 8,885 people while natural increase, or births minus deaths, added 6,256 people. This was the fifth […]
Genetic analysis of ancient DNA from a 6-week-old infant found at an Interior Alaska archaeological site has revealed a previously unknown population of ancient people in North America. The findings, published in the Jan. 3 edition of the journal Nature, represent a major shift in scientists’ theories about how humans populated North America. The researchers have […]
It’s no secret that human activities affect fish, particularly those that must migrate to reproduce. Years of building dams and polluting rivers in some regions have left fish such as salmon struggling to return to their home streams and give birth to the next generation. A new University of Washington study points to yet another […]
It’s one of the most contentious debates in anthropology today: Where did America’s first peoples come from — and when? The general scientific consensus is that a single wave of people crossed a long-vanished land bridge from Siberia into Alaska around 13,000 years ago. But some Native Americans are irked by the theory, which they […]
With dogs’ breath fogging the 30-below zero air at their knees, 71 Iditarod mushers steamed their way down the frozen Chena River in Fairbanks on March 6. Upstream, just a few miles behind them, 500 ducks were surviving in a one-mile stretch of open water. You might think the mallards that did not migrate […]
The annual migration of some beluga whales in Alaska is altered by sea ice changes in the Arctic, while other belugas do not appear to be affected. A new study led by the University of Washington finds that as Arctic sea ice takes longer to freeze up each fall due to climate change, one […]
Biologist Susan Sharbaugh, formerly of the Alaska Bird Observatory, once spoke about the strategies birds employ to survive in our season of darkness and cold. She talked about the flighty birds that split, and the hardy few that stay. I thought I knew something about birds, but she kept delivering facts that were new to […]
Right now, young Chinook salmon are leaving the rivers they were born in to begin life at sea. The first year in the ocean is thought to be the most critical time in the life of a salmon, and largely decides how many will live and be available to harvest as adults or return to […]
The upper Colville River is one of the quietest places on the planet, a land of cliffs and tundra and tangles of willow. Fashion Island is one of the most human-altered landscapes in America, where developers long ago replaced the native vegetation with a Cheesecake Factory and P.F. Chang’s. A female peregrine falcon born in […]
