UAS professor Eran Hood is part of a team of scientists who found that the retreat of glaciers in Alaska and British Columbia’s coastal temperate rainforest could produce more than 3,800 miles of potential new Pacific salmon habitat by the year 2100. A new study in the journal Nature Climate Change, lead by researchers at […]
March 31, 2021 (Juneau, AK) – Alaska’s Congressional Delegation issued the following statements in support of Governor Mike Dunleavy’s move to exert control over Alaska lands and waters. “I know Alaskans to be responsible stewards of our precious environment, which is why Alaska is correct to assert management over navigable waterways,” said Congressman Don Young. […]
Right now, on the brushy tundra of northern Alaska, grizzly bears are gathering at quiet streams and rivers, attracted by the largest calorie reward they can find — spawning salmon. Until recently, scientists did not know salmon swam up some of these waterways, nor that grizzlies were fattening up on them before entering hibernation. […]
A new federal report says that Alaska’s rainforests contribute an average of 48 million salmon annually to the state’s commercial fishing industry. The study led by the US Forest Service’s Pacific Northwest Research Station found that the average value of these “forest fish” when they are brought back to the dock is some $88 […]
University of Alaska Fairbanks scientists are developing a new method to predict ecosystem change in Interior Alaska, and their techniques could prove useful elsewhere in the world. The study uses real-time water data, rather than simulations, to predict ecosystem “tipping points.” “We’re pretty good, as ecosystem ecologists, at using stream chemistry to tell us […]
Sen. Lisa Murkowski, R-Alaska says a mine that can’t stand on its own without negative impact to fisheries resources should not be permitted. Murkowski’s concerns, addressed during a Washington DC celebration of Bristol Bay’s wild salmon, came in the wake of her reading the draft environmental impact statement for the proposed Pebble mine produced by […]
Adult sockeye salmon returning to spawn in the lakes of Bristol Bay, Alaska.Jason Ching/University of Washington An ample buffet of freshwater food, brought on by climate change, is altering the life history of one of the world’s most important salmon species. Sockeye salmon in Alaska’s Bristol Bay region are skipping an entire year […]
Photo: A spawning sockeye salmon.Jason Ching/University of Washington Chemical signatures imprinted on tiny stones that form inside the ears of fish show that two of Alaska’s most productive salmon populations, and the fisheries they support, depend on the entire watershed. Sockeye and Chinook salmon born in the Nushagak River and its network of streams and […]
A volcano is like a stream. It might sound like a Zen proverb, but it’s a useful comparison for University of Alaska Fairbanks Geophysical Institute graduate student Julia Gestrich. Scientists can use stream flow to understand volcano ash plumes, Gestrich explained while presenting her research at the American Geophysical Union Fall Meeting in Washington, D.C., […]
