Beavers are transforming Alaska's Arctic tundra, creating both challenges for local communities and ecological opportunities, as their population and dam-building activities alter landscapes and affect permafrost.
A minimum of 42,500 chinook are supposed to get to their Canadian spawning waters to meet conservation goals. Only 15,300 of those fish made it to Eagle, near the Yukon border.
Researchers say climate change is playing a big role in the collapse, which has left thousands of people along the river without the salmon they depend on.
Chinook (king) and chum are the major salmon species on the Yukon and Kuskokwim. They’ve been at historically low numbers in both rivers for years. The coho (silver) returns have also dropped.This will be the fourth year subsistence fishing has been closed or severely restricted on both rivers. The region is bracing for another dismal subsistence harvest.
Alaska researchers will continue a controversial study this year on a parasite in Yukon River chinook salmon that requires killing hundreds of fish, a move that’s drawn sharp criticism from Canadian experts.
Yukon River chinook salmon runs have been steadily declining, with 2022 the smallest run on record. As the fish disappear, Yukon First Nations fear the cultures and traditions built around the salmon over countless generations will too.
The warming climate in Alaska and across the circumpolar North is creating new health and safety risks for people, animals and ecosystems. This piece is the part of a series that explores zoonotic diseases and other hazards emerging in a warming and thawing Alaska. One warm June day, Joey Ausel found an odd speck
Vancouver Island’s arbutus trees are looking more brown than green these days. Forest biologist Andy MacKinnon says a fungus is attacking the trees, causing the leaves to die off.
A new report based on necropsies conducted by the USGS's National Wildlife Health Center in Wisconsin suggests that the die-off was caused by long-term starvation and was likely exacerbated by a spate of freakishly cold weather.
Researchers have identified an invasive blood-sucking parasite on mud shrimp in the waters of British Columbia's Calvert Island. The discovery represents the northern-most record of the parasite on the West Coast and is likely an indication of its ability to spread without human transport.
Wild salmon have higher rates of the parasites when ocean fish farms are near, research shows
University of Rhode Island student stumbled upon the first appearance in Rhode Island of what has come to be called sea potatoes (Colpomenia peregrina), an invasive seaweed native to the coast of Korea and Japan that grows on top of other seaweeds.
The aquaculture industry has failed to bring epidemic of sea lice under control in B.C.’s Clayoquot Sound.
Dead salmon have shown up in river systems throughout Alaska, and the mortalities are probably connected to warm water or low river water levels, said a Fish and Game official.
According to the Canadian Association of Professional Apiculturists, the most frequently cited causes of bee mortality were weather, starvation, poor queens and weak colonies in the fall.
Alaska hunters will discover a new page in the 2019-2020 hunting regulations which describes mule deer and white-tailed deer, two historically non-native species that are now moving into Alaska.
DFO documents reveal treatment failures and inability to protect migrating salmon.
CONCORD, N.H. (AP) — More than a dozen wild bee species critical to pollinating everything from blueberries to apples in New England are on the decline, according to a new study. Researchers...
Researchers are using data from the “Submit-a-Tick” program to model where non-native ticks might thrive in future decades as climate conditions change.
Warming ocean waters are an invitation to all sorts of pathogens with the potential to remake ocean life.
