Study finds genetic evidence of climate-change adaptation.
Warming of Alaska has dire consequences for state; effects of 7-degree rise in Alaska's temperature over last 30 years include buckling highways, shoreline erosion and forests killed by beatles; in Alaska, rising temperatures, whether caused by greenhouse gas emissions or nature in prolonged mood swing, are not a topic of debate or an abstraction; Sen Ted Stevens says that no place is experiencing more startling change from rising temperatures than Alaska and that problems will cost Alaska hundreds of millions of dollars; photos (M)
A grassroots project to build biomass-heated greenhouses aims to alleviate food insecurity in the communities most affected by it.
Demonstration of how easy ponderosa pine tree tops can be broken due to the effects of climate change.
"We never know for sure how they died, but it does seem like a lot of the evidence points to killer whale predation," Steve Ferguson, a research scientist with Fisheries and Oceans Canada, said Thursday.
A total of 80 stockfish fillets of Northeast Arctic cod (Gadus morhua), traditionally open-air-dried in northern Norway, was examined for the presence and viability of larval parasitic nematodes of the family Anisakidae. Anisakids (particularly those belonging to genera Anisakis and Pseudoterranova) are of public health and economic concern globally, since they are responsible for an underestimated fish-borne zoonotic disease called anisakidosis.
The article reports on a successful emergency response drill in Chukotka, Russia, where a simulated bird flu outbreak was contained.
Worms infecting fish grow four times faster at higher temperatures and manipulate the behavior of fish.
Authorities try to talk down a wave of panic buying in B.C. stores as washed-out roads and rail lines snarl supply chains
The Little Salmon Carmacks First Nation is warning spring melt could cause the tailings dam at the abandoned Mount Nansen mine in central Yukon to overflow or breach, which would send a toxic slurry into the environment.
Scientists looking at salmon found in Arctic waters are still asking northern harvesters and fishers to submit any unusual catches in exchange for compensation. It's part of the Arctic Salmon Project, which is a collaborative effort involving Fisheries and Oceans Canada, scientists from the South and local hunters and trappers organizations.
The Inuit are famous for their ability to survive extreme conditions, having inhabited the Arctic for millennia. But as the ice recedes, this hard-earned knowledge is being lost.
There were no bugs buzzing around the lights in the parking lot.
The need to diversify America's sources of graphite for electric vehicle batteries is driving the exploration of graphite mining projects in the United States, but concerns about the potential environmental impact and disruption to Indigenous communities remain.
Researchers looked inside the stomachs of 34 spotted seals that were collected in Gambell and Shishmaref in 2012 and 2020. Of those, 33 contained microplastics.
“Our results suggest that warming is both increasing freshwater habitat and improving early marine survival of pink salmon in the northern Bering Sea,” said Ed Farley, NOAA Fisheries biologist at the Alaska Fisheries Science Center, who led the study.
Most of Alaska sits atop permafrost. But the ground is thawing, leading to unexpected and sometimes catastrophic outcomes — what scientists have called a “slow disaster.”
An aerial survey of the moose population in Zone 17 and the southern part of Zone 22 carried out in 2021, shows a 35 per cent decline in moose populations, a moderate and concerning decline, says Cree Grand Chief Mandy Gull-Masty.
“While many factors, such as weather, climate change and changes to the historical extent and timing of caribou migration may be contributing to lower harvests by federally qualified subsistence users, the board should act to help ensure that rural residents are able to meet their subsistence need, and to provide for a subsistence priority,” said Thomas Heinlein, acting Alaska director for the Bureau of Land Management, during the board meeting.
