The otter population in Sweden is bouncing back after having been severely hit by hunting, road accidents and toxins in the environment in past decades.Since ...

A snowstorm in Southcentral Alaska causes power outages and leads to the cancellation of a Veterans Day ceremony, while crews work to clear roads and restore electricity.

Wildlife surveys in southwest Yukon have shown a 'concerning' decline in the number of Dall sheep — and biologists say recent snowy winters may be to blame.

Hunters are concerned about the small and lean size of moose calves, which may be due to various factors such as climate, dry weather, and late-born calves, leading to potential consequences for the moose population.

The EPA plans to limit or eliminate a chemical commonly used in car tires, known as 6PPD, after it was found to be fatal to salmon in preliminary Alaska sampling, in response to a petition from Native Tribes and several states, but the rulemaking process is expected to take years.

Over 5,000 Peruvian sea lions, approximately 5% of Peru's population, succumbed to a mass mortality event linked to the avian influenza A(H5N1) virus, signaling an urgent need for research and conservation efforts to prevent further declines. The rapid spread of the virus among these colonially breeding mammals highlights potential risks of cross-species transmission and the necessity for heightened monitoring to avert new pandemics.

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.

Geneviève Degré-Timmons, a PhD candidate, is studying why caribou use burned lands and when they stop using them, and has created a painting to represent the cycle of the boreal forest and caribou interactions within it.

The increase in pink salmon population in warmer waters is negatively impacting the food chain and causing a decline in other species in the North Pacific Ocean, according to a new study.

The Okanagan Basin Water Board is proposing a temporary ban on out-of-province boats entering British Columbia's waterways to prevent the introduction of invasive mussels that could cause significant harm to the ecosystem and cost the province millions of dollars annually.

The Kenai borough Assembly has passed a resolution asking the governor to declare an economic disaster for set-netters on the east side of Cook Inlet in Alaska, due to the closure of the fishery this year resulting in significant economic losses.

A new AI radar system called "Bear-dar" has been developed to detect polar bears remotely and send alerts to notify people of their presence, and could potentially be used to detect grizzly and black bears as well, helping humans and bears coexist safely.

Extreme flooding on Alaska's Arctic highway in 2015 caused thaw-induced sinking in the permafrost terrain up to 3 inches deep, with the most significant effects occurring in ice-rich areas, according to a newly published study.

Toxicological studies spotlight the effects of pollutants on polar bears and whales, with new research strategies being developed to understand their impact on marine life.

Algal blooms in the Liffey River threaten Dublin's drinking water due to pollution and climate change, raising concerns about the safety of fish and the future impact on water treatment.

The Western Arctic Caribou Herd in Alaska has continued to decline, with a 7% decrease in population from the previous year, prompting concerns about the need for harvest reduction to preserve the herd.

A new atlas exploring permafrost in the Arctic aims to provide a comprehensive understanding of the changes occurring in the region, featuring maps, illustrations, photographs, artwork, and testimonials from Arctic residents and scientists.

A UK study has found that some species of seabirds are developing immunity to avian influenza, which has caused significant mortalities in wild bird populations and poses a threat to human health.

Nipissing First Nation in Ontario, Canada is using innovative methods, such as aerating water and replacing invasive species with wild rice, to heal environmental damage and improve the ecosystem.

If puffin hunting is banned, that population is expected to decrease by over 10% over the next decade. If hunting continues to be permitted, however, the population is expected to decrease by 30% or even as much as 50% within that same period.
