As Alaskan permafrost warms, hibernating arctic ground squirrels generate less heat, causing females to emerge from hibernation up to 10 days before their male counterparts – a mismatch that could have large, cascading ecological impacts. While reduced thermogenesis due to warming temperatures could allow the squirrels to conserve energy and, thus, increase winter survival, a shortened hibernation season could also increase the exposure of the animals to hungry predators, altering mortality rates, particularly for earlier emerging female squirrels. The phenological mismatch between the sexes may also disrupt reproductive rates. And over longer time scales, continued warming in the Arctic may lead to changes in male squirrel seasonal behaviors, say the authors.
Homer police confirmed the Wednesday capture of the “wanted fugitive and somewhat local celebrity," otherwise known as an invasive species.
The U.S. Fish and Wildlife Service Office of Subsistence Management held the second public hearing on May 2 about the proposal to reduce the caribou harvest limit for resident hunters across the range of the Western Arctic Caribou Herd from five caribou per day to four caribou per year, only one of which may be a cow.
Arctic Foxes are curious animals of the North and often will befriend humans and not be afraid. Often times they move into other fox areas and territory.
State officials say Alaskans who encounter bats should avoid any physical contact. The state's last rabid bat was found last June near Juneau.
Of the 61 red foxes counted in and around Nome between February and March 2023, nearly one quarter were positive.
With geese and other wild birds returning to the region every day, New Brunswick dog and cat owners should be aware of the risk of avian influenza, says the registrar of the New Brunswick Veterinary Medical Association.
Ambler Elder Virginia Commack said that the borough's decision does not reflect the opinion of many Northwest Arctic residents. This month, almost 80 Northwest Arctic residents, current and former, signed the petition against the development of the Ambler road project. When the Alaska Department of Natural Resources held two public hearings last year, out of about 37 people who called, only two spoke in support of the project.
Many hikers in Southern Alberta head to the trails in spring equipped with bear spray, singing or saying hey bear, woah bear, to warn the animal they're around the corner. Elders and knowledge keepers from Stoney Nakoda Nations have their own approach, and lessons to share when it comes to co-existence.
The musk oxen attract a lot of tourists, and generate a lot of traffic into reindeer areas.
The big animals that roam Alaska’s largest city are carrying bacteria that cannot be killed by commonly used medicines.
At the world’s northernmost year-round research station, scientists are racing to understand how the fastest-warming place on Earth is changing — and what those changes may mean for the planet’s future.
Arctic species are currently under multiple pressures and several are red-listed. Adaptive ecosystem-based monitoring and management applied to the critically endangered arctic fox in Finnmark, illustrates how such pressures can be uncovered and potentially mitigated.
Researchers will be stepping up their efforts to track chronic wasting disease in Saskatchewan's north.
The Copper River Basin in Alaska has experienced less reliable snow and ice conditions in recent years, impacting winter activities such as trapping, hunting, and gathering firewood. This study, based on nine oral interviews with local residents, reveals that crossing rivers has become more treacherous and difficult, with significant changes in ice conditions observed since the 1970s. Decreased snowpacks and increased shrub growth have also posed obstacles for accessing winter trails, requiring individuals to cut through forests. These changes, combined with socio-economic and technological factors, have affected the way people engage in winter activities in the Copper River Basin. Overall, this research contributes to the understanding of climate change's impact on winter activities in Alaska and the Circumpolar North.
The government of Nunavut has once again flipped its position on resource development on caribou calving grounds, now supporting a "prohibition of development within calving grounds and key access corridors, with seasonal restrictions on activities in post-calving grounds."
Questions still linger about what caused the bear to kill a woman and her baby — but more important for Wales is the question of how to move on.
A video of the reindeer on the steps of the wind turbine has caused wonder. Aren't the animals intimidated by wind power anyway? Here are some reasons why it is so difficult to find clear facts and secure figures.
A new variant of bird flu has recently infected both sea lions and mink. Health authorities around the world are now monitoring that it does not begin to infect humans.
Another species of deer has been detected suffering from chronic wasting disease in Manitoba according to the province.
