A wildlife biologist says the search isn’t over. Opossum litters are usually eight or nine joeys — and can be as many as 13.

Norway should dismantle two large wind farms that were stripped of their licenses for jeopardizing traditional reindeer husbandry, herders from the Indigenous Sámi community said on Friday. Reindeer herders say the sight and sound of giant wind turbines frighten their animals and thus disrupt age-old traditions.

Authorities are searching for a brown bear near the village of Provideniya in Chukotka, Russia. The bear has been sighted near the village, prompting concerns for the safety of the local residents.

Arctic fox rabies is enzootic in populations of arctic and red fox populations along Alaska’s northern and western coasts. This means rabies is always present in these populations at some low level but periodically there can be outbreaks called epizootics (an outbreak in animal disease rather than an epidemic as is it is called when occurring in a human population). However, the winter of 2020-2021 ushered in a widespread outbreak with persistent and large focus in and around Nome.

Biologists are collecting samples from moose and mustelids — that’s wolverines, minks and martens. There are plans to test caribou and Sitka black tail deer, as well as seals and belugas.

Biologists want to know why there are so many moose. It may have a lot to do with shrubs — moose feast on their leaves during the spring and summer. These short woody plants are spreading west, aided by climate change, and moose populations are expanding along with them.

CWD was first recorded in Saskatchewan in 1996 on a game farm, but has since moved into the wild deer, elk and moose populations, with wildfire-like infection rates in some areas. Up to 70 per cent of male deer are infected with the fatal disease, says a wildlife health specialist.

Beavers, on the other hand, leave a mark on the landscape that you can sometimes see from space.Swarming ponds, building dams and expanding waterways, beavers are moving farther and farther into the Arctic, and are changing what the region looks like.

Arctic biologists use 25 years of data to find that warmer autumns might be enough to increase the odds of reindeer’s winter survival on Svalbard.

Arctic fox rabies is enzootic in populations of arctic and red fox populations along Alaska’s northern and western coasts.

For years, populations of Sitka black-tail deer have slumped, leaving residents without a staple source of protein. A three-day summit held in Craig last month prompted lengthy discussions about the problem. When loggers cut down a section of old growth Sitka spruce, hemlock and cedar in the Tongass National Forest, there’s no need to replant — trees grow back on their own. It’s what scientists call an “even-aged forest.” When trees all start growing at the same time, they create a dense canopy that prevents light from reaching the ferns and berry bushes that black-tail deer love to snack on. And because the trees grow close together, they end up long and spindly — not the massive, thick, tight-grained trunks that make old growth lumber so highly valued.

The disease and virus likely exist well beyond the state’s borders, making the new name more scientifically accurate, officials say.

Ida Wessman, 28, bought her family's herd of reindeer after her father passed away five years ago. "It's been going pretty well. With this industry you've got high points and low points," Wessman said, alluding to severe 2019-2020 weather that killed 15,000 of the animals.

Fall moose hunts are beginning across Alaska. In western parts of the state, biologists hope that hunting pressure will help protect the health of booming populations. They also want to know why there are so many moose in the first place. It may have a lot to do with shrubs — particularly scrubby willows shooting up at the edges of open tundra. Moose feast on their leaves during the spring and summer. These short woody plants are spreading west, aided by climate change, and moose populations are expanding along with them.

Residents and Fish and Game present ideas and opinions around Northwest Caribou population and hunting regulations and restrictions. .

Researchers have developed a non-invasive method to monitor polar bear and lynx populations by extracting environmental DNA from their paw prints in the snow, offering a safer and potentially more informative alternative to traditional tracking methods.

A proposal to relocate Sitka black-tailed deer into areas crisscrossed with roads, farms and established wildlife populations may ultimately cause more problems than it’s worth, says an internal report from the Alaska Department of Fish and Game.

An incurable disease found in deer, elk, and moose is spreading across Alberta, according to new provincial surveillance results — and certain populations have reached a 23 per cent positivity rate. 

The small Swedish town of Fagersta, Västmanland County, has been at the epicentre of the recent outbreak of African swine fever.All activities in an area of forest around 1000 square kilometers in the counties of Västmanland and Dalarna have been off limits since Friday following the discovery of dead wild boar.
