A new report reveals a rise in polar bears on land and dangerous travel conditions in Northwest Alaska due to climate change.

The report reveals an unusual increase in polar bear presence on land in Northwest Alaska due to declining sea ice, posing challenges for human-bear interactions and travel safety, while warming temperatures and shifting seasons complicate traditional travel and hunting practices.

The H5N1 bird flu virus has recently been detected in Alaskan wildlife, primarily affecting species like geese, ducks, and eagles. No human cases have been reported, but it poses a significant risk to domestic poultry flocks.

The South-central Invasive Species Strike Team is actively working in Bristol Bay to manage and control the spread of invasive species, such as Bird Vetch, which threaten local ecosystems essential for subsistence in Alaska.

Unusually large amounts of sea ice have brought more polar bears from Northeast to South Greenland, with many unable to return due to currents.

The unusually hot summer weather in the Moscow region this year may trigger an increase in populations of invertebrate species, the regional Environmental Ministry said this week.

ADF&G has confirmed the spread of the invasive European green crab in Alaska, urging increased monitoring and public awareness to mitigate its destructive impact on local ecosystems.

A potential rat sighting on St. Paul Island, which has maintained a rat-free status for over two decades, prompts urgent conservation efforts to protect local seabirds and wildlife.

An increase in chum salmon in the Canadian Arctic, potentially linked to climate change, may be the same fish missing from Western Alaska, raising ecological concerns.

Sea ice loss, warming waters and the northward expansion of fish species like pollock are all contributing to a pattern in the Bering Strait region known as “borealization.” That means the Arctic ecosystem is becoming more like the boreal region to the south.

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.
