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.

Rising temperatures and dwindling oxygen levels are decimating marine species. But humanity can avert mass die-offs by curbing fossil fuel use and other planet-warming activities.

Trees purify the air and generate economic benefits, but unbridled development in cities is increasingly changing growing environments

Forty-two reindeer were found foraging among the skeletal remains of a herd on St. Matthew’s Island, a remote patch of Alaskan land in the Bering Sea. What makes it most puzzling is that only three years earlier, the same herd numbered 6,000 animals.

White-nose syndrome has wiped out millions of bats in North America, pushing researchers to look at alternative roosts like bat boxes. But the U.S. bat box designs may not suit Canadian bats.

When it comes to avian influenza, more commonly known as bird flu, all birds are not created equal.

Researchers say warmer waters themselves aren’t killing crabs, but they may be allowing predators to move in and disease to spread more easily.

Researchers at Oregon State University are studying the relationship between sunflower sea stars and sea urchins to determine if the reintroduction of the sea stars can help protect declining kelp forests from overgrazing by sea urchins.

The Alaska Department of Fish and Game announced it was closing the 2023-24 Bering Sea snow crab season for the second season in a row.

Widespread mortality of Pacific salmon Oncorhynchus spp. returning to spawn in Alaska coincided with record-breaking air temperatures and prolonged drought in summer 2019.

Deprived of once plentiful seagrass, more than 900 have died this year. Some experts contend they were taken off the endangered species list prematurely.

Salmon runs in Alaska's Kuskokwim River show some improvement compared to last year, but overall numbers remain low, with chum and coho salmon still below long-term averages, while Chinook salmon meet escapement goals through precautionary management and sacrifices by subsistence users.

Canada’s Western Hudson Bay polar bear population has fallen 27 percent in just five years, according to a government report released last week, suggesting climate change is impacting the animals.

The clam population crashed on the east side of Cook Inlet about a decade ago and has been slow to bounce back.

Berry pickers have long reported that the number of wild berries has been diminishing, and a 26-year study is now confirming the unexplained decline.

The number of gray whales migrating along the Pacific Coast of North America has steadily declined by nearly 40 percent from a 2016 peak, and the population produced its fewest calves on record this year, according to U.S. research released on Friday.

Two resolutions brought before the Alaska Federation of Natives during this year’s annual convention called for efforts to reduce salmon bycatch for fish that return to the Yukon and Kuskokwim rivers.

A year after the closure of the Bering Sea crab harvests in Alaska, surveys show that crab populations are still low, raising doubts about future harvest prospects and suggesting that continued closures may be necessary.
