This could point to potential climate or food shortage stressors affecting the feeding behaviors of the House Sparrows.

On Friday, it was measured 12.8 degrees C in Folldal, over 30 degrees warmer than on the same day last year.

The reindeer owners feel they had to choose. Pay expensive fines or move with the reindeer across the river even if the ice was too thin. On Saturday, a thousand reindeer went through the ice in Vuorašjávri, a mile east of Kautokeino municipality in Finnmark.

In the pictures, Måøya looks like a pristine natural gem on the coast of Trøndelag. But when scientists and adolescents started digging into the soil, they got shock.

The Yukon First Nations Education Directorate gave away 30,000 pounds of free fish as part of its nutritional program in Whitehorse this week. People were particularly happy to receive the donation because salmon are well below the historical average this year.

About 189,000 fall chum had entered the Yukon River as of Sept. 7. At least 300,000 fish must enter the river before either Alaska or Yukon fishers can begin harvesting.

Palsmyr is threatened by climate change. At Ferdesmyra in Finnmark, the characteristic ice-filled pals that protrude from the terrain will be gone in a few years.

After a decade of heavy erosion, a lake in the Bristol Bay village of Port Heiden finally breached, sending water gushing into the bay.

Thawing sea ice may have opened the door, allowing the infection to cross oceans, a new study suggests.

Aerial surveys this September and October show the bowheads aren’t where they usually are.

Gradual sea ice reduction and reconfiguration of the coast, have increased the rate of erosion near Port Heiden over the course of several decades. Draining of Goldfish Lake brings memories, loss of community landmark, and many emotions.

This year was one of the warmest and wettest in recorded history and permafrost thaw is causing the ground at the community cemetary to thaw and erode. The community is seeking guidance on best practices for relocation of remains.

This stoop-pumpkin-rotting event is unusual compared with Dr. Johnson's long-term (lifetime) time series of annual October observations of stoop pumpkins in New York City.

Nils Thomas discovered "sinkhole" in the middle of Finnmarksvidda. Scientists have long warned against this, and now it happened.

Instead of halibut, fisherman are increasingly catching less valuable Pacific cod, voracious bottom feeders whose numbers in recent years have exploded.

The number of chinook salmon that reached the Whitehorse fish ladder this year hit a 40-year low, and it's not clear why. Just 282 chinook passed through the fish ladder this year, compared to 690 last year. "We did see some large pre-spawn mortality die-offs in a tributary of the Yukon River — the Koyukuk in Alaska. This was for summer chum, and not chinook — but we expect that that higher water temperature also affected the chinook migrating through."

While there is no risk to human health, the species of moth can decimate forests

Thousands of smelts were found dead during low tide in the Togiak slough. Is there an environmental cause?

Anglers in Aklavik, N.W.T., are trying to figure out why there was a shortage of fish in local hotspots this year.
