A study led by the UAB and the CREAF shows that the loss of nitrogen from Arctic soil not only deprives plants of a vital ...

Subarctic ecosystems store large amounts of carbon. As the climate continues to warm, more and more carbon is being released into the atmosphere. There are large uncertainties concerning the ...

Long before the sea was named for the 18th century Danish cartographer and Russian naval explorer Vitus Jonassen Bering, the icy water body consisted of two distinct ecosystems — one subarctic ...

A Shifting Balance Alaska’s remote Aleutian Islands have always been an oasis for marine life. But this subarctic ocean ecosystem has undergone a dramatic transformation in recent years.

We simulated the future climate and traced CO2 from the atmosphere into the subarctic ecosystem," says the first author of the study, Dr. Andrea Ghirardo, from the phytotron facility in Munich.

But as subarctic temperatures rise, this vital ecosystem is losing stability with swelling fire activity, thawing permafrost and insect infestations.

A sub-arctic ecosystem off Southeast Greenland dominated by large amounts of drifting pack ice has changed during this century to a more temperate system with less sea ice and warmer ocean ...

“This is unprecedented in the United States for a mature, rationalized fishery to suffer a stock collapse, in part due to climate change,” the executive director of the Alaska Bering Sea ...

Mosses in subarctic tundra are colonized by bacteria that fix atmospheric nitrogen (N 2), and together, they can contribute 50% to total ecosystem N input. Despite this key role, the effects of ...
