The arctic tundra has an exceptionally short growing period, minimal sunlight, and limited resources, creating a brutal environment for plants and animals. By adapting to these harsh conditions, animals and plants represent iconic characteristics of the tundra.
The Arctic tundra, a critical “carbon sink” for thousands of years, is now releasing more of the greenhouse gas than it takes in, scientists have announced. Carbon sinks like the Arctic play ...
The Arctic coastal tundra is an ecoregion of the far north of North America, an important breeding ground for a great deal of wildlife. Setting
The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...
A focus of the latest Arctic evaluation was the effects of warmer weather and wildfires on the tundra, a far-northern biome that's typically known for extreme cold, little precipitation and a ...
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
