There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...
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 ]
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 tundra has historically helped reduce global emissions. But rising temperatures and wildfires in the region are changing that, scientists say. Arctic tundra becoming a source of carbon ...
There are various bird species that have been spotted in the Arctic. Eight species of birds reside on the polar tundra year round while 150 breed in the Arctic. [16] The birds that do breed go to the Arctic between May and July. One of the known birds is the snowy owl, which has enough fat on it to be able to survive in the cold temperatures.
The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
The Arctic experienced its second-hottest year on record, according to a NOAA report. The Arctic tundra has become a source of emissions, rather than a carbon sink.
