Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic, [2] Alpine, [2] and Antarctic.
Consisting of the arctic, alpine, and Antarctic regions, and stemming from the Samer language, tundra literally means a "high and dry place". The arctic tundra has an exceptionally short growing period, minimal sunlight, and limited resources, creating a brutal environment for plants and animals.
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]
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.
An Arctic–alpine taxon is one whose natural distribution includes the Arctic and more southerly mountain ranges, particularly the Alps. [1] The presence of identical or similar taxa in both the tundra of the far north, and high mountain ranges much further south is testament to the similar environmental conditions found in the two locations.
