Both plant species and animal species have become endangered. The Aleutian shield fern is a plant species that have been endangered due to caribou tramping and grazing, slumping from growing substrate, and human foot traffic. [9] Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears.
The biodiversity of tundra is low: 1,700 species of vascular plants and only 48 species of land mammals can be found, although millions of birds migrate there each year for the marshes. [9] There are also a few fish species. There are few species with large populations.
The species within boreal ecosystems varies as it consists of both terrestrial and aquatic habitats. The species composition include many generalized and less specialized feeders. [4] From the equator to the poles, species richness decreases, and there is a negative relationship with species richness changes as climate changes. [5] [4]
The area is one of the "most productive" [5] in the United States for petroleum extraction including a 9 million hectare area reserved for this activity. [6] As Arctic seas warm and ice recedes, it is believed that these areas contained within the Arctic coastal tundra may reveal some of the largest petroleum reserves in the world. [7] [8] [9]
A variety of animal species are distributed across continents, throughout much of the Holarctic realm. These include the brown bear, grey wolf, red fox, wolverine, moose, caribou, golden eagle and common raven. The brown bear (Ursus arctos) is found in mountainous and semi-open areas distributed throughout the Holarctic.
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 ...
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 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 ...
