The other type is the lichen woodland or sparse taiga, with trees that are farther-spaced and lichen groundcover; the latter is common in the northernmost taiga. [32] In the northernmost taiga, the forest cover is not only more sparse, but often stunted in growth form; moreover, ice-pruned , asymmetric black spruce (in North America) are often ...
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 taiga is inhabited by many species, some of which are endangered, and include the Canadian lynx, gray wolf, and grizzly bear. The Canadian lynx is one well-known animal to inhabit the North American taiga region and is listed as threatened in the U.S. The mother lynx will have a litter of about 4 kittens in the spring.
The milk production of a moose is small compared to a dairy cow: over the lactation season, a total of 300–500 liters (75–125 gallons) of milk is obtained from a moose. However, the milk has a high (12–14%) fat content, and is rich in vitamins and micronutrient elements; it is said to have medicinal properties.
Alaska moose are sexually dimorphic with males being 40% heavier than females. [5] Male Alaska moose can stand over 2.1 m (6.9 ft) at the shoulder, and weigh over 635 kg (1,400 lb). When Alaska moose are born, they weigh on average about 28 pounds, but by five months old they can weigh up to 280 pounds. [4]
There is little food for animals to eat in the Arctic. Reindeer utilize their powerful hooves and antlers to sift through snow and ice and eat foods such as: Grasses. Bushes. Lichen. Sedges. Birch ...
The animal life of the reserve is typical of the Mid-Urals taiga: moose, wolf, bear, rabbit, beaver, marten, ermine, weasel, shrews and other rodents. Scientists on the reserve have recorded 48 species of mammals. [1] 185 species of birds have been recorded, of which 125 are nesting. [8]
An Alpine chough in flight at 3,900 m (12,800 ft). Organisms can live at high altitude, either on land, in water, or while flying.Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes.
