A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. [1] The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal ...
The Canadian boreal region contains the largest area of wetlands of any ecosystem of the world, serving as breeding ground for over 12 million waterbirds and millions of land birds, the latter including species as diverse as vultures, hawks, grouse, owls, hummingbirds, kingfishers, woodpeckers, and passerines (or perching birds, often referred ...
The boreal forest/taiga supports a relatively small variety of highly specialized and adapted animals, due to the harshness of the climate. Canada's boreal forest includes 85 species of mammals, 130 species of fish, and an estimated 32,000 species of insects. [37] Insects play a critical role as pollinators, decomposers, and as a part of the ...
The boreal woodland caribou (Rangifer tarandus caribou; but subject to a recent taxonomic revision.See Reindeer: Taxonomy), also known as Eastern woodland caribou, boreal forest caribou and forest-dwelling caribou, is a North American subspecies of reindeer (or caribou in North America) found primarily in Canada with small populations in the United States.
However, studies of tree rings from all parts of the boreal zone have indicated an inverse growth response to temperature, likely as a result of direct temperature and drought stress. As global warming increases, negative effects on growth are likely to become more widespread as ecosystems and species will be unable to adapt to increasingly ...
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]
White spruce is the predominant tree species in the Boreal White and Black Spruce (BWBS), except in the Fort Nelson area where the poorly drained lowlands are dominated by black spruce. Engelmann spruce is absent, though some white × Engelmann hybrids may occur at southern margins of the zone bordering the SBS zone.
It is also found on parts of the Fundy coast in Maine and the Maritimes, the northern parts of this ecoregion where the summers are cool. The coniferous forest goes by many names, including: Boreal forest, fir-spruce forest, the North Woods, and the taiga. It is noted in New England for its "harsh" conditions such as cold, subarctic ...
