Yukon Wolf
The Interior Alaskan wolf (''Canis lupus pambasileus''), also known as the Yukon wolf, is a subspecies of gray wolf native to parts of British Columbia, the Northwest Territories, Interior Alaska and Yukon. Taxonomy It is recognized as a subspecies of ''Canis lupus'' in the taxonomic authority ''Mammal Species of the World (2005)''. It was first described in 1905 by the American zoologist Daniel Elliot as ''Canis pambasileus'' and with the name "autocrat timber wolf", based on a specimen from the Susitna River, Mount McKinley region, Alaska. Elliot distinguishes this wolf by the teeth in both jaws being large and heavy, and along with the skull exceed those of ''C. l. occidentalis'' (the Northwestern wolf) of a comparable body size. This wolf's coat ranges from black to white or a mix of both. In 1944, the American zoologist Edward Goldman recognized this wolf as ''Canis lupus pambasileus'' Elliot, 1905 and with the name "Interior Alaskan wolf". Physiology Description The wol ...

Denali National Park
Denali National Park and Preserve, formerly known as Mount McKinley National Park, is an American national park and preserve located in Interior Alaska, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompass which is larger than the state of New Hampshire. On December 2, 1980, Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga, with tundra at middle elevations, and glaciers, snow, and bare rock at the highest elevations. The longest glacier is the Kahiltna Glacier. Wintertime activities include dog sledding, cross-country skiing, and snowmobiling. The park received 594,660 recreational visitors in 2018. History Prehistory and protohistory Human habitation in the Denali Region extends to more than 11,000 years before the present, with documented sites just outside park boundaries dated to more than 8,000 years before the present.

Canine Distemper
Canine distemper virus (CDV) (sometimes termed footpad disease) is a viral disease that affects a wide variety of mammal families, including domestic and wild species of dogs, coyotes, foxes, pandas, wolves, ferrets, skunks, raccoons, and felines, as well as pinnipeds, some primates, and a variety of other species. CDV does not affect humans. In canines CDV affects several body systems, including the gastrointestinal and respiratory tracts and the spinal cord and brain. Common symptoms include high fever, eye inflammation and eye/nose discharge, labored breathing and coughing, vomiting and diarrhea, loss of appetite and lethargy, and hardening of nose and footpads. The viral infection can be accompanied by secondary bacterial infections and can present eventual serious neurological symptoms. Canine distemper is caused by a single-stranded RNA virus of the family ''Paramyxoviridae'' (the same family of the viruses that causes measles, mumps, and bronchiolitis in humans). The d ...

Boreal Woodland Caribou
The boreal woodland caribou (''Rangifer tarandus caribou''; but subject to a recent taxonomic revision. See Reindeer: taxonomy), also known as woodland caribou, boreal forest caribou and forest-dwelling caribou, is a North American subspecies of reindeer (or caribou in North America) found only in Canada. Unlike the Porcupine caribou and barren-ground caribou, boreal woodland caribou are primarily (but not always) sedentary. In their 2012 report entitled "Recovery Strategy for the Woodland Caribou (Rangifer tarandus caribou), Boreal population, in Canada", Environment Canada and SARA refer to the woodland caribou as "boreal caribou". "Woodland Caribou (''Rangifer tarandus caribou''), Boreal population herein referred to as "boreal caribou", assessed in May 2002 as threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). The boreal woodland caribou is the third largest of the caribou ecotypes after Selkirk Mountain caribou and Osborn's caribou (see Re ...

Moose
The moose (in North America) or elk (in Eurasia) (''Alces alces'') is a member of the New World deer subfamily and is the only species in the genus ''Alces''. It is the largest and heaviest extant species in the deer family. Most adult male moose have distinctive broad, palmate ("open-hand shaped") antlers; most other members of the deer family have antlers with a dendritic ("twig-like") configuration. Moose typically inhabit boreal forests and temperate broadleaf and mixed forests of the Northern Hemisphere The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's Nort ... in temperate to subarctic climates. Hunting and other human activities have caused a reduction in the size of the moose's range over time. It has been reintroduced to some of its former habitats. Currently, most moose occ ...

Teslin, Yukon
The community of Teslin (Tlingit: ''Desleen'') includes the Village of Teslin in Yukon, Canada. Teslin is situated at historical Mile 804 on the Alaska Highway along Teslin Lake. The Hudson's Bay Company established a small trading post at Teslin in 1903 (i.e. Teslin Post). Teslin is home to the Teslin Inland Tlingit First Nations. The name Teslin came from a Tlingit word "Teslintoo." Teslin has one of the largest Native populations in Yukon. Much of the community's livelihood revolves around traditional hunting, trapping and fishing. Demographics ;Village of Teslin In the 2021 Census of Population conducted by Statistics Canada, Teslin had a population of living in of its total private dwellings, a change of from its 2016 population of .

Kluane National Park
Kluane National Park and Reserve (; french: Parc national et réserve de parc national de Kluane) are two protected areas in the southwest corner of the territory of Yukon. The National Park Reserve was set aside in 1972 to become a national park, pending settlement of First Nations land claims. It covered an area of . When agreement was reached with the Champagne and Aishihik First Nations over an eastern portion of the Reserve, that part—about —became a national park in 1993, and is a unit of the national park system administered co-operatively with Parks Canada. The larger western section remains a Reserve, awaiting a final land claim settlement with the Kluane First Nation. The park borders B.C. to the south, while the Reserve borders both B.C. to the south, and the United States (Alaska) to the south and west. The Reserve includes the highest mountain in Canada, Mount Logan () of the Saint Elias Mountains. Mountains and glaciers, including Donjek Glacier, dominate the ...

Arctic Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained gre ...

Subalpine
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in ...

Alpine Tundra
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated alpine climate, 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 tundra#Arctic tundra, polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra ecotone, transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation it ends at the snow line where snow and ice persist through summer. Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by adiabatic cooling of air, and is similar to polar climate. Geography Alpine tundra occurs at hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boreal Forest
Taiga (; rus, тайга́, p=tɐjˈɡa; relates to Mongolic and Turkic languages), generally referred to in North America as a boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest has been called the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaidō). The main tree species, depending on the length of the growing season and summer temperatures, vary across the world. The taiga of North America is mostly spruce, Scandinavian and Finnish taiga consists of a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
