Dolphin-Union Caribou
Dolphin and Union Caribou, Dolphin and Union caribou herd, Dolphin-Union, locally known as Island Caribou, are a migratory population of barren-ground caribou, ''Rangifer tarandus groenlandicus,'' that occupy Victoria Island in the Canadian Arctic Archipelago and the nearby mainland. They are endemic to Canada. They migrate across the Dolphin and Union Strait from their summer grazing on Victoria Island to their winter grazing area on the Nunavut-Northwest Territories mainland in Canada. It is unusual for North American caribou to seasonally cross sea ice and the only other caribou to do so are the Peary caribou who are smaller in size and population. They were listed as Endangered by Committee on the Status of Endangered Wildlife in Canada (COSEWIC) since November 2017. Morphology Pelage The pelage of the Dolphin and Union Caribou is white in winter and slate-grey with white legs and under-parts in summer like the Peary caribou. The Dolphin and Union Caribou are slightly darke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mammals Of Canada
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Caribou Herds And Populations In Canada
Caribou herds in Canada are discrete populations of seven subspecies that are represented in Canada. Caribou can be found from the High Arctic region south to the boreal forest and Rocky Mountains and from the east to the west coasts. Arctic peoples, including the Caribou Inuit, the inland-dwelling Inuit of the Kivalliq Region in northern Canada, the Caribou Clan in Yukon, the Iñupiat, the Inuvialuit, the Hän, the Northern Tutchone, and the Gwich'in, who followed the Porcupine caribou (also known as Grant's caribou) for millennia, have depended on caribou for food, clothing, and shelter.(Banfield 1961:170; Kurtén 1968:170) COSEWIC COSEWIC (2011) Designatable units for caribou (Rangifer tarandus) in Canada. Committee on the Status of Endangered Wildlife in Canada (COSEWIC), Ottawa, Ontario, 88 pp. divided caribou ecotypes in Canada into 12 "designatable units" (DU), an adaptation of "evolutionarily significant units" for purposes of conservation and monitoring that, for the mo ...

Arctic Institute Of North America
The Arctic Institute of North America is a multi-disciplinary research institute and educational organization located in the University of Calgary. It is mandated to study the North American and circumpolar Arctic in the areas of natural science, social science, arts and the humanities. In addition, it acquires, preserves and disseminates information on environmental, physical, and social conditions in the north. The institute was created in 1945 by a Canadian act of Parliament as a non-profit membership organization, and also incorporated in the state of New York. History The idea of the institute began in the early 1940s when a group of Canadians discussed ways that Canada could increase administrative, scientific and technical expertise in the Arctic. By 1944, a binational organization that included Canada and the United States, with room for Greenland, Newfoundland, and Labrador was established. Offices were opened at McGill University in Montreal, Quebec, Canada. Geophysicis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kugluktuk
Kugluktuk (, ; Inuktitut syllabics: ; ), formerly known as Coppermine until 1 January 1996, is a hamlet located at the mouth of the Coppermine River in the Kitikmeot Region of Nunavut, Canada, on Coronation Gulf, southwest of Victoria Island. It is the westernmost community in Nunavut, near the border with the Northwest Territories. The traditional language of the area is Inuinnaqtun and is written using the Latin alphabet, rather than the syllabics of the Inuktitut writing system.

Yellowknife
Yellowknife (; Dogrib: ) is the capital, largest community, and only city in the Northwest Territories, Canada. It is on the northern shore of Great Slave Lake, about south of the Arctic Circle, on the west side of Yellowknife Bay near the outlet of the Yellowknife River. Yellowknife and its surrounding water bodies were named after a local Dene tribe, who were known as the "Copper Indians" or "Yellowknife Indians", today incorporated as the Yellowknives Dene First Nation. They traded tools made from copper deposits near the Arctic Coast. Its population, which is ethnically mixed, was 19,569 per the 2016 Canadian Census.

Sea Ice
Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. General features and dynamics Sea ice does not simply grow and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
