Melville Island (Northwest Territories And Nunavut)
Melville IslandCoordinates are located on the NWT side. (french: Île Melville; Inuktitut: ''ᐃᓗᓪᓕᖅ, Ilulliq'') is an uninhabited island of the Arctic Archipelago with an area of . It is the 33rd largest island in the world and Canada's eighth largest island. Mountains on Melville Island, some of the largest in the western Canadian Arctic, reach heights of . There are two subnational pene-exclaves that lie west of the 110th meridian and form part of the Northwest Territories. These can only be reached by land from Nunavut or boat from the Northwest Territories. Melville Island is shared by the Northwest Territories, which is responsible for the western half of the island, and Nunavut, which is responsible for the eastern half. The border runs along the 110th meridian west. Geography The island has little or no vegetation. Where continuous vegetation occurs, it usually consists of hummocks of mosses, lichens, grasses, and sedges. The only woody specie ...

Enclave And Exclave
An enclave is a territory (or a small territory apart of a larger one) that is entirely surrounded by the territory of one other state or entity. Enclaves may also exist within territorial waters. ''Enclave'' is sometimes used improperly to denote a territory that is only partly surrounded by another state. The Vatican City and San Marino, both enclaved by Italy, and Lesotho, enclaved by South Africa, are completely enclaved sovereign states. An exclave is a portion of a state or district geographically separated from the main part by surrounding alien territory (of one or more states or districts etc). Many exclaves are also enclaves, but not all: an exclave can be surrounded by the territory of more than one state. The Azerbaijani exclave of Nakhchivan is an example of an exclave that is not an enclave, as it borders Armenia, Turkey and Iran. Semi-enclaves and semi-exclaves are areas that, except for possessing an unsurrounded sea border (a coastline contiguous with interna ...

Arctic Wolf
The Arctic wolf (''Canis lupus arctos''), also known as the white wolf or polar wolf, is a subspecies of grey wolf native to the High Arctic tundra of Canada's Queen Elizabeth Islands, from Melville Island to Ellesmere Island.https://ecoregions.appspot.com/ Unlike some populations that move between tundra and forest regions, Arctic wolves spend their entire lives north of the northern treeline. Their distribution to south is limited to the northern fringes of the Middle Arctic tundra on the southern half of Prince of Wales and Somerset Islands. It is a medium-sized subspecies, distinguished from the northwestern wolf by its smaller size, its whiter colouration, its narrower braincase,Goldman, E. A. (1964). Classification of wolves. In ''The Wolves of North America'' Part 2. Young, S. P. & Goldman, E. A. (Eds.) New York: Dover Publs. p. 430. and larger carnassials. Since 1930, there has been a progressive reduction in size in Arctic wolf skulls, which is likely the result o ...

Northern Collared Lemming
The northern collared lemming or Nearctic collared lemming (''Dicrostonyx groenlandicus''), sometimes called the Peary Land collared lemming in Canada, is a small lemming found in Arctic North America and Wrangel Island. At one time, it was considered to be a subspecies of the Arctic lemming (''Dicrostonyx torquatus''). Some sources believe several other species of collared lemmings found in North America are actually subspecies of ''D. groenlandicus''. Description It has a short chunky body covered with thick grey fur with a thin black stripe along its back and light grey underparts. It has small ears, short legs and a very short tail. It has a pale brown collar across its chest. In winter, its fur turns white, and it has large digging claws on its front feet. It is 14 cm long with a 1.5 cm tail and weighs about 40 g. Distribution and habitat It is found in the tundra of northern Canada, Alaska and Greenland. A disjunct population is also present on Wrangel Island in ...

Muskox
The muskox (''Ovibos moschatus'', in Latin "musky sheep-ox"), also spelled musk ox and musk-ox, plural muskoxen or musk oxen (in iu, ᐅᒥᖕᒪᒃ, umingmak; in Woods Cree: ), is a hoofed mammal of the family Bovidae. Native to the Arctic, it is noted for its thick coat and for the strong odor emitted by males during the seasonal rut, from which its name derives. This musky odor has the effect of attracting females during mating season. Its Inuktitut name "umingmak" translates to "the bearded one". Its Woods Cree names "mâthi-môs" and "mâthi-mostos" translate to "ugly moose" and "ugly bison", respectively. Muskoxen primarily live in Greenland and the Canadian Arctic of the Northwest Territories and Nunavut, with reintroduced populations in the American state of Alaska, the Canadian territory of Yukon, and Siberia, and an introduced population in Norway, part of which emigrated to Sweden, where a small population now lives. Evolution Extant relatives The musko ...

Peary Caribou
The Peary caribou (''Rangifer arcticus pearyi'') is a subspecies of caribou found in the High Arctic islands of Nunavut and the Northwest Territories in Canada. They are the smallest of the North American caribou, with the females weighing an average of and the males . In length the females average and the males . Like other caribou, both the males and females have antlers. The males grow their antlers from March to August and the females from June to September, and in both cases the velvet is gone by October. The coat of the caribou is white and thick in the winter. In the summer it becomes short and darker, almost slate-grey in color. The coat is made up of hollow hair which helps to trap warmer air and insulate the caribou. The males become sexually mature after two years and the females after three years. Breeding is in the fall and depends on the female having built up sufficient fat reserves. The gestation period last for seven to eight months and one calf is produced. ...

Polar Bear
The polar bear (''Ursus maritimus'') is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore. A boar (adult male) weighs around , while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, pola ...

Fjord
In physical geography, a fjord or fiord () is a long, narrow inlet with steep sides or cliffs, created by a glacier. Fjords exist on the coasts of Alaska, Antarctica, British Columbia, Chile, Denmark, Germany, Greenland, the Faroe Islands, Iceland, Ireland, Kamchatka, the Kerguelen Islands, Labrador, Newfoundland, New Zealand, Norway, Novaya Zemlya, Nunavut, Quebec, the Patagonia region of Argentina and Chile, Russia, South Georgia Island, Tasmania, United Kingdom, and Washington state. Norway's coastline is estimated to be long with its nearly 1,200 fjords, but only long excluding the fjords. Formation A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock. According to the standard model, glaciers formed in pre-glacial valleys with a gently sloping valley floor. The work of the glacier then left an overdeepened U-shaped valley that ends abruptly at a valley or trough end. Such valleys are fjo ...

Salix Herbacea
''Salix herbacea'', the dwarf willow, least willow or snowbed willow, is a species of tiny creeping willow (family Salicaceae) adapted to survive in harsh arctic and subarctic environments. Distributed widely in alpine and arctic environments around the North Atlantic Ocean, it is one of the smallest of woody plants. Distribution ''Salix herbacea'' is adapted to survive in harsh environments, and has a wide distribution on both sides of the North Atlantic, in arctic northwest Asia, northern Europe, Greenland, and eastern Canada, and further south on high mountains, south to the Pyrenees, the Alps and the Rila in Europe, and the northern Appalachian Mountains in the eastern United States. It grows in tundra and rocky moorland, usually at over elevation in the south of its range but down to sea level in the Arctic.Meikle, R. D. (1984).

Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus '' Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ...

Grass
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of bio ...
