Thinhorn Sheep
''Ovis dalli'', also known as the Dall sheep or thinhorn sheep, is a species of wild sheep native to northwestern North America. ''Ovis dalli'' contains two subspecies: '' Ovis dalli dalli'' and '' Ovis dalli stonei''. ''O. dalli'' live in mountainous alpine habitats distributed across northwestern British Columbia, the Yukon, Northwest Territories and Alaska. They browse a variety of plants, such as grasses, sedges and even shrubs, such as willow, during different times of the year. They also acquire minerals to supplement their diet from mineral licks. Like other ''Ovis'' species, the rams engage in dominance contests with their horns. Taxonomy and genetics The specific name ''dalli,'' is derived from William Healey Dall (1845–1927), an American naturalist. The common name, Dall's sheep or Dall sheep is often used to refer to the nominate subspecies, ''O. d. dalli''. The other subspecies, ''O. d. stonei'', is called the Stone sheep. Originally, the subspecies ''O. d. dalli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sexual Dimorphism
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tatshenshini-Alsek Provincial Park
Tatshenshini-Alsek Park or Tatshenshini-Alsek Provincial Wilderness Park is a provincial park in British Columbia, Canada. The park is in size. It was established in 1993 after an intensive campaign by Canadian and American conservation organizations to halt mining exploration and development in the area, and protect the area for its strong natural heritage and biodiversity values. The park is located in the very northwestern corner of British Columbia, bordering the American state of Alaska and the Canadian Yukon Territory. Nestled between the Yukon's Kluane National Park and Reserve and Alaska's Glacier Bay and Wrangell–St. Elias National Parks and Preserves, the park includes all land in British Columbia west of the Haines Highway. It is part of the Kluane-Wrangell-St. Elias-Glacier Bay-Tatshenshini-Alsek park system, and in 1994 was designated as a UNESCO World Heritage Site.

Kluane National Park And Reserve
Kluane National Park and Reserve (; ) are two protected areas in the southwest corner of the Provinces and territories of Canada, territory of Yukon. The National Park Reserve was set aside in 1972 to become a national park, pending settlement of First Nations in Canada, 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 British Columbia to the south, while the Reserve borders both British Columbia 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 Donj ...

Meadow
A meadow ( ) is an open habitat or field, vegetated by grasses, herbs, and other non- woody plants. Trees or shrubs may sparsely populate meadows, as long as they maintain an open character. Meadows can occur naturally under favourable conditions but are often artificially created from cleared shrub or woodland for the production of hay, fodder or livestock. Meadow habitats as a group are characterized as semi-natural grasslands, meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife and support flora and fauna that could not thrive in other habitats. They are ecologically important since they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering if the vegetation is high enough. Intensified agricultural practices (too frequent mowing, use of mineral fertilizers, manure and insecticides) may lead to declin ...

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 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 merges with polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra 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 high enough altitude at any latitude. Portions of montane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
