The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...
Mount Elbert rises through multiple biotic zones, with alpine tundra at its peak.. The Rocky Mountains range in latitude between the Liard River in British Columbia (at 59° N) and the Rio Grande in New Mexico (at 35° N), and in height up to the highest peak, Mount Elbert at 14,440 feet (4,400 m), taking in great valleys such as the Rocky Mountain Trench and San Luis Valley.
Wildlife includes large colonies of seabirds on the islands and waterbirds and shorebirds in the many wetlands such as the Kuskokwim River delta, one of the largest waterbird nesting areas in the world and home to the world's largest communities of tundra swan, most of the world's emperor goose, and half of the world's black brant (Branta ...
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...
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 alpine tundra merges with polar tundra.
A list of tundra ecoregions from the World Wide Fund for Nature (WWF) includes: Antarctic realm [1] Adelie Land tundra: Adélie Land: Central South Antarctic ...
Because the Gulf Stream has a moderating effect, portions of Iceland have an Oceanic climate (subpolar variety) (Köppen climate classification: Cfc).But most of the ecoregion is Tundra climate (Köppen climate classification: ET), a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess ...
The Interior Yukon–Alaska alpine tundra ecoregion (WWF ID: NA1111) covers alpine, sub-alpine, and boreal forest areas along the cordillera (chain of mountain ranges) of Interior Alaska and south-central Yukon Territory. Geologically, they are the disjunct uplands of the Yukon–Tanana terrane plus a southern extension of the Brooks Range. The ...
