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 ...
The flora of the alpine tundra is characterized by plants that grow close to the ground, including perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [28] The flora is adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season.
This is a largely unspoilt environment home to large predators, although there is some development associated with tourism, especially at Kantishna near Denali Park, and some mining activity including the abandoned copper mining camp of Kennecott, Alaska in the Wrangell Mountains and coal mining at Nabesna and Healy, Alaska.
The Alaskan hare (Lepus othus), also known as the tundra hare, is a species of mammal in the family Leporidae. [2] They do not dig burrows and are found in the open tundra of western Alaska and the Alaska Peninsula in the United States. They are solitary for most of the year except during mating season, when they produce a single litter of up ...
An old castaway hut on the Antipodes Islands.. The islands constituting this ecoregion share a long history of isolation, both from other landmasses and each other. The isolation, combined with harsh climates characterised by low temperatures, strong westerly winds and few hours of sunlight in winter, have resulted in the evolution of many endemic plants and animals, though species richness is ...
This coast has an arctic climate warm enough to allow plant growth in late-June, July and August only, and even then frosts may occur. On the whole this is a damper, wetter area than the Low Arctic tundra ecoregion that continues along the coast west of here to Quebec. [2]
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 ...
These rocky islands support a variety of plant life, such as tussock grasses, that has adapted to the snowy and icy conditions.There are a number of endemic plant species including Poa cookii grass and the Kerguelen cabbage (Pringlea antiscorbutica), historically a source of vitamin C for sailors, is found on all the islands, not only the Kerguelens.
