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 ...
Reindeer also travel, feed, and rest together in the wild, sometimes forming super-herds of up to 500,000 animals. Tundra reindeer migrate between forest and tundra in these massive groups in an ...
The swans were a mix of trumpeters and tundras, both of which are protected by state and federal laws. Minnesota has the highest population of trumpeter swans in the lower 48 states. A survey in ...
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
The ecoregion to the south along the length is the High Arctic tundra, which is much drier (averaging only 100 mm/year of precipitation compared to the 400–600 mm/year in the Davis Highlands). [ 4 ]
Scientists have discovered a pristine fossil of a mummified saber-toothed kitten that had been frozen in the Russian tundra for about 37,000 years.
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 ...
