Campana said there was even a myth that the sharks could leap out of the water and seize caribou standing on ice. The United States this year listed polar bears as threatened under the U. Endangered Species Act because their sea ice habitat is shrinking, apparently due to global warming.

A thaw may mean that bears spend more time in the water. But less chill waters are unlikely to lure other big sharks, except perhaps the porbeagle, to polar regions, Campana said. Is it possible to live in the arctic sharks favor much warmer conditions. Killer whales, however, have been spotted further north in recent years.

Imagine for a moment that you are on an arctic expedition and spot a woolly arcric on land. Trees and other vegetation over large areas have been killed by heavy metals, sulphur dioxide and other contaminants released from smelters, with consequent problems of erosion and further environmental damage. The continuing cycles of freezing and thawing contribute to intense erosion and an ever-changing topography with wide local variability in soil and surface patterns, including polygons, circles, sorted and non-sorted stripes and mounds of soil with ice cores such as pingos. The relevance of temperature and light in the regulation of seasonal growth patterns and phenology suggests that warming may cause a disruption of both growth possiblle and survival, predictably affecting the large-scale ecosystem structure. When the contents of C and N were considered together C:N molar ratio: Figure 9the behavior differed from one species to another. The plant species composition is relatively uniform throughout most of the arctic forest which basically consists of one canopy layer with an under-vegetation of dwarf shrubs, mosses and lichens.

The annual growth or biomass increment of tundra plants is very low, and they are thus capable of supporting only a limited number is it possible to live in the arctic herbivorous animals. However, arctic forests are generally less exploited than the boreal forest to the south, largely because tree growth is slow and the trees are smaller and thus less adapted for wood products, regeneration is very slow and access is often difficult. They enjoy higher temperatures than their surroundings since the warmth of sunlight is retained in the plants and soil. The region contains a wide range of landscapes, from bare rock to swamp, glacier to meadow, mountain to lowland plain. Davis, A.
