In addition, the polar regions spend a large part of the year in darkness. Tundras are most common in the Low Arctic, and polar barrens are dominant in the High Arctic. They often have spines that protect their leaves and stems from being eaten by herbivores looking for food and moisture. Identifying features of the small desert tree are its tall branches, fleshy stems, and yellow flowers. and thermokarst lakes (formed from melting permafrost). Ultraviolet radiation, previously intercepted by the ozone layer, is detrimental to most life because it inhibits photosynthesis and increases mutation rates in DNA and damages epidermal tissues in plants and animals. 714 Wall St., downtown Los Angeles.

Circulation of air masses around the Earth transports industrial pollutants from temperate regions into the Arctic and Antarctic. Desert marigolds are flowering perennial plants found in the deserts of Mexico, Utah, California, and Arizona. However, there are also extremely cold deserts can also be found away from the poles at elevation, such as high up in the Andes Mountains in South America. Even though most algae and fungi are no longer classified within the plant kingdom, they are often still included in discussions of plant life. The flora and fauna of these islands are poorly developed, largely because of their isolation from potential sources of terrestrial biota. In some areas, notably west of Hudson Bay, a similar environment results in tundra grassland. The showy flowers measure 3 to 4 (7.5 10 cm) long. Photo courtesy of DonGato, Flickr.
