Other significant factors that have hampered terrestrial biotic evolution are the harsh climate, the ice cover that completely engulfed the continent during the Pleistocene glaciations, and the present limited number of ice-free land areas, which are restricted primarily to the coastal fringes and nunataks (mountain peaks surrounded by the ice cap). Additionally, the slow-growing shrub has an upright habit of arching branches growing 1 to 3 ft. (0.3 1 m) tall and wide. The temperatures are extremely low (less than 50oF/10oC in summer, and around -22oF/-30oC in winter) and rainfall is scarce (less than 1.5 in/40 mm per year). Examples of biomes: Desert: succulents that store water, spiny leaves, low precipitation, high evaporation, extreme temperatures Tundra: low trees and shrubs, small woody plants, cold, dry, windy conditions most of the year Rainforest: dense jungle, lush vegetation, heavy rain, high humidity, tropical, nutrient deficient soil The dry, barren stems become plump with moisture, lush leaves appear, and bright crimson flowers bloom. It is the interplay of these factors during summer that determines whether temperatures are warm enough and moisture is sufficient to allow plants to grow. Desert plants and animals must be able to tolerate extremes of both heat and cold. Corrections? In addition, the polar regions spend a large part of the year in darkness. The bushes may be used in the western Canadian Arctic by the Inuit for fuel or for mats, and in former times the wood was made into arrow shafts.
