Transcript of Desert Biome
The latitude range is 15-28° north and south of the equator. Their global range covers about 1/5 of the earth, including the world's great deserts: Sahara, Sonora, Thar, Kalahari and the Great Australian.
Approx. 1 in. of rain falls in dry deserts per year. http://theblondecoyote.files.wordpress.com/2012/08/p4161760.jpg
http://www.ucmp.berkeley.edu/glossary/gloss5/biome/deserts.html Plants Animals in the desert are highly specialized and have found unique ways of accessing and storing water. Large mammals are not prevalent in the desert because they can’t store sufficient amounts of water to thrive. Reptiles dominant the desert landscape. Often one can find burrowers and nocturnal animals that become avid hunters at night. Also Insects stick to the shade. Here are a few examples.
Plants are often short and shrub like. Plants keep their stomata closed during the day to reduce evaporation, opening them at night when less evaporation occurs. Spines often shade the surface of plants protecting them from predation as well as reducing the rate of transpiration ( leading to the prominence of cacti).Follicles also shade plants leading some shrubs to be shaggy in appearance. Some plants have adapted glossy leaves with reflective properties decreasing the amount of sun directly hitting the plants thus reducing the amount of transpiration that occurs. The desert adaptation of plants in this biome reflects the value of the resource of water.

Top Ten Deserts by Size Geography Facts Deserts cover about one fifth (20 percent) of the earth's land area.
The desert is a harsh environment with very little rainfall and extreme temperatures; a desert is defined as a region that gets less than ten inches of precipitation per year.
Occur where rainfall is less than 50 cm/year
