A biome is a significant community of animals and plants which can be adapted to specific states. A desert biome is a region that receives less than 50 centimeters of rain annually, sometimes much less. Burrowing animals are usually more successful than surface dwellers.

Each desert biome is generally characterized by a dominant plant form. All are arid, but each is very distinct, with its climate and species of animals and plants.

Hot and dry desert

The Sahara is the biggest hit as well as dry biome. Its regions where rain is less than a centimeter and a half annually. The American Southwest is a leading dry as well as hot desert biome also. Another hot, dry deserts range from the Ethiopian and Australian deserts, and the Tour of India.

Rain shadows were formed in by some hot, dry bones. High mountains block wetness from these regions. The utter absence of moisture in the atmosphere leads to almost twice the heat gain in the day as in other temperate regions and more than twice the heat loss at night. Most hot, dry bones can also be situated at or close to the Tropic of Capricorn or the Tropic of Cancer, where the heated atmosphere which has lost its moisture high in equatorial regions comes to earth.

The mean temperature in this biome may be 68-77 degrees F., but extremes can be considerably higher, to 120 degrees or more. The temperature falls dramatically during the night. Rainfall is low, but focused in cloudbursts. Because fine material, with little to anchor it, has blown away, the soil is often coarse and gravelly.

Plants are small, thick leafed, and low. Cactus like yucca, and prickly pear, Ocotillo, agave and jujube are some plants of the biome.

Where there is water in the desert, big mammals like the chinkara, the Addax and the Oryx are uncovered, but burrowing mammals like the kangaroo mouse tend to be common, and reptiles are most common. Scorpions live in the hot, dry desert, in addition to ants along with other insects. Fowl range from the bustard. The Black Witch Moth is included by insects.

Semiarid Steppes

The sagebrush deserts of America’s Great Basin are semi arid. So are some areas of Northern Asia, Europe, and Northern Canada. These regions have quite cool nights. Precipitation is often concentrated, and low. Dew may provide more moisture than rainfall does. Rainfall may average 2-4 centimeters annually in some regions.

Cool nights allow plants as well as creatures to recuperate from warm dry days. Soils vary, from sandy and fine to loose rock. At the bottom of slopes is essentially loose heaps of stone, the upper bajada. Below that is the lower bajada, sandy plains, often underlain by cliche, tough layers of calcium carbonate. There's almost no water near the surface.

Plants of the semi-arid biome protect themselves with spines or hairs. Silvery reflective surface or white additionally keep plants cool. Many tough plants of the semi arid biome have a negative taste or smell, or are toxic. Species include sagebrush, creosote bush, cat's claw, and brittle bush.

Kangaroo rats jackrabbits, and skunks are a few mammals of the semi-arid biome. Lizards and snakes are common. Also found here are burrowing owls, and many migratory birds.

Coastal Desert

The coastal desert of South America, the Atacama, is the driest desert on earth. Its terrain has places of lava flows and sand, salt basins. Soils could possibly be salty too. Another coastal desert is the Namib, in southwest Africa. Coastal deserts have cool winters and long warm summers. Precipitation is low, but enough moisture to nurture lichen and cacti is sometimes provided by the fog.

Plants have wide, shallow roots, to catch fast any rain that falls. They swell to put away moisture, and thick stalks that pleat in dry circumstances, and may have tiny leaves. Plant species may contain saltbush, buckwheat bush, and rice grass. Critters of coastal deserts include coyotes, bald eagles, great horned owls, golden eagles, and badgers.

Cold Desert

Though it really is cold, it is a desert, mainly because of the lack of precipitation there. Antarctica is capped with ice, but has areas of bare rock too. Areas of northern Europe, North America and Greenland are also cold desert.

Summer chilly deserts normally have a brief moist. The winter is arid, perhaps with small quantities of moisture from snow. Winter temperatures are famously low, and summers are warm but not hot.

Plant life is widely scattered in Antarctica. There are lichens, mosses, a couple of fungi (which aren't plants, obviously), and a liverwort. The Antarctic hair grass and a pearlwort are the only two higher plants native there. Both can function with lower efficacy than at higher temperatures at the freezing point, though.

Lichens are a symbiotic organism consisting of an alga and also a fungus, which can function in extreme circumstances, and profit from the dearth of competition from more soft organisms. It puts in the cracks, and nourishes the lichen when snow falls.

Lighter cold deserts of the Northern hemisphere have more types of plants, but life there has to be hardy as well. The dry, cold challenges life.


Our preconceptions are challenged by learning about desert biomes. The desert just isn't void of life. Instead, it conceals an assortment of hardy plants and animals that utilize unique strategies to survive and use niches. Those who come to know the desert cannot help but respect its tough beauty.

That's information about Desert Biome Characteristics, may be useful and could increase our knowledge.
