Desert Biome By: Holli Wright & Jordan Durst
Location • Southern states: Arizona, Texas, New Mexico • Australia • South West Africa • South America
Temperature/Rainfall Average Temperature (Australia): 35.61 degrees C = 96.10 degrees F Average Rainfall in a year (Australia): 6.62 mm = 0.26 in
Types • Arid Desert – plant and animal life • Hyper arid Desert – little to no vegetation and animal life • Hot/Dry Desert • Winter Temperatures: 20-25 degrees Celsius • Summer Temperatures: 43.5-49 degrees Celsius • Cold Desert • Winter Temperatures: -2-4 degrees Celsius • Summer Temperatures: 21-26 degrees Celsius
Vertical Stratification • Soil – Saline or alkaline (sand) • Plants: • Shrubs • Cactus • Plants are called Xerophytes = plants that are able to survive in an environment with little water or moisture • Vegetation: • Sparse grasslands • Shrub lands • Woodlands
Animal Adaptations • Large extremities to dissipate heat • Small body size to dissipate heat • Reduce heat input by staying out of the sun and staying in the shade • Example: • Kangaroo Rat -> can survive with little water by converting the dry seeds that they eat into water. These animals don’t sweat or pant to keep their bodies cool in the hot sun. Kangaroo rats spend most of their day in burrows where the air is moist and cool.
