This leads to the lower evaporative loss from the body of the desert bird. Cacti have also developed succulent tissue, waxy skin, prickly spines, and a specialized root system to take every advantage in their harsh ecosystems. As a result, the diversity of plant life in deserts is likely to decline as climate change continues. Mesquite has long, deep roots that help it reach water sources far below the ground.
