The fennec fox's large ears help keep it cool: when the blood vessels dilate, blood from the body cycles in and dissipates over the expanded surface area. [1]A xerocole (from Greek xēros / ˈ z ɪ r oʊ s / 'dry' and Latin col(ere) 'to inhabit'), [2] [3] [4] is a general term referring to any animal that is adapted to live in a desert.
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms , the climate in which they live, and any other non-living influences on the habitat .
Desert roaming elephants have developed certain adaptations for desert life and tend to have relatively broader feet, longer legs and smaller bodies than other African bush elephants. They are herbivorous, and their diet varies with the change of the seasons. They may walk up to 70 kilometers at night to find water points, which is the cause of ...
Annual growth rings indicate the animal's age. The rams may rub their own horns to improve their field of view. [7] Both rams and ewes use their horns as tools to break open cactus, which they consume, and for fighting. [8] Desert bighorn sheep typically live for 10–20 years. [9] The typical diet of a desert bighorn sheep is mainly grasses. [7]
Many desert animals (and plants) show especially clear evolutionary adaptations for water conservation or heat tolerance and so are often studied in comparative physiology, ecophysiology, and evolutionary physiology. One well-studied example is the specializations of mammalian kidneys shown by desert-inhabiting species. [81]
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?

The round-tailed ground squirrel (Xerospermophilus tereticaudus), known as "Ardillón cola redonda" in Spanish, live in the desert of the Southwestern United States and Northwestern Mexico. They are called "ground squirrels" because they burrow in loose soil, often under mesquite trees and creosote bushes.
