Desert ecology is characterized by dry, alkaline soils, low net production and opportunistic feeding patterns by herbivores and carnivores. Other organisms' survival tactics are physiologically based. Such tactics include the completion of life cycles ahead of anticipated drought seasons, and storing water with the help of specialized organs. [12]
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. The cause of migration may be local climate, local availability ...

Representative fauna in tropical deserts include the armadillo lizard, banded Gila monster, bobcat, cactus wren and cactus ferruginous pygmy owl. Moreover, some other animals in deserts including coyote, desert bighorn sheep, desert kangaroo rat, desert tortoise, javelina and Mojave rattlesnake, cougar. Overall, different tropical deserts have ...
On Earth, seasons are the result of the axial parallelism of Earth's tilted orbit around the Sun. [2] [3] [4] In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant ...
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]
Non-mammalian animals that aestivate include North American desert tortoises, crocodiles, and salamanders. Some amphibians (e.g. the cane toad and greater siren) aestivate during the hot dry season by moving underground where it is cooler and more humid.
Similarly, the wet season in the Negev Desert of Israel extends from October through May. [30] At the boundary between the Mediterranean and monsoon climates lies the Sonoran Desert, which receives the two rainy seasons associated with each climate regime. [31] The wet season is known by many different local names throughout the world.
