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. The main challenges xerocoles must overcome are lack of water and excessive heat. To conserve water they avoid evaporation and concentrate excretions (i.e. urine and ...
Xerophiles are "xerotolerant", meaning tolerant of dry conditions. They can often survive in environments with water activity below 0.8; above which is typical for most life on Earth. Typically xerotolerance is used with respect to matrix drying, where a substance has a low water concentration. These environments include arid desert soils.
Tardigrades live over the entire world, including the high Himalayas. [4] Tardigrades are also able to survive temperatures of close to absolute zero (−273 °C (−459 °F)), [5] temperatures as high as 151 °C (304 °F), radiation that would kill other animals, [6] and almost a decade without water. [7]
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 ...
It is the smallest gray wolf subspecies and a specialized xerocole (arid-adapted) animal that normally lives in smaller familial packs. Arabian wolves are omnivorous and opportunistic eaters; they consume small to medium-sized prey, from insects, reptiles and birds to rodents and small ungulates , such as young Nubian ibex and several species ...
Sleeping the season away. If an animal’s physiology, diet, or other characteristics don’t allow it to stay warm and/or find sufficient food during the winter, an additional set of survival ...
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. Deserts are arid regions that are generally associated with warm temperatures; however ...
The skies are teeming, too: a southern desert shrike, a bird that impales its prey upon spiky branches, oil-black desert ravens and even a critically endangered Egyptian vulture. But most common ...
