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. Deserts are arid regions that are generally associated with warm temperatures; however ...
Most grasshoppers are polyphagous, eating vegetation from multiple plant sources, [22] but some are omnivorous and also eat animal tissue and animal faeces. [23] In general their preference is for grasses, including many cereals grown as crops. [24] The digestive system is typical of insects, with Malpighian tubules discharging into the midgut.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.

[1] Some species of Jerboa are known to have a diet that consists of insects, plants, and sometimes seeds. They use their two front legs to gather food. [5]
Increasingly frequent and severe heat waves in the Southwest are damaging some desert plants known for thriving in harsh conditions. Saguaro cacti and agave have both suffered in sweltering ...
Water activity, a thermodynamical value denoted a w, is defined as the partial water vapor pressure p in equilibrium with the substance relative to (divided by) the (partial) vapor pressure of pure water p* at the same temperature: The thermodynamical water activity is thus equal to the relative humidity (RH), and the chemical activity of pure ...
