The Climate of Arid Environments,Deserts are not always characterized by great heat and extensive sand dunes. A variety of biotopes and temperature regimes are found in temperate and subtropical deserts and extremely low temperatures are typical for polar deserts. As pointed out by Logan (1968), an important common characteristic of all deserts is their aridity.

Quiescence can be induced by different kinds of environmental stress, including extreme temperatures, dehydration, high salt concentrations and anoxia. During increasing stress, some organisms are able to shut down metabolism to an undetectable level.

Phenological Adaptations,duced food availability. Breeding and the initial production of offspring are particularly vulnerable to the desert climate and in many invertebrates fecundity is reduced during drought years or the dry season (Riechert 1979).

Cold Hardiness in Terrestrial Arthropods,ds. The intriguing question as to how poikilotherm animals are able to survive temperatures far below the melting points of their haemolymph has puzzled many biologists. Although many problems remain unanswered, their work has revealed the general principles of physiological and biochemical adaptations to low temperatures.
