"Ecophysiology of Desert Arthropods and Reptiles" starts with a new classification of the world's deserts, based upon the type of precipitation to which they are subject and the effect of this on their faunas of arthropods and reptiles. This is followed by an account of microclimates and the avoidance of environmental extremes. Where thermoregulation is primarily behavioural, responses to water shortage are largely physiological. Seasonal activity and phenology are described, as well as adaptations for burrowing, the avoidance of enemies and defence. A comparative account of interspecific relationships, feeding specializations, and species diversity in the two taxa is described. The purpose of the book is to provide an up-to-date analysis that will stimulate further research.
