This book is a basic account of the synecology of deserts. It covers a wide range of topics that have been studied extensively in other biomes, but not yet in arid lands. These include predation and anti-predatory strategies, parasitic and allied interactions, herbivory and plant defences. Finally, community processes such as communal and social behaviour among animals, aggression, population effects, pollination, seed dispersal, competition, and food webs, are discussed. By drawing attention to both what is and what is not known with regard to desert ecology, a basis for future research is provided.
