G.P. Stamou describes the adaptive strategies that allow arthropods to cope with the severity of Mediterranean environments. After an introduction to the structure and function of Mediterranean-type ecosystems, ecophysiological adaptations to water stress and varying temperature are considered. Further, activity patterns and life cycle tactics are discussed in relation to the peculiarity of Mediterranean environments. Phenological patterns and population dynamics as well as community structures are also presented. The volume ends with a synthesis of life history tactics.G.P.
