Each volume provides a state-of-the-art review and synthesis of topics that are relevant to how that specifi c group of organisms have evolved and coped with the environmental characteristics of their habitats. T e series is intended for stu- dents, researchers, consultants, and other professionals in the fi elds of physiology, physiological ecology, ecology, and evolutionary biology. A Series Advisory Board assists in the commissioning of titles and authors, development of volumes, and promotion of the published works. T is Board comprises more than 50 internationally recognized experts in ecological and environmental physiology, providing a combination of both depth and breadth to proposal evaluation and series oversight. T e reader is encouraged to visit the EEPS website for additional information and the latest volumes (h ttp://www.eeps-oxford.com/) . If you have ideas for new titles in this series or just wish to comment on EEPS, please do not hesitate to contact the Series Editor, Warren Burggren (University of North Texas; burg- C ontents A cknowledgements xii F oreword xiii 1 .
