Amphibians are the extant descendants of the first vertebrate class to successfully colonize terrestrial environments; hence they occupy a unique position between fish and reptiles. Amphibian skin provides essentially no resistance to evaporative water loss, and consequently daily water turnover rates are an order of magnitude greater than in other terrestrial vertebrate groups. This has led to a suite of physiological, morphological and behavioural adaptations that have allowed a successful terrestrial existence in spite of this apparently spendthrift water retention strategy. Ecological and Environmental Physiology of Amphibians provides a synthesis of current research on the comparative physiology of amphibians with a particular emphasis on water balance. It adopts a strong environmental perspective and includes a wealth of information on ecology, phylogeny and development. As with other books in the Ecological and Environmental Physiology Series, the emphasis in this book is on the unique physiological characteristics of the amphibians, although the latest experimental techniques and future research directions are also considered. This accessible text is suitable for both graduate students and researchers in the fields of amphibian comparative physiology and physiological ecology, including specialist courses in amphibian ecology. It will also be of value and use to the many professional herpetologists requiring a concise overview of the topic.

Mammals are the so-called "pinnacle" group of vertebrates, successfully colonising virtually all terrestrial environments as well as the air (bats) and sea (especially pinnipeds and cetaceans). How mammals function and survive in these diverse environments has long fascinated mammologists, comparative physiologists and ecologists.Ecological and Environmental Physiology of Mammals explores the physiological mechanisms and evolutionary necessities that have made the spectacular adaptation of mammals possible. It summarises our current knowledge of the complex and sophisticated physiological approaches that mammals have for survival in a wide variety of ecological and environmental contexts: terrestrial, aerial, and aquatic. The authors have a strong comparative and quantitative focus in their broad approach to exploring mammal ecophysiology. As with other books in the Ecological and Environmental Physiology Series, the emphasis is on the unique physiological characteristics of mammals, their adaptations to extreme environments, and current experimental techniques and future research directions are also considered.This accessible text is suitable for graduate level students and researchers in the fields of mammalian comparative physiology and physiological ecology, including specialist courses in mammal ecology. It will also be of value and use to the many professional mammologists requiring a concise overview of the topic.
