Physiology of Elasmobranch Fishes: Structure and Interaction with Environment, Volume 34A of the Fish Physiology series, together with Physiology of Elasmobranch Fishes: Internal Processes, Volume 34B presents a broad exploration of our current knowledge of elasmobranch physiology. New scientific investigations on elasmobranchs have shed light on their evolutionary history and importance as representatives of ancestral vertebrates, and sophisticated laboratory and field studies have generated a large pool of previously unassembled date. Both of the volumes provide a comparative presentation of elasmobranch physiology, featuring authors with appropriate expertise and active research programs in the field. Each synthesizes the available date into a comprehensive review of the topic, while also comparing elasmobranchs to other groups of fishes and providing a perspective on future research problems and directions. The current state of knowledge of the elasmobranchs is surprisingly extensive, and these volumes bring to the reader an exhaustively referenced and up-to-date synthesis of the physiology of these fascinating animals. Key Features Coverage extends from molecular and cellular processes to field measurements of whole organismal responses to environmental factors Chapters include suggestions for future research and many draw attention to the potential physiological challenges faced with future climate change All chapters are written by researchers who are internationally recognized experts in their fields.
