Summary:

"Osmoregulation and Drinking in Vertebrates" presents some of the most exciting recent advancements in the area of osmoregulation, from the control of gene expression to whole animal response. The volume discusses the differences and similarities in the drinking response between a number of vertebrate groups including both aquatic and terrestrial organisms. As such, this volume will be of interest to all those working in the fields of marine and freshwater biology, comparative physiology and endocrinology and molecular biology of ion transporters and water channels.
