It demonstrates both the diversity of responses that are shown and the underlying principles of gas exchange and transport for a wide range of organisms.This 1991 book reviews the various metabolic and functional mechanisms that animals possess in order to live successfully in their own particular, often unique, environments.

The book's purpose is to demonstrate both the diversity of responses that are shown (be they biochemical, physiological, or behavioral) and to demonstrate the underlying principles of gas exchange and transport for a wide range of diverse organisms. What results is a useful review and analysis of our modern understanding of the respiratory physiology of helminths (parasitic worms), crustacea, amphibians, reptiles, birds, and mammals. The approach taken by the editors is essentially comparative and the individual authors were chosen so as to provide a useful, complementary view of the subject.List of contributors; Preface; Does comparative respiratory physiology have a role in evolutionary biology (and vice versa)? W. W. Burggren; Energy metabolism in helminths P. Kohler; The role of carbonic anhydrase within the tissues, with special reference to striated muscle G. Gros; Multiple strategies in oxygen and carbon dioxide transport by haemoglobin F. B. Jensen; Respiratory gas exchange and the regulation of acid-base status in decapodan crulSv
