How do vertebrates get the oxygen they need, or even manage without it for shorter or longer periods of time? How do they sense oxygen, how do they take it up from water or air, and how do they transport it to their tissues? Respiratory system adaptations allow numerous vertebrates to thrive in extreme environments where oxygen availability is limited or where there is no oxygen at all. Written for students and researchers in comparative physiology, this authoritative summary of vertebrate respiratory physiology begins by exploring the fundamentals of oxygen sensing, uptake and transport in a textbook style. Subsequently, the reader is shown important examples of extreme respiratory performance, like diving and high altitude survival in mammals and birds, air breathing in fish, and those few vertebrates that can survive without any oxygen at all for several months, showing how evolution has solved the problem of life without oxygen.

Hopefully, this book will be taken off of the shelf frequently to be studied carefully over many years. More than 40 researchers were involved in this project, which examines respiration, circulation, and metabolism from ?sh to the land vertebrates, including human beings. A breathable and stable atmosphere ?rst appeared about 500 million years ago. Oxygen levels are not stable in aquatic environments and exclusively water-breathing ?sh must still cope with the ever-changing levels of O 2 and with large temperature changes. This is re?ected in their sophisticated count- current systems, with high O extraction and internal and external O receptors. 2 2 The conquest for the terrestrial environment took place in the late Devonian period (355–359 million years ago), and recent discoveries portray the gradual transitional evolution of land vertebrates.

Recently, physiology has expanded into related ?elds such as biochemistry, molecular biology, morphology and anatomy. In the light of the work in these ?elds, the introduction of DNA-based cladograms, which can be used to evaluate the likelihood of land vertebrates and lung?sh as a sister group, could explain why their cardio-respiratory control systems are similar. The diffusing capacity of a duck lung is 40 times higher than that of a toad or lung?sh. Certainly, some animals have evolved to rich high-performance levels.

Primitive fishes are a relatively untapped resource in the scientific search for insights into the evolution of physiological systems in fishes and higher vertebrates. Volume 26 in the Fish Physiology series presents what is known about the physiology of these fish in comparison with the two fish groups that dominate today, the modern elasmobranchs and the teleosts. Chapters include reviews on what is known about cardiovascular, nervous and ventilatory systems, gas exchange, ion and nitrogenous waste regulation, muscles and locomotion, endocrine systems, and reproduction. Editors provide a thorough understanding of how these systems have evolved through piscine and vertebrate evolutionary history. Primitive Fishes includes ground-breaking information in the field, including highlighs of the most unusual characteristics amongst the various species, which might have allowed these fishes to persist virtually unchanged through evolutionary time. This volume is essential for all comparative physiologists, fish biologists, and paleontologists. Provides an analysis of the evolutionary significance of physiological adaptations in "ancient fishes" Offers insights on the evolution of higher vertebrates The only single source that presents an in-depth discussion of topics related to the physiology of ancient fishes

Mit diesem Buch liegt nunmehr die deutsche Fassung des weltweit geschAtzten Lehrbuches zur Physiologie der Tiere von Knut Schmidt-Nielsen vor. Die prAgnante Darstellung von Fakten und der klare Stil sind sein Markenzeichen. Was zeichnet ein gut lesbares Lehrbuch aus, mit dem man sich exzellent auf PrA1/4fungen vorbereiten kann? Nicht die FA1/4lle an Fakten, sondern eine klare und gut verstAndliche Darstellung sowie die MAglichkeit, sich ZusammenhAnge selbst zu erschlieAen und so in dieses Wissensnetz Fakten einzubauen. Diesen Anspruch vermag Schmidt-Nielsen in seinem bereits in der 5. englischen Auflage vorliegenden Lehrbuch auf exzellente Weise zu erfA1/4llen. Der Schwerpunkt des Buches liegt auf den Grundprinzipien der Funktion von Organen und Geweben. Das Wissen der Physiologie erschlieAt sich somit A1/4ber die ZusammenhAnge mit den Akologischen Parametern Sauerstoff, Nahrung und Energie, Temperatur und Wasser -- und das aus einer Hand. Knut Schmidt-Nielsen ist emeritierter Professor fA1/4r Tierphysiologie an der Duke University in Durham. Er ist Mitglied der National Academy of Sciences und erhielt 1992 den International Prize for Biology, das japanische A"quivalent des Nobel-Preises.

It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
