This book attempts to dispel the widely held notion that 'primitive' animals are less advanced or less complex than the 'non-primitive'.

The XXX Congress of the International Union of Physiological Sciences took place in Vancouver, Canada, in July 1986; and this Volume contains a selection of the Review Lectures which formed part of the Congress programme. They cover most of the areas of contemporary physiology and were presented by distinguished scientists from many parts of the world. An innovation at this Congress was the inclusion in the programme of a number of lectures devoted to historical subjects. These lectures attracted large audiences at the meetings, and three of them also appear in this book. Finally, the Plenary Lectures which formed part of the opening and closing ceremonies and which deal with some aspects of Canadian physiological history, find a place here as well. The Editors are grateful to all of the authors who provided the manuscripts which go to make up this book, and to John Donald for his invaluable assistance in the preparation of the final text; as well of course to all of the contributors whose participation made the Congress the success which it was. It is hoped that this Volume will provide a useful memento of the event.

This book is designed to meet the needs of students studying for Veterinary Nursing and related fields.. It may also be useful for anyone interested in learning about animal anatomy and physiology.. It is intended for use by students with little previous biological knowledge. The book has been divided into 16 chapters covering fundamental concepts like organic chemistry, body organization , the cell and then the systems of the body. Within each chapter are lists of Websites that provide additional information including animations.

Abstract: This book discusses the factors which affect the heat produced by animals and man and the ways in which the energy of the organic components of their diets are used to support growth and reproduction. The general thermodynamic principles are considered in addition to the physical principles related to heat loss by radiation, convection, conduction and evaporation of water. Major parts of the book deal with the minimal or basal production of heat, with the heat produced during muscular work and as a result of physiological reactions to the climatic environment. The test is intended for undergraduates and postgraduates who are studying energy metabolism in the context of zoology, agriculture, ecology, or medicine.

Biochemical, physiological and morphological aspects of mammalian digestive systems.

This one-semester text is designed for an upper-level majors course. Vertebrates features a unique emphasis on function and evolution of vertebrates, complete anatomical detail, and excellent pedagogy. Vertebrate groups are organized phylogenetically, and their systems discussed within such a context. Morphology is foremost, but the author has developed and integrated an understanding of function and evolution into the discussion of anatomy of the various systems.

As part of the preparation of the materials for this volume, the contributors attended a conference designed to explore the basic concept of symbiosis and its applicability to the study of parents and their offspring. Each participant was asked to focus not on the parental behavior of various species, but on parent and offspring as a symbiotic unit. The presentations were informal and the discussions intense. The chapters that follow were written many months after the conference and reflect the authors' efforts to integrate the comments and criticisms of their colleagues. Out of this amalgam, the present volume was shaped. We wish to thank the National Institute of Mental Health for supporting the conference (Grant MH 36276) and the University of Chicago for hosting it. The editors would also like to acknowledge the contributions of Dr. M. Lewis and Dr. J. Reinisch, who provided additional perspectives on the discussions held at the meeting. Special thanks are due Gary Schwartz for his thoughtful assistance throughout the course of this project. Lu Ann Homza has provided invaluable secretarial help. Leonard A.

How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods evolve from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the 500-million-year history of vertebrate life. And with the aid of new techniques and approaches across a range of fields—work spanning multiple levels of biological organization from DNA sequences to organs and the physiology and ecology of whole organisms—we are now beginning to unravel the confounding evolutionary mysteries contained in the structure, genes, and fossil record of every living species. This book gathers a diverse team of renowned scientists to capture the excitement of these new discoveries in a collection that is both accessible to students and an important contribution to the future of its field. Marshaling a range of disciplines—from paleobiology to phylogenetics, developmental biology, ecology, and evolutionary biology—the contributors attack particular transformations in the head and neck, trunk, appendages such as fins and limbs, and the whole body, as well as offer synthetic perspectives. Illustrated throughout, Great Transformations in Vertebrate Evolution not only reveals the true origins of whales with legs, fish with elbows, wrists, and necks, and feathered dinosaurs, but also the relevance to our lives today of these extraordinary narratives of change.
