All animals face the possibility of food limitation and ultimately starvation-induced mortality. This book summarizes state of the art of starvation biology from the ecological causes of food limitation to the physiological and evolutionary consequences of prolonged fasting. It is written for an audience with an understanding of general principles in animal physiology, yet offers a level of analysis and interpretation that will engage seasoned scientists. Each chapter is written by active researchers in the field of comparative physiology and draws on the primary literature of starvation both in nature and the laboratory. The chapters are organized among broad taxonomic categories, such as protists, arthropods, fishes, reptiles, birds, and flying, aquatic, and terrestrial mammals including humans; particularly well-studied animal models, e.g. endotherms are further organized by experimental approaches, such as analyses of blood metabolites, stable isotopes, thermobiology, and modeling of body composition.

This truly comparative text takes a fundamental, biophysical approach toward animal physiology. Students majoring in zoology, biology, or premedicine will study animals ranging from simple invertebrates and protozoans to complex multicellular invertebrates and vertebrates. Emphasis on evolution shows the progressive changes, modifications, and developments of physiological systems from simple to complex animals. Comparisons show the similarities and differences in how animals function, but stress fundamentally similar adaptations in very different animals.

This book describes a novel and unique approach to the treatment of human diseases based on the study of natural animal models. A natural animal model is defined as an animal group or species that possesses a set of biochemical/physiological characteristics which are natural and adaptive for that animal, but are quite abnormal for humans. For example, how is it that birds can tolerate blood glucose concentrations which in humans are associated with diabetes. The natural animal model is living proof that a biological answer to this question is available. By studying natural animal models, we can gain valuable insights into the treatment of various human clinical disorders. Covering a wide range of disorders, this book describes in detail how medical scientists can take advantage of all the “research” that nature has already performed over billions of years in biological problem solving through extensive animal design testing and selection./a

As far as we are aware, this is the first attempt to cover the com parative physiology of the pancreatic islets in a monograph. The topics discussed would probably have sufficed to fill about half a dozen monographs, a matter that becomes obvious from a look at the Contents. Hence, we have tried to present the ma terial more in the form of a digest, to emphasize evolutionary perspectives, to point out critical issues, and to identify challenging topics for future research. This approach required an arbitrary reduction of the num ber of references, and we therefore join the chorus of recent authors who beg their colleagues for understanding if some of their publications do not appear in the bibliography. Keeping up with the current literature was like fighting one of those monsters that grow a couple of new heads for each one that is cut off. Nevertheless, we hope that we have covered most of the key publications up to the autumn of 1986. We gratefully acknowledge the advice of many colleagues, and in particular the invaluable criticisms of Robert L. Hazelwood and Erika Plisetskaya. Special thanks are due to the series editor, Donald S. Farner, for his patience and guidance, both of which were fresh proof of his legendary diplomatic skills. Finally, we wish to thank Dr. D. Czeschlik and his staff at the Springer Verlag for their patience and support. Philadelphia, PA AUGUST EpPLE Greenville, NC JACK E. BRINN September 1987 v Contents Chapter 1.

This book discusses the structural and functional characteristics of the digestive system and how these vary among vertebrates.

Comparative developmental physiology is a growing discipline examining a diversity of organisms as they transform from single cells to mature, reproductive individuals. This collection of original, innovative essays emerged from a Roundtable on Comparative Developmental Physiology held in Glen Rose, Texas in the summer of 2002. This meeting brought together investigators studying the physiology of developing animals in an effort to identify the field's potential contributions to biology. The participants honed in on common emerging themes and future goals, which are reflected in the chapters within. The nascent community of comparative developmental physiologists was challenged to amplify the power of data collection and tool development by focusing on a few select model organisms, while still employing the power of the broader, more traditional comparative approach. Evolution has provided comparative developmental physiologists with remarkable biological diversity, which they have used to investigate a broad range of questions critical for understanding how life works. This goes beyond the basic nuts and bolts of cellular mechanisms to the functional whole, from the mechanistic level to behavior within and between organisms. The union of developmental biology with the breadth of comparative physiology holds much promise for a deeper understanding of evolutionary processes.
