Description of ANIMAL PHYSIOLOGY Adaptation and environment

The reason for the second edition of a book should be to make it better. This may be done by improving existing material and by updating the information it contains, and I have tried to do both. Every chapter is revised, important new information is added, and some chapters cover their subjects in greater depth than in the first edition. As before, I consider that the understanding of principles is more important than the mere accumulation of facts that can smother in boredom the curiosity of interested young people. I have selected new material with this in mind.
Those readers who teach physiology may wish to see a listing of changes and improvements. The respiration chapters contain new material on fish respiration, on lungless salamanders, and on the oxygen supply to birds' eggs. The chapters on blood and circulation are expanded and clarified. The chapter on food and feeding contains new material on marine waxes and their importance in the food chain, on nitrogen fixation in termites and in corals, and a substantial expansion of the discussion of noxious plant compounds and chemical defenses. In the chapter on metabolism, new material includes discussions of the oxygen minimum layer in the ocean and of the effects of high pressure and high altitude. The treatment of problems of scaling and body size is completely revised. The chapters on temperature and heart problems contain new material on thermal tolerance and heat death. New concepts on the biological importance of fever are discussed, and recent research on the temperature regulation of birds and bees is included. The chapters on osmoregulation and excretion have been clarified, and recent changes in our concepts of how urine is concentrated in the mammalian kidney are clearly explained.
The three chapters toward the end of the book, those on muscle, nerve, and hormones, are completely revised and much new material is added. The expanded treatment ranges from new concepts of ameboid movement and the function of flagella to the molecular events in muscle contraction. Animal locomotion and biomechanics are given a prominent place, for moving about is an important characteristic of living animals.
The material on sensory perception is updated, especially in regard to electric and magnetic stimuli and the function of the lateral line of fishes. The explanation of the nature of nerve impulses and action potentials is completely rewritten and expanded to meet current requirements. The last chapter, on physiological integration, has also been thoroughly revised. The close connection between the central nervous system and endocrine function, which was stressed in the first edition, is clarified through discussions of exciting new developments in neuroendocrine function.
Instead of an enumeration of nearly endless numbers of hormones - to be memorized by students with retentive brains - there are clear tables that outline the important principles of modern endocrinology. As in the first edition, some essential background material that already should be known to the students is placed in appendixes, not because it is considered peripheral, but because it is so important that it must be available to those who have forgotten and need a concise restatement of basic facts. The International System of Units (the SI system) is clearly and accurately presented in Appendix A (as it was in the first edition). In addition, the inevitable transition to the common use of SI units is helped by the side-by-side use in the text of traditional units and the corresponding SI units. Two important fields, vitamins, and reproduction are treated very lightly or not at all. The simple reason is that much of this material is already familiar.
Lists of vitamins and their deficiency symptoms are of little use; they are found in books the student has met in courses on health, home economics, and introductory biology. A deeper understanding of the metabolic roles of vitamins requires a background in biochemistry that is beyond the scope of this book. The basics of human reproduction should already be familiar, and animal reproduction is a vast field that includes so much morphology and developmental biology that it is best treated as a separate subject. I hope that the changes increase the usefulness of the book and that both students and colleagues will let me know what I should have done better.
