A study of comparative physiology that explains the ways in which specific bodily systems function in different species.
How do dolphins catch fish in murky water? Why do moths drink from puddles? How do birds' eggs breathe? How do animals work? In this revised and updated edition of the acclaimed text Animal Physiology, the answers are revealed. In clear and stimulating style, Knut Schmidt-Nielsen introduces and develops the fundamental principles of animal physiology according to major environmental features - oxygen, food and energy, temperature, and water. The structure of the book is unchanged from the previous edition, but every chapter has been updated to take into account recent developments, with numerous new references and figures. Animal Physiology is suitable as a text for undergraduate and beginning graduate courses in physiology. As with previous editions, students, teachers as well as researchers will find this book a valuable and enjoyable companion to course work and research.
This book attempts to dispel the widely held notion that 'primitive' animals are less advanced or less complex than the 'non-primitive'.
Originally published in 1982, this book was designed to supplement Knut Schmidt-Nielsen's Animal Physiology. Using Schmidt-Nielsen's comparative approach to the study of animal form function, the text pursues in greater detail topics introduced in Animal Physiology. Like the textbook, the Companion is organised according to major environmental features: oxygen, food and energy, temperature, and water, concluding with a section on movement and structure. The papers brought together in this volume were presented in July 1980 to honour Smith-Nielsen's sixty-fifth birthday, at the Fifth International Conference on Comparative Physiology, held in Sandbjerg, Denmark.
This book is about the importance of animal size. We tend to think of animal function in chemical terms and talk of water, salts, proteins, enzymes, oxygen, energy, and so on. We should not forget, however, that physical laws are equally important, for they determine rates of diffusion and heat transfer, transfer of force and momentum, the strength of structures, the dynamics of locomotion, and other aspects of the functioning of animal bodies. Physical laws provide possibilities and opportunities for an organism, yet they also impose constraints, setting limits to what is physically possible. This book aims to give an understanding of these rules because of their profound implications when we deal with animals of widely different size and scale. The reader will find that the book raises many questions. Remarkable and puzzling information makes it read a little like a detective story, but the last chapter, instead of giving the final solution, neither answers all questions nor provides one great unifying principle.
"It has been said that the primary function of schools is to impart enough facts to make children stop asking questions. Those with whom the schools do not succeed become scientists." So begins Knut Schmidt-Nielsen in his autobiography The Camel's Nose, a fascinating reflection on his life and more than forty years of studies and adventures in locations ranging from the Sahara Desert to the Arctic Circle.One of the world's most prominent animal physiologists, Schmidt-Nielsen has throughout his career sought answers to seemingly simple questions: How can camels go for days without drinking? Do marine birds drink seawater? Why don't penguins' feet freeze? How do animals find food and water in ...

Advances in Physiological Sciences, Volume 20: Advances in Animal and Comparative Physiology covers the proceedings of the symposia of the 28th International Congress of Physiology. The book discusses several studies that tackle issues about the advances in animal and comparative study. The text is comprised of 61 chapters in which Chapter 4 and the succeeding chapters are grouped into eight parts based on the topic of the studies. The opening chapter explains sensory modalities beyond human perception, while Chapter 2 discusses trends in the physiology of domesticated animals. Chapter 3 reviews muscles in living animals, which is followed by topics grouped into parts. The first part deals w...
To newly minted biologist James Estes, the sea otters he was studying in the leafy kelp forests off the coast of Alaska appeared to have an unbalanced relationship with their greater environment. Gorging themselves on the sea urchins that grazed among the kelp, these small charismatic mammals seemed to give little back in return. But as Estes dug deeper, he unearthed a far more complex relationship between the otter and its underwater environment, discovering that otters play a critical role in driving positive ecosystem dynamics. While teasing out the connective threads, he began to question our assumptions about ecological relationships. These questions would ultimately inspire a lifelong ...
