Physiological Ecology: How Animals Process Energy, Nutrients, and Toxins

Description

Unlocking the puzzle of how animals behave and how they interact with their environments is impossible without understanding the physiological processes that determine their use of food resources. But long overdue is a user-friendly introduction to the subject that systematically bridges the gap between physiology and ecology. Ecologists--for whom such knowledge can help clarify the consequences of global climate change, the biodiversity crisis, and pollution--often find themselves wading through an unwieldy, technically top-heavy literature. Here, William Karasov and Carlos Martinez del Rio present the first accessible and authoritative one-volume overview of the physiological and biochemical principles that shape how animals procure energy and nutrients and free themselves of toxins--and how this relates to broader ecological phenomena. After introducing primary concepts, the authors review the chemical ecology of food, and then discuss how animals digest and process food. Their broad view includes symbioses and extends even to ecosystem phenomena such as ecological stochiometry and toxicant biomagnification. They introduce key methods and illustrate principles with wide-ranging vertebrate and invertebrate examples. Uniquely, they also link the physiological mechanisms of resource use with ecological phenomena such as how and why animals choose what they eat and how they participate in the exchange of energy and materials in their biological communities. Thoroughly up-to-date and pointing the way to future research, Physiological Ecology is an essential new source for upper-level undergraduate and graduate students-and an ideal synthesis for professionals. * The most accessible introduction to the physiological and biochemical principles that shape how animals use resources * Unique in linking the physiological mechanisms of resource use with ecological phenomena * An essential resource for upper-level undergraduate and graduate students * An ideal overview for researchers

William H. Karasov is professor of wildlife ecology at the University of Wisconsin-Madison. Carlos Martinez del Rio is professor of zoology and physiology at the University of Wyoming, Laramie.

"This extraordinary book by Karasov and Martinez del Rio integrates a wealth of research about how animals select, consume, and process food. The authors treat topics ranging from energy budgets, food chemistry, the structure and function of digestive systems, postabsorptive nutrient processing, and chemical ecology to feeding behavior, growth, production, and reproduction...Accessibly written, with clear, informative graphs and line drawings."--P.E. Hertz, Choice "This is an excellent textbook for undergraduate--and graduate-level courses, and is recommended for researchers who are interested in an up-to-date overview of this field."--Raymond Barbehenn, Quarterly Review of Biology "A big topic demands a big book, with some big thinkers behind it. When I agreed to review this book, I knew, given the authors, that I would see some big thinking, but the size of their effort took me by surprise. Physiological Ecology (all 744 pages, 2.7 liters, and 1.9 kilograms of it!) is a comprehensive yet surprisingly accessible treatment of a topic that is the linchpin for biologists of many stripes... So if animals and food webs are central to your interests, you should read this book."--James J. Eiser, BioScience "The authors can be very proud of their accomplishments in this book because their text deals with the general problem 'how animals process energy, nutrients, and toxins' in a very detailed, balanced, clearly written, informatively illustrated--in short, in an excellent way! One does not have to be a prophet to state that this book is destined to become a classic; it will become a widespread, often consulted and continually cited source of reference."--Peter Langer, Mammalian Biology
