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...

"This book fills a major gap in the ecological and physiological literature in the most delightful way. An exciting journey into the wondrous mechanical world behind the great diversity of animals on earth, it is an exhaustive overview of everything to do with resource processing and use in animals. From page to page it demonstrates the seamless connection between ecology and physiology. The writing was a joy to read; the authors are in command of the subject and write lucidly about it."—Theunis Piersma, University of Groningen and Royal Netherlands Institute for Sea Research"Physiological Ecology addresses an important and intriguing topic that has not been adequately summarized previously; there is no corresponding book that discusses resource use at the level presented here. The authors do a masterful and authoritative job of covering both the basics and the details. The numerous and diverse examples and case studies are great, for they illustrate both the concepts and the authors' obvious pleasure in the underlying natural history—part of the fun of this sort of biology."—Joel Kingsolver, University of North Carolina, Chapel Hill P.E. Hertz - Choice 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.

\ Choice\ - P.E. Hertz\ 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.\ \ \ \ \ Quarterly Review of Biology\ - Raymond Barbehenn\ 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.\ \ \ BioScience\ - James J. Eiser\ 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.\ \ \ \ \ Mammalian Biology\ - Peter Langer\ 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.\ \ \ \ \ ChoiceThis extraordinary book by Karasov and Martinez del Rio integrates a wealth of research about how animals select, consume, and process food.
