The book is committed to a comparative approach throughout. Whereas mammalian physiology is consistently treated in depth, emphasis is also given to the other vertebrate groups, arthropods, and molluscs. Concepts and integrative themes are emphasized while giving students the specifics they need.

The whole animal is the principal focus of this book. The book's extensive coverage of genomics and cellular-molecular biology is therefore carefully linked to whole-animal biology. With this edition, coverage of physiologically relevant genomics has been greatly expanded. The subject matter of animal physiology is also linked to topics in human affairs, such as athletic training and global warming. Always, the central organizing principle for the array of topics presented is to understand whole animals in the environments where they live.

Complex principles are developed clearly using classroom-tested pedagogy, often with carefully designed conceptual illustrations. Concepts from chemistry, physics, and mathematics are explained so that the book will be accessible to science students at the sophomore or higher level. Pedagogical aids include embedded summaries throughout chapters, study questions (with online answers), partially annotated reference lists, an extensive glossary, ten appendices (covering logarithms, phylogenetically independent contrasts, basic physics terms, etc.), and an upgraded index. Carefully worded balloons are used extensively to guide students through the interpretation of figures. For all three authors, teaching physiology to undergraduate students has been a lifelong priority.

RESOURCES

For Students

The Animal Physiology Companion Website includes content that expands on the coverage in the textbook as well as study and review resources for students.

*Chapter Outlines & Summaries provide quick overviews and reviews of each chapter
*Box Extensions expand on topics introduced in the textbook and cover important additional conceptual material
*Online Quizzes cover key material in each chapter. These can be assigned by the instructor or used as self-quizzes.
*Flashcards help students learn and review the many new terms introduced in the textbook
*Glossary

For Instructors (available to qualified adopters)

The Animal Physiology, Fourth Edition Instructor's Resource Library (IRL) contains a wealth of resources for use in lecture development and assessment. Contents include:

Presentation Resources
*Figures & Tables: All of the textbook's figures (both line art and photographs) are provided as JPEG files at two sizes: high-resolution (excellent for use in PowerPoint) and low-resolution (ideal for web pages and other uses). All the artwork has been reformatted and optimized for exceptional image quality when projected in class.
*Unlabeled Figures: Unlabeled versions of all figures are provided

PowerPoint Presentations:
*Figures & Tables: Includes all the figures and tables from the chapter, making it easy to insert any figure into an existing presentation
*Layered Art PowerPoints: Selected key figures throughout the textbook are prepared as step-by-step and animated presentations that build the figure one piece at a time

The Test Bank consists of a broad range of questions covering the key facts and concepts in each chapter. Both multiple-choice and short-answer questions are provided. The Test Bank also includes the Companion Website online quiz questions.

The Computerized Test Bank is provided in the Diploma exam-creation program (software included). Diploma makes it easy to assemble quizzes and exams from any combination of publisher-provided questions and instructor-created questions. In addition, quizzes and exams can be exported to many different course management systems, such as Blackboard, WebCT, and Moodle.
