Campbell Essential Biology with Physiology / Edition 4

by Eric J. Simon, Jean L. Dickey, Jane B. Reece

Overview

For non-majors biology courses.

Develop and Practice Science Literacy Skills

Teach students to view their world using scientific reasoning with Campbell Essential Biology. The authors’ approach equips your students to become better informed citizens, relate concepts from class to their everyday lives, and understand and apply real data, making biology relevant and meaningful to their world and futures.

The new edition incorporates instructor feedback on what key skills to highlight in new Process of Science essays and uses striking infographic figures in conveying real data to help students see and better understand how science actually works. New author-narrated Figure Walkthrough Videos appear in each chapter and guide students through key biology concepts and processes.

New topics in Why It Matters inspire curiosity and provide real-world examples to convey why abstract concepts like cell respiration or photosynthesis matter to students. This edition’s unmatched offering of author-created media supports students in the toughest topics.

Also available with Mastering Biology or as an easy-to-use, standalone Pearson eText

About the Author

ERIC J. SIMON is a professor in the Department of Biology and Health Science at New England College (Henniker, New Hampshire). He teaches introductory biology to science majors and nonscience majors, as well as upper-level courses in tropical marine biology and careers in science. Dr. Simon received a B.A. in biology and computer science, an M.A. in biology from Wesleyan University, and a Ph.D. in biochemistry from Harvard University. His research focuses on innovative ways to use technology to increase active learning in the science classroom, particularly for nonscience majors. Dr. Simon is also the author of the introductory biology textbook Biology: The Core, 2nd Edition, and a coauthor of Campbell Biology: Concepts & Connections, 9th Edition.

JEAN L. DICKEY is Professor Emerita of Biological Sciences at Clemson University (Clemson, South Carolina). After receiving her B.S. in biology from Kent State University, she went on to earn a Ph.D. in ecology and evolution from Purdue University. In 1984, Dr. Dickey joined the faculty at Clemson, where she devoted her career to teaching biology to nonscience majors in a variety of courses. In addition to creating content-based instructional materials, she developed many activities to engage lecture and laboratory students in discussion, critical thinking, and writing, and implemented an investigative laboratory curriculum in general biology. Dr. Dickey is the author of Laboratory Investigations for Biology, 2nd Edition, and is a coauthor of Campbell Biology: Concepts & Connections, 9th Edition.

JANE B. REECE was Neil Campbell’s longtime collaborator and a founding author of Campbell Essential Biology and Campbell Essential Biology with Physiology. Her education includes an A.B. in biology from Harvard University (where she was initially a philosophy major), an M.S. in microbiology from Rutgers University, and a Ph.D. in bacteriology from the University of California, Berkeley. At UC Berkeley, and later as a postdoctoral fellow in genetics at Stanford University, her research focused on genetic recombination in bacteria. Dr. Reece taught biology at Middlesex County College (New Jersey) and Queensborough Community College (New York). Dr. Reece’s publishing career began in 1978 when she joined the editorial staff of Benjamin Cummings, and since then, she played a major role in a number of successful textbooks. She was the lead author of Campbell Biology Editions 8—10 and a founding author of Campbell Biology: Concepts & Connections.

NEIL A. CAMPBELL (1946—2004) combined the inquiring nature of a research scientist with the soul of a caring teacher. Over his 30 years of teaching introductory biology to both science majors and nonscience majors, many thousands of students had the opportunity to learn from him and be stimulated by his enthusiasm for the study of life. He is greatly missed by his many friends in the biology community. His coauthors remain inspired by his visionary dedication to education and are committed to searching for ever better ways to engage students in the wonders of biology.
