Campbell Biology in Focus, 4th Edition, AP Edition © 2025

• New: Interactive reading assignments let students read, watch and practice in one seamless experience. Instructors can now assign the eTextbook along with curated content including multimedia and practice questions for auto-grading.
• New: Active reading guides are worksheets that provide students with self-assessment activities to complete as they read a chapter and can be downloaded from the Study Area.
• New: Data modeling activities feature 10 activities that give students practice with quantitative reasoning skills and include simulations that allow students to manipulate variables, examine data, and draw conclusions. The autogradable simulations are embedded in Mastering tutorials.
• New: CheckPoint interactive questions are embedded at point-of-use in the Pearson+ eTextbook and can be assigned in the mastering item library. Questions challenge student misconceptions with an integrated series of questions and answer-specific feedback.
• Pearson^® Interactive Labs are structured around the process of science and feature real-world scenarios and guided feedback so students can make and learn from their mistakes.
• Study skills dynamic study modules are student-centered and address test taking, studying vs. learning, time management, resources, accountability, reading and taking notes.

• New: CheckPoint interactive questions are embedded at point-of-use in the P+ eTextbook and can be assigned in the mastering item library. Questions challenge student misconceptions with an integrated series of questions and answer-specific feedback.
• New: Topical content covers SARS-CoV-2, the COVID-19 pandemic, microplastics pollution and climate modeling, global atmospheric and oceanic changes, stem cell research, genomics, cancer genetics, hominin fossil discoveries and genomic findings.
• Interactive visual activities guide students in navigating complex figures as they interact with the textbook’s powerful art program, view embedded video clips, and gauge understanding with self-check questions.
• Figure walkthrough videos guide students through key figures, narrated explanations, figure markups, and questions to reinforce important points and encourage active participation.
• Videos and animations that have been carefully chosen and edited bring biology to life.

Lisa A. Urry (Units 1 and 2) is Professor of Biology and Co-Chair of the Biology Department at Mills College at Northeastern University in Oakland, California. After earning a B.A. at Tufts University, she completed her Ph.D. at the Massachusetts Institute of Technology (MIT). Lisa has conducted research on gene expression during embryonic and larval development in sea urchins. Deeply committed to promoting opportunities in science for women and underrepresented groups, she has taught courses ranging from introductory and developmental biology to an immersive course on the U.S./Mexico border.

Michael L. Cain (Units 3, 4, and 7) is an ecologist and evolutionary biologist who is now writing full- time. Michael earned an A.B. from Bowdoin College, an M.Sc. from Brown University, and a Ph.D. from Cornell University. As a faculty member at New Mexico State University, he taught introductory biology, ecology, evolution, botany, and conservation biology. Michael is the author of dozens of scientific papers on topics that include foraging behavior in insects and plants, long-distance seed dispersal, and speciation in crickets. He is also a coauthor of an ecology textbook.

Peter V. Minorsky (Chapter 1 and Unit 5) is Professor of Biology at Mercy University in New York, where he teaches introductory biology, ecology, and botany. He received his A.B. from Vassar College and his Ph.D. from Cornell University. Peter taught at Kenyon College, Union College, Western Connecticut State University, and Vassar College. His research interests concern how plants sense environmental change. Peter received the 2008 Award for Teaching Excellence at Mercy College.

Kerry L. Hull (Unit 6) is the Dean of Science, a Professor in the Department of Biology and Biochemistry, and the Associate Vice-Principal for Research at Bishop’s University in Quebec, Canada. She holds a B.Sc. in Biology and a Ph.D. in Physiology (Endocrinology), both from the University of Alberta (Canada). She teaches physiology and anatomy courses to undergraduates, using guided inquiry and case studies as her primary teaching approaches. A comparative endocrinologist by training, her current research focuses on the development and implementation of active learning strategies in anatomy and physiology courses.

Rebecca B. Orr (Active Learning Modules, eText Media Integration) is Professor of Biology at Collin College in Plano, Texas, where she teaches introductory biology. She earned her B.S. from Texas A&M University and her Ph.D. from University of Texas Southwestern Medical Center at Dallas. Rebecca has a passion for investigating strategies that result in more effective learning and retention, and she is a certified Team-Based Learning Collaborative Trainer Consultant. She enjoys focusing on the creation of learning opportunities that both engage and challenge students.
