The introduction to genes, genomes, and gene expression in Units One and Two should help prepare students for these revisions. Chapter 18 includes a new section on nuclear architecture, which describes the organization of chromatin in the nucleus in relation to gene expression. The roles of various types of RNA molecules in regulation also receive special attention.
In the section on cancer, we describe how technical advances can contribute to personalized cancer treatments based on the molecular characteristics of an individual's tumor. Chapter 19 discusses the H1N1 flu pandemic. Chapter 20 includes advances in techniques for DNA sequencing and for obtaining induced pluripotent stem iPS cells. Finally, the heavily revised Chapter 21 describes what has been learned from the sequencing of many genomes, including those of a number of human individuals.
For this edition, we have continued to bolster our presentation of the vast evidence for evolution by adding new examples and figures that illustrate key conceptual points throughout the unit. For example, Chapter 22 now presents research data on adaptive evolution in soapberry bugs, fossil findings that shed light on the origins of cetaceans, and an Impact Figure on the rise of methicillin-resistant Staphylococcus aureus.
Chapter 23 examines gene flow and adaptation in songbird populations. Chapter 24 incorporates several new examples of speciation research, including reproductive isolation in mosquitofish, speciation in shrimp, and hybridization of bear species. Other changes strengthen the storyline of the unit, ensuring that the chapters flow smoothly and build to a clear overall picture of what evolution is and how it works.
For instance, new connections between Chapters 24 and 25 illustrate how differences in speciation and extinction rates shape the broad patterns in the history of life. One of our goals for the diversity unit was to expand the coverage of the scientific evidence underlying the evolutionary story told in the chapters.
So, for example, Chapter 27 now presents new findings on the evolutionary origin of bacterial flagella. An evogram is a diagram illustrating the multiple lines of evidence that support the hypothesis shown in an evolutionary tree. Examples include new material on global growth of photosynthetic protists Chapter 28 , endangered molluscs Chapter 33 , and the impact of a pathogenic chytrid fungus on amphibian population declines Chapters 31 and Plant biology is in a transitional phase; some professors prefer strong coverage of classical botany while others seek more in-depth coverage of the molecular biology of plants.
In developing the Ninth Edition, we have continued to balance the old and the new to provide students with a basic understanding of plant anatomy and function while highlighting dynamic areas of plant research and the many important connections between plants and other organisms.
One major revision goal was to provide more explicit discussion of the evolutionary aspects of plant biology, such as the coevolution of insects and animal pollinators Chapter Updates include new findings in plant development in Concept In revising this unit, we strove to introduce physiological systems through a comparative approach that underscores how adaptations are linked to shared physiological challenges.
In particular, we have highlighted the interrelationship of the endocrine and nervous systems at multiple points in the unit, helping students appreciate how these two forms of communication link tissues, organs, and individuals. Other revisions aim to keep students focused on fundamental concepts amid the details of complex systems. For example, many figures have been reconceived to emphasize key information, including new figures comparing single and double circulation Chapter 42 and examining the function of antigen receptors Chapter 43 , as well as new Exploring Figures on the vertebrate kidney Chapter 44 and the structure and function of the eye Chapter Throughout the unit, new state-of-the-art images and material on current and compelling topics—such as circadian rhythms Chapter 40 , novel strains of influenza Chapter 43 , the effects of climate change on animal reproductive cycles Chapter 46 , and advances in understanding brain plasticity and function Chapter 49 —will help engage students and encourage them to make connections beyond the text.
Our revision was informed by the fact that biologists are increasingly asked to apply their knowledge to help solve global problems, such as climate change, that already are profoundly affecting life on Earth. The organizational changes begin with the introductory chapter of the unit Chapter 52 , which includes a new Key Concept New content in Chapters 53 and 54 highlights factors that limit population growth, the ecological importance of disease, positive interactions among organisms, and biodiversity.
Chapter 55 now explores restoration ecology together with ecosystem ecology because successful restoration efforts depend on understanding ecosystem structure and function.

Reece, Berkeley, California Lisa A. Availability This title is out of print. The Key Concepts are presented at the beginning of the chapter to orient students to the main ideas of the chapter. The Overview and chapter opening question engage students and set the stage for the chapter content. Numbered Concept Heads remind students of the main ideas as they begin each section of the chapter and make it easy for instructors to assign selected sections.
Summary diagrams provide a visual review of the material and new Summary of Key Concepts Questions enable students to check their understanding of a key learning goal for each Key Concept. New Impact Figures motivate and inspire students by demonstrating the impact of biology research on their daily lives, the field of biology, and global problems. New Visual Organizers highlight the hierarchy of information in multipart figures to help students understand and study the material.
New to This Edition. Each Make Connections Question challenges students to move beyond memorization and gain a deeper understanding of biological principles by asking them to relate the content of a chapter to what they learned earlier in the course. Make Connections Questions are integrated into each chapter in selected Concept Checks, figure legends, Impact Figures, and in the end-of-chapter assessment section.
Every chapter has at least three Make Connections Questions. Impact Figures explore high-interest topics such as induced pluripotent stem cells and regenerative medicine Chapter 20 , the discovery of Tiktaalik Chapter 34 , and the use of forensic ecology to track elephant poaching Chapter Captivating visuals in Impact Figures engage students.
