Book excerpt: G. Tyler Miller's worldwide bestsellers have evolved right along with the changing needs of your diverse student population. Focused specifically on energizing and engaging all your students, Miller and new coauthor Scott Spoolman have been at work scrutinizing every line-enhancing, clarifying, and streamlining to reduce word density as well as updating with the very latest environmental news and research. The resulting texts are shorter, clearer, and so engaging that your students will actually want to read their assignments. The ideal alternative to ecology texts that tend to be too difficult for non-majors, this succinct 11-chapter, full-color textbook covers scientific principles and concepts, ecosystems, evolution, biodiversity, population ecology, and more.
