An 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. Sustainability is the integrating theme and co-authors G. Tyler Miller and Scott Spoolman inspire students to take a positive approach toward finding and implementing useful environmental solutions in their own lives and in their careers. Updated with new information, art, and 'Good News' examples, the text engages and motivates students with vivid case studies and hands-on quantitative exercises. The concept-centered approach transforms complex environmental topics and issues into key concepts that students will understand and remember.
