This brief and specialized book was designed for general non-major biology courses and includes population ecology, communities, ecosystems, biosphere, human impact on the biosphere, and animal behavior. ECOLOGY AND BEHAVIOR covers Unit II form BIOLOGY: THE UNITY AND DIVERSITY OF LIFE, Tenth Edition.Research has given us a better understanding of the interconnectedness of molecular biology, structure, function, and evolution. In this Tenth edition, Starr and Taggart take that important connection out of the research realm and actually interweave these insights into the text. These unifying biological concepts encourage student understanding instead of memorization. With this background, students are better prepared to understand the power of comparative molecular studies in clarifying evolutionary relationships. The accompanying improvements in the media package meet the high standards instructors and students have come to expect from the Starr and Taggart media package. Students autom
