This engaging, conversational book presents a comprehensive overview of all aspects of ecology, including evolution, ecosystems, theory, practical applications, plants, and animals. Ecology and Field Biology, Fifth Edition features major shifts in the presentation of topics: two chapters on soil have been incorporated into one, while other various topics, such as acid deposition and global change, have been integrated into appropriate chapters. New issues discussed in this fifth edition include the importance of statistical power tests in ecological studies, the effects of impoundments on river ecology, intraguild predation, and more. Also featured in this edition are the addition of new pedagogical aids, a four-color design, and an entirely rewritten chapter on ecological experimentation and models.
