Ecology: Concepts and Applications, 8th edition by Molles and Sher places great emphasis on helping students grasp the main concepts of ecology while keeping the presentation more applied than theoretical.

Its unique organization of focusing only on several key concepts in each chapter sets it apart from other ecology texts. Download the PDF here Click here
