New coauthor Anna Sher joins longtime author Richard Primack in creating a book that combines the readability of Primack's A Primer of Conservation Biology with the depth and coverage of his larger textbook, Essentials of Conservation Biology. The result is a book well suited for a wide range of undergraduate courses, as both a primary text for conservation biology courses and a supplement for ecological and environmental science courses. Using the chapter framework of the current Primer as a springboard, the authors have added three chapters focused on population biology conservation tools, restoration ecology, and the future of conservation. Sustainable development, ex situ conservation, and other key topics have been expanded and updated with hundreds of new examples, explanations, citations, and figures to enhance learning and excitement for the subject. Mining her experience teaching conservation biology with Dr. Primack's texts for over a decade, Dr. Sher fine-tunes the presentation of difficult concepts, particularly in economics and politics. Coverage of recent conservation biology events in the news--such as the poaching of Cecil the lion, the first papal encyclical on the environment, and the international Paris Accord on climate change--keeps the content fresh and current. The book's twelve chapters focus successively on biological diversity and its value; threats to biological diversity; conservation at the population and species levels; protecting, managing and restoring ecosystems; and sustainable development. Each chapter begins with general ideas and principles, beautifully illustrated in full color with diverse examples from the current literature. Chapters end with summaries, an annotated list of suggested readings, discussion questions, and extensive summary statements in the tex
