The authors of this book are students at all five of the Claremont Colleges. The book is a work product of Biology 159: Natural Resources Management taught by Emil Morhardt in the Joint Science Department of Claremont McKenna, Pitzer, and Scripps Colleges. Each student picked a topic, did a full literature search, and selected ten papers written within the past year that exemplified the state of the science. Their task was to write journalistic summaries capturing the essence of the papers but eschewing technical terms to the extent possible—to become, in effect, science writers. The summaries were due weekly and were returned with editorial comments shortly thereafter. The chapters are compilations of the individual sum-maries with additional introductory and conclusionary material. The editor is Roberts Professor of Environmental Biology at Claremont McKenna, Pitzer, and Scripps colleges, and Director of The Roberts Environmental Center at Claremont McKenna College. He remembers how difficult it is to learn to write and appreciates the professionalism shown by these students.
