This book is the product of a great many contributors. First and foremost, the editors are grateful to Ms. Amy Skoczlas for her tireless devotion and leadership as our Assistant Editor. The editors would also like to thank the outstanding group of contributing authors who provided excellent chapters that are the main subject of the book— the authors gave liberally of their time and shared with us and the readers their enthusiasm and experience with complex issues. In addition, the editors would like to thank Robin Bell and Debra Gordon for their critical support in development of the book prospectus and our initial discussions with Oxford University Press. We would also like to thank many Conservation International staff including Lena McDowall, Sterling Zumbrunn, Tanya Tarar, Petra MacGowan, Amy Rosenfeld, Cheri Sugal, Jeff Mastracchio, and Aaron Bruner for their help. Finally, we would like to thank our editor, Joyce Berry at Oxford University Press, for her enthusiasm, encouragement, and flexibility throughout the process that has led to publication of this volume. Ian thanks his family for their encouragement and dedicates this effort to the memory of his grandfather, Dr. George H. A. Clowes Jr., for his scholarly leadership and great love of nature. Glenn would like to thank his wife, Lisa Prickett, for her support and encouragement of this effort, and his father, Gordon Prickett, for his valuable insights as both a mining engineer and environmentalist.
