* I am grateful to the residents of the Ucayali for allowing me to conduct research in their villages and for answering all my questions. Sergio Gonzales provided invaluable assistance in the field, and Luis Collado Panduro helped gather additional evidence for this study. The Consejo Nacional de Ciencia y Tecnología‐México and the MacArthur, Ford, and Hewlett Foundations, as well as McGill University, provided funding for the research. I acknowledge the assistance of government officials from the Ministerio de Agricultura (Región Ucayali) and the logistical support of the Centro Internacional de Agricultura Tropical, the International Plant Genetic Resources Institute—Consorcio para el Desarrollo Sostenitable de Ucayali, and the Fundación por la Selva Viva. River‐level and seismic data were provided by the Dirección de Transporte Acuático—Ministerio de Transportes y Comunicaciones (Región Ucayali) and Dr. Hernando Tavera of the Instituto Geofísico del Perú, respectively. Anastassia Khouri, Joanna Hobbins, and Rosa Orlandini of the McGill University Library helped me to obtain the satellite imagery.
