This collection of 12 ethnobiological papers compiled in honor of ethnobiologist Amadeo Rea, plus an essay by Rea himself, reflect the depth and breadth of the field of ethnobiology. Each chapter explores some aspect of the rich and complex relationship of indigenous and other subsistence-based peoples with their biological worlds. The volume's chapters are authored by some of today's leaders in ethnobiology and cover a range of ethnobotanical and ethnozoological topics from the distant past to the immediate present. Using a variety of methods from interviews with knowledge holders to cutting edge quantitative linguistic analyses, the papers cover broadly relevant themes such as conservation and the linkages between biological diversity, cultural diversity, and their resilience. This book is the first volume in the Contributions in Ethnobiology series.
