Each volume in this series describes the biology and natural history of a particular species. While the ideas presented may be sophisticated, the tone is anecdotal and very readable. The series appeals to general naturalists as well as to trained biologists.The Chocolate Tree is a rich confection of cultural and natural history, archaeological evidence, botanical research, environmental activism, and the lush descriptions of a contemporary adventurer encountering tropical wonders as Allen M. Young recounts more than a dozen years of ecological field work in and around cacao plantations in Costa Rica.
