Book Description
Big-Leaf Mahogany is the most important commercial timber species of the tropics. Current debate concerning whether to protect it as an endangered species has been hampered by the lack of complete, definitive scientific documentation. This book reports on vital research on the ecology of big-leaf mahogany, including genetic variations, regeneration, natural distribution patterns and the silvicutural and trade implications for the tree.

Book Description
The Amazon is not what it seems. As Hugh Raffles shows us in this captivating and innovative book, the world's last great wilderness has been transformed again and again by human activity. In Amazonia brings to life an Amazon whose allure and reality lie as much, or more, in what people have made of it as in what nature has wrought. It casts new light on centuries of encounter while describing the dramatic remaking of a sweeping landscape by residents of one small community in the Brazilian Amazon. Combining richly textured ethnographic research and lively historical analysis, Raffles weaves a fascinating story that changes our understanding of this region and challenges us to rethink what we mean by "nature." Raffles draws from a wide range of material to demonstrate--in contrast to the tendency to downplay human agency in the Amazon--that the region is an outcome of the intimately intertwined histories of humans and nonhumans. He moves between a detailed narrative that analyzes the production of scientific knowledge about Amazonia over the centuries and an absorbing account of the extraordinary transformations to the fluvial landscape carried out over the past forty years by the inhabitants of Igarapé Guariba, four hours downstream from the nearest city. Engagingly written, theoretically inventive, and vividly illustrated, the book introduces a diverse range of characters--from sixteenth-century explorers and their native rivals to nineteenth-century naturalists and contemporary ecologists, logging company executives, and river-traders. A natural history of a different kind, In Amazonia shows how humans, animals, rivers, and forests all participate in the making of a region that remains today at the center of debates in environmental politics.

Book Description
This paper disaggregates the term "biodiversity" into components (landscapes, ecosystems, communities, species/populations, and genes) and attributes (structure, composition, and function). It then disaggrgates "logging" by detailing the vast range of activities subsumed under the term including variation of logging intensities, logging methods, collateral damage, and silvicultural approaches. Using the richness present in both terms, a framework for considering the impacts of logging and other forest management activities on the various components and attributes of biodiversity is presented. This framework is, in turn, used to evaluate the extensive literature covering different studies of logging in tropical forests. This paper does not conclude with uncritical support for sustainable forest managmement of timber as a conservation strategy. Such an endorsement is unwarranted given widespread illegal logging in the tropics, widespread frontier logging and logging of areas of high priority for biodiversity protection, the persistence of poor logging practices despite substantial efforts in research and training, and the generally slow rate at which most loggers are transforming themselves from timber exploiters into forest managers. Rather the authors assert, from a biodiversity maintenance perspective, that natural forest management is preferable to virtually all land-use practices other than complete protection.
