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.

Plant-animal interactions have become a focus of ecological research, with the processes of herbivory being of special interest. This volume examines the interactions of leaf-cutting ants with the rainforest vegetation on Barro Colorado Islands in Central America. It is the synthesis of field research on multiple scales extending over a period of several years. This work can serve as a model study summarizing and extending knowledge about herbivorous insect-plant relationships, and the resulting consequences on structural and functional features of tropical ecosystems. The text is an invaluable reference for researchers and land managers working in the fields of plant-animal interactions, herbivory, community ecology and biodiversity.
