This book examines one of the most important and complex of the world's tropical rainforest regions: the greater Panama Canal Watershed. The Rio Chagres is the primary water source for operating the Canal, and supplies potable water for municipal use and electricity generation, but science has left this important national resource largely unstudied. The text promotes understanding of the physical and ecological components of an isolated and largely pristine tropical rainforest.

The Panama Canal's untold history—from the Panamanian point of view. Sleuth and scholar Marixa Lasso recounts how the canal’s American builders displaced 40,000 residents and erased entire towns in the guise of bringing modernity to the tropics. The Panama Canal set a new course for the modern development of Central America. Cutting a convenient path from the Atlantic to the Pacific oceans, it hastened the currents of trade and migration that were already reshaping the Western hemisphere. Yet the waterway was built at considerable cost to a way of life that had characterized the region for centuries. In Erased, Marixa Lasso recovers the history of the Panamanian cities and towns that once formed the backbone of the republic. Drawing on vast and previously untapped archival sources and personal recollections, Lasso describes the canal’s displacement of peasants, homeowners, and shop owners, and chronicles the destruction of a centuries-old commercial culture and environment. On completion of the canal, the United States engineered a tropical idyll to replace the lost cities and towns—a space miraculously cleansed of poverty, unemployment, and people—which served as a convenient backdrop to the manicured suburbs built exclusively for Americans. By restoring the sounds, sights, and stories of a world wiped clean by U.S. commerce and political ambition, Lasso compellingly pushes back against a triumphalist narrative that erases the contribution of Latin America to its own history.

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.
