Maraca: The Biodiversity and Environment of an Amazonian Rainforestby William Milliken
Synopses & Reviews
Few tropical ecosystems have been subjected to multi-disciplinary investigations as broad and exhaustive as those carried out on the Ilha de Marac?, a riverine island in the Brazilian Amazon. This diverse and remarkable ecological reserve, in Brazil?s northernmost Amazon state of Roraima, includes environments and habitats ranging from rainforests and semi-deciduous forests to natural savannas, lakes, rivers and palm swamps. These have been subjected to an in-depth international scientific study whose primary aim was to undertake one of the most detailed ecological surveys ever conducted in Amazonia. The results of this enormous body of research, involving the collaborative fieldwork of some 200 workers, span the reserve?s geology, geomorphology, botany, zoology, phenology, soils, limnology, ecology and historical human occupation. These have been carefully drawn together in this volume in such a manner as to provide not only a coherent and scholarly picture of an unique and fascinating environment, but also an important and enduring source of reference for a broad spectrum of disciplines to the Amazon environment. This book is a timely reminder of the crucial importance of our understanding of rainforest components and their interrelationships, appearing as it does at a period when there is an intense interest in this extremely endangered ecosystem.
Book News Annotation:
The Ilha de Maraca is a riverine island in the Rio Uraricoera, one of the principle tributaries of the Rio Branco. It is also an important example of the fringe forest- savannah environments of the northern rim of the Amazon basin. These 33 papers are the result of an intensive 1987-88 ecological survey that examined aspects of its biodiversity. Contributions discuss the geology, soils, vegetation, primates, bats, birds, reptiles, frogs, insects, earthworms, and rotifera of the island and how they all interact with their environment. A number of appendices list a number of the island's flora and fauna observed by the project but not discussed in the articles
