In Tropical Forest Ecology, Egbert G. Leigh, Jr., one of the world's foremost tropical ecologists, introduces readers to the tropical forest and describes the intricate web of interdependence among the great diversity of tropical plants and animals. Focusing on the tropical forest of Barro Colorado Island, Panama, Leigh shows what Barro Colorado can tell us about other tropical forests--and what tropical forests can tell us about Barro Colorado. This book considers three essential questions for understanding the ecological organization of tropical forests. How do they stay green with their abundance of herbivores? Why do they have such a diversity of plants and animals? And what role does mutualism play in the ecology of tropical forests? Beautifully written and abundantly illustrated, Tropical Forest Ecology will certainly appeal to a wide variety of scientists in the fields of evolution, tropical biology, botany, zoology, and natural history.

Recent decades have seen unprecedented growth in the scale and intensity of industrial forestry. Directly and indirectly, it has degraded the wildlife and ecological integrity of these tropical forests, prompting a need to evaluate the impact of current forest management practices and reconsider how best to preserve the integrity of the biosphere. Synthesizing the body of knowledge of leading scientists and professionals in tropical forest ecology and management, this book's thirty chapters examine in detail the interplay between timber harvesting and wildlife, from hunted and protected habitats to invertebrates and large mammal species. Collectively, the contributors suggest that better management is pivotal to the maintenance of the tropics' valuable biodiversity, arguing that we must realize that tropical forests harbor the majority (perhaps 70 to 80 percent) of the world's animal species. Further, they suggest modifications to existing practices that can ensure a better future for our valuable resources.

Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems

Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.

In evolutionary time scales natural disturbances have affected the vegetation on Earth. During the Quaternary the forest biomes of the tropics were subjected to manifold disturbances. Climate changes and climate oscillations were associated with changing precipitation and drought regimes, flooding, siltation, landslides, etc. The prehistorical forest was also influenced by the effects of large wildlife populations. Large-scale catastrophies in the forest biomes were mainly caused by abiotic environmental alterations, the small-scale disturbances were and still are related to both biotic and abiotic processes. Both the large-and the small-scale disturbances have played a significant role in shaping distribution, dynamics, structure and composition of the paleoforest. After the expansion of hominids and early humans, and later, by modern humans, the anthropogenic influences on the tropical forest began to overlap natural disturbances. Today's anthropogenic impacts on the tropical forests differ qualitatively and quanitatively from the natural disturbances. The speed of tropical deforestation and savannization is dramatically increasing. The physical and chemical impacts of forest conversion and biomass burning add to other anthropogenic influences on the atmosphere and climate. The expected anthropogenic climate change will also have considerable impacts on the tropical flora and fauna. The book on "Tropical Forests in Transition" synthesizes information on changing environmental conditions and human impacts on the tropical forest by looking back to the paleoecology, analyzing the impact of modern human populations and modeling the future of the tropical forest in a changing environment. The aim of the book is to strengthen multidisciplinary thinking in disturbance ecology.

The loss of biodiversity is a major environmental problem in nearly every terrestrial ecosystem on Earth. This loss is accelerating driven by climate change, as well as by other causes including agricultural exploitation, fragmentation and degradation triggered by land use changes. The crucial issue under debate is the impact on the welfare of current and future population, and the role of humans in the exploitation of natural resources. This is of particular importance in Central America, which it is amongst the richest and most threatened biodiversity regions on the Earth, and where the loss of ecosystems strongly affects its socio-economic vulnerability. This book addresses the impacts of climate and land-use change on tropical forest ecosystems in this important region, and assesses the expected economic costs if no policy action is taken, under different future scenarios and for different geographical scales. This innovative collection utilises both theoretical approaches and empirical results to provide a conceptual framework for an integrated analysis of climate and land-use change impacts on forest ecosystems and related economic effects, offering insight into the complex relationship between ecosystems and benefits to humans. This important contribution to forest ecosystems and climate change provides invaluable reading for students and scholars in the fields of environmental and ecological economics, environmental science and forestry, natural resource management, agriculture and climate change.
