Book Description
Underdeveloping the Amazon shows how different extractive economies have periodically enriched various dominant classes but progressively impoverished the entire region by disrupting both the Amazon Basin's ecology and human communities. Contending that traditional models of development based almost exclusively on the European and American experience of industrial production cannot apply to a regional economy founded on extraction, Stephen G. Bunker proposes a new model based on the use and depletion of energy values in natural resources as the key to understanding the disruptive forces at work in the Basin.

Book Description
Central Amazonian floodplain forests are an unique and endangered ecosystem. The forests grow in areas that are annually flooded by large rivers during mean periods of up to 8 months and at depths of up to 10 m. Despite this severe stress, these forests consist of over 1,000 species and are by far the most species-rich floodplain forests worldwide. The trees show a broad range of morphological, anatomical, physiological, and phenological adaptations that enable them not only to survive the adverse environmental conditions, but also to produce large amounts of biomass when the nutrient levels in water and soils are sufficiently high. This is the case in the floodplains of white-water rivers, which are used for fisheries, agriculture, and cattle-ranching but which also have a high potential for the production of timber and non-timber products, when adequately managed. Latest research on ecophysiology gives insight how tree species adapt to the oscillating flood-pulse focusing on their photosynthesis, respiration, sap flow, biochemistry, phenology, wood and leave anatomy, root morphology and functioning, fruit chemistry, seed germination, seedling establishment, nitrogen fixation and genetic variability. Based on tree ages, lifetime growth rates and net primary production, new concepts are developed to improve the sustainability of traditional forest managements in the background of an integrated natural resource management. This is the first integrative book on the functioning and ecologically oriented use of floodplain forests in the tropics and sub-tropics.It provides fundamental knowledge for scientist, students, foresters and other professionals on their distribution, evolution and phytogeography. “This book is an excellent testimony to the interdisciplinary collaboration of a group of very dedicated scientists to unravel the functioning of the Amazonian Floodplain forests. They have brought together a highly valuable contribution on the distribution, ecology, primary production, ecophysiology, typology, biodiversity, and human use of these forests offering recommendations for sustainable management and future projects in science and development of these unique wetland ecosystems. It lays a solid scientific foundation for wetland ecologists, foresters, environmentalists, wetland managers, and all those interested in sustainable management in the tropics and subtropics.” Brij Gopal, Executive Vice President International Society for Limnology (SIL).

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 groundbreaking study engages with the theoretical aspects of realism - a long neglected area in film studies.. Contributes to an understanding of how popular films use realist forms to address contentious social and political issues such as social exclusion, war and violence.. Focusing on key moments in film history the authors examine the uses of realism in national cinemas as a context for their in-depth analysis of contemporary popular films.. A series of case studies examines the hybrid styles of realism used in recent filmmaking practice and the politics of these forms in relation to topics such as urban youth and domestic violence (Boyz N the Hood, La Haine, Once Were Warriors, Ladybird, Ladybird, Nil By Mouth), government conspiracies and war (Cry Freedom, JFK, Schindler's List), and serial killers (Henry, Portrait of a Serial Killer, Man Bites Dog, Natural Born Killers).. Will give rise to new directions in the theorisation of both popular film and realism in the cinema.

Book Description
It is increasingly recognized that the economic value of forests is not merely the production of timber. Forests provide other key ecosystem services, such as being sinks for greenhouse gases, hotspots of biodiversity, tourism and recreation. They are also vitally important in preventing soil erosion and controlling water supplies, as well as providing non-timber forest products and supporting the livelihoods of many local people. This handbook provides a detailed, comprehensive and broad coverage of forest economics, including traditional forest economics of timber production, economics of environmental role of forests, and recent developments in forest economics. The chapters are grouped into six parts: fundamental topics in forest resource economics; economics of forest ecosystems; economics of forests, climate change, and bioenergy; economics of risk, uncertainty, and natural disturbances; economics of forest property rights and certification; and emerging issues and developments. Written by leading environmental, forest, and natural resource economists, the book represents a definitive reference volume for students of economics, environment, forestry and natural resource economics and management.

Book Description
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

Book Description
As the human population inexorably grows, its cumulative impact on the Earth's resources is hard to ignore. The ability of the Earth to support more humans is dependent on the ability of humans to manage natural resources wisely. Because disturbance alters resource levels, effective management requires understanding of the ecology of disturbance. This book is the first to take a global approach to the description of both natural and anthropogenic disturbance regimes that physically impact the ground. Natural disturbances such as erosion, volcanoes, wind, herbivory, flooding and drought plus anthropogenic disturbances such as foresty, grazing, mining, urbanization and military actions are considered. Both disturbance impacts and the biotic recovery are addressed as well as the interactions of different types of disturbance. Other chapters cover processes that are important to the understanding of disturbance of all types including soil processes, nutrient cycles, primary productivity, succession, animal behaviour and competition. Humans react to disturbances by avoiding, exacerbating, or restoring them or by passing environmental legislation. All of these issues are covered in this book.Managers need better predictive models and robust data-collections that help determine both site-specfic and generalized responses to disturbance. Multiple disturbances have a complex effect on both physical and biotic processes as they interact. This book provides a wealth of detail about the process of disturbance and recovery as well as a synthesis of the current state of knowledge about disturbance theory, with extensive documentation.
