Book Synopsis Tropical Forest Ecology by : Egbert Giles Leigh Jr.
Download or read book Tropical Forest Ecology written by Egbert Giles Leigh Jr. and published by Oxford University Press. This book was released on 1999-03-04 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Tropical Forests: Management and Ecology by : Ariel E. Lugo
Download or read book Tropical Forests: Management and Ecology written by Ariel E. Lugo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forestry professors used to remind students that, whereas physicians bury their mistakes, foresters die before theirs are noticed. But good institutions live longer than the scientists who contribute to building them, and the half-century of work of the USDA Forest Service's Institute of Tropical Forestry (ITF) is in plain view: an unprecedented corpus of accomplishments that would instill pride in any organization. There is scarcely anyone interested in current issues of tropical forestry who would not benefit from a refresher course in ITF's findings: its early collaboration with farmers to establish plantations, its successes in what we now call social forestry, its continuous improvement of nursery practices, its screening trials of native species, its development of wood-processing technologies appropriate for developing countries, its thorough analysis of tropical forest function, and its holistic approach toward conservation of endangered species. Fortunately, ITF has a long history of information exchange through teaching; like many others, I got my own start in tropical forest ecology fromjust such a course in Puerto Rico. And long before politicians recognized the global importance of tropical forestry, the ITF staff served actively as ambassadors of the discipline, visiting tropical coun tries everywhere to learn and, when invited to do so, to help solve local problems. It is a general principle of biogeography that species' turnover rates on islands are higher than those on continents. Inevitably, the same is true of scientists assigned to work on islands.
Book Synopsis Tropical Forest Community Ecology by : Walter Carson
Download or read book Tropical Forest Community Ecology written by Walter Carson and published by John Wiley & Sons. This book was released on 2011-08-31 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Dryland Ecohydrology by : Paolo D'Odorico
Download or read book Dryland Ecohydrology written by Paolo D'Odorico and published by Springer Science & Business Media. This book was released on 2006-01-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecohydrology emerges as a new field of research aiming at furthering our understanding of the earth system through the study of the interactions between the water cycle and vegetation. By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this volume provides a synthesis of material on arid and semiarid landscapes, which is currently spread in a number of books and journal articles. The focus on water-limited ecosystems is motivated by their high sensitivity to daily, seasonal, and decadal perturbations in water availability, and by the ecologic, climatic, and economic significance of most of the drylands around the world. Conceived as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. The chapters collected in this book have been contributed by authors with different expertise, who work in several arid areas around the World. They describe the various interactions among the biological and physical dynamics in dryland ecosystems, starting from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns.
Book Synopsis New Perspectives on Nitrogen Cycling in the Temperate and Tropical Americas by : Alan R. Townsend
Download or read book New Perspectives on Nitrogen Cycling in the Temperate and Tropical Americas written by Alan R. Townsend and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inputs of nitrogen to terrestrial and aquatic ecosystems have increased several-fold over the last one hundred and fifty years, with the steepest increases during the last four decades. The expansion of fertilizer manu facture and use, the increase in fossil fuel combustion, the intensification of animal husbandry, and widespread cultivation of N2 fixing crops have all contributed to the dramatic increase in N inputs. The increase has been most rapid in Northern Hemisphere (NH) temperate ecosystems, but presently subtropical and tropical regions of Asia are also experiencing an explosive increase in N inputs to terrestrial ecosystems (W. Chameides, pers. comm. ; Galloway et al. 1996). Projected increases in N deposition for these trop ical and subtropical regions, with a high natural background of N inputs, exceed increases projected for temperate and arctic regions (Cleveland et al. submitted; Galloway et al. 1994; Holland & Lamarque 1997a). Compared to biological N fixation, N deposition is becoming a proportionately greater source of N to terrestrial and aquatic ecosystems worldwide (Vitousek et al. 1997). 6 The nitrogen contained in the atmosphere as N , 3. 9 * 10 Tg (Tg = 2 12 10 g), is the largest reservoir of N in the Earth system (Warneck 1988). However, this paper focuses on the nitrogen emissions and deposition that have been transformed from N2 into reactive forms that are biologically avail able (e. g. Vitousek et al. 1997).
Book Synopsis Tropical Rain Forest: A Wider Perspective by : F.B. Goldsmith
Download or read book Tropical Rain Forest: A Wider Perspective written by F.B. Goldsmith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international perspective for this book is the unprecedented level of concern over deforestation, recognized by the meeting of world leaders at the 1992 Earth Summit, in Rio do Janeiro, and culminating in the appoint ment of the Intergovernmental Panel on Forests (IPF), under the auspices of the UN Commission on Sustainable Development. The wide range of issues covered by the authors in this volume reflects the breadth of the interna tional debate, from national policies and activist campaigning, through eco nomic and social objectives, to the sustainable management of forest and soil resources. Since the conservation campaigns of the 1980s, the focus of international concern has widened from tropical rain forests to all forest formations, in all regions, with increased recognition of global values and common responsibil ities. However, while forest cover in some temperate countries is increasing, irrational deforestation, at historically unprecedented levels of damage to biodiversity and to other environmental values, remains most acute in tropi cal countries, where the need to use the natural resources for sustainable development is greatest, and the capability weakest. While accepting the urgency of the situation, and the need for greater coherence of action at a global level, the 1997 report of the IPF to the UN Commission emphasized the powers and responsibilities of national governments, and the importance of National Forest Programmes, but with the fuller participation of local communities, and with enhanced access to international assistance.
Book Synopsis Potential Impacts of Climate Change on Tropical Forest Ecosystems by : Adam Markham
Download or read book Potential Impacts of Climate Change on Tropical Forest Ecosystems written by Adam Markham and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change represents one of the most alarming long-term threats to ecosystems the world over. This new collection of papers provides, for the first time, an overview of the potentially serious impact that climate change may have on tropical forests. The authors, a multi-disciplinary group of leading experts in climatology, forestry, ecology and conservation biology, present a state-of-knowledge snapshot of how tropical forests are likely to react to the changes being wrought on our planet's atmosphere and climate. Tropical forests represent extraordinary harbours for biological diversity, and yet as deforestation and degradation continue apace, they are under greater pressure from human impacts than ever before. Climate change adds yet another threat to these valuable ecosystems, and this volume demonstrates just how significant a problem this may really be. The authors identify certain types of forest, including tropical montane cloud forest that may be particularly vulnerable. They also show the strong likelihood of global warming aggravating problems in already fragmented forest areas.

Book Synopsis Human Activities and the Tropical Rainforest by : Bernard K. Maloney
Download or read book Human Activities and the Tropical Rainforest written by Bernard K. Maloney and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arising initially from a conference, the papers published here have been integrated into book form to provide information on human activities and the tropical rainforest in the past and present, and on the possible future of the rainforest, in a unique way. Other books have considered some, but not all, of these themes; however, none has stressed the continuity of change over time and its possible outcome for the people of the forest as well as for the forest itself. Because of the approach taken, this book should appeal across traditional disciplinary boundaries. Indeed a prime aim has been to suggest that rainforest, because of its complexity and the complexity of people-rainforest relationships throughout time, deserves study from a broad perspective. This book poses more questions than answers about the rainforest and it is hoped that it will encourage readers to think about the rainforest in a wider way than hitherto. This book is aimed at geographers (physical and human), social anthropologists, archaeologists, pedologists, foresters and tropical botanists and will be of value to graduates of various disciplines setting out to research the rainforest.
