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.

Download or read book Physiological ecology of plants of the wet tropics written by Ernesto Medina and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the results of a Symposium on the physiological ecology of plants of the lowland wet tropics held in Mexico in June 1983 organized by the Instituto de Biologla of the National University of M"exico (U. N . A. M. ), and sponsored by UNAM, CONACYT, NSF and UNESCO (CIET). A workshop portion of the Symposium was held at the tropical research station at Los Tuxtlas, Veracruz. This Symposium originated in response to the increasing interest in the physiological ecology of tropical plants, because of the potential. of this field to provide a basic understanding of functioning of tropical plant communities. The study of physiological ecology of tropical plants has been delayed in some cases by the lack of conceptual framework, but also by the absence of appropriate instrumentation and techniques with which to conduct precise measurements under high temperature, high humidity field conditions. Hypotheses and concepts of the physiological ecology of tropical plants have been based mainly on observational data and the analysis of growth forms and leaf anatomf. The early work of A. F. W. Schimper and o. Stocker in Asia, and the extensive surveys made by H. Walter on the osmotic potentials of plants in the tropics and subtropics, constituted, until relatively recently, the only available information on the water and carbon relations of tropical plants.
Download or read book Microclimate Vegetation Fauna written by Ph. Stoutjesdijk and published by BRILL. This book was released on 2015-11-24 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Microclimate, Vegetation & Fauna the ecologist meets the meteorologist: it is about the biological aspects of microclimate and its variation in horizontal and vertical directions. The great diversity found in the various habitats is stressed, also as far as the microclimate is concerned.The stronghold of this book on microclimatology or the ‘minor weather’ in the immediate surroundings of plants and animals is its capacity to unravel the causal relationships between climate, topography, soils, vegetation and fauna. The manifold interactions in between are explained in detail and it is concluded that the connections are so intimate that each species has its own microclimate. This book is unique and interesting for a wide audience. It specifically targets natural scientists and students in biology with an interest in climatology and climatologists with an interest in biology.
Download or read book Frugivores and seed dispersal written by Alejandro Estrada and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide variety of plants, ranging in size from forest floor herbs to giant canopy trees, rely on animals to disperse their seeds. Typical values of the proportion of tropical vascular plants that produce fleshy fruits and have animal-dispersed seeds range from 50-90%, depending on habitat. In this section, the authors discuss this mutualism from the plant's perspective. Herrera begins by challenging the notion that plant traits traditionally interpreted as being the product of fruit-frugivore coevolution really are the outcome of a response-counter-response kind of evolutionary process. He uses examples of congeneric plants living in very different biotic and abiotic environments and whose fossilizable characteristics have not changed over long periods of time to argue that there exists little or no basis for assuming that gradualistic change and environmental tracking characterizes the interactions between plants and their vertebrate seed dispersers. A common theme that runs through the papers by Herrera, Denslow et at. , and Stiles and White is the importance of the 'fruiting environment' (i. e. the spatial relationships of conspecific and non-conspecific fruiting plants) on rates of fruit removal and patterns of seed rain. Herrera and Denslow et at. point out that this environment is largely outside the control of individual plant species and, as a result, closely coevolved interactions between vertebrates and plants are unlikely to evolve.
Download or read book Ecosystems of Disturbed Ground written by L.R. Walker and published by Elsevier. This book was released on 1999-12-17 with total page 881 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Any scientific discipline needs a theoretical framework to guide its development and to sharpen the questions its researchers pursue. In biology, evolution is the grand theoretical framework, and an his torical perspective is necessary to understand present-day biological conditions. In its formative years, the modern study of the fruit-frugivore mutualism was guided by the 'specialist-generalist' paradigm developed by D. Snow, D. McKey, and H. Howe. Howe reviews the current status of this evolution ary paradigm and points out that it has been dismissed by many workers before being adequately tested. This is because ecologists working with the tropical plants and frugivorous birds for which the paradigm was originally developed rarely measure the seed dispersal effectiveness of different disperser species. He indicates that this paradigm still has heuristic value and suggests that several additional ecological paradigms, including the concept ofkeystone species ofplants and frugivores and the role that frugivores play in density-dependent mortality in tropical trees, are worth studying. The concept of seed dispersal quality has been central to discussions of fruit-frugivore coevolution. Schupp thoroughly reviews data bearing on this concept, constructs a hierarchical framework for viewing disperser effectiveness, and points out that disperser effectiveness depends on both the quantity and quality of seed dispersal. Effectiveness, in turn, affects both evolutionary and ecological relationships between dispersers and their food plants.
