This book was released on 1987 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report develops the theoretical foundation for analytical description and quantification of habitat structure. The analytical description of environmental gradients is shown to be an eigenanalysis problem, mathematically equivalent to the largest eigenvector (or first principal component) of a principal components analysis. The analytical representation of an environmental gradient, itself a single variable, is empirically demonstrated to have similar ecological information as the combination of all the original 58 habitat variables describing five Mojave Desert study sites. Two vastly different data bases were analyzed to explore the effects of sample sizes and variable selection on the ordination of study sites in both principal components and canonical variate space. Merits and shortcomings of principal components analysis, canonical analysis of discriminance, and cluster analysis for the ordination and classification of samples are reviewed in detail. Canonical analysis of discriminance is a very effective mechanism for classifying samples into a priori established groups, or for identifying variables that contribute significantly to group discrimination.

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.

Download or read book The American West at Risk written by Howard G. Wilshire and published by Oxford University Press. This book was released on 2008-06-05 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American West at Risk summarizes the dominant human-generated environmental challenges in the 11 contiguous arid western United States - America's legendary, even mythical, frontier. When discovered by European explorers and later settlers, the west boasted rich soils, bountiful fisheries, immense, dense forests, sparkling streams, untapped ore deposits, and oil bonanzas. It now faces depletion of many of these resources, and potentially serious threats to its few "renewable" resources. The importance of this story is that preserving lands has a central role for protecting air and water quality, and water supplies--and all support a healthy living environment. The idea that all life on earth is connected in a great chain of being, and that all life is connected to the physical earth in many obvious and subtle ways, is not some new-age fad, it is scientifically demonstrable. An understanding of earth processes, and the significance of their biological connections, is critical in shaping societal values so that national land use policies will conserve the earth and avoid the worst impacts of natural processes. These connections inevitably lead science into the murkier realms of political controversy and bureaucratic stasis. Most of the chapters in The American West at Risk focus on a human land use or activity that depletes resources and degrades environmental integrity of this resource-rich, but tender and slow-to-heal, western U.S. The activities include forest clearing for many purposes; farming and grazing; mining for aggregate, metals, and other materials; energy extraction and use; military training and weapons manufacturing and testing; road and utility transmission corridors; recreation; urbanization; and disposing of the wastes generated by everything that we do. We focus on how our land-degrading activities are connected to natural earth processes, which act to accelerate and spread the damages we inflict on the land.

Book excerpt: In July 1993 a remarkable group of ecologists, conservationists, land managers, government officials, & policy-makers representing 25 nations gathered at Purchase, New York, to attend a conference devoted to the conservation, restoration, & management of tortoises & turtles. Offering just a glimpse of the troubled conservation status of the world's 270-plus species of tortoises & turtles, the 77 papers & summary reports (as well as abstracts of presented posters) included in the proceedings represent the combined efforts of more than 130 authors & 35 reviewers. The material presented in this 494-page volume, organized by the major subject areas of the 1993 conference, roughly corresponds to the daily sessions of the meeting: Direct & Indirect Threats to Habitat; Direct Loss of Population - Disease, Predation, & Human Exploitation; Breeding, Repatriation, & Relocation; Applications of Demography, Ecology, & Genetics to Conservation; Status Reports; Species Recovery & Management Strategies; Reserves & Programs; & Integrated Management Strategies & Public Policy. Abstracts of the presented posters appear in a separate section. "Together the papers in this volume lay the groundwork for what one might call a theoretical basis for the science of chelonian conservation, an exercise that has never been attempted before."--Peter C. H. Pritchard, author ENCYCLOPEDIA OF TURTLES. Direct inquiries to: [email protected].

Download or read book Landscape Simulation Modeling written by Robert Costanza and published by Springer Science & Business Media. This book was released on 2006-06-02 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world consists of many complex systems, ranging from our own bodies to ecosystems to economic systems. Despite their diversity, complex systems have many structural and functional features in common that can be effectively si- lated using powerful, user-friendly software. As a result, virtually anyone can - plore the nature of complex systems and their dynamical behavior under a range of assumptions and conditions. This ability to model dynamic systems is already having a powerful influence on teaching and studying complexity. The books in this series will promote this revolution in “systems thinking” by integrating computational skills of numeracy and techniques of dynamic mod- ing into a variety of disciplines. The unifying theme across the series will be the power and simplicity of the model-building process, and all books are designed to engage the reader in developing their own models for exploration of the dyn- ics of systems that are of interest to them. Modeling Dynamic Systems does not endorse any particular modeling paradigm or software. Rather, the volumes in the series will emphasize simplicity of lea- ing, expressive power, and the speed of execution as priorities that will facilitate deeper system understanding.

Download or read book Warfare Ecology written by Gary E. Machlis and published by Springer. This book was released on 2011-06-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is specific and ambitious: to outline the distinctive elements, scope, and usefulness of a new and emerging field of applied ecology named warfare ecology. Based on a NATO Advanced Research Workshop held on the island of Vieques, Puerto Rico, the book provides both a theoretical overview of this new field and case studies that range from mercury contamination during World War I in Slovenia to the ecosystem impacts of the Palestinian occupation, and from the bombing of coral reefs of Vieques to biodiversity loss due to violent conflicts in Africa. Warfare Ecology also includes reprints of several classical papers that set the stage for the new synthesis described by the authors. Written for environmental scientists, military and humanitarian relief professionals, conservation managers, and graduate students in a wide range of fields, Warfare Ecology is a major step forward in understanding the relationship between war and ecological systems.
