Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

This book was released on 2013-01-01 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this well-illustrated book, Hildebrand expands upon his model for the development of the North American Cordillera detailed in Special paper 457. Starting with an overview of Cordilleran geology he goes on to provide an in depth look at how the Rubian ribbon continent was assembled. He integrates the complex geology of the Cordillera into an actualistic model involving arc magmatism, arc-continent collision, slab failure magmatism, and transcurrent motion in both Rubia and the western North American margin. While much of the focus is on the assembly of the Rubian ribbon continent, Hildebrand explores its interactions with North America during the Sevier and Laramide events and concludes that North America was the lower plate in both"--Provided by publisher.

Book Synopsis Beyond Naturalness by : David N. Cole
Download or read book Beyond Naturalness written by David N. Cole and published by Island Press. This book was released on 2012-06-22 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central concept guiding the management of parks and wilderness over the past century has been “naturalness”—to a large extent the explicit purpose in establishing these special areas was to keep them in their “natural” state. But what does that mean, particularly as the effects of stressors such as habitat fragmentation, altered disturbance regimes, pollution, invasive species, and climate change become both more pronounced and more pervasive? Beyond Naturalness brings together leading scientists and policymakers to explore the concept of naturalness, its varied meanings, and the extent to which it provides adequate guidance regarding where, when, and how managers should intervene in ecosystem processes to protect park and wilderness values. The main conclusion is the idea that naturalness will continue to provide an important touchstone for protected area conservation, but that more specific goals and objectives are needed to guide stewardship. The issues considered in Beyond Naturalness are central not just to conservation of parks, but to many areas of ecological thinking—including the fields of conservation biology and ecological restoration—and represent the cutting edge of discussions of both values and practice in the twenty-first century. This bookoffers excellent writing and focus, along with remarkable clarity of thought on some of the difficult questions being raised in light of new and changing stressors such as global environmental climate change.

Book Synopsis Terrestrial Ecoregions of North America by : Taylor H. Ricketts
Download or read book Terrestrial Ecoregions of North America written by Taylor H. Ricketts and published by Washington, D.C. : Island Press. This book was released on 1999 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lauded in the New York Times science section as "a sweeping analysis of the ecosystems of the United States and Canada," this volume represents an unparalleled source of information and data for scientists and conservationists working in North America. Using a rigorous ecoregion-based approach, rather than the more common state-by-state analysis, a team of scientists from World Wildlife Fund has produced a stunning and comprehensive assessment of the current status of biodiversity in North America north of Mexico. Terrestrial Ecoregions of North America begins with six chapters that present the rationale for the ecoregion approach, describe the biological distinctiveness of North American ecoregions, assess the level of threats facing each, present a conservation agenda for the next decade, and set forth recommendations for preserving and restoring biodiversity. In addition, nineteen essays by leading scientists address specific topics such as the effect of cattle on riparian areas, and the problem of invasive exotic plant species. Following the main text are substantial appendixes that describe each ecoregion in detail, including information on: unique features of the ecoregion that set it apart from the others its biological distinctiveness, threats to habitats and wildlife, and important sites for conservation activities that enhance biodiversity conservation in the ecoregion conservation partners working in the ecoregion, including addresses and other contact information the relationship of the ecoregion to other classification schemes literature cited for that ecoregion One of the most useful and unique features of the book is the series of thirty full-color maps that present essential information about the ecoregions and the biodiversity they contain in a compelling and easily understood graphical format. The ecoregion-based approach has been adopted by many conservation groups as the most effective way to ward off massive losses of biodiversity, and this volume provides a road map to that important new strategy. With a significant number of previously unpublished data sets and new analytic approaches, Terrestrial Ecoregions of North America is both a guidebook for describing the biological wealth of the continent and a handbook for restoring and conserving it. It will be an essential reference for anyone concerned with biodiversity conservation in North America.
