Download Terrestrial Ecoregions of North America Book in PDF, ePub and Kindle
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 With a significant number of previously unpublished data sets and new analytic approaches, Terrestrial Ecoregions of North America is both a guidebook for describing the biological wealth of the continent and a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.

Download Ecoregions Book in PDF, ePub and Kindle
Global warming and human-driven impacts are changing the World’s ecological zones. This book applies the principles described in Bailey’s Ecosystem Geography: From Ecoregions to Sites, 2nd ed. (Springer 2009, 1st ed. 1996) to describe and characterize the major terrestrial and aquatic ecological zones of the Earth. Bailey’s system for classifying these zones has been adopted by major organizations such as the U.S. Forest Service and The Nature Conservancy and this book is a significant contribution to a long tradition of classifying and studying the world’s ecological regions or ecoregions. It includes two color maps that show the major ecoregions of the continents and oceans. Also included are: - 106 illustrations with 55 in full color - A new chapter on mountains is included. - There are new sections that address concerns about how eco regions are changing under the relentless influence of humans and climate change - Another new feature is the discussion of using eco regional patterns to transfer research results and select sites for detecting climate change effects on ecosystem distribution - Use of ecoregional patterns to design monitoring networks and sustainable landscapes - Fire regimes in different regional ecosystems and their management implications.

Download EcoRegions of Alaska Book in PDF, ePub and Kindle
Produced as a framework for organizing and interpreting environmental data for inventory, monitoring, and research efforts. The descriptions of the 20 ecoregions of Alaska contained in this guide were derived by synthesizing information on the geographic distribution of environmental factors such as climate, terrain, soils, and vegetation. The specific procedures and materials used to delineate the ecoregion boundaries are documented, and the environmental characteristics in each ecoregion are described. Accompanied by a full-color oversize map of the ecoregions, their boundaries, and transitional areas. 42 full-color photos.

Download Ecosystem Geography Book in PDF, ePub and Kindle
This book outlines a system that subdivides the Earth into a hierarchy of increasingly finer-scale ecosystems that can serve as a consistent framework for ecological analysis and management. The system consists of a three-part, nested hierarchy of ecosystem units and associated mapping criteria. This new edition has been updated throughout with new text, figures, diagrams, photographs, and tables.

Download The Ecoregions of Saskatchewan Book in PDF, ePub and Kindle
This book describes the ecoregions of Saskatchewan, following a hierarchical framework for terrestrial ecosystems in Canada. The introduction reviews ecological land classification and the various interrelated factors that are involved in the development of ecosystems: geology, water, climate, vegetation, soils, wildlife, and human impacts. The main section describes the province within the context of the four ecozones and 11 ecoregions that were identified in the framework. For each ecoregion, the book provides a description of the physical setting, such as geology & climate, as well as the biological features that have developed in response to this physical environment. The impact of human activities on the ecology of the area concludes each of these descriptions. Appendices include lists of animal & plant species found in Saskatchewan and a glossary.

Download Marine Ecoregions of North America Book in PDF, ePub and Kindle
Describes and maps the North American oceanic and coastal waters, classifying them into 24 marine ecoregions, according to oceanographic features and geographically distinct assemblages of species. Descriptive profiles of the ecoregions describe their key features, in terms of physical, oceanographic, and biological characteristics, as well as human impacts. The book is intended to provide a framework for collecting and organizing information on these regions, and to encourage a sense of joint responsibility and a collaborative strategic approach to dealing with the challenges of conserving the regions' shared oceans.

Download Ecological Regions of North America Book in PDF, ePub and Kindle
This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.
