Book Synopsis Geographic Patterns of At-risk Species by : Curtis H. Flather
Download or read book Geographic Patterns of At-risk Species written by Curtis H. Flather and published by . This book was released on 2008 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical document supports the Forest Service's requirement to assess the status of renewable natural resources as mandated by the Forest and Rangeland Renewable Resources Planning Act of 1974. It updates past reports on the trends and geographic patterns of species formally listed as threatened or endangered under the Endangered Species Act of 1973. We compare the geographic occupancy of threatened and endangered species at the county-level against the geographic occupancy of a broader set of species thought to be at risk of extinction. This is done to determine if new areas where species rarity may be concentrated emerge. Here we document whether past trends and geographic occupancy patterns have changed over time, thereby providing resource planners and conservation practioners with updated information on where they should focus biodiversity conservation efforts.

Book Synopsis California Amphibian and Reptile Species of Special Concern by : Robert C. Thomson
Download or read book California Amphibian and Reptile Species of Special Concern written by Robert C. Thomson and published by Univ of California Press. This book was released on 2016-06-21 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.

Download or read book Appalachia's Coal-Mined Landscapes written by Carl E. Zipper and published by Springer Nature. This book was released on 2020-11-25 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collects and summarizes current scientific knowledge concerning coal-mined landscapes of the Appalachian region in eastern United States. Containing contributions from authors across disciplines, the book addresses topics relevant to the region’s coal-mining history and its future; its human communities; and the soils, waters, plants, wildlife, and human-use potentials of Appalachia’s coal-mined landscapes. The book provides a comprehensive overview of coal mining’s legacy in Appalachia, USA. It book describes the resources of the Appalachian coalfield, its lands and waters, and its human communities – as they have been left in the aftermath of intensive mining, drawing upon peer-reviewed science and other regional data to provide clear and objective descriptions. By understanding the Appalachian experience, officials and planners in other resource extraction- affected world regions can gain knowledge and perspectives that will aid their own efforts to plan and manage for environmental quality and for human welfare. Appalachia's Coal-Mined Landscapes: Resources and Communities in a New Energy Era will be of use to natural resource managers and scientists within Appalachia and in other world regions experiencing widespread mining, researchers with interest in the region’s disturbance legacy, and economic and community planners concerned with Appalachia’s future.
Book Synopsis Ecological Niches and Geographic Distributions (MPB-49) by : A. Townsend Peterson
Download or read book Ecological Niches and Geographic Distributions (MPB-49) written by A. Townsend Peterson and published by Princeton University Press. This book was released on 2011-10-31 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a first synthetic view of an emerging area of ecology and biogeography, linking individual- and population-level processes to geographic distributions and biodiversity patterns. Problems in evolutionary ecology, macroecology, and biogeography are illuminated by this integrative view. The book focuses on correlative approaches known as ecological niche modeling, species distribution modeling, or habitat suitability modeling, which use associations between known occurrences of species and environmental variables to identify environmental conditions under which populations can be maintained. The spatial distribution of environments suitable for the species can then be estimated: a potential distribution for the species. This approach has broad applicability to ecology, evolution, biogeography, and conservation biology, as well as to understanding the geographic potential of invasive species and infectious diseases, and the biological implications of climate change. The authors lay out conceptual foundations and general principles for understanding and interpreting species distributions with respect to geography and environment. Focus is on development of niche models. While serving as a guide for students and researchers, the book also provides a theoretical framework to support future progress in the field.
Book Synopsis Biogeography: A Very Short Introduction by : Mark V. Lomolino
Download or read book Biogeography: A Very Short Introduction written by Mark V. Lomolino and published by Oxford University Press. This book was released on 2020-07-23 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogeography is the study of geographic variation in all characteristics of life - ranging from genetic, morphological and behavioural variation among regional populations of a species, to geographic trends in diversity of entire communities across our planet's sufrace. From the ancient hunters and gatherers to the earliest naturalists, Charles Darwin, Alfred Russel Wallace, and scientists today, the search for patterns in life has provided insights that proved invaluable for understanding the natural world. And many, if not most, of the compelling kaleidoscope of patterns in biological diversity make little sense unless placed in an explicit geographic context. The Very Short Introduction explains the historical development of the field of biogeography, its fundamental tenets, principles and tools, and the invaluable insights it provides for understanding the diversity of life in the natural world. As Mark Lomolino shows, key questions such as where species occur, how they vary from place to place, where their ancestors occurred, and how they spread across the globe, are essential for us to develop effective strategies for conserving the great menagerie of life across our planet. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Synopsis Conservation Biology for All by : Navjot S. Sodhi
Download or read book Conservation Biology for All written by Navjot S. Sodhi and published by Oxford University Press. This book was released on 2010 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.

Book Synopsis The Structure and Dynamics of Geographic Ranges by : Kevin J. Gaston
Download or read book The Structure and Dynamics of Geographic Ranges written by Kevin J. Gaston and published by OUP Oxford. This book was released on 2003-05-01 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: No species occurs everywhere. Indeed, the majority are absent from most places, and where they do occur they are usually quite rare. Gaston discusses the structure of these distributions - the structure of the geographic ranges of species. Gaston is particularly concerned with the factors that determine the limits to a species' geographic range, how the sizes of those ranges vary, and patterns in that variation. Also considered are the distribution of individuals amongst those sites where a species does occur and what determines that distribution, and some of the practical implications of all these. Both in a pure and applied context, ecologists need a broader perspective on their subject matter than has historically prevailed. This book provides one such perspective. A must have book for any researchers and graduate students studying macroecology, biogeography and conservation biology.
Book Synopsis The Geographical Sciences During 1986—2015 by : Shuying Leng
Download or read book The Geographical Sciences During 1986—2015 written by Shuying Leng and published by Springer. This book was released on 2016-07-28 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: In four chapters and an introduction, this book systematically helps readers understand the development of the Geographical Sciences both in China and in the world during the past 30 years. Through data analysis of methodologies including CiteSpace, TDA, qualitative analysis, questionnaires, data mining and mathematical statistics, the book explains the evolution of research topics and their driving factors in the Geographical Sciences and its four branches, namely Physical Geography, Human Geography, Geographical Information Science and Environmental Geography. It also identifies the role of the Geographical Sciences in the analysis of strategic issues such as global change and terrestrial ecosystems, terrestrial water cycle and water resources, land change, global cryosphere evolution and land surface processes on the Tibetan Plateau, economic globalization and local responses, regional sustainable development, remote sensing modelling and parameter inversion, spatial analysis and simulation, and tempo-spatial processes and modelling of environmental pollutants. It then discusses research development and inadequacy of Chinese Geographical Sciences in the above-mentioned topics, as well as in the fields including Geomorphology and Quaternary environmental change, Ecohydrology, ecosystem services, the urbanization process and mechanism, medical and health geography, international rivers and transboundary environment and resources, detection and attribution of changes in land surface sensitive components, and uncertainty of spatial information and spatial analysis. It shows that the NSFC has driven the development in all these topics and fields. In addition, the book summarises trends of the Geographical Sciences in China and the research level in major countries of the world through an overview of geographical education in colleges and universities, the analysis of publications, citations and author networks of SCI/SSCI and CSCD indexed articles, and the description of Sino-USA, Sino-UK and Sino-German cooperation. This book serves as an important reference to anyone interested in geographical sciences and related fields.
