This book was released on 2007 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small mammals are among the many taxa in the diverse southern Californian coastal sage scrub and chaparral ecosystems that are threatened by the exotic plant invasions, habitat destruction and fragmentation that have accompanied continued urbanization. Many small mammals not only rely on coastal sage scrub vegetation for shelter but also eat shrub seeds, and therefore depend upon their habitat while also having the ability to shape it. The studies presented here examine the effects of an El Niño-associated heavy rainfall event and invasion by exotic grasses on the small mammal community as well as the role of small mammals in mediating competition between native and exotic plants via selective seed predation. A 4 yr study that included the 1997-1998 El Niño (ENSO) rainfall event investigated changes in density and spatial distribution for 11 rodent species. In the period during and immediately after ENSO, 7 species increased in density and showed range expansions into previously unoccupied areas. The endangered kangaroo rat Dipodomys stephensi declined in abundance and spatial distribution during ENSO. A principle components analysis qualitatively showed changes in small mammal community composition that resulted from differences in relative abundance due to differing magnitudes of species' responses to high precipitation. Most species returned to pre-ENSO population densities and range sizes within 2 yr after El Niño. In addition to the transitory responses to the additional resources available after periods of high precipitation, small mammals also responded to longer-term, perhaps permanent, habitat changes resulting from disturbance-facilitated exotic grass invasions. At higher levels of invasion, abundance of shrub-associated small mammals declined while grass-associated species increased, and overall density of all small mammal species declined. Although no species exhibited a threshold response to invasion, invaded areas supported a depauperate mammal community largely composed of generalist species. Finally, a seed predation study found that rodents preferentially consumed seeds of exotic grasses and forbs over those of native shrubs and grasses. Total mass of seed removed and rates of seed tray visitation varied by season and small mammal density, but a preference for exotic seeds showed that small mammals might slow rates of exotic plant invasion

Download or read book Ecosystems of California written by Harold Mooney and published by Univ of California Press. This book was released on 2016-01-19 with total page 1008 pages. Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.

Download or read book Kumeyaay Ethnobotany written by Michael Wilken-Robertson and published by Sunbelt Publications. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For thousands of years, the Kumeyaay people of northern Baja California and southern California made their homes in the diverse landscapes of the region, interacting with native plants and continuously refining their botanical knowledge. Today, many Kumeyaay Indians in the far-flung ranches of Baja California carry on the traditional knowledge and skills for transforming native plants into food, medicine, arts, tools, regalia, construction materials, and ceremonial items. Kumeyaay Ethnobotany explores the remarkable interdependence between native peoples and native plants of the Californias through in-depth descriptions of 47 native plants and their uses, lively narratives, and hundreds of vivid photographs. It connects the archaeological and historical record with living cultures and native plant specialists who share their ever-relevant wisdom for future generations. Book jacket.
Book Synopsis Climate Intervention by : National Research Council
Download or read book Climate Intervention written by National Research Council and published by National Academies Press. This book was released on 2015-06-23 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing problem of changing environmental conditions caused by climate destabilization is well recognized as one of the defining issues of our time. The root problem is greenhouse gas emissions, and the fundamental solution is curbing those emissions. Climate geoengineering has often been considered to be a "last-ditch" response to climate change, to be used only if climate change damage should produce extreme hardship. Although the likelihood of eventually needing to resort to these efforts grows with every year of inaction on emissions control, there is a lack of information on these ways of potentially intervening in the climate system. As one of a two-book report, this volume of Climate Intervention discusses albedo modification - changing the fraction of incoming solar radiation that reaches the surface. This approach would deliberately modify the energy budget of Earth to produce a cooling designed to compensate for some of the effects of warming associated with greenhouse gas increases. The prospect of large-scale albedo modification raises political and governance issues at national and global levels, as well as ethical concerns. Climate Intervention: Reflecting Sunlight to Cool Earth discusses some of the social, political, and legal issues surrounding these proposed techniques. It is far easier to modify Earth's albedo than to determine whether it should be done or what the consequences might be of such an action. One serious concern is that such an action could be unilaterally undertaken by a small nation or smaller entity for its own benefit without international sanction and regardless of international consequences. Transparency in discussing this subject is critical. In the spirit of that transparency, Climate Intervention: Reflecting Sunlight to Cool Earth was based on peer-reviewed literature and the judgments of the authoring committee; no new research was done as part of this study and all data and information used are from entirely open sources. By helping to bring light to this topic area, this book will help leaders to be far more knowledgeable about the consequences of albedo modification approaches before they face a decision whether or not to use them.
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 OUP Oxford. This book was released on 2010-01-08 with total page 368 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.

Download or read book Ecology written by Michael Begon and published by John Wiley & Sons. This book was released on 2020-11-17 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen chapters. Nonetheless, the authors remain wedded to the belief that environmental action can only ever be as sound as the ecological principles on which it is based. Hence, while trying harder than ever to help improve preparedness for addressing the environmental problems of the years ahead, the book remains, in its essence, an exposition of the science of ecology. This new edition incorporates the results from more than a thousand recent studies into a fully up-to-date text. Written for students of ecology, researchers and practitioners, the fifth edition of Ecology: From Individuals to Ecosystems is anessential reference to all aspects of ecology and addresses environmental problems of the future.
Book Synopsis Ecology of Fragmented Landscapes by : Sharon K. Collinge
Download or read book Ecology of Fragmented Landscapes written by Sharon K. Collinge and published by JHU Press. This book was released on 2009-06 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Researchers have been studying the ecological effects of dismantling nature for decades. In this book, Collinge evaluates this body of research, expertly synthesizing all that is known about the ecology of fragmented landscapes. Expanding on the traditional coverage of this topic, Collinge also discusses disease ecology, restoration, conservation, and planning. Not since Richard T. T. Forman's classic Land Mosaics has there been a more comprehensive examination of landscape fragmentation. Ecology of Fragmented Landscapes is critical reading for ecologists, conservation biologists, and students alike.

Book excerpt: "Biodiversity." As argument over environmental and conservation policy grows more heated in California and throughout the nation, the term has become a buzzword. But what does biodiversity really mean? What really threatens it? Why should we care? In Our Own Hands offers a readable, scientifically sound view of California's biological diversity and what must be done to preserve it. The book will be an invaluable resource for environmental and natural resource specialists, educators, and general readers. Local and global forces threaten California's wetlands, dunes, oak woodlands, and riparian forest habitats--all declining habitats in a rapidly urbanizing, culturally heterogeneous, and politically turbulent state. Always a bellwether, California will be a model for the rest of the United States in its scientific and political solutions to conservation problems. This book proposes the first steps toward a unified national conservation policy for the twenty-first century. "Biodiversity."

Book Synopsis Fire and Climatic Change in Temperate Ecosystems of the Western Americas by : Thomas T. Veblen
Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.
