This book was released on 1991 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Establishment of species on floodplains, and consequent zonal distribution and succession, are associated with allogenic factors as soil moisture holding capacity, and to autogenic elements such asw dispersion, germination, and seedling growth rate and shade tolerance. This investigation focused on the identification of how some of these allogenic and autogenic factors may be related withy woody riparian species zonal distribution. The species studied were the pioneers Salix hindsiana Benth., S. laevigata Bebb. and Populus fremontii S. Wats, and the late successional species Aacer negundo L. ssp. californicum (T & G) Wesmael and Jugalns hindsii Jepson. Results provided evidence that earlier and shorter reproductive period allows pioneer species to have mature seed dispersed during the sdame season. Earlier seed maturation and dispersion allows colonization of new areas at the edge creek created by spring flooding. Lack of water at establishment is not a major problem because it occurs at the edge of the creek. In contrast, the longer reproductive period and the dispersal and the dispersal time during early winter for the late successional species provides the necessary chilling to overcome dormancy. Germination generally occrs late in the mild winter of California Central Valley, where soil at a greater distance from the creek is stillmoist from wintewr rain and creek flooding. The germination requirements regarding light, temperature, and soil moisture shows general trends among seed characteristics. Similarities shared by pioneer species were very short seed very short seed longevity and absense of dormancy. In contrast, late successional species exhibited longer seed viability and winter dormancy. Initial growth and seed size in two of the selected species, P. fremontii (pioneer) and A. negundo (late-successional) were related to light availability. The pioneer species P. fremontii showed Small wind disperesd seeds, and seedling with faste growth rate and shade intolerance. These are trpical necessary characteristics of especies which colonize open areas mostly available at the creweks at the period of seed dispersal and germination. Incontrast, A. negundo had relatively bigger seeds with less dispersal mobility and earlier establishment during the growth season and seedlings showed a steady growth rate and good shade tolerance. The charcteristics of a seed dormancy requirement, seed germination early in the growing season and shade tolerance are advantageous for late successional species growing on relatively drier sites in riparian ecosystems.

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.
Book Synopsis Riparian Areas by : National Research Council
Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Synopsis River Ecology and Management by : Robert Naiman
Download or read book River Ecology and Management written by Robert Naiman and published by Springer Science & Business Media. This book was released on 2001-02-16 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.

Book Synopsis From the Sierra to the Sea by : William S. Alevizon
Download or read book From the Sierra to the Sea written by William S. Alevizon and published by Bookbaby. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original report From the Sierra to the Sea: Ecological History of the San Francisco Bay-Delta Watershed was a product of a three-year effort to develop a landscape level overview of the natural ecological structure, function and organization of the watershed, and the way it had changed over the course of the 19th and 20th centuries. Technical review and contributions from government and water agencies helped produce a collaborative document that provided information on the historical ecological baseline in order to assist in what was envisioned at the time as the most ambitious restoration effort ever undertaken in the United States. We are proud of the fact that the original document is still used as an objective reference, and has provided a foundation and inspiration for similar but more intensively researched localized efforts by others in the Bay-Delta watershed. This 20th anniversary edition contains a new Afterword describing changes to the estuary and its watershed since the report was originally published in 1998.

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 New Strategies for America's Watersheds by : National Research Council
Download or read book New Strategies for America's Watersheds written by National Research Council and published by National Academies Press. This book was released on 1999-04-28 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emergence of a toxic organism like pfisteria in tributaries of the Chesapeake Bay has focused public attention on potential hazards in our water. More importantly, it has reminded us of the importance of the entire watershed to the health of any body of water and how political boundaries complicate watershed management. New Strategies for America's Watersheds provides a timely and comprehensive look at the rise of "watershed thinking" among scientists and policymakers and recommends ways to steer the nation toward improved watershed management. The volume defines important terms, identifies fundamental issues, and explores reasons why now is the time to bring watersheds to the forefront of ecosystem management. In a discussion of scale and scope, the committee examines how to expand the watershed from a topographic unit to a framework for integrating natural, social, and economic perspectives as they share the same geographic space. The volume discusses: Regional variations in climate, topography, demographics, institutions, land use, culture, and law. Roles and interaction of federal, state, and local agencies. Availability or lack of pertinent data. Options for financing. The committee identifies critical points in watershed planning to ensure appropriate stakeholder involvement and integration of science, policy, and environmental ethics.

This book was released on 2009 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: contributors - biologists, ecologists, geomorphologists, historians, hydrologists, lawyers, and political scientists - weave together threads from their diverse perspectives to reveal the processes that shape the past, present, and future of the San Pedro's riparian and aquatic ecosystems. They review the biological communities of the San Pedro and the stream hydrology and geomorphology that affects its riparian biota. They then look at conservation and management challenges along three sections of the San Pedro, from its headwaters in Mexico in its confluence with the Gila River, describing legal and policy issues and their interface with science; activities related to mitigation, conservation, and restoration; and a prognosis of the potential for sustaining the basin's riparian system." "Complemented by a foreword written by James Shuttleworth, these chapters demonstrate the complexity of the San Pedro's ecological and hydrological conditions, showing that there are no easy --
