Saline Lakes Around the World
Author: Lake Biwa: Interactions between Nature and People
Author: Hiroya KawanabePublisher: Springer Science & Business Media
ISBN: 9400717830
Category : Science
Languages : en
Pages : 716
Book Description
This book focuses on the long-term interactions between people and nature in and around Lake Biwa, one of the oldest lakes in the world. Accordingly, it not only covers the characteristics of the biota of this ancient lake, but also approaches it as a ‘cultural ancient lake.’ Furthermore, various problems affecting the lake, especially recent environmental changes that occurred before and after Japan’s rapid economic growth of the 1950s and 60s, are reviewed, including water pollution, lakeshore development and the reclamation of attached lakes, alien and invasive species, and problems related to the recent warming of the climate. Lastly, by analyzing data on these problems collected by the local government and residents of the lake basin, the book provides a comprehensive outlook on the future of Lake Biwa and people’s lifestyles. As such, it provides indispensable information for all people engaged in improving and conserving water regimes around the world, as well as people interested in the culture and history of Japan.
Restoration of Aquatic Ecosystems
Author: National Research CouncilPublisher: National Academies Press
ISBN: 9780309045346
Category : Technology & Engineering
Languages : en
Pages : 580
Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
Eutrophication: causes, consequences and control
Author: Abid A. AnsariPublisher: Springer Science & Business Media
ISBN: 9048196256
Category : Technology & Engineering
Languages : en
Pages : 402
Book Description
Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.
Freshwater Biodiversity
Author: David DudgeonPublisher: Cambridge University Press
ISBN: 1108882625
Category : Nature
Languages : en
Pages : 517
Book Description
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
Ecosystems of California
Author: Harold MooneyPublisher: Univ of California Press
ISBN: 0520278801
Category : Nature
Languages : en
Pages : 1008
Book Description
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.

Real-time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms
Author: Babin, MarcelPublisher: UNESCO
ISBN: 9231040421
Category : Nature
Languages : en
Pages : 880
Book Description
The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.
