Download or read book Shallow Lakes 98 written by Norbert Walz and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume combines articles on shallow lakes from leading European scientists in limnology. It covers aspects of the dynamics of macrophytes, phytoplankton, zooplankton and benthos, nutrient loading, littoral-pelagic interactions, and sediment-water interactions, as well as lake management. The object was not to separate theory (e.g. modelling) and management in order to generate new theories for the understanding of shallow lake ecosystems. The volume provides a comprehensive overview of the ecology of shallow lakes, a lake type which differs in prominent ways from deeper lakes. The broad spectrum of issues may also reflect the spectrum of interested readers such as limnologists, water engineers, hydrobiologists, who will be informed on a high level about new developments.

Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Internal Phosphorus Loading in Lakes written by Bryan Spears and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrient enrichment of lakes is a ubiquitous problem, impacting ecological and human health on a global scale by accelerating the pace of eutrophication, often resulting in algal blooms, depleted dissolved oxygen concentrations, and economic harm to surrounding communities. In many lakes, bed sediments are a major but unrecognized source of phosphorus to the water, a process known as internal phosphorus loading. Internal loading is notoriously difficult to measure and manage given the need to access processes operating on and within the lakebed. In addition, climate change threatens to promote internal loading. For example, warming of lakes can increase the release of phosphorus from sediments due to 1) longer and stronger periods of lake stratification resulting in sediment anoxia and 2) enhanced microbial decomposition of organic matter. Degraded water quality not only impairs ecological health but also can influence social pride and community morale. This is the first book dedicated to the understanding of internal phosphorus loading in lakes and examines the causes, the ecological and societal impacts, and options for managing this complex phenomenon. With contributions from leading experts, this edited volume provides a broad view of internal phosphorus loading, methods for measurement, management practices for water quality improvement, case studies from around the world, and recommendations for addressing this growing concern. It is essential reading for environmental and engineering professionals involved in lake and reservoir management, students and faculty in limnology, state and federal authorities involved in water quality regulation, and lakefront homeowners and management boards interested in maintaining lake water quality and managing algal blooms. Key Features * First-ever comprehensive volume on internal phosphorous loading that clearly details what it is and why it occurs * Identifies and explores the drivers of internal phosphorus loading * Provi

Download or read book Freshwater Algae of North America written by John D. Wehr and published by Elsevier. This book was released on 2002-12-15 with total page 935 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater algae are among the most diverse and ubiquitous organisms on earth. They occupy an enormous range of ecological conditions from lakes and rivers to acidic peat swamps, inland saline lakes, snow and ice, damp soils, wetlands, desert soils, wastewater treatment plants, and are symbionts in and on many plants, fungi, and animals. In North America, the variety of freshwater habitats colonized by algae is very rich, and offers an enormous and fascinating range of environments for their study. They form the base of most aquatic food webs and are critical to studies of ecosystem health. Algal ecologists and taxonomists play an important role in the understanding of aquatic ecosystems: their biodiversity, productivity, interactions with other organisms, and water quality. This book provides in one volume a practical and comprehensive guide to the genera of freshwater algae known from North America. The format combines the necessary ecological, taxonomic and methodological information for all scientists working in aquatic environments, whether their specialty is in environmental monitoring and water quality assessment, biological composition, ecology, evolution, or molecular biology.Key Features* The first complete accounting of North America's freshwater algal genera in more than 50 years* Includes a guide to the current literature on species identification in each group of algae* High-quality photographs and drawings of more than 770 genera* A clear, easy-to-use introductory key to the diagnostic chapters* Synthetic chapters on freshwater habitats, use of algae in environmental assessment, and control of nuisance algae* Contributions from 27 experts in all areas of freshwater algae* Extensive literature citations* Companion volume of Ecology and Classification of North American Freshwater Invertebrates 2nd edition, edited by Throp and Covich
