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 Phytoplankton written by María Teresa Sebastiá and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytoplankton plays a key role in aquatic ecosystems where it is the major biomass producer. Phytoplankton is characterised by a high time-space variability which is determined by abiotic and biotic factors. In this book, the role of abiotic factors (light, temperature, nutrients, wind, hydrodynamics, CO2 and UV radiation) and biotic factors (bacteria, zooplankton, macrophytes and fish) is discussed. Anthropogenic pressure can alter those environmental factors, causing undesired changes in the composition and biomass of phytoplankton. This book emphasises the effects on water quality, but bottom sediment is also analysed. The effectiveness of management measures to restore impacted ecosystems is reviewed and ecological modelling is used as a prediction tool. In this book, the authors describe case studies in different systems such as natural lakes, reservoirs, marine systems and aquatic microcosm systems, covering a wide range of geographic areas from African tropical lakes and Brazilian subtropical lakes to peri-Alpine European lakes.

Download or read book Diagenetic Models and Their Implementation written by Bernard P. Boudreau and published by Springer. This book was released on 2011-10-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of sedimentary chemistry and its associated processes is becoming far more mathematical. This new emphasis is being driven by pressures originating from both basic research and field applications. There is a growing desire to gain a quantitative understanding of the reasons for the natural chemical changes observed in sediments as they are buried. Past textbooks have not emphasized the steps necessary to develop transport-reaction (diagenetic) models themselves nor methods for their solution. This book attempts to correct this situation by presenting a detailed account of model formulation by explaining some useful solution techniques. The choice of material illustrates methods that are simple to explain and implement, yet powerful enough to attack even the most complicated diagenetic problems. Computer programs that implement and illustrate the numerical methods are also made available.

Book excerpt: This condensed volume summarizes updated knowledge on the warm-monomictic subtropical Lake Kinneret, including its geophysical setting, the dynamics of physical, chemical and biological processes and the major natural and anthropogenic factors that affect this unique aquatic ecosystem. This work expands on a previous monograph on Lake Kinneret published in 1978 and capitalizes on the outcome of more than 40 years of research and monitoring activities. These were intensively integrated with lake management aimed at sustainable use for supply of drinking water, tourism, recreation and fishery. The book chapters are aimed at the limnological community, aquatic ecologists, managers of aquatic ecosystems and other professionals. It presents the geographic and geological setting, the meteorology and hydrology of the region, continues with various aspects of the pelagic and the littoral systems. Finally, the last section of the book addresses lake management, demonstrating how the accumulated knowledge was applied in order to manage this important source of freshwater. The section on the pelagic system comprises the heart of the book, addressing the major physical processes, external and internal loading, the pelagic communities (from bacteria to fish), physiological processes and the major biogeochemical cycles in the lake.
