Book excerpt: As with all ecosystems, river systems involve a complex interaction of a rich diversity of micro-organisms, plants and animals with their physical and chemical environment. The river habitat presents unique problems for organisms exposed to unidirectional currents, seasonal variation in flow, and disturbance due to pollution and other human interference. The book starts with a description of the taxa, their adaptations and their ecologies, followed by chapters describing the ecosystem processes in terms of trophic interactions and the key production processes related to photosynthesis and decomposition. A major chapter then considers the principles, practices and problems associated with making reliable observations on river organisms, leading to final chapters investigating how river biota are impacted by human activity and how, in turn, they can be used as indicators of these effects in river-management programmes.

Download or read book Algae Abstracts written by Office of Water Resources Research Staff and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aigae Abstracts is the first in aseries of bibliographies on water re sources and pollution published by IFI/Plenum Data Corporation in cooperation with the Water Resources Scientific Information Center (WRSIC). It is produced wholly from the information base compris ing material abstracted and indexed for Selected Water Resources Abstracts. The bibliography is divided into volumes according to the publication dates of the source documents. Volume 1 contains 569 abstracts cov ering publication dates up to and including 1969; Volume 2 contains 730 abstracts covering the years 1970 to 1972. The material included in this bibliography represents computer selections based on the presence of a form of the word "alga" somewhere in the referenced citation. Substantively, the material typifies WRSIC's "centers of com petence" approach to information support of the Office of Water Re sources Research (OWRR) of the Department of the Interior. Most of the references in this bibliography are the work of the center of competence on eutrophication at the University of Wisconsin. The indexes refer to the WRSIC accession number, which follows each abstract. The Significant Descriptor Index is made up of a fraction of the total descriptors and identifiers by which each paper has been indexed. It represents weighted terms that best describe the informa tion content; this status is indicated by the asterisks which precede them. The General Index includes all the remaining descriptors and identifiers by which each paper in this bibliography has been indexed.

Download or read book Lake and Reservoir Restoration written by G. Dennis Cooke and published by Elsevier. This book was released on 2013-10-22 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.

Download or read book Biology, Ecology and Management of Aquatic Plants written by Joseph Caffrey and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical and physical, and biological and biomanipulation. This series of papers from over 20 different countries was generated from the tenth in the highly successful series of European Weed Research Society symposia on aquatic plant management, this being the tenth. It provides a valuable insight into the complexities involved in managing aquatic systems, discusses state-of-the-art control techniques and deals with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.
