DOWNLOAD EBOOK →The monitoring of benthic diatoms, macrophytes, macroinvertebrates and fish will be the backbone of future water management in Europe. This book describes and compares the relevant methodologies and tools, based on a large data set covering rivers in most parts of Europe. The 36 articles presented will provide scientists and water managers with a unique insight into background and application of state-of-the-art monitoring tools and techniques.

DOWNLOAD EBOOK →This book reviews the latest research and developments concerning the biodiversity and biocontamination assessment of aquatic ecosystems in Poland. The authors present expert analyses of the current biological status of Polish surface waters, and examine a broad range of elements related to aquatic ecosystems, including macrophytes, phytoplankton, zooplankton and macroinvertebrates, microorganisms, fish, and selected invasive aquatic species. A set of conservation and restoration practices, and a review of protected sites within the Polish basins and catchment areas, are also provided. This book and the companion volume Polish River Basins and Lakes – Part I: Hydrology and Hydrochemistry offer valuable resources for students, environmental chemists, biologists, geologists, hydrologists and surface waters managers interested in the environmental conditions of Poland’s surface waters.

DOWNLOAD EBOOK →This book presents the results of thirty-four case studies in an EU-sponsored project on heavily modified water bodies. The account emphasizes the methods used in the process of identification and designation, and identifies further research needs. The contents are the basis for the agreed European Guidance on artificial and heavily modified water bodies to be used by practitioners in the implementation of the Water Framework Directive.

DOWNLOAD EBOOK →The dipteran family Chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments. A very wide range of gradients of temperature, pH, oxygen concentration, salinity, current velocity, depth, productivity, altitude and latitude have been exploited, by at least some chironomid species, and in grossly polluted environments chironomids may be the only insects present. The ability to exist in such a wide range of conditions has been achieved largely by behavioural and physiological adaptations with relatively slight morphological changes. It has been estimated that the number of species world-wide may be as high as 15000. This high species diversity has been attributed to the antiquity of the family, relatively low vagility leading to isolation, and evolutionary plasticity. In many aquatic ecosystems the number of chironomid species present may account for at least 50% of the total macroinvertebrate species recorded. This species richness, wide distribution and tolerance to adverse conditions has meant that the group is frequently recorded in ecological studies but taxonomic difficulties have in the past prevented non-specialist identification beyond family or subfamily level. Recent works, including genetic studies, have meant that the family is receiving much more attention globally.

DOWNLOAD EBOOK →In the context of freshwater fisheries changing their strategies from the regulation of harvest and the enhancement of populations, to the creation and protection of habitats and the management of ecosystems, moves toward establishing an aquatic habitat classification system. Eight papers, from the February 1988 Symposium on the Classification and Inventory of Great Lakes Aquatic Habitats (the last in a series of Great Lakes Symposia), propose various classification approaches, most using a limited number of physical, chemical, and/or biological variables to produce some form of index. They also include overviews and summaries of the classification process.

DOWNLOAD EBOOK →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.
