This book was released on 2006-03-30 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarises investigations on Lake Verevi (surface 12.6 ha, mean depth 3.6 m), located in the Estonian town of Elva, initiated since 1929. The seventeen articles deal with a wide range of questions, starting with a holistic overview of the ecological status, over assessments of long-term changes in biotic and abiotic conditions and finishing with proposed restoration plans. Abiotic chapters provide calculations on water and mass balance, distribution and fractions of phosphorus in the sediment, optical properties and penetration of radiation in the water column, sedimentation rate during the formation of stratification, and nitrogen circulation characteristics. All these phenomena explain the special environmental features of this highly stratified lake. Long-term changes, seasonal development, primary production and resource ratios inducing the distribution of species composition of various biota (bacterio-, phyto and zooplankton, periphyton, macrovegetation, macrozoobenthos, fish) are discussed. The most important issues are long-term investigations on a complex ecosystem, the phenomenon of partial meromixis, the description of restoration methods, and the existence of narrow microniches for plankton in the water column. The volume firmly establishes Lake Verevi as a model system of a natural aquatic habitat, experiencing a multitude of anthropogenic pressures, but for which restoration plans aim to provide sustainable management in the future.

Download or read book Hydrological and Limnological Aspects of Lake Monitoring written by Pertti Heinonen and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides an extensive overview of all the most important aspects of lake monitoring studies describing methods of water sampling, analytical determination and data interpretation. Now that all EC countries must receive the EC Directive on Water Quality, there is a greater need to improve the quality of measurements, both in chemical and biological fields and this book describes the best practices in measuring water, quality, standard procedures and quality assurance in relation to current legislation and guidelines. The book provides coverage of: ? Abiotic processes and harmful substances in lakes ? Biocoenosis in evaluating the ecological status of lakes ? New lake monitoring techniques ? Quality assessment ? Managing of results The book also addresses the most important problems currently impacting lake resources: ? Eutrophication ? Water acidification and its impact on biodiversity ? The presence of endocrine disrupters ? The bioaccumulation of mercury in the food chain This is an essential guide to the subject for postgraduate students in environmental science and analytical chemistry, laboratories involved in water analysis, industrial companies producing effluent and regional environmental agencies. 'Hydrological and Limnological Aspects of Lake Monitoring' is the first book in the Water Quality Measurement Series, which provides a comprehensive coverage of the analytical techniques used for the measurement of substances in water, from sampling through to laboratory analysis. The series aims to offer practical answers to specific issues related to measurements of the water cycle quality, using a scientifically sound approach.

Download or read book Shallow Lakes 95 written by Lech Kufel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shallow lakes differ from deep ones in many aspects of nutrient dynamics, biotic structure and interactions of various trophic levels. Though very common in European lowlands, shallow lakes attract inadequate attention from research teams. This book aims at filling gaps in our knowledge of the processes which take place in non-stratified lakes. It contains proceedings from the international conference `Shallow Lakes *95' held in Mikolajki, Poland, on 20-26 August 1995. In more than 50 original papers up-to-date views on eutrophication, degradation and recovery of shallow lakes are presented. The first four sections of the book (Nutrient fluxes, Biotic structure, Trophic interactions and Whole lake studies) deal with theoretical aspects of lake functioning while the fifth (Biomanipulation, restoration and management) is devoted to practical measures undertaken to improve water quality in shallow lakes. The book is therefore addressed to university biologists and ecologists and PhD students, as well as to managers involved in restoration of shallow lakes.
