Optimal management of them requires a proper understanding of anthropogenic impacts both on the lake ecosystems as such and on the services they provide for society. The specific structural and functional properties of large lakes, e.g. morphology, hydrography, biogeochemical cycles and food-web structure, are all directly related to their size. Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered. These vulnerable ecosystems often suffer from accelerated eutrophication, over-fishing, toxic contamination and invasive species. Large lakes offer socio-economic benefits and can be used in many ways, and are often areas in which economic, cultural and political interests overlap. In this book the problems regarding the present status of European large lakes and the directions of change are discussed. Threats caused by direct human impact and by climate change, protection needs and restoration measures are considered Analysis zoetwaterecologie freshwater ecology mariene ecologie marine ecology milieubeheer environmental management milieumonitoring environmental monitoring environmental analysis Marine Ecology Mariene Ecologie Notes Cover title "The European Large Lakes Symposium (ELLS) 2006 ... took place in Tartu, Estonia, 11-15 September 2006"--Preface Bibliography Includes bibliographical references Notes Print version record Subject Lakes -- Europe -- Congresses Lakes -- Economic aspects -- Europe -- Congresses Lakes -- Social aspects -- Europe -- Congresses Lake ecology -- Economic aspects -- Europe -- Congresses Lake ecology -- Social aspects -- Europe -- Congresses Biomédecine.
