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.

Proceedings of the 17th BMB Symposium, 25-29 November 2001, Stockholm, Sweden

This book tells a story of a large lake affected by agricultural and urban activities that have led to severe eutrophication problems with nuisance blue-green algal blooms.

Proceedings of the 31st European Marine Biology Symposium, held in St. Petersburg, Russia 9-13 September 1996

A compilation of refereed papers from the International Symposium held in St. Petersburg, Russia, September 12-17, 1994

Proceedings of the First International Conference held in Lancaster, England, July 11-14, 1988

This work presents the state of the art of aquatic and semi-aquatic ecological restoration projects in The Netherlands. Starting from the conceptual basis of restoration ecology, the successes and failures of hundreds of restoration projects are described.

This book will be of interest to researchers in the field of aquatic ecology, river system functioning, and water surface pollution, to postgraduate students, to the institutions involved in water resource management, and to the drinking water and waste water treatment industries.

Rivers around the world are threatened by changes in land use, climate, hydrological cycles, and biodiversity. This book explores a wide range of determining factors that feed in to global change and examines the impact they have on river ecosystems.

Proceedings of the Second International Symposium on Cladocera, Tatranska Lomnica, Czechoslovakia, September 13-20, 1989

In July 2001 experts from all around the world met in Reykjavik, Iceland to discuss various issues of polychaete biology. In particular the latest developments in cladistic inference of polychaete phylogeny were presented.

Proceedings of the Second International Sediment/Freshwater Symposium held in Kingston, Ontario, June 15-18, 1981

Wetlands could be described as land and water at Tropical wetlands: one and the same time, and as such are very specific on the brink ecosystems. Whatever the reasons, often perceived as obstacles to human development many tropical wetlands still exist and support the and well-being.

Proceedings of the Third International Symposium on Cladocera, Bergen, Norway, 9--17 August 1993

In this age of increased fundamental and applied research on biodiversity, no single volume was as yet devoted to the various temporal and spatial aspects of aquatic biodiversity.
