The rapid growth of the discipline of aquatic ecology has been driven both by scientific interest in the complexities of aquatic ecosystems and by their enormous environmental importance and sensitivity. This book focuses on the remarkably diverse roles played by underwater plants, and is divided into three parts: 10 thematic chapters, followed by 18 case studies, and rounded off by three integrative chapters. The topics range from macrophytes as fish food to macrophytes as mollusc and microbe habitat, making this of interest to aquatic ecologists as well as limnologists, ecosystem ecologists, microbial ecologists, fish biologists, and environmental managers.

The nutrient dynamics and biological structure of shallow non-stratified lakes differ markedly from that of deep and stratified lakes: for example, the return of nutrients lost through sedimentation is faster and the potential importance of fish and submerged macrophytes as food-web regulators is greater. In addition shallow lakes are more easily influenced by fluctuations in the physical environment caused by wind disturbance, temperature change, etc. Although shallow lakes are often the most common lake type in lowland countries, less attention has been paid to them than to deep stratified lakes and few comparisons have been made between shallow freshwater and brackish lakes. The volume is divided into five main themes, each introduced by an invited speaker: Nutrient dynamics with special emphasis on sediment water interactions and changes in loading (Professor Lambertus Lyklema); Biological structure and trophic interaction (Professor Stephen T. Threlkeld); Submerged macrophytes: dynamics and role in the lake ecosystems (Ass. Professor Kaj Sand Jensen); Comparison of freshwater and brackish lake ecosystems (Professor Brian Moss); Modelling the impact of nutrients, the biological structure and the recovery process (Dr Marten Scheffer).

This volume comprises the proceedings of the 5th International Symposium on Shallow Lakes, held at Dalfsen, The Netherlands, in June 2005. The theme of the symposium was Shallow Lakes in a Changing World, and it dealt with water-quality issues, such as changes in lake limnology, especially those driven by eutrophication and pollution, increased nutrient loading and productivity, perennial blooms of cyanobacteria and loss of biodiversity.

The Ecological Bases for Lake and Reservoir Management provides a state-of-the-art review of the range of ecologically-based techniques necessary for the holistic management of lakes and their catchments. Most of the methods, case studies and national policies reviewed are directed towards management of the largest problem - eutrophication - with the emphasis on the multiple-scale approach needed for successful management and restoration. Case studies come from the USA and ten European countries, and range from single lakes through to lake districts and national inventories. Several essays precede the practical chapters with thought-provoking comments on the political, social and economic climate of water management.

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.

Organic matter in aquatic environments consists mostly of large compounds which cannot be taken up and utilized directly by microbial cells. Prior to incorporation, polymeric materials undergo degradation by cell-bound and extracellular enzymes produced by these microbes; in fact, such enzymatic mobilization and transformation is the key process which regulates the turnover of organic as well as inorganic compounds in aquatic environments. This volume brings together studies on enzymatic degradation processes from disciplines as diverse as water and sediment research, bacterial and algal aquatic ecophysiology, eutrophication, and nutrient cycling and biogeochemistry, in both freshwater and marine ecosystems. Its scope extends from fundamental research exploring the contribution of microbial enzymatic processes to whole ecosystem functioning to practical applications in water biotechnology. The first comprehensive publication providing an overview of this emerging field of enzymology, Microbial Enzymes in Aquatic Environments will be of great interest to ecologists and microbiologists alike.

It has been more than ten years since the last edition of the bestselling Restoration and Management of Lakes and Reservoirs. In that time, lake and reservoir management and restoration technologies have evolved and an enhanced version of this standard resource is long overdue. Completely revised and updated, the third edition continues the tradition of providing comprehensive coverage of the chemical, physical, and biological processes of eutrophication and its control. The authors describe the eutrophication process, outline methods for developing a pre-management and restoration diagnosis-feasibility study, and provide detailed descriptions of scientifically sound management and restoration methods. See what’s new in the Third Edition: • New chapters on aquatic plant ecology and management • Emphasis on freshwater availability • A regional framework for water quality attainment • Methods of lake and reservoir restoration and management • Updates or revisions to all other chapters The book features in-depth discussions of techniques used to manage eutrophication in standing water bodies, procedures for using these techniques, the principles involved, and successes and failures through a selection of case studies and cost analyses. Each chapter includes an introduction to the scientific basis of the problem, a description of the methods and procedures, and presents several case histories. Potential negative impacts and costs, where known, are described. A useful classroom text, reference manual, and general guide, this is the text against which all other resources in this field are measured.

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.
