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, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal 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, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. 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.

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.

Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.

The second-longest European river after the Volga, the Danube is one of the world’s most important rivers in terms of its geographical and historical significance. In recent history, it has served as a major international waterway and numerous cities, including four capitals, have been founded on its banks. The 2826km-long Danube has a watershed measuring 801,093 km2 that is now shared between 19 countries, from its source in the Black Forest to the Black Sea, into which it pumps an average of 827 km3 of water a year. This book describes and explains key landscape values interactions (geographical, cultural and natural heritage). It also identifies the threats and various types of human impact affecting this system in all the countries of the Danube River Basin, based on the investigations and perspectives of a team of experienced naturalists, and in the context of the early 21st century, in which the human-nature relationship is still far from balanced. These studies demonstrate how biodiversity, conservation and ecological studies can help us successfully promote mutual cooperation and combine our efforts to address problems as a responsible continent.
