Originally published in 1987, this book describes and discusses the vegetation of rivers and other watercourses in Europe with an emphasis upon distributional, community and historical ecology. It was firmly based upon many years of field investigations carried out by the author in various countries in the European Economic Community. The main purpose of the text was to increase the understanding of river vegetation in relation to the varying physical characteristics of the watercourses. The rivers of the EEC are considered in detail, with an emphasis upon the influences of landscape, geology, climate, settlement patterns, water use and management and pollution. This book will be of value to anyone with an interest in river botany.

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.

A distinguished team of Western European scholars has written an advanced, full-length physical geography designed to be a state-of -the-art evaluation of the physical environment of Western Europe, being both retrospective and prospective in its perception of environmental change. The unique natural and regional environments of Western Europe are discussed, as well as the physical geographic framework of the region. Particular emphasis is placed on the impact and responses of human society on the physical environment of the region which is characterized by a very high population density. As an enhanced reference work it will be of enduring value.

As with all ecosystems, river systems involve a complex interaction of a rich diversity of micro-organisms, plants and animals with their physical and chemical environment. The river habitat presents unique problems for organisms exposed to unidirectional currents, seasonal variation in flow, and disturbance due to pollution and other human interference. The book starts with a description of the taxa, their adaptations and their ecologies, followed by chapters describing the ecosystem processes in terms of trophic interactions and the key production processes related to photosynthesis and decomposition. A major chapter then considers the principles, practices and problems associated with making reliable observations on river organisms, leading to final chapters investigating how river biota are impacted by human activity and how, in turn, they can be used as indicators of these effects in river-management programmes.

The first comprehensive guide to the aquatic plants of the region Beneath the surface of bodies of freshwater—springs, streams, rivers, ponds and lakes—there is a world of plants of great variety and beauty, a realm that is often poorly known and understood. Correctly identified, these plants can tell us much about the character and condition of the habitats in which they live. A collaboration of Danish, German, and British field botanists specializing in freshwater plants, this guide presents all of the known aquatic plants of Northern and Central Europe, including Britain and Ireland, as well as many marginal and wetland species. This is the first comprehensive guide to the identification of the region’s 410 species and hybrids of both native and non-native ferns and flowering plants that are dependent upon freshwater wetlands. Following the latest taxonomy, the book features 358 plates in pen and ink, more than 1,400 colour photographs, illustrated keys, distribution maps and detailed descriptions. The introduction gives an overview of evolution, anatomy and morphology, ecology, eco-physiology, research traditions and more, and the book also includes guidelines for working with aquatic plants. The first comprehensive guide to the region’s aquatic plants Covers all 410 known species Features 358 illustrated plates, more than 1,400 colour photographs, distribution maps, detailed descriptions and much more
