The loss to national economies resulting from excessive plant biomass has been appreciable and has put pressure on water managers to develop weed control procedures. The results from the most up-to-date research activities and field trials of leading aquatic plant scientists and managers in all five continents, aimed at resolving these weed problems, has been drawn together in this volume.

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.

Given the essential role that primary producers play in aquatic ecosystems, it is imperative that the potential risk of pesticides to the structure and functioning of aquatic plants is adequately assessed. An integration of regulatory and research information from key specialists in the area of environmental regulation, Aquatic Macrophyte Risk Asse

This book is a comprehensive collection of information about the features, functions, and services of aquatic macrophytes. As primary producers, aquatic macrophytes form the basis of food webs, play a major role in highly productive aquatic ecosystems, and have a significant impact on ecosystem functions and services. Macrophytes are also known to strongly influence the micro-climate and biogeochemical processes occurring in the littoral zones of marine ecosystems and the sediment dynamics of freshwater systems. They also serve as highly effective carbon sinks and play an important role in carbon sequestration. This book deals with various aspects of aquatic macrophytes, including nutrient recycling, biogeochemical processes, biomass production, wetland ecosystems, water resource management, carbon sequestration, environmental clean-up, and bioenergy production. Additionally, it presents the current status of aquatic macrophytes and discusses the impact of climate change on these plants. The book also highlights the major challenges associated with harnessing the benefits provided by aquatic macrophytes as ecosystem services. The book holds value and relevance for academicians and scientists working in the related domain. Additionally, it will serve as a valuable resource for students and researchers working in the field of ecology, biogeochemistry, wetland conservation, phytoremediation, elements biomonitoring, wastewater management, bioenergy production, etc.

This book offers a comprehensive study of species- and genus-level diversity and chorology of the global freshwater fauna to date. It gives a state of the art assessment of the diversity and distribution of Metazoa in the continental waters of the world.

Contamination of the different components of environment through industrial and anthropogenic activities have guided new eras of research. This has lead to development of strategies/methodologies to curtail/minimize environmental contamination. Research studies conducted all over the globe established that bioremediation play a promising role in minimizing environmental contamination. In the last decade, phytoremediation studies have been conducted on a vast scale. Initial research in this scenario focused on screening terrestrial plant species that remove contaminants from soil and air. Later, scientific community realized that water is a basic necessity for sustaining life on earth and quality of which is getting deteriorated day by day. This initiated studies on phytoremediation using aquatic plants. Role of aquatic plant species in cleaning water bodies was also explored. Many of the aquatic plant species showed potential to treat domestic, municipal and industrial wastewaters and hence their use in constructed wetlands for treating wastewaters was emphasized. The present book contains five chapters. First two chapters provide information about types of contaminants commonly reported in wastewaters and enlists some important and well studied aquatic plant species known for their potential to remove various contaminants from wastewater. Subsequent chapters deal with mechanisms involved in contaminant removal by aquatic plant species, and also provide detailed information about role of aquatic plant species in wetlands. Potential of constructed wetlands in cleaning domestic and industrial wastewaters has also been discussed in detail. The strategy for enhancing phytoremediation capacity of plants by different means and effectiveness of phytoremediation technology in terms of monitory benefits has been discussed in last chapter. Last chapter also emphasizes the future aspects of this technology.

This literature review has been compiled in response to a request for an update on interactions between aquatic macrophytes and fish and aims to assist fishery planners, managers, field specialists and other interested in this topic. The sources are listed in full.
