Written from an ecosystem perspective, this user-friendly and thorough book discusses, without the use of jargon, events that happen below the waterline of lakes, rivers, and wetlands and links them back to the attributers of the drainage basins, the overlying atmosphere and climate, which have a major impact on inland waters and their biota. It also contains a large number of easy-to-comprehend figures and tables that reinforce the written material and provide evidence for statements made. The focus on how fundamental limnology applies to environmental management and conservation shows readers that fundamental science can (and does) make a major contribution to solving environmental problems. Chapters 1 and 2 provide a background and history of limnology. Patterns are based on data and photos from all over the world. Emphasis placed on the role of drainage basins, the atmosphere, contaminants, weather and climate — in determining the function of aquatic systems. Chapters on acidifying precipitation, organic and trace metal contaminants, and reservoirs integrates the individual topics discussed in the different chapters by bringing it to bear on three major environmental issues. Emphasis on the importance of the spatial, temporal, and interval scales over which research is carried out and conclusions are drawn and the difficulty of “scaling up” findings. For further study by those with limnology or aquatic management and conservation

Intended for biology and environmental sciences students, this study of lake systems covers the physics, chemistry and biology of lakes. The text includes ecosystem examples to illustrate basic concepts in limnology. The examples are drawn from all over the world - Africa, the Americas, Antarctica, the Arctic, Europe, Japan and New Zealand. This wide array of examples allows the authors to point out marked differences in size, basin shape, climate and biota, while illustrating a unity of principles in limnology. The number of topics is limited so that major subjects - such as physical conditions within lake systems, applications to the LIST environment, and the success of big rivers, streams and estuaries - can be covered in more depth.

Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.

To fulfill its commitment to clean water, the United States depends on limnology, a multidisciplinary science that seeks to understand the behavior of freshwater bodies by integrating aspects of all basic sciences--from chemistry and fluid mechanics to botany, ichthyology, and microbiology. Now, prominent limnologists are concerned about this important field, citing the lack of adequate educational programs and other issues. Freshwater Ecosystems responds with recommendations for strengthening the field and ensuring the readiness of the next generation of practitioners. Highlighted with case studies, this book explores limnology's place in the university structure and the need for curriculum reform, with concrete suggestions for curricula and field research at the undergraduate, graduate, and postdoctoral levels. The volume examines the wide-ranging career opportunities for limnologists and recommends strategies for integrating limnology more fully into water resource decision management. Freshwater Ecosystems tells the story of limnology and its most prominent practitioners and examines the current strengths and weaknesses of the field. The committee discusses how limnology can contribute to appropriate policies for industrial waste, wetlands destruction, the release of greenhouse gases, extensive damming of rivers, the zebra mussel and other "invasions" of species-- the broad spectrum of problems that threaten the nation's freshwater supply. Freshwater Ecosystems provides the foundation for improving a field whose importance will continue to increase as human populations grow and place even greater demands on freshwater resources. This volume will be of value to administrators of university and government science programs, faculty and students in aquatic science, aquatic resource managers, and clean-water advocates--and it is readily accessible to the concerned individual.
