The vast majority of the world's lakes are small in size and short lived in geological terms. Only 253 of the thousands of lakes on this planet have surface areas larger than 500 square kilometers. At first sight, this statistic would seem to indicate that large lakes are relatively unimportant on a global scale; in fact, however, large lakes contain the bulk of the liquid surface freshwater of the earth. Just Lake Baikal and the Laurentian Great Lakes alone contain more than 38% of the world's total liquid freshwater. Thus, the large lakes of the world accentuate an important feature of the earth's freshwater reserves-its extremely irregular distribution. The energy crisis of the 1970s and 1980s made us aware of the fact that we live on a spaceship with finite, that is, exhaustible resources. On the other hand, the energy crisis led to an overemphasis on all the issues concerning energy supply and all the problems connected with producing new energy. The energy crisis also led us to ignore strong evidence suggesting that water of appropriate quality to be used as a resouce will be used up more quickly than energy will. Although in principle water is a "renewable resource," the world's water reserves are diminishing in two fashions, the effects of which are multiplicative: enhanced consumption and accelerated degradation of quality.

Why study a small lake in the White Mountains of north-central New Hamp shire? Better yet, why write a book about those studies? We wrestled with such questions for years, and the answers lie in the overall ecosystem focus and approach we have taken. At the same time that we studied Mirror Lake, numerous and comprehensive studies were done of the surrounding terres trial and stream ecosystems of the Hubbard Brook Valley. These associated studies complemented those done in the lake and provided unique informa tion about air-land-water linkages in the Valley. Many of the studies con ducted in Mirror Lake were about organisms or about the processes carried out by these individual organisms or communities. Nevertheless, an abiding objective always was to determine the significance that these individuals and individual processes had to the overall structure, metabolism and biogeo chemistry of the Mirror Lake ecosystem. To wit, what is the significance for the ecosystem? In some cases the ecosystem role was clear, for many it was not. But the hope is that our attempts to unravel and understand the whole will be informative and, more importantly, that it will stimulate others to study the holistic and functional relationships in entire landscapes. The book is more than a case history of a single lake. We have written it not only for the serious student of lakes, but also for those interested in ecosystems and their interactions.

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.

"Two whole lake experiments are describes : experimental acidification at Little Rock Lake and the response of Lake Mendota to a natural experiment involving agricultural and urban development. Readers will learn the benefits of doing long-term ecological research, and limnologists will discover the richness of new information derived from studying suites of neighboring lakes across time."--BOOK JACKET.

This book gives a comparative treatment of topics accross lake, reservoir, and rive ecosystems. These analysis do indeed indicate differences among the properties of lakes, land-water interface regions, reservoirs, and rivers. Importantly, these analysis also indicate marked commonality in function.

Large lakes are important because of their size and ecological distinctiveness as well as their economic and cultural value. Optimal management of them requires a proper understanding of anthropogenic impacts both on the lake ecosystems as such and on the services they provide for society. The specific structural and functional properties of large lakes, e.g. morphology, hydrography, biogeochemical cycles and food-web structure, are all directly related to their size. Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered. These vulnerable ecosystems often suffer from accelerated eutrophication, over-fishing, toxic contamination and invasive species. Large lakes offer socio-economic benefits and can be used in many ways, and are often areas in which economic, cultural and political interests overlap. In this book the problems regarding the present status of European large lakes and the directions of change are discussed. Threats caused by direct human impact and by climate change, protection needs and restoration measures are considered.
