Download or read book European Large Lakes written by Tiina Nõges and published by Springer Science & Business Media. This book was released on 2009-01-20 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Space on Earth written by Charles S. Cockell and published by Palgrave Macmillan. This book was released on 2006-11-28 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many environmentalists think going into space detracts from solving problems here on Earth. Many astrophysicists feel environmentalism hampers their exploration and settlement of space. Actually environmentalism and space exploration have one and the same objective, argues leading astro-biologist Professor Charles Cockell: to ensure humanity has a home. Cockell calls for a fusion of the two movements as the only way forward. The technologies we develop to live sustainably on Earth, such as wind and solar power, will also establish humanity in space. The exploration of space will provide new resources and skills for the protection of the Earth's environment. For example, studying extreme environments on Earth is helping us to look for life on Mars and satellites orbiting Earth are helping track hurricanes and protect people from natural disasters. There are many books on environmentalism and many on space faring. Space On Earth is the first to provide a new vision of humanity's future bringing these two goals together.

Download or read book Encyclopedia of Inland Waters written by and published by Academic Press. This book was released on 2009-01-13 with total page 2589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland aquatic habitats occur world-wide at all scales from marshes, swamps and temporary puddles, to ponds, lakes and inland seas; from streams and creeks to rolling rivers. Vital for biological diversity, ecosystem function and as resources for human life, commerce and leisure, inland waters are a vital component of life on Earth. The Encyclopedia of Inland Waters describes and explains all the basic features of the subject, from water chemistry and physics, to the biology of aquatic creatures and the complex function and balance of aquatic ecosystems of varying size and complexity. Used and abused as an essential resource, it is vital that we understand and manage them as much as we appreciate and enjoy them. This extraordinary reference brings together the very best research to provide the basic and advanced information necessary for scientists to understand these ecosystems – and for water resource managers and consultants to manage and protect them for future generations. Encyclopedic reference to Limnology - a key core subject in ecology taught as a specialist course in universitiesOver 240 topic related articles cover the field Gene Likens is a renowned limnologist and conservationist, Emeritus Director of the Institute of Ecosystems Research, elected member of the American Philosophical Society and recipient of the 2001 National Medal of Science Subject Section Editors and authors include the very best research workers in the field

Download or read book Neusiedlersee The Limnology of a Shallow Lake in Central Europe written by H. Löffler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: H. Laffler Interest aroused in the past by Neusiedlersee, located in what was earlier the western part of Hungary, was mainly due to the enormous fluctuations in water level and the consequent threat to the livelihood of the local popula tion, who lived chiefly from stock-farming. Practically no tourism touched the area until 1920, about a century later than Schubert's visit to the Salzkam mergut lake district, the traditional resort area in Upper Austria. Probably because of its small popularity there is almost no documentation in the form of engravings or paintings. One of the exceptions is an oil painting by Schnorr-Carolsfeld, from about 1820. It is obvious that there was no Phragmites at the time he painted the view near Neusiedl. When the shallow Neusiedlersee was discovered by tourists it began to attract scientific interest, although some earlier work by mineralogists, geographers and hydrographers does exist. But it was only after the Second World War that this interest could be intensified, the lake now being an alkaline, turbid body of water confined by the vast areas of Phragmites which had come into existence after the lake last dried out in 1868. Scientific work gained considerable impetus from international activities such as the Interna tional Biological Programme, International Hydrological Decade, and Man and Biosphere, the results of which will be included in this volume. But in spite of all such efforts Neusiedlersee will undoubtedly remain, in many respects, a mystery.
Download or read book Microbial Mats written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2010-07-17 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides information about microbial mats, from early fossils to modern mats located in marine and terrestrial environments. Microbial mats – layered biofilms containing different types of cells – are most complex systems in which representatives of various groups of organisms are found together. Among them are cyanobacteria and eukaryotic phototrophs, aerobic heterotrophic and chemoautotrophic bacteria, protozoa, anoxygenic photosynthetic bacteria, and other types of microorganisms. These mats are perfect models for biogeochemical processes, such as the cycles of chemical elements, in which a variety of microorganisms cooperate and interact in complex ways. They are often found under extreme conditions and their study contributes to our understanding of extremophilic life. Moreover, microbial mats are models for Precambrian stromatolites; the study of modern microbial mats may provide information on the processes that may have occurred on Earth when prokaryotic life began to spread.
