Download or read book The Estuarine Ecosystem written by Donald S. McLusky and published by OUP Oxford. This book was released on 2004-04-29 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the inhabitants of many of the world's major towns and cities, estuaries provide their first and nearest glimpse of a natural habitat. Despite the attempts of man to pollute or reclaim it, the estuarine ecosystem continues to provide a fascinating insight into a natural world where energy is transformed from sunlight into plant material, and then through the steps of a food chain is converted into a rich food supply for birds and fish. The book provides a concise readable introduction to estuarine ecology. First published in 1981, it soon established itself as the principle textbook of choice in the UK & NW Europe. This new edition builds upon the strengths of the earlier editions but has been thoroughly revised throughout. The new co-author brings a human impact dimension to the revised book. It is written for advanced undergraduate and graduate students (particularly taught masters) who have had a general ecology course, but no further training in estuarine science. It will be useful to both professional researchers and practical managers in marine ecology and environmental science who seek a compact but comprehensive introduction to estuarine ecology.

Available in PDF, EPUB and Kindle. Book excerpt: For the inhabitants of many of the world's major cities and towns, estuaries provide their nearest glimpse of a natural habitat; a habitat which, despite the attempts of man to pollute it or reclaim it, has remained a fascinating insight into a natural world where energy is transformed from sunlight into plant material, and then through the steps of a food chain is converted into a rich food supply for birds and fish. The biologist has become interested in estuaries as areas in which to study the responses of animals and plants to severe environmental gradients. Gradients of salinity for example, and the problems of living in turbid water or a muddy substrate, prevent most animal species from the adjacent sea or rivers from entering estuaries. In spite of these problems, life in estuaries can be very abundant because estuarine mud is a rich food supply which can support a large number of animals with a large total weight and a high annual production. Indeed estuaries have been claimed to be among the most productive natural habitats in the world. When the first edition of this book appeared, biologists were beginning to realise that the estuarine ecosystem was an ideal habitat in which to observe the processes controlling biological productivity.

Available in PDF, EPUB and Kindle. Book excerpt: By 1988 the Handbook of Vegetation Science is well on its way to completion. With 7 volumes in circulation, 3 volumes in the press, and most of the remaining volumes in preparation it appears that the total task can be completed in the early 'nineties. I am especially thankful to Professor Symoens for accepting the task of editing the volume on aquatic vegetation. The main emphasis of work in phytosociology is devoted to land plants, yet the landscape analysis remains incomplete without the consideration of rivers and lakes. Avolume on inland aquatic vegetation must therefore be most helpful to the land vegetation analyst and not only to the specialist on aquatic vegetation. Professor Symoens succeeded in drafting the most competent team for his task. I am sure that all colleagues working in vegetation analysis will be grateful to them that they have taken the time and energy to complete their chapters. Handbook articles are not easy to write and certainly not easy to edit. in the landscape are treated. The The major aquatic components vegetation analysts will welcome the fact that certain physiological and ecological processes of water plants are covered for which otherwise they would have to consult the limnological literature. This volume, together with the forthcoming volume on wetlands, should completely cover the inland aquatic vegetation problematic.

This book was released on 2020-06-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic plants refer to a diverse group of aquatic photosynthetic organisms large enough to be seem with the naked eye, and the vegetative parts of which actively grow either permanently or periodically (for at least several weeks each year) submerged below, floating on, or growing up through the water surface. These include aquatic vascular plants, aquatic mosses and some larger algae. Aquatic plants are grouped into life forms, each of which relates differently to limiting factors and has distinct ecological functions in aquatic ecosystems. Life form groups include emergent macrophytes (plants that are rooted in sediment or soils that are periodically inundated, with all other structures extending into the air), floating-leaved macrophytes (rooted plants with leaves that float on the water surface), submersed macrophytes (rooted plants growing completely submerged), free submerged macrophytes (which are not rooted but attached to other macrophytes or submerged structures) and free-floating macrophytes (plants that float on the water surface). Aquatic plants play an important role in the structure and function of aquatic ecosystems by altering water movement regimes, providing shelter and refuge and serving as a food source. In addition, aquatic plants produce large standing crops which can also stabilize sediments, accumulate large amounts of nutrients thus improving water healthy. Thus, because of their ecological role, aquatic plants are an important component of aquatic ecosystems. Aquatic plants are very vulnerable to human activities and global changes, and many species of the plants had become endangered in the past several decades due to habitat loss, flooding, damming, over foraging, biological invasion and eutrophication, which might not be halted but enforced in the future when more extreme weathers coincide with enhanced human activities.

Download or read book Management and Ecology of Freshwater Plants written by Joseph Caffrey and published by Springer. This book was released on 2011-12-10 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal 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, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. 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.
