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.
Download or read book Integrated Study of Marine Mammals written by Suzy Bullock and published by . This book was released on 2017-06-02 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to study the vast field of marine mammals. The field is a study of marine or aquatic mammals that depends on ocean ecosystems and marine ecosystems for their survival. It has a compilation of topics that is varied in nature catering to the different needs of the readers. The book highlights the classification, evolution and the distribution of habitat of the marine mammals in detail. This text also elucidates strategies and tools to restore the marine mammals on the verge of extinction that are being used by scientists from all over the world. Through this book, we attempt to further enlighten the readers about the new concepts in this field.
Download or read book Fishes in Estuaries written by Michael Elliott and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: This landmark publication collates information and studies on the use of estuaries, and specific habitats within them, as nursery, feeding and refuge areas, and migration routes of marine and other fish, many of which are of commercial and conservation importance. The editors and authors of the book have carefully compiled a huge wealth of information from the work of 18 organizations across 11 countries, providing a unique collection of data never before brought together within the covers of one book. Chapters within this exceptional publication cover habitat use by fishes, recruitment and production in estuaries, links between fish and other trophic levels, endangered and rare species, estuarine development and restoration, environmental quality of estuaries and the management of estuarine fishes. The book notably contains extensive chapters on field methods and data analysis. Fishes in Estuaries is an essential tool and reference source for fisheries and environmental managers, fish biologists, environmental scientists, aquatic ecologists and conservation biologists. Libraries in all universities and research establishments where biological sciences are studied and taught should have copies of this book on their shelves, as should personnel employed in regulatory and consultant capacities, such as within rivers authorities, environment agencies and fish and wildlife departments. Comprehensive coverage of commercially exploited species. Internationally known and respected contributors. Multi-contributor approach providing very detailed coverage. Estuaries are a vitally important ecosystem.
