Available in PDF, EPUB and Kindle. Book excerpt: The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Available in PDF, EPUB and Kindle. Book excerpt: Until recently, the prevailing view of marine life at high latitudes has been that organisms enter a general resting state during the dark Polar Night and that the system only awakens with the return of the sun. Recent research, however, with coordinated, multidisciplinary field campaigns based on the high Arctic Archipelago of Svalbard, have provided a radical new perspective. Instead of a system in dormancy, a new perspective of a system in full operation and with high levels of activity across all major phyla is emerging. Examples of such activities and processes include: Active marine organisms at sea surface, water column and the sea-floor. At surface we find active foraging in seabirds and fish, in the water column we find a high biodiversity and activity of zooplankton and larvae such as active light induced synchronized diurnal vertical migration, and at seafloor there is a high biodiversity in benthic animals and macroalgae. The Polar Night is a period for reproduction in many benthic and pelagic taxa, mass occurrence of ghost shrimps (Caprellides), high abundance of Ctenophores, physiological evidence of micro- and macroalgal cells that are ready to utilize the first rays of light when they appear, deep water fishes found at water surface in the Polar night, and continuous growth of bivalves throughout the winter. These findings not only begin to shape a new paradigm for marine winter ecology in the high Arctic, but also provide conclusive evidence for a top-down controlled system in which primary production levels are close to zero. In an era of environmental change that is accelerated at high latitudes, we believe that this new insight is likely to strongly impact how the scientific community views the high latitude marine ecosystem. Despite the overwhelming darkness, the main environmental variable affecting marine organisms in the Polar Night is in fact light. The light regime during the Polar Night is unique with respect to light intensity, spectral composition of light and photoperiod.

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.
