This book was released on 1995-11-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nineteen papers representing the results of a project funded by the Commission of the European Communities to study macrotidal estuaries from the Elbe to the Tagus in a comparative and coherent manner by way of a standardized methodology. The papers address topics in primary production, bacterial processes, zooplankton, hyperbenthos, meiobenthos, macrobenthos, and modeling. A major result of the comparison is that salinity gradients explain species succession within each estuary, yet similar succession series are found at different salinity levels in different estuaries. The volume is reprinted from Hydrobiologia, v.311, 1995. Includes graphs and maps. Lacks an index. Annotation copyright by Book News, Inc., Portland, OR

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. When the previous editions of this book appeared, biologists were beginning to realize that the estuarine ecosystem was an ideal habitat in which to observe the processes controlling biological productivity. In the intervening period, many more estuaries and their inhabitants have been studied intensively. It is now possible to answer many of the questions posed by the earlier editions, and to pursue further the explanation of high productivity in estuaries and of energy utilization at different trophic levels within estuarine food webs. A significant amount of new information has also been accumulated on the human use and abuse of these habitats, particularly the effects of pollution. Although the world's seas are vast and may appear capable of receiving unlimited quantities of human effluent, such waste is often first discharged into the confined waters of estuaries. In practice, marine pollution is often essentially estuarine pollution. To reflect the huge impact of humans on estuaries, and to consider how we may either modify, remove or enrich the estuarine ecosystem, three completely new chapters have been prepared in this edition. These consider anthropogenic change (including pollution) in estuaries, the diverse uses and abuses of the estuarine habitat by man, and the methods used to study human induced changes in estuaries. Finally, this text examines the ways in which estuarine management can monitor, control or prevent the pollution and destruction of this fragile ecosystem.

Available in PDF, EPUB and Kindle. Book excerpt: The book contains papers on the biology of aquatic oligochaetes and some related groups. They cover a wide range of topics including phylogeny, taxonomy, geographic distribution, freshwater and marine ecology, population dynamics, histology and ultrastructure, physiology and behaviour. The wide scope is in line with recent trends in annelid research with less emphasis on pollution studies and faunistics and a renewed interest in experimental biology using new techniques.

Download or read book Trace Metals in the Westerschelde Estuary A Case Study of a Polluted Partially Anoxic Estuary written by W. Baeyens and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceans and lakes are characterized by large residence times and can thus be considered as being in an equilibrium or quasi-equilibrium state. In contrast, estuaries, which constitute the interface between the fresh water and marine ecosystems, are biogeochemically and physically very dynamic. Strong gradients in physical and chemical variables such as temperature, pH, salinity, dissolved oxygen, nutrients, amount and composition of particulates result from the mixing of fresh water and saline end members. These gradients provoke increased biogeochemical processes, generally resulting in a geochemical filter (the area of high turbidity, showing enhanced adsorption-desorption processes) and a biological filter (the area of high plankton activity showing, besides a high uptake of nutrients, a high accumulation of trace metals). Both filters disturb the conservative mixing pattern of the trace metals in an estuary. In addition, four aspects make the Scheldt estuary very unusual and different from other estuaries: the Scheldt is a tide-governed estuary which means larger residence times; the upper estuary receives large inputs of biodegradable organic matter which leads to oxygen depletion in winter and to anoxic conditions in summer; inputs of toxic pollutants occur in the upper estuary by the industrial park of Antwerp; the anoxic zone, the zone of pollutant input and the zone of the turbidity maximum coincide geographically. The Scheldt estuary is thus an ideal field laboratory for the study of biogeochemical processes which do not occur elsewhere, or only partially, to a very low extent or in a specific compartment, i.e. the sediments. More specifically, redox processes involving trace metals, the formation of non-labile metal complexes, and the methylation of mercury occur as a result of anoxic conditions and the high load of organic matter. Several models describing in detail the transport, the sedimentation and the speciation of the trace metals in this well-mixed estuary (all major estuaries in EC countries adjacent to the North Sea or the Atlantic Ocean are well-mixed) are presented in this book. A comparison of the metal concentrations over a 15-year period shows a net reduction of the pollution level.
Download or read book Fisheries and Aquaculture Volume V written by Patrick Safran and published by EOLSS Publications. This book was released on 2009-10-27 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries and Aquaculture theme is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Fisheries are a major life support system and the main purpose of this theme on Fisheries and Aquaculture is to provide baseline information and latest knowledge at the dawn of this century to facilitate vital fisheries recovery before their irreparable collapse. This Theme on Fisheries and Aquaculture is divided into five topics. It starts with discussions on major issues and challenges in “Harvesting the Seas”, with emphasis on the role and importance of the fisheries sector and its environment, and introduces trends and perspectives in marine fisheries, including allocation of use rights, subsidies, and port management. The next two topics present an in-depth and detailed knowledge on fish and other aquatic living resources that are commercially exploited and/or farmed. The third topic on Inland Fisheries presents salmonid fish, eels, shad, whitefish and smelt, carp, perch, pike and bass, tilapia, frog, and crustaceans. The fourth topic presents a comprehensive review of trends and perspectives in Aquaculture: Principles and Prospects. The fifth topic on Economics of Fisheries and Aquaculture reviews the latest views and concepts useful to apprehend the fisheries management regime, including a comparative static economic theory and a dynamic theory of fishery, spatial bioeconomic dynamics and role of international law in the management of marine fisheries, rights-based and community fisheries management, aquaculture economics, and game theory and fisheries. These five volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.
