Estuaries are home to unique plant and animal communities that have adapted to brackish watera mixture of fresh water draining from the land and salty seawater. Here's a direct link to pollution, 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 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. Estuarine Ecology, Second Edition, covers the physical and chemical aspects of estuaries, the biology and ecology of key organisms, the flow of organic matter through estuaries, and human interactions, such as the environmental impact of fisheries on estuaries and the effects of global climate change on these important ecosystems. Estuary definition, that part of the mouth or lower course of a river in which the river's current meets the sea's tide. •estuaries are important, highly productive habitats at the sea-land interface •estuarine populations and communities are structured both by strong abiotic influences (e.g., salinity gradients) and biotic interactions (e.g., competition, predation, facilitation) •a variety of human actions have caused a large fraction of estuaries to be destroyed (e.g., infilling) or damaged (e.g., pollution) 1. An estuary is a partially enclosed body of water, and its surrounding coastal habitats, where salt water from the ocean typically mixes with fresh water from rivers or streams. Transcript. To reflect this large impact of mankind on estuaries, and to consider how mankind may either destroy or enrich the estuarine ecosystem, chapters consider pollution in estuaries, and the diverse uses and abuses of the estuarine habitat by man, as well as the methods used to study human-induced changes in estuaries, and the ways in which estuarine management can either monitor, control, or prevent pollution or destruction of the estuarine ecosystem. Usually ecology is defined as the study of the relation of organisms or groups of organisms to each other and to their environment. Because the rivers forming estuaries deposit eroded materials and estuaries can host a … quotations ▼ (geology) Formed in an estuary by alluvial deposition. • Ecology was first described as a separate disc ipline in 1886 by the German Biologist Ernst Haeck el. 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 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. For example, along the Great Lakes, river water with very different chemical and physical characteristics mixes with lake water in coastal wetlands that are affected by tides and storms just like estuaries along the oceanic coasts.

However, there are also several types of entirely freshwater ecosystems that have many similar characteristics to the traditional brackish estuaries. Many coastal features designated by other names are in fact estuaries (for instance, Chesapeake Bay). Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea. The federal guidelines offer the following guidance for definition of “coastal and estuarine areas” as: “Those areas within a coastal state that are part of the state’s coastal zone, as designated in the state’s federally approved coastal management program under the CZMA or within the state’s coastal watershed boundaries as described in NOAA’s Coastal Zone Boundary Review (October 1992). Estuarine Ecology, Second Edition, covers the physical and chemical aspects of estuaries, the biology and ecology of key organisms, the flow of organic matter through estuaries, and human interactions, such as the environmental impact of fisheries on estuaries and the effects of global climate change on these important ecosystems.

An estuary is thus defined by salinity rather than geography. Hydromorphology is a major driver of estuarine ecosystem functioning in that it can lead to both changed salinity conditions and/or the physical removal of organisms.
