Eutrophication

Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. It is similar to red tides, depending on the degree of eutrophication. Similarities include subsequent negative environmental effects such as anoxia and severe reductions in water quality, fish, and other animal populations. This book gathers the latest research from around the globe in the study of eutrophication including such topics as the role of fish communities in the eutrophication of shallow lakes; nutrient cycling in salt marshes to reduce eutrophication; the influence of eutrophication on arsenic speciation in lake waters; and the cost, ecosystem benefits and policy implications of remedial measures to combat coastal eutrophication.
