Appeals to all wetland scientists, from ecologists to those involved in the design of constructed or treatment wetlandsServes as a teaching text for advanced undergraduate and graduate courses as well as professional reference About a fourth of the plants, half of the fish, two-thirds of the birds, and three-fourths of the amphibians categorized as threatened or endangered in the United States are associated with wetlands. These wetalnd areas can help control flooding, reduce wave action, slow down the flow of water, and improve water quality. Biogeochemistry of Wetlands is the first comprehensive book on biogeochemical cycling in these critical habitats. Taking an in-depth look at the chemical and biological cycling of nutrients, trace elements, and toxic organic compounds in wetland soils and water, the authors examine the most diverse and important ecosystems on Earth. They cover freshwater and coastal wetlands and their role in global climate change.
