This page intentionally left blank The World’s Largest Wetlands Ecology and Conservation During the past century, humans have destroyed approximately 50 percent of the world’s wetlands As wetlands shrink in area, their important functions decline too: there is reduced carbon storage, lower biological diversity, lower fish production, less available water during drought, higher flood levels in spring, and higher risk of water pollution The world’s largest wetlands have not been described, ranked, and compared previously For the first time, an international team of scholars shares its understanding of the status, ecological dynamics, functions, and conservation needs of the world’s largest wetlands L a u c h l a n H F r a s e r was recently appointed the Canada Research Chair in Community and Ecosystem Ecology at Thompson Rivers University He has published over 25 scholarly papers and is on the editorial boards of Applied Vegetation Science and the Ohio Journal of Science Dr Fraser’s research group examines the processes that organize plant communities and the functional consequences of different emergent patterns on ecosystem functions His laboratory focuses on ecosystems that are among those most affected by anthropogenic and natural disturbances, namely freshwater wetlands and temperate grasslands Pa u l A K e d d y holds the Edward G Schlieder Endowed Chair for Environmental Studies Over his career Dr Keddy has published more than a hundred scholarly papers on plant ecology and wetlands, as well as serving organizations including The National Science Foundation (NSF), The Natural Sciences and Engineering Research Council (NSERC), the World Wide Fund for Nature, and The Nature Conservancy He has been recognized by the Institute for Scientific Information as a Highly Cited Researcher in the field of Ecology and the Environment His current research examines the environmental factors that control wetlands, and how these factors can be manipulated to maintain and restore biological diversity The World’s Largest Wetlands Ecology and Conservation Edited by Lauchl an H Fraser and Paul A Keddy    Cambridge,
