121 Does Nutrient Pollution Jeopardize Tidal Wetland Viability? A Controversy Revisited

Nutrient loading to coastal wetlands has increased significantly since preindustrial times. However, ecosystem responses to this global change driver are poorly understood, especially belowground. In addition to increasing aboveground productivity of tidal wetlands, nutrient addition may also 1) cause plant community shifts, 2) increase or decrease root productivity, and 3) alter organic matter decomposition. Several very recent studies have reported a link between the effects of eutrophication and the degeneration of wetland ecosystems, while others have suggested increased stability. Our symposium will revisit this developing controversy after a vibrant symposium four years ago.
