Early growth interactions between a mangrove and an herbaceous salt marsh species are not affected by elevated CO2 or drought, Louisiana saltmarsh, 2015 In recent decades the encroachment of woody mangrove species into herbaceous marshes has been documented along the U.S. northern Gulf of Mexico coast. These species shifts have been attributed primarily to rising sea levels and warming winter temperatures, but the role of elevated atmospheric carbon dioxide (CO2) and water availability may become more prominent drivers of species interactions under future climate conditions. In this greenhouse study we examined the effects of CO2 concentration (ambient, elevated) and water regime (drought, saturated, flooded) on early growth of the mangrove species Avicennia germinans and Spartina alterniflora, a herbaceous grass.

Understanding the ecological influence of macroclimatic drivers is important because it provides a foundation for anticipating the effects of climate change. Tidal saline wetlands include mangrove forests, salt marshes, and salt flats, which occupy similar geomorphic settings but different climatic regimes. However, most global- or regional-scale analyses have treated these wetlands as independent systems. Here we used climate and literature-derived ecological data from all three systems, collected across targeted regional-scale macroclimatic gradients, to test hypotheses...

N; 76.61 deg. W). This site was created in 2007 following an engineering plan developed by Dr. Michael Burchell (NC-State University). This data collection was to support the development of a site-specific carbon budget. Data were collected from 2011 to 2013, or approximately 4-6 years post-creation. The data collection specifically funded by the U.S. Geological Survey includes plant carbon biomass, plant above ground biomass, plant below ground biomass, plant decomposition, and soil greenhouse gas fluxes, and these data are being made available. These data represent critical components of the carbon...
