A new paper out of the Cherry and Mortazavi labs has been published  in Restoration Ecology. In it, Tatariw et al. compared rates of denitrification and dissimilatory nitrate reduction to ammonium (DNRA) between a natural and constructed tidal marsh. In both marshes, denitrification and DNRA rates were greatest in the upper 10 cm of marsh sediment and generally declined with increasing depth. They also found that rates were greater in the natural marsh than the constructed marsh, suggesting impartial recovery of ecosystem function after 32 years. 

In a new paper in Ecosyststems, Macy et al. compared carbon (C) and nitrogen (N) stocks between marsh-dominated areas and mangrove-dominated areas in a Louisiana coastal wetland. Results suggested that mangrove encroachment can increases C and N in aboveground biomass stocks, but that it may not lead to differences in belowground toot and soil stocks.
