Macrophytic primary production and nutrient concentrations in a deltaic floodplain marsh of the Lower Paraná River

  title={Macrophytic primary production and nutrient concentrations in a deltaic floodplain marsh of the Lower Paran{\'a} River},
  author={Carlos Alberto Cruz Villar and Laura de Cabot and Carlos A. Bonetto},
Biomass changes across an annual cycle were followed at two sampling sites in the floodplain marsh of the Lower Paraná River: close to the river-shore and 800 m inside the floodplain marsh, both dominated by Scirpus californicus and Cyperus giganteus. Tidal influence determines a daily exchange of water between the river and the floodplain marsh. Estimated net primary production was higher in the river (2820 against 1770 g m−2). Contents of nitrogen and phosphorus in plant tissue decreased from… CONTINUE READING
