Net aboveground primary production and soil properties of floating and attached freshwater tidal marshes in the Río de la Plata Estuary, Argentina

In the lower delta of the Paraná River, at the head of the Río de la Plata estuary (Argentina), we compared net aboveground primary production (NAPP) and soil properties of the dominant macrophyte Scirpus giganteus (Kunth) in a floating and an attached marsh community. Both marshes are tidally influ...
