Net aboveground primary production and biomass dynamics of Schoenoplectus californicus (Cyperaceae) marshes growing under different hydrological conditions
We studied different functional attributes on two Schoenoplectus californicus (C. A. Mey) Sójak marshes that appear as very similar communities in terms of structure and dominant species, although they are settled on opposite ends along a fluvial-tidal gradient in the Lower Delta of the Paraná River...
