| Sumario: | There are scarce studies concerning phytoplankton biodiversity in floodplain environment. This suggest the need of taxonomic studies for the conservation and recuperation of these ecosystems. Xanthophyceae was studied in relation to taxonomy and contribution to phytoplanktonic density and biomass. Samples were taken from limnetic and seaboard regions in 33 biotopes in the Upper Parana River floodplain, between February 2000 and February 2001. This group occurred in 61% of the biotopes and 20 species were registered. Gloeobotrys lunatus Ettl, Goniochloris spinosa Pascher, Istmochloron neustonica Zalocar and Pizarro and Pseudostaurastrum limneticum (Borge) Chodat were considered first citation for this system. The highest number of taxa was registered in the biotopes near Parana River, especially in the Osmar Lagoon. The contribution of Xanthophyceae to density and biomass was low throughout the studied period and the higher values occurred during high water period |
