99), with predominance of unicellular flagellates (MBFG V), represented mainly by Volvox aureus Ehrenberg and the significant occurrence of filamentous species (MBFG III), such as Komvophoron minutum (Skuja) Anagnostidis et Komarek, in addition to colonial species (MBFG VII) represented by Chlorophyceae Coelosphaerium kuetzingianum Nageli and Snowella lacustris (Chodat) Komarek (F).
An increase in phytoplankton community diversity occurs during the SHIP, where the elevated biomass of potentially toxic cyanobacteria (MBFG III) is replaced by non-toxic species, represented primarily by Volvox aureus (MBFG V), Aulacoseira granulata (MBFG VI) and Coelosphaerium Kuetzingianum (MBFG VII).
