Closteriaceae, Desmidiaceae, floodplain lake, taxonomyAbstract
This study aimed to taxonomic survey of planktonic Zygnemaphyceae in a lake in upper Paraná River fl oodplain. In addition, this study evaluated the constancy of this group of algae between periods of high and low water for four years. Samplings were carried out in the limnetic region of the lake in March, June, September and December 2000 of 2010 and 2011 and in February and August of 2001. A total of 25 algal taxa were recorded, distributed among the families Closteriaceae and Desmidiaceae. The represented genera were Closterium Ralfs (5 spp.), Cosmarium Ralfs (6), Euastrum Ralfs (7), Micrasterias Ralfs (5) and Pleurotaenium Nägeli (2). Sporadic and rare species were recorded more often. Only Closterium incurvum Brébisson, C. lineatum Ehrenberg ex Ralfs, Cosmarium protractum (Nägeli) De Bary var. protractum, Euastrum abruptum Nordestedt var. abruptum and E. ansatum Ehrenberg species were considered common. There was no distribution pattern of taxa between hydrological periods.
