Starea actuală a algelor planctonice din grupa Chlorophyta în lacul de acumulare Dubăsari [Articol]

Abstract

The article presents the results of the investigations on diversity and quantitative parameters of planktonic algae from Chlorophyta group during 2020-2024 in Dubasari Reservoir. There were presented by 29 species and varieties which are belongs to four orders: Volvoca- les-4, Chlorellales-3 Sphaeropleales -21, Desmidiales-1. It was established that the decrease in the diversity of algae from this group compared to previous years. The highest diversity of green algae was attested in the middle and lower sectors of the reservoir. In the formation of the number of species, green algae constituted about 60%, being more diverse in the summer period, and in the formation of biomass about 35%. According to the quantitative parameters of phytoplankton, green algae did not participate intensively in the formation of the population and biomass, except for the summer period of 2024.
