Abstract

Species composition and algal community organisation were studied in 34 sample sites located along the main river courses of the Some? Basin. Relative abundance of species in the communities was performed and expressed as percentage. The frequency distribution pattern of the species has been described by employing the truncated normal curve model. Affinities at the level of algal communities have been tested by cluster analysis using the floristic similarity index of Sorensen. Species diversity, as well as relative information has also been computed according to Shannon's formula. Diatoms were found to be dominant in the river communities both as number of taxa and population density. They were used to evaluate the saprobic status of water in sampling sites. Floristic composition and structure of the investigated communities inhabiting the river sectors were found to differ according to the local conditions.
