Abstract

It is shown that natural populations of diatom algae of the genus Navicula (N. cryptocephala, N. exilis, N. hanseatica, N. margalithii, N. menisculus, N. meniscus, N. radiosa, N. reinhardtii, N. rhynchocephala) manifest significant variability of the main morphological quantitative features: length and width of the valve, number of the striae and lineols in 10 μm, that should be considered during systematic, taxonomic, floristic, and hydrobiological studies.
