MORPHOLOGICAL VARIABILITY OF SPECIES OF THE GENUS ACHNANTHIDIUM (BACILLARIOPHYTA) RARE FOR THE FLORA OF RUSSIA
The study of phytoplankton in the Nizhny Tagil Reservoir using scanning electron microscopy made it possible to obtain the data on morphology of some representatives of the genus Ashnanthidium: A. catenatum, A. dolomiticum, A. eutrophilum, A. saprophilum. The ranges of variability of the main diagnostic features (length and width of the valve, number of striae and areolae in 10 µm) were found and new values were obtained for some of them; the first data on such an important ultrastructural feature as the number of areolae in 10 µm were obtained for the species A. catenatum, A. dolomiticum, and A. eutrophilum.
