The size variability of some Black Sea diatom species
The heterogeneity of cell size spectrum of the culture Ditylum brightwellii, Thalassiosira parva, which were cultivated at the same conditions and Skeletonema costatum, Chaetoceros affinis, which were adapted to the different light conditions was determined. The coefficient of variation of D. brightwellii and Th. parva was 26 and 22 % percent, respectively. The heterogeneity of cell sizes of cultures adapted to different light conditions was varied from 20 to 30% percent, on average. It was established, that light intensity lead to grow in sizes of some diatom species, but the coefficient of variation at high light is smaller.
