SINOPSIS

Seasonal dynamics of species composition, species richness (S), abundance (N), biomass (B) of periphyton diatoms were studied using Shannon (H), Pielou (e) and Barger-Parker (DBP) indices. The experimental design included a monthly exposition of glass slides made from samples of Bacillariophyta in the Karantinnaya Bay of Sevastopol from December 2010 to January 2012; temperature in the seawater ranged from 7.5 to 22.5 °C. In total, 55 taxa (3 classes, 14 orders, 24 families, 49 genera) of Bacillariophyta were found; 11 species were dominant, 5 of them prevailed in abundance and 9 in biomass. The averages derived for the periphyton diatom community varied as follows: S − from 7 to 25, N − from 57·103 to 1229·103 cell·cm−2, B − from 0.007 to 0.353 mg·cm−2, H − from 1.4 to 3.3, and e − from 0.36 to 0.73, DBP − from 17 to 71.
