title: Динамика физиологически активных клеток пико- и нанофитопланктона в прибрежных водах Черного моря
abstract: The dynamics of the abundance and viability index (VI) of picoand nanophytoplankton in the coastal waters of Black Sea near Sevastopol were investigated by regular monthly monitoring using flow cytometry and fluorescein diacetate vital dye (FDA), as a marker of intracellular enzyme activity. Directed seasonal changes in the fraction of physiologically active cells in the study groups of algae in coastal waters was not identified. It is noted that, in the warm season and during vegetative growth
