Abstract

Individual physiological features of the Skeletonema costatum vegetation under low light intensity and low temperature are described; these peculiarities allow the species to prevail in the Black Sea phytoplankton in winter and early spring. This marine diatom is characterized by high growth efficiency under light-limiting conditions (0.13 day−1·(µE·m−2·s−1)−1) which indicates an increase in the specific growth rate of the alga with a rise in light intensity by 1 µE·m−2·s−1. Moreover, the species is characterized by low values of the light intensity saturating the growth – 12 µE·m−2·s−1 at +5 °C and 18 µE·m−2·s−1 at +10 °C. At +5…+10 °C, S. costatum growth rate is about 2 times higher than that of other representatives of the Black Sea phytoplankton in the winter–spring period. This diatom shows increased sensitivity to high light intensity: at +10 °C, photoinhibition of microalgae growth is observed under light intensity above 120 µE·m−2·s−1.
