ECOLOGICAL AND BIOLOGICAL CHARACTERISTICS FORMICROALGAE OF SAND SUBSTRATES OF THE ODESA BAY (THE BLACK SEA)

Abstract
The studies revealed 74 taxa of microalgae that live on sandy substrate in the Odesa Bay. The most common representatives of phytopsammon are Navicula salinarum Grunow, Diploneis chersonensis (Grunow) Cleve, Cylindrotheca closterium (Ehrenb.) Reimann et J. C. Lewin, Plagiotropis lepidoptera (W. Greg.) Kuntze, Attheya decora T. West, Pleurosigma elongatum (W. Sm.) van Heurk, Entomoneis paludosa (W. Sm.) Reimer. The most species (39 %) that are presented move freely over the substrate. However 27 % of the species are attached to sand grains. With respect to the salinity there are three groups which are the most abundant: oligogalobes (40 %), mezogalobes (31 %) and poligalobes (29 %). Most microalgae are alkaliphilic and cosmopolitans. The presence of oligosaprobes and xenosaprobes testifies the ongoing processes of self-purification on the coast of the Odesa Bay.
