Cyanobacteria And Algae

Since the mid-twentieth century, the floristic classification principles are used in the systematization of cyanobacterial-algal coenoses (CAC) (Margalef, 1949; Bukhtiyarova et al., 1996; Khaibullina, 2000; Dell’Uomo, 2010; Golub et al., 2014). The types of cyanobacteria and algae communities of the caves have been identified (Roldan and Hernandez-Marine, 2009), but the floristic classification was not applied. Some attempts to classify of CAC caves using the Braun-Blanquet approach have been made, but the identified types were non-ranking, and the amount of initial data for their description was relatively small (Abdullin, 2009).

The Vertical Distribution

AbstractThe research was carried out in a mesotrophic and dimictic lake during winters with ice cover. In the last forty years, the development of phytoplankton was analyzed in five extreme winter seasons. The studies of phytoplankton characteristics in the water column took into account values of biomass, concentration of chlorophyll-a and species composition, including dominant species. Differences in the vertical distribution of flagellate and non-flagellate species belonging to cyanobacteria and algae were analyzed in the gradient of light and thermal conditions. The phytoplankton biomass was low and vertically differentiated, with the lowest values at the deeper part of the water column. Flagellate species from the group of Cryptophyceae, Chrysophyceae and Dinophyceae were most abundant. Species biodiversity was low but every winter the dominant species represented different taxonomic groups. In some periods, larger non-motile phytoplankton species from green or blue-green algae dominated. The research proved that the development of phytoplankton under the ice cover was limited mainly by light and, to a lesser extent, by temperature.
