Soil algae and cyanobacteria of Moscow State University educational-scientific station «Satino»

The species composition of soil algae and cyanobacteria in landscapes with different types of land use was studied for the first time on the territory of the Lomonosov Moscow state University educational and scientific station (Kaluga region). 125 species and intraspecific taxa of algae and 35 species of cyanobacteria were found. The specificity of algal-cyanobacterial communities in soils under different types of forest, in clearings of different ages and on arable land was revealed. In a field experiment, the effect of hydrocarbon fuel contamination (gasoline, kerosene, and diesel fuel) on the algal-cyanobacterial communities of sod-podzolic soils was studied. It is shown that with the same primary load of pollutants, their toxicity to algae and cyanobacteria and the rate of recovery of algal-cyanobacterial communities depends on the type of land use of the territory, and with the same type of land use – on the water regime of soils. In the same soil, the specific of the pollutant also affects the recovery of algal-cyanobacterial communities. Data on the composition of algae and cyanobacteria successfully complement information about the biological activity of soils obtained by other methods.
