The present paper studies ecological and taxonomic characteristics and structure of cyanobacterial-algal cenoses (CAC) of ordinary black soil used for growing legumes and cereals as phytoameliorants in Trans-Ural Republic of Bashkortostan. The study is based on classical algology methods. CAC analysis of soils used for growing phytoameliorants allowed identifying 134 cyanoprocaryote and algae taxa belonging to 70 genera, 36 families, 15 orders and 9 classes of five groups, including Chlorophyta, Cyanoprokaryota, Xanthophyta, Bacillariophyta, and Euglenophyta. With higher air temperatures and lack of moisture, the amount of euglenophytes drops completely, whereas the amount of yellow-green algae and diatoms declines. The analysis revealed negative correlation between CAC biodiversity and medium air temperature (r = - 0.99). With higher air temperatures, the amount of amp-forms drops and the range of CAC ecobiomorphs is less diverse. When comparing CAC ecobioforms, we revealed a change in soil composition typical for succession in case the soil is used for growing legumes and cereal grasses. The head end of the spectrum is dominated by CF-forms, and the number of hydrofilious and sciophiolous X-forms increases. The P-form algae, oftern related to the areas of disturbed land, are displaced. Ch-form ubiquists remain their leading position in the spectrum. The soil used for growing perennial legumes had 18 species of nitrogen-fixing cyanobacteria, the soil used for cereals had 13 species correspondingly. The total number of species revealed in soil used for growing legumes is almost 2 times more than the one revealed in soil used for cereals. Apparently, a small protective cover layer of legumes provides more shade for algae displaying the features of R-strategists and explerents and able to occupy the available space quickly.
