Taxonomic and ecological composition of surface soil cyanoproсariotic-algal macroscopic expansions in the city of Ufa and its surroundings

The ecological and taxonomic characteristics as well as the structure of cyanoprocaryotic-algal macroscopic expansions on the territory of Ufa (industrial zone) and in Ufa region (village Yumatovo-control zone) have been studied. The study is based on classical algology methods. In macroscopic surface soil expansions on the territory of the industrial zone and in the control zone 75 specific and intraspecific taxons of cyanoprocaryotes and algae have been identified. The representatives of the group Cyanoprokaryota predominate. Heterocyte-free cyanoprocaryotes act as dominants most often. The presence of the representatives of Xanthophyta group in surface soil expansions in Yumatovo is noteworthy. The number of dominants in the expansions vary in the range of 1 to 4 for specific and intraspecific taxons in different combinations. The main part of cyanoprocaryotic-algal cenoses (CAC) in soil macroscopic expansions of the two zones compared are the species of the families Phormidium, Leptolyngbya, Nostoc...
