Syntaxonomy of cyanobacteria-algae coenoses of caves of Russia and some neighboring countries

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).
