Study of Biodiversity of Algae and Cyanobacteria of Mutnovsky and Gorely Volcanoes Soils (Kamchatka Peninsula) Using a Polyphasic Approach

Volcanic activity has a significant influence on the development of terrestrial ecosystems, including Kamchatka Peninsula. We aimed to study algoflora Mutnovsky and Gorely volcanoes based use clonal cultures algae cyanobacteria, phenotypic molecular genetic analyses. A total 48 taxa were identified: 9 32 Chlorophyta (11 Chlorophyceae, 21 Trebouxiophyceae), 3 Ochrophyta, 4 Charophyta. In soils volcano, 30 found, in 24 observed. studied area, small coccoid or mucilage-producing algae, which belong cosmopolitan species, identified, representatives genera Bracteacoccus, Chlorococcum, Coccomyxa, Coelastrella, Klebsormidium, Neocystis, Vischeria. Certain detected for first time region, Bracteacoccus bullatus, Chlorococcum hypnosporum, lobatum, Coccomyxa subellipsoidea, Klebsormidium nitens, Leptosira obovata, Lobosphaera incisa, Parietochloris pseudoalveolaris, Stenomitos tremulus, Vischeria magna. Our analysis algal communities at different altitudes reveals expansion species richness with increasing distance from tops volcanoes. The obtained data allowed us estimate real biodiversity cyanobacteria Kamchatkan volcanic soils, as well ecologies these microorganisms.
