Cyanobacteria and algae biodiversity of grounds and soils from south Kamchatka volcanoes

Abstract

54 species and intraspecific taxa from 5 phyla: Сyanobacteria – 3 species (5.5 %), Bacillariophy- ta – 22 species and intraspecific taxa (40.7 %), Ochrophyta – 1 species (1 %), Charophyta – 2 species (3.7 %) and Chlorophyta – 26 species (48.1 %) were revealed during the study on biodiversity of cyanobacteria and algae in samples of pyroclastic deposits and soils from Avachinsky, Vilyuchinsky, Koryaksky volcanoes and saddle between Avachinsky and Ko- ryaksky volcanoes. Representatives of amph.-forms dominated, which indicates an increased moistening of the volcanic substrate sampled on the slope and at the foot of the volcanoes.
