The study was carried out in the Kivach Strict Nature Reserve situated middle taiga of Karelia. Albic Podzols formed over fluvioglacial sandy deposits different vegetation microgroups (lichen-, cowberry-, bilberry-, true moss-dominated) within a cowberry-type pine stand were surveyed. organic and mineral horizons these soils examined for structural functional setup microbial community. key groups microorganisms effecting nitrogen carbon cycling fluctuations bacterial numbers determined under microgroups. composition cellulolytic component community identified, its variation among demonstrated. It found that main contributor to soil respiration biogeocoenosis is top horizon, while activity part inhibited. Variations some ecophysiological parameters microbiota, such as basal respiration, biomass (Cmic) (Nmic) others, depend on moisture content forest floor thickness. data obtained through integrated studies can be used environmental monitoring.
