An analysis of CO2 emissions and soil microbiological activity has been performed in larch stands of different ages that developed on cryogenic soils and represent different stages of post-fire succession. An abrupt increase in the soil emissions of CO2 (by more than 2 times) in young stands (15–30 years old), as well as a decrease of soil-respiration rate(More)
The phospholipid fatty acid (PLFA) composition of microorganisms in podzolic soils of pine forests was studied in Central Siberia. The live microbial biomass in the 1-m mineral soil layer was found to gradually decrease with depth. Although the biomass decreased by half in the lower horizons, its content remained sufficiently high (12–14 nmol FAs/g soil).(More)
The paper focuses on investigating the densities of different ecological trophic groups of soil microorganisms, cellulose decomposition rates, and respiration of cryogenic forest soils in the north of Central Siberia and those of the southern taiga subzone, including those affected by surface wildfires. Psychrotolerant bacteria and micromycetes were found(More)
The dynamics of litter stock, microbial biomass, and composition and structure of microbial communities, were studied in the course of soil organic matter transformation during vegetation season. The dynamics of litter stock in coniferous and deciduous forests proved to correlate with the biomass and total abundance of microorganisms, particularly, with the(More)
