Аннотация

Fires have a strong effect on soil microbiome, and the mechanisms of soil restoration after fires are currently not well understood. This study describes the characteristics of microbial communities in the Psamment Entisol soils of pine forests in the city of Togliatti after forest crown and surface fires. Geochemistry, soil respiration and microbial community structure via 16S rRNA gene sequencing were studied in different soil horizons. Both crown and surface fires resulted in the variations of microbial diversity and shifts in taxonomic composition. There is a tendency to an increase in the proportion of representatives from phyla Actinobacteria and Gemmatimonadetes for soil samples recovering after fires. An increase in the proportion of bacteria (Micrococcaceae, Blastocatellaceae) associated with the degradation of substances formed after combustion also has been shown. The research has shown that the crown fire has a smaller effect on the soil microbiome than the surface fire, the largest changes in the microbiome structure were found in the intermediate horizon. At the same time, differences in the structure of the soil microbiome between horizons are intensified after exposure to the soil of a surface fire.
