Abstract

Post-fire changes of the functional characteristics of soil microbial coenoses and the complexes of soil invertebrates in the middle-taiga pine forests of Central Siberia were studied. It was revealed that the fire events, independently of their intensity, during the first year cause a decrease in the number of diversity of soil invertebrates, and also have a negative effect on the structure and the functional activity of microbial complexes of sandy podzol. The post-fire recovery of the number and structure of the complexes of soil invertebrates and the functionаl activity of microbial coenoses of sandy podzol is determined both by the action of the pyrogenic factor and by the features of the dynаmics of hydrothermal and trophic conditions of soil in pine forests.
