Seasonal development dynamics of microbocenoses and complexes of invertebrates on overburden heaps of the Borodinskoye brown-coal mine (KATEK)

We have investigated the seasonal-dynamics parameters of functioning of microbocenoses and invertebrate complexes on overburden heaps of different ages as well as the recultivation technology for of the Borodinskoye brown-coal mine. The 20-year-old overburden heap with typical natural reforestation and formation of a coarse-humus horizon was characterized by the largest balance of microbiological processes of organic matter destruction, and by high numbers and diversity of microarthropods. The youngest heaps are characterized by an unbalance between organic matter mineralization-immobilization processes and predominance of pioneer invertebrate groups in the community.
