Anthropogenic Destabilization of the Soil-Biotic Communities State’ in the Geosystems on the South of Eastern Siberia

A successful study of the anthropogenic impact on terrestrial biogeocenoses, and especially on their biotic component – zoocenoses, is ineffective without observations of the soil fauna. The paper presents a comparative analysis of the structure and diversity of zoocenoses of natural and anthropogenic disturbed soils prevailing in the region, identifies the ecological features of soil invertebrate communities and the limitations of biota functions in the transformed environment, and considers the patterns of transformation of the community structure in the landscape-zonal range under the influence of natural conditions and anthropogenic factors. Landscape-ecological analysis of the taxonomic diversity and structure of the community of soil invertebrates in geosystems was carried out at the local (biogeocenology), topological (facies) and regional levels. The negative impact of anthropogenic pressure on the number, biomass and biodiversity of mesopedobionts is considered. Data on various forms of anthropogenic impact on soil biota at the regional level are summarized. Possibilities of using integral soil-biotic indicators for environmental monitoring and forecasting in conditions of potentially dangerous anthropogenic impacts are shown.
