Moscow Microbiome of background and anthropogenically disturbed soils of the Franz Josef Land and Novaya Zemlya archipelagos, the Rybachy, Yamal, and Taimyr pe ni nsulas (Dikson settlement), as well as the Bol she zemelskaya tundra (near Vorkuta) was characterized. Data on structure of microbial biomass, number of cells of pro karyotes and fungi, emission of greenhouse gases from soil, number of ribosomal genes of microorganisms we re obtained. Judging by large number of cells of various groups of microorganisms, high emissions of greenhouse gases, and a significant level of functional nitrogen cycle genes, soil microbiome of studied soils has a high adaptive potential to extreme environmental conditions, which allows them to perform their functions even under conditions of anthropogenic interference.
