We have done the effect of different concentrations of oil on the testate amoebae community structure in soils of sub-taiga zone of Western Siberia. Oil concentrations were 10, 20, 50, 100 and 200 g/kg of soil. The greatest impact on the structure and number of communities had oil pollution concentration of200 g/kg. Testate amoebae genus Plagiopyxis, Centropyxis, Cyclopyxis the most sustainable, and testate amoebae genus Corytion, Trinema, Nebela, Hyalosphenia less resistant to oil pollution. Stability of three main genera (Plagiopyxis, Centropyxis, Cyclopyxis) caused by a structure of shell. There are four main stages in the development of adaptations communities testate amoebae: resistance, reduction in the numbers and species diversity of communities, the depressive stage of cist and extinction, restorative stage. Each of the stages of restructuring communities pay with the decrease of the factors capable to recover.
