Tolerance of Naked Amoebas (Protista) to the Abiotic Factors

The tolerance ranges of most distributed naked amoeba species are estimated for the first time on the territory of Ukrainian Polessje. On this base the ecological groups of naked amoebas were determined: eurythermal, stenothermal thermophilic, euryoxidic, stenooxidic, those marked in the wide range of permanganate oxidability values and in the narrow one.
