Diversity and distribution of naked amoebae in water bodies of Sumy region (Ukraine)

Taxonomy of naked amoebae and specifi cs of their distribution
in water bodies of Sumy Region are presented. Our research identifi ed 12 species of naked amoebae of
11 morphotypes. We established their ecological groups relative to abiotic aquatic factors: euryoxidic,
stenooxidic, stenobiotic and those that survive in a wide range of organic matter content. According to
the species composition, swamp and riparian species complexes of naked amoebae were identifi ed. It was
found that species complexes of amoeba are infl uenced by such factors as temperature, concentration of
dissolved oxygen and organic compounds.
