Testate Amoebae Assemblages (Rhizopoda and Testacea) in the Peat Deposits of the Floodplain Terrace Swamp (the South of Forested Zone of Western Siberia)

Abstract

Testate amoebae assemblages were investigated in the peat deposits of the floodplain terrace swamp located in the southern taiga subzone of Western Siberia. It was revealed that tests of amoebae were well preserved in the minerotrophic peat. Variations in the structure of assemblages show that these bioindicators are sensitive to changes in the environment. The dynamics of the water table depth in the swamp within an 8500-year period was determined according to the analysis of testate amoebae. It reflects the fluctuations of climate humidity during the Holocene.
