- Аннотация: Testate amoebae are widely used in palaeoecological studies as indicators (proxies) of environmental conditions in mires and freshwater ecosystems. The goal of this work was to identify patterns in the dynamics of the species composition of testate amoeba assemblages during a “waterbody–mire” succession. This study was performed using multiproxy analysis of the deposits in Mochulya Bog, Kaluga oblast, European Russia. To explain changes in the species composition of testate amoebae, we used data on the plant macro-fossil composition, peat humification, and the loss on ignition, together with the results of radiocarbon dating and pollen analysis. The deposit was formed by the sediments of the waterbody, with rich fen and poor fen.The age at the base of the deposits was 4100 cal. yr. BP. Changes in the species composition of testate amoeba assemblages were largely determined by local vegetation, especially Sphagnum mosses, which significantly transform the environment. The ransformation of the waterbody into a rich fen may have most likely occurred as a result of climatic (allogeneic) factors: short-term drying and wildfires that might have led to the overgrowth of the shore. The transformation of the rich fen to a poor fen could have been related to the effects of both autogenic (accumulation of the deposits) and allogeneic factors (decrease in human activity in theadjacent area).
