Involvement of Planktonic Ciliata in the Process of Transformation of Suspended Organic Matter in Lake Kostomoyarvi (Kareliya)

RESUMO

Based on the experiments carried out, it is possible to conclude that the formation of fresh detritus in the closed cylinders was responsible for a sharp increase in the biomass of Ciliata. In this case, their ration increased from 10 to 50% of the total concentration of suspended organic matter, whereas organic matter decomposition increased from 5 to 70-80% of BOD1. Thus, in decomposing the detritus complex Ciliata are of considerable importance in the involvement of the newly formed sediments into the ecosystem.
