| Abstract |
Laboratory research on the tubificids Psammoryctides barbatus and Spirosperma ferox was done. Embryonic development time, growth, time required to attain the first cocoon laying and egg production were estimated at different temperatures and population densities. The results allow us to demonstrate some intrinsic density regulation mechanisms in the profundal tubificid communities and substantiate the hypothesis that the succession from oligotrophic to eutrophic species in the profundal of lakes undergoing eutrophication is mainly based on their biotic characteristics. |
