Notes

This paper aims to describe the ecology and determine the distribution of Oligochaeta according to sediment type, depth and other environmental factors in 21 lakes of the National Park of the Lithuanian SSR. Diagrams are included showing the distribution of the lakes according to the index of density and biomass of Oligochaeta in the trophic structure of biocenosis of the zoobenthos. Light is thrown on the problem of sediment composition as a significant factor in the distribution and development of aquatic Oligochaeta.
