A total of 1,529 individuals representing 52 species were collected. Species distribution patterns were controlled mainly by sediment type and the presence or absence o

At least 80% of all worms inhabited leaf sheaths at the bases of . plants, and densities were low in sediment, root and surface debris samples. Oligochaete densities were dependent on the position within the marsh

In the two great lakes, Titicaca and Poopo, the chemical properties of the water play an important part in the composition of the benthic fauna.

Marco Konersmann,Michael Goedickent environmental factors in the Dnieper-Bug Estuary were salinity, discharge, water quality, trophic condition and sediment characteristics. In the Lower DnieperBug a correlation was found between abundance and number of oligochaete species and the concentration of ammonium nitrogen and mineral phos

The results suggest an exponential decrease in number of individuals (N) relative to depth (11,165 N m. at 21 m, 265 N m. at 1200 m). Most oligochaetes were found in the top 7 cm of sediment. The orange colour of the
