Distribution of Oligochaeta in some lakes and pools of Boliviand eastern sides of the Bolivian Royal Cordillera. Benthic fauna of the small lakes include several typical taxa known exclusively from South America. 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.

Aquatic Oligochaeta of the Dnieper-Bug Estuary systemnt 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 phosphorus in the water.

The centriolar remnant with an indistinct ninefold symmetry in cross section is located posterior to the mitochondria. The prominent central sheath extends from the mitochondria to the end of the flagellum, which has no end piece.

Individuals that show homozygotic bands of glucosephosphate-isomerase (GPI) 22 together with isocitratedehydrogenase (IDH) 35 were labeled Type A. Type B is characterized by GPI 23 together with IDH 11 and Type C is characterized by GPI 11 with either IDH 34 or IDH 33. Ini
