| Summary: | The aquatic oligochaeta were studied in the Cri$uri Rivers between 1994-1998 in two research campaigns. In this paper wc compare the results of the two campaigns and we apreciate the evolution of the oligochaeta fauna from the Criijuri Rivers according to the environmental modifications. Wc observed that in the most river parts the number of the species decreased and sometimes their density increased. This fact is probably due to the higher organic pollution of the river portions in certain periods of time. |
