| Description | The oligochaete fauna was studied as a part of the research project of running water quality assessment based on prediction of macrozoobenthos community composition. Studied material was sampled at 57 unpolluted or moderately polluted streams in the Morava and Odra River basins (Czech Republic) in 1997 and 1998. The program TWINSPAN divided studied streams into five main groups with indicator oligochaete species. Canonical Correspondence analysis (CCA) was used to reveal the relationships among sampling sites. Principal Component Analysis (PCA) was used to characterize the major gradients of environmental variables. Evaluation of small streams based on aquatic Oligochaeta is possible; it provides better information about moderately polluted streams then about unpolluted ones. |
