Abstract:
The ciliate fauna of a small, unpolluted stream, the Breitenbach in Hesse, Germany, was investigated during 1990-1992; 143 taxa were found: 113 taxa occurred in periphyton on artificial substrata and 69 taxa in the sediment; 39 taxa were common to both habitats. There was a high degree of similarity between several sampling sites along the stream. Those species which were constant representatives of the Breitenbach fauna were ubiquistic, there was no specialized ciliate fauna characteristic of the stream.
