Abstract
The protozoans attached to the submerged roots of reed Phragmites australis in some small waters in Holland were studied during one year Reed was chosen because it is a very common natural substrate for epiphytically living animals Marked changes in species abundance and overall population density are reported Most important quantitatively were the ciliates especially peritrichs on which emphasis is laid Vorticella campanula Ehrenberg 1831 is found to be the dominant species in spring and summer other vorticellas being also very numerous Suctorian populations seem to change strongly within weeks without apparent reason Small attached flagellates were also common No stalked Heliozoa or mediumsized flagellates were found The generalisation of the results and comparisons with the literature are discussed
