Notes

In 1969 and 1970 investigations were made in the Konigshafen in order to find out in which way the occurrence of ciliates in the periphyton is affected by contamination of marine areas by municipal sewage. The periphyton was gained on plastic petri dishes which were fixed at rods by means of elastic clamps. Among the ciliates most attention was directed to the sessile Peritricha, first because they formed the major part of the periphyton, and second because they indicate changes in the environmental conditions for a longer time than vagile ciliates do. The ecological power of the peritrich ciliates has been investigated. An attempt was made to classify places of different intensity of pollution by difference in the diversity of the ciliates.
