In the region of the “Siebengebirge” near Bonn, six characteristic biotopes were studied with respect to the occurrence of fruiting body forming myxobacteria. 23 different species, belonging to the 8 known genera, were found. The number of species in the respective biotopes varied between 6 and 17, the average numbers of species per sampling area were between 2.1 and 10.0. 15 species were found on dung pellets of wild living herbivorous mammals. Deciduous forest soils contained 13 species in spring, 17 species in autumn. Rock covering contained 14, creek slopes 16, bark of living trees 9, and rotting wood 16 fruiting myxobacterial species. Myxococcus fulvus, Myxococcus coralloides and Archangium gephyra occurred in all biotops studied. The rare species were Melittangium boletus, Polyangium vitellinum, Stigmatella aurantiaca , and Chondromyces apiculatus. The composition of the myxobacterial flora depends on ecological factors (kind of dung pellets, rock, bark, and pH). The ecological influences upon the distribution are discussed.
