The community of oribatid mites of the styrian-carinthian outlying mountains was investigated with regard to their diversity. Altogether, 80 soil samples from two different microhabitats (Loiseleuria procumbens and ?alpine meadows?) out of three several mountain regions (Koralpe, Stubalpe and Saualpe) were collected, from which one area was sampled both in summer and autumn. In total 3.845 adult oribatid mites, out of 40 families with 20 taxa were found. In the aftermath of this master thesis, several species-area-relationship-diagramms from the different sites, which are showing the difference regarding the species richness from other such investigations, were built. The low abundance results from the little number of soil samples, due to the short time of investigation. But there is a distinct similarity to the spectrum of taxa from earlier investigations. 31 taxa are not claiming to have special ecological demands, whereas 9 found species are predominantly indigenous to subalpine, alpine and highly alpine regions. It wasn?t possible to show any seasonal distinction of the samples. Both Loiseleuria procumbens and alpine meadows offer oribatid mites different microhabitats. The cluster analysis shows a distinct affinity between the type of vegetation and the association of oribatid mites. Further, historical facts like the increase of the tree line in the Middle Ages and the current peak phenomenon which keeps the forest currently away from peaks and ridges, play a big role in the understanding with regard to the relationship between the community of oribatid mites and the type of vegetation.
