Cönológiai hasonlósági mintázatok indikációs ereje genuszszint? taxonlisták és gyakorisági eloszlások alapján

Abstract

Abstract. Several methods and indicators can be used to evaluate the coenological state of a given habitat, the ones which can be created simply, quickly, standardizably and reliably can be of outstanding practical importance in environmental biology. One possible method is listing the genera which can be found in a given habitat in great abundance and have little number of species and various ecological characteristics. For this purpose one of the most appropriate groups is that of ground-dwelling oribatid mites. In our research the indication strength of genus-level taxon lists and the effects of the main patterngenerating factors creating similarity patterns were analysed with the help of data series on oribatid mites collected by us and originating from literature. Our aim was to develop a method with the help of which the difference expressed with distance functions between two oribatid mite genus lists originating from any sources can correspond to spatial and temporal scales. With the help of this base of comparison changes in disturbed or transformed habitats can be expressed by means of oribatid mite communities, with spatial and temporal distances.
