Fig. 2: Frequency histograms based on species data of the two mesoregions

small mammal assemblages was inhomogeneous, so there were significant differences in the frequency values of each species between the two mesoregions.

In the mesoregional spatial scale the statistical evaluation of small mammal abundances based on local detailed data (relating to breeding pairs) showed significant difference for 8 species (Table 2). The relative abundance of the four featured shrew species in two mesoregions showed that significant difference can be observed in the case of the common shrew and the Lesser white-toothed shrew (Crocidura suaveolens). As for the other two shrews, we have not received significant difference due to the overlap of confidence intervals (Fig. 3.). Clear difference can be seen in the case of root vole, on the diagram showing the abundance distribution of the low-frequency vole species, because it occurs only in the Fertő-Hanság area. Despite the fact that the field vole {Microtus agrestis) has similar habitat preference to that of the root vole, it occurred with lower relative proportion in the Győr basin than in the Drava floodplain, regarding pellets. Moreover, the European water vole (Arvicola amphibius) showed significant difference with high frequency in the Drava floodplain (Fig. 4). In terms of the relative abundance of mice species, only the striped-field mouse showed significant result (Fig. 5).
