    We compiled all published and unpublished isopod distribution data not older than 30 years from the geographical unit of Transdanubia, the western part of Hungary. As a result, records from 758 localities were evaluated according to geographical position (UTM grids), altitude and habitat characteristics (type of vegetation, general moisture conditions within the habitat) by uni- and multivariate statistics. Out of the 57 species known from Hungary, 48 were found in the surveyed region. Overall, species richness varied only slightly, but significantly decreased from natural (undisturbed) wet habitats to disturbed dry habitats. Species composition differed between degraded and natural habitats and, within natural habitats, between highland and lowland sites. Composition of the above-mentioned three habitat classes showed extensive overlap, but species occurrences were associated with species groups found in previous studies for the Hungarian fauna. These results indicate a relatively uniform richness pattern with high compositional turnover according to geographical regions and habitat characteristics. Naturalness (degree of degradation) plays a crucial role in shaping terrestrial isopod assemblages. Keywords – assemblage type, habitat classification, isopod richness, meta-analysis, spatial scales
