Epigeic spider communities of four bogs: Benes, Borsaros, Luci and Mohos including some of the surrounding forested habitats were investigated in Transylvania (Romania). All these peat bogs are protected natural sites as part of Natura 2000 ecological network. Fifteen sites in the four bogs were concurrently sampled by pitfall traps. The faunistical investigations revealed a rich and variable fauna of the studied bogs with 100 species from 19 families. Open bog habitats were the most species rich, wooded bog areas intermediate and forests proved to be the poorest. Forest habitats markedly differed in their dominant species and in assemblage composition from bog habitats, therefore significant faunal exchange cannot be expected between these habitats. The present study definitely showed the value of small bogs, which in fact showed greater species richness than the two larger area bogs. The effect of geographical distance and habitat interacted. If habitats were very different (forest vs. bog) then habitat difference was decisive, but among bog sites more proximal sites were also more similar in spider species composition. The bogs scattered about a relatively large geographical area and all contributed unique species to the larger scale 'bog species pool' of the region.
