Recently, many habitat corridors have been constructed in Korea, but the effect of corridor types, i.e. overpasses and underpasses, on arthropods was poorly examined. Therefore, we compared the effect of habitat corridor types in terms of abundance, species richness, and composition of carabid beetles. As a result, 3,737 ground beetles belonging to 60 species were collected by pitfall trapping across the northwestern forest–habitat corridor–southeastern forest transects in 2015. Abundance and species richness of total carabid beetles in underpasses were significantly lower than overpasses. And species composition of underpasses corridors was significantly different compared to other habitats, such as overpasses and forests. Although more samples are needed to understand the effect of corridor types, the current underpasses may be unfriendly structures to movement of ground dwelling arthropods as well as carabid beetles.
