- In this research, the effect of the relationship between physical environment of islands and species diversity of South Korean insular Coleoptera was calculated, using South Korean natural environment survey data. Island size was directly proportional to species diversity. However, it was also inversely proportional in big inhabited islands. It is because the islands can support larger human population and undergo severe and continuous human disturbance. Island distance was not correlated with species diversity. However, island distance was directly proportional to the number of macropterous species. It suggests that macropterous species have advantage over brachypterous species in terms of reaching far islands and colonizing on their own in case of less outside disturbance. To test the difference of distribution of Coleoptera with different wing length, four islands around Boryeong city in Chungcheongnamdo province were surveyed. 755 samples were collected. Identification result showed the tendency that dominance index was inversely proportional to island distance and the rate of macropterous species. It may be originated from the characteristic of macropterous species such as slow colonization and fewer individuals in restricted area. Therefore, the difference of dispersal ability with wing length may affect species composition of islands. This research can be used as base data when predicting species composition and species diversity of uninvestigated islands.
