We investigated the spatial distribution of ground beetle species from the edge of secondary forests in Hwaseong-si, Gyeonggi-do. Nine secondary forests were selected, and 81 pitfall traps for collecting ground beetles were placed along forest interior―forest edge―forest exterior gradients during 14 June to 9 November, 2011. A total of 32 species belonging to 13 genera of 8 subfamilies were identified from 3710 collected ground beetles. Ten dominant species were selected for analysis. Five species such as Chlaenius micans (ANOVA, with Tukey's test, F2, 78=3.11, P=0.0502), Chlaenius ocreatus (F2, 78=2.76, P=0.0692), Dolichus halensis halensis (F2, 78=9.80, P=0.0002), Harpalus eous (F2, 78=2.73, P=0.0712), and Harpalus tridens (F2, 78=6.74, P=0.0020) were abundant at forest exterior. Three species such as Synuchus cycloderus (F2, 78=7.91, P=0.0007), Synuchus nitidus (F2, 78=9.72, P=0.0002), and Synuchus sp.1 (F2, 78=4.50, P=0.0142) were abundant at forest edge and forest interior. Coptolabrus smaragdinus branickii (F2, 78=3.24, P=0.0444) was abundant at forest edge and exterior. Finally, Chlaenius naeviger (F2, 78=1.39, P=0.2542) showed a wide distribution in this study. This study showed a significant edge effect on dominant ground beetles. Many environmental variables and prey items may be important factors for the spatial pattern of ground beetles. Because forest edges are generally important for many predaceous arthropods including ground beetles, the conservation and management of forest edges are important for maintaining biodiversity and ecosystem functions.
