Community structure and distribution of ground beetles (Coleoptera: Carabidae) in Baekdudaegan Mountain, Gangwon-do, Korea

다국어 초록 (Multilingual Abstract)

Globally, c. 0.81.2 million species of insects exist, with Coleoptera making up about 40% of this total. Pitfall traps for collecting ground beetles were installed at 11 study plots in Baekdudaegan mountain of Gangwon-do. Individual trapped species were counted and analyzed at each study area. This study has been carried out to provide basic data for analyzing forest health and investigating the competitive distribution among biological species in the forest environment through a field investigation on the species composition, diversity, and dominance rate of Coleoptera. Carabidae were collected using pitfall traps at the study area in Backdudaegan Mountain of Gangwon-do, and the individual number of collected species was counted. Collected ground beetles in the study area comprised 837 individuals, 14 genus, and 32 species. In this study, 217, 303, 144, and 209 individuals were found in Jinburyung, Mt. Odaesan, Mt. Taebaeksan, and Mt. Dutasan area, respectively. The abundance of ground beetles was relatively high at higher altitudes than at lower altitudes and similarity differently showed in accordance with altitudes. Eucarabus sternbergi, Aulonocarabus seishinensis, and Synuchus spp. and Pterostichus spp. (Harpalidae) were widely distributed in our study area. The diversity index of species was the highest at the Mt. Odaesan study area.
