Abstract

Ground-dwelling insect communities respond sensitively to environmental changes and serve as important biological indicators for understanding forest ecosystem changes. This study aimed to investigate how the diversity and functional traits of ground-dwelling insect communities change during the long-term ecological succession process in the afforested area of Gwangneung Forest. The survey was conducted in 2019, 2021, and 2023 using pitfall traps, and we analyzed community diversity and four functional traits of collected insects: food niche breadth, habitat type, size, and feeding type. A total of 1,442 individuals belonging to 6 orders, 27 families, and 94 species were collected. The results showed that abundance, Simpson index, Shannon diversity index, and evenness all increased significantly over the years. The dominant species varied annually: Synuchus arcuaticollis in 2019, Aphaenogaster japonica in 2021, and Adrisa magna in 2023. Regarding functional trait changes, food niche breadth and feeding type showed distinct variability, while size and habitat type exhibited gradual changes. Insect community structure showed distinct differences among years, and these changes were significantly correlated with soil exposure, woody debris, and understory vegetation coverage. This study confirmed that not only the structure but also the function of ground-dwelling insect communities have changed, and these changes are closely related to environmental factors. These results provide useful baseline data for monitoring ecological succession in forest restoration processes and establishing biodiversity conservation strategies.
