산불지에서 절지동물 포식자(거미목, 딱정벌레과, 반날개과와 개미과)의 군집구조, 종풍부도 및 풍부도에 대한 교란강도의 영향 (Influences of Disturbance Intensity on Community Structure, Species Richness and Abundance of Arthropod Predators (Araneae, Carabidae, Staphylinidae, and Formicidae) in Burned-pine Forest)

초록

The present study was carried out to evaluate arthropod predators (Araneae, Carabidae, Staphylinidae,and Formicidae) as bioindicator for forest disturbance. We selected 12 study sites according to disturbance intensities caused by fire intensity and recovery methods at Goseong, Gangneung, and Samcheok in Gangwondo.
Intensities of disturbance were characterized as follows: 0 (no fire), 1 (surface fire), 2 (crown fire), and 3(crown fire followed by reforestation). Arthropod predators were captured using pitfall trap. Species richness and abundance of Araneae, Carabidae, Staphylinidae, and Formicidae were not different along disturbance intensities.
However, species richness and abundance of grassland ants significantly increased in higher disturbance intensities. Abundance of grassland ants such as Formica japonica and Camponotus japonicas linearly decreased along litter depth. Furthermore, ant communities were clustered along disturbance intensities. In a one-time survey, ants may be most useful as bioindicator for forest disturbance among the four predator taxa, because ants actively forage for long seasons.
