This study was carried out at the LTER site (37.44 N and 127.08 E) in the Gwangneung forest, mid-western South Korea. Ants were surveyed in 2003 to 2005. The survey was carried out using pitfall traps one time per year in July to August in 2003 and 2004, and May to June in 2005 (Table 1). The traps had been set in the field for 11 or 14 days. The temperature for the sampling periods ranged from 13.4°C to 35.6°C with average of 23.8°C (24.1°C in 2003, 26.8°C in 2004, and 20.5°C in 2005) (Korea Meteorological Administration [2013]). Precipitation during the sampling period was 200 mm in 2003, 8 mm in 2004, and 32 mm in 2005. The LTER site (1 ha) was divided into 100 plots (10 m?×?10 m), using plastic pipes. Three pitfall traps were set along a transect of 2-m intervals, in the center of each plot. A total of 300 traps were set up each year, but 300, 267, and 283 traps were returned for analysis in 2003, 2004, and 2005, respectively. The unreturned traps were usually disturbed by boars. The pitfall traps were plastic cups (diameter 95 mm, depth 68 mm) and were one third filled with polyethylene glycol, a nonattracting and nonevaporating preservative (Bestelmeyer et al. [2000]). The ant specimens were identified using taxonomic keys (Imai [2006]; JAID [2010]; Terayama and Kuboda [2009]). The ants were identified to the level of species.Citation(s)
