Differences in soil environmental factors (soil hardness, cobble cover, and plant litter cover) according to the occurrence patterns of Eremias argus. The yellow bar represents the zone with a high frequency of E. argus (F zone, n = 78), and the mint-colored bar represents the zone where E. argus is rare (R zone, n = 60). Differences in a soil hardness b cobble cover, and c plant litter cover between these two zones were considered. Standard errors are shown as error bars, and signs above the bars indicate whether the values differ from two zones (* p < 0.05, *** p < 0.001).
