图2 不同树种组成森林中土壤甲螨群落结构及生态指标差异。A: A样地与B样地甲螨群落的非度量多维标度排序(non-metric multi-dimensional scaling, NMDS)分析结果(Stress = 0.1457)。其中椭圆代表围绕A、B两个样地甲螨群落的标准偏差, 红色的十字(OTU)代表群落中的甲螨物种。B、C、D分别表示两样地甲螨多度、物种丰富度和Shannon多样性指数差异。其中方块表示数据分布, 横线表示中位数, 圆点表示极值。

Fig. 2 Community structure and ecological indices of soil oribatid mites in different tree composition forest. A, Non-metric multidimensional scaling (NMDS) analysis showing the community composition of site A and site B. Ellipses represent the standard deviation around the centroids of each sampling site, red crosses refer to the lepidopteran oribatid mite species in each community. B, C, D, The difference of oribatid mites diversity between site A and site B. Boxes and whiskers represent the data distribution about the median, filled circles represent extreme values.
