图3 不同退化阶段亚高山草甸土壤原生生物群落差异的LEfSe分析。ND: 未退化草甸; LD: 轻度退化草甸; MD: 中度退化草甸; HD: 重度退化草甸。每个圆环为一个分类学层次内的所有分类群, 从内到外的圆环分别代表超群、门、纲、目和科; 圆环上的节点表示分类学层次上的一个分类单元, 每个节点的直径与丰度成正比; 不同退化程度草甸中相对丰度显著较高的分类单元(生物标志物)在进化分支图中进行了颜色编码。

Fig. 3 LEfSe analysis showing soil protist community differences in subalpine meadow at different degradation stages. ND, Nondegraded meadow; LD, Lightly degraded meadow; MD, Moderately degraded meadow; HD, Heavily degraded meadow. Each circular ring deposit all taxa within a taxonomic level, the circular ring from inside to outside represents supergroup, phylum, class, order and family, respectively. The node on the circular ring represents taxon, affiliating within the taxonomic level. The diameter of each node is proportional to the abundance of the group. Taxa that had significantly higher relative abundance in a certain treatment within each meadow degradation type were color-coded within the cladogram.
