图 8 不同养殖密度下斑节对虾肠道菌群在属水平的 LEfSe 分析
(a) 在属水平 (top 10) 的进化分支图。由内至外辐射的圆圈代表了由门至属的分类级别;在不同分类级别上的每一个小圆圈代表该水平下的
一个分类,小圆圈直径大小与相对丰度大小呈正比;黄色代表无显著性差异,其他差异菌属按其所在丰度最高的分组着色。(b) LDA 值分
布柱状图 (LDA 阈值 4.0)。左侧纵坐标为组间具有显著差异的菌属,横坐标为各菌属的 LDA 分析对数得分值,LDA 值越大表明该菌属差
异越显著。
Fig. 8 LEfSe analysis of intestinal microbiota of P. monodon at the genus level at different stocking densities
(a) evolutionary branching diagram at the genus level (top 10). Circles from inside to outside represent the taxonomic levels from phylum to genus. Each
small circle at different taxonomic levels represents a classification at that level, and the size of the circle diameter is proportional to the relative abund-
ance size; yellow represents no significant difference, and other different genera are colored according to the group with the highest abundance; (b) histo-
gram of the distribution of the LDA values (LDA threshold of 4.0). The left vertical coordinate is the genera with significant differences between groups,
and the horizontal coordinate is the logarithmic score of the LDA analysis for each genus; the larger the LDA value indicates the more significant differ-
ences between the modified genera.
