Fig. 2

The comparison of differences in the microbiomes of Acarus siro cultures that were not treated with pirimiphos-methyl (control). A shows the heatmap of standardized relative abundances of bacteria in mites from the four cultures. The lengths of triangles on the left side of the heatmap indicate the variability in the samples from the same culture. A similar level of variability and microbiome similarity is seen in the OTU clusters at the top (uncondensed intro triangles). Both clusters (samples and OTUs) were constructed using the unweighted pair group method with arithmetic mean (UPGMA) in Bray–Curtis distance. The red color in OTUs indicates high variability explained in SIMPER analyses. B is a triplot of a distance-based redundancy analysis (dbRDA) indicating the position of samples according to ax1 and ax 2. The samples from the same culture are organized as convex hulls, and the most important bacterial OTUs are shown. Ax1 and ax2 explained 53% and 8% of the variability in the model, respectively
