Dendrogram and heatmap of bacterial distributions of the top 100 abundant OTUs present in the microbial community of the fifteen samples. The numbers indicate the actual reads number of the OTU. The heatmap plot depicted the relative abundance of each sample and the relative values for OTUs are indicated by colour intensity. Z: Tetrix japonica; ZS: Ruspolia lineosa; M: Erianthus versicolor; LG: Gryllotalpa orientalis; HLYHL: Teleogryllus emma.
