Fig. 1

Venn diagrams showing the number of OTUs that were unique to and shared among different communities. Rarefaction curves of the observed OTU numbers of all the samples from the six types of communities after rarefied. Percentage stacking diagrams show the community composition of bacteria and fungi at genus and species levels. The top 30 genera and species were selected for abundance analysis. Three quadrats were set for each population, with 18 quadrats in 6 populations. The abscissa is the proportion of species in the sample, and the ordinate is the plot. Different colored columns represent different species, and the length of the columns represents the proportion of the size of the species. The abbreviations of species are shown in Supplementary Table S4
