    • Figure 1. 

      Geographic distribution of the 10 sampling sites containing 296 sampling individuals. Sampling sites are described in detail in Supplementary Table S1.

    • Figure 2. 

      Distribution of betaNTI and betaNRI values.

      Table 1. 

      GLMMMCMC analysis on effects of plant phylogeney, geographical distance and environmental variables on the phylogenetic turnover of AMF communities with sampling site as a random factor. Bayesian postmean estimates and 95% credible intervals are shown. Geographical distance was the only factor significantly explaining phylogenetic turnover of AMF communities, as the 95% credible interval did not overlap with 0 and p < 0.05.
