Correspondence analysis of bacterial and fungal communities, constrained by vegetation zone.

Analysis is based on relative abundance of 354 bacterial OTUS and 273 fungal OTUs across six zone classifications. Markers indicate individual samples (three per zone type), and dispersion ellipses show the 99% standard deviation confidence interval for each zone. Environmental variables with significance p < 0.05, are shown as biplotted vectors (based on permutation tests; n = 1000). Unconstrained ordinations and scree plots are provided in S1 Fig and S2 Fig.
