Fig. 6From: Microbiome of vineyard soils is shaped by geography and managementa PCoA of the Bray-Curtis distance matrix for bacteria. The samples separated by location, site, and type. While samples from permanent grassland soils only rarely cluster with samples from different locations, vineyard samples from different locations in some cases are closely related (e.g., PT12-Ala, PT17-Mori, and PT13-S.Felice, and PT15-Ala, PT16-Besagno). b PCoA and of the Bray-Curtis distance matrix for fungi. While P1 and P2 samples from the same site form well defined, closely related groups, V samples still group together, but forming clusters that are usually clearly distinct from the corresponding P1 and P2 samples.
