Table 4 Effects of within-canopy and within-leaf positions on the composition of phyllosphere microbial communities of European beech (Fagus sylvatica), tested using permutational multivariate analyses of variance (PERMANOVA). Compositional dissimilarities among samples were estimated using a binary version of the Jaccard index. The effects of within-canopy position (C), within-leaf position (LBV: blade edge, blade central part or main nerve), and their interaction were tested using sample Set#2 (Fig. 1C). The effects of within-canopy position (C), within-leaf position (LST: surface vs. tissue), and their interaction were tested using sample Set#3 (Fig. 1C). Permutations were constrained by sampling date (D) and tree identity (T)
