From: Using soil bacterial communities to predict physico-chemical variables and soil quality
a Relative compositional differences (Bray-Curtis dissimilarity) between bacterial community composition at sites with different land uses. Vectors represent soil environmental variables which significantly correlated with the ordination (P < 0.05 based on 999 permutations); variables in black represent those with well-defined soil quality guidelines which were therefore used in subsequent modelling. Stress value for the ordination was 0.14. b The number of correct (n = 103) and incorrect (n = 18) predictions of land use type, based on a random forest classification of bacterial community data. Black borders indicate correct classifications
