Summary of the RF models for each OTU that had a validation score higher than 0.1; the overall averages of variance explained R2 and validation score were 0.45 and 0.23, respectively (full data is available in Additional file 4). a Variance explained (%) by each category of the predictors in our conceptual model for each OTU. b Variable importance of each predictor that was averaged across all the models (the numbers are the mean values in %); the box plot (B1) summarizes the distributions of all the predictors according to the conceptual model categorization across the OTUs (Fig. 1)
