Relative influence on soil microbial richness and dependency plot for the first five most important predictor variables in a boosted regression tree analysis. Each dependency plot represents the marginal effect of a predictor variable on soil microbial richness. Marginal effects were constrained in the model to be monotonic. (PR, plant richness; AN, soil available nitrogen).
