Summary of linear mixed-effects models for diversity metrics on belowground biomass in the BioCON experiment. R2 are shown for observed versus predicted values. Comparisons are based on Akaike weights, with larger weights indicating greater relative strength of evidence for that predictor. Slopes are standardized and associated P-values are for significance of diversity metrics on belowground biomass.
