Correlation between evenness and other variables We observed a marginally non-significant increase in RUE with increasing evenness at the regional scale (r = 0.47, p = 0.076) ( Fig. 6A ), but this correlation reversed when analyzing the treatment residuals for RUE and evenness instead (r = −0.447, p = 0.096, Fig. 6B ).
