  1. ANOVA, analysis of variance.
  2. Statistics describe linear random-intercept models of Shannon diversity and Chao1 richness in leaves and roots. ‘Obs’, total number of observations (log-transformed). All P values were corrected for multiple comparisons using the sequential Bonferroni correction. Significance was assessed using Type III ANOVA with F tests for fixed effects and likelihood ratio tests for random effects. Bold values indicate statistically significant results after correction for multiple comparisons, P<0.05.
