Table 1.

Results from mixed-effects models are shown for α- and β-diversity indices. Significance was determined using ANOVA. For each test, we report the relevant F statistic (F_4,19) and significance (p(>F)). Degrees of freedom were constant across all tests (numerator degrees of freedom: 4, denominator degrees of freedom: 19).
