Table 4 The taxonomic classification of core OTUs (> 90% of all samples) based on RDP classification (v.10). The results of repeated measures ANOVA of the relative abundance of each OTU is also included. F statistics are included with degrees of freedom (Fdf, dfDen) where dfDen is the denominator df based on Kenward-Roger first order approximations with Kacker-Harville correction. * p < 0.05, ** p < 0.01, *** p < 0.001. Where significant, partial η2 effect sizes are presented parenthetically
