Notes.
Results of permutational multivariate analysis of variance analyses; | indicates significant differences between groups in pairwise comparisons; ns, non-significant; NA, pairwise comparison not applicable due to only two groups.
Degrees of freedom for each test are shown as subscripts for each respective Pseudo-F value.
