2.8 Data analysis
All pairwise comparisons were made using the Wilcoxon Rank-sum test of
the stats package (R Core
Team, 2020). Pearson correlation tests were added to plots with the
ggpupr package (Kassambara,
2020). Permutational multivariate analysis of variance (PERMANOVA)
tests was performed using the vegan package
({Jari Oksanen et al.,
2020), with a default 999 permutations.
