TABLE 1.

Permutational ANOVA pairwise tests of beta diversity comparisons between the four life stages of the trematode parasite Coitocaecum parvum and potential external sources (their respective hosts, their surface microbiota, and the environment) with raw p-values and p-values corrected for multiple testing (BH-FDR, Benjamini and Hochberg correction).
