A) Redundancy analysis (RDA) performed on the parasite community (Hellinger-transformed presence-absence data). Individual coordinates on the RDA constrained axis scaled to [-1;1] (circles) and sexes placed at the mean of the corresponding individuals (squares and names). Arrows show correlations of each parasite taxon with the RDA constrained axis (bold arrows for |r| > 0.5). P-values on the left show results of univariate Likelihood ratio tests. B) Same as A for abundance data (Hellinger-transformed data, univariate F tests).
