^a N = 253 / 113 /66 (samples/ individuals/ infected); R² _marginal = 0.224, R² _conditional = 0.224, σ² < 0.001

Predictions are based on the final, reduced models of the prevalences of the three common parasite morphotypes and morphotype richness after dropping the terms age*sex and body mass where they had non-significant (P > 0.1) effects (empty cells).
