Counts of <i>E. trivolvis</i> metacerariae versus tadpole mass (log scaled), for the six tadpole density and host diversity treatments.

<p>Dots are observed infection intensities in individual tadpoles, thick lines are the predicted (from NB GLMM model) infection intensity for an animal of a given mass in that treatment, and thin lines represent 95% Bayesian credible intervals. Larger animals were more likely to be infected, but the rate of increased infection with size depended on treatment. Note that per-capita ETa infection increased with <i>Rana</i> density (R16 vs. R24 vs. R48), but was not affected by the addition of alternative hosts (RHP vs. R16, RH & RP vs. R24).
