Summary of statistical findings.

1Post-metamorphic infection prevalence was analyzed using a binomial GLM with the density and species treatments as predictors.2Proportion of animals in each mesocosm surviving to metamorphosis was analyzed using a binomial GLM with Bd treatment and density and species treatments as predictors.3Larval period was analyzed using a mixed effects model with Bd treatment and density and species treatments as predictors with individuals nested by mesocosm.4Post-metamorphic infection severity was analyzed using a mixed effects model with density and species treatments, mass at metamorphosis and larval period as predictors with individuals nested by mesocosm.
