Experimentally measured values of competence and virulence for the 20 different host-parasite combinations used in the mixed model analysis. Column names ------------ host_spp: Four letter code for amphibian host species. PSRE = Pseudacris regilla BUBO = Anaxyrus boreas TATO = Taricha torosa RACA = Lithobates catesbeianus parasite_spp: Code for parasite species Alaria: Alaria sp. 2 Rib: Ribeiroia ondatrae Echino: Echinostoma trivolvis Glob: Cephalogonimus americanus virulence: Coefficient from firth-adjusted logistic regression. Gives the change in log-odds of a host dying with an addition of one parasite. sample_size_virulence: Number of data points used in the firth-adjusted logistic regression. competence: The average fraction of meta or mesocercariae that successfully infected a host 20 days post-exposure. sample_size_competence: The sample size from which average competence was calculated.
