  1. Full parameters for model predicting introduction status within mammals traded live by the US, after iteratively removing variables with the highest VIFs until none were >5 (neonatal body mass, N = 312, H2 = 0.54 [0.25, 0.79]). Posterior mean = mean β coefficient from posterior distributions, l-95% CI and u-95% CI = lower and upper 95% credible intervals from posterior distributions respectively, % crossing zero = percentage of estimates in the posterior distribution that overlap with zero in the direction opposite to the majority of the distribution, VIF variance inflation factors.
