  1. Data shown are estimates and 95% Bayesian credible intervals of natural log-transformed CORT concentrations. Estimates are relative to the intercept as reference level, which here is the mating stage of African females. The left column shows the post-capture and the right column stress-induced CORT, each with the corresponding Bayesian estimate and its’ credible intervals. Estimates of cofactors refer to differences from the intercept estimate, which here is the mating stage of African females. When 0 (zero) is not included in the credible intervals there is an effect of this parameter on the dependent variable (shown in bold)
