  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 males. 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. When 0 (zero) is not included in the credible intervals there is an effect of this parameter on the dependent variable (shown in bold). In the case of a significant interaction, the estimated difference of the interaction term is added to the difference of the main effect from the intercept
