Table 1 Mean effect size estimates and 95% credible intervals of the posterior distribution of parameters that influenced the presence of extra-pair paternity in black coucal clutches (effects in bold indicate statistically meaningful effects)

From: Certainty of paternity in two coucal species with divergent sex roles: the devil takes the hindmost

  1. The last column [P(β) > 0] gives the posterior probability of the hypothesis that the effect is greater than zero. For both models (a) and (b) the random effect was female ID. Model a: marginal R2 = 0.280, conditional R2 = 0.509; Model b: marginal R2 = 0.268, conditional R2 = 0.692
