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

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)

Parameter	Mean estimate	2.5%	97.5%	P(β) > 0
(a) All clutches (n = 169)
Intercept	−0.602	−0.994	− 0.222
Lay date	−0.146	−0.500	0.209	0.216
Clutch size	0.302	−0.101	0.718	0.927
Proportion of young genotyped	0.573	0.189	0.968	0.998
*Clutch size Proportion of young genotyped**	0.481	0.039	0.918	0.983
(b) Completely genotyped clutches (n = 62)
Intercept	0.343	−0.400	1. 060
Lay date	0.211	−0.419	0.851	0.749
Clutch size	1.285	0.252	2.305	0.992

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
