Values in brackets are 95% credible intervals. ‘Sex’ indicates difference in males relative to females; ‘Age’ is the effect in years; ’IR’ is an individual’s internal relatedness value; ‘Season’ is the effect of breeding season relative to non-breeding; and Age*IR is the interaction. Variance component estimates (for additive genetic variance VA and shared environment variance VS), heritability (h2) and the proportion of variance attributed to a shared environment effect (ICCS) are all presented on both latent and observed data-scale. Parameters estimates were converted to the observed data-scale using the QGglmm package (see Methods for details of models). N=324 individuals.
