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.
