GLM procedures on egg provisioning parameters.

The results of the GLM procedures on egg provisioning parameters (dependent variables) are given for the entire clutch and for the intra-clutch ratio between A-egg and B-egg. Whether the females were paired with the same mate as during the previous breeding season or with a new mate is a fixed factor and male body mass, female body mass and A-egg laying date are covariates. Values of yolk androgen (andro.) concentrations (C°) and amounts were obtained from principal component analysis (PCA; see methods). n = 60 clutches. Significant P-values, P<0.05, are marked in bold.
