Do egg hormones have fitness consequences in wild birds? A systematic review and meta-analysis

Lucía Mentesana, Michaela Hau, Pietro Bruno D'Amelio, Nicolás M. Adreani, Alfredo Sánchez‐Tójar

This study reviews and analyzes 57 studies on egg hormones in wild birds, finding near-zero overall effects on maternal and offspring fitness but high heterogeneity.

Indirect genetic effects increase the heritable variation available to selection and are largest for behaviours: a meta-analysis

Francesca Santostefano, María Moirón, Alfredo Sánchez‐Tójar, David N. Fisher

This paper quantifies the impact of indirect genetic effects (IGEs) on heritable variation and evolutionary potential across 21 species, finding IGEs significantly increase heritability and are most prominent for behaviors.
