Androgens and estrogens are steroid hormones that regulate reproductive processes in
both males and females. Monitoring plasma levels of these steroids or their metabolites …

Vertebrate embryos are exposed to maternal hormones that can profoundly affect their later
phenotype. Although it is known that the embryo can metabolize these maternal hormones …

Several studies show effects of yolk androgens in avian eggs on the phenotype of the
offspring. Yolk hormone concentrations decline strongly within the first few days of …

Animals and plants routinely produce more offspring than they can afford to rear. Mothers
can favour certain young by conferring on them competitive advantages such as a leading …

Increases in yolk androgens within and among avian clutches have been correlated with
decreased incubation time, increased aggression within a nest, increased begging …

Inter‐and intra‐clutch variation in egg corticosterone (CORT), the major glucocorticoid in
birds, may provide insights into how maternal stress levels vary with the timing of breeding …

Maternally derived hormones are known to influence the growth and development of
offspring. The differential deposition of these maternally derived hormones into egg yolk is …

Stable isotope (SI) and fatty acid (FA) profiles were examined in early and late-laid eggs of
three marine bird species; Arctic Terns (Sterna paradisaea), Common Eiders (Somateria …
