Maternal effects can adaptively modulate offspring developmental trajectories in variable but
predictable environments. Hormone synthesis is sensitive to environmental factors, and …

Climate change is forecasted to generate a range of evolutionary changes and plastic
responses. One important aspect of avian responses to climate change is how weather …

In many species, embryos are exposed to maternal hormones in utero, in the egg, or in the
seed. In birds, mothers deposit substantial testosterone into their eggs, which enhances …

Female birds may adjust their offspring phenotype to the specific requirements of the
environment by differential allocation of physiologically active substances into yolks, such as …

Hatching asynchrony is widespread in birds laying clutches containing multiple eggs, yet is
seemingly paradoxical as the age and size hierarchies result in asymmetric sibling …

In oviparous species like birds, eggs provide the direct environment in which embryos are
develo**. Mothers may adjust different egg components in different ways in reaction to …

Capsule Accessing extra food from waste dumps increases egg volume and hatching mass
in White Storks. Aim To test how White Storks vary their investment in egg size, especially in …

In birds, mothers can affect their offspring's phenotype and thereby survival via egg
composition. It is not well known to what extent and time‐scales environmental variation in …

Agri-environment schemes (AES) are increasingly being employed to mitigate biodiversity
loss in agricultural environments. The European Turtle Dove Streptopelia turtur is an …

We assessed whether the ratio of dietary n‐6/n‐3 polyunsaturated fatty acids (PUFA) during
egg formation engenders transgenerational maternal effects in domestic chicks. We …
