Avian eggs contain substantial amounts of maternal hormones and so provide an excellent
model to study hormone-mediated maternal effects. We review this new and rapidly evolving …

Selenium (Se) is shown to be an essential element for poultry nutrition and a great deal of
information has been accumulated for the last 20 years indicating that dietary form of Se is a …

Destruction of habitat is the major cause for loss of biodiversity including variation in life
history and habitat ecology. Each species and population adapts to its environment …

Metals can cause oxidative stress by increasing the formation of reactive oxygen species
(ROS), which render antioxidants incapable of defence against growing amounts of free …

Secondary sexual traits (SST) are usually thought to have evolved as honest signals of
individual quality during mate choice. Honesty of SST is guaranteed by the cost of …

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

Supplementary food given to birds can have contemporary effects by reducing the risk of
starvation, increasing survival and altering movements and reproductive performance. There …

We tested the hypothesis that mother birds counterbalance the negative effects of hatching
asynchrony for later–hatched chicks by increasing the yolk androgen concentrations in …
