The past 30 years of immunological research have revealed much about the proximate
mechanisms of maternal antibody transmission and utilization, but have not adequately …

Aposematic theory has historically predicted that predators should select for warning signals
to converge on a single form, as a result of frequency‐dependent learning. However …

Physiological Adaptations for Breeding in Birds is the most current and comprehensive
account of research on avian reproduction. It develops two unique themes: the consideration …

Eggs of vertebrates contain steroid hormones of maternal origin that may influence offspring
performance. Recently, it has been shown that glucocorticoids, which are the main …

Life-history theory predicts that individuals should adjust their reproductive effort according
to the expected fitness returns on investment. Because sexually selected male traits should …

The yolk of bird eggs contains maternal carotenoids that may act as antioxidants thus
influencing offspring performance and survival. However, to our knowledge, this hypothesis …

In egg-laying animals, mothers can influence the development of their offspring via the suite
of biochemicals they incorporate into the nourishing yolk (eg lipids, hormones). However …

Predation risk is known to influence behaviour and development, especially in breeding
animals. Mothers may be selected to transfer information about the intensity of such risk to …

The emergence of safe and functional eggs for consumer acceptance has gained focus. The
production of carotenoid-enriched eggs has received attention due to its multifunctional …

The exploration of the effects of urbanization on bird demography has attracted much
attention, and several studies found lower reproductive success in towns, which suggested …
