Organisms frequently encounter stressful ecological conditions. In vertebrates, a major
mechanism of physiological response to stress is mediated by the hypothalamic–pituitary …

Many studies have been aimed at understanding the maintenance of female infidelity in
socially monogamous birds. Because engaging in extrapair copulations (EPCs) is believed …

To optimize fitness, organisms may have to trade the number and quality of individual
offspring against their own condition and survival. Limiting micronutrients such as …

Extra-pair paternity is the result of copulation between a female and a male other than her
social partner. In socially monogamous birds, old males are most likely to sire extra-pair …

In many species, each female pairs with a single male for the purpose of rearing offspring,
but may also engage in extra-pair copulations. Despite the prevalence of such promiscuity …

In many socially monogamous species, females copulate with and produce offspring sired
by males other than their social mates, yet it remains controversial whether or how females …

Mothers can influence the phenotype of their offspring by adjusting the quality of their eggs
in relation to sex and reproductive value of the progeny. Maternal androgens in the eggs of …

In the majority of socially monogamous bird species, extra-pair paternity (EPP) has been
shown to be common, while its frequency varies considerably among as well as within …
