Stress responses play a key role in allowing animals to cope with change and challenge in
the face of both environmental certainty and uncertainty. Measurement of glucocorticoid …

Many aspects of the social environment affect hypothalamic‐pituitary‐adrenal (HPA) axis
function and increase circulating glucocorticoid concentrations. In this review, we examine …

Ecological and medical researchers are investing great effort to determine the role of M
aternally‐D erived S tress (MDS) as an inducer of phenotypic plasticity in offspring. Many …

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 …

Biomedical researchers have long appreciated that maternal stressors can induce
preparative and adaptive programming in offspring via exposure to maternal Glucocorticoids …

corticosteroids as biomarkers of stress in animals. Can. J. Anim. Sci. 92: 227–259. The …

The impact of global warming on poultry production has gained significant attention over the
years. However, our current knowledge and understanding of the mechanisms through …

The question of why maternal stress influences offspring phenotype is of significant interest
to evolutionary physiologists. Although embryonic exposure to maternally derived …

A growing body of evidence from across taxa suggests that exposure to elevated levels of
glucocorticoids during early development can have long-term effects upon physiological and …
