When stimuli from the environment are perceived to be a threat or potential threat then
animals initiate stress responses, with activation of the hypothalamo–pituitary–adrenal axis …

According to recent empirical studies, reproductive senescence, the decline in reproductive
success with increasing age, seems to be nearly ubiquitous in the wild. However, a clear …

In this perspective paper, we emphasize the importance that integrative mechanisms, and
especially the GC (glucocorticoid) stress response, can play in the ability of vertebrates to …

In vertebrates, stressors such as starvation or predator attacks stimulate the rapid elevation
of circulating glucocorticoid hormones, triggering physiological and behavioral responses …

In this paper, we review the relationships that link avian parental behavior, stress (acute or
chronic) and energetic constraints to the secretion of prolactin, the 'parental hormone' …

There is increasing evidence that individuals in many species avoid areas exposed to
chronic anthropogenic noise, but the impact of noise on those who remain in these habitats …

How does an animal age in natural conditions? Given the multifaceted nature of
senescence, identifying the effects of age on physiology and behavior remains challenging …

Life‐history theory predicts a trade‐off between costs of current reproduction and future
survival of individuals. Studies of short‐lived animals in general support this prediction …

Seabirds often have high loads of contaminants. These contaminants have endocrine
disrupting properties but their relationships with some endocrine mechanisms are still poorly …

Summary 1 An emergency life‐history stage is expressed in breeding vertebrates when the
immediate survival is threatened by poor energetic conditions (ie allostatic overload). This …
