Microplastic pollution is currently perceived as an environmental hazard, and adverse
effects have been reported at various levels of biological organization. However, most …

When vertebrate physiological ecologists use the terms 'stress' or 'physiological stress', they
typically mean the level of hypothalamus–pituitary–adrenal (HPA-) axis activation …

Long-distance migratory birds are often considered extreme athletes, possessing a range of
traits that approach the physiological limits of vertebrate design. In addition, their movements …

Glucocorticoid hormones (CORT) are predicted to promote adaptation to variable
environments, yet little is known about the potential for CORT secretion patterns to respond …

Wading bird foraging success and habitat preference can be greatly affected by prey
availability, which encompasses both prey density and the vulnerability of prey to capture …

Seasonal and annual variation in food availability during the breeding season plays an
influential role in the population dynamics of many avian species. In highly dynamic …

Food shortage challenges the development of nestlings; yet, to cope with this stressor,
nestlings can induce stress responses to adjust metabolism or behaviour. Food shortage …

In nest-bound avian offspring, food shortages typically trigger a release of the stress
hormone corticosterone (CORT). Recent studies indicate that CORT is passively deposited …

Generalist species are core components of ecological networks and crucial for the
maintenance of biodiversity. Generalist species and networks are expected to be more …

Early‐life conditions can drive ageing patterns and life history strategies throughout the
