The hair cortisol concentration (HCC) is assumed to be a retrospective marker of integrated
cortisol secretion and stress over longer periods of time. Its quantification is increasingly …

The polar bear (Ursus maritimus) is among the Arctic species exposed to the highest
concentrations of long-range transported bioaccumulative contaminants, such as …

Quantitating glucocorticoids (GCs) in hairs is a popular method for assessing chronic stress
in studies of humans and animals alike. The cause-and-effect relationship between stress …

Stress hormones, released into circulation as a consequence of disturbance, are classically
assayed from blood samples but may also be detected in a variety of matrices. Blubber and …

Hair analysis is emerging as a popular tool to examine stress and reproduction hormone
levels in wild mammals. The reliability of this approach, however, depends on an …

Stress levels of individuals are documented using glucocorticoid concentrations (including
cortisol) in blood, saliva, urine or faeces, which provide information about stress hormones …

Bioaccumulation of trace element contaminants with endocrine disruptive (ED) potential has
been noted in European brown bears, though evidence of their effects is lacking …

Monitoring glucocorticoids in faeces and hair is increasingly used in ecological studies and
provides a powerful and minimally intrusive mean to identify physiological challenges faced …

Abstract Analysis of cortisol in hair has become a widespread tool for assessment of
hypothalamic-pituitary-adrenal (HPA) axis activity because of its ease of collection and its …

Parasites can cause severe host morbidity and threaten survival. As parasites are generally
aggregated within certain host demographics, they are likely to affect a small proportion of …
