Why do we get the stress-related diseases we do? Why do some people have flare ups of
autoimmune disease, whereas others suffer from melancholic depression during a stressful …

As the number and diversity of animal species meriting conservation intervention increases,
improving the success of translocation efforts is vital and understanding the role of …

SYNOPSIS. Superimposed upon seasonal changes in morphology, physiology and
behavior, are facultative responses to unpredictable events known as labile (ie, short-lived) …

Over the past few decades, there has been a steep increase in the number of conservation-
related field studies that measure glucocorticoid hormones (corticosterone or cortisol) as a …

Stressors elicit a complex but variable suite of endocrine events. Comparative studies of the
stress response have focused primarily on the adrenocortical response to stress, in …

When an animal detects a stressor, it initiates a stress response. The physiological aspects
of this stress response are mediated through two endocrine systems. The catecholamine …

In a wide range of bird species, females have been shown to express active preferences for
males that sing more complex songs. Current sexual selection theory predicts that for this …

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

The study of physiological stress and its context in free-ranging animals provides a means
for understanding the challenges found in the natural habitat. Patterns of physiological …

Eggs of vertebrates contain steroid hormones of maternal origin that may influence offspring
performance. Recently, it has been shown that glucocorticoids, which are the main …
