While the hypothalamo–pituitary–adrenocortical (HPA) response to stress appears to be
conserved in vertebrates, the manner in which it is activated and its actions vary. We …

The assumption that the acute response to stress is adaptive is pervasive in the literature,
but there is little direct evidence regarding potential positive fitness consequences of an …

The scientific study of networks-computer, social, and biological-has received an enormous
amount of interest in recent years. However, the network approach has been applied to the …

Plasma levels of corticosterone are often used as a measure of “stress” in wild animal
populations. However, we lack conclusive evidence that different stress levels reflect …

The mechanistic bases of natural and sexual selection on physiological and behavioral traits
were examined in male morphs of three colors of the side-blotched lizard, Uta stansburiana …

Many aspects of reproductive physiology are subject to regulation by social interactions.
These include changes in neural and physiological substrates of reproduction. How can …

There is considerable evidence that the increases in circulating corticosterone levels
following acute stress, such as sudden storms, can trigger facultative behavioral patterns …

The magnitude by which plasma cortisol levels increase following exposure to a stressor is a
heritable trait in rainbow trout. The relative growth in coculture of F1 lines selected for high …

Noninvasive administration of cortisol through the diet resulted in relatively rapid (< 1.5 h)
and highly reproducible increases in plasma cortisol in rainbow trout, comparable to …

Unstressed and stress-induced plasma corticosterone levels in Galápagos marine iguanas
(Amblyrhynchus cristatus) were compared in animals from a site heavily exposed to tourism …
