Stress in a conservation context: a discussion of glucocorticoid actions and how levels change with conservation-relevant variables
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 …

The role of glucocorticoids in the vertebrate response to weather
Abstract Changes in the environment related to inclement weather can threaten survival and
reproductive success both through direct adverse exposure and indirectly by decreasing …

[PDF][PDF] Glucocorticoid-mediated phenotypes in vertebrates: multilevel variation and evolution
Fluctuations in abiotic and biotic conditions exist in almost all habitats (Dunlap, Loros, &
DeCoursey, 2004; Stevenson et al., 2015). Some fluctuations like the alternation between …

The relationship between fitness and baseline glucocorticoids in a passerine bird
Glucocorticoid (cort) hormones are increasingly applied in studies of free-ranging animals,
with elevated baseline cort levels generally assumed to indicate individuals or populations …

How foraging works: uncertainty magnifies food-seeking motivation
Food uncertainty has the effect of invigorating food-related responses. Psychologists have
noted that mammals and birds respond more to a conditioned stimulus that unreliably …

Understanding context dependence in glucocorticoid–fitness relationships: the role of the nature of the challenge, the intensity and frequency of stressors, and life …
It has been well-established that there is variation in the strength and direction of the
relationship between circulating glucocorticoids (GCs) and fitness. When studies …

Unpredictable food availability induces metabolic and hormonal changes independent of food intake in a sedentary songbird
Environments often vary with regard to their temporal resource availability, but little is
understood concerning how resource predictability impacts animals. The adaptive …

Food, stress, and reproduction: short-term fasting alters endocrine physiology and reproductive behavior in the zebra finch
SE Lynn, TB Stamplis, WT Barrington, N Weida… - Hormones and …, 2010 - Elsevier
Stress is thought to be a potent suppressor of reproduction. However, the vast majority of
studies focus on the relationship between chronic stress and reproductive suppression …

Hungry or angry? Experimental evidence for the effects of food availability on two measures of stress in develo** wild raptor nestlings
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 …

[HTML][HTML] Eye region surface temperature dynamics during acute stress relate to baseline glucocorticoids independently of environmental conditions
Reactions to acute stressors are critical for survival. Yet, the challenges of assessing
underlying physiological processes in the field limit our understanding of how variation in …
