“…Additional studies in grizzly bears (Macbeth et al 2010), humans (Webb et al 2010), caribou and reindeer (Ashley et al 2011) support these findings. On the other hand, Lafferty et al (2015) determined variations in HCC between sexes in black bears, with female HCC ranging from 0.6 to 10.7 pg/ml compared to male HCC which ranged from 0.5 to 35.1 pg/ml.…”

Cortisol, which is produced in the adrenal glands, is an endogenous glucocorticoid hormone that delivers its hormonal message to cells by acting on glucocorticoid receptors. It is one of the main stress hormones responsible for stress responses in animals and humans, and its overproduction is characteristic of certain diseases. While acute stress disorder can be evaluated by means of measuring the cortisol concentration in blood and urine, chronic stress disorder can be detected by monitoring the cortisol concentration in fur or hair. Hair collection is simple, inexpensive and non-invasive, and can be performed easily and rapidly; thus, it appears to be a suitable method for determining the level of stress in dogs from shelters, abused dogs or dogs involved in different types of animal interactions. Since it is a relatively new method, monitoring cortisol in hair or fur requires further research in order to definitively prove its efficacy, and possibly to determine reference range values for different breeds of dogs.

“…Recently, keratin glucocorticoid concentrations have been investigated as a biomarker of chronic stress or persistent elevation in glucocorticoid concentrations in a variety of mammals, including Rhesus Macaques (Davenport et al, 2006;Dettmer et al, 2009), Crab eating Macaques (Herod et al, 2011), Common Marmosets (Clara et al, 2008), Vervet Monkeys Laudenslager et al, 2011), Domestic Dogs (Accorsi et al, 2008;Bennett and Hayssen, 2010), Domestic Cats (Accorsi et al, 2008;Finkler and Terkel, 2010), Eastern Chipmunks (Martin and Reale, 2008), Rock Hyrax (Koren et al, 2002), Caribou and Reindeer (Ashley et al, 2011), Grizzly Bears (Macbeth et al, 2010) and Polar Bears (Bechshoft et al, 2011), as well as birds (Bortolotti et al, 2008(Bortolotti et al, , 2009Harms et al, 2010).…”

“…Because female glucocorticoid responses to ACTH are consistently robust in both spring and autumn, we suggest that the observed sex difference primarily reflects suppressed male responsiveness during the spring. Sex differences in the sensitivity of the HPA axis, particularly during the breeding season, have been reported previously (Ashley et al, 2011;Cartledge and Jones, 2007;Keenan et al, 2009;van Lier et al, 2003). For example, in male sheep (Ovis aries), ACTH elicits a smaller glucocorticoid response during the breeding season versus the non-breeding season, yet female sheep respond to ACTH equally in the two seasons (van Lier et al, 2003).…”

As in many vertebrates, hormonal responses to stress vary seasonally in red-sided garter snakes (Thamnophis sirtalis parietalis). For example, males generally exhibit reduced glucocorticoid responses to a standard stressor during the spring mating season. We asked whether variation in adrenal sensitivity to adrenocorticotropic hormone (ACTH) explains why glucocorticoid responses to capture stress vary with sex, season and body condition in red-sided garter snakes. We measured glucocorticoids at 0, 1 and 4 h after injection with ACTH (0.1 IU g −1 body mass) or vehicle in males and females during the spring mating season and autumn prehibernation period. Because elevated glucocorticoids can influence sex steroids, we also examined androgen and estradiol responses to ACTH. ACTH treatment increased glucocorticoids in both sexes and seasons. Spring-collected males had a smaller integrated glucocorticoid response to ACTH than autumn-collected males. The integrated glucocorticoid response to ACTH differed with sex during the spring, with males having a smaller glucocorticoid response than females. Although integrated glucocorticoid responses to ACTH did not vary with body condition, we observed an interaction among season, sex and body condition. In males, ACTH treatment did not alter androgen levels in either season, but androgen levels decreased during the sampling period. Similar to previous studies, plasma estradiol was low or undetectable during the spring and autumn, and therefore any effect of ACTH treatment on estradiol could not be determined. These data provide support for a mechanism that partly explains how the hypothalamus-pituitaryadrenal (HPA) axis integrates information about season, sex and body condition: namely, variation in adrenal responsiveness to ACTH.
