Evaluation of fecal glucocorticoid metabolite assays for short-term stressors and validation for stress monitoring in African herbivores
During stressful periods, glucocorticoid production is increased. Glucocorticoid metabolites are found in blood, urine and feces. Our first goal was to determine if fecal glucocorticoid metabolite (FGM) measurements are a reliable means of detecting short-term ([greater than] 30 min) stressors in …

The foraging ecology of banded mongooses (Mungos mungo): Epidemiological and human-wildlife conflict implications
… the potential role of prolonged elevations of glucocorticoids in impairing cell-mediated immunity, which would play a significant role in determining susceptibility to a mycobacterium such as M. mungi, however, researchers have no data on the endocrinology of banded mongooses. Finally, …

Effect of selection for interspecific behavior on stress and conspecific behavior in tame and aggressive foxes
… and test a method for noninvasive measurement of fecal glucocorticoid metabolites (FGM) as a proxy for hypothalamic-pituitary-adrenal (HPA) axis activity in tame and aggressive foxes. Glucocorticoid measurement from fecal samples is a practice that has been validated in other canids, such as …

Development and evaluation of a terrestrial animal-borne video system for ecological research
… AVED attachment increases the stress levels (fecal glucocorticoid metabolites [FGMs]) of captive white-tailed deer (Odocoileus virginianus). Using a repeated measures analysis of variance, I found no difference in FGMs between control and treatment individuals during a 6 week trial that …

Non-invasive assessment of stress hormones, parasites, and diet, using scat of five felid species in Belize, Central America
… habitats on native felids by comparing fecal glucocorticoid metabolite (FGM) concentrations, endoparasite species richness (ESR), and diet using non-invasive scat sampling in a protected forest vs. surrounding non-protected areas in Belize. Field studies relying on non-invasive fecal …

The Relationship of Dominance, Reproductive State and Stress in a Non-Cooperative Breeder, The Domestic Horse (<em>Equus caballus</em>)
… I recorded the social interactions and measured fecal glucocorticoids in pastured, female horses that were either lactating or non-lactating. While fecal glucocorticoid level did not differ between reproductive state and rank, activity behavior demonstrated significant differences between …

FEMALE COMPETITION AND THE ROLE OF TESTOSTERONE IN A POLYGYNOUS SYSTEM
… role in competitive ability. Immunoreactive fecal testosterone metabolites (fT) were strongly positively correlated to both dominance rank and number of agonistic bouts initiated per hour, but only agonism was associated with fT when dominance and agonism were accounted for simultaneously. …

Are Highways Stressful for Pikas?: Analysis of Stress Hormones of the American Pika (<i>Ochotona princeps</i>) Living Adjacent to Interstate 90 in the Cascade Range of Washington State
… in the Cascade Range of Washington. I extracted fecal glucocorticoid metabolite (fGCM) concentrations from fresh fecal samples to determine chronic stress levels in pikas living adjacent to the highway compared with those living in similar rock embankment in a rails-to-trails state park, and in …

Social and Ecological Influences on Maternal and Infant Outcomes in Rwenzori Angolan Colobus Monkeys
… factors on (1) infant survival, (2) maternal glucocorticoid concentrations, and (3) infant independence in a population of Rwenzori Angolan colobus monkeys (Colobus angolensis ruwenzorii) in Uganda. These monkeys live in a multi-level society with three tiers of non-random association: the …

Integrative perspectives of wild and captive sifaka conservation
… relationships between captive sifaka fecal glucocorticoid metabolite levels and captive husbandry conditions. I found that age and contraceptive use, but not enclosure type, season, or sex, influenced glucocorticoid excretion (Chapter 3). These results highlight the importance of …

Health Surveillance of Thinhorn Sheep (Ovis dalli) Herds in British Columbia and Alaska
… in Alaska (P = 100% in 2019, and 73.9% in 2020). Fecal glucocorticoid metabolite concentrations determined from hunter-harvested and live-captured sheep increased annually. Serum and tissue copper levels in some herds were in the range considered deficient for domestic sheep. Other trace minerals, …

How the Outside Gets in: Linking Social and Physical Environments with Physiology and Body Size in Wild Baboons
… data on the Amboseli baboons for over 50 years, fecal hormone data for over 20 years, and blood samples collected via brief anaesthetizations for nearly 10 years. We complemented these remarkable datasets with cross-sectional data of female baboon body size.</p><p>In Chapter 1, we address two …
