Stress Physiology and Behavior Problems
… our etiological understanding. Adversity and stress have been a focus in criminology research but few studies have incorporated stress physiology, the biological underpinning of how individuals deal with adversity. This dissertation comprised three papers testing the linkage of stress …

Stress Physiology of Phytophthora-canker Pathogens in Landscape Trees: impacts, mechanisms, and mitigation through biochar amendment
… water potential data suggested a slight moisture stress in the inoculated group compared to the control group, which may have contributed to the photosynthetic decline. Early reductions were probably not due to water shortage and are most likely caused by pathogen-derived signals, or hormonal …

Genetic analysis of p38 mitogen-activated protein kinase signaling in innate immunity and stress physiology of Caenorhabditis elegans
… interactions play an important role in the physiology and evolution of animals. Interactions with microbes can generally be considered beneficial or pathogenic to the host. The ability of an organism to mount an immune response to infection by pathogenic microbes is critical to its survival, …

Retranslocation and volatilization of shoot nitrogen during drought in perennial prairie grasses
… of shoot N may occur in response to water stress in these species, which would likely have important consequences for growth and survival during and after drought. Little is known about retranslocation of N or other nutrients in response to drought or other environmental stresses in plants, …

Extended Adolescence: The Ecology and Endocrinology of Facultative Paedomorphosis
… density, predator presence, hydroperiod, and stress hormones in regulating the expression of paedomorphosis. Results indicated the regulation of paedomorphosis through multiple ecological factors may be reducible to density-mediated effects, with a few notable exceptions. I also show that …

An integrative approach to testing density effects in a migratory songbird, the Prothonotary Warbler (Protonotaria citrea)
… of density on the reproduction, behavior, and physiology of a population of cavity-nesting songbirds, the Prothonotary Warbler (Protonotaria citrea), in southern Illinois, USA. From 2008-2011, I experimentally manipulated the availability of nest boxes by establishing two low-density and two …

From physiology to pixels: Resource allocation tradeoffs and noninvasive technologies for studying marine mammals
… how markers of energy balance and metabolism, stress physiology, and iron mobilization relate to reproductive history to reveal mechanisms governing maternal trade-offs between self-maintenance and reproduction. High-quality females that had consistently higher reproductive output, exhibited …

Early neighborhood disadvantage and risk for internalizing problems: underlying neurobiological mechanisms
… exposure with neural network topology and stress-related outcomes in emerging adulthood. Participants were typically developing 18- to 19-year-olds (N = 77) from socioeconomically diverse backgrounds. They reported their home address history and underwent resting-state functional magnetic …

Investigating the role of a JNK-like MAP kinase signaling in regulating dauer developmental arrest in Caenorhabditis elegans
Many metazoans have the ability to respond to stressful growth environments by arresting in a diapause state. The young larvae of nematode Caenorhabditis elegans undergo drastic anatomic and metabolic remodeling to enter a developmental diapause called dauer in response to crowding, diminished food …

Behavioral Heterogeneity and Disease Dynamics in House Finches (Haemorhous mexicanus)
… the relationships among host behavior and physiology, anthropogenic food sources, and disease transmission in a natural host-pathogen system. First, we examined the relationship between house finch (Haemorhous mexicanus) stress physiology, exploratory behaviors, and social behaviors in the …

Regulation of C. elegans behavior and physiology by the hypoxia-response pathway
… functions in immunity, oxidative and other stress responses, and behavior; how HIF targets drive these aspects of animal physiology is poorly understood. In this dissertation, I describe genetic analyses of the nematode C. elegans that have provided insight into the function of HIF targets …

Effects of Supplemental Hydration on Physiology and Behavior of Northern Pacific Rattlesnakes (Crotalus oreganus oreganus)
… nature. While it seems intuitive that drought is stressful to animals, studies examining drought are typically observational and fail to assess how the hydration state of these animals influences their physiology and behavior. We tested for an effect of hydration on several physiological and …

Validation and use of novel techniques to study the impacts of large-scale environmental changes on the health of wild waterfowl
… an increasing number and magnitude of stressors associated with the rapidly changing world. Repeated or prolonged stressors can trigger sustained elevations of glucocorticoids, resulting in detrimental effects on health and reproduction, with potential impacts on populations. This Ph.D. …

Autogenic regulation training (ART), sickness absence, personal problems, time and the emotional-physical stress of student nurses in general training : a report of a longitudinal field investigation
… in providing a method of coping with individual stress. Analyses were made between and within an ART group of student nurses and a comparison group who did not receive training in ART. Consideration was also given to individual differences of student nurses in each group.Particular attention was …

An Evaluation of Yellow Perch Perca flavescens Mortality in South Dakota
… population dynamics; and 3) evaluate the stress physiology and energetics of yellow perch in relation to mortality for two yellow perch populations that exhibit divergent population dynamics. Researchers have documented two distinct types of yellow perch populations in South Dakota glacial …
