Stress And Predation Impacts On North American Quail Translocations, Curt A. Vandenberg, Sarah A. Currier, Jeffrey G. Whitt, Kelly S. Reyna Sep 2022

Stress And Predation Impacts On North American Quail Translocations, Curt A. Vandenberg, Sarah A. Currier, Jeffrey G. Whitt, Kelly S. Reyna

National Quail Symposium Proceedings

Translocations have been used in attempts to bolster or restore native quail populations for >150 years, often with little success. However, with some northeastern United States quail populations undetectable or extirpated, and others across the United States on the extreme decline, translocation as a tool for quail population restoration is becoming increasingly popular. Two factors contributing to translocation failure are physiological stress and predation. Chronic stress associated with translocations can result in weight loss, reduced immune system function, suppressed reproduction, and an altered fight-or-flight response. These stress-induced responses increase vulnerability to predation, the primary cause of quail mortality. Here, we …


Cascading Effects Of Hunting Disturbance On Northern Bobwhite Behavior, Physiology, And Survival, Emily Prosser, Theron M. Terhune Ii, Kristen J. Navara, Geoff Beane, James A. Martin Sep 2022

Cascading Effects Of Hunting Disturbance On Northern Bobwhite Behavior, Physiology, And Survival, Emily Prosser, Theron M. Terhune Ii, Kristen J. Navara, Geoff Beane, James A. Martin

National Quail Symposium Proceedings

The northern bobwhite (Colinus virginianus; hereafter, bobwhite) is an important gamebird across the United States and has been in decline for several decades. As a commonly hunted prey species, the bobwhite provides an ideal study species to investigate the use of proactive and reactive antipredator behaviors in response to hunting pressure. We designed an experiment to understand how late-season hunting affects bobwhite demographics using fecal glucocorticoid (fGCM) concentrations, foraging and movement behaviors, survival, and breeding season metrics. Our results show that bobwhite responded to increased interactions with a shotgun through proactive responses. After one encounter with …


“Sometimes The People Giving The Care Get A Little Overlooked”: Athletic Trainers’ Personal Use Of Psychosocial Strategies And Interactions With Mental Performance Consultants, Alexander Bianco Aug 2022

“Sometimes The People Giving The Care Get A Little Overlooked”: Athletic Trainers’ Personal Use Of Psychosocial Strategies And Interactions With Mental Performance Consultants, Alexander Bianco

Doctoral Dissertations

In National Collegiate Athletic Association Division I (NCAA DI) athletic departments, athletic trainers (ATs) must navigate an array of stressors in the workplace, and are effectively performers themselves (Estock & Simon, 2018, Mazerolle et al., 2013). While ample research has been conducted on the stressors that ATs experience (see Oglesby et al., 2020) there has been limited work surrounding how ATs can best navigate this environment. Therefore, the purpose of the current investigation was to explore NCAA DI ATs’ perceptions of and experiences with the personal use of psychosocial strategies and sport psychology services to manage their stress, improve their …


A Study Of The Effect Of Physiological Stressors On Hypothalamic Regulation Of Reproduction Using An In Vitro System, Lisa L. Amelse May 2022

A Study Of The Effect Of Physiological Stressors On Hypothalamic Regulation Of Reproduction Using An In Vitro System, Lisa L. Amelse

Doctoral Dissertations

Stressors have a negative impact on reproductive efficiency in humans and other animals, which has an economic cost due to infertility treatments for humans and reduced income for food producers. We wished to determine the molecular pathways by which metabolic disturbances and low-level inflammation impact the hypothalamic pituitary gonadal (HPG) axis using an in vitro model. To this end, we used the GT1-7 cell line, an immortalized line expressing the Kiss1R receptor that responds to kisspeptin stimulation with the release of GnRH to assess the impact of stressors on the GnRH-releasing cells. Additionally, we used the KTaV-3 and KTaR-1[A1] …

Social Status Modulates Restraint- Induced Neural Activity In Brain Regions Controlling Stress Vulnerability , Sahba Seddighi, Matthew A. Cooper Oct 2017

Social Status Modulates Restraint- Induced Neural Activity In Brain Regions Controlling Stress Vulnerability , Sahba Seddighi, Matthew A. Cooper

Haslam Scholars Projects

Understanding the cellular mechanisms that control resistance and vulnerability to stress is an important step toward identifying novel targets for the prevention and treatment of stress-related mental illness. Dominant and subordinate animals have been shown to exhibit different behavioral and physiological responses to stress, with dominants often showing stress resistance and subordinates often showing stress vulnerability. We have previously found that dominant hamsters exhibit reduced social avoidance following social defeat stress compared to subordinate hamsters, although the extent to which stress resistance in dominants generalizes to non-social stressors is unknown. In this study, dominant, subordinate, and control male Syrian hamsters …

Effect Of Omega-3 Polyunsaturated Fatty Acid (N-3 Pufa) Supplementation To Lactating Sows On Growth And Indicators Of Stress In The Post-Weaned Pig, John M. Mcafee Dec 2016

Effect Of Omega-3 Polyunsaturated Fatty Acid (N-3 Pufa) Supplementation To Lactating Sows On Growth And Indicators Of Stress In The Post-Weaned Pig, John M. Mcafee

Masters Theses

The first experiment was designed to determine the concentration of protected fish oil product (PFO), as GromegaTM, to be added that would sufficiently decrease the polyunsaturated fatty acid (PUFA) ratio in the sows’ milk and colostrum. Of the 3 diets tested (0.25%, 0.5% and 1%) with a control (0% PFO), only the 1% PFO diet had an effect on the PUFA concentrations. The docosahexaenoic acid (DHA) concentration tended (P = 0.05) to be greater in the 1% PFO diet for both colostrum and milk samples. A second experiment was designed to …


A Comparison Of Salmonella Enterica Serovars: Are Prevalence, Virulence And Responses To Environmental Conditions Serovar Or Strain Dependent?, Nan Zhang Aug 2013

A Comparison Of Salmonella Enterica Serovars: Are Prevalence, Virulence And Responses To Environmental Conditions Serovar Or Strain Dependent?, Nan Zhang

Masters Theses

Salmonella are considered the leading cause of foodborne illnesses with frequent outbreaks in United States. While more than 2500 serovars have been identified, Salmonella Typhimurium and Salmonella Enteritidis are primarily responsible for most human infections while Salmonella Kentucky and Salmonella Heidelburg are currently the most prevalent serovars associated with poultry contamination. The relationship between virulence and prevalence is not fully understood, but may be a result of environmental stress exposure such as acid stress. In this research, organic acid (acetate) and inorganic acid (hydrogen chloride) were applied to 15 different serovars isolated from human infections or poultry. The growth curves …


“Everything Was Different”: An Existential Phenomenological Investigation Of Us Professional Basketball Players’ Experiences Overseas, Rainer Josef Meisterjahn May 2011

“Everything Was Different”: An Existential Phenomenological Investigation Of Us Professional Basketball Players’ Experiences Overseas, Rainer Josef Meisterjahn

Doctoral Dissertations

Globalization in the sports world is a phenomenon that has received considerable attention in the sport studies literature (Maguire, 1994, 2004). A significant aspect of globalization is labor migration in professional sports, which has been investigated extensively in recent years (e.g., Magee & Sugden, 2002; Takahashi & Horne, 2006). Basketball is one sport that has been discussed in this context (Falcous & Maguire, 2005). The sports encounters of athletes in foreign cultures are often diverse and entail differing pressures, rewards, and interdependencies (Falcous & Maguire, 2005). Players may deal with significant stressors such as performance expectations as is typical of …

Effect Of Social Status On Behavioral And Neural Response To Stress, Daniel W. Curry, Kathleen E. Morrison, Matthew A. Cooper

Senior Thesis Projects, 2009

Individuals respond differently to traumatic stress. Social status, which plays a key role in how animals experience and interact with their social environment, may influence how individuals respond to stressors. In this study, we used a conditioned defeat model to investigate whether social status alters susceptibility to the behavioral and neural consequences of traumatic stress. Conditioned defeat is a model in Syrian hamsters in which an acute social defeat encounter results in a long term increase in submissive behavior and a loss of normal territorial aggression. To establish social status, we weight matched and paired Syrian hamsters in daily aggressive …

Ethological Causes And Consequences Of The Stress Response, Neil Greenberg, James A. Carr, Cliff H. Summers

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

Stress involves real or perceived changes within an organism or in the environment that activate an organism’s attempts to cope by means of evolutionarily ancient neural and endocrine mechanisms. Responses to acute stressors involve catecholamines released in varying proportion at different sites in the sympathetic and central nervous systems. These responses may interact with and be complemented by intrinsic rhythms and responses to chronic or intermittent stressors involving the hypothalamic-pituitary-adrenal axis. Varying patterns of responses to stressors are also affected by an animal=s assessment of their prospects for successful coping. Subsequent central and systemic consequences of the stress response include …
