Stage-Structured Predator-Prey Interactions In A Warming World: A Case Study In Riverine Rock Pools, Andrew T. Davidson Jan 2023

Stage-Structured Predator-Prey Interactions In A Warming World: A Case Study In Riverine Rock Pools, Andrew T. Davidson

Theses and Dissertations

Warming can impact predator-prey interactions through a variety of mechanisms. For example, warming can both alter the rate at which predators consume prey and the rate prey develop through vulnerable life stages. Thus, the overall effect of warming on consumer-resource interactions will depend upon the strength and asymmetry of warming effects on predator and prey performance. Here, we describe the consequences of these asymmetrical responses to temperature by first developing a simple stage-structured modeling framework, then applying that framework to predation of American rock pool mosquito larvae, Aedes atropalpus, by several common predators in riverine rock pools. We then …


Climate, Physiology, And Distributions: The Role Of Thermal Physiology In Biological Invasions, Sean D. Powers Jan 2023

Climate, Physiology, And Distributions: The Role Of Thermal Physiology In Biological Invasions, Sean D. Powers

Theses and Dissertations

Climate is a primary factor influencing species range dynamics, particularly for ectotherms whose body temperature is closely tied to the surrounding conditions. While range shifts of ectotherms are attributed to climate warming, the mechanism driving these shifts are not well understood. Studies in macrophysiology demonstrate that the interaction of climate with thermal physiology plays a key role in determining large-scale spatial and temporal patterns for many temperature-sensitive physiological traits. This work has revealed a clear relationship between thermal tolerance breadth and range size. However, more recent analyses of this relationship demonstrate that thermal tolerance breadth only provides a partial explanation …


Hmong Parent Engagement: The Need To Provide Basic Needs Services In Hmong Charter Schools To Increase Parent Engagement, Kevin Xiong Jan 2023

Hmong Parent Engagement: The Need To Provide Basic Needs Services In Hmong Charter Schools To Increase Parent Engagement, Kevin Xiong

Theses and Dissertations

The Hmong diaspora and settlement in the United States have a direct impact on how Hmong parents engage in their children’s academic journey. With the viewpoint of traditional Westernized parent engagement, Hmong parents may be perceived as engaging too little. However, in order for Hmong parents to be involved in their children’s educational journey as part of this Westernized concept, it is imperative that the families’ basic needs are met. Otherwise, they will primarily focus on meeting their fundamental basic needs rather than being engaged in their children’s academic progress. This research explored two Hmong charter schools in the Twin …

Intracranial Mast Cell Activation And Central Histaminergic Dysregulation In Food Allergy-Associated Neuropathology And Behavioral Changes, Danielle Germundson-Hermanson

Theses and Dissertations

Food allergy occurs when the immune system reacts inappropriately to an otherwise harmless food. The hypersensitivity response is known to cause physical symptoms ranging from mild gastrointestinal discomfort to life-threatening anaphylaxis. Curiously, there is growing evidence that some food-allergic individuals experience changes in mood and behavior after consuming an offending food despite not experiencing severe physical symptoms. However, the mechanism(s) through which food allergy may affect the brain and behavior has yet to be elucidated. Previously, we found that inducing non-anaphylactic cow’s milk allergy (CMA) in mice resulted in abnormal behavior, neuroinflammation, and an increased the number of brain mast …


A Deep Review Of Sustainable Approaches For Hydrogen Production For Energy Generation, Patrick Bernard Ferron Jan 2023

A Deep Review Of Sustainable Approaches For Hydrogen Production For Energy Generation, Patrick Bernard Ferron

Theses and Dissertations

Fossil fuel energy sources such as coal, oil, and natural gas produce greenhouse gases upon combustion. Over time the greenhouse gases trap heat in the atmosphere and cause global temperatures to continually increase. This continued rise in global temperatures has led to severe climate conditions that have resulted in increasing environmental, financial, social, and medical issues. To mitigate the rise in global temperatures, and the negative effects associated with it, the carbon intensity of our energy sources must be substantially reduced or eliminated where possible. In addition, alternate sources of carbon-free energy sources must be pursued and implemented. Hydrogen is …

Black Midwives For Black Mothers: Ameliorating Racial Disparities In The Quality Of Maternal Healthcare, Kimberly Navarro Jan 2023

Black Midwives For Black Mothers: Ameliorating Racial Disparities In The Quality Of Maternal Healthcare, Kimberly Navarro

Theses and Dissertations

In the United States, maternal mortality represents a dire health crisis with a stark racial imbalance. Black women are two and a half to three times more likely to die from pregnancy and birth-related complications than their White counterparts. Racial disparities in maternal health can be explained by variations in the quality of maternal healthcare services that women tend to receive. Racial and ethnic minority women are more likely to receive inferior quality prenatal care (PNC), which brings to question the care model of traditional PNC and its adequacy in serving the healthcare needs of Black women. Since Black women …

Formation Of Vasculogenic Mimicry: Role Of Melanoma Differentiation Associated Gene-9 In Human Melanoma, Jinkal Shah

Theses and Dissertations

Malignant melanoma (MM) is the most aggressive skin cancer and the most frequent skin disorder in Caucasians. MM is associated with aggressive and progressive disease states, leading to major cancer-related morbidity and mortality. Recent investigations identify an alternative pathway -vasculogenic mimicry (VM), which is considered a cancer hallmark that can independently facilitate tumor neovascularization by the formation of fluid-conducting and vascular endothelial cells. MM cells undergoing VM can dedifferentiate into numerous cellular phenotypes and acquire endothelial-like features, resulting in the formation of the de novo matrix-rich vascular-like networks, such as plasma and red blood cells. The co-generation of endothelial cells, …


Exploring The Effect Of Early Motor Delay And Physical Therapy Interventions On The Parent-Child Relationship, Rebecca Molinini Jan 2023

Exploring The Effect Of Early Motor Delay And Physical Therapy Interventions On The Parent-Child Relationship, Rebecca Molinini

Theses and Dissertations

Emotional availability (EA) or the ability of the parent-child dyad to engage emotionally and partake in congruent and mutually enjoyable interactions, is essential for familial health and well-being. EA is considered the “connective tissue” of healthy parent-child relationships and is associated with secure attachment, maternal mental health, and children’s adaptive development. Most evidence supporting the integral role of EA on healthy outcomes is supported by typically developing populations in which adults present with a social or biological risk factor such as experiencing past traumas of adversities with mental health. In line with the transactional model of development, children are equal …
