Biological Sex Differences In The Monodelphis Domestica: Investigating Behavioral Responses In Environmental Enrichment And Conditioned Place Preference Paradigms, Katelynn M. Renteria May 2022

Biological Sex Differences In The Monodelphis Domestica: Investigating Behavioral Responses In Environmental Enrichment And Conditioned Place Preference Paradigms, Katelynn M. Renteria

Theses and Dissertations

The Monodelphis domestica, commonly known as the grey short-tailed opossum, has become an increasingly frequented animal model for areas of psychological study, including comparative psychology. Despite the growing interest in utilizing the Monodelphis as an animal model, several areas of research remain limited in what has been studied. This includes associative learning and the effects of environmental enrichment on the Monodelphis. This study novelly incorporates the two using environmental enrichment with the conditioned place preference (CPP) paradigm to both diversify associative learning literature and expand existing knowledge on the Monodelphis domestica. The CPP paradigm included interactive objects as environmental …

Nanomechanical Characterization Of Vascular Tissue Using Atomic Force Microscopy, Ana Isabel Delgado Peralta May 2022

Nanomechanical Characterization Of Vascular Tissue Using Atomic Force Microscopy, Ana Isabel Delgado Peralta

Theses and Dissertations

Cardiovascular morphogenesis and pathophysiology have been associated with the mechanical properties of the vessel wall. In this work, nanomechanical properties of diseased arteries and control groups were quantified using the Atomic Force Microscopy (AFM). Both tip sizes of 20nm and 5µm were used for examining the local and global stiffness. First, we measured the stiffness as a potential index factor of the mice’s aortic aneurysm. Results have shown the stiffness of mice aortic aneurysm is 58.84 ± 30.26 kPa, which is significantly different (P < 0.05) from the stiffness of the control group of 4.70 ± 17.41 kPa. This was attributed to the degradation of elastin fibers and increment of collagen deposition in the vessel as observed in the histological analysis. The lesion heterogeneity was illustrated by the stiffness gradient from 40 kPa to 1.2 MPa within a 2µm2 region. We also examined the stiffness of the diabetic rat aorta as a potential biomarker for disease progression. Results have shown a significantly higher stiffness of 70.25 ± 14.10 kPa in diabetic rat aorta, compared with 54.19 ± 14.15 kPa in the control group. Lastly, we characterized the human aortic calcifications to fill the knowledge gap of scarce datasets for calcification stiffness. Results have demonstrated the calcification stiffness as 61.5 ± 35 kPa, which is significantly larger than the stiffness of the control group of 12.0 ± 4.4 kPa. The stiffness variation was attributed to the percentage of calcium deposits, observed from the histological analysis. These nanomechanical characterizations could be further used for a better understanding of arterial adaptation and to provide insights for effective vascular therapies.

Holocene Human Influence In The Ecuadorean Amazon, Meghan Mary O'Connor May 2022

Holocene Human Influence In The Ecuadorean Amazon, Meghan Mary O'Connor

Theses and Dissertations

The extent to which the spectacular biodiversity of Amazonia has been shaped by Pre-Columbian humans is actively debated. Forests that today appear to be pristine wildernesses may have supported complex human societies as recently as 300 years ago. Understanding human history and the potential successional trajectories that result from site abandonment are important to conservation and policy-making. The Yasuni, is famed for its human and biological diversity and yet its pre-history is poorly known. Lake Añangucocha, a small blackwater lake in northwestern Ecuador, is unusual in that it is not a riverine lake, and has the potential to provide the …

Cellular Migration As A Function Of Magnetic Field Intervention, Amy Marie Vecheck May 2022

Cellular Migration As A Function Of Magnetic Field Intervention, Amy Marie Vecheck

Theses and Dissertations

This work aims to assess cellular migration in three-dimensional structures as a function of Zeeman resonance. By using Zeeman resonance to initialize intersystem crossing of electrons, also known as the Radical Pair Mechanism, bioenergetics processes would be modulated. Processes such as oxygen consumption rate and extracellular acidification rate are indicative of cellular respiration and glycolysis and can be altered based on the orientation of the magnetic field applied: parallel and perpendicular, respectively. This study focused on the parallel orientation and looked to used Zeeman resonance to increase flavin adenosine dinucleotide, which results in preventing the breakdown of F-actin. Cellular viability …

Metabolic Signatures Of Kin Recognition In The Model Angiosperm Arabidopsis Thaliana, Thiara Siqueira Bento May 2022

Metabolic Signatures Of Kin Recognition In The Model Angiosperm Arabidopsis Thaliana, Thiara Siqueira Bento

Theses and Dissertations

Many organisms have evolved to identify and respond to differences in genetic relatedness between conspecifics, allowing them to select between competitive and facilitative strategies to improve fitness. Due to their sessile nature, plants frequently draw from the same pool of nutrients, and the ability to limit competition between closely related conspecifics would be advantageous. Over the last 3 decades, significant evidence has accumulated in multiple species that such ‘kin recognition’ (KR) is indeed commonplace in plants. I propose that if KR has evolved, at least in part, as a plant-plant interaction to regulate nutrient uptake, then nutrients should modulate the …

A Spatiotemporal Bayesian Model For Population Analysis, Mohamed Jaber May 2022

A Spatiotemporal Bayesian Model For Population Analysis, Mohamed Jaber

Theses and Dissertations

Spatiotemporal population analysis based on incomplete, redundant, and unidentified observations is critically important, yet it is a very challenging problem. Different approaches have been proposed and several methods have been implemented to address this problem. Capture-recapture methods have been widely used and have become the standard sampling and analytical framework for ecological statistics with applications to population analysis. Despite the fact that capture-recapture methods have been commonly used, these methods do not consider the spatial structure of the population. Moreover, conventional capturerecapture methods do not use any explicit spatial information with regard to the spatial nature of the sampling and …

Nm-Rs Au Naturale: Investigations Into Simulating A Natural Environment, Jenna Pantophlet Apr 2022

Nm-Rs Au Naturale: Investigations Into Simulating A Natural Environment, Jenna Pantophlet

Theses and Dissertations

Naked Mole-rats (NM-Rs) have been studied in laboratories for decades due to their unique behavior and physiology. However, due to the scope and complexity of the NM-R’s natural subterranean tunneling system, it has been difficult to replicate in the laboratory environment. From a researcher’s perspective, optimal housing is cost- and space-efficient and easily cleaned. On the other hand, optimal animal welfare and husbandry encourages the most biologically relevant enclosure to evoke the fullest range of an animal's behavioral repertoire. While there is an abundance of works centered on the biomedical potential of these odd rodents (Buffenstein et al, 2012; Delaney …

Investigating The Function Of Play Bows In African Wild Dogs (Lycaon Pictus), Michael Spiotta Apr 2022

Investigating The Function Of Play Bows In African Wild Dogs (Lycaon Pictus), Michael Spiotta

Theses and Dissertations

Play bows are a recognizable communicative signal observed in many carnivores, most notably, members of the genus Canis. Various hypotheses have been set forth to describe the function of play bows within canid social play behavior. To date, evidence suggests that wolves (Canis lupus), domestic dogs (Canis familiaris), and dingoes (Canis lupus dingo) use this signal as a means to both initiate, as well as, resume play. These studies have not previously been replicated in members of the family Canidae who fall outside of the genus Canis. In this study, I analyzed …

Tidal Translations: Thinking-With Untranslatability In Craig Santos Perez's From Unincorporated Territory, Maryn Gardner Apr 2022

Tidal Translations: Thinking-With Untranslatability In Craig Santos Perez's From Unincorporated Territory, Maryn Gardner

Theses and Dissertations

Craig Santos Perez's poetic series from Unincorporated Territory describes and decries the U.S. militarization, colonization, and environmental degradation of Guam in the Western Pacific through multilingual, excerpted, and series-long poems. Perez's writing style requires slow, careful reading with translations sometimes appearing on the same page, various pages later, or not at all. I describe this kind of elongated translation as slow translation, recalling translation theorist Michael Cronin's "Slow Language" movement. This thesis invites readers, especially multispecies ethnographers, to slow down the translation of nonhuman species and their stories by paying attention to moments of untranslatability in multispecies literature and interactions. …

Communities Of Water: An Examination Of Cooperation And Conflict In Water Management Practices In The Central Peruvian Andes, Sylvie D. Littledale Apr 2022

Communities Of Water: An Examination Of Cooperation And Conflict In Water Management Practices In The Central Peruvian Andes, Sylvie D. Littledale

Theses and Dissertations

This thesis explores two examples of water management in the highland Peruvian villages, San Pedro de Llancha and San Antonio de Chinchina. One example is of cooperation and union between the two communities. The other is of conflict between the same two villages just 40 years prior. I examine ethnographic and ethnohistorical data from both the collaborative period and the conflictive period of these two communities’ relations over water. The data suggest that, while the outcomes of these two periods were drastically different, the processes through which these communities came into relation with one another were quite similar. Their communal …

Mindfulness And Observational Drawing, Corinne Christopherson Sonderegger Apr 2022

Mindfulness And Observational Drawing, Corinne Christopherson Sonderegger

Theses and Dissertations

Observational drawing has many benefits, yet it can be a difficult and frustrating curriculum for students and teachers alike. As I was teaching elementary and college art classes simultaneously, I noticed a significant discrepancy between my younger and older students. Students in my elementary art classes loved to draw and often expressed how excited they were to make art. However, students in my college art classes were more hesitant and self-conscious about drawing and did not believe they could progress artistically. Many of these students had abandoned drawing in elementary or middle school. This pattern evokes the U curve of …

Parental Incarceration As A Predictor Of Legal Cynicism, Mackenzie Joy Heim Apr 2022

Parental Incarceration As A Predictor Of Legal Cynicism, Mackenzie Joy Heim

Theses and Dissertations

Researchers have established that legal cynicism is linked to violence, deviant behavior, and crime. In response to the potentially dangerous implications of a legally cynical society, research in recent years has attempted to identify experiences and conditions that play a role in the development of legal attitudes. Given that youths' familial and social conditions appear to be influential predictors, this study tests the relationship between parental incarceration and legal cynicism. Data from the Fragile Families and Child Wellbeing Study were used for this analysis. Results from three OLS regression models indicate that parental incarceration is not a significant predictor of …

The Role Of Bacterial Genotype In The Persistence Of The Microbiota Of Drosophila Melanogaster, Sarah J. Gottfredson Apr 2022

The Role Of Bacterial Genotype In The Persistence Of The Microbiota Of Drosophila Melanogaster, Sarah J. Gottfredson

Theses and Dissertations

In this work we use the fruit fly Drosophila melanogaster as a model to identify bacterial genes that help bacteria to persist in their animal hosts. Early work on this model system established that dietary replenishment drives the composition of the D. melanogaster gut microbiota, and subsequent research has shown that some bacterial strains can colonize the fly for much longer than the flow of bulk diet through the gut. In this work we reveal that bacterial genes influence bacterial persistence by studying the correlation between bacterial genotype and persistence in the D. melanogaster gut microbiota. We performed an initial …

Blood, Tears, And Wounded Eyes: Holy Effluvia And The Compassion Of The Virgin In Early Modern Flemish Visual And Devotional Culture, Katharine Grace Davidson Bekker

Theses and Dissertations

Images of the Mater dolorosa, the weeping Mother of God mourning over her dead son, are plentiful art of Northern Europe during the fifteenth and sixteenth centuries and often foreground the shedding of effluvia—blood, sweat, and tears—in their depictions of the holy pair. This paper explores the visual themes of tears, blood, eyes, and wounds as vital actors in images that require close, meditative, and affective looking and engagement. Such image formats include small-scale pairings of the Man of Sorrows and Mater dolorosa as well as books of hours. In these contexts, the holy fluids and their bodily sources expand …

Using Movement To Infer Critical Life History Events In Mule Deer: Parturition And Natal Dispersal, Tabitha A. Hughes

Theses and Dissertations

The advent of GPS tracking technology has revolutionized the field of wildlife research. The ability to obtain fine-scale location data from collared animals allows for increased understanding of life-history events that have previously been difficult to research. An excellent candidate species for telemetry-based research is mule deer (Odocoileus hemionus). Mule deer are an important species economically due to their position as a harvested species. Additionally, they play an important role in the ecosystems they occupy; therefore information regarding important life history events would improve conservation and management efforts for this species. Our objectives were to use GPS tracking technology to …

Localized Heat Therapy Improves Mitochondrial Function In Human Skeletal Muscle, Erik D. Marchant Apr 2022

Localized Heat Therapy Improves Mitochondrial Function In Human Skeletal Muscle, Erik D. Marchant

Theses and Dissertations

Physical activity results in various types of stress in skeletal muscle including energetic, oxidative, and heat stress. Acute exposure to stress impairs skeletal muscle mitochondrial function. In contrast, chronic intermittent exposure to mild stress through exercise training results in increased mitochondrial content and respiratory capacity. While oxidative and energetic stress have received much attention regarding their long-term effect on skeletal muscle mitochondria, heat stress is not well understood. The purpose of this work was to investigate the effects of localized heat therapy on human skeletal muscle mitochondria, and to compare these effects to those of high-intensity interval exercise training.

Settler-Author Allyship In Centering Indigenous Ecologies: Communal Will Through Collective Environmental Guilt In This Tender Land And Caleb's Crossing, Elena Marie Arana

Theses and Dissertations

The January 2021 edition of PMLA housed an entire cluster on "Indigenous Literatures and the Anthropocene," in which at least four of the eight non-Indigenous contributors directly addressed and supported a call for learning from and collaborating with Indigenous voices. The unanimity of the discussion dissolves somewhat drastically when considering exactly how this should be done, leading Melanie Taylor to voice one of the framing questions of the cluster: "If it is increasingly clear that not all members of Anthropos are equal drivers of the Anthropocene, and that not all are uniformly compromised by its havoc, how can we begin …

The Novel Protein Crystallization Chaperone Telsam Stabilizes Weak Crystal Contacts, Accelerates Crystallization Of Fused Target Proteins, And Solves The Crystallographic Phase Problem, Supeshala Dilrukshi Sarath Nawarathnage Apr 2022

The Novel Protein Crystallization Chaperone Telsam Stabilizes Weak Crystal Contacts, Accelerates Crystallization Of Fused Target Proteins, And Solves The Crystallographic Phase Problem, Supeshala Dilrukshi Sarath Nawarathnage

Theses and Dissertations

We studied the usefulness of genetic fusion to TELSAM polymers as an effective protein crystallization strategy. We observed novel properties in crystals of two TELSAM-target protein fusions. TELSAM as a crystallization chaperone shows rapid crystallization when it's fused to target proteins and possibly with a greater propensity. Some TELSAM-target fusions crystallized more rapidly than the same target protein alone. TELSAM-target proteins can be crystallized at relatively low protein concentrations such as 0.1 mg/mL. TELSAM requires no TELSAM polymers touching one another in the crystal lattice in order to form well-diffracting crystals. This lack of crystal contacts has not been observed …

Using Connections To Make Predictions On Dynamic Networks, Rebecca Dorff Jones Apr 2022

Using Connections To Make Predictions On Dynamic Networks, Rebecca Dorff Jones

Theses and Dissertations

Networks are sets of objects that are connected in some way and appear abundantly in nature, sociology, and technology. For many centuries, network theory focused on static networks, which are networks that do not change. However, since all networks transform over time, static networks have limited applications. By comparison, dynamic networks model how connections between objects change over time. In this work, we will explore how connections in dynamic networks change and how we can leverage these changes to make predictions about future iterations of networks. We will do this by first considering the link prediction problem, using either Katz …

Aiding Semantic Memory Creation With Navigational Context, Thomas Benjamin Lyle Wasden Apr 2022

Aiding Semantic Memory Creation With Navigational Context, Thomas Benjamin Lyle Wasden

Theses and Dissertations

While we have traditionally understood the hippocampus to be involved in memory and navigation, it also appears that it has a role in language processing, creation and prediction. An obvious explanation for this is that language is impossible if linguistic signs cannot be remembered and retrieved. Because linguistic signs are definitionally biologically neutral or arbitrary, we must use the brain's apparatus for learning and storing information from the external world to store and retrieve them. Although plausible, this explanation fails to take into account the hippocampus' role in navigation as a contributing element in the processing, storage and retrieval of …

Comparative Sequence Analysis Elucidates The Evolutionary Patterns Of Yersinia Pestis In New Mexico Over Thirty-Two Years, M. Elizabeth Warren

Theses and Dissertations

Yersinia pestis, a gram-negative bacterium, is the causative agent of plague. Y. pestis is a zoonotic pathogen that occasionally infects humans, and is endemic in the western United States. History gives evidence of three main plague pandemics. The first, originating in Egypt in 541AD, is known as the Justinian plague. The second, perhaps most well-known, is thought to have emerged in 1347AD in China, and is called the Black Death. The third, and current plague pandemic, also emerged in China in 1855. In 1899, Y. pestis was established in California, and the plague in other parts of America evolved from …
