Polycyclic Aromatic Hydrocarbons And The Microbiomes Of Two Benthic Species, Samantha Ells

Master's Theses

The presence of oil has been shown to affect the microbiomes of the water column, sediments, and organisms, both by altering the diversity and the composition of those microbial communities. If the microbiome is altered it may no longer provide benefits to its host organism, impacting its ability to survive. Thus, it is important to understand the effects of large-scale contamination events including the Deepwater Horizon oil spill. This study set out to examine the effects of oil exposure on the microbiome of two benthic species, southern flounder (Paralichthys lethostigma) and eastern oysters (Crassostrea virginica) to further understand the effects …

Characterization Of The Bacterial Microbiome Of Exotic Tick Species Collected From Migratory Birds, Raima Sen

Master's Theses

Migratory birds often serve as natural/accidental hosts to ectoparasites like ticks (predominantly immature stages) and are known reservoirs of several pathogens transmitted by ticks. Parasitizing these birds, exotic tick species often hitch rides to non-native ecological niches, bringing along tick-borne pathogens. This study aims to profile the bacteriome of exotic tick species flying in and out of the US from the Neo-tropical South. A total of 421 tick samples comprised of several different tick species were collected off migratory songbirds at sites north of the Gulf of Mexico (Louisiana State). A 16S rRNA metagenomic multiplexed sequencing approach was used to …

Comparison Of Animal Versus Plant-Based Protein Supplementation To Nitrogen Balance In Female College Students, Adeline Maykish

Master's Theses

Plant-based diets have become popular in the past 10 years, with approximately 11% of Americans self-identifying as vegan or vegetarian, and many others trying to reduce meat consumption. Due to this increasing interest, the plant-based food market has exploded with several novel innovative products serving as alternatives to animal-based products. One such example is almond protein powder, a fairly new protein supplement created as an alternative to whey protein. A number of studies have compared animal-based protein supplementation, such as whey to plant-based supplementation, such as soy, on muscle protein synthesis and skeletal muscle preservation. Due to the novelty of …

Analyzing The Consistency Of Scoring Porotic Hyperostosis From 3d Scans, Carson Rouse

Master's Theses

The use of 3D scans is becoming more and more common in the field of bioarchaeology. They alleviate the need to travel, allow for larger sample sizes, and can help preserve bones with pathologies on them which make them more fragile. Though there are major benefits with using 3D scanning of human remains, there is a lack of studies which examine whether or not traditional pathology scoring methods can be used to consistently gather the same data from these 3D scans. This project examines how consistently six researchers of varying experience levels scored porotic hyperostosis from 25 3D scans on …

Subadult Cortical Bone Analysis As An Indicator Of Childhood Health Status Among The Tipu Maya Population, Jaime Thomas

Master's Theses

This thesis explores juvenile health at the contact Maya site of Tipu in western Belize. The associated cemetery was excavated and provided a large and well-preserved population. Although Tipu has been a focus of many studies, few studies have focused on subadults and none on their cortical development, which can allow insight into access to necessary nutritional resources.

Some 108 femora belonging to individuals aged birth to 13 years with femora previously sectioned at midshaft provided the sample. External dimensions taken included diaphyseal length, circumference, medial-lateral diameter and anterior-posterior diameter. Additionally, cortical thickness was measured at four points, and 95 …

Urban Agroecology For Food Sovereignty And Biodiversity: Are Urban Community Farms Or Gardens More Effective?, Heidi L. Giancola

Master's Theses

Industrial agriculture is accurately criticized for eliminating biodiversity and destroying food sovereignty. Urban agroecosystems, usually individual plots in community gardens, are promoted to restore ecological services and equity to food systems. Recently, collectively tended urban community farms have developed, with explicit social justice goals. This study directly contrasts the effectiveness of the urban community farm and garden models. Spatial analysis is used to confirm that community farms enhance geographic access for healthy food priority areas compared to gardens in the San Francisco bay area. An online survey of farm staff and gardeners from Marin to Santa Clara County resulted in …

The Relationship Between Different Forms Of Exercise And Adhd Symptomatology, Matthew A. Reynolds

Master's Theses

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder associated with executive function deficits as well as negative life outcomes in both childhood and adulthood. Current treatments to reduce symptoms of ADHD include stimulant medications that act as catecholamine agonists. These medications often cause undesirable side effects, to which end better understanding the effects of non- pharmacological treatments on symptoms of ADHD is critical. Research conducted in children suggests that exercise may be an effective tool for symptom reduction. However, the relationship between exercise and ADHD symptoms remains unclear for adults. The aim of this study was to address this …

Do Conditional Cash Transfers Increase School Enrollment? Evidence From Brazil, Jeanette L. Silvernale

Master's Theses

Conditional cash transfer programs have been widely deployed across the globe. They seek to bolster human capital by providing benefits contingent upon a variety of actions such as school attendance and regular health checkups. Bolsa Familia is the most extensive conditional cash transfer program, serving 46 million Brazilian citizens. Despite its expansive size, there have been seldom large-scale micro evaluations of the program. Limited data has resulted in small sample sizes drawn from a single point in time. Our study diverges from the rest and utilizes a novel administrative dataset with an overall sample of nearly 60 million and a …

Cattle Producer Motivations And Willingness To Participate In Industry Animal Welfare Program Verification, Chase Decoite

Master's Theses

As consumers have become increasingly interested in where their food comes from and how it is grown, the cattle and beef industry is without exception. Many consumers are beginning to question traditional animal husbandry practices and on-farm animal welfare protocol. It is essential that the food system meets new demands and understands consumer views. In order to address these concerns, the industry has rallied around the Beef Quality Assurance (BQA) program to set the standard for cattle welfare and beef quality, with the explicit goal of improving consumer confidence. The goal of this research is to determine if cattle producers …

Insects As A Sustainable Food Ingredient – Utilization Of Carrot Pomace, Identification Of Early Adopters, And Evaluation Of Mealworm Acceptability, Dominic Rovai

Master's Theses

Insects have been proposed as a sustainable alternative to livestock to help feed the growing population. Edible insects such as mealworms require less land and resources and can utilize food by-products to grow. While insects are consumed by over 2 billion people worldwide, they are not widely accepted in developed countries like the United States because of their unfamiliarity and the perception of disgust associated with entomophagy. The objectives of this research are to 1) grow mealworms using carrot pomace and determine an optimum diet for growth and nutritional composition, 2) identify and classify early adopters of insects, and propose …

Effects Of Plant Growth-Promoting Bacteria And Fungi On Strawberry Plant Health, Fruit Yield, And Disease Susceptibility, Mary Maher

Master's Theses

Studies on plant growth-promoting rhizobacteria (PGPR) and fungi (PGPF) as biostimulants have shown significant positive effects on plant health, fruit yield, or pest management. However, very few published studies to date have been specific regarding their effects on strawberries (Fragaria × ananassa), particularly on soilborne disease prevalence in organically grown strawberries. Empirical data on the results of using these products in commercial growing applications under various conditions would be highly valuable, especially for organic growers who have limited synthetic chemical pesticides, herbicides and fertilizers registered for use. The objective of this study is to evaluate the efficacy of …

Development Of A Portable Low-Moisture Food Pasteurization Device Using Rf Heating, Eric Jason Ohata

Master's Theses

Bacterial presence in low-moisture foods such as flour, cereals, baby formula, and spices, have become a concern due to sanitizing challenges. The food industry currently focuses on wet food sanitation as opposed to low-moisture foods because of bacteria’s inability to reproduce in low water activity media. Traditionally, food processing RF heating pasteurizes in mass quantities while an equivalent consumer device does not exist the market today. A consumer product would help eliminate food waste by providing an easy way to sanitize food and extend shelf life. The Portable Food Pasteurization (PFP) project is an interdisciplinary project involving the Electrical Engineering, …

Evaluation Of Masculinization Treatments To Produce Feminized Hemp Seed (Cannabis Sativa L.), Ted Fitzgerald, J. Wyatt Brown

Master's Theses

Cannabis sativa L. (hemp) develops plants with either male or female flowers, and growers of hemp greatly prefer female flowers which bear the glandular trichomes that contain cannabinoids. Feminized (all female) seeds are highly desired, which are produced by crossing a female plant with a masculinized female plant. Masculinization is achieved through the inhibition of ethylene and/or addition of gibberellins before flower initiation in female plants. The hemp industry uses silver thiosulfate (STS) to masculinize hemp, but spraying silver poses environmental concerns. This study compared STS to three other ethylene-inhibiting agents: aminoethoxyvinylglycine (AVG), cobalt nitrate (CBN), and 1-methylcyclopropene (1-MCP). Treatments …

By researching the DSP role from the DSP experience directly, this study examines other factors that contribute to …

Do Letters And Gifts From International Sponsors Affect Child Outcomes? Evidence From Colombia, Ghana, And Haiti, Mai Moua

Master's Theses

Past research has found child sponsorship results in higher aspirations, mental health, and educational outcomes. In this research, I explore the extent to which these outcomes can be influenced by letters and gifts sent from the sponsor to the child. However, there is limited research on the effects of direct relationship between sponsor and child. Using 1142 sponsor letters and a 2017 survey from Compassion International, an international child sponsorship organization, we find that letters and gifts from sponsors have a statistically insignificant impact on outcomes including education, mental health, aspirations, social connectedness, nutrition, religiosity, hygiene, and views on drugs, …

Alliance Building In The Food Sovereignty Movement: Perspectives From Activists Advocating For Farmworker Justice And Agrarian Justice, Sarah Ruszkowski

Master's Theses

The food sovereignty movement has come to encompass a wide-range of constituent groups, all with unique perspectives and interests. While some of these groups’ goals align naturally, others present priorities differently, namely organizations that advocate for farmworker justice and those that advocate for agrarian justice. Because of the power imbalance embedded in this relationship as well as the racist, patriarchal, and neoliberal nature of agrarian capitalism, it can be challenging to navigate an equitable path forward. In this thesis, I examine whether and how food sovereignty as a broader umbrella movement is generative towards building ties between advocates for farmworker …

Wicked Problems: Understanding How Cities And Counties In California Are Tackling Climate Change And Homelessness, Guadalupe Michelle Franco

Master's Theses

California continues to endure the detrimental effects of climate change, such as poor air quality, flooding, and heatwaves. Concurrently, the state has seen an increase in the number of unhoused communities due to various ramifications such as rapid urbanization, failed political leadership, and restricted housing policies. While unhoused communities fight to access basic services, they must also now adapt to the looming impacts of climate change. Unhoused populations are especially vulnerable to climate change as they have limited access to shelter, spend the majority of their time outdoors, and lack the economic ability to adapt. While cities and counties are …

How Historic Shipwrecks Influence Dispersal Of Deep-Sea Microbiomes, Rachel Moseley

Master's Theses

This thesis investigates how historic shipwrecks potentially shape dispersal of deep-sea microbiomes. Processes impacting dispersal of microbiomes around artificial structures in the ocean and how they connect to other deep-sea habitats is unknown. Dispersal processes are explained for some macroorganisms by theories in ecology, specifically the Theory of Island Biogeography and the Wooden Stepping Stone hypothesis. These have not been investigated for microorganisms, and thus this work will probe if they are applicable to microbial biogeography in this habitat. Experiments were conducted to establish new “island-like” features in near proximity (25-125 m) to wooden-hulled historic shipwrecks in the northern Gulf …

Trophic Ecology Of Mesopelagic Fish Larvae And Juveniles In The Northern Gulf Of Mexico, Emily Gipson

Master's Theses

The deep-pelagic environment encompasses ocean waters below 200 m depth, and comprises 90% of the volume of the Gulf of Mexico. Deep-pelagic fishes are important prey for many oceanic consumers, but relatively little is known about their early life history, including larval fish trophic ecology. An understanding of the role deep-pelagic fish larvae have in oceanic food webs is important in the development of ecosystem models that examine the connectivity (via vertical migrations) between the deep-pelagic and epipelagic environments with respect to trophic interactions, nutrient cycling, and carbon sequestration. In this study, archived plankton samples collected during 2010 and 2011 …

The Effects Of A Loaded Pre-Competition Activity Using Tethered Swimming On 25-Yard Swim Sprint Performance 2021, Jacob Burchfield

Master's Theses

Warmup is a standard practice for swim competitions, but there is minimal scientific evidence regarding the effectiveness of pre-competition activities (PCA) after the swim warmup. This study examined whether a loaded PCA using tethered swimming while attached to a power rack improves performance in a 25-yard swim sprint. Post activation performance enhancement (PAPE) may be the proposed mechanism for improvement resulting from a loaded PCA. To determine if PAPE existed following the loaded PCA, varsity swimmers from SUNY Cortland performed a 25-yard sprint a loaded PCA and after an unloaded PCA (control). All participants performed a standard meet warmup (1600-yards) …

Indirect Impact Of Soil Microbial Communities On Plant-Aphid Interactions, Zachary Tiemann

Master's Theses

The community dynamics of soil micro-environments are influenced by root, fungal, and bacterial exudates that can preferentially select for functional classes of microbes. Arbuscular mycorrhizal fungi (AM) fungi and plant growth promoting rhizobacteria (PGPR) are members of this community form symbiotic relationships with plants and play an important role in triggering induced systemic resistance (ISR), resulting in defensive “priming.’ Consequently, ‘primed’ plants can activate stronger and faster defense responses to future attacks by pathogens and insects. The biological system in this study involved four genotypes of barrel medic plants (Medicago truncatula), pea aphids (Acyrthosiphon pisum), and microbial communities present in …
