An Integrated Evaluation Of Trace Mineral Status, Regional Variation, And Supplementation Effects On Circulating Mineral And Reproductive Performance In American Plains Bison, Bailey M. Rodriguez

Electronic Theses and Dissertations

The continued expansion of the American Plains Bison (Bison bison) industry has increased the need for science-based nutritional recommendations tailored specifically to the species, due to limited species-specific research. Because trace minerals influence immune function, growth, and reproductive performance, establishing baseline mineral status and evaluating responses to supplementation are critical for advancing bison production and conservation efforts. This thesis integrates two complementary investigations to evaluate trace mineral status in American Plains bison at both regional and herd management levels. First, a herd level comparison evaluated the influence of differing mineral supplementation strategies on circulating mineral concentrations, herd performance, and reproductive …

Winter-Feeding High Forage Vs. High Concentrate Diets To Beef Cows: Effects On Placental Transcriptomics, Lactation Capacity, And Enteric Methane Emissions, Megan Ann Wehrbein

Electronic Theses and Dissertations

Nutritional management and lactation performance are critical factors influencing productivity in cattle. This research includes two complementary studies. The first study was a meta-analysis to develop a lactation curve for Bos taurus cattle in North America using data from machine or hand milked cows. Data from 7 studies were used resulting in 1340 cow-day observations. Milk yield was analyzed by parity (primiparous or multiparous) and feeding management (non-nutrient restricted or nutrient restricted), revealing that primiparous cattle peaked earlier and at lower yields than multiparous cattle, and nutrient restriction reduced peak milk yield. Overall, Bos taurus cattle followed lactation trends similar …

We assessed trajectories and predictors of hydration using urine flow rate (UFR) and specific gravity (SG). Likewise, we examined trajectories and predictors of mono-n-butyl phthalate (MBP), for which concentrations were unstandardized or standardized via …

The Critical Role Of Near-Surface Dynamics In Identifying Spawning Areas Of Atlantic Bluefin Tuna In The Gulf Of Mexico, Donald R. Johnson, William J. Teague, Harriet Perry, James S. Franks

Gulf and Caribbean Research

Atlantic Bluefin Tuna, Thunnus thynnus (ABFT), migrate long distances to broadcast spawn in the Gulf of Mexico (GOM) basin, the Mediterranean Sea and the Slope Sea (NW Atlantic). These areas have commonalities including a highly dynamic upper ocean eddy environment that draws nutrients from shallow thermoclines and adjacent continental shelves and can provide temporal sanctuaries from some larval predators. In the GOM basin, the Loop Current (LC) and its energetic spin—off eddies sweep weak swimming predators such as jellyfish (Pelagia noctiluca) into lines and aggregations, leaving relatively open areas as temporal sanctuaries for ABFT larvae during the vulnerable …

Oyster Drill (Stramonita Haemastoma Complex) Habitat Preferences In A Shallow Coastal Estuary, Coen Mcgarrah, Cynthia Lupton, Eric Sparks, Jennifer L. Debose

Gulf and Caribbean Research

Southern oyster drill snails (Stramonita haemastoma complex) are nuisance organisms within the Gulf of Mexico. This is due to their damaging impact on recovering and farmed oyster (Crassostrea virginica) populations, which are one of the drills’ main food sources. Oyster reef recovery and increased aquaculture production are priorities for Mississippi and the wider northern Gulf coast. The Grand Bay National Estuarine Research Reserve (NERR) hosts multiple oyster reef restoration sites within its boundaries, yet no comprehensive survey of oyster drill abundance has been conducted in this area to date. Additionally, knowledge of oyster drill preferences for sediment …

Pollutant Load Reduction In Sarasota Bay, Florida (Usa): Target Development, Implementation, And Outcomes, David Tomasko, Mike Wessel, Jon Perry, Chris Anastasiou, Ryan Gandy

Gulf and Caribbean Research

Between 2006 and 2012, seagrass coverage across Sarasota Bay expanded by 1,108 ha, a 28% increase. During the subsequent years of 2012−2020, 830 ha of seagrass were lost, a 16% decline. In response to these findings, resource management efforts focused on determining the likely reason(s) why those 2 periods had such contrasting trends, to come up with strategies to reverse these losses. Based on results from the seagrass data, the 7—y period of 2006−2012 was designated a “reference period” and water quality data were compared against the subsequent 7—y designated “degraded period” of 2013−2019. Annual average chlorophyll-a (chl-a …

Ellmer School of Nursing Faculty Publications

Background: Short sleep and formula feeding during infancy are associated with increased risk of childhood obesity. Feeding practices and sleep arrangements vary during infancy and may also be dynamic, yet their impact on infant night sleep duration remains unclear. Understanding these relationships is crucial for formulating recommendations to support breastfeeding and address sleep concerns. Objective: We examined the association between feeding mode and parent-reported infant night sleep duration during the first postnatal year, while additionally evaluating night-weaning and bedsharing as contextual sleep-related practices. Methods: Infants in the Phoenix Metropolitan Area (n = 193) were followed up at 3, 8, 13, …

Estrogen Deprivation During Primate (Papio Anubis) Pregnancy: Impact On Systemic Microvascular Flow And Cardiovascular Development And Function After Birth In Offspring, Sifa Turan, Jeffery S. Babischkin, Graham W. Aberdeen, Gerald J. Pepe, Eugene D. Albrecht

Department of Biomedical and Translational Sciences Faculty Publications

Background

Suppressing estradiol (E₂) during baboon pregnancy lowers offspring skeletal muscle capillary density, vital for insulin-mediated glucose uptake, and induces insulin resistance. We examined whether E₂ deprivation also impairs microvascular flow and cardiac function.

Methods

Offspring of untreated baboons, letrozole-treated baboons, or letrozole plus E₂ (maternal s.c. injections during the second half of gestation) underwent contrast-enhanced microbubble ultrasonography to quantify microvessel flow and echocardiography to assess cardiac performance.

Results

Letrozole reduced maternal serum E₂ by 95% (p <  0.01). In letrozole offspring, microbubble flux rate (β) fell 55% (p <  0.02), replenishment was 5 s slower (p <  0.03), and microvessel flow declined 40% (p = 0.05); all were restored by added E₂. Indices of systolic (isovolumic contraction), diastolic (isovolumic relaxation), global performance (Tei index), and cardiac output were unchanged.

Conclusion

Prolonged gestational E₂ deprivation programs a reduction in microvascular flow without altering cardiac function; maternal E₂ prevents this, supporting E₂'s role in …

Element-Based Predictive Modeling Of Hydrothermal Liquefaction Bioproducts Derived From Corn Stover, Isamu Umeda, Meicen Liu, Yi Zheng, Jiefu Wang, Zhiwu Wang, Sandeep Kumar

Civil & Environmental Engineering Faculty Publications

The hydrothermal liquefaction (HTL) process offers an energetic advantage over pyrolysis because it does not require prior drying of the biomass feedstock. However, there are significant challenges in simultaneously estimating both the yields and characteristics of products from the HTL of biomass with theoretical support. This study developed a unique element-based kinetic model to predict the yields, higher heating values, and fuel characteristics of solid residue and heavy bio-oil, based on the temperature, residence time, solid loading, and elemental composition (C, H, N, and O) of corn stover. Furthermore, the model predicted the weights of dissolved carbon and nitrogen in …

Tobin, Rhonda G. Kost, U. Erdbrügger

Department of Biomedical and Translational Sciences Faculty Publications

Objectives

Urinary extracellular vesicles (uEVs) are potential biomarkers for renal physiology and disease. Their isolation is challenged by Tamm-Horsfall protein (THP) contamination, particularly in high-speed ultracentrifugation (P100) fractions. Low-speed (P20) fractions contain biologically relevant uEVs, yet their proteomic composition is underexplored. This study evaluates strategies for THP removal to optimize mass spectrometry analysis and characterizes P20 and P100 uEV proteomes and its combination in healthy urine.

Methods

Urine from a healthy volunteer was processed via sequential centrifugation at 21,200 g (P20) and 164,244 g (P100). THP removal was performed using low ionic strength buffer (P20) and size-exclusion chromatography (P100). Western …

Ovarian carcinoma and malignant melanoma are the first human tumors where immune responses, primarily restricted to autologous tumor cells, were first demonstrated. T-cell lines and clones developed in recombinant interleukin-2 (rIL-2) from tumor-infiltrating lymphocytes (TIL) from these tumors exhibited cytotoxicity and/or cytokine production, primarily restricted to autologous tumor cells. The T-cell receptor (TCR) and the CD3 differentiation antigen on effector T cells and HLA on …

Bayesian Multivariate Modelling Of Lone Star (Amblyomma Americanum) Tick Life Stage Abundance And Temporal Trends To Inform Public Health Risk In Virginia, Thabo Lephoto, Henry Mwambi, Oliver Bodhlyera, Holly Gaff

Biological Sciences Faculty Publications

The increasing abundance of ticks poses a growing public health concern due to heightened human exposure to tick bites. The lone star tick (Amblyomma americanum: Ixodida: Ixodidae), a common human-biting species in the United States, has expanded its range in recent years. However, how its different life stages vary across time, habitats, and locations remains insufficiently understood. We analyzed tick abundance data collected in southeastern Virginia between 2009 and 2018, focusing on larval, nymphal, and adult life stages. A Bayesian multivariate modelling framework was used to examine seasonal patterns, habitat effects, spatial variation, and biological links between life stages. Two …

Left In The (Road) Dust: Analyzing Advanced Clean Cars Ii In California’S Disadvantaged Communities, Jj Hoffman

Pomona Senior Theses

Across the United States, air pollution disproportionately impacts minority groups. California’s Advanced Clean Cars II (ACC II) waiver was positioned to lead to significant environmental justice impacts, such as reductions in emissions and adverse health outcomes, by establishing stricter regulations for vehicle emissions and ensuring that 100 percent of new passenger vehicle sales are zero-emission by 2035. As the federal government recently nullified ACC II, pollution, and by extension health, could worsen, especially in disadvantaged communities. The thesis established several important relationships, including how disadvantaged communities experienced higher traffic, pollution, and worse health outcomes than non-disadvantaged communities. Though the results …

Feral Horses And Native Ungulates: Evaluating The Potential For Competition In Predator–Prey Communities Of Alberta’S Upper Foothills, Birch Gano

Graduate Student Theses, Dissertations, & Professional Papers

Feral herbivores are expanding in range and numbers globally, yet their community-level effects in ecosystems are poorly resolved. We evaluated whether feral horses reshape predator–prey–vegetation dynamics in Alberta’s Upper Foothills, Canada, through two pathways; i) potential exploitative competition for forage and ii) apparent competition via shared predators. We combined fecal DNA metabarcoding with remote wildlife cameras to quantify diets, spatiotemporal co-occurrence, and the role of horses in carnivore diet. We analyzed 241 ungulate scats (feral horses, elk, bighorn sheep, cattle, moose, and deer), 96 combined camera-years at 23 sites, and 190 carnivore scats (wolves, cougars, coyotes, bears) from 2023–2025. The …

High Algal Biomass Is Decoupled From Metabolism In The Gallatin River, Cora Mae Steinbach

Graduate Student Theses, Dissertations, & Professional Papers

Assessing eutrophication in rivers is difficult compared to lakes and coastal waters, because most algal biomass occurs on the riverbed and flows interact and co-vary with production (Biggs and Close, 1989; Bernhardt et al., 2018). Riverine eutrophication is typically assessed using algal biomass and water column nutrients (U.S. Environmental Protection Agency, 2000), but biomass is highly variable and labor-intensive to measure, while nutrient concentrations often underestimate enrichment due to rapid biological uptake (Dodds and Smith, 2016). Reach-scale river metabolism can help evaluate long-term functional change in rivers recovering from nutrient enrichment (Arroita et al., 2019; Jankowski et al., 2021; Diamond …

An Ecological-Evolutionary Investigation Of Phenotypic, Genetic, And Environmental Variation And Correlations Among Reproductive Traits Of Tall Goldenrod (Solidago Altissima), Michael J. Wise, Daniel Lavy, David E. Carr, Warren G. Abrahamson Ii

Faculty Journal Articles

Although fitness-related traits are expected to be under strong selection, traits related to reproduction are often quite variable within plant populations. We used data from two large greenhouse experiments to quantify phenotypic, genetic, and environmental variation, as well as genetic tradeoffs that might help explain the maintenance of withinpopulation variation in four traits related to sexual or vegetative reproduction in tall goldenrod (Solidago altissima). The goldenrod population exhibited high levels of both phenotypic and genetic variation for capitulum (flower head) number and size, seed production, and rhizome growth. Significant negative genetic correlations were present between the number of capitula and …

Frame: Fast Reference-Based Ancestry Makeup Estimation Tool, Pramesh Shakya, Ardalan Naseri, Degui Zhi, Shaojie Zhang

Faculty, Staff and Student Publications

Motivation: The availability of large-scale genetic data presents a unique opportunity to study the genetic ancestries of individuals, which requires an efficient and scalable method. The existing global ancestry methods are accurate, but they cannot scale to large genetic datasets. Identity-by-descent (IBD) segments are DNA segments shared by individuals such that they are inherited from a common recent ancestor without recombination. These IBD segments, which reflect co-ancestry, provide an efficient alternative for inferring genetic ancestry.

Results: We introduced a reference-based global ancestry inference method called FRAME (Fast Reference-based Ancestry Makeup Estimation). FRAME utilizes partial local ancestry information estimated through IBD …

An Ensemble Classifier For Ordinal Outcomes In High-Dimensional Genomics Data, Heranga K. Rathnasekara, Sinjini Sikdar

Mathematics & Statistics Faculty Publications

Analysis of genomics data for predicting disease outcomes is a fast-growing field in medical research. There often exist categorical, specifically, ordinal outcomes that need to be predicted based on genomic profiles. This has led to recent development of some high-dimensional ordinal classification methods that can address the large dimensionality of the genomic covariate set. These high-dimensional ordinal models tend to vary widely in their performance depending on the data they are applied to and the evaluation criteria used. In this article, we outline an ensemble ordinal classifier that integrates different ordinal modeling approaches through bootstrap-based model evaluation, multi-metric performance assessment, …

Evaluating Species At Risk In Data-Limited Fisheries: A Productivity-Susceptibility Analysis For Marine Aquarium Fish, Gabrielle A. Baillargeon, Alice A. Wynn, Jemelyn Grace P. Baldisimo, Michael F. Tlusty, Andrew L. Rhyne

Biological Sciences Faculty Publications

The marine aquarium trade (MAT) is a significant global industry harvesting millions of wild-caught, live coral reef fishes for public and private aquaria markets in the United States and Europe annually, while supporting fisher livelihoods in the Indo-Pacific. This diverse and species-rich trade is considered data-limited, creating barriers to quantifying the current and future socio-ecological sustainability of the fishery. We present a revised and expanded productivity–susceptibility analysis (PSA) that serves as a holistic risk assessment to estimate the vulnerability of marine aquarium fish to overfishing. Our global analysis includes 306 species that are actively in trade. Improvements to the PSA …
