Citizen Science Helps Monitor Urban Biodiversity: An Interactive, Data-Driven, And Open-Source Perspective, Katie Slack
Geography ETDs
Story maps, a powerful tool for communicating environmental narratives, are often commercial and lack many interactive functions. We integrate a data-driven and interactive geovisualization within an open-source story map created from high-attribute citizen science datasets. This story map creates a backend programming infrastructure for accessible, open-source science communication tools. Our story map intuitively communicates the findings from our web map application (app) portion of the story map to the public and helps reveal findings from the iNaturalist datasets. Albuquerque, New Mexico, United States is a demonstrative case study, but our tools can be flexibly adapted to other cities. Geovisualizations revealed …

The steroid hormone testosterone is important for stimulating male reproductive processes including territory acquisition, mating displays, and spermatogenesis. When examining the relative effects of testosterone on reproductive processes, it is most reasonable to focus on peak baseline testosterone levels, especially for reproductive processes that may occur during specific times of day, such as mating and spermatogenesis. However, some studies have not found consistent positive relationships between circulating testosterone levels and reproductive variables. These nonsignificant relationships could be driven by methodology, as most studies in wild, free-living animals collect blood samples during an animals' active period, yet many species show peak …

Biology Faculty Publications
Background: Helicobacter pylori infects approximately half of the global population, leading to gastric and duodenal ulcers. Despite the availability of antibiotics, challenges such as patient reluctance, high treatment costs, and antibiotic resistance limit their effectiveness, making vaccination a promising alternative. This study used immunoinformatics to identify candidate epitopes for a multiepitope vaccine construct against H. pylori.
Material and methods: The protein variability server was utilized for conservation analysis. The epitopes were screened for antigenicity, allergenicity, toxicity, cross-reactivity, and population coverage. Selected epitopes were docked with their corresponding human leukocyte antigen (HLA) alleles, and thermodynamic quantities were determined. Five virulence …

Toward Simulating 2d Cell Surfaces In A Disk, Myriam Allred
Toward Simulating 2d Cell Surfaces In A Disk, Myriam Allred
Mathematics & Statistics ETDs
Certain evolution models of cell surfaces (treated in two-dimensions) involve the solution of the Helmholtz equation with jump conditions enforced on an immersed closed curve. This thesis presents a sparse, modal spectral method for solving such Helmholtz problems. The solution is required to be continuous across the curve, but with a jump discontinuity in the normal derivative proportional to the planar curvature. The method relies on classical Fourier-Chebyshev basis functions, with the application of modal Chebyshev integration matrices to achieve sparse, banded approximations of the Helmholtz equation. The method achieves spectral convergence, despite the inherent low regularity of the relevant …
Assessing The Ecological Drivers And Consequences Of Partial Migration In Hudson River Striped Bass Over Three Decades, Caitlin Egan Zimmer
Assessing The Ecological Drivers And Consequences Of Partial Migration In Hudson River Striped Bass Over Three Decades, Caitlin Egan Zimmer
Biology ETDs
Climate change and shifts in human land use have caused extensive impacts to the connectivity, structure, and resilience of aquatic populations. Partial migration (PM), where only some individuals from a population migrate while the rest remain resident, can mitigate population-level responses to environmental stressors. However, little is known of the underlying mechanisms promoting variation in migration and whether these shift over time. In the Hudson River Estuary, striped bass (Morone saxatilis) are known to exhibit anadromous PM behavior. Here, I measured carbon isotopes (δ13C) of essential amino acids in striped bass scales to determine variation in …
Plant Reproductive Strategies Shift In Response To Restoration Using Beaver Dam Analogs, Laurel F. Martinez
Plant Reproductive Strategies Shift In Response To Restoration Using Beaver Dam Analogs, Laurel F. Martinez
Biology ETDs
As riparian communities become increasingly degraded, restoration treatments are being implemented in streams to recover ecosystem functions. In the Jemez Mountains, beaver dam analogs (BDAs) are used to restore degraded streams by connecting the floodplain and increasing the extent of anoxic soil conditions. These environmental disturbances are expected to alter how riparian plants recruit, particularly their allocation to seed-based and vegetative regeneration strategies. We investigated whether BDAs and associated changes in soil water filled pore space (WFPS) affected riparian plant recruitment. We investigated the number of flowering stems as a proxy for seed-based regeneration and rhizome length and mass as …
Ecoimmunology Of Dirty Physella Acuta Snails, Kevin Arthur Mcquirk
Ecoimmunology Of Dirty Physella Acuta Snails, Kevin Arthur Mcquirk
Biology ETDs
Research on Physella acuta, an invasive freshwater snail, reveals insights into its parasitology, fitness, and molecular biology. Morphological and molecular analyses revealed two distinct mitogenomic lineages, local (B) and invasive (A) strains of native P. acuta, both having comparable trematode infection rates, suggesting that the low infection rates observed from A in invaded regions result from "enemy release" rather than immune incompatibility. Fitness assessments showed that while lineages A and B performed similarly under laboratory conditions, rewilding experiments revealed significantly higher fitness in lineage A. Transcriptomic profiling supported these differences, with A snails showing greater immune-related gene expression and …

Spatial Ecology And Habitat Selection Of Eastern Pinesnakes: Case Study On The Importance Of Scale In Conservation Biology, Matthew Grisnik, Alan Jones, Rachel Brubaker, Andrew M. Grosse, Scott L. Parker
Biology
Species are in decline world-wide, driven by multiple factors including habitat fragmentation. Understanding the habitat selection processes of species in these fragmented landscapes has become a focus of ecological studies and is a major component of conservation plan development. However, understanding how landscape level processes influence patterns of habitat selection is often ignored. Here we assessed the influence of landscape level processes in the habitat selection of Eastern Pinesnakes, a species in decline, within a protected area in South Carolina, USA. Over the course of a year, we tracked 8 Eastern Pinesnakes within a small protected area. Snakes exhibited seasonal …

Using Triple Oxygen Isotopes To Investigate Water Usage In Desert Ecosystems, Cloe V. Knutson
Earth and Planetary Sciences ETDs
In arid environments, maintaining water balance can be more critical for survival than obtaining food. As droughts intensify, understanding how animals manage body water is essential. Triple oxygen isotope analysis provides a novel way to trace water sources in animals, distinguishing contributions from free water, food-derived oxygen, and atmospheric O2. We developed an equilibration method using CO2–H2O oxygen exchange and measured δ’18O and Δ’17O values via tunable infrared laser direct spectroscopy (TILDAS). Validated against traditional fluorination methods, this technique enables streamlined analysis of whole blood and plant samples. Applied to …

Environmental causes of intrauterine growth restriction (IUGR) remain poorly characterized. Here, we compare germ-free (GF) and conventionally raised (CONV-R) mice to assess the effects of the gut microbiota on placental/fetal development at embryonic day (E)11.5 (end of placentation) and E17.5 (near term). Pregnancy- and microbiota-associated changes in gene expression occur along the gut, including those related to angiogenesis, while bacterial composition and fermentation activity remain stable. Placental weights at E11.5 and fetal weights at E17.5 are significantly reduced in GF animals. Compared to CONV-R dams, the GF maternal decidua exhibits similar vascular histomorphometric features at E11.5 and E17.5, and numbers …

Microneedle-Based Lc-Ms/Ms Profiling Of Dermal Interstitial Fluid Reveals Early Lipid Dysregulation Contributing To Painful Neuropathy In Prediabetic And Type 2 Diabetic Rats, Srinivasa Rao Gadam
Biomedical Sciences ETDs
Painful diabetic neuropathy (PDN), a complication of type 1 and type 2 diabetes, also occurs in obesity and prediabetes, with dyslipidemia as a modifiable risk factor. The distal-to-proximal neuropathy pattern and length-dependent intraepidermal nerve fiber loss suggest peripheral contributions. We hypothesized that elevated neurotoxic lipid intermediates—diacylglycerols (DAG), free fatty acids (FFA), and acylcarnitines (CARs)—in the dermal interstitial fluid (ISF) drive metabolism-associated hyperalgesia in prediabetic and diabetic rats. Using a microneedle array (MIA) with LC-MS/MS, we profiled ISF and serum lipids from high-fat diet (HFD) and HFD + streptozotocin (STZ) rat models alongside Hargreaves testing. ISF lipid changes appeared earlier (weeks …

Immune Regulation In Fungal Airway Inflammation And Host Defense, Ruoning Wang
Immune Regulation In Fungal Airway Inflammation And Host Defense, Ruoning Wang
Biomedical Sciences ETDs
Asthma is a chronic inflammatory disease of the lungs characterized by complex pathophysiological mechanisms and diverse endotypes, primarily categorized as T helper type 2 cell (Th2)-high and Th2-low asthma. Despite significant advances in understanding asthma pathogenesis, the mechanisms governing the pulmonary immune system’s response to external challenges have not been fully understood. To address these gaps, this comprehensive project was designed to investigate the interplay between fungal infections and specific CD4+ T cell populations in asthma. Our findings suggest that fungal infections can contribute to neutrophilic asthma by promoting the migration of platelet-myeloid aggregates into the lungs. We also …

Organic acids, as natural metabolites, play crucial roles in human metabolism and health. Tumor Necrosis Factor (TNF), a pivotal mediator in immune regulation and inflammation, is a key therapeutic target. We evaluated ten organic acids as TNF modulators using in silico molecular docking, followed by detailed ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) profiling and molecular dynamics (MD) simulations for three lead candidates: gallic, aconitic, and crocetin acids. Their effects on TNF gene expression were then assessed in vivo using a mouse leukocyte model. The in silico results indicated that crocetin had the highest TNF binding affinity (−5.6 to −4.6 …
Interdependence And Place In Mescalero Homelands, 1660-1865, Joseph A. Ukockis
Interdependence And Place In Mescalero Homelands, 1660-1865, Joseph A. Ukockis
History ETDs
This dissertation examines strategic relationships that Mescalero Apaches made among themselves and with non-Mescalero communities from 1660 to 1865. It references Mescalero place names in piecing together pertinent stories across their vast ancestral homelands, demonstrating regional continuities in social, political, and economic dynamics over two centuries. It argues that bonds of interdependence, rather than armed resistance, were critical in maintaining autonomy and the ability to move freely, conduct effective diplomacy to protect claims to homelands, access resources in times of scarcity, and form key alliances that presented possibilities for resistance to colonial domination. Central to these dynamics were Mescalero and …
Assessing The Effects Of Antibiotic Selectivity And Temperature On The Antimicrobial Activity Of Isolates Derived From The Deep-Sea Sponge Pheronema Capenteri, Lex L. Hilario
The Plymouth Student Scientist
The rapid increase of antibiotic resistance necessitates the discovery of novel antibiotic compounds capable to tackle these resistant bacteria. Deep-sea sponges accommodate a diverse and dense microbiome filled with an array of bacterial communities that have the potential to produce novel antimicrobials. Some discovered novel strains have already shown their capability in producing secondary metabolites that are effective against clinically relevant strains. This study aims to evaluate the impacts of different culture conditions; antibiotic selectivity and temperature, on the antimicrobial activity of isolates recovered from three different Pheronema carpenteri deep-sea sponges. Using culture-dependant methods, a total of 59 bacterial isolates …

Despite the success of targeted inhibitors in cutaneous melanoma, therapeutic responses are limited by the aged tumor microenvironment and drug-tolerant residual cells. Given the similarities between drug tolerance and cellular dormancy, we studied the dormancy marker, nuclear receptor subfamily 2 group F member 1 (NR2F1), in response to BRAF-V600E inhibitors (BRAFi) plus MEK inhibitors (MEKi) in BRAF-mutant melanoma models. Transcriptomic analysis of melanoma patient samples treated with BRAFi + MEKi showed increased NR2F1. NR2F1 was highly expressed in the drug-tolerant invasive cell state of minimal residual disease in patient-derived and mouse-derived xenografts on BRAFi + MEKi. NR2F1 over-expression was sufficient …

The adaptive immune response is a complex defense mechanism that develops over time to recognize and eliminate pathogens with remarkable precision and durability. This dissertation investigates the dynamics, scaling, and efficiency of the adaptive immune response through a synthesis of computational modeling, mathematical analysis, and agent-based simulations. First, we analyze the topology of the lymphatic network and investigate the T cell search time to find the lymph node that is containing the matching dendritic cell. Second we show how the scaling of lymph node number and volume with body mass, leads to scale-invariant search times for T cells locating antigen-bearing …

Neutrophils play a key role in autoimmune diseases like rheumatoid arthritis, contributing to tissue damage through rapid recruitment and activation. In this study, we investigated the regulatory properties of two receptor-like tyrosine phosphatases (RPTPs), CD45 and CD148, in inflammatory arthritis. Using an in vivo mouse model of K/BxN serum transfer-induced arthritis, we found that CD45 and CD148 feature distinct regulatory properties during inflammatory arthritis. CD45 is required for neutrophil infiltration, cytokine release, and reactive oxygen species production, whereas CD148 deficiency leads to a delayed onset of arthritis but unaltered overall neutrophil infiltration and reduced ROS production. Furthermore, we could demonstrate …

Glucose metabolism is a pivotal hub for cellular energy production and the generation of building blocks that support cell growth, survival, and differentiation. Cancer cells undergo metabolic reprogramming to sustain rapid proliferation, survive in harsh microenvironments, and resist therapies. Beyond producing energy and building blocks to meet cancer cell demands, glucose metabolism generates numerous metabolites that serve as signaling molecules, orchestrating signaling pathways and epigenetic modifications that regulate cancer cell phenotypes and immunity. In this review, we discuss how glucose, through its metabolism and direct actions, influences diverse biological processes driving cancer progression and therapeutic resistance, while also exploring metabolic …

The accumulation of abnormal, non-mutated tau protein is a key pathological hallmark of Alzheimer's disease (AD). Despite its strong association with disease progression, the mechanisms by which tau drives neurodegeneration in the brain remain poorly understood. Here, we selectively expressed non-mutated or mutated human microtubule-associated protein tau (hMAPT) in neurons across the mouse brain and observed neurodegeneration in the hippocampus, especially associated with non-mutated human tau. Single-nuclei RNA sequencing confirmed a selective loss of hippocampal excitatory neurons by the wild-type tau and revealed the upregulation of neurodegeneration-related pathways in the affected populations. The accumulation of phosphorylated tau was accompanied by …
