Soil Microbial Responses To Artifical Light At Night, Randall L. Walker May 2026

Soil Microbial Responses To Artifical Light At Night, Randall L. Walker

Open Access Theses & Dissertations

Global change, driven by both natural processes and human activities, has significantly transformed ecosystems. Urbanization and artificial light at night (ALAN) are key contributors, disrupting natural light cycles and influencing biological rhythms, biodiversity, and ecosystem functions. Thus far, there remains a gap in knowledge of how soil ecosystems are impacted by ALAN. This study uses a laboratory incubation to investigate the effects of ALAN on soil microbial communities and functions across urban and natural ecosystems. Briefly, soil was collected from eight sites around El Paso, Texas and neighboring New Mexico representing urban and rural light exposure. Soil was then subjected …

Optimized Ultrasound Imaging Of Phase-Change Nanodroplets, Charles R Dyall, Dmitry Nevozhay, Andy Liu, Trevor M Mitcham, George J Lu, Konstantin V Sokolov, Richard R Bouchard

Faculty, Staff and Student Publications

Phase-change nanodroplets (PCNDs) continue to generate significant research interest due to their potential to extravasate into tissue, to be targeted for molecular imaging and drug delivery, and to undergo an induced phase-change to "activated" microbubbles (MBs) for ultrasound (US) imaging. To accurately quantify molecular markers, however, one assumes a consistent proportion of PCNDs in a region of interest (ROI) are stably activated and imaged. Herein we present a framework for developing a diagnostic sequence that is optimized for PCND activation uniformity, contrast, and acquisition time. To develop this framework, activation was examined at three scales of increasing complexity: single, adjacent, …


Degradation And Metabolic Analysis Of Synthesized Quorum-Sensing Signals By The Model Eukaryote Chlamydomonas Reinhardtii, Adam Josef Bach May 2026

Degradation And Metabolic Analysis Of Synthesized Quorum-Sensing Signals By The Model Eukaryote Chlamydomonas Reinhardtii, Adam Josef Bach

Theses and Dissertations

Bacterial organisms can “talk” with one another on a colony-wide scale using a communication system known as quorum-sensing (QS) via chemical signals. These signals are produced at a basal rate throughout the life of the bacteria and are classified as autoinducers, which diffuse across the cell membrane. Once the critical concentration is reached, they begin to diffuse back into the cell and initiate a phenotypic change. As these signals exist outside the membrane of their producer, they are also accessible to other organisms. It has already been noted that some plant species uptake these compounds through their roots and break …

Wildland Resources Faculty Publications

Warming, sea-level rise, and changing herbivory patterns are affecting ecosystem processes in northern coastal soils, including carbon and nitrogen cycling, although their combined effects are poorly understood. We studied the impact of these changes in a full-factorial microcosm experiment using four distinct soil types from the Yukon-Kuskokwim Delta of western Alaska. Soil was collected from three coastal wetlands, which differ in flooding frequency and use by migratory geese, and one rarely-flooded upland tundra used by geese in late summer. Microcosms containing these soils were incubated for 16 weeks at 10°C or 18°C, with or without three short-term floods, and with …


Investigating The Synthesis And Antibacterial Activity Of A Main-Chain Cationic Polymer, Emily Smith Apr 2026

Investigating The Synthesis And Antibacterial Activity Of A Main-Chain Cationic Polymer, Emily Smith

Honors Theses

Antibiotic resistance is a growing threat to public health. Due to the overuse of antibiotics in agriculture, the overprescription of antibiotics, and the misuse of antibiotics by patients, antibiotic resistance is spreading at an alarming rate. As antibiotic resistance spreads, the antibiotics we depend on to treat common infections become ineffective. Therefore, it is imperative to develop novel treatments for infections that do not increase the prevalence of antibiotic resistance. One treatment being explored is the use of synthetic polymers with antibacterial properties. Synthetic polymers are advantageous because they can be synthesized from widely available precursors and their structure is …


Sex Or Survival: Does Wounding Elicit A Somatic Reproductive Tradeoff In Narnia Femorata Males?, Lillian E. Burbulis Apr 2026

Sex Or Survival: Does Wounding Elicit A Somatic Reproductive Tradeoff In Narnia Femorata Males?, Lillian E. Burbulis

Departmental Honors & Graduate Capstone Projects

Animals must partition resources into different life history traits resulting in tradeoffs because resources are finite. A tradeoff is the allocation of resources to one trait over another. Theory states that energy is allocated in a hierarchical fashion. For example, somatic maintenance should be a higher priority than reproduction, resulting in more resources being allocated to somatic maintenance compared to reproductive traits. The metabolic investment hypothesis states that energy must follow a hierarchical order prioritizing somatic maintenance over reproduction. Another hypothesis for energy allocation is the terminal investment hypothesis. This hypothesis states that energy will be allocated to reproduction over …

Mapping Mgmt Methylation Sites That May Predict Chemotherapy Success In Glioblastoma, Kennedy Bueno Apr 2026

Mapping Mgmt Methylation Sites That May Predict Chemotherapy Success In Glioblastoma, Kennedy Bueno

Celebrating Scholarship and Creativity Day (2018-)

Glioblastoma is the most common malignant primary brain tumor in adults, with a median survival of 15 months post-diagnosis. Resistance to standard temozolomide (TMZ) chemotherapy is common and is strongly influenced by O6-methylguanine-DNA methyltransferase (MGMT), a DNA repair enzyme that reverses TMZ induced DNA damage. Reduced MGMT expression is associated with greater TMZ sensitivity and improved survival. Although MGMT promoter cytosine-phosphate-guanine dinucleotide (CpG) methylation is linked to treatment response, the individual CpG sites responsible for MGMT silencing remain unclear. This research aims to identify which sites are necessary to suppress MGMT expression and increase TMZ sensitivity. This project will map …


Creating A Unique Hemoglobin-Based Oxygen Carrier, Clayton Fuller Apr 2026

Creating A Unique Hemoglobin-Based Oxygen Carrier, Clayton Fuller

Celebrating Scholarship and Creativity Day (2018-)

The purpose of this thesis is to explain the current state of alternative oxygen carriers and propose a new hemoglobin-based oxygen carrier (HBOC) as a blood substitute/ blood therapeutic. Blood donation has drawbacks: risk of spread of infection, short storage time, and blood typing, and the current shortage. There are several possible modifications for hemoglobin to create a carrier (HBOC) which address specific issues related to allowing free hemoglobin to exist extra cellularly. One issue to address is vasoconstriction caused by nitric oxide scavenging, which has been solved by increasing the molecular weight of the HBOC via (co)polymerization, or by …

Mitigating agricultural nutrient runoff and improving water quality are key challenges in meeting food and energy demands. To address this challenge, short rotation woody crops (SRWC), specifically Populus deltoides (eastern cottonwood) and its genotypes, can be planted at the interface of riparian areas and agricultural production fields to alleviate fertilizer runoff into adjacent bodies of water. This research employed an experimental design to evaluate the effects of P. deltoides diversity on tree productivity and nutrient uptake, and how it mitigates agricultural runoff. Ion exchange resins were deployed 0.5 meters below the soil surface at three different sites in Mississippi, each …


Beyond Beneficial Margins: Four Mechanisms Linking Border Vegetation To Pest Dynamics, Jorge F. M. Cardoso, Fabiane M. Mundim Apr 2026

Beyond Beneficial Margins: Four Mechanisms Linking Border Vegetation To Pest Dynamics, Jorge F. M. Cardoso, Fabiane M. Mundim

Biology Student Research

Vegetated field borders are widely promoted as tools to enhance biodiversity and strengthen biological control in agroecosystems. However, their role in pest dynamics remains conceptually fragmented and empirically inconsistent. Here, we develop a unified framework explaining how crop border vegetation influences pest populations through four interlinked ecological mechanisms. First, borders act as host reservoirs and selective filters, providing alternative hosts and overwintering habitat that enhance pest persistence across crop cycles. Second, borders modify pest colonization dynamics by shaping movement, aggregation, and host-location behavior at crop edges. Third, borders restructure multitrophic networks, simultaneously supporting natural enemies, alternative prey, vectors, and pathogens, …

Breeding For Diverse Color And Protein Quality In Popcorn And Sweet Corn, Jonathan Niyorukundo Apr 2026

Breeding For Diverse Color And Protein Quality In Popcorn And Sweet Corn, Jonathan Niyorukundo

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Sweet corn and popcorn are important crops consumed globally as vegetable and snack, respectively. They are deemed healthy foods due to high fiber and carotenoid contents, especially in yellow varieties. Commercial varieties are optimized for high-yielding agronomics, and previous efforts were made to improve specific macro- and micronutrient contents. Both sweet corn and popcorn have poor protein quality due to the inadequate essential amino acids such as lysine and tryptophan. Moreover, commercial varieties are predominantly yellow, thereby offering no diversity of other maize colors, which are potentially healthier and more appealing to the consumer. In this project, we sought to …

Evaluating Inner-Tainment With A Ghetto Perspective For Positive Thought Adjustment In Ghetto Communities, Shontae L. Graham

Doctoral Dissertations and Projects

Environmental challenges and disadvantages impact cognitive scripts and develop persistent frustration. Frustration is both mental and physical and can be negative or positive. It evokes emotion, which is prompted by memory and its associated level of importance. The integration of emotion, memory, and imagination can set the stage and create an act to transition negative frustration and align past experiences with new perspectives. This study used a qualitative Interpretive Phenomenological Analysis approach to investigate the use of self-scripted enactment as a self-help technique for positive thought adjustment. The technique is called Inner-tainment and was used to determine if there were …

Soft Systems For Community-Based Hcv Management In Indonesian Oil Palm Plantations, Neny Indriyana, Suyud Warno Utomo, Tri Edhi Budhi Soesilo, Linda Darmajanti

Journal of Environmental Science and Sustainable Development

Certification mandates under the Roundtable on Sustainable Palm Oil (RSPO) and Indonesian Sustainable Palm Oil (ISPO) have made measurable strides in promoting sustainability standards, yet governance challenges in High Conservation Value (HCV) 4, 5, and 6 management remain insufficiently addressed within Indonesian plantation contexts.  Drawing on adaptive governance theory and the social-ecological systems framework, this study argues that such gaps are structurally linked to the marginalisation of community agency within corporate-dominated decision-making. This study proposes and empirically evaluates an integrated governance framework that positions community engagement as a functional contributor to conservation outcomes within plantation landscapes of West Kalimantan, under …


Using The Flexon Approach To Rnai To Identify Essential Genes That Affect Gonadal Development In C. Elegans, Joyce S. Lefevers Apr 2026

Using The Flexon Approach To Rnai To Identify Essential Genes That Affect Gonadal Development In C. Elegans, Joyce S. Lefevers

Undergraduate Theses

To elucidate the molecular role of essential genes in the gonadal development of Caenorhabditis elegans (C. elegans) it is necessary to utilize specialized molecular techniques such that the phenotypic effects of gene knockdown can be studied while the viability of the organism is preserved. Shaffer and Greenwald (2022) developed the floxed exon (flexon), a tool that improves upon previous approaches to spatiotemporal control of gene expression. The flexon subunit is made up of an artificial exon with a stop cassette flanked by artificial introns which, when inserted into a gene of interest, prevents the expression of that gene. …

Highly Oxidation-Resistant Imidazolium-Modified Catechol For Stable Wet Adhesion Under Alkaline Conditions, Kan Wang, Yue Xu, Fatemeh Razaviamri, Chunling Zhang, Zhihui Zhang, Bo Liu, Bruce P Lee

Michigan Tech Publications

Premature oxidation of catechol drastically reduces its adhesion strength and utility. This study chemically linked catechol to an imidazolium group, which functioned as an intrinsic protecting group that retarded catechol oxidation and enabled stable wet adhesion under basic conditions. Johnson–Kendall–Roberts (JKR) contact mechanical testing was performed to determine the work of adhesion (Wadh) of imidazolium-modified catechol (VIMCAT), which remained unchanged for up to 48 hours when incubated at pH 7.4. Contrastingly, Wadh values of unprotected catechol were quickly reduced by over 25% within 30 minutes. VIMCAT still retained its initial adhesion strength even after incubation at pH …
