Improving Wetland Revegetation In The Intermountain West: Wetland Manager And Native Plant Vendor Insights And Challenges, Annie L. Henry, Rae Robinson, Kate Sinnott, Mark W. Brunson, Emily E. Tarsa, Adrienne Ernst, Karin M. Kettenring

All Current Publications

Diverse native vegetation supports the many ecosystem services that wetlands provide to society. In degraded wetlands, the native vegetation often needs to be reseeded or replanted as part of the restoration process. However, such wetland revegetation practices of managers are relatively undocumented and the availability of native plants for wetland restoration from vendors has been unclear. We conducted surveys of wetland managers and wetland native plant vendors in the Intermountain West in 2023 to understand their practices, challenges, and perspectives. We found that wetland managers in the Intermountain West revegetate diverse habitats for important ecosystem services despite very limited budgets …


Barriers And Breakthroughs In The Evolution Of Aggregative Multicellularity, Israt Jahan Mar 2025

Barriers And Breakthroughs In The Evolution Of Aggregative Multicellularity, Israt Jahan

Arts & Sciences Graduate Student Theses and Dissertations

The evolution of multicellular organization represents a key innovation in the history of life, yet fundamental questions remain about the evolutionary mechanisms that allowed some lineages to achieve remarkable complexity, while constrained others in their elaboration. The widely accepted single-cell bottleneck model provides a compelling explanation for the success of clonal multicellularity by reducing internal conflict and facilitating developmental integration. However, this perspective does not fully account for the stability and repeated evolution of aggregative multicellularity, where cooperation emerges among previously independent cells that may not be genetic relatives. Aggregative multicellularity demonstrates that the evolution of multicellularity is not a …

Clostridium perfringens is a prevalent gut bacterial pathogen in humans and animals. This study investigated the role of the mechanistic targets of rapamycin (mTOR) and deoxycholic acid (DCA) on C. perfringens intestinal infection. Chickens were sequentially infected with Eimeria maxima and received the mTOR inhibitor rapamycin and DCA. C. perfringens-induced necrotic enteritis (NE) was evaluated using body weight gain (BWG), histopathology, bile acids, pathogen colonization, cell infiltration and death, and gene expression. The significant difference of p < 0.05 was analyzed by one-way ANOVA and multiple comparisons. Notably, rapamycin strongly reduced the subclinical and clinical NE histopathologies. DCA and DCA combined with rapamycin alleviated clinical NE and BWG loss. Rapamycin, DCA, and DCA + rapamycin attenuated bile acid reduction in NE birds, and they also reduced immune cell infiltration into the intestinal lamina propria as well as immune cell migration in vitro. At molecular levels, DCA and DCA + rapamycin reduced proinflammatory IFN gamma, MMP9, IL23, and IL17 gene expression. Rapamycin, DCA, and DCA + rapamycin reduced NE-induced intestinal cell apoptosis. Together, these results suggest that mTOR signaling mediates C. perfringens-induced ileitis, and combining mTOR inhibition and DCA improves the intervention efficacy against NE ileitis and BWG loss.

School of Medicine Publications

Bipolar disorder is a leading contributor to the global burden of disease1. Despite high heritability (60–80%), the majority of the underlying genetic determinants remain unknown2. We analysed data from participants of European, East Asian, African American and Latino ancestries (n = 158,036 cases with bipolar disorder, 2.8 million controls), combining clinical, community and self-reported samples. We identified 298 genome-wide significant loci in the multi-ancestry meta-analysis, a fourfold increase over previous findings3, and identified an ancestry-specific association in the East Asian cohort. Integrating results from fine-mapping and other variant-to-gene mapping approaches identified 36 credible genes …

Murine Studies On Ketogenic Modulation Of Metabolism And Epigenetics In Olfaction- Based Learning, Lps Inflammatory Response, And Sex Dimorphisms In Dietary Response, Sara E. H. Moss Mar 2025

Murine Studies On Ketogenic Modulation Of Metabolism And Epigenetics In Olfaction- Based Learning, Lps Inflammatory Response, And Sex Dimorphisms In Dietary Response, Sara E. H. Moss

USF Tampa Graduate Theses and Dissertations

Ketogenic diets are well-established therapeutic interventions for epilepsy, with documented neuroprotective effects arising from their metabolic, antioxidant and anti-inflammatory properties. Beyond epilepsy, ketogenic therapies are under investigation for various conditions including Alzheimer disease, cancer, diabetes, and cardiovascular disease. These diets suppress insulin levels and shift metabolic physiology toward fat and ketone body metabolism. This elevates circulating levels of ketone bodies, namely beta-hydroxybutyrate, acetoacetate, and acetone, which serve as both energy substrates and signaling molecules. The state of elevated ketone bodies (ketosis) can be achieved with various formulations of a ketogenic diet as well as exogenous ketone supplementation, though the signaling …

Domain Communication In Bifunctional Proline Utilization A From Sinorhizobium Meliloti, Emma Bitterman

Honors Program: Senior Projects (Public)

The reduction potential of flavin bound to Sinorhizobium meliloti proline utilization A (SmPutA) is beneficial in providing vital information on enzyme activity and the active site environment. Flavin is crucial in biological metabolism such as aerobic respiration and other important processes like oxygen activation that are catalyzed by flavin-dependent enzymes. (4). In this study, we seek to determine whether the redox potential of SmPutA-bound flavin can be used to characterize potential long-distance communication and analyze the possibilities of inactivation reversibility. SmPutA is a large bifunctional enzyme that catalyzes the overall oxidation of proline to glutamate via two catalytic domains (1). …

Faculty, Staff and Student Publications

Adoptive cell therapy (ACT) can address an unmet clinical need for patients with relapsed/refractory acute myeloid leukemia (AML), but its effect is often modest in the setting of high tumor burden. In this study, we postulated that strategies to lower the AML apoptotic threshold will augment T cell killing of AML cells. BH3 mimetics, such as venetoclax, are a clinically approved class of compounds that predispose cells to intrinsic apoptosis by inhibiting anti-apoptotic mitochondrial proteins. We explored the anti-leukemic efficacy of BH3 mimetics combined with WT1-specific CD8+ T cells on AML cell lines and primary samples from patients with a …


Machine Learning Shows A Limit To Rain-Snow Partitioning Accuracy When Using Near-Surface Meteorology, Keith S. Jennings, Meghan Collins, Benjamin J. Hatchett, Anne Heggli, Nayoung Hur, Sonia Tonino, Anne W. Nolin, Guo Yu, Wei Zhang, Monica M. Arienzo Mar 2025

Plants, Soils, and Climate Faculty Publications

Partitioning precipitation into rain and snow with near-surface meteorology is a well-known challenge. However, whether a limit exists to its potential performance remains unknown. Here, we evaluate this possibility by applying a set of benchmark precipitation phase partitioning methods plus three machine learning (ML) models (an artificial neural network, random forest, and XGBoost) to two independent datasets: 38.5 thousand crowdsourced observations and 17.8 million synoptic meteorology reports. The ML methods provide negligible improvements over the best benchmarks, increasing accuracy only by up to 0.6% and reducing rain and snow biases by up to -4.7%. ML methods fail to identify mixed …


The Tumor Microenvironment Is An Ecosystem Sustained By Metabolic Interactions, Emily Jane Kay, Sara Zanivan Mar 2025

The Tumor Microenvironment Is An Ecosystem Sustained By Metabolic Interactions, Emily Jane Kay, Sara Zanivan

Faculty, Staff and Student Publications

Cancer-associated fibroblasts (CAFs) and immune cells make up two major components of the tumor microenvironment (TME), contributing to an ecosystem that can either support or restrain cancer progression. Metabolism is a key regulator of the TME, providing a means for cells to communicate with and influence each other, modulating tumor progression and anti-tumor immunity. Cells of the TME can metabolically interact directly through metabolite secretion and consumption or by influencing other aspects of the TME that, in turn, stimulate metabolic rewiring in target cells. Recent advances in understanding the subtypes and plasticity of cells in the TME both open up …


Impact Of Glufosinate On Sugarcane Yield And Yield Components When Applied Post-Directed And Its Efficacy In Controlling Emerged Itchgrass (Rottboellia Cochinchinensis), Warner R. Simon Mar 2025

Impact Of Glufosinate On Sugarcane Yield And Yield Components When Applied Post-Directed And Its Efficacy In Controlling Emerged Itchgrass (Rottboellia Cochinchinensis), Warner R. Simon

LSU Master's Theses

Weed control is extremely important in the Louisiana sugarcane (Saccharum spp.) industry, as it is a perennial crop that grows back after each harvest. Fields are kept weed free using mechanical and chemical methods to prevent weed-crop competition and further establishment of weed populations. The weed itchgrass (Rottboellia cochinchinensis) has become problematic for Louisiana sugarcane producers. Sometimes, itchgrass can still emerge after farmers have made a pre-emergence (PRE) herbicide application. These weeds are usually controlled using the herbicide paraquat dichloride (paraquat) in post-emergence (POST) directed applications. In recent year, 2016-2024, the United States Environmental Protection Agency …


Synthetic Protein Mimetic Based Therapies For Neurodegeneration, Nicholas H. Stillman Mar 2025

Synthetic Protein Mimetic Based Therapies For Neurodegeneration, Nicholas H. Stillman

Electronic Theses and Dissertations

Protein-protein interactions (PPIs) are crucial for the regulation of a majority of, if not every fundamental cellular process. Despite their role in regular biological processes, dysregulated and/or aberrant protein-protein interactions (aPPIs) are often related to the onset of disease including cancer, viral infection, and amyloid diseases. aPPIs have historically been deemed ‘undruggable’ due to their large surface area and lack of a binding cavity; however, today, more than 40 disease-related aPPIs have been targeted with small molecules and several of those have reached clinical trials.

A class of synthetic protein mimetics called oligopyridylamides (OPs) has been shown to inhibit disease-related …

Department of Medicine Faculty Papers

Microglial diversity arises from the interplay between inherent genetic programs and external environmental signals. However, the mechanisms by which these processes develop and interact within the growing brain are not yet fully understood. Here, we show that radial glia-expressed integrin beta 8 (ITGB8) activates microglia-expressed TGFβ1 to drive microglial development. Domain-restricted deletion of Itgb8 in these progenitors results in regionally restricted and developmentally arrested microglia that persist into adulthood. In the absence of autocrine TGFβ1 signaling, microglia adopt a similar phenotype, leading to neuromotor symptoms almost identical to Itgb8 mutant mice. In contrast, microglia lacking the canonical TGFβ signal transducers …


Diverse Roles Of Stress-Responsive Rnp Granules In Oogenesis And Infertility, M. Rebecca Glineburg, Carolee Nguyen Mar 2025

Diverse Roles Of Stress-Responsive Rnp Granules In Oogenesis And Infertility, M. Rebecca Glineburg, Carolee Nguyen

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Effectively responding to cellular stress (e.g., nutrient deprivation, oxidative stress) is essential for cell and organismal survival. A protective mechanism is especially critical in developing oocytes, where a prolonged quiescent state and the inability to divide render oocytes highly susceptible to accumulating stress that can result in cell death if unaddressed. Despite the common view that stress granules are the primary stress-responsive ribonucleoprotein granule, accumulating evidence shows that in ovaries, other ribonucleoprotein granules also uniquely mediate gene regulation in response to stress. Here, we review recent insights into ribonucleoprotein granule dynamics and ribonucleoprotein granule protein function during stress in the …

Bryce Canyon Aspen: Recent Trends, Future Actions, Paul C. Rogers

Aspen Bibliography

In cooperation with Bryce Canyon National Park, we undertook a survey of quaking aspen (Populus tremuloides Michx.) conditions throughout the Park with the intention of better understanding conditions and prescribing corrective measures where needed. There are clear disparities within the Park between sustainable aspen conditions and failing stands. Based on condition of mature trees, but most importantly regeneration and recruitment of juvenile stems, most aspen forests within Bryce Canyon are in poor condition. Aspen recruitment—generally sapling-sized trees that have survived browsing ungulates—is the most important metric of future stand resilience and here we found 83% of all aspen sample …

Among different age groups, middle-aged individuals are particularly susceptible to obesity, with a 22% higher risk of all-cause mortality. However, the underlying mechanisms remain unclear. In this study, we identify adipose progenitor cells (APCs) in the white adipose tissue (WAT) of middle-aged subjects as potential causes of midlife obesity. Specifically, the extracellular vesicles (EVs) derived from APCs display an impaired ability to mitigate the inflammaging of adipose tissue macrophages (ATMs) in middle-aged individuals. Mechanistically, these EVs, lacking miR-145-5p, fail to suppress the expression of L-selectin in ATMs, thereby facilitating their M1 program via the NF-κB signaling pathway. In contrast, EVs …

  1. High latitude wetlands are ecologically important ecosystems due to their large carbon (C) storage capacity and because they serve as breeding and nesting habitat for large populations of migratory birds. Goose herbivory in wetland meadows affects leaf chemical and morphological traits and also influences soil properties by increasing soil temperature and depositing faeces. Grazing-induced changes to above-ground traits and soil properties impact C cycling, but the influence of grazing on root-mediated C and nitrogen (N) cycling has not been explored.

Variation In Response To Phosphorus Among Sweetpotato (Ipomoea Batatas L.) Cultivars, Jeffrey Cole Denis Gregorie Mar 2025

Variation In Response To Phosphorus Among Sweetpotato (Ipomoea Batatas L.) Cultivars, Jeffrey Cole Denis Gregorie

LSU Doctoral Dissertations

Phosphorus (P) is essential for plant growth and is often a major limiting nutrient in agriculture. In sweetpotato (Ipomoea batatas), studies on the role of P on storage root yield have been limited because of the lack of response and inconsistent results across cultivars and years. Growing evidence shows that current phosphate (Pi) fertilizer rates can be reduced while maintaining productivity. Newly published molecular evidence shows differential expression of phosphate starvation response genes among sweetpotato cultivars, further supporting the hypothesis of cultivar-specific Pi sensitivity. The research herein sought to characterize root system architecture and yield response to Pi …

Multi-Channel Features Combined With Gray Features For Remote Sensing Image Classification, Khaled Hasan, Hussien Harb, Lamiaa A. Elrefaei, Hala M. Abdel-Kader

Mansoura Engineering Journal

Image classification in remote sensing is crucial for various applications like deforestation monitoring and Land Use/Land Cover (LULC) mapping. While grayscale images offer simplicity, recent advancements have enhanced classification by integrating spatial and relative data. However, relying solely on grayscale images overlooks valuable color information from different channels. To overcome this, researchers have explored two strategies: combining diverse features and utilizing multi-channel features. These methods merge spatial information and exploit shared features across channels. Despite their improved performance compared to grayscale, they face increased dimensionality, necessitating dimensionality reduction techniques. In our study, we propose a novel approach that integrates spatial …

Targeting the dependency of MLL-rearranged (MLLr) leukemias on menin with small molecule inhibitors has opened new therapeutic strategies for these poor-prognosis diseases. However, the rapid development of menin inhibitor resistance calls for combinatory strategies to improve responses and prevent resistance. Here we show that leukemia stem cells (LSCs) of MLLr acute myeloid leukemia (AML) exhibit enhanced guanine nucleotide biosynthesis, the inhibition of which leads to myeloid differentiation and sensitization to menin inhibitors. Mechanistically, targeting inosine monophosphate dehydrogenase 2 (IMPDH2) reduces guanine nucleotides and rRNA transcription, leading to reduced protein expression of LEDGF and menin. Consequently, the formation and chromatin binding …
