Use Of Basal Tree Cavities By Sylvilagus Aquaticus In Central Arkansas, Heath R. Williams

ATU Scholars Symposium

Basal tree cavities are hollow structures at the base of tree trunks utilized by many wildlife species, including small mammals, furbearers, and bats. Dumyahn and Zollner (2010) demonstrated that swamp rabbits (Sylvilagus aquaticus) use basal tree cavities and speculated that they may be used for thermoregulation at the northern limits of their geographic range or as alternative escape routes. To further investigate swamp rabbit use of basal tree cavities, we placed camera traps approximately 1 m from the entrance of the cavities (n = 43) in various Wildlife Management Areas in central Arkansas. Along with control sites without cavities (n=25), …

Colostrum Fatty Acid Composition And Its Association With Reproductive Traits In Sows Under Tropical Conditions, Dwi Sunu Datrianto, Kunaporn Homyog, Surasak Jittakhot, Padet Tummaruk

The Thai Journal of Veterinary Medicine

Colostrum provides essential nutrients and immune factors that newborn piglets can absorb only within the first 24 h after birth. Fatty acids are essential for neonatal physiology, supporting thermoregulation, neurodevelopment, and immune function, and serving as a key energy source to reduce hypothermia and mortality in piglets. However, information on the fatty acid composition of sow colostrum under tropical conditions and its relationship with reproductive performance remains limited, warranting further investigation to improve piglet survival. This study evaluated the fatty acid profile of sow colostrum under tropical production conditions and examined its associations with reproductive traits. Colostrum samples were collected …

Play For All: Promoting Inclusivity And Providing Modifications For Kids With Disabilities Within An Indoor Play Space, Yasmeen Ikbal, Mary Jan Greer

Spring 2026 OTD Capstone Symposium

Children’s environments need to be enhanced to match their developmental levels (Winter & Dempsey, 1994). There is a lack of tools, play equipment, and structures specifically targeted to children with disabilities (Therrien et al., 2022). Lack of opportunities for these children can hinder their development (Mullick, 2013). This capstone intends to educate staff and parents on how to promote inclusivity by increasing their understanding of disabilities, creating accessible environments, adapting activities, and building confidence in supporting children with disabilities to participate in their occupations.

Β-Glucan Mitigates Valproic Acid-Induced Hepatorenal Toxicity In Rats, Maha Mohammad Almutairi, Hussein Mohammad Ali, Mohamed Abdelbakky, Ahmad Hamad Alhowail

Saudi Toxicology Journal

Valproic acid (VPA) is a common medication used to treat epilepsy, known for its broad-spectrum efficacy but also associated with hepatotoxicity and metabolic disturbances. β-glucan, a natural polysaccharide with hepatoprotective properties, may mitigate druginduced liver damage. The study sought to assess hepatorenal toxicity of VPA and investigate the potential protective and therapeutic effects of β-glucan. Forty male rats were randomly distributed into four groups. The treated group received VPA (500 mg/kg), β-glucan (50 mg/kg), or combinations for 14–21 days via intraperitoneal injection. Serum biochemical parameters (ALT, AST, ALP, urea, creatinine, lipids) were measured. Histopathological evaluation of hepatic tissue was performed. …

Aquatic biofilms are an understudied component of northern peatlands and are expected to play a more prominent role in ecosystem processes in areas where aquatic habitat is expanding. The goal of this study was to investigate how hydrologic history influences biofilm diversity and functional genes. This study was conducted in a long-term water table manipulation that simulates drought (lowered water table treatment) and flooding (raised water table treatment) conditions relative to a control treatment (no manipulation). We used a combination of metabarcoding and metagenomic approaches to (1) examine the diversity of eukaryotic algae, cyanobacteria, bacteria and fungi within the biofilm …

Systematic Design And Optimization Of Porous Bone Plates Using Taguchi Method And Finite Element Analysis, Aliaa A. Farraj, Tawakol A. Enab, Hanan M. Amer, Mostafa A. Elbahloul

Mansoura Engineering Journal

Solid bone fixation plates, although clinically effective, often induce stress shielding and impair periosteal blood flow due to their mismatch in stiffness with cortical bone. To overcome these limitations, this study proposes lattice-engineered porous bone plates designed to balance mechanical integrity and biological compatibility. A systematic parametric investigation was conducted by varying three design variables: crystal structure type (diamond, fluorite, and gyroid), porosity levels (50%, 70%, and 90%), and structure layout. Three-dimensional models were developed using nTopology, and finite element analysis (FEA) was performed under a static compressive load to evaluate stress distribution. A Taguchi L9 orthogonal array was employed …

Harnessing The Gut-Diet Axis To Enhance Chemotherapy And Immunotherapy, Jill Carline

Bryant REDay (Research and Engagement Day)

The human microbiome, a complex ecosystem of trillions of microorganisms including bacteria, fungi, and viruses, represents a critical "gut-diet axis" that significantly influences cancer progression and therapeutic efficacy. While a state of homeostasis supports systemic immunity, dysbiosis is linked to chronic inflammation and can actively promote resistance to standard cytotoxic chemotherapies and modern immune checkpoint inhibitors. Specifically, research indicates that Bacteroides fragilis (ETBF) promotes resistance to 5-Fluorouracil and Oxaliplatin in colorectal cancer by activating Notch1 receptors to inhibit apoptosis and push cancer cells into a resilient, stem-cell-like state. Conversely, the introduction of fiber-rich and fermented foods can cultivate beneficial bacteria …

Does Volume Cycling Elicit A Skeletal Muscle Hypertrophy Re-Sensitization Effect? A Comparison Of Constant Versus Cycled Resistance Training Protocols, Joshua C. Pelland

Electronic Theses and Dissertations 2020 - Present

Purpose: This study examined whether volume cycling in resistance training can elicit a skeletal muscle hypertrophy re-sensitization effect without muscle atrophy. We hypothesized that muscle size would be maintained during lower volume phases, that re-sensitization would occur following these phases, and that overall hypertrophy would be similar between cycled and constant volume conditions.

Methods: Thirty-seven trained men and women had their lower limbs randomized to either a constant volume (12 sets/week throughout) or cycled volume (alternating 4-week phases of 12 and 4 sets/week) condition for unilateral calf press training over 20 weeks. Lateral and medial gastrocnemius muscle thickness (MT), calf …

Detection Of Lupine Alkaloids In Earwax Of Sheep, Clinton A. Stonecipher, Stephen T. Lee, Benedict T. Green, Daniel Cook

Poisonous Plant Research (PPR)

Lupines (Lupinus spp.) are a common plant species located on western U.S. rangelands. Most livestock death losses due to lupine toxicosis occur in sheep. Cattle are often affected due to the teratogenic nature of lupines in which crooked calf syndrome can occur. Earwax has been used to detect lupine alkaloids in cattle, but it is unknown if the alkaloids in lupine can be detected in the earwax of sheep. The objective of this study was to evaluate earwax as a noninvasive specimen to determine sheep exposure to lupine. Fifteen sheep (45 ± 3.8 kg body weight) were group housed …

Selecting Dwarf Tomato Cultivars For Space-Limited Systems: Tradeoffs In Size, Yield, And Fruit Quality, Abigail Lazier, Bruce Bugbee, Noah Langenfeld

Plants, Soils and Climate Student Research

Global food systems face increasing pressure to produce more food with fewer resources, while urbanization limits access to traditional growing spaces. Urban agriculture offers a strategy to improve local food production, but space constraints remain a major challenge. Dwarf crops, bred to be compact and high yielding, can improve production efficiency in these systems. This study evaluated the growth habit, yield, and fruit quality of 18 dwarf tomato (Solanum lycopersicum) cultivars grown in controlled environment rooms under LED lights. Cultivars differed substantially in growth habit, size, yield and fruit quality. Generally, larger cultivars produced higher per-plant yields but …

Pleistocene Glacial Effects On North American Phylogeographic Patterns, Noah Garland, Ingrid Jordon-Thaden

Scholars Week

The biodiversity of alpine ecosystems are grossly underestimated, in turn threatening habitat loss. Much work is needed in this respect to better understand the process of speciation and extinction in these environments, given the threat of global climate change. We are testing hypothesis regarding rapid radiation of plant lineages both into and out of refugia in the context of dispersal during post-glacial and inter-glacial periods, focusing on the phylogeny of trans-Beringian alpine plant species by observing circumpolar lineages extending into southern portions of the North American Cordillera, the Rocky Mountains and the Intermountain Region.  Focal taxa include species of Draba …

We then detail procedures for tissue collection and immunofluorescence. This protocol provides a standardized approach for consistently modeling striatal stroke in mice, enabling mechanistic studies and preclinical therapeutic testing.

Development, Validation, And Comparative Evaluation Of A Rheotaxis-Based Microfluidic Device To Isolate A Subpopulation Of High-Performance Human Spermatozoa, Charlene S. Fournier

Electronic Theses and Dissertations 2020 - Present

Fertility has declined over the past decades, and male infertility is now recognized as contributing equally to the need for Assisted Reproductive Technologies (ART). Current clinical sperm processing methods rely on multiple centrifugation steps, which are time- and labor-intensive and may be detrimental to spermatozoa. Therefore, improved methodologies are needed to select functional, healthy spermatozoa while mimicking natural sperm selection. Microfluidics has expanded in reproductive biology and offers an efficient approach to selecting spermatozoa based on progressive motility and rheotaxis—their natural ability to swim against a constant flow. In this study, I developed a rheotaxis-based microfluidic device to isolate highly …

Electronic Theses and Dissertations 2020 - Present

Green sea turtles are impacted by their interactions with recreational fishing piers, but how these interactions affect their diet, behavior, and hooking risk remains poorly understood. The objective of this study was to characterize and quantify interactions between juvenile green turtles (Chelonia mydas) and a recreational fishing pier in southeast Florida. The goals were to evaluate how proximity to the pier influences turtle diet, behavior, and incidental hooking. We compared pier-hooked turtles with individuals captured on an adjacent reef and at a control site lacking a nearby pier. Dietary preferences were assessed using nitrogenous blood analytes and stable isotope analysis. …

Amyotrophic Lateral Sclerosis Risk Perceptions And Patient Burden, John William Glisson

Doctoral Dissertations and Projects

This quantitative, non-experimental, cross-sectional correlational study examined relationships among perceived environmental risk factors, depressive symptoms, and functional symptom burden in adults diagnosed with Amyotrophic Lateral Sclerosis (ALS). ALS is a progressive neurodegenerative condition with an unclear etiology, and some individuals attribute the diagnosis to environmental exposures such as pesticides or military service. The purpose of this study was to assess whether environmental risk perceptions were associated with depressive symptoms or functional impairment, and whether depressive symptoms were associated with functional status. Participants were recruited through online ALS support networks and advocacy organizations, resulting in a final sample of 145 adults …

On-Farm Research Guide, Matt Yost, Jody Gale, Earl Creech, Megan Baker, Jeffrey Austin, Grant Cardon, Cody Zesiger

All Current Publications

Many growers want to increase crop productivity and farm profitability. On-farm research is a way growers can achieve this goal by discovering answers to important questions about the benefits of using specific products or practices they are uncertain about or are unproven. Validating the efficacy of already-implemented practices is another important reason to do on-farm research trials (Nielsen, 2008). Each farm is unique and can benefit from individualized on-farm research, especially since university and industry researchers cannot study every product or practice for every unique field or farm growing condition. This how-to guide covers benefits and best practices for conducting …

Irrigation Water Loss And Recovery In Utah, Bradley S. Crookston, Troy Peters, Matt Yost, Burdette Barker

All Current Publications

When deciding which irrigation systems to adopt, permit, or promote, it is important to consider how their efficiency and losses affect the water balance of Utah’s watersheds and drainage basins. Irrigators have no control over precipitation and only limited control of surface waters entering and leaving the state, as most of those are controlled by legal agreements. However, Utah’s water managers, elected officials, and water users can consider how surface water flows and groundwater storage is affected by using more efficient irrigation systems. Sprinkler, surface, or drip irrigation systems each have trade-offs in irrigation application efficiency, cost, and other factors. …
