Social Isolation Predicts Altered Reward Circuit Connectivity And Future Behaviors In Adolescents, Mason Lucas
Social Isolation Predicts Altered Reward Circuit Connectivity And Future Behaviors In Adolescents, Mason Lucas
2026 Research Poster Competition
Adolescence is a period of transition from childhood to adulthood when people explore risky behaviors. Stressors during adolescence can change structural brain connectivity. Previous research has found weaker structural connectivity between reward circuits and future cognitive impairments among children raised in orphanages. Comparative research in mice suggests that social isolation after bullying can damage these connections and induce alcohol seeking. We tested whether social isolation was related to lower connectivity of targeted structural connections in adolescent humans. We analyzed data from the Adolescent Brain Cognitive Development study and found 130 subjects had experienced extreme social isolation. To evaluate the level …
From Chaos To Clockwork: Investigating The Role Of Circadian Genes In Metabolic Development Of 2nd And 3rd Instar Drosophila Larvae, Elliott Ruegsegger
From Chaos To Clockwork: Investigating The Role Of Circadian Genes In Metabolic Development Of 2nd And 3rd Instar Drosophila Larvae, Elliott Ruegsegger
2026 Research Poster Competition
Connecting deficits in circadian rhythm machinery to the severity of other health conditions is a common task that chronobiology, the study of physiological rhythms, undertakes. Disruptions to circadian rhythms and sleep are linked to increased risk of developing multiple different diseases, including Alzheimer’s Disease and obesity. Circadian rhythms are expressed at the molecular level through rhythmic variations in the concentration of specific proteins. While the central clock genes that produce these proteins, such as period and timeless, are evolutionarily conserved across the animal kingdom, not much is known about the consequences of disruptions in circadian rhythm machinery during early development, …
Moving Towards Defining The Evolutionarily Ancient Role Of Notch Signaling In Animals., Paige Norris
Moving Towards Defining The Evolutionarily Ancient Role Of Notch Signaling In Animals., Paige Norris
2026 Research Poster Competition
The notch signaling pathway is deeply conserved across animals from humans to sponges. It functions through direct cell-to-cell communication, where ligand binding triggers the cleavage of the Notch receptor’s intracellular domain (NICD), which then translocates to the nucleus to regulate transcription. In bilaterian lineages—animals with bilateral symmetry— Notch signaling is known to regulate binary cell fate decisions in diverse contexts ranging from neurogenesis to cancer. However, the functions of Notch signaling in early-branching animals, including cnidarians (e.g. jellyfish, corals and sea anemones), are still not fully understood; consequently, evolutionarily ancient roles of Notch remain ill-defined. To address this fundamental knowledge …
Methanogens On Asteroids?, Isabella Reimer
Methanogens On Asteroids?, Isabella Reimer
2026 Research Poster Competition
Methanogens on Asteroids? Introduction: It is conceivable that if methanogens, microorganisms in the domain Archaea, exist on Mars, they were seeded there from a piece of Earth that was ejected by a meteor impact sometime in the past, or that material from Mars seeded our home planet by the same mechanism. The hypothesis of panspermia, the idea that life could be transported from one planet to another through space, was first developed by Arrhenius in 1908 (1). Since then, the idea of lithopanspermia, the transfer of organisms in rocks such as meteors and asteroids, has become amenable to testing. Previous …
Investigating Pituitary Specific Transcription Factor-1 (Pit-1) In Neuronal Development In The Sea Anemone Cnidarian Nematostella Vectensis, Emily Ye
2026 Research Poster Competition
In bilaterians — animals with bilateral symmetry, like vertebrates and insects — the pituitary specific transcription factor-1 (pit-1) is essential for regulating growth hormone and prolactin expression in the pituitary gland. However, in non-bilaterians, the ancestral function of pit-1 remains unknown. Cnidarians, such as the sea anemone Nematostella vectensis, form a sister group to bilaterians and lack a pituitary gland, making them a powerful model for investigating the early evolutionary role of conserved developmental genes, like pit-1.Using CRISPR-mediated gene editing, pit-1 knockout mutants — anemones without the pit-1 gene — were generated, and their transcriptomic, cellular, and behavioral phenotypes were …
Investigating Changes In White Blood Cell Composition In Wild Hosts In Response To Viral Infection, Anna Bolding
Investigating Changes In White Blood Cell Composition In Wild Hosts In Response To Viral Infection, Anna Bolding
2026 Research Poster Competition
Reservoir hosts play a critical role in the persistence and spillover of zoonotic pathogens. Upon infection, reservoir hosts can shed viral loads sufficient for transmission and spillover often without displaying apparent pathogenic effects. Investigating how their immune systems control infection can provide insights into the factors that facilitate spillover events. Understanding the mechanisms that enable these infection characteristics is crucial for informing public health and conservation strategies. Though reservoir hosts’ immune responses are well-documented in controlled laboratory settings, these studies are not representative of natural populations. The bank vole - Puumala hantavirus (PUUV) system is well suited for investigating such …
Soil Moisture Regime Effects On Near-Surface Soil Chemical Properties In Alfisols Under Native Tallgrass Prairie In Arkansas, Sydney Talley
Soil Moisture Regime Effects On Near-Surface Soil Chemical Properties In Alfisols Under Native Tallgrass Prairie In Arkansas, Sydney Talley
2026 Research Poster Competition
Tallgrass prairie ecosystems provide many crucial ecosystem services, including nutrient cycling and storage, organism habitat, and soil and water conservation. However, tallgrass prairies are considered endangered ecosystems, particularly in the Ozark Highlands and Grand Prairie regions of Arkansas, where less than 0.05% of the state's original prairie land area remains. Understanding soil nutrient supplies over time in native tallgrass prairie ecosystems is critical for quantifying the success of restoration and rehabilitation activities. The objective of this study was to evaluate the effects of soil moisture regime (SMR) (i.e., aquic and udic), region (i.e., Ozark Highlands and Grand Prairie), and their …

2026 Research Poster Competition
The objective of this study is to determine the effect of zinc supplementation in cattle feed on beef cattle during gestation and the influences of the trace mineral zinc on colostrum and calf immunocompetence measuring immunoglobulin concentrations and body weight. Cow-calf systems rely on the effectiveness and consistency of their nutritional intake. Beef cattle are fed forages and grain alongside specific minerals and supplements to meet nutritional requirements. The effectiveness of these trace minerals added to the diet helps to ensure that the animal gets the most out of its feed and the producer gets the most out of the …
Investigating The Potential Role Of Horse Flies (Diptera: Tabanidae) In The Mechanical Transmission Of Anaplasma Marginale And Theileria Orientalis To Cattle In Northwest Arkansas, Catherine Harrison
Investigating The Potential Role Of Horse Flies (Diptera: Tabanidae) In The Mechanical Transmission Of Anaplasma Marginale And Theileria Orientalis To Cattle In Northwest Arkansas, Catherine Harrison
2026 Research Poster Competition
The cattle industry in Arkansas plays a significant role in the state’s agricultural economy; however, two emerging infectious diseases pose a threat to cattle health, producer livelihood, and animal welfare. The two diseases, anaplasmosis and theileriosis, are caused by organisms that enter the host’s bloodstream and infect red blood cells, leading to destruction of said cells. The shared symptoms of both diseases are fever, weakness, anemia (low red blood cell count), reduced productivity, weight loss, and possibly death. An important difference between symptoms is that, unlike anaplasmosis, theileriosis can cause abortion in cattle. Both diseases are known to spread through …
Differences In Cytokine Mrna Expression At The Site Of Primary And Secondary Vaccinations With Herpesvirus Of Turkeys (Hvt) In Egg-Type Chickens., Allie Bowerman
2026 Research Poster Competition
Marek’s disease, a lymphoma causing virus, remains a major concern in poultry production systems. Although vaccination with live herpesvirus of turkeys (HVT) is crucial for controlling this disease, information on how the vaccine drives local/tissue immune responses that lead to protective immunity is limited. Using the growing feather (GF) in vivo bioassay, we assessed local cytokine mRNA expression following primary and booster intradermal (i.d.) HVT vaccinations in egg-type chickens. For this, six 9-week-old and six 19-week-old Light-brown Leghorn (LBL) pullets were i.d. injected into the pulp of growing feathers (GF; 10 µL/GF; 16 GFs/bird) with a primary (V1) or secondary …
Examining Life Course Trends In Dental Tissues Measurements In Members Of The Cayo Santiago Macaque Colony, Tyler Moore
Examining Life Course Trends In Dental Tissues Measurements In Members Of The Cayo Santiago Macaque Colony, Tyler Moore
2026 Research Poster Competition
Dental tissue dynamics in primates are largely understood: as enamel wears with tooth use, tertiary dentin is laid down in response to cumulative (micro)traumas, compressing the internal pulp chamber and root canals. However, our knowledge of the rate and pattern of change in tissue quantities across the life course of primates remains incomplete, particularly in well-documented free-ranging populations. This study examined age- and sex-related variation in dental tissue surface area (SA) and volume (V) in a skeletal sample of rhesus macaques (Macaca mulatta) from the Cayo Santiago colony (Puerto Rico), a population with known life history data. Forty-six individuals were …
Predictors Of Stigma And Their Relation To Mental Health Help-Seeking Attitude In College Students, Esiquil Lara
Predictors Of Stigma And Their Relation To Mental Health Help-Seeking Attitude In College Students, Esiquil Lara
2026 Research Poster Competition
Stigma remains a significant barrier for college students seeking mental health services, yet its predictors and impact are still not fully understood. Mental health problems are a large issue in public health, specifically college age adults are one of the most likely groups to develop such issues. This study examines key factors contributing to stigma and its relationship with help-seeking attitudes among undergraduate college students. We hypothesize that students who identify with minority ethnic groups, identify as male, and who are not seeking a career in mental health services will have higher rates of stigma and therefore be less likely …
Functional Characterization Of The Reniform Nematode Effector Protein Rr6640 In Soybean Parasitism, Noah Solomon
Functional Characterization Of The Reniform Nematode Effector Protein Rr6640 In Soybean Parasitism, Noah Solomon
2026 Research Poster Competition
Reniform nematode (Rotylenchulus reniformis, RN) is a major plant-pest affecting key crops in Arkansas such as cotton and soybean, causing economic losses exceeding $757 million in the U.S. over the past decade. While some genetic resistance exists in cotton, soybean remains highly susceptible, exacerbating RN populations in crop rotations. To address this gap, this research investigates the mechanisms of nematode infection focusing on effectors, the specialized proteins secreted by the parasite to manipulate host cell biology and suppress plant immunity. This study characterizes Rr6640, a putative effector gene identified as an ortholog to a virulence factor in the Beet Cyst …
Effectiveness Of Occupational Recommendations In Maintaining Cognitive Function Under Hot-Dry And Warm-Humid Conditions, Zane Garner
2026 Research Poster Competition
National Institute for Occupational Safety and Health (NIOSH) recommendations dictate heat safety practices in occupations throughout the United States.

Low crude protein (CP) diets can improve feed efficiency and reduce ammonia emissions, but negative impacts on broiler productivity can occur. This study aimed to evaluate the effects of gamma-aminobutyric acid (GABA) supplementation in low CP diets on productivity, enzyme activity, neuropeptidergic gene expression, and behavior of broilers. A total of 360 male Ross 308 broilers were used in a factorial design experiment with two CP levels (19.5 and 18.0%) and three GABA levels (0, 100, and 200 mg/kg). Dietary CP and GABA levels did not significantly affect broiler productivity (P>0.05). Reducing CP in the diet increased amylase and …

Does Phytase Change How We Feed Breeders?, Wenting Li
Does Phytase Change How We Feed Breeders?, Wenting Li
Proceedings of the Arkansas Nutrition Conference
Dietary evaluation of the use of exogenous phytase has received considerable attention in broilers, but not broiler breeders. Moreover, the limited studies that have assessed phytase in broiler breeders are dated, which makes interpretation problematic because dated phytase enzymes are not as efficacious as current phytase enzymes. The article addressed practical applications for dietary phytase in broiler breeder diets.
