Invasive Phragmites Effect On Utah Wetlands Soil Composition, Cecilia Steffen, Rachel Wood, Madison L. Brown

Library/Life Sciences Undergraduate Poster Competition 2024

Introduction

• Invasive Phragmites australis (referred to as Phragmites), invaded Utah wetlands in the 1980's. Efforts have been made since then to remove Phragmites through various treatments.

• Phragmites outcompetes other wetland plants, causing it to be the dominant species. This is called a monoculture.

• Utah's wetlands are important for many species migrations, filtration, and nutrient cycling.

• How do Phragmites treatments effect soil nutrients and moisture? How do untreated Phragmites wetlands compare to native dominant wetlands?

Fish Tattoos: The Evolutionary Cost Of Black Spot Disease, Eric J. Morris, Jerry B. Johnson

Library/Life Sciences Undergraduate Poster Competition 2024

QUESTION

Does Black Spot Disease increase the fitness of male fishes?

HYPOTHESIS

We hypothesize that Black Spot Disease will increase the fitness of male fishes. We predict that female fishes will exhibit an association preference for infected males over healthy males when given the choice between the two. This observed preference would suggest that BSD is advantageous for male fishes

Exploring Soil Plant Relationships To Inform Seed Selection For Rangeland Restoration, Mallory Hinton, April Hulet, Matt Madsen, Raechel Hunsaker, Shannon Nelson

Library/Life Sciences Undergraduate Poster Competition 2024

Seeding plants post disturbance on rangelands is a challenge due to unique ecological and environmental conditions such as:

• Limited water availability1

• Invasive species2

• Soil health3

• Native seed supplies4

One of the key factors to address these challenges and have a successful seeding is to understand the relationship between soil properties and the plants that grow within them.

Exploring The Role Of Dopamine And Atp In Microglial Motility, Derek Langford, Jordan Yorgas, Christopher Galbraith, Channing Syme, Brayden Parker, Savannah Evans, Derek Langford, Eliza White, Erin Taylor, Lauren Ford, Hillary Wadsworth

Library/Life Sciences Undergraduate Poster Competition 2024

►Recent studies from our laboratory have identified that dopamine and ATP in the Nucleus Accubmens (NAc) are co-released.

►ATP is a chemoattractant for macrophages in general, and microglia specifically, suggesting that dopamine and ATP corelease may function to alter microglia activity.

►The present work characterizes the effects of microglia activation via lipopolysaccharide (LPS) on dopamine terminal function, and the effects of dopamine and ATP on microglia motility.

Effects Of Post-Translational Histone Modifications On Transcription Rate, Jacob Hunter, Steven Johnson, Aaron Bohn, Sarah Ricks, Sarah Hodson, David Bates, Steven M. Johnson

Library/Life Sciences Undergraduate Poster Competition 2024

DNA structure and organization in eukaryotic cells significantly impacts the regulation of geneexpression, cellular properties and overall behavior. At the most fundamental unit of this organization,~147 bp of DNA wraps 1.7 times around a histone octamer core, forming a collective unit called thenucleosome. Positioning and occupancy of nucleosomes around promoter elements of genes is knownto be a strong regulator of transcription in eukaryotic nuclei. Post-translational modifications (PTM’s) tothe protruding N-terminal tails of histone proteins are known to influence chromatin structure and thusgene expression; however, relatively little is known about the residual effect of histone PTM’s ontranscription rate.

Effects Of Grass Species And Soil Types On Early Successional Forb Species, Raechel Hunsaker, April Hulet, Matthew Madsen, Mallory Hinton, Derek Tilley

Library/Life Sciences Undergraduate Poster Competition 2024

Many early successional plant species have been considered weeds because of their lack of forage value for livestock (Whitson and Burrill, 2009). However, these early successional plant species have the potential to aid rangeland restoration in a variety of ways including:

• Food source for pollinators (Dumroese et al., 2016).

• Soil partitioning for climax communities of native perennials (Tilley et al., 2022).

• Competition against invasive annual species (Leger et al., 2014). To determine which early colonizing (or pioneer) species have the greatest restoration potential, interspecific competitive interactions should be evaluated.

Diversity And Community Of Macroinvertebrates In Timpanogos Caves, Utah, Erika Frandsen, C. Riley Nelson

Library/Life Sciences Undergraduate Poster Competition 2024

The Timpanogos Cave System consists of three caves in American Fork, Utah. In 2003, the National Park Service (NPS) commissioned Dr. Riley Nelson and laboratory students to conduct a survey of the diversity and abundance of terrestrial arthropod species found within the caves. Over the two years they sampled in Timpanogos Caves, they identified 55 species of macroinvertebrates in an unpublished report. In the 20 years since the last sampling, many environmental factors could have changed in these caves, contributing to an overall decrease in both abundance and biodiversity of fauna. Therefore, we repeated the sampling done by the Nelson …

Distinguishing Leukemic Cells Using Fractal Chromatin Patterns And Machine Learning, Abigail Gordhamer, Ryan Cordner, Paul Young

Library/Life Sciences Undergraduate Poster Competition 2024

One of the most important tests in the clinical laboratory is the Complete Blood Count, which involves identifying the white blood cells in a patient’s blood. The respective counts of the different white blood cell types correlate with various states of health and disease and are critical to diagnosing diseases such as leukemia. Leukemic cells (blasts) are considered especially difficult to distinguish, and it is of the upmost importance that these cells are identified correctly. To aid in the process of leukemic cell identification, we quantified fractal patterns in the chromatin of white blood cells and used the data to …

Determining The Role Of Noncoding Insertion And Deletion Mutations In Lung Cancer, Zachary Everton, Matthew H. Bailey

Library/Life Sciences Undergraduate Poster Competition 2024

Background

● Cancer is a disease in which cells grow and divide at an uncontrolled rate and cause damage to surrounding tissue and is caused by mutations in the cells’ DNA.

● Though some cancer-causing mutations are inherited from parents, most cancer-causing mutations emerge over the course of a person’s life and are localized to the tumor. These localized mutations are also known as somatic mutations.

● The human genome is over 6.27 billion base pairs long and cannot be read from end to end; instead it is read in small pieces that are aligned to best-matching sequences in the …

Changes In Environmental Conditions Affect The Two Isoforms Of Snap-25 Differently, Joseph Jackson, Dixon J. Woodbury, Tanner M. Blocker, Samuel W. Shumway, Jarom S. Sumsion, Thomas Weed, Jason Carlson, Nathan Mumford, Ryan Poland

Library/Life Sciences Undergraduate Poster Competition 2024

In the brain, neurons communicate via releasing and detecting neurotransmitters. Release occurs through exocytosis, following fusion of synaptic vesicles to neuronal cell membranes. This process is driven by formation of a dynamic quaternary protein structure known as the SNARE complex. SNAP-25 contributes two alpha helical domains to this complex. Neurons express SNAP-25 in two distinct isoforms, SNAP-25A (25A) and SNAP-25B (25B). These two isoforms vary by only 9 amino acids and are expressed differently depending on brain region and the developmental stage of the neuron [1]. The primary structures of 25A and 25B and their effect on SNARE complex formation …

Cattle Resource Selection On Late Fall Sagebrush Steppe Habitat In Idaho, United States, Larry Cole Kempton, April Hulet, Jim Sprinkle, Randy Larsen, Jameson Brennan, Dan Lauritzen, Sawyer Fonnesbeck, Justin Hatch

Library/Life Sciences Undergraduate Poster Competition 2024

Introduction Targeted cattle grazing is increasingly recognized as an effective method for controlling invasive grasses like cheatgrass in sagebrush-steppe ecosystems1. However, there's a lack of understanding about cattle distribution and their preference for invasives during the dormant season. One statistical model that provides insights into cattle distribution and the selection of resources (e.g., vegetation) is the Resource Selection Function (RSF) model2. Our research objective is to utilize a resource selection function to predict the probability of cattle selecting a particular location, in our case areas with higher cheatgrass abundance, based on environmental variables. The development of a resource selection function …

Bird And Small Mammal Preference For Water Developments, Lizzie Wilson, Randy Larsen

Library/Life Sciences Undergraduate Poster Competition 2024

 Different types of water developments nicknamed “guzzlers” have been installed in many different arid and semi-arid environments to provide water resources to game species in the state of Utah.

 Upland game guzzlers are usually covered by a sheet of metal and are used to target species like chukar partridge and quail (Figure 1).

 Big game guzzlers are open pools of water that are used to target species like mule deer and desert big horn sheep (Figure 2).  Most visitations to guzzlers are by native species not targeted by the guzzlers or wildlife management efforts (3).

Adhd Medication Is More Potent And Effective During Ovulation, Laurenf@Byu.Edu Ford

Library/Life Sciences Undergraduate Poster Competition 2024

• Women escalate psychostimulant abuse more quickly than men. Women who are prescribed psychostimulants for ADHD report fluctuations in drug efficacy that correspond to their menstrual cycle.

• In rodents, females acquire psychostimulant addiction more readily and release more dopamine (DA) in the dorsal striatum, an effect mediated by estrogen.

• However, the impact of the estrous cycle in the nucleus accumbens (NAc), a core region for learning and addiction in the ventral striatum, is underexplored.

• Here, we examine cocaine, methylphenidate (Ritalin), and methamphetamine (Desoxyn) effects on DA transmission in male and naturally-cycling female mice.

Adapting The Auxin-Inducible Degron (Aid) System To The Zebrafish Model Organism, Dennis Li

Library/Life Sciences Undergraduate Poster Competition 2024

The Auxin Inducible Degron (AID) system is a conditional and reversible protein degradation system naturally occurring in plants. In the presence of the hormone Auxin, the AID tagged proteins are recruited into the plant’s E3 ubiquitin ligase machinery, ubiquitinated, and marked for degradation1. To adapt the AID system to the zebrafish model organism, our lab generated lines co-expressing Arabidopsis Thaliana plant TIR1 protein and GFP tagged with AID (GFP-AID) in superficially-located mechanosensory hair cells (HC) of the lateral line system and in spinal cord neurons found deeper in the body. Upon auxin application, GFP-AID expressed in the superficial HCs was …
