Effectiveness Of Silvicultural Options In Renewal Of Trembling Aspen–Jack Pine Mixedwood Stands, 21 Years After Treatment, Rongzhou Man

Aspen Bibliography

Regenerating conifers after harvest through planting and postharvest broadcast application of herbicide is effective in ensuring the survival and growth of seedlings, but faces challenges in meeting broad social and ecological objectives of forest management. This study reports the effectiveness of alternative options in regenerating jack pine (Pinus banksiana Lamb.), 21 years after harvest of trembling aspen (Populus tremuloides Michx.)-dominated boreal mixedwood stands. The treatment options included (i) preharvest spray—aerial broadcast spray prior to harvest, (ii) postharvest partial spray—ground herbicide application in strips, (iii) partial harvest in strips, (iv) postharvest aerial broadcast, and (v) uncut reference. Twenty-one years …

Missense Mutation Of Msh6 Leucine 696 Has No Apparent Effect On The Dna Mismatch Repair Process, Razan H. Hammad, Rafia Rashid, Essence Tarrence, Christopher Bolden, Joanna E. Haye-Bertolozzi

XULAneXUS

Lynch Syndrome and Constitutional Mismatch Repair Deficiency are human diseases implicated in mutations of DNA mismatch repair (MMR) genes. This experiment tested a mutation of an MMR gene, MSH6, and evaluated how the mutation affected overall MMR effectiveness. Using the yeast Saccharomyces cerevisiae, we performed the CAN1 forward mutation assay to study msh6-L696F and its implications in the MMR process. We hypothesized that there would be a significant change in molecular function in the Msh6 protein in the presence of this mutation. Bioinformatic tools predicted that this amino acid change would have deleterious effects on MMR function. However, …

Michigan Tech Publications

The extent and distribution of tropical peatlands, and their importance as a vulnerable carbon (C) store, remain poorly quantified. Although large peatland complexes in Peru, the Congo basin, and Southeast Asia have been mapped in detail, information on many other tropical areas is uncertain. In the Eastern Colombian lowlands, peatland area estimates range from 700 km2 to nearly 60,000 km2, leading to highly uncertain C stocks. Using new field data, high-resolution Earth observation (EO), and a random forest approach, we mapped peatlands across Colombian territory East of the Andes below 400 m elevation. We estimated peatland extent using two approaches: …

The Effects Of Roundup® On Progression Of Parkinson's Disease Symptoms In A Mouse Model, Cora Knueven, Jenna Kidwell, Kaitlyn Carver, Sabrina Wilson, Trevor Walker, Ty Namik, David Tomlinson, Sydney Boutros

2025 Undergraduate Research Showcase

Glyphosate-Based Herbicides (GBH) are the most widely used herbicides worldwide. Concerns about the effects of GBH on human health have grown, specifically pointing towards a connection between chronic exposure and neurodegenerative diseases like Parkinson’s disease (PD). PD is characterized by the accumulation of phosphorylated alpha synuclein (aSyn). Previous rodent experiments have shown that introduction of aSyn pre-formed fibrils (PFFs) can induce progressive accumulation of PD-like pathology. We explored the effects of chronic, low-dose GBH exposure in a mouse model of PD. We induced PD-like pathology in male and female wildtype mice by injecting PFFs into the striatum. A control group …

Barriers To Care Within The Nampa Population, Jenni Matthews, Sydney Nickel

Can I Trust You To Be A Friend? Investigating The Role Of Women's Friendship Preferences In Friendship-Making Decisions, Annie Boyle, Jessica D. Ayers

2025 Undergraduate Research Showcase

Although research has documented the importance of friends, little research has explored the impact of women’s preferences on whether people want to be their friends. This study builds off Bradshaw (2021) to investigate how women’s friendship preferences influence the likelihood of her pursuing potential friends. We hypothesized that 1) women who prefer to have male friends (guys’ girls) would have higher sociosexual orientation (SOI) scores compared to women who prefer to have female friends (girls’ girls) and 2) participants who viewed a profile of a guys’ girl would rate her as having lower SOI attitudes than participants who viewed a …

How Does Coach Created Motivational Climate Influence Athlete Passion And Burnout?, Paige Mccrindle, Eric M. Martin

2025 Undergraduate Research Showcase

This study investigated the influence of coach-created motivational climate on passion and burnout in adolescent athletes. Drawing on Achievement Goal Theory, it examined how task-oriented and ego-oriented coaching environments influenced the two types of passion (i.e., harmonious and obsessive) and three aspects of burnout (i.e., physical and emotional exhaustion, reduced sense of accomplishment, and sport devaluation). Therefore, the research project had three primary research questions: 1) How do adolescent athletes perceive their coach-created motivational climate, and own levels of passion and burnout? 2) How does a coach-created environment influence athlete levels of passion and burnout? and 3) Do athlete’s perceptions …

Targeted Communication For Climate Denial: Ideologically Framed Survey Messaging, Allie Hampton, Jacob Meyer, Sean Walther, William Farkas

2025 Undergraduate Research Showcase

Climate change denial prevents meaningful environmental action. Current approaches, like overwhelming deniers with lists of facts and polarizing language, exclude individuals who might otherwise engage in discussion about climate issues. With an understanding of the barriers to entry of climate communication, local demographics, and successful communication strategy, we addressed the primary research question: what is the relationship between climate change messaging and respondents’ opinions on environmental issues? We collected survey data of 108 people on Boise State’s campus using two distinct flyer designs: one explicitly referencing “climate change” and another emphasizing “Idaho’s outdoors.” We found that individuals who engaged with …

2025 Undergraduate Research Showcase

People with intellectual and developmental disabilities (IDD) often experience difficulties accessing transportation, which can limit their independence and participation in the community. In this study, undergraduate peer interventionists used Google Maps, constant time delay, and total task chaining to teach young adults with IDD to navigate public transportation. Young adults with IDD were enrolled in an inclusive post-secondary education program and undergraduate students served as peer interventionists. An experimental, single-case multiple probe across participants design (Horner & Baer, 1978) was used to evaluate the effects of total task chaining with constant time delay on the number of independent steps completed. …

Cell Surface Modification With Lipophilic Linkers, Noor Hassun, Aviana Smith, Addison Hobson, Michael Muench, Aaron Stone, Daniel Fologea

2025 Undergraduate Research Showcase

Cell surface modification with bioactive groups is useful for adjusting their interactions and responses to chemical and physical stimuli. One method of surface modification is overexpression of membrane receptors, but this is time-consuming and restricted to membrane proteins. When non-protein molecules are needed for functionalization, chemical addition of bioactive groups may affect cell viability due to the use of harsh chemicals. To mitigate these shortcomings, we investigated the modification of cell surfaces by employing lipid-like linkers, which not only act quickly but also minimize the use of harsh chemicals. These lipid-like linkers carry a bioactive molecule at one end, while …

Markerless Motion Capture Overestimates Knee Flexion During Walk And Run Tasks, Aidan M. Thayer, Mikala A. Hicks, Tyler N. Brown

2025 Undergraduate Research Showcase

Low-cost markerless motion capture systems, such as OpenCap, have shown recent promise for accurate kinematic analysis of human motion during several activities, including walking, squatting, and drop landing. Although this technology has shown promise within a controlled laboratory space, its ability to accurately quantify kinematics in less controlled environments, like a recreational run, is unknown. The focus of this study was to determine if markerless motion capture, OpenCap, could accurately quantify knee kinematics during both a walk and run trial with body-borne load and over an uneven surface. Thus, 18 participants had their knee kinematics quantified during a walk (1.5 …

Many leave their roles prior to graduation, and this study sought to explore why student employees leave their jobs with OIT and how this information may be used to reduce student turnover rates. Student employment data from 9 departments with employee departure dates between 2021-2024 was analyzed using R Studio, pivot tables, and graphs. Among the student employees who left OIT voluntarily, nearly half (33 students) left in May, …

Quantification Of Ethyl-Cellulose Coated Vitamin C Using Near Infrared Spectroscopy, Logan Moynagh, Mia Toronto, Owen Mcdougal

2025 Undergraduate Research Showcase

Fourier Transform Near-Infrared Spectroscopy was used to compare six different concentrations of vitamin c mixed with ethyl cellulose. This was done by measuring the absorbance of a solid sample. In the spectra it was observed that there were three distinct peaks for different functional groups and overtones including oxygen-hydrogen stretch, carbon-hydrogen stretch, and oxygen-hydrogen bend. At these peaks, the spectra were ordered nicely from lowest to highest vitamin c concentration and lowest to highest absorbance. This is very promising as the current method for quantifying vitamin c in ethyl cellulose involves boiling the solution, which denatures the vitamin c, potentially …

Gains From Trade And Proportional Output Effects On Total Factor Productivity Growth In Wto Member Nations, David Barbour

2025 Undergraduate Research Showcase

Global trade has grown enormously over the decades with world exports nearing 26 trillion USD and there are now 166 member nations of the World Trade Organization (WTO), the world’s largest trade organization. While not without any costs, the broad uncontroversial consensus seems to be that trade has benefited the world and has done so by raising the wealth of all nations involved. The proposed mechanism of this action is in specialization and efficiency gains, measured in this paper as Total Factor Productivity (TFP). The WTO acts to lower trade barriers and encourage broad trade, but most countries go even …

Investigating The Potential Role Of Beneficial Bacteria In Big Sagebrush Restoration, Abbagayle S. Hannebaum, Elle Horwath, Leonora Bittleston

2025 Undergraduate Research Showcase

Microbes play an essential role in plant ecology, supporting growth, pathogen protection, and drought tolerance. Big sagebrush (Artemisia tridentata), a foundational plant species, hosts a diverse microbial community, but the benefits of its leaf microbiome remain unclear. We conducted an experiment to determine if the bacterial species, Bacillus amyloliquefaciens, may promote sagebrush growth and survival in a restoration setting. Seeds from Hillside to Hollow (HH) and Polecat Gulch (PC) were grown in a greenhouse, and once leaves emerged, the seedlings were randomly assigned to receive an inoculum containing B. amyloliquefaciens or a sterile water control. Before outplanting, …
