Investigating Autonomous Ground Vehicles For Weed Elimination, Abraham Mitchell

Computer Science and Computer Engineering Undergraduate Honors Theses

The management of weeds in crop fields is a continuous agricultural problem. The use of herbicides is the most common solution, but herbicidal resistance decreases effectiveness, and the use of herbicides has been found to have severe adverse effects on human health and the environment. The use of autonomous drone systems for weed elimination is an emerging solution, but challenges in GPS-based localization and navigation can impact the effectiveness of these systems. The goal of this thesis is to evaluate techniques for minimizing localization errors of drones as they attempt to eliminate weeds. A simulation environment was created to model …

A Meta-Analysis For Laboratory Diagnostics For Coccidioidomycosis, Mary C. Cowen

Biological Sciences Undergraduate Honors Theses

Coccidioidomycosis, commonly referred to as Valley Fever, is a fungal infection found in arid regions of the southwestern United States and Mexico. Infection occurs through inhalation of airborne spores from Coccidioides species, Coccidioides immitis and/or Coccidioides posadasii, and proceeds in both pulmonary and disseminated fashions. Approximately 60% of patients with coccidioidomycosis remain asymptomatic, while 40% will experience symptoms. Within the literature, there are no papers that summarize sensitivity and specificity values between different tests; therefore, this paper presents sensitivity and specificity results across different tests and companies (Meridian, IMMY, and MiraVista).

Growth Of Methanogens On Kaolinite, A Clay That Has Been Identified On Mars, Hailey Littrell

Biological Sciences Undergraduate Honors Theses

Methanogens have been studied as a model for life on Mars for 28 years now in the Kral lab. The discovery of methane in the Martian atmosphere by ground-based and orbital observations as well as Curiosity Rover (Formisano, V. et al., Krasnopolsky, V.A. et al., Mumma, M.J. et al.) has added relevance to these types of studies. Methanogens were chosen due to their ability to live in harsh environments, very similar to the Martian terrain. In addition to methane in the atmosphere, phyllosilicate clays have also been identified. One of those clays is kaolinite. Kaolinite has been found to not …

Exploring Genomic Convergence For Adaptations To Freezing Environments In Polar Fish, Ethan Talley

Biological Sciences Undergraduate Honors Theses

Convergent evolution provides valuable insights into how natural selection shapes species traits. Genomic analysis of lineages that display convergent traits has the potential to identify candidate genes for environmental adaptations across the scope of entire genomes. One remarkable example of convergent evolution is the independent development of antifreeze proteins (AFPs) in phylogenetically distant polar fish lineages. While AFPs themselves are relatively well studied, the full genomic context of adaptation to freezing conditions in these fish lineages remains largely unexplored. Leveraging the whole genome sequences previously assembled in our lab, along with other high-quality genomes available in GenBank, I examined the …

Analyzing Phototaxis And Related Visual Behaviors Among Diverse Species Of Drosophila, Madeline M. Hill

Honors Theses

Phototaxis and related visual behaviors can vary between species, and thus members of the genus Drosophila make an excellent study system to examine the evolution of vision. While some existing research points to these phototactic behaviors arising due to mating requirements or due to their species-specific ecology or environmental factors, there exists a lack of understanding as to why striking behavioral differences can exist between closely related species, or between members belonging to the same genus. The present research seeks to uncover the specifics regarding these discrepancies in visual evolution and aims to provide a foundation of knowledge about visual …

Toxicological Effects And Treatment Of Accidental Ingestion Of Simparica Trio® In Felis Catus: An Investigative Review, Aussia Stander

Honors Theses

Simparica TRIO^®, a canine endectocide manufactured by Zoetis, contains sarolaner, moxidectin, and pyrantel pamoate salt in an orally administered chewable tablet. These compounds are all toxic to both cats and dogs in sufficient amounts. As Simparica TRIO^® rises in popularity among pet owners, Felis catus (felines, cats) in multi-pet households (households with both cats and dogs) are at increased risk of overdosage and toxicosis from accidental ingestion of Simparica TRIO^® due to their smaller weight.

Simparica TRIO^® is not for feline use and little literature exists on the symptoms of and treatment for accidental ingestion …

Investigating Large Repeats In The Arabidopsis Thaliana Mitochondrial Genome Using Mitotalens, Megan Gusso

Honors Theses

This lab project explores the complexity of the mitochondrial genome by investigating large genomic repeats and their effect on flowering plants’ reproduction and viability. Mitochondria are the site of cellular respiration to create energy and contain their own DNA. This is counterintuitive because the byproducts of cellular respiration impose a threat of mutation for the stored DNA. The mitochondrial genome differs in size between animals and plants. Plant mitochondrial DNA is larger due to the presence of large, noncoding repeated sequences, and a large amount of DNA of unknown function. These sequences undergo high levels of recombination and rearrangement. The …

Exploring The Impact Of Subject Placement On Exam Questions​, Briana M. Craig, Jeremy L. Hsu

Student Scholar Symposium Abstracts and Posters

Quizzes and exams are crucial elements of undergraduate biology courses; however, little research has been done exploring the importance of the phrasing used in the questions on these assessments. Question framing has the potential to impact student performance and sense of belonging greatly. In this study, we conducted an experiment where we created three versions of the exact same question except for the framing for the experimental scenarios. One version was written with self-referential framing using the term “you,” simulating the student conducting the experiment; another version used classmate-referential framing, placing one of their peers in the experiment; the third …

The Complexity Of Female Treefrog Mate Choice: Choosiness And Preferences Are Independent Behaviors And Each Are Prone To Separate Sources Of Variation, Olivia S. Feagles

Theses and Dissertations

Mate choice is an important cause of natural and sexual selection, driving the evolution of ornaments and promoting diversification and speciation. Mate choice decisions arise from the interaction of several components, and knowledge of whether they interact, and how, is crucial for understanding their contributions to selection. There are multiple components of mate choice theoretically proposed, and here I focus specifically on preference functions (attractiveness ranking of prospective mates) and/or choosiness (willingness to invest effort in obtaining the preferred mate). Objective 1 (addressed in Chapter I) of this dissertation focuses specifically on the relationship between preferences and choosiness, testing the …

Investigating An Optimal Motor Learning Protocol That Leads To Better Savings And Long-Term Retention Of Visuomotor Adaptation, Reshma James

Theses and Dissertations

Visuomotor adaptation is fundamental to everyday activities, from the simple act of reaching for a cup to complex athletic maneuvers. The concept of savings is particularly interesting as it sheds light on how motor skills are acquired, retained, and relearned over time. Savings refers to the phenomenon where motor skills that have been previously learned are reacquired or relearned more rapidly after a period of inactivity or after the individual has undergone de-adaptation. While it was initially believed that savings in motor adaptation stemmed from implicit learning mechanisms, recent research indicates that it is primarily attributed to explicit recall of …

Accuracy And Precision Of Wearable Camera Media Annotations To Estimate Dimensions Of Physical Activity And Sedentary Behavior, Julian Martinez

Theses and Dissertations

Physical activity (PA) is a complex behavior to measure given its sporadic nature and its all-encompassing definition as bodily movement produced by skeletal muscles that result in increased energy expenditure. Sedentary behavior (SB) is another complex health behavior to measure as it is more exactly defined as sitting, reclining, or lying while having an energy expenditure ≤ 1.5 metabolic equivalents (METs). For both PA and SB, it is important to measure the dimensions of frequency, intensity, duration and type of activity being performed when associating the volume of PA and SB with different health outcomes. However, commonly used measurement tools …

Theses and Dissertations

Gender in forest schools is a topic that should be at the forefront of discussion when creating a forest school, its pedagogy, curriculum, and principles. Gender is a large part of who we are as humans and having teachers aware of its complexities, presentation, and presence in the forest school setting is imperative. This study consists of interviews and focus group data collected at a midwest United States public forest preschool and an eastern United States private forest preschool. The teachers at these schools were cisgender, as were the students ages three through five who were observed. This paper analyzes …

Quantifying Within-Population Variation In Mate Choice; Discrimination, Mate Sampling Rules, Multivariate Preference & Consequences For Sexual Selection, Kane David Stratman

Theses and Dissertations

Mate choice is foundational to the evolution of elaborate, conspicuous, and often energetically costly displays. Modelling sexual selection in any mating system is a complicated task on two fronts; we typically confront variation in both i) the strategies of signalers and ii) how choosers assess and sample among them. As selection on mate choice behaviors emerges from the relationship between these sources of variation, it is essential that they be measured in detail. Population-level measures of chooser behaviors (i.e. pooling the single responses of a sample of choosers) have long dominated the literature on mate choice, leaving open the possibility …

Analyzing The Effects Of Sex-Biased Gene Expression On Dosage Compensation: An Exploratory Investigation Of Gene Expression Differences In Tribolium Leg Tissue, Preston Q. Truong

2024 Spring Honors Capstone Projects

The XX/XY sex chromosome system governs the sex determination of many organisms, where female individuals typically possess the XX sex chromosome pair and male individuals possess the XY pair. However, in some species, the Y chromosome is degraded due to reduced recombination and genetic processes that results in the loss of gene content. Dosage compensation (DC) mechanisms evolve to counteract the significant loss of one copy of genes and serves to maintain the level of gene expression before the loss of one copy of genes. This study will explore how sex-biased gene expression may affect DC evolution by observing the …

Uncovering Novel Small Regulatory Rna In Protostome, Sweta Khanal

Dissertations

Small RNAs play pivotal roles in post-transcriptional gene regulation across diverse phylum of protostomes. In this study, we investigate the functional significance of atypical miRNAs, mirtron miR-1017 in Drosophila. Through ectopic expression in neuronal cells, we demonstrate that miR-1017 extends lifespan by targeting its host transcript, acetylcholine receptor Dα2, and influencing its splicing. This novel trans-regulatory function suggests a mechanism for mirtron evolution, highlighting the interplay between splicing and post-transcriptional regulation. Additionally, we profile small RNA populations in the polychaete developmental model Capitella teleta, shedding light on the small RNA landscape in annelid worms. Our analysis reveals a rich …
