When Cooking Sous Vide, Do Different Bags Change The Color Reading Of The Spectrophotometer?, Kathryn Beard, Thomas Powell

Steeplechase: An ORCA Student Journal

Meat color changes over the course of cooking and storage. Companies for many years now have been measuring the color changes of meats when both cooking and storing over a period of time. When it comes to packaging there are two ways to measure color, through the packaging or by taking the meat out and measuring. Measuring the meat in the bag allows you to keep the process of whatever you are studying going, without ruining it by taking the meat out of the bag. The purpose of this project was to see if using different kinds of film cooking …

Seven Recipes To Save Yourself, Megan Bachman

B.F.A. Practicum Exhibition (ART 498)

Food is an undeniable constant. Food can be a declaration of love, gratitude, or wealth. It can be a reflection of individuals, as well as communities. The relationship between a person (or character) and food can speak volumes to the audience about who they are and how they interact with the artist's world. I am inspired by the works of Domee Shi (Director behind Bao and Turning Red) and Hayao Miyazaki (Director behind Studio Ghibli). They use food to further their narrative, and do so with enticing colors, textures, and sounds. That is why I chose to create posters …

Phenotypic Plasticity Of Male Calls In Two Populations Of The Katydid Neoconocephalus Triops (Insecta: Tettigoniidae), Oliver M. Beckers, Teiya Kijimoto, Johannes Schul

Faculty & Staff Research and Creative Activity

The ability to respond to environmental changes plays a crucial role for coping with environmental stressors related to climate change. Substantial changes in environmental conditions can overcome developmental homeostasis, exposing cryptic genetic variation. The katydid Neoconocephalus triops is a tropical species that extended its range to the more seasonal environment of North America where it has two reproductive generations per year. The harsher winter conditions required adults to diapause which resulted in substantially different mating calls of the diapausing winter animals compared to the non-overwintering summer animals in northern Florida. The summer call corresponds to that of tropical populations, whereas …

Risks Vs. Benefits Of Animal-Assisted Interventions For Icu Induced Psychosis, Cecily Christie, Hadley Mayes

Multi-Species Host Use By The Parasitoid Fly Ormia Lineifrons, Kyle J. Rogers, Oliver M. Beckers

Faculty & Staff Research and Creative Activity

Antagonistic species relationships such as parasitoid/host interactions lead to evolutionary arms races between species. Many parasitoids use more than one host species, requiring the parasitoid to adapt to multiple hosts, sometimes being the leader or the follower in the evolutionary back-and-forth between species. Thus, multi-species interactions are dynamic and show temporary evolutionary outcomes at a given point in time. We investigated the interactions of the multivoltine parasitoid fly Ormia lineifrons that uses different katydid hosts for each of its fly generations sequentially over time. We hypothesized that this fly is adapted to utilizing all hosts equally well for the population …

Quantitative And Qualitative Analysis Of Mutation In Pam-1 Of Model Organism Caenorhabditis Elegans., Jessica Stein, Jessica Stein

Honors College Theses

The pam-1 gene in the model roundworm Caenorhabditis elegans governs meiotic exit and establishment of cellular polarity in the single-celled C. elegans embryo. Mutation of the pam-1 gene results in reduced fertility and fecundity in adult C. elegans and disrupts the anatomy of the germinal gonad. The aim of this study is to qualitatively and quantitatively define the changes in the germline cells associated with mutations to the pam-1 gene. Specifically, we examined the stages of germ cell development within the gonads of adult worms, both wild-type and pam-1 compromised, and identified the changes in the length of the mitotic, …

The Opioid Epidemic: How Genetics Play A Role In Addiction And Treatment, Kirsten Houston

Honors College Theses

The opioid epidemic is an issue within the pharmaceutical industry in the United States of America due to prescription and non-prescription substances being made available to the population. Opioids include chemical substances that affect the body and brain through opioid receptors, including the mu, kappa, and delta receptors. These substances are derived and synthesized from the poppy plant. Multiple causes have been linked to opioid abuse disorder, including but not limited to employment, income, housing, nutrition, mental health disorders, and genetics. By gathering information from previous literature, genetics may be the main cause of narcotic analgesic tolerance and abuse. Specific …

An Argument For The Utilization Of Amphibian Stress As An Indicator Of Wetland Condition, Andrew W. Sisson

Honors College Theses

Traditional forms of rapid wetland condition assessments focus on foliage health, nutrient enrichment, chemical contamination, and surrounding land usage, often overlooking an evaluation of the animals living in the wetland. More intense assessments include the National Wetland Condition Assessment (NWCA) and indices of biotic integrity, which focus on community composition (e.g., diversity and species richness) and abundances. These indices require expertise in species identification and do not provide information about the animal’s fitness. Animal stress physiology, which generally correlates with measures used to quantify animal fitness (e.g., survival, reproduction, and body condition), may provide a complementary rapid assessment method aimed …

An in-depth analysis of online articles and journals was compared to the results of a survey of pet owners and veterinary professionals to obtain results for the study. The results of the analysis of online resources revealed that many pet owners are stressed about paying for veterinary care for their animal and that most are unprepared …

Sex And Environmental Effects On Chemical Signals Of Gryllus Rubens, Marion Davis Creech Iii, Marion Davis Creech Iii

Honors College Theses

Many animals communicate with one another in the context of reproduction, utilizing different modalities. In some cases, more than one modality is used by the sender and receiver. Each modality can provide different sets of information, or function in a different context. Importantly, no matter the modality, the signals should be clearly distinguishable between males and females and need to be reliable even in the face of environmental changes.

In field crickets, there are two major modes of communication. For long-range communication, the males produce acoustic signals to attract females. At short-range, chemical communication involving cuticular hydrocarbons (CHCs) in males …

“On Aslan’S Side”: Divine Sovereignty And Evil In The Fiction Of C. S. Lewis, Hannah Dubois

Honors College Theses

This thesis will explore C.S. Lewis’ theology of supernatural providence as depicted in Perelandra, the Silver Chair, and Till We Have Faces. Each novel involves characters who doubt the existence of divine involvement in their life. Lewis repeatedly describes the supernatural as intruding upon the mundane, closely resembling his account of encountering and converting to the Christian God. All three novels feature characters who come to doubt their sanity when in contact with spiritual beings, introducing a darker element to Lewis’ view of supernatural orchestration particularly in light of Lewis’ experience with mental illness. While fiction is an argumentative device …

Pharmacokinetics Of Cbd Supplementation In Horses: Single Dose Vs. Long-Term Feeding, Madilyn Adamchik

Honors College Theses

Research about supplemental feeding of cannabidiol (CBD) to horses is still in its early stages, but many horse owners are feeding CBD supplements for supposed benefits, including behavior and pain management. Cannabinoids work through the endocannabinoid system to modulate nervous and hormonal actions in the body, working to maintain a healthy homeostatic balance. Safety and efficacy have been tested for dosages of up to 500 mg of CBD per day for horses, but further research about the pharmacokinetics based on dosage amount and form of CBD are still needed. The objectives of this study were to evaluate the pharmacokinetics of …

Vibrational Communication Of Hebetica Sylviae, Jenna Howard

Honors College Theses

There are many different modalities animals use to communicate. Substrate-borne vibrational communication is one that is in the infancy of research, but widely used by many members of the animal kingdom. The systems by which one species of treehopper, Hebetica sylviae, utilizes vibrational communication has yet to be described due to the recent nature of its discovery. This study aims to answer basic, but vital, questions regarding the key vibrational signals Hebetica sylviae use for the purposes of courtship. There were several calls found to be important to the male including a long-range signal, characterized by pulse trains produced …

Finding Solace, Cassie Melcher, Cassie Victoria Melcher

B.F.A. Practicum Exhibition (ART 498)

In a world filled with heavy overwhelmingness, the creatures I sculpt help root myself and the viewer in a lighter, gentler place. The creatures have diverse body shapes and sizes, colors, and an exploration of pattern and texture with a focus on tactility. I want viewers to feel compelled to touch or engage personally with my sculptures, and for the creatures to live through the viewers by interacting with them or their environment. This brings moments of curiosity, self-acceptance, or compassion. Though we are often overburdened with negative thoughts, our inner critics speaking louder than anyone in the room, my …

The Essence Of Introspection, Skyler Pointer

B.A./B.S. Practicum Group Exhibit (ART 499)

In my youth, I grew up watching cartoons and I mean a lot of them. Animation has always been very important to me as I am fascinated by how we give characters movement and how it gives them a personality. Some people might look at these characters and see more than what others see in the sense that a viewer could assume how these characters are supposed to act based on how they walk or how their arms move. The storytelling that we can do with these characters gives us almost unlimited possibilities with where we can go within this …

Analyzing Post-Fledging Movements, Survival, And Space Use Of First-Year Black Vultures (Coragyps Atratus) In Kentucky, Philip Kavouriaris, Andrea Darracq

Steeplechase: An ORCA Student Journal

The time span between a fledgling’s first flight from the nest and dispersal from its natal area is known as the post-fledging dependence period. This period is a critical life stage because it affects an individual’s survival and recruitment into adult populations. In Black Vultures, young birds learn to navigate their environment but remain dependent on their parents for food during this prolonged period. We analyzed movement data from nine fledglings equipped with backpack-mounted solar-powered transmitters (GPS/GSM 20-70 PTT, 45g, Microwave Telemetry, Inc.), which included over 450,000 locations collected over a period of approximately 250 days. Home range sizes and …

Adaptive Plasticity Of Coloration In Response To Environmental Change, Karissa Coffield

Scholars Week

When rapid environmental changes occur, different selective forces can create phenotypic trade-offs in which a trait can provide fitness benefits or costs under different environmental conditions. Amphibians are particularly vulnerable to environmental change, and previous research has revealed that some species will plastically respond to variation in temperature and ultra-violet radiation (UVR) by altering their coloration. Divergent selection on coloration may change with elevation and climate induced shifts in temperature because high temperatures are likely to result in lighter color morphs but as elevation increases, UVR exposure increases leading to the prediction that darker color morphs will be more common. …

Silver Carp Hypophthalmichthys Molitrix Movements In The Lower Cumberland And Lower Tennessee River, Miranda Belanger

Scholars Week

Silver Carp Hypophthalmichthys molitrix are an invasive species making up a large portion of the fish biomass in the lower portions of the Tennessee River and the Cumberland River. This species is expanding its range throughout the upper portions of these rivers, beginning with Kentucky Lake and Lake Barkley. Silver Carp rarely spawn in Kentucky Lake and Lake Barkley, but they can enter these reservoirs through the lock chamber. Thus, the bottleneck created by lock chambers can be used to control expansion of invasive Silver Carp. Although Silver Carp movement patterns have been studied in other portions of the Tennessee …

Characterization Of The Principal And Secondary Islets During Pancreatic Development In Zebrafish With A Crispr-Mediated Glis3 Knockout, Caleb Harsin

Honors College Theses

The Krüppel-like transcription factor, Gli-similar 3 (Glis3) has been implicated in several human pathologies including neonatal diabetes, congenital hypothyroidism, and polycystic kidney disease. Numerous genome-wide association studies (GWAS) have additionally identified Glis3 as a risk locus for the development of both type 1 and type 2 diabetes mellitus. Our previous data suggest possible roles for Glis3 in endocrine pancreas specification in mice, but despite its clinical significance, much remains unknown about the role(s) Glis3 plays during development. To elucidate Glis3 gene function, a CRISPR-mediated knockout line of zebrafish was developed by deleting a segment of the Glis3 coding region …

Pharmacokinetics Of Single Feeding Of Cannabidiol In Cattle: A Pilot Study, Haley Cornette

Honors College Theses

Cannabidiol (CBD) is a substance that has been used in complementary medicine for many years. However, modern medicine has little knowledge of how this substance is utilized and metabolized in ruminant animals. Regulations on quality assurance and use in animals are lacking, and CBD supplementation in livestock is not approved. If CBD supplements can be shown to be safe and effective, detection in the animal will be important for determining regulation of use. A withdrawal period can then be established to allow time for deterioration of product to safe levels before livestock products enter human markets. This study sought to …

"Barriers Between Client Education/Communication And Exotic Animal Husbandry", Caileigh M. Linton

Honors College Theses

The purpose of this study is to quantify the knowledge gap between clientele and veterinary staff about exotic animal husbandry corresponding to housing and diet specifically. With the rise of social media platforms and influencers, the spread of misinformation and stigma revolving around the mistrust of veterinary staff has created strife between clients and veterinary professionals. Misinformation influences pet owners to implement aspects of care into their pets lives that may be unnecessary or harmful. Consequently, as veterinary professionals attempt to educate their clients they are not always trusting of the information being provided to them. This can lead to …

Using Music And Storytelling As Strategies For Conservation Education, Frances Hincks

Honors College Theses

Given the frequently negative effects each person imposes on their environment (e.g., resource consumption, use of private and public land, and waste production), the public needs to be included in conservation messaging to sustain a healthy, functioning planet. People are generally not informed about conservation topics, which creates difficulties in creating a conservation mindset. Moreover, there is a disconnect between conservation research and presenting conservation related topics to the public in a coherent, accessible format. Thus, conservation education messaging strategies need to be evaluated to determine which are most effective. The objective of this research was to determine the effectiveness …

Seroprevalence And Titer Concentration Testing For Leptospirosis In Equine, Ashley Himmelsbaugh

Posters-at-the-Capitol

The most common best management practice used to combat diseases in horses is vaccination, which can decrease the incidence or severity of illness. However, the duration of immunity will vary for each vaccination and must be considered for revaccination purposes. Titer concentration, which evaluates antibodies in the blood, may be a helpful way of determining how long an animal has immunity to a disease. Leptospirosis, a zoonotic, bacterial disease, can result in uveitis, potentially leading to blindness, and abortion in mares. One serovar, Leptospirosis pomona (L. pomona), is associated with most cases of clinical disease in horses in North America. …

Pharmacokinetics Of Cbd Supplementation In Horses: Single Dose Vs. Long-Term Feeding, Madilyn Adamchik

Posters-at-the-Capitol

Research about supplemental feeding of cannabidiol (CBD) to horses is still in its early stages, but owners are feeding CBD to relieve pain and calm behavioral issues. Cannabinoids work through the endocannabinoid system to modulate nervous and hormonal actions in the body. The objectives of this study were to evaluate the pharmacokinetics of single dose versus long-term feeding of a pelleted CBD supplement. In Project 1, eighteen Quarter Horse geldings were given a single dose of 50 mg (n=6), 100 mg (n=6), or 250 mg (n=6) of pelleted CBD. Blood samples were collected before treatment (0 hrs), and at 0.5, …
