Meat, The Future: The Role Of Regulators In The Lab-Grown Revolution, Joseph B. DaVault, Michael S. Sinha 2025 Saint Louis University School of Law

Meat, The Future: The Role Of Regulators In The Lab-Grown Revolution, Joseph B. Davault, Michael S. Sinha

All Faculty Scholarship

The United States is one of the largest consumers of meat globally. The production of meat contributes substantially to climate change due to the levels of greenhouse gasses emitted and the amount of land, water, feed, and other natural resources required to raise animals used for meat. Traditional meat production is another major source for the emergence of zoonotic diseases and antimicrobial-resistant pathogens. Nevertheless, Americans consume more meat now than at any time in the nation’s history.

Advocates for policy change aimed at addressing the risks associated with meat production have typically focused on reducing meat consumption, alternatives to meat, …

Estimating intake requirements and creating a budget for hay purchasing is key for the effective management and profitability of equine operations. This tool can be used regardless of geographic location and will benefit a diverse audience including Extension educators, equine business owners, and horse owners.


Offering Collegiate Livestock Judging As A Student Organization, Maryfrances Miller, Don W. Edgar, Lyle Logemann 2024 New Mexico State University

Offering Collegiate Livestock Judging As A Student Organization, Maryfrances Miller, Don W. Edgar, Lyle Logemann

The Journal of Extension

Resource constraints have lowered the number of collegiate livestock judging teams, dropping the number of opportunities for collegiate judging, even though interest among students remains high. These opportunities can be provided for less expense through student-led extracurricular organizations. This approach increases the student initiative required, but also provides an increased opportunity for developing and demonstrating leadership skills.

Using Annual Forages To Replace Declining Cool-Season Grass Pasture Availability, Jonathon Jenkins 2024 University of Nebraska-Lincoln

Using Annual Forages To Replace Declining Cool-Season Grass Pasture Availability, Jonathon Jenkins

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

As land area in grain crop production increases in the US Midwest, perennial pasture availability decreases but the demand increases. Matching the seasonal growth patterns of C3 and C4 plant species to grow forages that are complementary allows producers to fill production gaps in otherwise monoculture systems and possibly increase overall productivity. One way to fill the forage production gap of C3 grass dominated pastures is by producing a warm-season, annual forage in a separate field. However, with continual reductions in land availability, this may not be an option. Using two studies, our objectives were to improve …


Effects Of Maternal Infant-Directed Sensory Cues On Early Weaned Piglet Behavior, Mattie Still 2024 University of Arkansas, Fayetteville

Effects Of Maternal Infant-Directed Sensory Cues On Early Weaned Piglet Behavior, Mattie Still

Animal Science Undergraduate Honors Theses

In the commercial pig production industry, weaning is a stressful time. Stress is related to loss in production due to increased incidence of illness, increased aggression, and reduced rate of gain, which results in economic losses for the producer. The purpose of this continuous behavior study was to explore the effects of provisional own-mother olfactory and auditory stimuli on early weaned piglet behavior and growth. During days 7-14 postpartum, the grunting of 12 individual sows was recorded while their piglets nursed. The audio files were put into a single loop with grunting occurring for 20 minutes followed by 60 minutes …


Evolution Of The Human Eye: As Compared To Other Vertebrates, Madison Queener 2024 Bowling Green State University

Evolution Of The Human Eye: As Compared To Other Vertebrates, Madison Queener

Honors Projects

There are three different types of eyes, the simple eye, the compound eye, and the camera eye (Cambridge Dictionary) (Myer-Rochow, 2014) (UCL, 2020). The retina of the eye has evolved and adapted to fit the lifestyles of the respective organisms. Because of this part of the eye, organisms are able to see different colors and use light to define the world using photoreceptors. Photoreceptors are rod cells, which are light sensitive and process light, and cone cells, which perceive the different color wavelengths, that pass visual information to the brain (Kazilek, 2010). About 5% of the photoreceptors in the retinas …


A Comparison Of The Prevalence Of Salmonella, Specifically S. Enteritidis, In Captive Born Versus Wild Caught Reptiles, Jessica Thomas, Carrie M. Doyle 2024 Bellarmine University

A Comparison Of The Prevalence Of Salmonella, Specifically S. Enteritidis, In Captive Born Versus Wild Caught Reptiles, Jessica Thomas, Carrie M. Doyle

Undergraduate Theses

Salmonella contamination and transmission is a concern in public health in the United States and around the world. It is usually transmitted to humans through contaminated poultry products, but it has also been known to be transmitted through contact with reptiles. Because reptiles are becoming more popular as pets and are known carriers for Salmonella, studies have been done to test how prevalent Salmonella is in reptiles. This study focused on testing the feces of twenty-two reptiles for Salmonella, in general, and a specific serotype of Salmonella, S. Enteritidis. This study also compared the positivity rate of reptiles born …


Grazing On The Arizona Strip: Catchment History And Repair, Melanie Heaton 2024 Utah State University

Grazing On The Arizona Strip: Catchment History And Repair, Melanie Heaton

All Current Publications

Water, not forage, is the limiting factor for wildlife and livestock grazing the Arizona Strip, a nearly 3-million-acre piece of land located north of the Grand Canyon and south of the Utah border. Since springs and groundwater are rare or absent, harvesting of natural precipitation is the main source of water for animals. Catchment systems, which capture precipitation on a sloped rubber apron and contain it in a large tank or lined pond, are used by government agencies and grazing permittees to efficiently provide water for wildlife and livestock. As catchments reach the end of their useful lives, tank replacement …


Vigilance And Foraging Behaviors Of Two Sciurid Species Between College Campuses And Urban Environments, Patrick Geyer, Zoe Buffington, Lorelei E. Patrick 2024 Fort Hays State University

Vigilance And Foraging Behaviors Of Two Sciurid Species Between College Campuses And Urban Environments, Patrick Geyer, Zoe Buffington, Lorelei E. Patrick

SACAD: John Heinrichs Scholarly and Creative Activity Days

A comparison between the extent that sciurid specimens display vigilance and foraging behaviors on college campuses against specimens within urban environments. Observations of fox squirrels and western gray squirrels were taken from the Squirrel-Net behavioral database used for this project. We found there was a significant difference between the percent vigilance behaviors and foraging behaviors on college campuses compared to urban environments. This suggests that squirrels residing on college campuses are more desensitized to pedestrian activity and foot traffic compared to squirrels that inhabit urban areas.

Physical Properties Of Odorants Affect Behavior Of Trained Detection Dogs During Close-Quarters Searches, Daniel Mejia, Lydia Burnett, Nicholas Hebdon, Peter Stevens, Alexis Shiber, Clay Cranston, Lauryn Degreeff, Lindsay D. Waldrop

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Trained detection dogs have a unique ability to find the sources of target odors in complex fluid environments. How dogs derive information about the source of an odor from an odor plume comprised of odorants with different physical properties, such as diffusivity, is currently unknown. Two volatile chemicals associated with explosive detection, ammonia (NH3, derived from ammonium nitrate-based explosives) and 2-ethyl-1-hexanol (2E1H, associated with composition C4 plastic explosives) were used to ascertain the effects of the physical properties of odorants on the search behavior and motion of trained dogs. NH3 has a diffusivity 3.6 times that of …


Impact Of Equine Interaction During Psychotherapy On Anxiety And Depression For Residential Treatment Program Patients Experiencing Substance Withdrawal, Molly M. Friend, Molly C. Nicodemus, Clay Cavinder, Caleb Lemley, Pauline Prince, Katherine A. Cagle-Holtcamp, Rebecca M. Swanson 2024 Mississippi State University

Impact Of Equine Interaction During Psychotherapy On Anxiety And Depression For Residential Treatment Program Patients Experiencing Substance Withdrawal, Molly M. Friend, Molly C. Nicodemus, Clay Cavinder, Caleb Lemley, Pauline Prince, Katherine A. Cagle-Holtcamp, Rebecca M. Swanson

People and Animals: The International Journal of Research and Practice

As incidences of substance use disorders (SUD) increase in the wake of the COVID-19 pandemic, there is a need for more effective treatment approaches. Further, treatment approaches currently available struggle to retain patients during the period of substance withdrawal in early treatment due to patients’ withdrawal symptoms including increased feelings of anxiety and depression. Withdrawal symptoms have been linked to dysregulated cortisol concentrations present in this period. Psychotherapy incorporating equine interaction (PIE) has emerged in other populations as a treatment that decreases cortisol concentrations and improves treatment retention. The present study investigated the impact of 4 weeks of PIE on …


Animal Conservation In St. Louis, Kate O'Sullivan 2024 University of Missouri, St. Louis

Animal Conservation In St. Louis, Kate O'Sullivan

Undergraduate Research Symposium

St. Louis has a multitude of organizations involved in the natural sciences. But how many of them actually contribute towards animal conservation? The St. Louis Zoo is an organization that focuses a lot of its effort on presentation, so how does that impact the funds that go towards actually saving the animals? I plan to dive into the different animal-based organizations in St. Louis and its surrounding areas, as well as discuss the positives and negatives of each organization. Furthermore, I will provide examples from several sources that I have been reviewing all year to support my claims. I plan …


Surveys Of Aphonopelma Hentzi In Missouri: Conservation Efforts Through Population, Genetics, And Habitat Studies, Anderson B. Spencer Mr., Becky Hansis-O'Niell 2024 University of Missouri-St. Louis

Surveys Of Aphonopelma Hentzi In Missouri: Conservation Efforts Through Population, Genetics, And Habitat Studies, Anderson B. Spencer Mr., Becky Hansis-O'Niell

Undergraduate Research Symposium

Aphonopelma hentzi and other tarantula species are greatly understudied organisms. In the Missouri regions there is little knowledge on their mating patterns, gene diversity, or population sizes. The focal glades in this experiment display regional fragmentation, which could prevent tarantulas from traveling and mating between regions of their glades. Due to the lack of knowledge surrounding them, methods for determining gene diversity are harmful to the organism. Our recent work has shown that it is possible to extract genetic information from the molts of burrowing tarantulas. This will allow us to safely determine the lineages and interbreeding patterns of the …


Estimation Of Probability Of Habitat Use Of Roosevelt Elk On The Olympic Peninsula, Vincent Michael Gugliotti 2024 University of Montana, Missoula

Estimation Of Probability Of Habitat Use Of Roosevelt Elk On The Olympic Peninsula, Vincent Michael Gugliotti

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Estimating the probability of habitat use for a particular species is crucial to the direct management and conservation of that species. Without knowledge of habitat preferences, managers cannot effectively focus efforts on vital resources or landscape types. However, modelling probability of habitat use can be done in several ways which leaves room for variation and uncertainty in the estimates produced by each method. This study is an examination of the variation between two estimates of probability of habitat use while focusing on a particular subspecies of elk that inhabits a unique ecosystem relative to other elk subspecies. I modeled elk …

Osteohistological Assessment Of Edmontosaurus Radii From The Liscomb Bonebed, Prince Creek Formation, North Slope, Alaska, Emma Griffin

Student Research Poster Presentations 2024

Hadrosaurs were one of the most diverse dinosaur groups in the Late Cretaceous period and are known for their numerous articulated skeletons and monodominant bonebeds (Wosik et al., 2020). They are more commonly known as duck-billed dinosaurs and are found globally including latitudinal extremes such as the artic and Antarctica. Edmontosaurus, a genus of hadrosaur, are herbivores and are very large growing up to 8,000 pounds. Edmontosaurus were known to travel in herds as a defense mechanism and were one of the last non-avian dinosaurs living during the late Campanian stage through the end of the Maastrichtian stage, right up …
