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, …

Transcription Factor Expression Landscape In Drosophila Embryonic Cell Lines, Robert A. Drewell, Daniel Klonaros, Jacqueline Dresch

Biology

Background: Transcription factor (TF) proteins are a key component of the gene regulatory networks that control cellular fates and function. TFs bind DNA regulatory elements in a sequence-specific manner and modulate target gene expression through combinatorial interactions with each other, cofactors, and chromatin-modifying proteins. Large-scale studies over the last two decades have helped shed light on the complex network of TFs that regulate development in Drosophila melanogaster. Results: Here, we present a detailed characterization of expression of all known and predicted Drosophila TFs in two well-established embryonic cell lines, Kc167 and S2 cells. Using deep coverage RNA sequencing approaches we …

Providing Proteins To Belizean Residents Through Poultry Products, Ellis Freel

Poultry Science Undergraduate Honors Theses

Belize is a food insecure, developing country. Although Belize has plenty of nutritious food in-country, the exportation of that food to generate income contributed to a distribution issue of that nutritious food. More impoverished areas of Belize do not have access to nutritious food because of the lack of affordability and high export rates. Diets with a lack of food, or lack of balanced, nutritious food can negatively impact growth and cognitive development, especially in children. Poultry is one of the only products in Belize not able to be exported. Implementing poultry into Belizean diets would affordably alleviate food insecurity …

Lavery, Kor-Jent Van Dijk, Ed Biffin, Bronwyn M. Gillanders, Jennifer Young, Pere Masque, Patricia S. Gadd, Geraldine E. Jacobsen, Atun Zawadzki, Andria Greene, Michelle Waycott

Research outputs 2022 to 2026

Anthropogenic activities are causing detrimental changes to coastal plants– namely seagrass, mangrove, and tidal marshes. Looking beyond recent times to past vegetation dynamics is critical to assess the response and resilience of an environment to change. Here, we develop a high-resolution multi-proxy approach, providing a new evidence base to decipher long-term change in coastal plant communities. Combining targeted environmental DNA analysis with chemical analysis of soils, we reconstructed 4,000 years of change at a temperate wetland on Torrens Island South Australia and identified an ecosystem shift that occurred ~ 1000 years ago. What was once a subtidal seagrass system shifted …

Effects Of Roadways On Seasonal Movement Strategies And Mate Location Success In An Imperiled Pit Viper (Crotalus Horridus), Elizabeth J. Noble

Graduate Research Showcase

A detailed understanding of animal movement behavior is fundamental to effective conservation and management. Within populations, a diversity of movement strategies can be displayed in search of critical resources, and these strategies are influenced by multiple interacting factors related to individuals and the environment. Mating partners are one critical resource that often serves as a prominent selective force shaping movement during mating seasons. For many large-bodied snakes, such as pit vipers (Viperidae: Crotalinae), male mate- searching movements are the primary determinant of mate location success. During this time, males incur significant risks associated with elevated movement. In an increasingly human- …

The Reveal: A Technical Study And Conservation Treatment Of An Overpaint Portrait, Camille Ferrer

Art Conservation Master's Projects

A severely damaged 19th-century oil painting depicting a portrait of a woman was treated at Patricia H. and E. Garman Art Conservation Department. A typed letter provided by the owner mentioned that it has been previously restored yet returned with unsatisfactory results. After further examination, the painting appeared to have been previously treated multiple times by different people. There was overpaint distinctly present on the face and later discovered to be present overall. The full state of condition of the painting was initially unknown due to the sum of the surface being overpainted. However, there were evidence of paint loss …

Microbiome Assembly And Function In The Solitary Mason Bee, Osmia Lignaria (Megachilidae), Bailey Crowley

All Graduate Theses and Dissertations, Fall 2023 to Present

Animal-microbe interactions can influence host biology, ecology, and evolution. The assembly and function of microbes found within animal hosts oftentimes depends on which species are involved. Advances in sequencing technologies have permitted the exploration of host-microbe interactions in a variety of animals, including bees. Early research aimed at understanding the microbiomes of social bees, such as honey bees and bumble bees, found that microbes prevent the spoilage of stored pollen, breakdown indigestible nutrients into smaller molecules available for uptake by the host, and also protect the host from pathogens. When environmental stressors, such as increased temperatures, disrupt the microbiome, the …

The Interactions Between Drought Tolerant Corn Hybrids And Plant Water-Stress On Weeds And Their Host Capability For Spider Mites, Mercy Adhiambo Odemba

All Graduate Theses and Dissertations, Fall 2023 to Present

With climate change, it is predicted that more frequent high temperatures and drought severity will lead to an increase in damage caused by pests that thrive under these conditions. Spider mite outbreaks, for example, are associated with plant waterstress and there is evidence that some weeds are more resilient and adapted to drought than some crops, leading to major concerns for the management of these two pest types. Weeds directly compete with crops for limited resources, but what is unclear is which weeds harbor spider mites and whether they exacerbate the impact of spider mites on corn crops under water-stressed …

Application Of Criminology In Urban Ecology And Evolution: Routine Activity Theory And Field Equipment Disappearance Dynamics, Ignacy Stadnicki, Michela Corsini, Marta Szulkin

Biology Faculty Publications and Presentations

Research in urban ecology and evolution relies on the use of deployable scientific equipment. If left unattended in the field, scientific equipment may be prone to vandalism and theft, especially in the urban space. Here, we empirically applied a theory derived from the field of criminology, specifically the Routine Activity Theory (RAT) framework, to predict disappearance rates of scientific equipment in an ongoing urban ecology research project. First, we tested a routinely applied method of equipment protection – labelling – and investigated whether equipment disappearance varied with label information content and message tone. Second, we examined whether equipment attributes (price, …

Evaluation And Improvement Of The Design 4 Every Drop Course, Kenzy Fogle

All Graduate Reports and Creative Projects, Fall 2023 to Present

Utah and the greater Intermountain West are experiencing a water crisis. Many factors are contributing to this situation, including an arid climate exacerbated by climate change, rapid population growth, and a high-water-demanding landscape typology. Landscapes currently consume an estimated 60-80% of Utah’s potable water, representing a significant opportunity for water savings. However, changing the traditional water-dependent landscape typology requires educating the public regarding water-wise landscape design processes, best practices, and implementation approaches. Utah State University is the land grant university for Utah and home to one of the oldest Landscape Architecture departments in the Intermountain West. Utah State University’s community …

Peptidomics Analysis Of In Vitro Digested Wheat Breads: Effect Of Genotype And Environment On Protein Digestibility And Release Of Celiac Disease And Wheat Allergy Related Epitopes, Mélanie Lavoignat, Angéla Juhász, Utpal Bose, Thierry Sayd, Christophe Chambon, Miguel Ribeiro, Gilberto Igrejas, Sébastien Déjean, Catherine Ravel, Emmanuelle Bancel

Research outputs 2022 to 2026

Wheat proteins can trigger immunogenic reactions due to their resistance to digestion and immunostimulatory epitopes. Here, we investigated the peptidomic map of partially digested bread samples and the fingerprint of epitope diversity from 16 wheat genotypes grown in two environmental conditions. Flour protein content and composition were characterized; gastric and jejunal peptides were quantified using LC-MS/MS, and genotypes were classified into high or low bread protein digestibility. Differences in flour protein content and peptide composition distinguish high from low digestibility genotypes in both growing environments. No common peptide signature was found between high- and low-digestible genotypes; however, the celiac or …

Establishing Marine Protected Areas In The Southern Ocean, Lessons For The Bbnj Agreement, Nengye Liu

Research Collection Yong Pung How School Of Law

This paper first gives a brief overview of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)’s struggle to establish Antarctic Marine Protected Areas (MPAs). The paper then addresses the question: what lessons can countries learn from CCAMLR's experience in establishing high seas MPAs under the Biodiversity in Areas Beyond National Jurisdiction (BBNJ) Agreement? The paper finds that the final text of the BBNJ Agreement did largely reflect CCAMLR's experience when it comes to MPAs. This is particularly so with respect to 1) clarification of the relationship between conservation and use; 2) the interpretation and application of a …

How Will Climate Change-Induced Increases In Wildfire Frequency Affect Soil Microbial Communities?, Bahar Saadaie Jahromi

Waldo Library Student Exhibits

As climate change progresses, wildfires will become more common, increasing their impact on soil microbial ecosystems. This research examines how increased fire frequency affects soil microbial communities and whether effects differ for communities associated with different tree species. Soil samples were collected from under five individuals of four tree species within each of four 1-ha plots that had experienced fire from 24 to 111 years ago. Samples were analyzed for microbial DNA using next generation sequencing techniques in order to explore the influence of fire return interval and tree species on microbial diversity and community structure. Correlations were also examined …

Prochlorococcus Death By A Ubiquitous Zooplankton Filter Feeder, Avery E. Harman

University Honors Theses

Prochlorococcus is a globally abundant cyanobacterium that can help reveal the ecology of microorganisms in the ocean. Specifically, mortality by zooplankton such as appendicularians is globally important and Prochlorococcus can help reveal some of the choices made around feeding for this ubiquitous filter feeder. Two ecotypes of Prochlorococcus were introduced to appendicularians to determine if appendicularian feed selectively between these ecotypes. Further, a single ecotype of Prochlorococcus was fed to appendicularians over a variety of life stages to determine if retention rate changed with appendicularian life stage. My results reveal that there is no significant selection between the two Prochlorococcus …

Colocalization Of Odc And Amyloid Plaques In Patients With Alzheimer’S Disease And Down Syndrome, Julia S. Gielczynski

Undergraduate Theses, Capstones, and Recitals

Polyamines, and their rate-limiting enzyme ornithine decarboxylase (ODC), are crucial for many functions in the central nervous system but levels decrease with age. In neurodegenerative diseases, like Alzheimer’s Disease (AD), polyamine levels begin to increase again. Yet, there are still many unanswered questions surrounding polyamine’s possible role in AD, especially in those with Down Syndrome (DS), who also have an extra copy of the amyloid precursor protein (APP) and tend to get AD far earlier than the general population. We aim to investigate if there is colocalization between amyloid plaques and Ornithine Decarboxylase (ODC) in patients with AD and AD/DS, …

Flower Study, Haven Hinds

Undergraduate Theses, Capstones, and Recitals

This project is a study into extinct flowers, their histories, environments, biology, colors, and assigned personalities then manifested in 3D models and a digital book. The goal was to select six flowers with interesting histories and or cultural connections. Since the flowers can, for the most part, not be seen or kept they were created in Blender as accurately as possible. To give people a means of connection with the flowers, each was assigned a personality based on different factors. These factors could be the colors they possess, where geographically they thrived, parts of their history, and biological factors. To …

Unveiling Parkinson’S: Empowering Our Community Through Awareness, Lindsay Spindler, Lorraine Wilson, Jill Jumper, Donna Walls, Annie Bane, Priscilla Wyatt, Julie St-John

CSKLS Annual Conference

Awareness about situations or conditions has brought many changes to public policy, treatment methods, and community engagement, to name just a few. Awareness also creates a culture of “seeing” people who may feel unseen or dismissed. One particular group that may feel this way are people with Parkinson’s disease. Parkinson’s disease (PD) is a progressive neurodegenerative disorder primarily resulting from a decrease in dopamine levels. This decrease in dopamine can lead to deficiencies in motor control and cognitive function that can include slow and uncoordinated movement, loss of balance, loss of smell, and decreased cognitive function¹. The implementation …
