The COVID-19 pandemic emerged during the study period and motivated …


Utah Tick Surveillance An Animated Public Service Announcement, Keith Wilson May 2022

Utah Tick Surveillance An Animated Public Service Announcement, Keith Wilson

Undergraduate Honors Capstone Projects

As the United States’ population grows, we develop more land into housing and recreate farther into wilderness areas, consequentially encountering ticks with increasing frequency. As the climate continues to change, tick population distributions are also changing, influencing our population’s exposure to tick-borne diseases. Lyme disease, a tick-borne disease named after Lyme, Connecticut, is one of the fastest growing emerging diseases in North America, and the most prevalent vector-borne infection in the United States. There are two species of tick in North America, Ixodes scapularis and Ixodes pacificus, known to be carriers of the causative agent of Lyme disease, a …


The Evolution And Unraveling Of The American Eugenics Movement, Anneka Walton May 2022

The Evolution And Unraveling Of The American Eugenics Movement, Anneka Walton

Undergraduate Honors Capstone Projects

While the evolution of American eugenics surrounding the time of Nazi Germany has been well-documented, the periods before the explosion of American eugenics and the result of the movement in the wake of the Holocaust are not so well known. Many historically-based works have described the path and growth of eugenics from the time the term was coined to the public acknowledgement of World War II and the point where Americans ended eugenic euthanasia and slowed eugenic sterilizations. There are also many works within the realm of disability history that document these events from the more common social viewpoint. This …

Factors Contributing To Bee Decline, Ann Mull, Jaydee Gunnell, Sheriden M. Hansen, Ricardo Ramirez, Andree' Walker Bravo, Cody Zesiger, Lori R. Spears

All Current Publications

Bees provide an important ecosystem service by contributing to the pollination of crop and wild plant species. Many factors have been attributed to bee declines, including habitat loss, improper apiary management, pesticide usage, climate change, pests and pathogens, competition among native and introduced bee species, poor nutrition, and other factors (Koh et al., 2016; Goulson et al., 2015; Graves et al., 2020; Soroye et al., 2020). Acting together, these factors intensify the pressure for survival beyond the adaptability of many species. This fact sheet reviews the factors contributing to decline in bee populations and what can be done to protect …

To Better Engage Students, Instructors Should Create Lab Exercises With Real-World Examples., Autumn Kelsch

Research on Capitol Hill

USU senior Autumn studies biology here in Logan and led and funded this project herself through a student grant. ‘Elementary Microbiology’ is a required course for many medical fields, and traditionally relies on several pre-determined research projects in class. However, educators suggest that students gain more from open-ended projects where the answer is unknown and the students’ findings contribute to our knowledge on the subject. When Autumn was hired as a teaching assistant for this course at USU, she developed and created a project where students look for bacteria in soil samples that may help fight infections. She now hopes …


Phosphomimetic Tyrosine Mutations In Spa47 Inhibit Type Three Secretion Atpase Activity And Shigella Virulence Phenotype, Koleton D. Hardy, Nicholas E. Dickenson Feb 2022

Phosphomimetic Tyrosine Mutations In Spa47 Inhibit Type Three Secretion Atpase Activity And Shigella Virulence Phenotype, Koleton D. Hardy, Nicholas E. Dickenson

Chemistry and Biochemistry Faculty Publications

Shigella is a highly infectious human pathogen responsible for 269 million infections and 200,000 deaths per year. Shigella virulence is absolutely reliant on the injection of effector proteins into the host cell cytoplasm via its type three secretion system (T3SS). The protein Spa47 is a T3SS ATPase whose activity is essential for the proper function of the Shigella T3SS needle-like apparatus through which effectors are secreted. A phosphoproteomics study recently found several Shigella T3SS proteins, including Spa47, to be tyrosine phosphorylated, suggesting a means of regulating Spa47 enzymatic activity, T3SS function, and overall Shigella virulence. The work presented here employs …

Human–Wildlife Interactions

The Japanese serow (Capricornis crispus; serow) is a protected territorial ungulate native to Japan. However, locally overabundant serow populations can damage forest plantations and agriculture through browsing. Despite government permitted annual culling of serows on forest lands of Gifu Prefecture, Japan, browse damage continues to be reported in hinoki cypress (Chamaecyparis obtusa; cypress) plantations. Sika deer (Cervus nippon; deer), which are co-located with serows can also browse cypress, but their impacts have never been evaluated. The objective of our research was to evaluate the involvement of each species in browse damage and to establish …

Texas Stakeholders’ Knowledge And Perceptions Of Chronic Wasting Disease Risks: Implications For Wildlife Agency Communications, Elena C. Rubino, Christopher Serenari

Human–Wildlife Interactions

Chronic wasting disease (CWD) is a fatal neurological disease impacting cervids. The disease can move swiftly through populations, making CWD management a priority for wildlife agencies across the United States. Stakeholder perceptions of CWD may shape behaviors that can negatively impact wildlife agencies. Thus, agencies need comprehensive assessments of stakeholder risk perceptions and enhanced understandings of how perceptions are formed to improve communications. Using a mail- and online-based questionnaire to collect data from September 2020 through January 2021, we surveyed 503 hunters throughout the state of Texas, USA, and 481 Texas landowners who owned property in CWD-affected counties to better …

Human–Wildlife Interactions

The management of free-roaming horses (Equus ferus) and burros (E. asinus) in the United States has been referred to as a “wicked problem” because, although there are population control options, societal values will ultimately determine what is acceptable and what is not. In the United States, free-roaming equids are managed by different types of organizations and agencies, and the landscapes that these animals inhabit vary widely in terms of access, size, topography, climate, natural resources, flora, and fauna. This landscape diversity, coupled with contemporary socioeconomic and political environments, means that adaptive management practices are needed to …

Impact Of Fish Oil On Intestinal Permeability, Inflammation, And Performance In Swine, Anthony Fernando Alberto Dec 2021

Impact Of Fish Oil On Intestinal Permeability, Inflammation, And Performance In Swine, Anthony Fernando Alberto

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Our research examined the effects of fish oil supplementation on intestinal permeability, systemic inflammation and performance in piglets. An lipopolysaccharide (LPS) challenge was done to stimulate the synthesis and release of the cytokines, in an effort to mimic the immune response that piglets would have when facing stress or pathogen challenge. Fish oil increased feed intake but did not affect growth when compared to control. Total fatty acid digestibility increased by 6% when fish oil was included in the diet. Also, we observed a 16% increase on 16-carbon fatty acids digestibility. Fish oil did not affect the plasma …

Advancing Clinical Practice Through Integration Of Congenital Cytomegalovirus (Ccmv) Testing With Newborn Hearing Screening At Mayo Clinic, Joscelyn R. K. Martin, W. Charles Huskins, Lisa A. Schimmenti, Shelagh A. Cofer, Gayla L. Poling

Journal of Early Hearing Detection and Intervention

Although cCMV is the leading non-genetic cause of childhood hearing loss in the United States, neither targeted nor universal screening protocols have been well established to identify cCMV in newborns. Moreover, until cCMV testing is universal, clinical protocols need to account for the complexities of individualized care in partnership with interprofessional care teams. This work addressed an immediate clinical practice need to identify cCMV with subsequent hearing monitoring of babies who test positive for cCMV. This effort focused on three primary objectives to: 1) define interprofessional, team-based approach to facilitate care pathways; 2) develop a clinical workflow for all babies …

Interpreting Covid-19 Deaths Among Nursing Home Residents In The Us: The Changing Role Of Facility Quality Over Time, Debasree Das Gupta, Uma Kelekar, Sidney C. Turner, Anupam A. Sule, Taya G. Jerman

Kinesiology and Health Science Faculty Publications

A report published last year by the Centers for Medicare & Medicaid Services (CMS) highlighted that COVID-19 case counts are more likely to be high in lower quality nursing homes than in higher quality ones. Since then, multiple studies have examined this association with a handful also exploring the role of facility quality in explaining resident deaths from the virus. Despite this wide interest, no previous study has investigated how the relation between quality and COVID-19 mortality among nursing home residents may have changed, if at all, over the progression of the pandemic. This understanding is indeed lacking given that …


Does Hunting Affect The Behavior Of Wild Pigs?, Oliver Keuling, Giovanna Massei Aug 2021

Does Hunting Affect The Behavior Of Wild Pigs?, Oliver Keuling, Giovanna Massei

Human–Wildlife Interactions

Wild boar and feral swine (Sus scrofa) numbers are growing worldwide. In parallel, their severe ecological and economic impacts are also increasing and include vehicle collisions, damage to crops and amenities, reduction in plant and animal abundance and richness, and transmission of diseases, the latter causing billions of U.S. dollars in losses to the livestock industry each year. Recreational hunters are the main cause of mortality for this species, and hunting has traditionally been the main method to contain populations of wild pigs. Hunting might affect the behavior of the species, which potentially can lead to these animals …

Contributors To Reduced Life Expectancy Among Native Americans In The Four Corners States, Olusola A. Omisakin, Hyojun Park, Max T. Roberts, Eric N. Reither

Sociology, Social Work and Anthropology Student Research

To assess trends in life expectancy and the contribution of specific causes of death to Native American-White longevity gaps in the Four Corners states, we used death records from the National Center for Health Statistics and population estimates from the U.S. Census Bureau from 1999–2017 to generate period life tables and decompose racial gaps in life expectancy. Native American-White life expectancy gaps narrowed between 2001 and 2012 but widened thereafter, reaching 4.92 years among males and 2.06 years among females in 2015. The life expectancy disadvantage among Native American males was primarily attributable to motor vehicle accidents (0.96 years), liver …

Human–Wildlife Interactions

Trapping of terrestrial animals is an important tool for harvest, pest control and research worldwide. To catch animals alive, animal welfare has to be ensured, which is reflected in different agreements on trading and trapping of animals between sovereign nations (Council Regulation [EEC] No 3254/91). The red fox (Vulpes vulpes) and stone marten (Martes foina) represent important predatory animals. Their influence on protected species as well as their increasing appearance in urban areas demand responsible handling. In our study, we evaluated 2 trap systems used for trapping red foxes and stone martens in accordance with criteria stipulated in the Agreement …

Alfanet: A Database Of Alfalfa-Bacterial Stem Blight Protein–Protein Interactions Revealing The Molecular Features Of The Disease-Causing Bacteria, Raghav Kataria, Rakesh Kaundal

Plants, Soils and Climate Student Research

Alfalfa has emerged as one of the most important forage crops, owing to its wide adaptation and high biomass production worldwide. In the last decade, the emergence of bacterial stem blight (caused by Pseudomonas syringae pv. syringae ALF3) in alfalfa has caused around 50% yield losses in the United States. Studies are being conducted to decipher the roles of the key genes and pathways regulating the disease, but due to the sparse knowledge about the infection mechanisms of Pseudomonas, the development of resistant cultivars is hampered. The database alfaNET is an attempt to assist researchers by providing comprehensive Pseudomonas proteome …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Citrus fruit industry in the United States has been affected during the last two decades because of the outbreak of the citrus greening disease, also known as Huanglongbing (HLB). Many people and organizations are working in therapeutics to help mitigate the impact of this disease, unfortunately there is not a cure yet. There are many mechanisms that needs to be understood about this disease, especially at the molecular level. Not only HLB, but many other infectious diseases are controlled by the interaction of proteins from the host (Citrus in this case) and from the pathogen that causes the disease. …


Retelling Mecca: Shifting Narratives Of Sacred Spaces In Volga-Ural Muslim Hajj Accounts, 1699–1945, Danielle Ross Jul 2021

Retelling Mecca: Shifting Narratives Of Sacred Spaces In Volga-Ural Muslim Hajj Accounts, 1699–1945, Danielle Ross

History Faculty Publications

This article examines how Volga-Ural Muslims narrated their encounters with the sacred spaces visited during the hajj. It examines nine accounts hajj composed from the 1690s to the 1940s, to consider how changes in international politics, Russia’s domestic politics, and the culture of Islamic learning within the Volga-Ural Muslim community led to writers to revise narratives of why the sacred spaces of Mecca were sacred, how best to experience the power of these sacred spaces, and how these sacred spaces fit into the local culture of Volga-Ural Islam under Russian and Soviet rule.

Intensive Hunting Pressure Changes Local Distribution Of Wild Boar, Jakub Drimaj, Jiří Kamler, Radim Plhal, Přemysl Janata, Zdeněk Adamec, Miloslav Homolka

Human–Wildlife Interactions

Wild boar (Sus scrofa) is now an important species of wild ungulates in Central Europe. Next to conflicts of wild boar with agriculture, the main threat of wild boar presence lies in the expansion of African swine fever across Europe. The regulation of the wild boar population is complicated by the high reproduction rate and intelligent behavior of the species, which limits hunting effectiveness. We analyzed the spatial behavior of wild boar in an environment with a lack of natural food resources. The study area consisted of a forest complex (1,283 ha) with 2 areas. In the “risk” …

Temporal Trends And Drivers Of Mountain Lion Depredation In California, Usa, Justin A. Dellinger, Daniel K. Macon, Jaime L. Rudd, Deana L. Clifford, Steven G. Torres

Human–Wildlife Interactions

Increasing human populations and expanding development across the globe necessitate continual progress in understanding and mitigating human–wildlife conflict. California, USA has the largest human population and at least half of the state is suitable mountain lion (Puma concolor) habitat. The juxtaposition of high human abundance within and adjacent to mountain lion habitat make California relevant for understanding human–large carnivore conflict. We compiled 7,719 confirmed incidents of mountain lions depredating domestic animals over a 48-year period (1972–2019) to examine temporal trends in mountain lion depredations as well as factors influencing annual depredation rates at the county level. Linear regressions …

Resilient Pedagogy

When venturing into wild or unknown territory such as a swiftly moving and ever-changing mountain river, a raft may be a necessary tool for basic survival. But what if during the careful navigation of rapid currents around rocks and other obstacles, you discover that your buoyant and flexible tool helps you to float through the fast and turbulent waters in a way that is meaningful, awe-inspiring, and exciting? As COVID-19 first hit our campuses, many of us switched to emergency remote education as a survival raft, just trying to stay afloat long enough to get to the other side of …


Sickness Behaviors Across Vertebrate Taxa: Proximate And Ultimate Mechanisms, Patricia C. Lopes, Susannah S. French, Douglas C. Woodhams, Sandra A. Binning May 2021

Sickness Behaviors Across Vertebrate Taxa: Proximate And Ultimate Mechanisms, Patricia C. Lopes, Susannah S. French, Douglas C. Woodhams, Sandra A. Binning

Biology Faculty Publications

There is nothing like a pandemic to get the world thinking about how infectious diseases affect individual behavior. In this respect, sick animals can behave in ways that are dramatically different from healthy animals: altered social interactions and changes to patterns of eating and drinking are all hallmarks of sickness. As a result, behavioral changes associated with inflammatory responses (i.e. sickness behaviors) have important implications for disease spread by affecting contacts with others and with common resources, including water and/or sleeping sites. In this Review, we summarize the behavioral modifications, including changes to thermoregulatory behaviors, known to occur in vertebrates …


Bighorn Sheep Demographics Following Pneumonia Die-Off Events, Kylie Sinclair May 2021

Bighorn Sheep Demographics Following Pneumonia Die-Off Events, Kylie Sinclair

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bighorn sheep populations across the Intermountain West are subject to disease pressure from the respiratory bacteria Mycoplasma ovipneumoniae. Although the effects of M. ovipneumoniae-associated disease die-offs are well documented, less is known about the factors driving long-term differences in post-die-off population responses. While many herds experience years to decades in which recruitment is less than 20 lambs per 100 ewes, some herds’ lamb survival rates are able to rebound rapidly following die-off events. The reason why these herds recover quickly while others do not is currently unknown. Here, we assess the roles environmental, demographic, and pathogen-associated factors could …


Efficacy Of A Yfv-Specific Monoclonal Antibody In The Treatment Of Yf In A Hamster Model, Ryne Christiansen Apr 2021

Efficacy Of A Yfv-Specific Monoclonal Antibody In The Treatment Of Yf In A Hamster Model, Ryne Christiansen

Student Research Symposium

The yellow fever virus (YFV) is a flavivirus found mainly in South America and Africa. Infection may result in fever, chills, jaundice, nausea, and vomiting. Outbreaks may have up to 50% case mortality. Although Yellow Fever (YF) is a highly preventable disease through the use of an effective vaccine, there are no approved antivirals for this disease. An effective antiviral is necessary to treat infected individuals in areas where the YF vaccine was not used and an outbreak of YF occurs. In this study, female Syrian golden hamsters were infected with YFV and treated with YFV-specific monoclonal antibodies (mAbs). Weight …
