Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

This thesis presents a systematic review of viruses found in the Peromyscus leucopus rodent species in North America. Various viruses cause serious illness in humans through contact with infected rodent urine, droppings, or saliva, or inhalation of dust contaminated with the virus, with Hantavirus pulmonary syndrome (HPS) being the most severe manifestation. Therefore, studying their distribution in rodent populations can inform public health interventions to reduce the risk of transmission. Through a literature review and data analysis, this study found that studying the distribution of viruses in rodents can help identify areas where humans may be at higher risk of contracting the virus, inform public health interventions to reduce the risk of HPS transmissions, and better understand the ecology of the virus and its host species, which can, in turn, inform conservation efforts. Furthermore, monitoring the spread of viruses over time and across regions can help us better understand their epidemiology and potential for future outbreaks, which can inform surveillance and response efforts to mitigate the impact of the virus on human and animal health. Overall, this study highlights the importance of interdisciplinary approaches in addressing complex public health and conservation issues and underscores the need for continued research in this area.
The North American deer mouse, Peromyscus maniculatus, is the most widespread mammal on the continent. It is of interest to the public health sector as a known host of several viruses which are transmissible to humans and can cause illness, including the acute respiratory disease Hantavirus Pulmonary Syndrome (HPS). This paper seeks to conduct a systematic review of existing literature on virus detection in wild P. maniculatus in order to develop an understanding of virus prevalence and distribution and identify potential areas of further research. Through the analysis of 22 studies published since 2010, it was found that detection effort has been concentrated on the American West with a focus on the spread of Sin Nombre virus, the causative agent of HPS. There are significant gaps in the existing literature both geographically and in regards to the types of viruses being sampled. Moving forward, a systematic approach to widespread sampling should be developed in order to better identify and minimize potential threats to human health.
This study highlights the significance of zoonotic diseases, which make up almost 60% of infectious diseases in humans, and their origin from animals. Among mammalian viruses, primates, bats, and rodents have been identified as high-risk carriers. Within the rodent family Cricetidae, the species complex of Peromyscus eremicus, Peromyscus californicus, Peromyscus fraterculus, and Osgoodomys banderanus have been found to play a crucial role in disease transmission. These four species are phylogenetically related and share similar physical appearances and ecological niches. They have been identified as carriers of several zoonotic diseases, including Hantavirus, Arenavirus, Yersinia pestis, and Flavivirus, with a history of spread to humans. Despite their implications for public health, many of these species remain understudied. Thus, this study aims to provide a systematic review of the existing literature on these four species to summarize the findings on virus prevalence and distribution. The review shows that sampling efforts have been uneven and recent efforts have been lacking, with potential undiscovered zoonotic diseases. The concentration of sampling efforts in California and gaps in the literature are concerning, especially with changing agriculture and climate change potentially affecting rodent communities.
Through man-made structures, human interference, artificial lights at night, and electromagnetic fields we have caused animals and insects to evolve and fit these new environments. While we tail the world around us to convince ourselves, the animals also living in these environments need to adapt to survive. In this essay, I will discuss how the affects mentioned above have cause crows, moths, snails, bobcats, blackbirds, mosquitoes, elephants, diurnal animals, fireflies, dung beetles, birds and bats to evolve. The adaptations these organisms made were caused by the subtle ways in which we have impact the landscapes around us.
