Advancing Butterfly Systematics Through Genomic Analysis, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Within the framework of an ongoing comparative genomic study of global butterfly diversity, we construct phylogenetic trees combining all protein-coding genes assembled from the whole genome shotgun data. When viewed in the context of current taxonomy and phenotypic knowledge, the genome-wide phylogeny points to further advances in butterfly systematics, which are presented here. We assign major clades with comparable levels of genetic divergence to the same taxonomic rank and apply criteria involving relative population divergence and gene flow to define species boundaries. As a result, one genus, 13 subgenera, 62 species, and five subspecies are proposed as new (type species …

The Connection Between An Unequitable Distribution Of Care Responsibilities And A Widening Gender Nutrition Gap In Latin America, Alexis Nicole Bodlak

Honors Program: Senior Projects (Public)

The notion of care refers to activities that satisfy the basic needs of existence and reproduction. Within rural communities, care work such as the production and preparation of food contributes to food security at the household level. Care work supports the paid workforce, allowing workers to focus on commercial productive activities that generate economic income in rural communities. Women perform 6.3 to 29.5 more hours per week than men in unpaid care work, reducing their time for income-generating activities and personal nutrition management. Affecting their economic independence and ability to access and consume nutritious food. Studies show that in food-insecure …

The Role Of Popular Culture In Decolonial Transformative Learning: A Racially Minoritized Adult Educator's Journey, Riyad Shahjahan

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

While a growing body of literature examines the role of popular culture in transformative learning, much of it centers on fostering transformative experiences among learners, rather than educators themselves. This paper addresses that gap by exploring how popular culture enhances transformative learning for racially minoritized adult educators. Drawing from my experiences as a graduate instructor at a predominantly white institution, I reflect on how engaging with popular cultural texts facilitated my own transformative learning within my teaching practice. Grounded in decolonial theory, which emphasizes the inclusion of Indigenous and marginalized knowledges while confronting contemporary colonial oppressions, my reflexive approach highlights …

Medusa's Metamorphosis: Art, Mythology, And The Changing Perception Of Female Power, Elizabeth Kehr

School of Art, Art History, and Design: Theses and Student Creative Work

The evolution of Medusa’s iconography in ancient Greek art mirrors societal and cultural transformations. As attitudes shifted in relation to gender roles, power relationships, and morality changed, so too did images of the Gorgon. Following the course of development of Medusa’s image allows one to discover details of the thoughts and struggles the ancient Greeks had with concepts of power, womanhood, and monstrosity and otherness. Previous art historical research on Medusa has largely examined her function and evolution of visual depictions from the Archaic monster to Classical ideal. Few, however, have explored how and why these changes may be indicative …

Heat Induced Diagenesis And Osteometrics: An Experimental Approach To Assessing Thermal Alterations To Forensic Anthropological Data On Dry Bone, Audrey Holbeck

Department of Anthropology: Theses and Student Research

Fire appears in forensic casework in instances of arson, vehicle fire, house fire, to conceal evidence, or, in increasing contemporary frequency, wildfire, as a result of climate change. Thermal alteration is a destructive process to osseous material and can impact the accuracy of identification methods and trauma analysis by alteration of the structure, appearance, and morphology of human remains. This study seeks to validate previous research on the metric and morphological changes bone undergoes when exposed to extreme heat, and how that may impede estimation of metric features such as stature. Three long bones, a humerus, femur, and tibia, from …

Heartbeat Of The Heartland: Sonic Engagement With Hip-Hop In The American Midwest, Lauren R. Millhorn

Department of English: Dissertations, Theses, and Student Research

This project analyzes Hip-Hop artists from the American Midwest through the context of the Midwest’s construction as a nostalgic, peaceful area where conflict seems nonexistent. This study applies Adam Ochonicky’s concept of nostalgic spatiality, or “instances in which nostalgia is projected onto a physical environment, thereby altering the perception, understanding, and/or experience of that space and its accompanying cultural sphere” (Ochonicky 29) to close readings on Midwest Hip-Hop texts. In the case of the Midwest, projected nostalgia is rooted in whiteness and propels the narrative that the Midwest is predominantly occupied by white people who maintain its peace and serenity …

Ediacaran Paleocommunity Structure, Body Size Evolution, And The Rise Of Complex Animals, Matthew Philip Craffey

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The Ediacaran period (635-538ma) is a key interval in the evolution of life as it records the first macroscopic animal communities. Major extinction pulses appear to have altered the composition of the global marine biosphere between each sub-interval of the Ediacaran Period: the Avalon, White Sea, and Nama assemblage Zones. While considerable attention has been paid to the causes of these extinction pulses, less has been afforded to the consequences of Ediacaran biotic turnover for community organization and function. Moreover, it is unclear how body size - the defining trait of macrofauna - affected the transition between animal groups across …

Influence Of Biotic And Abiotic Factors On Decomposition And The Determination Of Time Since Death: Applications Of Forensic Entomology And Taphonomy, John Oladapo Obafunwa

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The determination of the postmortem interval (PMI) is essential for the investigation and successful prosecution of suspected cases of homicide. While the forensic pathologist might be able to draw fairly accurate conclusions during the initial 24–36 hours, beyond this period, the assistance of other experts like forensic entomologists and taphonomists would be required. The present study was designed to observe the postmortem changes in Sus scrofa placed in a cage in Nebraska, located in the American Central Great Plains. The setting is in an open grassland in late spring to early summer. The observed variables with respect to biotic and …

Assessing Spatial And Temporal Variation In Photoprotective Responses Of Deciduous And Evergreen Tree Canopies With Leaf Spectroscopy, Alexander Piper

School of Natural Resources: Dissertations, Theses, and Student Research

Environmental conditions frequently prevent carbon fixation by plants, leading to the absorption of excess light that can damage photosynthetic machinery if not dissipated. To do so, plants utilize several photoprotective mechanisms, some detectable remotely using Photochemical Reflectance Index (PRI). Two components of PRI correspond to the facultative engagement of the xanthophyll cycle (ΔPRI) and constitutive changes in xanthophyll pigment pool sizes (PRI0), representing distinct mechanisms regulating shorter and longer-term photoprotection, respectively. Our understanding of interspecific and intraspecific variation in these mechanisms is limited, primarily because PRI components are often not clearly distinguished. This study aimed to assess the variation in …

Radar Precursors To Severe Weather Reports In Left-Moving Supercells, Eric A. Carothers

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

While much research has examined dual-polarimetric signatures of right-moving supercells, very little has been done with left-moving supercells. Given that left-moving supercells are thought to be disproportionate producers of large hail, understanding their internal dynamics is vitally important. This study examines differences and trends in the dual-polarimetric signatures of left-moving supercells to identify precursors to severe weather reports. A dataset of left-moving supercells associated with severe weather reports was created. These storms are processed with an automated analysis algorithm that identifies and quantifies the polarimetric signatures in each storm. A method for analysis of differences and trends in their dual-polarization …

Strategies For Reducing Racial Disparities In Maternal Health Outcomes: An Examination Of The Role Of Doulas, Samavi Rafique

Honors Program: Senior Projects (Public)

Comparatively high rates of maternal morbidity and mortality remain a significant concern in the United States, particularly for Black women, who face a risk of maternal mortality that is four times higher than that of white women. Realizing the historical context of this burden requires tracing American obstetric and gynecological medicine to its 19th-century roots, where the medical experimentation of enslaved Black women occurred largely unopposed by the voices of those in power. The legacy of this is embodied in the modern maternal health crisis, marked by stark racial disparities in maternal health outcomes. As non-clinically trained professionals whose supportive …

Belly Dance In Nebraska: Identity, Social Acceptance, And Perseverance, Alex R. Mohr

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Belly dance is an art form as well as an often-contested practice due to tensions over dress, terminology and cultural practices within the belly dance community because the dance originated outside the United States. Additionally, there is often a need to prove the legitimacy of the dance to those outside its sphere because it is often stigmatized due to the early association with exotic dancing. Belly dance is inherently geographic, as seen through its places of origin, music and movement styles, global spread, practitioners, and spaces of practice. However, it has not been well-represented in geography, and there is also …

Towards Advancing Streamflow And Peak Flow Prediction With Machine Learning: Identifying Infrastructure At Risk, Sudan Pokharel

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Due to climate change and its impact, the need for adaptive strategies for natural disaster mitigation and resource management has never been more urgent. Central to this is water resource management, which is essential for sustainable human activities, ecological balance, and the mitigation of natural hazards like floods. Streamflow is a crucial element of water resource management and plays a vital role in planning and building water infrastructure, implementing emergency response plans, supporting flood mitigation initiatives, and regulating agricultural and industrial use. However, accurate prediction of streamflow still remains a challenge due to the complex non-linear and non-stationary interaction between …

Considerations And Techniques For Producing Urban Tree Canopy Maps Using Freely Available And Accessible Methods, Hugh Reed Ellerman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Urban forests are valued as green infrastructure for the variety of benefits they provide across ecological, social, public health, and economic domains. To understand the distribution of trees, maps are required. Many methods of mapping tree cover use expensive and data-intensive datasets such as hyperspectral and LiDAR imagery, making these methods inaccessible to municipal forest managers. Variations in the modelling approaches of existing, freely available methods are not addressed in sufficient enough detail to understand the trade-offs implicit in these variations. Further, characteristics of urban tree canopy mapping (high spatial resolution imagery, heterogeneous urban environments, the importance of the tree …

Research shows that preventative measures including brushing, fluoridated water, and regular checkups are effective strategies to mitigate tooth decay. However, there appears to be a divide between rural and urban populations, as the presence of dental cavities is significantly greater in remote areas in the State of Nebraska. Research methods used in this analysis included analyzing accredited academic literature to illustrate how cavities form from a biochemical perspective. Research methods also …

Enhancing Remote Sensing Imagery Temporal Resolution Using Starfm Data Fusion Approach For Improved Land Surface Monitoring, Ahmadreza Pourghodrat

School of Computing: Dissertations, Theses, and Student Research

High-resolution remote sensing imagery plays a critical role in various domains, such as farm-level agricultural operations, environmental monitoring, and natural resource management. However, data with high spatial resolution typically have low temporal resolution, and those with high temporal resolution often lack spatial detail. For example, Landsat 8 and 9 satellites deliver high spatial resolution images with a 30-meter pixel size but suffer from low temporal resolution, with a 16-day revisit cycle. In contrast, satellites like MODIS and VIIRS provide daily images but with a much coarser spatial resolution (375 meters or more), reducing spatial details. Additionally, there is a lack …

Devising Optimized Maize Nitrogen Stress Indices In Complex Field Conditions From Uav Hyperspectral Imagery, Jiating Li, Yufeng Ge, Laila A. Puntel, Derek M. Heeren, Geng Bai, Guillermo R. Balboa, John A. Gamon, Timothy J. Arkebauer, Yeyin Shi

School of Natural Resources: Faculty Publications

Nitrogen Sufficiency Index (NSI) is an important nitrogen (N) stress indicator for precision N management. It is usually calculated using variables such as leaf chlorophyll meter readings (SPAD) and vegetation indices (VIs). However, no consensus has been reached on the most preferred variable. Additionally, conventional NSI (NSI_uni) calculation assumes N being the sole yield-limiting factor, neglecting other factors such as soil water variability. To tackle these issues, this study compared various variables for NSI calculation and evaluated two new N stress indicators in minimizing the impact of confounding water treatment. The following ground- and aerial-derived variables were compared …
