Insecta Mundi

Anisobas Wesmael (Hymenoptera: Ichneumonidae: Ichneumoninae: Ichneumonini) is a moderately diverse parasitoid wasp genus present in the Holarctic and Indo-Malaysian regions. Here, we advance taxonomic knowledge of western Nearctic Anisobas by documenting new rearing and distribution records for A. coloradensis (Cresson) and describe A. irwini Claridge, new species, from central Arizona. There are now seven known Nearctic Anisobas species.

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 …

What Is Climate Smart Agriculture? : A Standardized Framework For Assessing The Effectiveness Of Climate Smart Agriculture Systems And Practices, Olivia G. Messerges, Trenton W. Ford

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

The United States agricultural system is challenged with feeding a growing population, adapting to climate change, and minimizing environmental damage. In response to these challenges, the paradigm of climate-smart agriculture (CSA) was developed to describe practices that address these challenges as a comprehensive strategy to address climate change and increase food security.

Definitions of CSA vary, but surround three main pillars: increasing productivity, enhancing adaptation, and reducing emissions. However, no standardized framework exists to assess if practices or technologies identified as "climate-smart" produce the desired benefits. A standardized framework would enable producers, policymakers, and researchers to improve CSA implementation, policy …

Illustrating Identity: Ethel Reed’S Art Posters And Women's Claims To Public Space In Fin-De-Siècle Boston, Miranda R. Knofczynski

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

Much scholarship has uncovered the history of women illustrators during the late nineteenth century. The rebuilding of these lost histories calls for research which theorizes women’s contributions to the burgeoning arts scene of the fin-de-siècle. This thesis will examine the posters Ethel Reed created for different companies during the height of the 1890s poster craze and discuss how she articulated women in public space in them. Reed’s art offers an aestheticized yet feminist visualization of women engaging in leisure activities such as exploring the city, reading, or attending the theatre. Many have described the women in her posters as merely …

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 …

Investigating Fatty Acid Influence On West Nile Virus In Mosquitoes And Birds, Hayley Moree

Honors Program: Senior Projects (Public)

Vector-borne diseases, including Zika virus (ZIKV), Dengue virus (DENV), and West Nile virus (WNV), pose considerable global health threats, accounting for over 400 million infections and more than 700,000 deaths annually. Many vector-borne diseases are within the Flaviviridae family. Despite this, effective treatments have not been found for some flaviviruses. Flaviviruses exploit host cellular machinery to facilitate their replication and survival, reprogramming metabolic pathways, including lipid metabolism. Lipids play essential roles in the viral life cycle, providing structural components for the viral envelope, enabling membrane rearrangements for replication complexes, and supplying energy resources necessary for particle assembly.

Targeting lipid metabolism …

Novel Chloroviruses With Unique Glycans On Their Major Capsid Proteins, Cayden J. Homolka

Honors Program: Senior Projects (Public)

Chloroviruses, of the family Phycodnaviridae, are large, dsDNA viruses with a genome of 290 to 410 kb. These virus genomes are so large that they are classified as “giant viruses”. Within this genome, up to 16 tRNAs and 330 to 450 proteins are encoded. Among the massive amounts of genes and proteins are unique carbohydrate synthesis/metabolism genes, which are responsible for the glycosylation of chloroviruses major capsid proteins. In most viruses, these proteins are glycosylated by the host enzymes located in the endoplasmic reticulum. Instead, Chloroviruses encode their own glycosylation machinery; essentially decorating themselves. Furthermore, these chlorovirus glycans are unlike …

Recognizing Injustice, Reclaiming Voices: Establishing A Missing Persons Database For Missing And Murdered Indigenous Women And Children In Nebraska, Bayly W. Watson

Department of Anthropology: Theses and Student Research

Indigenous people have been the victims of harsh persecution since the time of colonization; this has negatively impacted Native communities and has contributed significantly to the ongoing crisis of Missing and Murdered Indigenous Women and Children (MMIWC) across the United States and Canada. Under Legislative Bill 154, Richards et al. (2021) conducted an initial study to identify missing Native cases in Nebraska and in 2023, the Attorney General appointed a Missing and Murdered Indigenous People (MMIP) Liaison to help combat the number of missing Indigenous in the state. This thesis contributes to previous research by analyzing 20,049 reports from three …

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 …

Comparative Analysis Of Gunshot Trauma And Decomposition In Southeast Nebraska, Alexandra C. Tieken

Department of Anthropology: Theses and Student Research

Accurately identifying gunshot trauma (GST) in forensic anthropology remains a significant challenge, particularly in distinguishing the effects it has on decomposition. This study investigates how different types of gunshot trauma influence the rate and characteristics of decomposition in a humid continental climate, specifically southeastern Nebraska. Utilizing Sus scrofa domesticus (domestic pigs) as human proxies, four pigs were euthanized by professionals and subjected to controlled conditions at the Reller Prairie Field Station. Three pigs were inflicted postmortem with close-range gunshot trauma using a 9mm handgun, a 12-gauge shotgun, and an AR-15 rifle, while a fourth served as a trauma-free control. For …

Wildfire And Decomposition: A Taphonomic Analysis Of Thermal Alterations And Decomposition, Ashley Novak

Department of Anthropology: Theses and Student Research

Within the field of forensic anthropology, practitioners may be faced with remains that have been thermally altered by thermal alterations caused by wildfire. Within the field, very little research has been conducted examining how these thermal events impact rates of decomposition. While research has been conducted generally on the effects of thermal alteration on decomposition, these studies do not look through this lens and provide answers to the question of how do thermal alterations caused by wildfires affect rates of decomposition? This research examines the effects of thermal alteration caused by wildfire on the rate of decomposition. A decompositional study …

Firearm Trauma Across Time: Investigating Civil War Gunshot Trauma And Their Impact On Modern Forensic Analysis, Morgan K. Reeder

Department of Anthropology: Theses and Student Research

This thesis will examine the ballistic trauma caused by Civil War-era firearms and ammunition. These weapons, each with distinct characteristics, had a profound impact on the nature of combat and the resulting injuries. By investigating how these firearms’ ammunition interacted with human bone structure, this research will offer a detailed analysis of the trauma these weapons produced.

This research intends to answer several key research questions. First, how did the different types of Civil War firearms affect skeletal remains? Second, what are the key characteristics of gunshot trauma caused by these firearms in terms of bone fracturing and fragmentation, and …

Trends In Dna Aanalysis To Determine Postmortem Interval: A Systematic Lilterature Review, Victoria S. Kashkin

Department of Anthropology: Theses and Student Research

Forensic taphonomy is a recently popular field within forensic anthropology with limited research in the Central Great Plains. Given decomposition varies by region, more studies must be done to understand aspects of decomposition in this region. However, it is one of the most important subfields of forensic anthropology since determining postmortem interval (PMI) is extremely important to successfully identifying a missing individual if other indications of who the individual is are nonexistent. In this study, a systematic literature review was conducted to answer what trends are seen in research being done for using DNA to determine PMI, and what methods …

Mitigating Nitrogen Losses: The Role Of Enhanced Efficiency Fertilizers In Sustainable Corn Production, Dipesh Giri

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

Nitrogen (N) is essential for crop production, but its inefficient use often leads to environmental losses through nitrate leaching, ammonia volatilization, and nitrous oxide (N₂O) emissions. Enhanced efficiency fertilizers (EEFs), such as nitrification inhibitors (NIs) and urease inhibitors (UIs), have been developed to minimize these losses and improve nitrogen use efficiency (NUE). This research combined a multi-year field experiment and a controlled laboratory study to evaluate how dual-inhibitor fertilizers compare to conventional urea and single-inhibitor formulations in Nebraska cropping systems. The main objective was to understand how nitrogen inhibitors influence N availability, crop performance, and nitrogen losses across different environmental …

Improving Nitrogen Management And Corn Productivity Through Enhanced Efficiency Fertilizer And Cover Crop Integration In Nebraska Cropping Systems, Madhusudhan Adhikari

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

Effective nitrogen (N) management is vital for sustaining corn yield and reducing environmental impacts in Nebraska cropping systems. Three field studies were conducted to evaluate the impact of 1) fertilizer type (anhydrous ammonia [AA] with nitrification inhibitor: enhanced efficiency fertilizer [EEF] or AA without EEF) and N application timing (pre-plant vs. split with side-dress UAN) on in-season soil N availability, crop response, nitrous oxide (N₂O) emissions, residual soil N and N use efficiencies (NUEs); 2) winter cover crop (CC) species and crop rotation variability on CC biomass production, N uptake, soil N dynamics, and cash crop performance in …

Extending Cover Crop Growing Window To Improve The Health Of Environmentally Sensitive Soils, Noshin Ara Tunazzina

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

Sloping and sandy soils are highly susceptible to degradation. The health of these soils could be improved with cover crops (CCs). However, CC effectiveness in improving soil health mainly depends on CC biomass production, which is often low in temperate regions. The question is: how can we increase CC biomass production? Lengthening the CC growing window can be a potential strategy. This study assessed how 1) interseeded and terminated early (2-3 weeks before crop planting) CC, 2) interseeded and terminated late (at crop planting) CC, 3) drilled (after harvest) and terminated early CC, 4) drilled and terminated late CC, and …

Evaluating Risk And Return Of Corn And Soybean Marketing Strategies Using Monte Carlo Simulation Methods, Johanna Ilves

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This study evaluates the performance of pre-harvest marketing strategies for corn and soybeans, using Monte Carlo simulation techniques. Given the increasing volatility in commodity prices and the evolving landscape of agricultural markets, producers face growing challenges in developing effective marketing plans that manage risk and enhance profitability. This thesis examines thirteen marketing strategies from 2008 to 2024, including benchmark harvest-only sales and various pre-harvest futures contract approaches. Historical futures price data for December corn and November soybean contracts were used to simulate 1,000 marketing outcomes per strategy per year, capturing a broad range of market conditions. Key performance indicators such …

Treading Lightly: The Ethics Of Instructor Il/Legibility And Neutrality In The Classroom, Marcus A. Woodman

Department of English: Dissertations, Theses, and Student Research

Instructors in the classroom often describe their experiences teaching as being a performance, which often combines authenticity with boundaries to keep certain aspects of the instructor’s life out of the classroom. For queer instructors, their performance may be especially complicated; since queer identity is less visible than other types of identities, instructors must also weigh whether or not to come out to their students. In our current political moment, where queerness has yet again become a scrutinized topic (especially when in proximity to youth), teachers have an even more difficult decision to make.

This thesis uses queer theory and queer …

Walleye And Sauger Movement And Entrainment In Lewis And Clark Lake, William Joseph Radigan

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

Walleye Sander vitreus and Sauger Sander canadensis are both socioeconomically important sportfish species in Lewis and Clark Lake, an interjurisdictionally managed mainstem Missouri River reservoir fishery. Since 2011, adult catch per unit effort (CPUE) of both Walleye and Sauger has remained at approximately 50% of pre-2011 levels. A presumed reason for the suppressed CPUE of adult Walleye and Sauger is substantial entrainment of larval and adult fish resulting from the reservoir’s high turnover rate (7.2 d). Acoustic telemetry was used to quantify adult movement and entrainment and ichthyoplankton trawls were used to assess larval entrainment. Relative importance of factors driving …

“As If The Devil Was In Her”: Fanny Fern’S Remaking Of Authorship In The Nineteenth Century, Rowan S. Q. Havranek

Honors Program: Senior Projects (Public)

Fanny Fern revolutionized nineteenth-century literature with her unapologetically blunt and insightful commentary on social norms, education, women’s rights, and more. As a columnist for The New York Ledger, Fern challenged the conventional boundaries placed on women, blending her personal observations and experiences with sharp social critique. Because of her unflinching style and writings that addressed a wide range of topics, she became one of the most well-paid and widely read authors of her time. Yet, she was also subjected to harsh judgment. The media, particularly in the hands of her second husband, was used to damage her reputation, yet Fern …

Illustrating Insects: Using Art To Encourage Experiences In Entomology, Nia Kaufmann

Honors Program: Senior Projects (Public)

The goal of this creative project is to use art to highlight the diversity of our insect neighbors and encourage others to explore their local environments. In order to accomplish this, I created a poster-sized illustration of five insects I’ve encountered on the University of Nebraska-Lincoln’s City Campus. All insects are posted within the silhouette of Memorial Stadium, each with an ecological and personal significance. The contrast of a well-known building with less popular insects invokes the audience to reconsider how much attention they pay to the wilderness around them.

Landscape Effects On The Beneficial Arthropod Community In Agriculturally Dominated Environments, Hannah E. Stowe

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

Ecosystem services in agriculturally dominated regions rely, at least in part, on arthropods. Environment and biodiversity influence beneficial arthropods in population size, community structure, diversity, and ecosystem service provisioning. Predation is among the most important services provided by arthropods in agroecosystems. Understanding what alters predation and predator activity can support the successful application of biological control and, more broadly, integrated pest management. Land use and edge adjacency, field characteristics, landscape, seasonality, and diel period all alter predatory behavior. Crop fields dominate Nebraska agroecosystems, although interspersed perennial grasslands persist through the Conservation Reserve Program (CRP). Such grasslands supply crucial resources and …

A Case Study On Readiness Of Engineers In Agricultural Technology Start-Ups, Katie Marie Mowat

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

This dissertation explores the perceptions of practicing engineers regarding the skills necessary to be workforce-ready at agricultural technology (ag-tech) start-ups in the Midwestern United States. A qualitative case study methodology is leveraged, combining both interview and job description data. Given their uniqueness, the study divides the ag-tech start-up industry into two subcases: livestock and cropping systems. The Work Readiness Integrated Competence Model (WRICM) is used as the theoretical framework for this study and informs the conceptual framework and analysis processes. The study identified skills that fit into thirteen distinct categories, which are further grouped into four overarching resource groups. Skills …

Gene Editing Approaches To Improving Grain Amino Acid Profiles In Maize And Sorghum, Joseph Preston Hurst

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

Maize grain is deficient in lysine. While the opaque2 mutation increases grain lysine, o2 is a transcription factor that regulates a wide network of genes beyond zeins, which leads to pleiotropic and often negative effects. Additionally, the drastic reduction in 19kDa and 22kDa alpha-zeins causes a floury kernel, unsuitable for agricultural use. Sorghum, closely related to maize, has a similar lack of lysine that can be corrected with prolamin alteration and also subject to the same deleterious kernel texture. CRISPR/cas9 gives researchers the ability to directly target genes of interest. In this research, gene editing was used to specifically target …
