Primary Investigation Of Rice-Fish Co-Culture: Investigating The Feasibility Of Raising Fish In Flooded Rice Paddies In The Southern Usa, Yulin Jia, Aaron K. Jackson, Bartholomew Green, S. Adam Fuller, Heather Box, Laduska Sells, Candis Ray, Paxton Harper, Brennan Smith

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

With limited land and water resources available it has become critical to maximize output for agricultural products while maintaining sustainable farming practices. Ricefish co-culture can be used to maximize limited land and water resources for production of rice and fish concurrently and reduce the need of chemical inputs. While rice-fish co-culture has been practiced in Asia for centuries, very few studies have examined the feasibility and economic impact of rice fish co-culture in the U.S.A. Two studies were conducted in Stuttgart, Arkansas, U.S.A. from 2023-2024 to investigate the suitability of raising Koi carp in flooded rice paddies with a sushi …

Evaluation Of Waste Plastic Addition Via Dry Method On Asphalt Mixture Performance, Isabella Madeira Bueno

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Incorporating waste plastic (WP) into hot mix asphalt (HMA) offers a promising approach to enhance recycling rates and improve asphalt concrete (AC) performance, particularly in moisture damage resistance. However, results vary widely due to differences in WP types, sizes, and mixing methods. The lack of standardized procedures, especially for the dry process, has led to inconsistent integration and unclear roles of WP in AC mixtures. Studies suggest that introducing WP to pre-heated aggregates at temperatures exceeding its melting point can enhance mixture resistance to rutting, cracking, and moisture damage. In this context, this study was conducted in two phases to …

A Quantitative Examination Of The Sexual Health Of Aging Black Men In Rural South Africa, Esihle Lupindo

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

This dissertation uses survey data primarily from Wave 1 of the Health and Aging in Africa: Longitudinal Study of In-depth Community in South Africa (HAALSI) which was collected in 2015 to study the sexual health of Black men in rural Mpumalanga, South Africa. Broadly speaking, I examine aging men’s sexual health as it related to HIV, well-being, loneliness, social networks and disclosure. The definition that I use for sexual health was coined by MacPhail and Campbell (2001) who define it as “not only sexual practices but also what people know and believe about sex, particularly what they think is natural, …

Nebraska Farm Real Estate Market Highlights 2024-2025, Jim Jansen

Nebraska Farm Real Estate Reports

Reversing a half decade in gains, the all-land average value in Nebraska declined for the year ending February 1, 2025, averaging approximately 2% lower than the prior year. Figure 2 summarizes these figures and trends along with the percent changes over the preceding year’s all-land average for the eight districts in the state.

Rates of decline were the highest in the Northeast and Southeast Districts, as these areas averaged 3% lower for the all-land average. These Districts trended slightly similar to the state's rate of decrease of 2%. The South and Southeast District also averaged 2% lower.

The other four …

Gmos And Public Perception: College Students’ Opinions And Knowledge Of Genetic Engineering, Serene M. Cheng

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

Genetically modified organisms (GMOs) can be developed and implemented to address significant global challenges, including nutrient deficiencies, climate change, and crop disease. However, widespread opposition has prevented the success of GMOs. We believe this opposition is strongly connected to a lack of understanding about genetics in general, which has been reflected by previous studies.

In this study, we considered the relationship between GMO support and genetics knowledge by comparing results from a brief quiz and responses to prompts relating to GMOs. Using a survey of college students, we found that support for GMOs and general knowledge of genetics are positively …

A Battle Of Armies: Massive Attack Of Natural Enemies To The True Armyworm Mythimna Unipuncta (Haworth, 1809) (Lepidoptera: Noctuidae) In Forage Crops, Armando Falcon-Brindis, Raul T. Villanueva

Insecta Mundi

Understanding the interactions between plant-host-parasitoid plays a major role in insect pest management. Farmers in the southeastern United States rely on pasture systems for cattle milk and beef production, but the benefits of parasitoids and predators on major lepidopteran pests on pasture lands are still overlooked. Here, we aimed to identify and quantify the effect of parasitism on the true armyworm Mythimna unipuncta (Haworth, 1809) (Lepidoptera: Noctuidae) attacking teff grass Eragrostis tef (Zucc.) Trotter (Poaceae) and crabgrass Digitaria sanguinalis (L.) Scop. (Poaceae) in western Kentucky. In early August of 2023, 547 larvae of M. unipuncta were collected from experimental …

The Enigmatic Samuel Aughey: Nebraska’S Pastor Naturalist, Hugh H. Genoways, Margaret R. Bolick, Mary Anne Andrei

Zea E-Books Collection

Samuel Aughey at age 39 became the first Professor of Natural Science at the new University of Nebraska in Lincoln, serving from 1871 to 1883. He was an ordained pastor of the Evangelical Lutheran Church, with an addendum degree from Pennsylvania College (now Gettysburg College) in 1856 and an A.M. degree two years later. His early pastoral work was in Pennsylvania, but in 1864 he became a home missionary to a church in Dakota City, Nebraska. Aughey’s career at the university was marked with successes and honors, but also criticism and questions about his basic knowledge of the sciences. While …

Why Real Impact Stories Of Forest-Dependent Communities Are Essential In Carbon Marketing, Andrew Mwape

School of Natural Resources: Faculty Publications

As the global carbon market matures, the pressure on companies and project developers to prove the integrity and social value of their carbon offset initiatives has never been greater. At the heart of this growing scrutiny lies a key opportunity: to move beyond metrics and tell authentic, human-centered stories that reflect the real impact of carbon projects; especially those rooted in forest landscapes.

2025 Legislative Update, J. David Aiken

Cornhusker Economics

The 2025 Nebraska state Unicameral dealt with major state budget challenges but also managed to enact four bills affecting Nebraska agriculture and holding three other bills over for possible action in the 2026 legislative session. Enacted legislation dealt with a ban on laboratory-grown meat, the merger of state natural resource and environmental agencies, amending the 2024 paid sick leave initiative, and establishing a School Financing Review Commission. Agricultural-related bills carried over to the 2026 legislative session include modifying cattle feedlot brand inspection fees, inheritance tax reductions, and modifying the 2022 minimum wage initiative.

Science Communication Through Cool Critters: An Informal Learning Experience For Youth, Jamila L. Bajelan, Mary J. Harner

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

There are numerous ways to communicate science and assess the effectiveness of that communication. One approach focuses on increasing awareness, enjoyment, interest, opinion, and/or understanding of science. For this study, we created an informal learning experience for youth to communicate the science of animals in Nebraska. We developed Cool Critters, a weeklong summer camp for elementary school-aged students, to increase participants' enjoyment, interest, and opinion of Nebraska animals. In 2023, Cool Critters was led in three educational settings in central Nebraska and reached sixty-six participants. Surveys were used to determine the camp's success in effective science communication and whether …

The Current 'Ban-Demic': School Book Bans In The U.S., Barbara Perez, Jane Caputi

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This essay examines the alarming rise of U.S book. Our stance is grounded in our experiences as educators and academics in Florida, the state with the highest number of book bans and legislation that has significantly impacted education. Book bans infringe on freedom of expression, right to access information, = students’ right to education, and real harm to targeted communities (i.e., LGBTQIA+ and BIPOC communities), as the bans contribute to the ongoing marginalization and stigmatization of these communities. Diverse representation is key in literature and education. Banning popular culture texts from the classroom stifles critical thinking, social dialogue, and, ultimately, …

Foreign Aid, E. Wesley F. Peterson

Cornhusker Economics

According to a recent poll, United States adults think on average that about 26 percent of the federal government’s budget goes to foreign aid with some believing that more than half is put to that use. Public opinion surveys have returned similar results for many years with most respondents seeming to believe that this is far too generous often suggesting that something on the order of 5 percent of federal spending would be more appropriate. In fact, until recent efforts to eliminate foreign aid altogether, the actual amounts spent have represented one percent or less of the federal budget. The …

Spring Field Report, March–May 2025, W. Ross Silcock

Nebraska Bird Review

Perhaps the most important takeaway this spring is the continuing phenomenon of large numbers of species with early spring arrival dates. Although about half as many as 2024, there were 64 examples of either tied or new early arrival dates, most obviously of insectivores such as swifts, flycatchers, vireos, swallows, pipits, longspurs, and 10 warbler species. Among these, record or near-record early were Whip-poor-will, Black-necked Stilt, Marbled Godwit, Black Tern, Olive-sided Flycatcher, Purple Martin, Rock Wren, Gray Catbird in central, Spotted Towhee in north and west, and Hooded Warbler.

Following along logically perhaps with early arrival dates were a number …

The Impact Of Ai Bots And Crawlers On Open Repositories: Results Of A Coar Survey, April 2025, Kathleen Shearer, Paul Walk

Copyright, Fair Use, Scholarly Communication, etc.

There are a growing number of AI bots crawling repositories. These automated bots, or crawlers, navigate the internet, gathering data and indexing information for search engines, AI and large language models, and other purposes. While some bots are rather innocuous, others are sufficiently aggressive that they are increasingly causing service disruptions in repositories (and other scholarly communications infrastructures). To learn more about the current state and gain a better understanding about the impact of bots and crawlers on repositories, COAR distributed a survey to members in April 2025. The survey received 66 responses from repositories around the world (22 from …

“You Can Rise Back Up Again”: Using Photovoice To Understand Healing From Intimate Partner Violence Among Lgbtq+ Racial-Ethnic Minority College Students, Stephanie Lim

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

Intimate partner violence (IPV) is a longstanding public health crisis that has been linked to deleterious mental and physical health issues and negative academic outcomes among college students. Further, IPV disproportionately affects LGBTQ+ individuals and certain racial-ethnic minority students. Campus services are not adequately meeting the needs of these survivors and these efforts would be better informed by centering students disproportionately affected by IPV. Guided by intersectionality and minority stress theories, the current photovoice study examined the strengths that fostered healing and the challenges that LGBTQ+ racial-ethnic minority survivors faced in their recovery journeys. Participants were eight LGBTQ+ racial-ethnic minority …

Farmnav-Uav: A Field-Ready Autonomous Uav For Tracking Static And Dynamic Trajectories In Agricultural Applications, Veera Venkata Ram Murali Krishna Rao Muvva

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

This study presents the design and development of a custom-built uncrewed aerial vehicle (UAV) tailored for precision agriculture. Unlike commercial UAVs, which are often constrained by proprietary systems and limited hardware customization, the proposed platform emphasizes modularity, upgradeability, and cost-effectiveness. The UAV is equipped with a Cube Blue flight controller for reliable low-level actuation and a Raspberry Pi 4 companion computer that executes a Model Predictive Control (MPC) algorithm for high-level trajectory optimization and stability enhancement.

Most conventional UAV autopilot systems rely on non-optimal control strategies, such as proportional–integral–derivative (PID) controllers, which can be inadequate for dynamic or resource-constrained environments. …

Integrating High Throughput Phenotyping Approaches To Characterize Plant Traits And Support Nutrient Management Research, Katie J. Bathke

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Over the past decade, considerable research has addressed the social, economic, and agronomic challenges posed by imbalanced nutrient applications, particularly nitrogen and, more recently, sulfur. In response, high throughput plant phenotyping, as one of the latest approaches, has contributed to the development of innovative techniques for assessing key plant phenotypes under stress over time in both field and greenhouse environments. However, there is a limited number of studies applying these techniques for nutrient management, particularly in scenarios where two abiotic stressors coexist, such as the combination of water stress and nitrogen deficiency, or concurrent nitrogen and sulfur deficiencies.
