Insecta Mundi

The genus Alocodesmus Silvestri, 1896 (Polydesmida: Chelodesmidae: Batodesmini) currently comprises six valid species, three of which are recorded for Colombia, including A. danielae Romero-Rincon and Alvear, new species, from Yondó, Antioquia Department. Two species are known from Panama and one from Venezuela. The new species differs from its congeners by having a spoon-shaped prefemoral process that is ventrally extended forming a conspicuous concave space with branch Z being shorter than branches X and Y. The identity of A. hanseni Silvestri, 1898, previously of uncertain status, is revised, and the species is herein proposed as a new synonymy …

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 …

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.

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 …

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.

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 …

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.

Overcoming Vaccine-Associated Enhanced Respiratory Disease In Swine Flu With Lipid Nanoparticle-Dna Technology, The Nguyen

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The two primary challenges in developing vaccines against swine influenza A virus (IAV-S) are the continuous viral evolution and vaccine-associated enhanced respiratory disease (VAERD). Current vaccine strategies share a common limitation: the significant time required for licensing updated vaccines. Moreover, the strain selection for vaccine updates depends entirely on predictions, raising the risk that chosen strains may not match circulating viruses. Such mismatches not only reduce vaccine efficacy but also risk exacerbating disease severity through VAERD. Here, in this thesis, we developed and evaluated a novel DNA-based vaccine platform designed to address the need for rapid updates in response to …

“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 …

Simulations Of Differential Reflectivity Columns In Quasi-Linear Convective Systems, Devon Jacob Healey

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

Much research over the past decade has revealed that dual-polarization radar is a powerful tool in furthering our understanding of severe storm dynamics and subsequently improving warning strategies for these hazardous events. However, there are currently very few studies examining a particularly prolific severe convective storm mode with dual-polarization radar: quasi-linear convective systems (QLCSs). These storms can occur in any season of the year throughout most of the contiguous United States and can have immense societal impacts. Warning for the hazards produced by QLCSs is currently a significant operational challenge, therefore, research is needed to see if applying dual-polarization radar …
