Rice Biomass Response To Various Phosphorus Fertilizers In A Phosphorus-Deficient Soil Under Simulated Furrow-Irrigation, Jonathan B. Brye, Kristofor R. Brye, Diego Della Lunga

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis (SAT) and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of thyroid glands with mononuclear immune cells resulting in the destruction of thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies described immune cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various immune cells infiltrating the thyroids have not been well defined. In this project, frozen and stored thyroid glands that were previously collected at 1, 4, 7, 14, …

Investigating The Potential For Industrial Dairy Farms To Move Towards Sustainability In Western Michigan, Kendra Kay Slater, Rebecca Williams

Student Summer Scholars Manuscripts

Industrial dairy farms, also referred to as concentrated animal feeding operations (CAFOS) or factory farms, are often known for the negative effects they have on the environment and animals. However, these farms are the backbone of our food systems supplying 99% of our dairy and meat in the United States. In this qualitative case study, we conduct in-depth interviews and farm transect walks with five industrial dairy farmers in Western Michigan to examine how they view and define sustainability, how they incorporate sustainable practices on their farms, and what they perceive as the barriers to industrial dairy sustainability. To analyze …

Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Typical blackberries (Rubus subgenus Rubus) have perennial crowns and roots and biennial canes. The first-year canes (primocanes) are usually vegetative, while second-year canes (floricanes) produce fruit. Primocane-fruiting blackberries produce fruit on first-year canes and are desirable to growers because they potentially allow for a longer harvest season in temperate regions and enable production in tropical areas where no natural chill hours are accumulated. The development of molecular markers for desirable traits can potentially increase efficiency in blackberry breeding. However, to date, there are no diagnostic molecular markers for economically important traits in blackberries. Primocane-fruiting is recessively inherited, and tetraploid blackberries …

An Inclusive Playground For Infant And Toddler Development, Amanda M. Swartz, Jacquelyn D. Wiersma-Mosley, Donia Timby, Shelley Mcnally, Caitlyn Daniel

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The purpose of this project was to help children reach more developmental goals and to make outdoor play at the Jean Tyson Child Development Study Center more inclusive for all children. Children gain many developmental goals from playing outside and being exposed to other environments as compared to just being inside the classroom. Outdoor play should be as inclusive as indoor play and offer many different activities and outlets, just as the indoor classroom does. The implementation of this service-learning creative project was to add more versatility to the outdoor area at the University of Arkansas Jean Tyson Child Development …

Teaching Agroecology: Preparing Students For Navigating Uncharted Territory, Charles A. Francis, Steve Gliessman

Department of Agronomy and Horticulture: Faculty Publications

Agroecologists understand that farming and food systems are more complex than the aggregation of their components. This realization drives our choices of learning strategies and activities that will prepare students for complexity and uncertainty. Our quest for a just, sustainable, and nutritious food system adequate to equitably serve everyone on the planet today and into the future is an enormous challenge. An undertaking of this magnitude will be met only with major adjustments informed by thoughtful teaching and practicing problem solving skills through a new educational lens. The principles of agroecology help us focus this lens on the wicked problems …

Experiences With Covid-19 Stress Among Hispanic/Latino Farmworkers, Brenda Berumen-Flucker, Hadiza Galadima, Sylvia Shangani, Michele Kekeh, Muge Akpinar-Elci

Community & Environmental Health Faculty Publications

BACKGROUND: Hispanics/Latinos, particularly those that identify as foreign-born, are overrepresented in the agricultural sector in the U.S. Over the course of the COVID-19 pandemic, this subpopulation of farmworkers was recognized as an invaluable group of essential workers unable to implement COVID-19 protections.

METHODS: Previously validated COVID-19 stress scale measures were identified, adapted, and translated to collect COVID-19 stress data from Hispanic/Latino agricultural workers in two heavily agricultural counties in northeastern North Carolina. Participants were recruited using purposive convenience sampling. Data collection took place from June to November of 2021.

RESULTS: The majority of Hispanic/Latino agricultural workers surveyed reported experiencing worries …

United We Stand? Investigating The Impact Of Unified Dues Agreements Between State And National Career & Technical Education (Cte) Professional Organizations On Cte Funding In The Southern States, Justin Ryan Hall

Theses and Dissertations

Career and Technical Education (CTE) teachers have long been active in lobbying the federal and state governments in support of CTE through their professional organizations, but these are not traditionally considered interest groups. This study sought to determine if the formal relationships—dues agreements—between the two largest national professional organizations, and their state affiliates had an impact on state funding for CTE. The impacts of professional organization unity, membership rates, and lobbying expenses on state-level CTE funding were analyzed through the lens of interest group theory, a subfield of political science. Within this population (N = 13), 1) a link …

Patterns Of Population Structure And Introgression Among Recently Differentiated Drosophila Melanogaster Populations, Jenn M. Coughlan, Andrius J. Dagilis, Antonio Serrato-Capuchina, Hope Elias, David Peede, Kristin Isbell, Dean M. Castillo, Brandon S. Cooper, Daniel R. Matute

Nebraska Cooperative Extension: Faculty and Staff Publications

Despite a century of genetic analysis, the evolutionary processes that have generated the patterns of exceptional genetic and phenotypic variation in the model organism Drosophila melanogaster remains poorly understood. In particular, how genetic variation is partitioned within its putative ancestral range in Southern Africa remains unresolved. Here, we study patterns of population genetic structure, admixture, and the spatial structuring of candidate incompatibility alleles across a global sample, including 223 new accessions, predominantly from remote regions in Southern Africa. We identify nine major ancestries, six that primarily occur in Africa and one that has not been previously described. We find evidence …

This qualitative study aimed to understand the actions, challenges, and lessons learned for addressing the food and water needs of flood survivors, with a special focus on vulnerable populations and the implications for food security, to inform future disaster response efforts in the U.S. Semi-structured in-depth interviews were conducted from January to August 2020 with the local, state, and national stakeholders (n = 27) involved in the disaster response to the 2019 Nebraska floods, particularly those involved in providing mass care, such as food, water, and shelter, for the flood survivors. The challenge themes were related to limited risk …

Hybrid Incompatibility Between Ldrosophila Virilis And D. Lummei Is Stronger In The Presence Of Transposable Elements, Dean M. Castillo, Leonie C. Moyle

Nebraska Cooperative Extension: Faculty and Staff Publications

Mismatches between parental genomes in selfish elements are frequently hypothesized to underlie hybrid dysfunction and drive speciation. However, because the genetic basis of most hybrid incompatibilities is unknown, testing the contribution of selfish elements to reproductive isolation is difficult. Here, we evaluated the role of transposable elements (TEs) in hybrid incompatibilities between Drosophila virilis and D. lummei by experimentally comparing hybrid incompatibility in a cross where active TEs are present in D. virilis (TE+) and absent in D. lummei, to a cross where these TEs are absent from both D. virilis (TE−) and D. lummei genotypes. Using genomic data, …

An Analysis Of Decolonization Efforts In Urban Agriculture: A Pathway To Indigenous Food Sovereignty And Cultural Revitalization, Sarah Fisher

Environment and Sustainability Summer Fellows

My research focuses on applications of urban agriculture, relationships between Indigenous peoples and community-based agriculture projects, and decolonizing food systems. I provide insight on colonialist tendencies, or ways in which the marginalization of Indigenous peoples is deeply entrenched within government, educational, and other leadership settings, as a way to evaluate and restructure urban agriculture projects to serve, represent and heal Native communities. Conventional urban agriculture has many known benefits, including its capacity for food production; however, the extent to which Indigenous communities participate in and benefit from urban agriculture has not been widely studied. Ongoing exclusion of Indigenous peoples from …

An Intergenerational Study Of The Entrepreneurial Nature Of Agritourism Operators, Will Culler

All Dissertations

Economic and non-economic trends have left farm operators of all ages contemplating enterprise diversification strategies to create advantages and to ensure their farms' sustainability for future generations. One such strategy is agritourism, in which a visitor to a working farm or other agricultural setting interacts with the farm landscape or participates in an agricultural process for tourism or leisure purposes. This study aims to contribute to academics, researchers, extension educators, practitioners, and farm service providers who offer training and resources to better equip current and future agritourism operators. The study tested the general hypothesis that agritourism operators' entrepreneurial goals and …

Perceptions And Management Of Ventenata By Producers In The Inland Pacific Northwest, Lisa Jones, John Wallace, Kathleen Painter, Pamela Pavek, Timothy S. Prather

Journal of Extension

Ventenata is an annual grass that has invaded agricultural and wildland settings in the Inland Pacific Northwest, causing economic and ecological losses. We know little about producers’ perceived risks and management of ventenata. We present results of surveys in 2011 and 2014 targeting producers across affected counties in Idaho and Washington. Awareness of ventenata and costs to producers increased across that time interval. Respondents attending ventenata Extension events adopted recommended management strategies more than those who did not attend. Our study documents the importance of continued integrated pest management research in concert with stakeholder engagement and education.

Expanding Effective Behavioral Health Literacy Programs To Address Farm Stress, Cheryl L. Eschbach, Courtney Cuthbertson, Gwyn Shelle, Ronald O. Bates

Journal of Extension

Attention to stress and mental health among agricultural producers has increased over recent years, and Cooperative Extension has been active in offering educational workshops and resources to agricultural audiences. This article describes the process and effectiveness of expanding two (university) Extension farm stress management programs to Cooperative Extension in other states through a national Farm Stress Management Summit. The two-day training Summit provided deeper knowledge about farm stress issues and prepared Extension professionals to offer behavioral health programs in their own communities and respective states. Evaluation findings highlight effective aspects of the Summit and next steps.

Rethinking Human-Local Wildlife Relations, Yin Chan

Critical and Creative Thinking Capstones Collection

The plight of suburban wildlife receives considerably less attention than that of exotic or endangered species despite facing similar threats due to the decline of their natural habitats as humans expand upon them. From the perspective of a reflective practitioner, this paper provides new avenues to rethink current views on human-local wildlife relations and answer some of the difficult questions surrounding the topic. The methodology of Action Research is employed to explore concepts relevant to human-local wildlife relations. A synthesized practical framework integrating Action Research with Permaculture Design is proposed to create models for mutually beneficial coexistence between local wildlife …

A Mixed Methods Approach To Context Specific Curriculum Design For Very Small And Small Strawberry Growers In The Southeastern United States, Thomas A. Yeargin

Graduate Theses and Dissertations

Outbreaks of foodborne illness due to fresh produce are a continued threat to both the publichealth and the economy in the United States. Though there are many factors which influence the perpetuation of foodborne pathogens, the inability of the food industry to curtail this issue indicates systemic failure of interventions aimed at improving food safety practices. In this dissertation, we detail the efforts made over the past few decades to provide training to food producers and food handlers as well as recommendations that have been made for improvement based on these studies. By borrowing from more advanced fields of study …

The Work Of La Via Campesina Regarding The Intersection Of Land Occupation And Food Sovereignty, Josephine Drydale

International and Global Studies Undergraduate Honors Theses

La Via Campesina (LVC), a global movement that supports small and local farmers and their communities, is one of the world’s largest food and agricultural rights movements and advocates for agricultural rights in terms of land, ecology, human rights, and more. LVC is known for its establishment of food sovereignty, defined as the right to control one’s production and consumption of food. This new concept placed them on the map, accompanied by their aggressive editorial and advocacy work against ideals they view as neoliberal and food policies that benefit large food moguls while disenfranchising the small farmer. The concept of …

The Design Of An Agricultural Youth-Centered Rural Development Program In Rwanda, Laetitia Igiraneza Sinyigenga

Honors Program: Senior Projects (Public)

Rwanda is primarily a rural, young, and agriculture-based country. The referred variables- agriculture, rural population, and youth- can be creatively merged to engage and empower youth for rural development. This paper indicates the utilization of cross-disciplinary knowledge to design an agricultural youth-centered rural development program in Rwanda. The program uses the interdependence of economic sectors (agriculture and education) with resources (environmental & natural resources and human resources) to boost rural community development. The program’s main activities- mentorship, agribusiness training, tutoring, exposure visits, and community work- highly reflect the requirement for advancing the selected main economic sectors and resources. There is …

Testing The Drosophila Maternal Haploid Gene For Functional Divergence And A Role In Hybrid Incompatibility, Dean M. Castillo, Benjamin Mccormick, Connor M. Kean, Sahana Natesan, Daniel A. Barbash

Nebraska Cooperative Extension: Faculty and Staff Publications

Crosses between Drosophila simulans females and Drosophila melanogaster males produce viable F1 sons and poorly viable F1 daughters. Unlike most hybrid incompatibilities, this hybrid incompatibility violates Haldane’s rule, the observation that incompatibilities preferentially affect the heterogametic sex. Furthermore, it has a different genetic basis than hybrid lethality in the reciprocal cross, with the causal allele in Drosophila melanogaster being a large species-specific block of complex satellite DNA on its X chromosome known as the 359-bp satellite, rather than a protein-coding locus. The causal allele(s) in Drosophila simulans are unknown but likely involve maternally expressed genes or factors since the F1 …
