Next-Generation Crispr Gene-Drive Systems Using Cas12a Nuclease, Sara Sanz Juste, Emily M Okamoto, Christina Nguyen, Xuechun Feng, Víctor López Del Amo
Journal Articles
One method for reducing the impact of vector-borne diseases is through the use of CRISPR-based gene drives, which manipulate insect populations due to their ability to rapidly propagate desired genetic traits into a target population. However, all current gene drives employ a Cas9 nuclease that is constitutively active, impeding our control over their propagation abilities and limiting the generation of alternative gene drive arrangements. Yet, other nucleases such as the temperature sensitive Cas12a have not been explored for gene drive designs in insects. to address this, we herein present a proof-of-concept gene-drive system driven by Cas12a that can be regulated …

USDA Wildlife Services: Staff Publications
Wild pigs (Sus scrofa) are one of the most successful invasive species globally and are often implicated in agricultural damage. This damage is expected to increase as ranges of wild pigs expand, impacting the human food supply and increasing costs of food production. Our objective was to evaluate movement behaviors of wild pigs relative to resource availability and landscape features in an agriculture-dominated landscape, with a goal of informing management practices for reducing damage to corn. We monitored hourly movements of adult wild pigs relative to corn crops using GPS collars during the 2019 and 2020 growing seasons (Feb–Sept) in …

Protecting Cattle Feedyard Workers In The Central States Region: Exploring State, Regional, And National Data On Fatal And Nonfatal Injuries In Agriculture And The Beef Production Sector, Athena K. Ramos, Suraj Adhikari, Risto Rautiainen, Aaron Yoder
The Journal of Extension
Working in agriculture can be dangerous. Despite ongoing efforts of Extension, animal production worker safety has not been adequately addressed. We present state, regional, and national counts and rates on fatal and nonfatal injuries in agriculture and animal production using publicly available data from the Bureau of Labor Statistics. We found that animal production had a high number of fatal injuries and a higher rate of nonfatal injuries than the average within agriculture. More needs to be done to protect livestock workers from injury. Extension professionals can play a key role in increasing safety knowledge and changing behaviors.

Accessibility And Inclusion As An Approach To Enhancing Local Extension Programs, S. Dee Jepsen, Laura Akgerman, Karen Funkenbusch, Jessie Calero, Heather Kelejian
Journal of Human Sciences and Extension
Providing accessible learning opportunities and inclusive programs are critical to Extension’s mission. Creating inclusive environments is more than consideration for individuals’ personal identity. Using principles of Inclusion, Diversity, Equity, and Accessibility (IDEA) is an approach to intentionally build community and create new opportunities for education and growth. The Americans with Disabilities Act is a federal law requiring businesses and events to be accessible to individuals with disabilities. The Rehabilitation Act of 1973 states, “no qualified individual with a disability may be discriminated against in any program or activity receiving federal financial assistance.” The legislation applies to Extension buildings, programs, and …
Rodents In Agriculture: A Broad Perspective, Gary Witmer
Rodents In Agriculture: A Broad Perspective, Gary Witmer
USDA Wildlife Services: Staff Publications
The largest taxonomic group of mammals is rodents, with over 2200 species known around the world [1]. More recently, it was stated that over 2500 species exist [2]. Many species exist on all continents, with the exception of Antarctica. Rodents have adapted to all ecosystems of the world, including tundra, alpine, temperate forests, grasslands, arid regions, and aquatic systems. They provide many ecosystem functions, including soil aeration and mixing, seed and spore dispersal, vegetation succession, and being an important food source for predatory animals. Some species of rodents are even consumed by people in some parts of the world. Most …

Towards A More Comprehensive Understanding Of Wild Pig (Sus Scrofa) Impacts On Agricultural Producers: Insights From A Texas Case Study, Keith M. Carlisle, Nicole Didero, Sophie Mckee, Julie Elser, Stephanie A. Shwiff
USDA Wildlife Services: Staff Publications
This research investigates the impacts of invasive wild pigs (Sus scrofa Linneaus) on agricultural producers in Texas, with the aim of identifying and describing all categories of wild pig impacts and quantifying the extent of producers’ over- or underestimation of their total wild pig-related costs in 2018, as compared to calculations based upon data subsequently provided by the producers about individual wild pig-related costs and losses. Based on interviews with 23 producers in 16 Texas counties, we identified more than 20 discrete categories of negative impacts and negligible positive impacts associated with wild pigs. Among them were categories that have …

Quantifying The Concentration Of 33-Mer In Wheat Flour, Abigail E. Rivas, Kaylee A. Howell, Robert Paris
Quantifying The Concentration Of 33-Mer In Wheat Flour, Abigail E. Rivas, Kaylee A. Howell, Robert Paris
Scholars Symposium
Celiac Disease is a type IV hypersensitive response to gluten caused by HLA-DQ2 or HLA-DQ8 T-cell presentation, initiating destruction of intestinal epithelial cells. Currently, the only remedy for those suffering from celiac disease is the complete elimination of all gluten from the diet. Studies indicate that an indigestible fragment of the gluten molecule, alpha-gliadin subcomponent 33-mer, rich in proline and glutamine, is responsible for the hypersensitivity response. Determination of 33-mer concentration in wheat lines could be beneficial to the future development of wheat lines with reduced 33-mer concentration. In this study, gliadin protein from wheat flour was extracted and separated …

Timing And Extent Of Crop Damage By Wild Pigs (Sus Scrofa Linnaeus) To Corn And Peanut Fields, C. M. Boyce, Kurt C. Vercauteren, James C. Beasley
Timing And Extent Of Crop Damage By Wild Pigs (Sus Scrofa Linnaeus) To Corn And Peanut Fields, C. M. Boyce, Kurt C. Vercauteren, James C. Beasley
USDA Wildlife Services: Staff Publications
The global expansion of wild pigs over the last few decades has resulted in an increase in extent and distribution of damages to crops, placing a growing strain on agricultural producers and land managers. Despite the extent of wild pig damage to agriculture, there is little data regarding timing and spatial variability of damage to corn (Zea mays Linnaeus) and we found no data regarding the effect of these factors on peanuts (Arachis hypogaea Linnaeus). Our objective was to determine the timing and extent of wild pig damage to corn and peanut fields, as well as the extent …

Movement Behavior Of Radio-Tagged European Starlings In Urban, Rural, And Exurban Landscapes, Page E. Klug, H. Jeffrey Homan
USDA Wildlife Services: Staff Publications
Since their intentional introduction into the United States in the 1800s, European starlings (Sturnus vulgaris) have become the fourth most common bird species and a nuisance bird pest in both urban and rural areas. Managers require better information about starling movement and habit-use patterns to effectively manage starling populations and the damage they cause. Thus, we revisited 6 radio-telemetry studies conducted during fall or winter between 2005 and 2010 to compare starling movements (n = 63 birds) and habitat use in 3 landscapes. Switching of roosting and foraging sites in habitat-sparse rural landscapes caused daytime (0900–1500 hours) …
Chronic Kidney Disease From Non-Traditional Causes Throughout Central America, Abigail K. Watson
Chronic Kidney Disease From Non-Traditional Causes Throughout Central America, Abigail K. Watson
Senior Theses
Throughout many Central American countries, incidence of chronic kidney disease (CKD) has been on the rise. The disease mainly affects agricultural workers and differs from typical CKD. Patients in these countries often do not have preexisting conditions such as diabetes or hypertension known to be traditional causes of CKD. They also experience increased damage to the kidney tubules, rather than the glomeruli generally more heavily impacted. There has been speculation regarding the causes of CKDnT (chronic kidney disease of nontraditional causes), but no consensus has been reached. Two major hypotheses to explain the high prevalence among Central American sugarcane workers …

Seeing Is Not Always Believing: Crop Loss And Climate Change Perceptions Among Farm Advisors, Meredith T. Niles, Sarah Wiener, Rachel E. Schattman, Gabrielle Roesch-Mcnally, Julian Reyes
College of Agriculture and Life Sciences Faculty Publications
As climate change is expected to significantly affect agricultural systems globally, agricultural farm advisors have been increasingly recognized as an important resource in helping farmers address these challenges. While there have been many studies exploring the climate change belief and risk perceptions as well as behaviors of both farmers and agricultural farm advisors, there are very few studies that have explored how these perceptions relate to actual climate impacts in agriculture. Here we couple survey data from United States Department of Agriculture farm service employees (n = 6, 514) with historical crop loss data across the United States to explore …

Sharing The Gift Of Water: A Hoosier-Haitian Partnership, Lauren Ward
Purdue Journal of Service-Learning and International Engagement
Engagement Methods for International Food Security (YDAE 49100) provided an opportunity for enrolled students to travel abroad to Cap-Haitïen, Haiti. As both a course in agriculture and a service-learning study abroad, the overarching goal was to inspire, engage, and teach Purdue and Haitian students through service learning in agriculture. This was done by developing a project with teammates during the fall semester that was then presented to students in Haiti during the International Agri-Symposium at Université Antenor Firmin over winter break.
Does Household Capital Mediate The Uptake Of Agricultural Land, Crop, And Livestock Adaptations? Evidence From The Indo-Gangetic Plains (India), Sameer H. Shah, Courtney Hammond Wagner, Udita Sanga, Hogeun Park, Lia Helena Monteiro De Lima Demange, Carolina Gueiros, Meredith T. Niles
Does Household Capital Mediate The Uptake Of Agricultural Land, Crop, And Livestock Adaptations? Evidence From The Indo-Gangetic Plains (India), Sameer H. Shah, Courtney Hammond Wagner, Udita Sanga, Hogeun Park, Lia Helena Monteiro De Lima Demange, Carolina Gueiros, Meredith T. Niles
College of Agriculture and Life Sciences Faculty Publications
Farmers in the Indo-Gangetic Plains produce much of the wheat and rice grown in India. However, food production and millions of farm-based livelihoods in this region will continue to be adversely affected by hydro-climatic change and variation, reduced land productivity, and declining groundwater levels. Thus, agricultural adaptations are essential for protecting and improving upon intersecting goals of food security, poverty alleviation, and wellbeing. Household “capital” (e.g., natural, human, financial, physical, and social) is commonly cited as an indicator of livelihood adaptability and innovation. We develop a series of mediated structural equation models to empirically evaluate the validity of capital as …

Maxwell H. Gluck Equine Research Center Faculty Publications
Recent advances in genomic sequencing technology and computational assembly methods have allowed scientists to improve reference genome assemblies in terms of contiguity and composition. EquCab2, a reference genome for the domestic horse, was released in 2007. Although of equal or better quality compared to other first-generation Sanger assemblies, it had many of the shortcomings common to them. In 2014, the equine genomics research community began a project to improve the reference sequence for the horse, building upon the solid foundation of EquCab2 and incorporating new short-read data, long-read data, and proximity ligation data. Here, we present EquCab3. The count of …

Correcting For The Inconveniences Of Cultivation: Foraging As A Food Source In Southwestern Burkina Faso, Julia Deryn Morgan
Correcting For The Inconveniences Of Cultivation: Foraging As A Food Source In Southwestern Burkina Faso, Julia Deryn Morgan
Geography Honors Projects
Malnutrition is an important public health issue in Burkina Faso where 30 % of children are underweight for their age and 92% suffer from iron deficiency. Such statistics indicate that there is a significant lack of adequate nutrition in the country. With approximately 80% of the population employed in the agricultural sector, development projects have focused on increasing agricultural production and commercializing output to ameliorate poor nutrition. However, this strategy ignores the importance of local knowledge and food traditions, most notably by neglecting to acknowledge foraging as a significant source of food. To address this concern, I seek to understand …

This issue is embracing the creation of partnerships with establishments worldwide for the provisions of life embodiments to graduates. At moment, there may be lack of friendship or partnership with establishments to create incentives for newly graduates of so many colleges and universities (Hirsh & Weber, 1999). Partnership with external companies will surely bring enormous grants to the colleges and universities and it will also encourage friendly establishments to provide incentives and perks to colleges, universities and alumni. It may be concluded that the advantages of creating rapport with external congruences is the comraderies and also compromises that will be …

Vitamin Fortification Of Milled Rice: A New Approach To Address Micronutrient Malnutrition, Drexel H. Camacho
Vitamin Fortification Of Milled Rice: A New Approach To Address Micronutrient Malnutrition, Drexel H. Camacho
Angelo King Institute for Economic and Business Studies (AKI)
To address micronutrient deficiencies in the susceptible sector of society, it is recommended to fortify the commercial milled rice with vitamins using the new technique of fortification. The simple approach, which involves rice surface modification and vitamin absorption, is deemed economical compared to traditional fortification processes. Moreover, the susceptibility of losing vitamins due to washing processes is resolved in this improved grain fortification as ~90% of the vitamins are retained. The results shown in this study indicate the successful fortification of vitamins on rice and that fortification is more pronounced when the grain undergoes sonication process. As the staple food …
