Comparison Of Comprehensive Health Score In North American Housed Giraffe And Free-Ranging Giraffe From South Africa, Haley Beer
Department of Animal Science: Dissertations, Theses, and Student Research
Stress is evident in many animal species and has been correlated to disease prevalence. During stressful events, allostasis is initiated by physiologic systems to maintain or reestablish homeostasis to protect an organism’s viability. Over time, the acclimation to frequent stress causes systematic dysregulation, leading to the phenomena of increased allostatic load. Allostatic load has been assessed in animal species via serum through selection of representative, multi-system biomarker indices. Perception and number of stress events may impact dysregulation severity, yielding allostatic load as a predictive tool. However, the allostatic load methodology poses application limitations to individuals without historical data and those …

Crop, Soil and Environmental Sciences Faculty Publications and Presentations
Confirmation of protoporphyrinogen oxidase (PPO)-resistant Palmer amaranth (Amaranthus palmeri S.Watson) in 2015 limited weed control options for soybean [Glycine max (L.) Merr.] producers. With already prevalent 5-enolpyruvyl-shikimate-3-phosphate synthase-, acetolactate synthase-, beta-tubulin-, and very-long-chain fatty acid-resistant Palmer amaranth, there are few remaining effective pre-emergence and postemergence herbicides labeled in soybean. The recent commercialization of soybean varieties resistant to dicamba and 2,4-D give producers effective options to control multiresistant Palmer amaranth. To evaluate new and existing technologies and postemergence herbicide options, two experiments were conducted in 2017. These experiments were conducted in Marion and Crawfordsville, AR, two locations with confirmed …

Crop, Soil and Environmental Sciences Faculty Publications and Presentations
On-farm water storage–tailwater recovery systems reduce groundwater usage and intercept agrochemical loads, but pesticide residue dynamics in these systems are not well understood. This study monitored concentrations of seven herbicides in seven northeast Arkansas tailwater recovery systems (April 2017–March 2018). Clomazone, glyphosate, metolachlor, and quinclorac were frequently detected, with minimal detections of 2,4-D, dicamba, and propanil. Concentrations peaked during the growing season (1 Apr.–15 Sept.), reflecting an interaction of application and precipitation. Clomazone, glyphosate, and quinclorac concentrations were greater in ditches (−1, respectively) than in the associated reservoir (−1, respectively), but metolachlor concentrations were not different between structure types (maximum …

Shifting Landscapes: The Effects Of Male Out-Migration On Food Security And Food Sovereignty In Rural Nepal, Emma Brown
Independent Study Project (ISP) Collection
Rural Nepal is experiencing rapid demographic changes, significantly impacting the socioeconomic and agricultural landscape of these areas. Growing percentages of the male population are migrating out of the country in search of better livelihood opportunities. This is largely a result of poor development processes and governmental policies that have failed to create adequate domestic livelihood opportunities and incentives to work in agriculture, as well as changing ideas on what it means to be successful, spurred by globalization. Further, dominant neoliberal ideology and the commercialization of agriculture is decreasing the profitability of agriculture, making migration a lucrative option. Due to out-migration, …

Ecological And Economic Benefits And Risks Of Using Botanical Insecticides In Tanzanian Farms, Lilia Garcia
Independent Study Project (ISP) Collection
Insect damage is a major concern for smallholder farmers in developing countries like Tanzania. Synthetic insecticides can tame infestations, however they can be expensive, inaccessible, and their misuse can threaten farmer health and ecological conditions. Botanical insecticides are cheap alternatives to treat infestations while preserving beneficial insects such as pollinators, predators, and parasitoids. This study assesses how both synthetic and botanical insecticides affect beneficial insects, crop yield and profit/costs. This study finds botanical insecticides slightly less harmful towards non-target insects. Botanical insecticides seldomly improve crop yields but usually result in a higher profit/lower cost. Due to high variation in ecological …
