Weight Status Perceptions And Food Choice, Christopher R. Gustafson
Weight Status Perceptions And Food Choice, Christopher R. Gustafson
Cornhusker Economics
Does your weight status—whether your height and weight put you into the normal weight, overweight, or obese category—predict your food choices, or even the types of food you’ll pay attention to when making a choice? What about the weight status you perceive yourself to be? These are important questions because the percentage of the population that is overweight or obese in the U.S.—and world-
wide—has been increasing for decades despite a wide range of efforts aimed at slowing/reversing its growth. In the U.S., over 70 percent of the population is overweight or obese. High body weight has numerous consequences for …

Alfanet: A Database Of Alfalfa-Bacterial Stem Blight Protein–Protein Interactions Revealing The Molecular Features Of The Disease-Causing Bacteria, Raghav Kataria, Rakesh Kaundal
Plants, Soils and Climate Student Research
Alfalfa has emerged as one of the most important forage crops, owing to its wide adaptation and high biomass production worldwide. In the last decade, the emergence of bacterial stem blight (caused by Pseudomonas syringae pv. syringae ALF3) in alfalfa has caused around 50% yield losses in the United States. Studies are being conducted to decipher the roles of the key genes and pathways regulating the disease, but due to the sparse knowledge about the infection mechanisms of Pseudomonas, the development of resistant cultivars is hampered. The database alfaNET is an attempt to assist researchers by providing comprehensive Pseudomonas proteome …
Greening The Archive: The Social Climate Of Cotton Manufacturing In The "Samuel Oldknow Papers, 1782-1924", Bernadette Myers, Melina Moe
Greening The Archive: The Social Climate Of Cotton Manufacturing In The "Samuel Oldknow Papers, 1782-1924", Bernadette Myers, Melina Moe
Journal of Contemporary Archival Studies
This article re-examines the records and correspondence of Samuel Oldknow, a late eighteenth century textile manufacturer, within the context of the environmental humanities. Oldknow’s papers, a portion of which are held at Columbia University, are most often used by economic historians to date the beginnings of the factory wage labor system. We highlight, instead, the environmental implications of Oldknow’s cotton enterprise by juxtaposing documents related to the global reach of Oldknow’s empire with evidence of his transformation of the local landscape of northern England. This process of re-scaling captures a sense of what we call the “social climate” of the …
Impacts Of Soil Management On Microbial Assemblages Involved In Nitrogen Transformations In Agroecosystems In Tennessee, Usa, Jialin Hu
Doctoral Dissertations
Nutrient reduction, particularly with respect to nitrogen (N) losses, is an important goal for sustainably managed agroecosystems. Soil N-cycling microbial populations that modulate these processes are affected by agricultural management regimes. This research focused on the controls and dynamics of the major N-cycling microbial populations in high-input cotton field under agricultural management regimes and low-input native C4 forage grass systems under pasture management practices to determine the effects of management regimes on in situ seasonal dynamics of the functional microbes responsible for N fixation, nitrification, and denitrification processes. Molecular microbial ecology methods were combined with soil physicochemical properties and …

Yield And Economic Performance Of Crop Rotation Systems In South Dakota, Hanxiao Feng, Tong Wang, Shannon L. Osborne, Sandeep Kumar
Economics Faculty Publications
Crop yield and economic profitability, both highly dependent on local crop management, soil characteristics, and weather conditions, are among the most influential factors to consider when considering a cropping system. The objective of this study was to compare the economic returns of three different 4-yr diverse crop rotations with that of a 2-yr traditional crop rotation in eastern South Dakota. The rotations included were (a) corn (Zea mays L.)–soybean [Glycine max (L.) Merr.]–spring wheat (Triticum aestivum L.)–pea (Pisum sativum L.) (CSSwP), (b) corn–pea–winter wheat–soybean (CPWwS), (c) corn–oat (Avena sativa L.)–winter wheat–soybean (COWwS), and (d) corn–soybean …
Quantifying The Combined Effect Of Abiotic Factors On The Decomposition Of Organic Matter In Semiarid Grassland Soils, Elnazsadat Hosseiniaghdam
Quantifying The Combined Effect Of Abiotic Factors On The Decomposition Of Organic Matter In Semiarid Grassland Soils, Elnazsadat Hosseiniaghdam
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Grassland ecosystems play a critical role in the global carbon cycle, and their cumulative carbon dioxide (CO2) emissions can be affected by animal grazing where litter (i.e., dead plant material) is trampled into the soil. However, the subsequent effects of trampling on litter decomposition are not well understood. Meanwhile, abiotic factors, especially temperature and soil moisture, are known to strongly affect litter decomposition. Due to the very small number of published studies that have considered litter placement, either litter on top of soil or litter mixed with soil as a factor in litter decomposition under different temperature and soil moisture …

Biology Faculty Publications and Presentations
Climate change adaptation requires building agricultural system resilience to warmer, drier climates. Increasing temporal plant diversity through crop rotation diversification increases yields of some crops under drought, but its potential to enhance crop drought resistance and the underlying mechanisms remain unclear. We conducted a drought manipulation experiment using rainout shelters embedded within a 36-year crop rotation diversity and no-till experiment in a temperate climate and measured a suite of soil and crop developmental and eco-physiological traits in the field and laboratory. We show that diversifying maize-soybean rotations with small grain cereals and cover crops mitigated maize water stress at the …

Plastic In Agricultural Soils And Its Biological Impacts, Olivia Mckay
Plastic In Agricultural Soils And Its Biological Impacts, Olivia Mckay
Master of Science in Environmental Sciences and Management Projects
Agricultural plastic mulch reduces weeds, yields higher crop quality and quantity, and increases soil temperature, but it can also become a soil pollutant. The impact of agricultural plastic contamination on soil microbial activity remains poorly documented. To better understand how plastic pollution influences soil microbial decomposers, we sampled three farms in Watsonville, CA. Each site is characterized by large amounts of plastic contamination in the form of polyethylene mulch and polyvinyl chloride dripline. The fields contain marked amounts of macro- (and presumably micro-) plastic fragments primarily derived from PVC dripline and polyethylene mulch. We haphazardly collected 6" deep soil samples …
Impacts Of Crop Insurance And Intra-Season Hedging On Long-Run Net Income Risk, Kara Zimmerman
Impacts Of Crop Insurance And Intra-Season Hedging On Long-Run Net Income Risk, Kara Zimmerman
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Each year producers must make risk management decisions early in the growing season when many variables are unknown. In this thesis we create an empirical model utilizing thirty years (1989-2018) of historical yield, cost, and daily price series data, to determine the optimal risk management strategy of crop insurance and an intra-season marketing plan that will both minimize net income risk and maximize average net income. The empirical model is taken a step further to include an out-of-sample year in order to test the robustness of empirical results to financially devastating events that have never been seen. We test the …
Development Of High Value Oil Traits Using The Model Oilseed Crop Camelina Sativa, Evan Updike
Development Of High Value Oil Traits Using The Model Oilseed Crop Camelina Sativa, Evan Updike
Department of Biochemistry: Dissertations, Theses, and Student Research
Plant oils are an important source of food, fuel, and feed in our society today. The oil found in the seeds of plants is composed almost entirely of triacylglycerol (TAG) molecules, which consist of three fatty acids esterified to a glycerol backbone. As crude oil supplies decline, vegetable oils are gaining traction as a renewable substitute to petroleum-based materials in fuels, lubricants, and specialty oleochemicals. However, as it currently stands vegetable oils do not possess the properties necessary to fill the void of a petroleum free world.
To address this problem, plant biotechnologists have done extensive work on genetic engineering …
Identification Of Qtls For Berry Acids And Sugar In A Vitis Aestivalis-Derived 'Norton'-Based Population, Karlene Louise Negus
Identification Of Qtls For Berry Acids And Sugar In A Vitis Aestivalis-Derived 'Norton'-Based Population, Karlene Louise Negus
MSU Graduate Theses
Acidity and sugar content are among the grape berry quality traits that influence wine quality. Despite advantageous environmental tolerances of Vitis aestivalis-derived ‘Norton’, its acid and sugar concentrations often deviate from expectations set for V. vinifera. Identification of the genetic determinants of malic acid, tartaric acid, pH, and total soluble solids (TSS) can assist in the improvement of new hybrid cultivars. For this purpose, a ‘Norton’ and V. vinifera ‘Cabernet Sauvignon’ hybrid mapping population containing 223 individuals was used to construct a linkage map containing 384 simple sequence repeat (SSR) and 2084 genotyping-by-sequencing (GBS)-derived single nucleotide polymorphism (SNP) …

Therefore; the objective of this study was to understand the complex causal and feedback relationships for this system by developing a dynamic hypothesis and causal loop diagrams utilizing the System Dynamics methodology. Results provide a roadmap for dialogue and a framework for case-specific model development and help to guide policy decisions for smallholder farmers’ survival during health crises.
Risk Management Potential Of Supplemental Irrigation For Cotton In A Sub-Humid Climate Under Climate Change, Wen Liu
Masters Theses
Adoption of supplemental irrigation to reduce cotton yield losses is a potential risk management strategy for farmers given increasingly frequent drought periods due to climate change. However, cotton farmers in the rolling landscape areas of the lower Mississippi River Basin (MRB) are concerned about whether an investment in supplemental irrigation is economically feasible. This study determined the impacts of the effects of risk exposure on optimal irrigation strategies for cotton production under climate change in West Tennessee. A crop simulation model was calibrated and validated using measured data from cotton irrigation experiments at Jackson, TN over three years (2006–2008). Simulated …

Marker-Assisted Selection To Determine The Introgression Of Rpv-3 Mediated Downy Mildew Resistance In 'Chambourcin' X 'Caberenet Sauvignon' Grapevine Population, Kavya Sri Tummala
MSU Graduate Theses
Downy mildew caused by the fungus, Plasmopara viticola in the grapes is one of the major diseases affecting crop yield throughout the world. Breeding grapes via conventional methods for the downy mildew resistance will take approximately 25-30 years to fully evaluate and release new cultivars. Because of the long breeding cycle in woody plant species like grape, developing DNA markers linked to genes or quantitative trait loci (QTLs) for horticultural traits can greatly accelerate the breeding process and allow a much more accurate selection of progeny. This study aims to determine the presence of resistance in the 267 F1 genotypes …

No differences were observed in initial BW, final BW, BW gain, HCW, LM area, 12th rib fat depth, calculated YG, or liver abscess %. Dry matter intake linearly increased as Green Grass inclusion increased in the diet. Steers fed Green Grass had lower G:F than control cattle, and steers fed 30% Green Grass had a …
Estimation Of Breed Effects And Genetic Parameters For Age At Slaughter And Days To Finish In A Multibreed Beef Cattle Population, Lindsay Upperman
Estimation Of Breed Effects And Genetic Parameters For Age At Slaughter And Days To Finish In A Multibreed Beef Cattle Population, Lindsay Upperman
Department of Animal Science: Dissertations, Theses, and Student Research
Cattle efficiency during the finishing phase is a crucial factor in determining profit in the beef cattle industry. Economically relevant traits associated with efficient production include age at slaughter (AAS) and days to finish (DtF). Selection to reduce the number of days an animal takes to reach a finish endpoint would ultimately reduce production costs, increase net profits, and result in a more sustainable production system. However, most harvested animals are from commercial herds, necessitating the use of indicator traits from seedstock animals for selection. Potential indicator traits include ultrasound measurements that could be genetically correlated to DtF traits. The …

Variation In Trichome Types And Density Mediates Plant-Herbivore Interactions In Two Cucurbitaceae Members, Ishveen Kaur
Theses and Dissertations
Plant structural defenses such as trichomes and spines exert a significant selection pressure on insect herbivores. However, how species variation affects structural defense trait expression in closely related species is less understood. Through our studies, we tried to dissect the role of trichomes in mediating plant-insect interactions, in two non-model cultivated species in Cucurbitaceae: Lageneria siceraria, and Cucumis sativa family, and Trichoplusia ni as our major herbivore of interest. We observed that species differed in their attractiveness to different herbivores and their feeding behavior in common garden experiment. To tease apart structural and chemical defenses and their independent roles …
Intercropping And Denisity Impacts In A Lettuce And Chard Agroecosystem, Sophia Moser
Intercropping And Denisity Impacts In A Lettuce And Chard Agroecosystem, Sophia Moser
Master of Science in Environmental Sciences and Management Projects
Conventional agriculture that uses machinery management, synthetic fertilizers, and pesticides, is a contributor to greenhouse gas emissions, reduction of biodiversity and soil health. Agroecological methods, such as intercropping, have the potential to make farming more sustainable, financially feasible and to be implemented on a large scale. Gaps in agricultural research have led to limited information as to how intercropped arrangements can be adapted to be as productive as conventional systems. This research evaluates the ecological and economic performance of a lettuce and chard agroecosystem, specifically investigating the impact that density and intercropping has on plant productivity and profitability. Both species …

This study will analyze small-scale poultry farming in the Musanze district of Rwanda. Poultry farming offers a source of protein and economic subsistence for households in this region but studies suggest that the smallholder farmers need training for effective production of broiler for these purposes. To this end, a project - Feed the Future Tworore Inkoko, Twunguke (TI) - funded by the United States Agency for International Development (USAID) and the African Sustainable Agriculture Project (ASAP) Foundation, and led by the University of Tennessee Institute of Agriculture (UTIA) and Zamura Feeds Ltd., was initiated to help the smallholder broiler farmers …
Supplementing East Tennessee Landscapes For Pollinators With Native Perennials, Amani Khalil
Supplementing East Tennessee Landscapes For Pollinators With Native Perennials, Amani Khalil
Masters Theses
Tennessee, home to the Great Smoky Mountains, is a biodiversity hotspot for many plant and animal species, yet it receives relatively few conservation dollars (Jenkins et al., 2015). As a biodiversity hotspot, this region may be home to many endemic species, but little is known about the abundance or diversity of insect pollinators. In order to both estimate pollinator communities in East Tennessee and pollinator forage preferences for native Tennessee plants, we established four plots, comprised of three plant families across five common land use types. Over two field seasons we collected nearly 7,300 insect specimens with a total sampling …
