Average aboveground dry biomass and height measurements were gathered for each plant bi-weekly. No significant difference was found for any of the plants in ...


Agricultural Livelihoods In Harlan County: A Case Study Approach Of Two Farms, Heather Kinney Jan 2019

Agricultural Livelihoods In Harlan County: A Case Study Approach Of Two Farms, Heather Kinney

Theses and Dissertations--Community & Leadership Development

This thesis explores agricultural livelihoods in Harlan County with two case studies in order to challenge dominant narratives about Eastern Kentucky. Harlan County, and Appalachia more broadly, is often written about in terms of its relationship to extractive industries. Absentee landownership in Appalachia has been well documented, especially in the case of coal counties. However, the relationship between extraction and agricultural livelihoods in Appalachia warrants more attention. The story of agricultural livelihoods in the region is often pushed to the periphery much like the practices of “hillside” farming. While geography makes much of the land unsuitable for farming in Harlan ...

Why Csas Matter: (Re)Localizing For People-Based Food Networks, Gretchen Alexander Jan 2019

Why Csas Matter: (Re)Localizing For People-Based Food Networks, Gretchen Alexander

Scripps Senior Theses

This thesis details the history of Claremont Market Shares, a Community Sourced Agriculture (CSA) project based out of Claremont, California. By using this project as a jumping off point for discussing local food networks, buzzwords such as "organic" and "local" are analyzed and re-defined. I argue for a people-based food network model over the currently popular 'place-based' that prioritizes producer-consumer relationships. The CSA functions as a sustainable model of this ideology.


Abundance Of Arbuscular Mycorrhizal Fungi In Organic Farmland, Conventional Farmland And Secondary Forest, Eliane S. Bach Jan 2019

Abundance Of Arbuscular Mycorrhizal Fungi In Organic Farmland, Conventional Farmland And Secondary Forest, Eliane S. Bach

Undergraduate Honors Theses

Understanding the effects of different agricultural practices on arbuscular mycorrhizal fungi (AMF) communities is important for sustainable agricultural production, since AMF play an essential role in maintaining and promoting the health of crop-plant communities. Previous studies have demonstrated that organic farming methods promote greater diversity of AMF in crops like cereal and maize, and have begun to investigate the relationship between compost and AMF in coffee crops. However, research on AMF abundance in agricultural systems in the tropics is generally lacking, especially with respect to the impact on AMF abundance of conventional farming methods – that use synthetic agrochemicals, like pesticides ...

Rna Interference Of Three Genes Of The Unfolded Protein Response: Activating Factor Of Transcription 4, Eukaryotic Translation Initiation Factor 2-Alpha Kinase, And Inositol-Requiring Enzyme 1 In Acyrthosiphon Pisum, Jared Ridder

Master's Theses

Activating Transcription Factor 4 (ATF4) is a transcription factor that can act as both an activator or repressor and is a critical component of the Unfolded Protein Response (UPR) and Amino Acid Response (AAR) pathways. Inositol-requiring enzyme 1 (IRE1) is an Endoplasmic Reticulum (ER) membrane-bound kinase/endoribonuclease that functions as a sensor of unfolded protein and is the most conserved component of the UPR in eukaryotes. Eukaryotic Initiation Factor-2-alpha Kinase (PERK) is an ER membrane bound kinase that phosphorylates eukaryotic initiation factor upon activation of the UPR causing downregulation of protein synthesis. It was hypothesized that introduction of double-stranded RNA ...

Governing Water Quality Limits In Agricultural Watersheds, Courtney Ryder Hammond Wagner Jan 2019

Governing Water Quality Limits In Agricultural Watersheds, Courtney Ryder Hammond Wagner

Graduate College Dissertations and Theses

The diffuse runoff of agricultural nutrients, also called agricultural nonpoint source pollution (NPS), is a widespread threat to freshwater resources. Despite decades of research into the processes of eutrophication and agricultural nutrient management, social, economic, and political barriers have slowed progress towards improving water quality. A critical challenge to managing agricultural NPS pollution is motivating landowners to act against their individual farm production incentives in response to distant ecological impacts. The complexity of governing the social-ecological system requires improved understanding of how policy shapes farmer behavior to improve the state of water quality. This dissertation contributes both theoretically and empirically ...

Induced Resistance In Rice, Oryza Sativa, To Herbivores In The Southern United States, Emily Clare Kraus

LSU Doctoral Dissertations

The effects of herbivory and chemical applications as potential inducers of resistance to herbivores in rice, Oryza sativa L., were explored through a series of field, greenhouse, and laboratory experiments. Studies were conducted to investigate the preference and performance of several herbivore pests of rice with a focus on, Lissorhoptrus oryzophilus Kuschel, the rice water weevil (RWW), under conditions where rice plants had been stressed by previous herbivory or chemical applications. The effects of defoliation by Spodoptera frugiperda (J.E. Smith), the fall armyworm, on resistance and tolerance of rice to RWW under field conditions were examined. Herbivory by fall ...


Rnai Targeting Of Manduca Sexta Using Chloroplast-Encoded Long Dsrna, William Burke Sep 2018

Rnai Targeting Of Manduca Sexta Using Chloroplast-Encoded Long Dsrna, William Burke

Electronic Thesis and Dissertation Repository

Pest management strategies are crucial for reducing insect crop damage, and methods with species-specific effect are particularly desirable. Expressing dsRNA with sequence complementarity to a vital gene of feeding pests is a strategy that has shown potential. I modified the chloroplast genome of cultivated tobacco, Nicotiana tabacum, by adding a sequence encoding a 2222 base pair dsRNA complementary to the vacuolar-type H+-ATPase subunit A mRNA of Manduca sexta and demonstrated expression of the product in leaves of the plants. Although feeding this same dsRNA that was synthesized in vitro to larvae knocked down expression of the target gene and ...
