Root Phenotyping Of Peptide-Treated Glycine Max, Salem Jackson

Biological Sciences Undergraduate Honors Theses

Plant elicitor peptides (Peps) – endogenous chains of amino acids involved in natural plant defense – have been shown to decrease damage from herbivores and pathogens by inducing an immune response, increasing the emission of volatile organic compounds (VOCS), transcripts, and metabolites. Exogenous treatment of soybean seeds with plant elicitor peptide GmPep3 has been shown to induce these broad-spectrum defenses and offers a new method for increasing crop yield. However, the effects of GmPep3 on indicators of soybean health – root characteristics, growth stages, etc. – have not been fully realized.

Using the root-phenotyping platform RhizoVision Explorer, several root traits …

We found that gender significantly affects how one uses natural resources in Madagascar. Men were primarily responsible for the …

Arsenic : Risk, Exposure, Policy And Management, Nadia Binte Jamil

Theses, Dissertations and Culminating Projects

Arsenic (As) contamination in drinking water is a global concern. About 150 million people from 70 countries in the world are at risk to health hazards associated with As contamination. In this study, we compared four As mitigation approaches practiced in Bangladesh and their costs. Our results show that intervention that is associated with the lowest cost of exposure reduction is testing and switching ($3/person), followed by intermediate wells ($28/person), deep tube wells ($143/person), and piped water supply system ($158/person). We then prioritized affected villages to reduce exposure and facilitate mitigation using three criteria: weighted exposure (mean As concentration x …

How Can Stakeholders In Food Sovereignty Achieve More Political Power?, Micah Dierks

Department of Environmental Studies: Undergraduate Student Theses

Food sovereignty (FSv) is a peasant-driven, transnational movement that emerged in response to land-grabbing and the consolidation of power in food production. It advocates for the rights of people to define their own food practices and systems. To provide targeted feedback for movement reflexivity, 21 ecological conflicts referencing food sovereignty were sampled from the Global Atlas of Environmental Justice (the EJAtlas). Involved groups of actors and their forms of mobilization were correlated with interpretations of success from the EJAtlas. I recommend that stakeholders in food sovereignty pursue the acquisition of greater political power through improving messaging, leveraging or disrupting existing …

Reintroduction Of The Grey Wolf, Cody Willers

Department of Environmental Studies: Undergraduate Student Theses

A comprehensive literature review of the topic of the reintroduction of the grey wolf (Canis lupus) into the lower 48 states has been conducted to determine the viability of the grey wolf as a method for managing the overgrowth of medium to large ungulate populations. Due to the overgrowth of medium to large ungulate populations without the presence of the grey wolf, detrimental environmental impacts were being seen on many ecosystems such as Yellowstone in North America. Through predation and the fear of predation, the presence of the grey wolf in these ecosystems can provide a solution to the negative …

Effects Of Invasive Wild Pigs And Supplemental Feeding On Wildlife In The Piedmont Region Of South Carolina, Elizabeth A. Saldo

All Theses

Wild pigs (Sus scrofa), which are invasive in much of the world, can alter ecosystems and compete with native species through interference competition and resource exploitation. We assessed the potential for interspecific interactions between invasive wild pigs and other wildlife in the Piedmont region of South Carolina by examining their spatiotemporal overlap in a correlational field study and an experimental field study. Our correlational study used data from wildlife cameras in seasonal occupancy, N-mixture, and temporal overlap analyses.

Effects Of Forest Management On Early-Successional Avian Species In The Southern Blue Ridge Ecoregion, Michael J. Adams

All Theses

Early-successional habitats are a critical habitat type for Ruffed Grouse (Bonasa umbellus) and Golden-winged Warblers (Vermivora chrysoptera). In the Southern Blue Ridge Ecoregion, early-successional habitats have declined over the last 70 years, and the extent of which Ruffed Grouse and Golden-winged Warblers occupy these habitats at the edge of their ranges is unknown. Understanding the factors that drive the presence or absence of these species in this region is critical to inform quality management of early-successional forests. Additionally, increased knowledge of these species will likely benefit other species of conservation concern that rely on early-successional forests, …

Introduction Of Human Acidic Fibroblast Growth Factor (Fgf1) Variant With Increased Stability And Bioactivity, Azadeh Tavousi Tabatabaei

Graduate Theses and Dissertations

Human acidic Fibroblast Growth Factor 1 (FGF-1) involves in a broad spectrum of biological processes, including cell growth, proliferation, differentiation, migration, angiogenesis, wound healing, and embryonic development. hFGF1 non-selectively binds to cell surface hFGF receptor isoforms to elicit these cell-signaling processes. Since hFGF1 plays a significant role in tissue repair activity, that is a prime candidate for novel wound healing therapeutics. However, hFGF1 has been found to unfold near physiological temperature due to a strong electrostatic repulsion created by a dense cluster of positively charged amino acids near the c-terminus. The problem not only leads to proteolytic degradation of the …

Multi Elemental Analysis Of Cannabis Oil Based Products Using Icpms And Microwave Assisted Digestion., Kevin Trevon Marchbanks-Owens

Theses (2016-Present)

Due to the presence of CBD-(cannabidiol), bioavailable elements as well as industry versatility and relatively low levels of toxicity to the environment. CBD oils have driven the overall demand for Cannabis based plant products in the commercial and medical sector. However, dependent upon the environmental circumstances upon which these plants are grown can leave them susceptible to toxic heavy metal exposure. In fact, the natural metabolism of Cannabis plants makes them a hyperaccumulator of trace metals. This creates a severe health risk for CBD product consumers especially for more vulnerable populations with pre-existing conditions. Furthermore, the risk of heavy metal …

Potato Processing In The Home: Sustainability And Nutritional Impacts, Aubin Payne

Biological and Agricultural Engineering Undergraduate Honors Theses

Potatoes are the world's fourth most consumed crop. Their versatility and long shelf-life make them a staple food for millions of people worldwide. Still, the increasing consumption of highly processed potato products in developed countries has damaged the public's appreciation of potatoes as a valuable source of essential nutrients. Additionally, as public awareness of environmental sustainability increases, the average consumer is more likely to value processing methods that mitigate environmental damage.

Researchers simulated several home storage and processing conditions to find out how nutrition and environmental impact are affected by the home processing timeline. Then, a nutrient analysis, life cycle …

Sensory Comparison Of Beer Carbonated Using Forced Carbonation And The Carbo Rock-It, Michala Smith

Biological and Agricultural Engineering Undergraduate Honors Theses

Craft brewing is a growing market which represents over 12% of beer produced in the United States. Dr. G Scott Osborn, PE invented the Carbo Rock-It™ to improve the carbonation process for craft breweries. The invention allows for shorter carbonation time and uses less CO₂, saving companies money and time. Because of the lack of gas losses through bubbling, Osborn theorized that the Carbo Rock-It could also prevent the “stripping of the nose” that can occur in traditional forced carbonation. Existing research supports the mechanism, as beer flavor and aroma volatiles have been detected during the release of …

Implications Of Metal Coordination In Damage And Recognition Of Nucleic Acids And Lipid Bilayers, Ana Dreab

Chemistry & Biochemistry Theses & Dissertations

Metal ions have a myriad of biological functions from structural stability to enzymatic (de)activation and metabolic electron transfer. Redox-active metals also mediate the formation of reactive oxygen species which may either cause oxidative damage or protect cellular components. Computational modeling is used here to investigate the role of (1) metal-ion binding to antimicrobial peptides, (2) metal-ion removal and disulfide formation on zinc finger (ZF) proteins, and (3) coordination of thiones/selones for the prevention of metal-mediated redox damage.

Piscidins, natural-occurring antimicrobial peptides, efficiently kill bacteria by targeting their membranes. Their efficacy is enhanced in vitro by metal-binding and the presence of …

Combining Pharmacokinetics And Vibrational Spectroscopy: Mcr-Als Hard-And-Soft Modelling Of Drug Uptake In Vitro Using Tailored Kinetic Constraints, David Perez-Guaita, Guillermo Quintas, Zeineb Farhane, Roma Tauler, Hugh Byrne

Articles

Raman microspectroscopy is a label-free technique which is very suited for the investigation of pharmacokinetics of cellular uptake, mechanisms of interaction, and efficacies of drugs in vitro. However, the complexity of the spectra makes the identification of spectral patterns associated with the drug and subsequent cellular responses difficult. Indeed, multivariate methods that relate spectral features to the inoculation time do not normally take into account the kinetics involved, and important theoretical information which could assist in the elucidation of the relevant spectral signatures is excluded. Here, we propose the integration of kinetic equations in the modelling of drug uptake and …

Red Harvester Ant (Pogonomyrmex Barbatus F. Smith; Hymenoptera: Formicidae) Preference For Cover Crop Seeds In South Texas, Lilly Victoria Elliott-Vidaurri, Daniella Rivera, Adrian Noval, Robin A. Choudhury, Hannah J. Penn

School of Earth, Environmental, & Marine Sciences Faculty Publications

Harvester ants often selectively forage seeds, causing these ants to be viewed as pests in agricultural areas where they may forage on crop seeds. While little research has been done on harvester ant preferences for cover crop seeds, grower observations in the Lower Rio Grande Valley (LRGV) suggest that ants may remove these seeds before germination. We examined red harvester ant (Pogonomyrmex barbatus F. Smith) preferences for cover crop seeds (fescue, oat, sunn hemp, radish, vetch, and wheatgrass) and the effects of a commonly used bacterial seed inoculant. We evaluated relative preferences using seed depots presented to colonies with no …
