Invasive Phragmites Australis Management In Great Salt Lake Wetlands: Context Dependency And Scale Effects On Vegetation And Seed Banks, Christine B. Rohal 2018 Utah State University

Invasive Phragmites Australis Management In Great Salt Lake Wetlands: Context Dependency And Scale Effects On Vegetation And Seed Banks, Christine B. Rohal

All Graduate Theses and Dissertations

Invasive plants can outcompete native plants, replacing diverse plant communities with monocultures, which can negatively impact the whole ecosystem. One invasive plant, Phragmites australis, has invaded wetlands across North America. In Utah’s Great Salt Lake, it has greatly reduced the area of native plants that are important habitat for migratory birds. Here we describe experiments that assess multiple treatments for Phragmites removal and evaluate the return of native plants after Phragmites management. The treatments were applied to Phragmites patches at two scales (small 1/4-acre plots and large 3-acre plots) and across multiple sites to evaluate how patch size ...


Pharmacologically Induced Meiosis Apomeiosis Interconversions In Boechera, Arabidopsis And Vigna, Lei Gao 2018 Utah State University

Pharmacologically Induced Meiosis Apomeiosis Interconversions In Boechera, Arabidopsis And Vigna, Lei Gao

All Graduate Theses and Dissertations

Apomixis is a clonal propagation method that produces offspring identical to the mother plant. With this feature, superior traits could be maintained over generations. However, our knowledge about apomixis is limited. In this study, we analyzed several apomictic Boechera embryologically to learn the details of apomixis. Meanwhile, we designed chemical treatments to successfully induce sex in apomictic plants and apomixis in sexual plants. Our experiments suggest that sex and apomixis coexist in plants and that sexual and apomictic reproduction are switchable by treating with specific chemicals.

Land Cover And Use Change In Utah: A Comparison Of Field- Vs. Aerial Image-Based Observations, Jennifer Lynn Bakken

All Graduate Theses and Dissertations

The Image-based Change Estimation program (ICE) was developed by the US Forest Service Forest Inventory & Analysis (FIA) program and the Geospatial Technology Applications Center in response to the 2014 Farm Bill calling for more timely and accurate estimates of land cover and use change. ICE monitors change throughout the US on a state by state basis by assessing each FIA plot using high resolution imagery from two dates in time. In the western US, FIA measures 10% of the plots each year to report on status, trends, and sustainability of our Nation’s forests. However, this 10 year cycle misses ...


The Rational Design, Synthesis, Characterization, And Biological Evaluation Of Cancer-Targeting Immunostimulatory Peptide-Protein Conjugates And Tripeptides, Keith Smith 2018 Seton Hall University

The Rational Design, Synthesis, Characterization, And Biological Evaluation Of Cancer-Targeting Immunostimulatory Peptide-Protein Conjugates And Tripeptides, Keith Smith

Seton Hall University Dissertations and Theses (ETDs)

With the advent of cancer immunotherapy and the rise in applications of synthetic biologics, there has been a steady decline in the incidence of cancer. Despite this trend, there is an anticipated 1.7 million new cancer cases with an estimated 610,000 deaths expected by the end of 2018.2 Therefore, the call for continued efforts in creating more effective treatment options are still in high demand. In this thesis, the rational design of a semi-synthetic cancer-targeting immunostimulatory peptide-protein bioconjugate—using N-succinimidyl carbamate chemistry is described. This bio-orthogonal chemistry approach was used to conjugate the synthetic Pep42, cancer-targeting peptide ...


Divergent Rnai Biology In Mites And Development Of Pest Control Strategies, Md Mosharrof Hossain Mondal 2018 The University of Southern Mississippi

Divergent Rnai Biology In Mites And Development Of Pest Control Strategies, Md Mosharrof Hossain Mondal

Dissertations

RNA interference (RNAi) has transformed genetics research by revolutionizing reverse genetics in the nearly three decades that have passed since its discovery. ~19-31 nt small non-coding RNAs play a central role in RNAi biology, and are found in all multicellular eukaryotes. In these animals, three major classes of small RNAs have been described: microRNA (miRNA), small interfering RNA (siRNA), and Piwi interacting RNA (piRNA), which are produced in distinct yet occasionally overlapping pathways. While miRNAs are involved in tuning endogenous gene expression, piRNAs and siRNAs are essential for defense against viruses and transposons. Argonaute proteins are the main effectors in ...


Impact Of Shade On Performance And Heat Stress Of Finishing Cattle And Pooled Analysis Of Individually Fed Finishing Trials, Brett A. Melton 2018 University of Nebraska-Lincoln

Impact Of Shade On Performance And Heat Stress Of Finishing Cattle And Pooled Analysis Of Individually Fed Finishing Trials, Brett A. Melton

Theses and Dissertations in Animal Science

A commercial feedyard trial in Eastern Nebraska evaluated the effect of shade vs no shade on cattle performance, ear temperature, and panting scores. No differences in overall performance (final BW, DMI, ADG, and G:F) or carcass characteristics (HCW, 12th rib fat thickness, marbling, LM area, and calculated YG) were observed. Cattle that were provided shade had lower panting scores and ear temperatures, and greater DMI, compared to cattle that had no shade during heat events. Also, a treatment by hour interaction for movement of cattle occurred for one of the heat events. In comparison, the cool event had ...


Spray Characterization And Herbicide Efficacy As Influenced By Pulse-Width Modulation Sprayers, Thomas R. Butts 2018 University of Nebraska-Lincoln

Spray Characterization And Herbicide Efficacy As Influenced By Pulse-Width Modulation Sprayers, Thomas R. Butts

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Pesticide applications are a heavily scrutinized facet of today’s agricultural industry, and a concerted effort to optimize each application needs to be implemented. More precise and efficient pesticide applications are necessary to meet regulatory demands and increase economic efficiency through reduced pesticide inputs. Current pesticide application methods using precision technologies, including pulse-width modulation (PWM) sprayers, can assist with these goals. However, vast advancements in pesticide formulations, adjuvants, and nozzles, as well as the increasing popularity of PWM systems, have only increased the need for applied PWM and weed science research. Additionally, efforts have been placed on increasing spray droplet ...

Examining The Associative Learning And Accumbal Dopaminergic Mechanisms Of Caffeine Reinforcement, Curtis Bradley 2018 East Tennessee State University

Examining The Associative Learning And Accumbal Dopaminergic Mechanisms Of Caffeine Reinforcement, Curtis Bradley

Electronic Theses and Dissertations

Caffeine is the most consumed psychoactive substance in the world, and most caffeine consumption in coffee and energy drinks is intended to produce a psychoactive effect. However, caffeine is not a primary reinforcer in preclinical paradigms – non-human species do not reliably take the drug to produce a psychoactive effect. However, caffeine is a ‘reinforcement enhancer’ in preclinical models; the effects of caffeine increase the motivation to obtain other non-drug reinforcers. The overall goal of this project was to determine if these reinforcement enhancing effects of caffeine could promote caffeine self-administration and to subsequently investigate the behavioral and neurochemical underpinnings of ...


Haemosporidian Parasite Community In Migrating Bobolinks On The Galapagos Islands, Noah G. Perlut, Patricia G. Parker, Rosalind B. Renfrew, Maricruz Jaramillo 2018 University of New England

Haemosporidian Parasite Community In Migrating Bobolinks On The Galapagos Islands, Noah G. Perlut, Patricia G. Parker, Rosalind B. Renfrew, Maricruz Jaramillo

Environmental Studies Faculty Publications

Bobolinks (Dolichonyx oryzivorus) migrate from their breeding grounds in North America to their wintering grounds in South America during the fall each year. A small number of Bobolinks stop temporarily in Galapagos, and potentially carry parasites. On the North American breeding grounds, Bobolinks carry a least two of the four Plasmodium lineages recently detected in resident Galapagos birds. We hypothesized that Bobolinks carried these parasites to Galapagos, where they were bitten by mosquitoes that then transmitted the parasites to resident birds. The haemosporidian parasite community in 44% of the Bobolinks we captured was consistent with those on their breeding grounds ...


Implementation Of Iso/Iec Practices In Small And Academic Laboratories, Eric Layne Oliver 2018 University of Nebraska-Lincoln

Implementation Of Iso/Iec Practices In Small And Academic Laboratories, Eric Layne Oliver

Dissertations, Theses, & Student Research in Food Science and Technology

Food Manufacturers are facing challenging times due to regulations such as the Food Safety Modernization Act (FSMA) requiring them to provide evidence they are producing safe foods. Food testing laboratories aid in the mitigation of food safety issues providing evidence that a manufacturers food safety system is acceptable. To perform these activities laboratories are required to adhere to certain standards such as ISO/IEC 17025 General Requirements for the Competence of Testing and Calibration Laboratories. However, implementation of ISO/IEC 17025 practices is challenging, especially for small and academic laboratories, due to lack of available guidance. A long-term goal of ...


Effects Of Livestock Grazing Management Practices On Greater Sage-Grouse Nest And Female Survival, Seth J. Dettenmaier 2018 Utah State University

Effects Of Livestock Grazing Management Practices On Greater Sage-Grouse Nest And Female Survival, Seth J. Dettenmaier

All Graduate Theses and Dissertations

The decline in greater sage-grouse (Centrocercus urophasianus; sage-grouse) populations across western North America has been primarily attributed to loss and fragmentation of their sagebrush (Artemisia spp.) habitats. This habitat loss is largely the result of increased human activities, with grazing by domestic livestock as the most predominant land use across the sagebrush ecosystem in North America. The goal of my research was to increase our understanding of the effects of livestock on sage-grouse populations. I reviewed the peer-reviewed literature for all published studies that reported potential effects of grazing on grouse species worldwide. I found that there was an overall ...


The Effect Of Physical Application Parameters On Herbicide Efficacy And Droplet Size., Andre de Oliveira Rodrigues 2018 University of Nebraska-Lincoln

The Effect Of Physical Application Parameters On Herbicide Efficacy And Droplet Size., Andre De Oliveira Rodrigues

Theses, Dissertations, and Student Research in Agronomy and Horticulture

One of the largest challenges in agriculture is weed management. Improper or sub-optimal application techniques can cause decreased weed control and increased environmental contamination. Effective weed management is highly correlated with the product and the application method. Herbicide performance are affected by environmental conditions; they influence the physiology and growth of a plant and as well the herbicide performance. Among all environmental factors, rain shortly after herbicide application is one of the most harmful issues to the performance of the herbicide. Droplet size is a key factor in pesticide applications in regards to both drift and efficacy. Droplet size can ...


Hiv Integrase Inhibitor Pharmacogenetics And Clinical Outcomes: An Exploratory Association Study, Derek E. Murrell 2018 East Tennessee State University

Hiv Integrase Inhibitor Pharmacogenetics And Clinical Outcomes: An Exploratory Association Study, Derek E. Murrell

Electronic Theses and Dissertations

As HIV is now primarily a chronic condition, treatment is given life-long with changes as necessitated by alterations in tolerability and efficacy. Thus, personalized medicine may be useful in the prevention of unnecessary drug exposure and avoidable side effects. Three of the four currently available HIV integrase strand transfer inhibitors (INSTIs), raltegravir, elvitegravir, and dolutegravir, are widely utilized antiretrovirals in the USA and exhibit variations in outcomes among subjects. To interrogate differences among subjects receiving these drugs, we investigated the association of several single nucleotide polymorphisms (SNPs) with drug exposure, clinical outcomes, and subject-reported adverse events. HIV+ adults (≥18 years ...


Identification And Characterization Of Salinity Tolerance Genes By Activation Tagging In Arabidopsis, Jawaher Alkahtani 2018 University of Arkansas, Fayetteville

Identification And Characterization Of Salinity Tolerance Genes By Activation Tagging In Arabidopsis, Jawaher Alkahtani

Theses and Dissertations

Salinity often affects irrigated areas in arid and semi-arid regions of the world. The existence and accumulation of soluble salts in the soil layers limit the growth of crops essential for our food. Salt stress dramatically affects plant growth, plant development, as well as crop yield. Arabidopsis thaliana is the plant model that provides a comprehensive knowledge of plant development, genetics and physiology, and response to abiotic stresses such as salinity. The redundancy of genes due to duplication, even in the simple model genome of Arabidopsis, limits the value of knockout (KO) mutagenesis to provide complete information on gene function ...

Metabolic Plasticity In The Cellular Stress Response, Ying Li 2018 East Tennessee State University

Metabolic Plasticity In The Cellular Stress Response, Ying Li

Electronic Theses and Dissertations

Changes to the metabolism of the cardiomyocyte are driven by complex signaling pathways in order to adjust to stress. For instance, HIF-1α is classically known to upregulate glycolytic metabolism to compensate for oxygen deficiency. Other important effects upon glucose metabolism, which we investigate here more extensively, were also observed. Hearts derived from mice with the cardiac-restricted expression of a stabilized form of HIF-1α are remarkably ischemia stress-tolerant. Here, stable isotope-resolved metabolomic analyses were utilized to investigate glucose cardiometabolism remodeling by HIF-1αduring ischemia. We found that 13C-lactate accumulation was significantly elevated in HIF-1α expressing hearts while paradoxically glycogen was maintained ...


14-3-3 Protein Rad24 And Its Effect On Mid1 Localization And Contractile Acto- Myosin Ring Assembly During Cytokinesis In S. Pombe, Anissa P. Grawe 2018 Grand Valley State University

14-3-3 Protein Rad24 And Its Effect On Mid1 Localization And Contractile Acto- Myosin Ring Assembly During Cytokinesis In S. Pombe, Anissa P. Grawe

Masters Theses

In animal and yeast cells, cell division (cytokinesis) is facilitated by the formation of a contractile acto-myosin ring (CAR). Proper CAR formation and constriction is heavily reliant on the temporal regulation, phosphorylation, and localization of key proteins. In the fission yeast S. pombe, Mid1 is an important dimeric CAR scaffolding protein that connects the contractile apparatus to the plasma membrane at the right place and time during cytokinesis. Mid1 is confined to both the nucleus and protein assemblies called nodes during interphase, and transitions to the cell cortex at mitotic entry as nodes mature and coalesce into the CAR. Rad24 ...
