Exploring Alternative Giant Salvinia (Salvinia Molesta D.S. Mitchell) Management Strategies, Bradley T. Sartain

LSU Doctoral Dissertations

Dense infestations of the free-floating aquatic fern giant salvinia (Salvinia molesta D.S. Mitchell) have been expanding across the southeastern United States for over two decades. Although herbicide programs have provided relief to giant salvinia infested areas, morphology and growth characteristics make management difficult. A series of mesocosm trials were conducted to explore alternative management strategies for giant salvinia. Evaluation of non-registered aquatic herbicides showed that rates of sulfometuron and metsulfuron controlled giant salvinia and provided a 98 to 100% biomass reduction. An outdoor mesocosm trial evaluated potential glyphosate resistance in giant salvinia in select water bodies throughout Louisiana. Differences …

Development, Acceptability, And Emotional Responses Of Low-Sodium Roasted Peanuts And Flavored Spreads, Kairy Dharali Pujols Martinez

LSU Doctoral Dissertations

The objective of this research was to evaluate the feasibility of developing acceptable low-sodium products by using a salt-replacement technique, an oil-in-water emulsion system, and health benefit information to improve consumers’ awareness of low-sodium diets. Three experiments were conducted: (I) Sensory characteristics and optimization of low-sodium roasted peanuts by substitution of NaCl with KCl, and addition of glycine (Gly) as a bitterness blocker; (II) Rejection threshold (RjT) of KCl added to low-sodium roasted peanuts using a 2AC-test; (III) Development of acceptable low-sodium and sodium-free spreads by flavor modification and their use on turkey salad sandwiches. In study I, results showed …

Role Of Mucin 19 In The Respiratory Tract, Kaitlin Mcbride

LSU Master's Theses

Human metapneumovirus (HMPV) is a negative sense, single stranded RNA virus belonging to the Pneumoviridae family, and represents an important pathogen that causes severe respiratory disease worldwide. There is currently no vaccine against HMPV, so it is important to study the aspects of the immune response induced by HMPV. Because infiltration of mucus is a hallmark of HMPV infection, it is warranted to study the role of mucus in the disease process. Mucin proteins make up the major component of mucus and can be found within the airway and lungs. Previous work from our laboratory demonstrated a high upregulation of …

R1 Retrotransposons In Drosophila Melanogaster Are Transcribed By Rna Polymerase I Upon Heat Shock, Himanshu Shekhar Raje

LSU Doctoral Dissertations

The ribosomal RNA genes of Drosophila melanogaster reside within centromere-proximal nucleolar organizers on both the X and Y chromosomes. Each locus contains between 200-300 tandem repeat rDNA units that encode 18S, 5.8S, and 28S ribosomal RNAs (rRNAs) for ribosome biogenesis. In arthropods like Drosophila, about 60% of rDNA genes are inserted with R1 and/or R2 retrotransposons at specific sites within the 28S regions; these units likely fail to produce functional 28S rRNA. We showed previously that R2 expression increases upon nucleolar stress caused by the loss of a ribosome assembly factor, the Nucleolar Phosphoprotein of 140 kDa (Nopp140). Here …

Influence Of Black Mangrove Expansion On Salt Marsh Faunal Communities Of Eastern Coastal Louisiana, Christina Powell

LSU Master's Theses

The salt marshes along the Gulf of Mexico provide a critical habitat for many species, but their spatial distribution is changing, because Avicennia germinans (black mangroves) are expanding due to warmer winters. Currently, little is known about how A. germinans are used as habitat providing food and refuge for aquatic fauna. Therefore, the overall goal of this study was to determine how A.germinans expansion into the Spartina alterniflora (smooth cordgrass) marshes of Louisiana’s Mississippi River delta plain affects salt marsh-dependent organisms. This study analyzed three habitat types: Spartina-dominated, Avicennia-dominated, and a mix of the two, focusing on habitat use and …

Examining Anxiety And Achievement Goal Theory In Physical Activity Settings, Timothy Michael Dasinger

LSU Doctoral Dissertations

In the United States (US), a majority of adults do not meet the recommended guides of physical activity despite the many benefits. One benefit of activity is the reduction of anxiety. Although there is robust evidence demonstrating the anxiolytic effects of physical activity, the mechanism is not fully understood. Some psychological explanations are related to a lack of confidence in one’s ability. Because of this, Achievement Goal Theory (AGT) may be a viable framework to explain the anxiolytic effects of physical activity. The focus of this dissertation is to examine the efficacy of AGT as a mechanism and to explore …

Determining Growth Characteristics And Control Programs For Nealley's Sprangletop (Leptochloa Nealleyi Vasey), Trace Buck

LSU Master's Theses

ABSTRACT

Research was conducted at the LSU AgCenter Dean Lee Research and Extension center near Alexandria, La in 2016 and 2017 to evaluate the growth characteristics and control of Nealley’s sprangletop. Nealley’s sprangletop is a relatively new weed with little research available to understand its growth habit and effective control strategies.

Nealley’s sprangletop undergoes a more drastic height increase of 212 to 742 mm, 4 to 6 WAE than Amazon sprangletop 377 to 612 mm in the same time frame. Averaged across harvest interval tiller and leaf number of Nealley’s sprangletop was approximately 50 and 40% less than Amazon sprangletop. …

Characterizing The Physiological Role Of Inward Rectifier Potassium (Kir) Channels In Tick Salivary Gland Function, Zhilin Li

LSU Master's Theses

The tick salivary gland is a critical tissue that enables blood feeding, maintenance of the ionic gradients, and facilitates pathogen transmission. Therefore, the broad objective of this investigation was to leverage pharmacological approaches to investigate the role of potassium ion channels to salivary gland function of Amblyomma americanum in an effort to identify a tractable target site for therapeutic development.

Data collected in Chapter 2 clearly illustrated that the A. americanum salivary gland is reliant upon inward rectifier potassium (Kir) channels for fluid secretion, which was similar to previous work performed by our laboratory on Drosophila salivary gland. Therefore, the …

An Analysis Of Alu Elements In Baboons, Cody James Steely

LSU Doctoral Dissertations

Transposable elements compose a large portion of mammalian genomes and are estimated to make up anywhere from ~45% - ~70% of the human genome. Alu elements are primate-specific retrotransposons that are found in high copy number (> 1 million copies) and are spread throughout the genome. These elements are the most commonly repeated sequence in the human genome and have contributed to a number of disease states in humans. Alu elements are useful markers for population genetics and phylogenetics and have proven valuable in understanding difficult to determine relationships between species and within populations.

Baboons (genus Papio) are spread throughout …

Evolution Of Alu Elements In The Saimiri And Papio Lineages Of Primates, Jasmine Nicole Brown Baker

LSU Doctoral Dissertations

Alu elements are approximately 300 base pair (bp) primate specific non- autonomous retrotransposons. Alu elements, a short interspersed element (SINE), account for high copy numbers in all primate genomes. Numerous Alu element subfamilies have undergone varying degrees of activity and amplification within primates. Identification of these subfamilies has proved to be very informative in elucidating phylogenies and as phylogenomic markers. Squirrel monkeys, genus Saimiri, are one of the most well-known neotropical primates and the second most commonly used laboratory monkey. Squirrel monkey species diverged approximately 1.5 million years ago and are native to South America. Despite being well-known, there …
