The Effects Of Aluminum Concentration On Growth Responses In Six Spartina Alterniflora Genotypes, Daniel Farrell Becker Jan 2005

The Effects Of Aluminum Concentration On Growth Responses In Six Spartina Alterniflora Genotypes, Daniel Farrell Becker

LSU Master's Theses

Elevated soluble aluminum concentrations can adversely affect plant growth. During a drought, wetland soils may experience higher than normal soluble aluminum due to the oxidation of metal sulfides and resulting decreases in pH, which mobilizes metallic cations. Louisiana coastal salt marshes were subject to a record-setting drought in the winter and spring of 2000 which was coincident with the die-off of large expanses of salt marsh, termed " brown marsh ". Spartina alterniflora was the primary plant species affected. However, because some individuals within large areas of die-off survived the brown marsh event, they may have been the more resistant …

Previous studies with the Pacific oyster, Crassostrea gigas, have shown: (1) the need to use the larger eggs of triploid females to …


Genetic Diversity Among Sugarcane Clones Using Target Region Amplification Polymorphism (Trap) Markers And Pedigree Relationships, Jie Alojado Arro Jan 2005

Genetic Diversity Among Sugarcane Clones Using Target Region Amplification Polymorphism (Trap) Markers And Pedigree Relationships, Jie Alojado Arro

LSU Master's Theses

Genetic diversity is indispensable to sustain genetic gain in breeding programs. Cultivated sugarcane is a highly heterozygous hybrid derived from crossing two highly heterozygous parents. Sugarcane breeders traditionally rely on pedigree records to select parents. Molecular markers now make it possible to assess genetic diversity at the DNA level. Sixty three sugarcane clones were characterised using Target Region Amplification Polymorphism (TRAP) markers and pedigree relationship (Coefficient of parentage (COP)). The TRAP is a PCR-based marker with a fixed primer designed from Expressed Sequence Tag (EST) sequences paired with an arbitrary primer. It is supposed to unravel trait based polymorphism in …


The King George Island Mounds Site (16lv22): A Late Archaic Mound Complex Along The Lower Amite River, Fiona Helena Vasbinder Jan 2005

The King George Island Mounds Site (16lv22): A Late Archaic Mound Complex Along The Lower Amite River, Fiona Helena Vasbinder

LSU Master's Theses

The King George Island Mounds site (16LV22) is one of four conical mound sites located along the lower Amite River in Livingston Parish, Louisiana. Gagliano originally reported the site in 1957 as containing two conical mounds. Initially, it was postulated that the Lower Amite River mounds might date to the Marksville period based on the similarities of shape. Recent research conducted at the site indicates that the site may contain up to five conical mounds that date to the Late Archaic period. Geomorphological, pedological, and archaeological data indicate an initial Archaic occupation. Archaic period artifacts were recovered from excavations above, …

Associations Of Avian And Herpetofauna Communities With Forest Management At Multiple Spatial Scales, Holly Grace Legrand

LSU Master's Theses

Decline of amphibians, reptiles, and numerous Neotropical migrant birds has been attributed to habitat destruction and alteration, which warrants examination of these groups in managed forests and their association with habitat characteristics at multiple spatial scales. We surveyed avifauna and herpetofauna communities in 3 managed forests in Louisiana during 2003-2004. Study areas included Sherburne Wildlife Management Area (WMA), a bottomland hardwood forest under uneven-aged management, Ben’s Creek WMA, an even-aged, short-rotation loblolly pine plantation, and Sandy Hollow WMA, a longleaf pine-savannah maintained with prescribed fire. Field techniques included surveys consisting of avian point counts, drift fence arrays (PFFT), cover boards, …


Castle To Condo, Country To Corporation: What Becomes Of Hamlet In Almereyda's Modern World, Melissa Trosclair Daigle Jan 2005

Castle To Condo, Country To Corporation: What Becomes Of Hamlet In Almereyda's Modern World, Melissa Trosclair Daigle

LSU Master's Theses

This paper looks into the inner workings of Michael Almereyda's Hamlet (2000). Even though Almereyda updates the setting and cuts many of the lines, sometimes entire scenes, from the source text, he is able to convey the some of the themes through his use of technology and media. While some themes do transfer into the postmodern setting, the places of discord are most interesting. Of particular interest is his use of modern technologies to display the corruption found in Shakespeare's play. These technologies, including speakerphone, surveillance equipment, wiring devices, handheld camcorders, and still photography, create an atmosphere of both continual …

Molluscan Taphonomy As A Proxy For Recognizing Fossil Seagrass Beds, Jill Suzanne Leonard-Pingel Jan 2005

Molluscan Taphonomy As A Proxy For Recognizing Fossil Seagrass Beds, Jill Suzanne Leonard-Pingel

LSU Master's Theses

Seagrass beds, important marine ecosystems both economically and environmentally, have a poor fossil record. As a result, little is known about the geographic distribution of seagrasses over historic and geologic time, or their abundance when unaltered by anthropogenic effects. The purpose of this study is to define a taphonomic signature unique to seagrass beds that can be used as a proxy for identifying the seagrass habitat in the fossil record. In order to develop this proxy, sediment samples from Recent seagrass and non-seagrass environments were collected, and the molluscan bioclasts from these samples were categorically ranked for the following taphonomic …

Matrix Metalloproteinase 3, Matrix Metalloproteinase 13, And Tissue Inhibitor Of Metalloproteinase 1 Concentrations In Normal And Naturally-Occurring Osteoarthritic Canine Stifles, Blaine Allen Burkert

LSU Master's Theses

Osteoarthritis is arguably the most common ailment in both dogs and people in the developed World. Treatment for osteoarthritis is currently symptomatic. Development of therapies designed at stopping the progression of osteoarthritis, require a method of evaluating efficacy. Objective analysis by measuring joint metabolism via clinical trials of the cross-over design is currently not possible with the methods utilized. Extracellular matrix degradation is a hallmark of osteoarthritis. The matrix metalloproteinases are major degradative enzymes. There are currently no commercially available assays to measure canine matrix metalloproteinases. Human and canine matrix metalloproteinases are highly homologous. The use of antibodies and assays …


Racial Variations And Social Support And Its Impact On Stress And Depression, Claire Sam Jan 2005

Racial Variations And Social Support And Its Impact On Stress And Depression, Claire Sam

LSU Master's Theses

Evidence suggests that social support can mitigate some of the harmful effects of stress on health. Social support theorists argue that certain social groups have differential access to social support; therefore, certain social groups are at a higher risk of experiencing psychiatric symptoms. Although social networks are beyond the scope of these analyses, it is an important component to consider when examining the uneven distributions of social support between social groups. If racial differences exist in the networks in which individuals are embedded, then part of the differential access to social support could be explained by examining the various compositions …


Environmental Benefits Realized From Eradication Of The Non-Indigenous Insect Anthonomus Grandis Boheman, The Cotton Boll Weevil, Marc Stephen Bordelon Jan 2005

Environmental Benefits Realized From Eradication Of The Non-Indigenous Insect Anthonomus Grandis Boheman, The Cotton Boll Weevil, Marc Stephen Bordelon

LSU Master's Theses

At least one third of the insecticide used in agriculture has been used to control the boll weevil in cotton. Historically, these insecticides have been toxic to humans and harsh on the environment. In addition, the intensive use of chemical insecticides to control the boll weevil results in the disruption of naturally occurring biological control factors that regulate other insect pest populations causing a chain reaction of secondary pest populations that require treatment followed by resurgence and repeat treatment. This situation has resulted in the development of resistance to insecticides, high control costs and unacceptable levels of chemical insecticide contamination …

Antimicrobial Effect Of Cetylpyridinium Chloride Against Listeria Monocytogenes Growth On The Surface Of Raw And Cooked Shrimp, Tracie Michelle Dupard Jan 2005

Antimicrobial Effect Of Cetylpyridinium Chloride Against Listeria Monocytogenes Growth On The Surface Of Raw And Cooked Shrimp, Tracie Michelle Dupard

LSU Master's Theses

Listeria monocytogenes has emerged as a major foodborne pathogen for the seafood industry due to its psychrotrophic nature and its ubiquitous presence. It has been isolated from soil, sewage, dead vegetative matter, aquatic environments, fecal material, fish, crustaceans, and domesticated animals. As a result, L. monocytogenes has been responsible for several shrimp recalls and has been epidemiologically linked to human listeriosis. Fresh seafood products are highly perishable and their shelf-life is limited by microbiological spoilage. Therefore, when pathogenic microorganisms are involved, it poses a health threat to the general public. The situation is further complicated because seafood processing plants are …

Visualization Based On Interactive Clipping: Application To Confocal Data, Gaurav Khanduja Jan 2005

Visualization Based On Interactive Clipping: Application To Confocal Data, Gaurav Khanduja

LSU Master's Theses

We have explored how clipping can be exploited in an interactive manner to visualize massive three-dimensional datasets. In essence, the proposed interactive clipping approach involves the dynamic adjustment of the clipping plane to expose any cross-section of the volume data and subsequent adjustment of the clipped surface to the best view position using a combination of rotation and translation. The thesis describes the design, implementation and application of our interactive-clipping-based visualization system. The implementation is done with OpenGL and C++, thus resulting in a highly portable and flexible system. For illustration, two types of scientific datasets, confocal data of a …

This Is What I Meant When I Told You, Ryan David O'Malley

LSU Master's Theses

THIS IS WHAT I MEANT WHEN I TOLD YOU is a quest to visually decipher the complexities of "self." The goal is to form a relationship of honesty between my mind and my hand, the art and the viewer. The work investigates reoccurring ideas, threaded through each day, in order to create narratives based on the immediacy of emotion, and the struggle between self-realization and uncertainty. Or as one commented during my show, "A celebration of the dark side of life."


Sinker Cypress: Treasures Of A Lost Landscape, Christopher Aubrey Hurst Jan 2005

Sinker Cypress: Treasures Of A Lost Landscape, Christopher Aubrey Hurst

LSU Master's Theses

Sinker cypress (Taxodium spp.) logs are timbers that were lost during transit from harvest locations in the swamps and mill sites during the industrial cypress harvest from 1880-1930. A small industry has developed, concentrated on the recovery of sinker logs. Most of the persons involved in the recovery of sinker cypress, mill the logs into lumber, and sell the timber directly to consumers or to distributors. A smaller number of pullers retain the logs for personal use. Recovery operations are a costly endeavor and require a significant investment on the part of the harvesters. Most pullers are owner/operators who do …
