Comparison Of Land Building By Mississippi River Diversion Using One And Two Dimensional Numerical Models, Gyan Prasad Basyal Jan 2014

Comparison Of Land Building By Mississippi River Diversion Using One And Two Dimensional Numerical Models, Gyan Prasad Basyal

LSU Master's Theses

River sediment diversions have been identified as one strategy for creating new land and offsetting Mississippi River delta plain land loss. Numerical modeling is one tool for estimating the amount of land, geomorphic features and ecological benefits from diversions. There are a number of models proposed to estimate sediment diversion land building, ranging from simplistic approaches that provide bulk characteristics and use little computational resources to process-based models that require a large amount of input parameters and computing power. This thesis aims to compare and contrast two approaches to simulating the land building processes in a simplified receiving basin: a …

Adapting Resilience To A New Hazard: Oil And Oysters In Coastal Louisiana, Audrey Maass Jan 2014

Adapting Resilience To A New Hazard: Oil And Oysters In Coastal Louisiana, Audrey Maass

LSU Master's Theses

Inherently resilient practices are one mechanism that communities engage in to cope with disruptive events. A community retains and passes down the practices associated with inherent resilience in their collective memory. The inherent resilience of a community is developed over time, yet the explanation provided by Colten et al. lacks a genesis of how this process developed particularly in relation to the oil industry’s entry into Louisiana. The foundations of these practices will be explored through historic court documents to find encounters between oystermen and oil spills. In addition to legal resources, I also investigate newspaper articles and other historic …

Natural Isoscapes Of Louisiana: Stable Isotope Analysis Of Oxygen, Carbon, And Strontium, Miley Jackson Jan 2014

Natural Isoscapes Of Louisiana: Stable Isotope Analysis Of Oxygen, Carbon, And Strontium, Miley Jackson

LSU Master's Theses

Stable isotope analysis has been used by archaeologists and anthropologists to better understand time, provenience, and diet of past humans, but the utility of stable isotope analysis in modern humans has not been fully explored. Forensic anthropologists today primarily identify human skeletal remains, and stable isotope analysis of bone may narrow down the possible identities of an individual. Determining the natural variability within the state of Louisiana is the first step in determining whether individuals from different areas of the state are distinguishable from one another. This thesis investigated the natural isotopic variability in Louisiana with respect to oxygen (δ18O), …

Inferences Of Subsistence Activities Using Musculoskeletal Stress Markers Of Humerii From Two Louisiana Archaeological Populations, Brian M. Thibodeaux Jan 2014

Inferences Of Subsistence Activities Using Musculoskeletal Stress Markers Of Humerii From Two Louisiana Archaeological Populations, Brian M. Thibodeaux

LSU Master's Theses

Wolff’s Law states that bone is laid down where it is needed; therefore, mechanical factors, including subsistence-based activity patterns, play a role in bone biology. One of bone’s responses to strain is the development of musculoskeletal stress markers (MSMs) at entheses, or the sites in which soft tissues, including tendons and ligaments, attach to bone. MSMs have been used by bioarchaeologists to make inferences about past population’s activity patterns and subsistence behaviors. The following study scores eight MSMs of the proximal humerii from the Tchefuncte (16ST1) and Greenhouse (16AV2) sites in Louisiana. The MSMs were segregated into muscle groups and …

Biogeochemical Controls On Biodegradation Of Mc252 Crude Oil In Coastal Wetland Systems, Matthew Paul Rodrigue Jan 2014

Biogeochemical Controls On Biodegradation Of Mc252 Crude Oil In Coastal Wetland Systems, Matthew Paul Rodrigue

LSU Master's Theses

Weathering of MC252 oil from the Deepwater Horizon oil spill is taking place in coastal Louisiana marsh and mangrove wetland systems. Alkylated phenanthrenes and dibenzothiophenes, which are the most prominent PAHs found at MC252 contaminated sites, are weathering at rates up to 5% per year relative to alkylated chrysenes 3 years after initial oiling. Flux chambers at marsh locations trapped CO2 that exhibited δ13C signatures lower than indigenous organic matter signifying hydrocarbon mineralization to CO2. Weathering rates at each of these locations are heavily influenced by the biogeochemistry of the surrounding environment. High-resolution nutrient profiles were obtained at different locations …

Factors Influencing Adoption Of Vsh Queens In The Honey Breeding Industry, Julie Leiby Jan 2014

Factors Influencing Adoption Of Vsh Queens In The Honey Breeding Industry, Julie Leiby

LSU Master's Theses

There are many threats that contribute to the decline in honey bee colonies around the United States; among them is the Varroa mite, Varroa destructor. The Varroa mite is a significant threat to honey bees and, by extension, beekeepers across the United States. It is suspected to be one of the main contributors to the increase in colony collapse and the decline in bee numbers and the beekeeping industry (Danka, May 2013). Fifty-five percent of beekeepers exited beekeeping between 1987 and 2002 (USDA). Although honey production continued to decrease through 2007, the number of beekeepers entering beekeeping had increased (USDA). …

Effects Of Latitude On The Competitive Ability Of Native And Invasive Genotypes Of Phragmites Australis, Anthony K. Chow Jan 2014

Effects Of Latitude On The Competitive Ability Of Native And Invasive Genotypes Of Phragmites Australis, Anthony K. Chow

LSU Master's Theses

One commonly cited mechanism for the success of invasive species is their superior competitive ability relative to that of native species. Although 88% (22 of 25) of the empirical studies support the prediction that the strength of competition for native species increases with latitude, no studies to date have compared the competitive ability of native and co-occurring invasive species across a broad latitudinal range. In a greenhouse, I investigated whether the competitive ability of North American native and European invasive haplotypes of Phragmites australis vary with latitude. Another widespread, non-indigenous haplotype, the Gulf Coast haplotype, was also included for assessment …

The Effect Of Hydrocarbon Contamination And Substrate Material On Oyster Reef Commensal Communities, Jenessa Lea Kay Jan 2014

The Effect Of Hydrocarbon Contamination And Substrate Material On Oyster Reef Commensal Communities, Jenessa Lea Kay

LSU Master's Theses

Oyster reefs in the Gulf of Mexico provide water quality enhancement, shoreline stabilization, carbon sequestration, and facilitate spat recruitment. They are also essential refuges for numerous resident fish and invertebrates, in turn supporting commercial fisheries. Oyster reefs are however in danger worldwide as oyster fisheries increase and pollution from oil spills, such as the Deepwater Horizon spill further degrade reefs. The development of artificial reefs has therefore become a necessity. This study assesses both the long-term and acute response of oyster reef commensal communities to hydrocarbon contamination, as well as comparing the efficacy of artificial reef substrates for restoring these …

A Quantitative And Molecular Evaluation Of Calves Sired By Three Different Breeds For Growth, Performance, And Carcass Traits, Malcolm Seth Mizell Jan 2014

A Quantitative And Molecular Evaluation Of Calves Sired By Three Different Breeds For Growth, Performance, And Carcass Traits, Malcolm Seth Mizell

LSU Master's Theses

The first objective of the two studies in the research herein was to evaluate growth, performance and carcass quality and composition traits from a group of spring born calves sired by Charolais, Braunvieh, or Simmental bulls. Growth traits analyzed included birth weight (BW), weaning weight (WW), and hip height (HH). Carcass quality and composition traits analyzed included hot carcass weight (HCW), rib eye area (REA), back fat thickness (BF), marbling score (MS), and yield grade (YG). Analysis revealed Simmental sired calves were significantly heavier (P<.05) at birth when compared to Charolais and Braunvieh sired calves. Braunvieh sired calves were reported to be significantly (P<.05) shorter than Simmental sired calves for hip height. Hot carcass weight analysis revealed that Charolais sired calves were significantly (P<.05) heavier when compared to Braunvieh sired calves. No individual sire breed group displayed any significant differences for weaning weight, rib eye area, back fat thickness, marbling score, or yield grade. The second objective was evaluate potential SNP associations on four candidate genes with growth, performance, and carcass composition traits in a population of crossbred steers sired by Charolais, Braunvieh, and Simmental bulls. Traits analyzed for growth, performance, and carcass traits were previously mentioned. Analysis was performed on 38 steer calves. Single nucleotide polymorphisms within four candidate genes including Thyroglobulin (TG), Adiponectin (ADPOQ), Insulin like growth factor-1 (IGF-1), and Calpastatin (CAST) were chosen for analysis. A total of 14 SNP on TG, ADPOQ, CAST, and IGF-1 genes were significantly associated with birth weight and weaning weight. Analysis revealed 13 SNP on TG, ADPOQ, IGF-1, and CAST genes significantly associated (P<.05) with HCW, BF, MS, and YG. No markers were reported to be significantly associated (P<.05) with HH or REA. A total of 11 markers with 3 markers located on the ADPOQ gene, 1 marker located on the IGF-1 gene, 3 markers located on the TG gene, and 5 markers located on the CAST gene were significantly associated with both growth and carcass traits.

Production, Discard, And Urban Life At The Early Horizon Center Of Caylán, Coastal Peru, Jacob Pate Warner Jan 2014

Production, Discard, And Urban Life At The Early Horizon Center Of Caylán, Coastal Peru, Jacob Pate Warner

LSU Master's Theses

In this thesis I examine material production, discard, and trash flow at the Early Horizon urban center of Caylán (800 – 1 cal. BC) on the Peruvian North-Central coast. Trash (or garbage, refuse, litter, or waste) is a central source of information for archaeologists examining prehistoric lifeways in Peru. Despite frequent use of trash as a source for radiocarbon samples, cultural material, and dietary evidence, few studies utilize the transportation and concentration of trash to examine human behavioral patterns. The Early Horizon, as a transitional period in Peruvian prehistory, presents an opportunity to test the utility of trash deposits in …

Effects Of Salinity And Temperature On Bioelectrical Impedance Analysis Of Gulf Killifish, Fundulus Grandis, Shea A. Miller Jan 2014

Effects Of Salinity And Temperature On Bioelectrical Impedance Analysis Of Gulf Killifish, Fundulus Grandis, Shea A. Miller

LSU Master's Theses

Bioelectrical impedance analysis (BIA) has been proposed as an easy and accurate technique for a non-lethal index of condition in fish; however, factors affecting its accuracy have yet to be properly identified. The technique uses the resistance (R) and reactance (Xc) of water and lipids in contiguous tissues to estimate lipid content. Studies have investigated the use of BIA on fish, but with mixed results, possibly caused by unrecognized sources of influences. Our study explored possible sources of variance for BIA measurements in gulf killifish, Fundulus grandis, through laboratory feeding and fasting experiments, and experimental exposures to acute changes in …

Effect Of Tissue Source On Adult Equine Multipotent Stromal Cell Pluripotency Induction Treatment With Synthetic Mrna, Javier Martin Jarazo Jan 2014

Effect Of Tissue Source On Adult Equine Multipotent Stromal Cell Pluripotency Induction Treatment With Synthetic Mrna, Javier Martin Jarazo

LSU Master's Theses

Autogenous and autologous adult multipotent stromal cells are applied to treat equine musculoskeletal injuries in clinical practice. However, options for autologous therapy in the equine specie are restricted due to the limited biological material obtained or MSCs tissue harvest procedure and because of their unpredictable in vivo behavior. Induced pluripotent stem cells represent an alternative to overcome these limitations. Traditionally, iPSCs are produced by introducing DNA for early embryonic genes into cells with viruses. The method tested in this study, avoids the use of viral vectors and potential for exogenous DNA integration into the cell’s genome by utilizing a lipid …

Polonium-210 Dynamics In The Northern Gulf Of Mexico, Patrick Robert Jones Jan 2014

Polonium-210 Dynamics In The Northern Gulf Of Mexico, Patrick Robert Jones

LSU Master's Theses

Polonium-210 (t1/2=138 d) is the most common among the 33 known radioisotopes of Polonium found in the natural environment. It is produced by the radioactive decay of its long-lived grandparent Lead-210(t1/2=22.3 d) via Bismuth-210 (t1/2=5.012 d) and forms as part of the natural Uranium-238 decay series. The primary hazard associated with Polonium-210 is its radioactivity, as an alpha particle emitter. Marine organisms receive their maximum radioactive dose in the natural environment from Polonium-210. Polonium has been known to bioaccumulate in the marine food web and can be potentially harmful to humans via the intake of certain marine organisms. Thus it …
