Taphonomy And Sedimentology Of Two Miocene Vertebrate Fossil Sites On Fort Polk, Louisiana, Julie Lynn Hill Jan 2010

Taphonomy And Sedimentology Of Two Miocene Vertebrate Fossil Sites On Fort Polk, Louisiana, Julie Lynn Hill

LSU Master's Theses

The discovery of a terrestrial mammalian fauna in the Miocene deposits on Fort Polk, Louisiana, fills a geographic gap in the Gulf Coast paleontological framework, but the provenance of the fossils, nature of the depositional environments, and relationships between the sites is still debated. This is especially true for the TVOR site cluster. TVOR SE has a mixture of marine and terrestrial vertebrates in association with a partly dissolved, in situ bed of articulated oyster shells, which stands in contrast to the fully terrestrial and freshwater assemblage at TVOR, and the indeterminate site TVOR S. Although limited outcrop may bias …

Identifying Historic Storm Surges And Calculating Storm Surge Return Periods For The Gulf Of Mexico Coast, Hal Needham Jan 2010

Identifying Historic Storm Surges And Calculating Storm Surge Return Periods For The Gulf Of Mexico Coast, Hal Needham

LSU Master's Theses

Tropical cyclone-generated storm surges inflict natural disasters that are among the most catastrophic globally. The surges observed along the U.S. Gulf of Mexico are among the highest in the world, second only to the Bay of Bengal. Storm surge activity along the U.S. Gulf Coast remains poorly understood, however, in part, due to the absence of credible research that accurately depicts the maximum height and location of historic surge events. This research addresses this gap in the scientific literature by creating a database of storm surge observations along the Gulf Coast between the years 1880 to 2009. A total of …

Dopaminergic Input To The Equine Pituitary: Seasonal And Estradiol Effects, Sarah Case Clavier Jan 2010

Dopaminergic Input To The Equine Pituitary: Seasonal And Estradiol Effects, Sarah Case Clavier

LSU Master's Theses

Two experiments were conducted to study the effects of season and estradiol administration on dopaminergic input to the equine adenohypophysis. Experiment 1 began in the spring with 8 mares and 8 stallions and was repeated again in the summer, fall, and winter. Horses were given sulpiride injections of eight incremental doses (0.25 to 32 µg/kg BW). Within each group of 8 horses, half received the sulpiride in an increasing manner, the other half in a decreasing manner. Prolactin concentrations peaked in the first 15 to 30 min in all horses in all seasons. Prolactin areas under the curve increased (P < 0.001) with increasing doses of sulpiride, and were highest (P < 0.05) in March for stallions, but in June for mares. The calculated half-maximum values, which should be proportional to the dopaminergic input to the pituitary, were lowest (P < 0.05) in June and greatest in September. The variation in half-maximum values with season indicated a change in dopaminergic input to the pituitary, with lowest input occurring in June in both sexes. Experiment 2 was designed to determine if the degree of dopaminergic input to the adenohypophysis is altered by estradiol administration. Twelve geldings were used. On day 0, geldings received an i.m. injection of either estradiol cypionate (ECP; n = 6) or vegetable oil (n = 6) at one of two dose volumes (2 vs. 10 mL). On day 6, all geldings received an injection of sulpiride at 0.082 µg/kg BW in saline. Sulpiride injections were repeated every other day with the dose increasing each day, from 0.164 to 100 µg/kg BW. Estradiol pretreatment increased (P < 0.05) the prolactin response to sulpiride at the 2.56 µg/kg dose and higher. However, the half-maximum values for ECP-treated and control geldings did not differ, indicating that the amount of sulpiride needed to counterbalance the amount of dopamine reaching the pituitary was unaltered by estradiol treatment. It was concluded that estradiol likely stimulates prolactin production and secretion after sulpiride directly at the lactotrope level, rather than by decreasing hypothalamic dopamine input to the lactotropes.

The Ornamentation Of Brunelleschi's Old Sacristy Of San Lorenzo In Florence, Jessica Lynne Clinton Jan 2010

The Ornamentation Of Brunelleschi's Old Sacristy Of San Lorenzo In Florence, Jessica Lynne Clinton

LSU Master's Theses

The Old Sacristy of San Lorenzo in Florence, Italy, was constructed during the years 1419-1428 and is considered one of the most influential buildings of the early Italian Renaissance. Brunelleschi's Old Sacristy, in its original design, was pristine and void of the architectural ornamentation that had come to characterize so many buildings that preceded it and which would come to be associated with the sacristy itself on account of later alterations. Indeed, the original sacristy was characterized by a purely articulated space free of additional ornamentation to the architecture. However, shortly after the termination of construction, the Old Sacristy became …

The Influence Of Two Estrogens On The Sex And Ovarian Development Of Eastern Oysters (Crassostrea Virginica) Maintained In A Closed Recirculating System, Wesley Michael Burnside Jan 2010

The Influence Of Two Estrogens On The Sex And Ovarian Development Of Eastern Oysters (Crassostrea Virginica) Maintained In A Closed Recirculating System, Wesley Michael Burnside

LSU Master's Theses

As a multi-million dollar industry, production of the eastern oyster Crassostrea virginica is significant to the economy of the nation’s coastal regions. The cost of commercial oyster aquaculture has higher inputs than the oyster fishery, but larger, better quality oysters can be produced for culture by the stable availability of triploid individuals.

The goal of this project was to determine if the use of an estrogen, estradiol-17β or estradiol-3-benzoate, at a consistent environmental temperature would increase the percentage of females in a population, as well as ovarian development of eastern oysters. Ultimately, this could be applied to triploids to increase …

The Interactions Between Sentence Complexity, Working Memory, And Additional Working Memory Load: An On-Line Measure, Christy Seidel Jan 2010

The Interactions Between Sentence Complexity, Working Memory, And Additional Working Memory Load: An On-Line Measure, Christy Seidel

LSU Master's Theses

This experiment takes an on-line look at syntactical complexity, external loads, and working memory, and how the three influence one another. Based on off-line data looking at the interactions between these three factors, we have discovered that syntactic complexity and span have main effects, while the effect of load is most interestingly seen in a three way interaction representing the hardest possible combination of factors. Through this new design, we were able to see whether the off-line results of sentence processing are replicated with an on-line measure. Our new off-line findings replicate past results, which show that working memory impacts …

Stereotype And Representation Of Near And Middle Eastern Peoples In La Bande Dessinee, Brandon Matthew Thomas Jan 2010

Stereotype And Representation Of Near And Middle Eastern Peoples In La Bande Dessinee, Brandon Matthew Thomas

LSU Master's Theses

Representation of social groups in the comics is serious. In 2006, a series of twelve cartoons published in a Danish newspaper sparked a controversy that precipitated the deaths of hundreds of people. The images depicted Mohammed and other images that supposedly mocked Islam. All across Europe, the Middle East, and North Africa protesters paraded through the streets, some calling for the death of the cartoonists. Trials in Europe over the publication of these cartoons resulted in several firings. Counter protests have also arisen. These protesters found grievance with the firings, claiming that the freedom of the press was being violated …

Multi-Scale Habitat Associations Of Shorebirds During Spring Migration In Southwestern Louisiana Rice Fields, Rachel K. Villani Jan 2010

Multi-Scale Habitat Associations Of Shorebirds During Spring Migration In Southwestern Louisiana Rice Fields, Rachel K. Villani

LSU Master's Theses

Rice is the most common wetland crop in the world, and important for waterbirds and shorebirds worldwide, including the United States. In Louisiana, shorebirds use rice fields during spring migration, and are an important for foraging and refueling during migration. However, competing land uses and restoration projects may reduce the availability of rice fields, and impact the landscape that shorebirds use during migration. To determine how shorebirds use the landscape, I evaluated local and landscape factors affecting shorebird use of rice fields during spring migration in southwestern Louisiana. Using five habitat suitability zones (HSZs) based on rice density and canopy …

Detect Live Salmonella Cells In Produce By Coupling Propidium Monoazide With Loop-Mediated Isothermal Amplification (Pma-Lamp), Siyi Chen Jan 2010

Detect Live Salmonella Cells In Produce By Coupling Propidium Monoazide With Loop-Mediated Isothermal Amplification (Pma-Lamp), Siyi Chen

LSU Master's Theses

Salmonella is a leading cause of foodborne illnesses worldwide. In recent years, an increasing number of Salmonella-related outbreaks in produce has been reported. It is therefore important that the produce industry be equipped with rapid, sensitive, specific detection methods for live Salmonella cells in produce to better ensure the produce safety. In this study, we first designed and optimized a loop-mediated isothermal amplification (LAMP) assay for Salmonella detection by targeting the invasion gene (invA). Then we incorporated a chemical reagent, propidium monoazide (PMA) into the sample preparation step to prevent LAMP amplification of dead Salmonella cells. To our knowledge, this …

Water And Solute Transport In The Shallow Subsurface Of A Riverine Wetland Natural Levee, April Elea Newman Jan 2010

Water And Solute Transport In The Shallow Subsurface Of A Riverine Wetland Natural Levee, April Elea Newman

LSU Master's Theses

In riverine wetlands, the rate and magnitude of water exchanged between river channels and adjacent wetlands have a major influence on hydrologic function and associated aquatic habitat and water quality. River channels are generally separated from backswamps by natural levees; however, preferential flow may allow potentially substantial water and solute exchange between them. Determining the influence of preferential flow on water and solute transport in natural levees requires an innovative approach that allows measurement of transport rates at a scale large enough to capture field-scale variability. To test the hypothesis that preferential flow is important to subsurface water movement through …

Cell Extract-Based Reprogramming Of Somatic Cells, Laura Whitney Coley Jan 2010

Cell Extract-Based Reprogramming Of Somatic Cells, Laura Whitney Coley

LSU Master's Theses

The differentiation potential of adult stem cells (ASC) has long been thought to be limited to cell lineages present in the organ from which they are derived; however, several studies have challenged this notion by demonstrating that some ASC exhibit a remarkably high degree of plasticity. Unlike terminally differentiated somatic cells, the less differentiated state of ASC can assume the functional phenotypes and expression profiles of cells unique to other tissues. The expansive repertoire of differentiation potential exhibited by ASC suggests these cells possess characteristics similar to pluripotent cells, including epigenomic regulatory pattern. Therefore, ASC may be better equipped for …

Hepatotoxic Cyanobacterial Blooms In Louisiana's Estuaries: Analysis Of Risk To Blue Crab (Callinectes Sapidus) Following Exposure To Microcystins, Ana Cristina Garcia Jan 2010

Hepatotoxic Cyanobacterial Blooms In Louisiana's Estuaries: Analysis Of Risk To Blue Crab (Callinectes Sapidus) Following Exposure To Microcystins, Ana Cristina Garcia

LSU Master's Theses

The most common toxins detected following freshwater harmful algal blooms are microcystins, a group of hepatotoxins produced by cyanobacteria (e.g., Microcystis and Anabaena spp.). Preference for filter-feeding prey, including bivalves, makes the blue crab, Callinectes sapidus, vulnerable to microcystin contamination and makes the commercially important crab a potential vector of microcystins. I used a combination of field and laboratory studies to determine blue crab vulnerability to microcystin contamination and consequent impacts on crab physiology. Samples collected from a hyper-eutrophic freshwater lake, Lac des Allemands, Louisiana, were analyzed for cyanobacterial abundances and microcystins in surface water and blue crabs using light-microscopy …

Using Algae To Estimate Postmortem Submersion Interval In A Louisiana Bayou, Sophia Renke Jan 2010

Using Algae To Estimate Postmortem Submersion Interval In A Louisiana Bayou, Sophia Renke

LSU Master's Theses

While algae are often used in forensic science for the determination and confirmation of death by drowning, their utility for the estimation of postmortem submersion interval (PMSI) has been underutilized. Algae are present in all water systems and will grow upon decomposing matter; yet, very little published literature exists on their use in PMSI estimation. Because PMSI is difficult to predict due to the variable nature of water, the reaction of the submerged body within water, and the lack of truly sarcophagous aquatic insects, algae are a potentially invaluable tool for the forensic anthropologist. This research investigates the utility of …

Using Inoceramid Bivalve Taphonomy As A Paleoenvironmental Indicator Across The Cenomanian/Turonian Horizon At The Pueblo, Colorado Gssp, Jacob Frederick Grosskopf Jan 2010

Using Inoceramid Bivalve Taphonomy As A Paleoenvironmental Indicator Across The Cenomanian/Turonian Horizon At The Pueblo, Colorado Gssp, Jacob Frederick Grosskopf

LSU Master's Theses

Recent paleoenvironmental and geochemical studies indicate that benthic conditions during Oceanic Anoxic Event II (OAE II) (93.5 Mya) in the Cretaceous Interior Seaway (CIS) were dysoxic rather than anoxic. In this thesis, dysoxic benthic conditions were tested for by observing patterns in taphonomic alteration of the calcite portions of inoceramid bivalve shells during and after OAE II. Inoceramid valves were extracted from beds that spanned OAE II at the Cenomanian/Turonian Global Boundary Stratotype Section and Point (GSSP) in Pueblo, Colorado: beds 62 (Hartland Shale), 72 (Bridge Creek Limestone), and 115 (Bridge Creek Limestone). Degree of alteration was tallied using categorical …
