Evaluation Of Growth Rates And Establishment Patterns Of Water-Elm (Planera Aquatica) And Baldcypress (Taxodium Distichum) In Response To Hydrologic And Climatic Conditions At Catahoula Lake, Louisiana, Sanjeev Joshi Jan 2012

Evaluation Of Growth Rates And Establishment Patterns Of Water-Elm (Planera Aquatica) And Baldcypress (Taxodium Distichum) In Response To Hydrologic And Climatic Conditions At Catahoula Lake, Louisiana, Sanjeev Joshi

LSU Master's Theses

Hydrologic alterations frequently lead to vegetation changes in floodplain ecosystems. In Louisiana, there has been an expansion of water-elm (Planera aquatica) and to a lesser extent baldcypress (Taxodium distichum) at Catahoula Lake, a Ramsar Wetland of International Importance. Water-elm and baldcypress both are flood tolerant species; baldcypress growth is known to be influenced by hydrologic conditions more than climate. The expansion of these woody trees has reduced herbaceous vegetation valuable for waterfowl. In this study, I tested two hypotheses that establishment of water-elm trees into the lake increased after the construction of water control structures in the nearby Black River …


Habitat- And Region-Specific Reproductive Biology Of Female Red Snapper (Lutjanus Campechanus) In The Gulf Of Mexico, Dannielle Helen Kulaw Jan 2012

Habitat- And Region-Specific Reproductive Biology Of Female Red Snapper (Lutjanus Campechanus) In The Gulf Of Mexico, Dannielle Helen Kulaw

LSU Master's Theses

This study compares reproductive biology estimates of female red snapper among three habitat types (natural shelf-edge banks, standing petroleum platforms and toppled petroleum platforms) and among six regions in the Gulf of Mexico (central Florida, northwest Florida, Alabama, Louisiana, north Texas and south Texas). In both studies, batch fecundity and spawning frequency increased with length, weight and age, and batch fecundity was best correlated with maternal length. Gulf-wide, 75% maturity was achieved by age-3 and 100% maturity was reached by age-8. Sizes- and ages-at-maturity differed among habitat types and regions. Females from natural habitat reached 50% maturity the slowest (age-5, …


Nitrogen Biogeochemistry In A Restored Mississippi River Delta: A Modeling Approach, Benjamin Lee Branoff Jan 2012

Nitrogen Biogeochemistry In A Restored Mississippi River Delta: A Modeling Approach, Benjamin Lee Branoff

LSU Master's Theses

There is evidence that significant reductions (about 50%) in surface water nitrate concentrations within coastal deltaic wetlands receiving diverted Mississippi River water can be contributed to denitrification. Yet there is also contrasting evidence that other processes could be responsible for this nitrate reduction. As Louisiana plans the implementation of major Mississippi River sediment diversions, a thorough understanding of nitrogen dynamics is necessary to reduce risks of coastal eutrophication and offshore hypoxia. A mechanistic numerical computer model has been developed to simulate nitrogen biogeochemistry within the wetlands of the prograding Wax Lake Delta. This model is calibrated to observed fluxes within …


Spatial Variation Analysis Of Salinity To Determine Fluid Flow Pathways And Reservoir Compartmentalization In A Deepwater Gulf Of Mexico Field, William Jacob Daugherty Jan 2012

Spatial Variation Analysis Of Salinity To Determine Fluid Flow Pathways And Reservoir Compartmentalization In A Deepwater Gulf Of Mexico Field, William Jacob Daugherty

LSU Master's Theses

Variations in salinity have been documented in previous studies onshore Louisiana in the Wilcox group (Funayama and Hanor 1995) as well as offshore Louisiana on the continental shelf (Bruno and Hanor 2003 and Steen et al. 2011). These studies were conducted using various methods to estimate pore water salinity and make inferences about possible fluid flow pathways and compartmentalization of reservoirs in order to better understand the complex hydrogeology of the Gulf of Mexico. Similar variations in salinity were documented in this study located in a deepwater salt withdrawal minibasin located on the upper slope of the Gulf of Mexico. …


Do Learning Logs Have An Impact On The Conceptual Mastery Of Force And Motion?: Subtitle, John Arthur Underwood Jan 2012

Do Learning Logs Have An Impact On The Conceptual Mastery Of Force And Motion?: Subtitle, John Arthur Underwood

LSU Master's Theses

This two-week study was conducted to investigate the impact Learning Logs have on student conceptual mastery of force, motion, and kinematics. To begin the study a sample of 554 ninth grade students were selected from a suburban public school in Louisiana. The students were randomly divided into experimental and control groups within four teachers’ classrooms. This distribution was to examine the impact of Learning Logs regardless of the teaching style or time of day. Upon the study’s conclusion there was no significant differences noted due to teaching style or time of day. The Force Motion Concept Evaluation (FMCE) was used …


What Does The ¹⁴C Method For Estimating Photosynthetic Rates In The Ocean Really Measure?, Shaofeng Pei Jan 2012

What Does The ¹⁴C Method For Estimating Photosynthetic Rates In The Ocean Really Measure?, Shaofeng Pei

LSU Doctoral Dissertations

The 14C method has been used extensively by both limnologists and oceanographers to measure photosynthetic rates in aquatic systems, and the large database of 14C measurements that now exists is the ground truth with which satellite algorithms for estimating marine photosynthetic rates on a basin and global scale have been calibrated. However, disconcerting uncertainties still remain with respect to whether and under what circumstances the 14C method provides an estimate of net or gross photosynthesis, or something in between. My study combined batch and continuous culture studies to clarify this ambiguous issue. The batch culture work with …


Water Quality Dynamics Of Low-Gradient, Headwater Streams In A Timber-Industry Dominated Watershed In Louisiana, Abram Atys Dasilva Jan 2012

Water Quality Dynamics Of Low-Gradient, Headwater Streams In A Timber-Industry Dominated Watershed In Louisiana, Abram Atys Dasilva

LSU Master's Theses

Timber harvesting can degrade the quality of adjacent water bodies, an important concern for Louisiana, nearly 50% of which is forested, and in which the forest industry is the second-largest manufacturing employer. To protect valuable freshwater resources in Louisiana, a manual of best management practices (BMPs) was published in 2000 describing techniques for limiting forestry-caused water quality degradation. While these BMPs are widely implemented, their effectiveness in protecting water quality is largely unknown. To determine the effectiveness of these BMPs, this thesis research conducted three studies to address timber harvest BMP effectiveness on protection of stream dissolved oxygen, metabolism, and …


Thermal And Pore Pressure History Of The Haynesville Shale In North Louisiana: A Numerical Study Of Hydrocarbon Generation, Overpressure, And Natural Hydraulic Fractures, William C. Torsch Jan 2012

Thermal And Pore Pressure History Of The Haynesville Shale In North Louisiana: A Numerical Study Of Hydrocarbon Generation, Overpressure, And Natural Hydraulic Fractures, William C. Torsch

LSU Master's Theses

New drilling technology has led to a revival of drilling in mature petroleum basins such as the Haynesville Formation in east Texas and north Louisiana. In north Louisiana, the Upper Jurassic (Kimmeridgian) aged Haynesville shale has a basinward SW dip and is located at depths ranging from around 10,500 ft to the northeast and 14,000 ft to the southwest with local minimums at the Sabine and Monroe Uplifts. Formation thickness ranges from 100 to 400 feet. Prolific natural gas production is attributed to relatively high average porosity (8 to 14%) and a high geopressure gradient > 0.9 psi/ft. (Wang and Hammes, …


Pretesting In Science: Effect On Unit Test Scores, Mary Catherine Johnson Jan 2012

Pretesting In Science: Effect On Unit Test Scores, Mary Catherine Johnson

LSU Master's Theses

ABSTRACT This study examines the effect that pretesting has on unit test scores in a high school Biology I classroom. The experimental classes were given a pretest before four units of curriculum and then taught the concepts of these units with a traditional lecture based methodology. Their unit test scores were compared to a control class that did not take pretests before the units. In addition, the End of Course (EOC) test scores of the control and experimental classes were compared to determine if pretesting improved transfer of knowledge to a different type of test. Pretesting did not cause a …


An Extensible And Scalable Pilot-Mapreduce Framework For Data Intensive Applications On Distributed Cyberinfrastructure, Pradeep Kumar Mantha Jan 2012

An Extensible And Scalable Pilot-Mapreduce Framework For Data Intensive Applications On Distributed Cyberinfrastructure, Pradeep Kumar Mantha

LSU Master's Theses

The volume and complexity of data that must be analyzed in scientific applications is increasing exponentially. Often, this data is distributed; thus, the ability to analyze data by localizing it will yield limited returns. Therefore, an efficient processing of large distributed datasets is required, whilst ideally not introducing fundamentally new programming models or methods. For example, extending MapReduce - a proven effective programming model for processing large datasets, to work more effectively on distributed data and on different infrastructure (such as non-Hadoop, general-purpose clusters) is desirable. We posit that this can be achieved with an effective and efficient runtime environment …


Influences On Behavior Adaptations To Reduce Exposure To Environmental Hazards Among Residents Of Louisiana's Upper Industrial Corridor, Corrinthia Marie Hinton Jan 2012

Influences On Behavior Adaptations To Reduce Exposure To Environmental Hazards Among Residents Of Louisiana's Upper Industrial Corridor, Corrinthia Marie Hinton

LSU Master's Theses

Over the past century, the growth in petrochemical manufacturing within Louisiana’s Upper Industrial Corridor brought economic development, but also introduced toxic emissions and environmental exposure risks to residents of the area. For the citizens living in close proximity to multiple facilities there is the added risk of chemical exposure from environmentally hazardous accidents. This study seeks to gain insights into patterns of risk-reducing behaviors of residents in East Baton Rouge Parish so that better educational outreach programs can be developed. This research addresses the following questions: To what extent are residents of Baton Rouge taking steps to reduce environmental exposure …


Graham's Variety And Perverse Sheaves On The Nilpotent Cone, Amber Russell Jan 2012

Graham's Variety And Perverse Sheaves On The Nilpotent Cone, Amber Russell

LSU Doctoral Dissertations

In recent work, Graham has defined a variety which maps to the nilpotent cone, and which shares many properties with the Springer resolution. However, Graham's map is not an isomorphism over the principal orbit, and for type A in particular, its fibers have a nice relationship with the fundamental groups of the nilpotent orbits. The goal of this dissertation is to determine which simple perverse sheaves appear when the Decomposition Theorem for perverse sheaves is applied in Graham's setting for type A, and to begin to answer this question in the other types as well. In Chapter 1, we give …


Object Protocols As A Tool For Debugging Method Call Sequencing Constraints, Ronald William Gilkey Jan 2012

Object Protocols As A Tool For Debugging Method Call Sequencing Constraints, Ronald William Gilkey

LSU Master's Theses

Clearly conveying and enforcing the proper ordering of method calls on objects has become a common problem among developers and interface designers. Without the ability of the compilation environment to enforce these constraints, programmers must rely on clear documentation being provided and diligence in programming to ensure that a proper sequence of operations is performed. Commonly, though, type-checking becomes the only tool to help support the correctness of operation sequences as API documentation rarely describes inter-object communications. Thus, the likeliness of producing erroneous and buggy software increases. Object protocols provide a simple and straight-forward approach to solving this problem. They …


Comprehensive Planning And Resilience: A Study Of Louisiana Parishes After Hurricane Katrina, Mary Paille Jan 2012

Comprehensive Planning And Resilience: A Study Of Louisiana Parishes After Hurricane Katrina, Mary Paille

LSU Master's Theses

When hurricanes Katrina and Rita hit in 2005, widespread devastation was felt in over half of the parishes in the state. More than 200,000 homes were damaged and more than 1500 people lost their lives. During this transitionary period, communities were vulnerable and looked for rebuilding leadership. As part of a post-catastrophe resilience movement, the Louisiana Recovery Authority formulated a 50-year regional plan for recovering south Louisiana called Louisiana Speaks. This planning process opened up an opportunity to reach those communities that otherwise may not have considered planning or how it could help them prepare for future events. This places …


Design And Analysis Of Cloaked Fluorophores For Rapid Detection And Visualization Of Cancer Cells Containing Nad(P)H:Quinone Oxidoreductase-1, William Silvers Jan 2012

Design And Analysis Of Cloaked Fluorophores For Rapid Detection And Visualization Of Cancer Cells Containing Nad(P)H:Quinone Oxidoreductase-1, William Silvers

LSU Doctoral Dissertations

The development of fluorogenic substrates for real-time tumor cell detection has led to a vastly expanding field for personal oncology. Fluorophores have been studied as appendages to larger scaffolds leading to accumulation of these dyes in tumor cells or their surrounding environment, taking advantage of tumor anatomy. A new class of fluorophores has been developed in which the dye is an active participant in the mechanism of cancer cell detection. These dyes have been conjugated such that their fluorescence has been eliminated or altered and will undergo a change to reveal their fluorescent signal upon activation by a mechanism that …


Sources Of Salinization Of The Baton Rouge Aquifer System: Southeastern Louisiana, Callie Elizabeth Anderson Jan 2012

Sources Of Salinization Of The Baton Rouge Aquifer System: Southeastern Louisiana, Callie Elizabeth Anderson

LSU Master's Theses

A major environmental and economic problem confronting the Baton Rouge area, southeastern Louisiana, is the progressive salinization of the Baton Rouge aquifer system, an important source of fresh municipal and industrial groundwater. The Baton Rouge fault marks a boundary between fresh groundwaters to the north and predominately brackish waters to the south. Determining the permeability architecture of the fault is an essential component of modeling groundwater flow and saline contamination north of the fault. Understanding the sources and pathways of the saline waters that are migrating into the freshwater sands north of the fault is thus essential in helping to …


The Effect Of Extrinsic Rewards In The High School Classroom, Amanda Vargo Jan 2012

The Effect Of Extrinsic Rewards In The High School Classroom, Amanda Vargo

LSU Master's Theses

One of the biggest obstacles that a high school teacher faces in the classroom is motivating students to complete work. Traditional ideology focuses on intrinsic rewards as way to encourage students to participate and try in the classroom. Things like valuing education, planning for college, and taking pride in a good report card are used in attempts to motivate. Yet, in the adult world, people expect a concrete extrinsic reward (i.e. a paycheck) for the work that they do. This study takes the idea of extrinsic rewards and brings them into the classroom. This study was conducted over two academic …

Modeling Gopher Tortoise (Gopherus Polyphemus) Habitat In A Fire-Dependnent Ecosystem In North Florida, Christina Legleu Jan 2012

Modeling Gopher Tortoise (Gopherus Polyphemus) Habitat In A Fire-Dependnent Ecosystem In North Florida, Christina Legleu

LSU Master's Theses

Gopher tortoise (Gopherus polyphemus) populations have declined with longleaf pine (Pinus palustris) ecosystems across their historic range. The influence of gopher tortoise burrows on co-inhabiting plants and animals necessitates an understanding of how landscape features and management practices influence gopher tortoise presence, absence, and abandonment. In this study, naïve gopher tortoise burrow encounter rates from a line transect distance sampling (LTDS) pilot study were used for two methods of modeling gopher tortoise habitat. In Chapter 1, naïve encounter rates were tested for a linear correlation to a HSI model created from three ranked geographic information system (GIS) landscape variables. Initial …


Identification And Incorporation Of Quantitative Indicators Of Ecosystem Function Into Single-Species Fishery Stock Assessment Models And The Associated Biological Reference Points, Melissa Hedges Monk Jan 2012

Identification And Incorporation Of Quantitative Indicators Of Ecosystem Function Into Single-Species Fishery Stock Assessment Models And The Associated Biological Reference Points, Melissa Hedges Monk

LSU Doctoral Dissertations

The move towards an ecosystem approach to fisheries management requires baseline information on the biotic communities and an understanding of the interactions among species. The two objectives of this study were to describe the demersal fish community (DFC) associated with the northwestern Gulf shrimp trawl fishery, and to utilize a multispecies Lotka-Volterra model to examine possible community level effects of fishing. Community level effects include predator-prey interactions and the responses of fish in the same community to fishing pressure. The summer and fall Southeast Area Monitoring and Assessment Program (SEAMAP) bottomfish trawl surveys were used to identify spatial and temporal …

Sediment Flux & Fate For A Large-Scale Diversion: The 2011 Mississippi River Flood, The Bonnet Carré Spillway, And The Implications For Coastal Restoration In South Louisiana, Jeffrey Bryant Fabre Jan 2012

Sediment Flux & Fate For A Large-Scale Diversion: The 2011 Mississippi River Flood, The Bonnet Carré Spillway, And The Implications For Coastal Restoration In South Louisiana, Jeffrey Bryant Fabre

LSU Master's Theses

Dams and hardened levees built by European settlers in the last two centuries have degraded or stopped the cyclic sedimentation patterns that built the Mississippi River Delta Plain over the past 7,000-8,000 years. Man-made diversions of sediment-laden river water along the lower Mississippi, operated during high water periods, are being considered as a primary mechanism for combating the land loss induced by rising sea-level and these modern controls. To date, no study has documented the sediment-delivery potential of a large man-made river diversion during a single high water event. In the spring of 2011, historic flooding on the Mississippi River …
