Spatial And Temporal Dynamics Of Stream Water Chemistry In A Headwater Catchment Of Central Louisiana, April Bryantmason
LSU Master's Theses
One of the dominant themes of stream water quality research has been the effect of nutrients and organic materials on eutrophication of coastal waters. Despite this prevalence in water quality research, few studies have been conducted on water quality changes in low-gradient watersheds under a humid, warm subtropical climate, such as those in the coastal plains of the Northern Gulf of Mexico. This study addresses: (1) the nutrient conditions in headwater streams of a low-gradient, subtropical watershed, especially as it relates to the suggested criteria by the Environtmental Protection Agency (EPA), (2) organic and inorganic carbon dynamics in the headwaters …

Comprehensive Planning In Louisiana, Lynn A. Maloney-Mújica
LSU Master's Theses
This study explores the factors associated with the implementation of land use planning policies and tools among the parishes (counties) of Louisiana. There is an absence of statutory standards, strict guidelines, and other external drivers for planning in Louisiana and the extent to which local governments regulate land use varies widely among local jurisdictions. The purpose of this study is to provide an empirical model of intrinsic factors that might explain why some parishes have decided to intervene in land use by adopting a high number of planning policies and tools, and why others have failed to adopt few, if …

An Evaluation Of The Perceived Obstacles For Policy Officials Regulating The Post Harvest Treatment Of Raw Oysters To Control The Human Health Vibrio Vulnificus Problem, Amy Leah Oestringer
LSU Master's Theses
Vibrio vulnificus is the leading pathogen linked to seafood-associated deaths. This naturally occurring marine bacterium presents a human health risk when it is consumed in raw oysters. Hospitalization is necessary in 90 % Vibrio vulnificus illnesses and 40% end in death. (CDC) Several guidelines and regulations have been enacted to combat this human health issue, but have failed to reduce the steadily rising illness rate. Post-harvest processing requirements for raw oysters could be used to reduce illness rates. A survey was conducted to measure the perceived obstacles that regulators and industry representatives of the raw oyster industry face in policymaking …

Effects Of Burning On Henslow's Sparrow (Ammodramus Henslowii) Density And Habitat Quality In Louisiana, Laura M. Palasz
LSU Master's Theses
The Henslow’s Sparrow (Ammodramus henslowii) is a grassland species of concern that winters in prairies and open pine savannas across the Gulf Coastal Plain. Previous studies have indicated that these birds occur at higher densities in recently burned habitats in winter, but this has never been examined over a large geographic area containing multiple habitat types. The objectives of the study were to identify areas of important winter habitat in Louisiana, to examine the relationship between time since burn, bird density, and bird condition, and to determine vegetation structure and composition used by birds. We found most of the new …
Non-Industrial Private Forest Landowners And Us Home Center Retailers' Attitudes And Perceptions Of Forest Certification, Polwattage Kushil Perera
Non-Industrial Private Forest Landowners And Us Home Center Retailers' Attitudes And Perceptions Of Forest Certification, Polwattage Kushil Perera
LSU Master's Theses
The concept of forest certification, a relatively recent development in forestry, is based on the use of market-based incentives to encourage sustainable forest management practices. Since the majority of forests in US South are privately owned, certifying forests owned by non-industrial private forest (NIPF) landowners is an important issue. From the demand perspective of certification, pressure from non-governmental environmental organizations and consumer awareness has prompted major wood products retailers to state preferences for certified wood products. In the US, wood product demand in the retail home centers sector is second only to the home building industry. In addition, home center …

Land Use And Water Quality Characterization Of Boeuf Basin, La, Joseph Wesley Leblanc
LSU Master's Theses
The three primary goals of this project were to establish the ambient background of water quality in the Lake Boeuf basin in southeast Louisiana; establish land use patterns in the basin and the relation to water quality; and develop a preliminary plan to improve water quality through the use of best management practices and wetland assimilation. Urban and agricultural acreage borders the basin and runoff from these lands forces loadings of nutrients into the adjacent canals where they become channelized and ultimately exit the Boeuf Basin into Lac des Allemandes. From September 2007 until February 2008, water sampling occurred monthly …
Strategic Analysis Of Ghana's Wood Export Sector, Odoom Domson
Strategic Analysis Of Ghana's Wood Export Sector, Odoom Domson
LSU Master's Theses
Export-led strategies are very crucial to achieving growth and goals of developing and transition economies such as Ghana. As a result, export strategies are being adopted in many developing countries. Although such export strategies might be in place, the deployment of resources and tax payers’ money involved often calls for the investigation of programs and initiatives that exist and perceptions by industry if they are working. Furthermore, Ghana wood exports to the US, a historically major market, have been declining over the past six years. Therefore, there is the need to determine if export constraints to the US market exist. …

Two Post-Harvest Treatments For The Reduction Of Vibrio Vulnificus And Vibrio Parahaemolyticus In Eastern Oysters (Crassostrea Virginica), Kevin Patrick Melody
LSU Master's Theses
Vibrio vulnificus and V. parahaemolyticus are naturally occurring estuarine bacteria and the leading causes of seafood-borne illness in the United States. Multiple outbreaks due to raw oyster consumption in the last decade has lead to much research to remediate these bacteria from oysters destined for the half-shell market. The focus of this research was to investigate the efficacy of icing and high salinity exposure as two post-harvest treatments for the reduction in numbers of V. vulnificus and V. parahaemolyticus in commercial quantities of shellstock oysters. The icing experiment was conducted in the summer of 2006, and the high salinity trials …

Pileated Woodpeckers (Dryocopus Pileatus) And Saproxylic Beetles In Partial Cut And Uncut Bottomland Hardwood Forests, Patricia Jean Newell
LSU Master's Theses
Relative abundance and species richness of saproxylic beetles and nesting, roosting, and foraging ecology of pileated woodpeckers were studied in recent partial cuts and uncut forest during the summers of 2006 and 2007. Relative abundance of saproxylic beetles was greater in one-year old cuts than uncut forest during 2006 but was not consistent during 2007. The number of dead trees, period of capture, and trapping year also influenced beetle abundance. Species richness was similar in partial cuts and uncut forest. Characteristics of habitat used by pileated woodpeckers for nesting and roosting in one-year-old and two-year-old partial cuts and uncut forest …

Biotransformation Of Organic Wood Preservatives By Micro-Organisms, Diana Nasirumbi Obanda
LSU Doctoral Dissertations
Wood products are treated with biocides to prevent biodegradation by bacteria, fungi, and insects. Much attention is being directed towards testing of metal-free organic preservative systems. The major disadvantage of organics is that they are biotransformed by micro-organisms in soil and wood. This study explored the biotransformation of the fungicide tebuconazole by a bacteria species (Pseudomonas fluorescens), the mold (Trichoderma harzianum), the white rot fungus (Phanerochaete chrysosporium) and the brown rot (Meruliporia incrassata). After incubation of cultures spiked with tebuconazole, samples were analyzed for chemical remaining and metabolites. M. incrassata, T. harzianum, and the bacterium all cleaved the 1, 2, …
Rice Straw Fiber Polymer Composites: Thermal And Mechanical Performance, Fei Yao
Rice Straw Fiber Polymer Composites: Thermal And Mechanical Performance, Fei Yao
LSU Doctoral Dissertations
Rice straw fiber can be considered as important potential reinforcing filler for thermoplastic composite because of its lignocellulosic characteristics. It is thus of practical significance to understand and predict the thermal decomposition process of rice straw fibers. A method proposed by Málek, Šesták, and co-workers was used to investigate and model thermal decomposition process of common natural fibers with detailed analysis on rice straw system. Assuming a global model occurring within the entire degradation of natural fibers with consideration of fiber as one pseudo-component, model can be used to describe both isothermal and non-isothermal degradation process of most selected fibers …
Identification Of Quantitative Trait Loci Influencing Early Height Growth In Longleaf Pine (Pinus Palustris Mill), Lisha Wu
LSU Doctoral Dissertations
The delay in early height growth (EHG) has been a limiting factor for artificial regeneration of longleaf pine (Pinus palustris Mill.). Simple Sequence Repeat (SSR) markers have been used to map the genome and quantitative trait loci controlling the EHG in a backcross family (longleaf pine x slash pine) x longleaf pine. A total of 228 locus specific SSR markers were screened against 6 longleaf pine recurrent parents and a sample of 7 longlef x slash pine hybrid parents. In total, 135 polymorphic markers were identified. Based on the genetic variance in EHG, available sample size, and the number of …
