Effects Of Winter Burning And Structural Marsh Management On Bird And Plant Communities Of The Gulf Coast Chenier Plain., Steven Walter Gabrey Jan 1999

Effects Of Winter Burning And Structural Marsh Management On Bird And Plant Communities Of The Gulf Coast Chenier Plain., Steven Walter Gabrey

LSU Historical Dissertations and Theses

Many Gulf Coast Chenier Plain marshes are managed through a combination of winter burning and structural marsh management (SMM) to improve habitats for waterfowl and furbearers and reduce wetland loss. These practices are controversial because of concerns regarding ability to achieve goals coupled with potential negative effects on other marsh processes or organisms. I investigated the effects of winter burning and SMM on bird and plant communities of Chenier Plain marshes in southwest Louisiana. I recorded bird and plant species abundance and vegetation structure in experimental burned and unburned marshes over two winters and three breeding seasons. Vegetation structure (visual …

Holding Back The Waters: Land Development And The Origins Of Levees On The Mississippi, 1720-1845., Jeffrey Alan Owens Jan 1999

Holding Back The Waters: Land Development And The Origins Of Levees On The Mississippi, 1720-1845., Jeffrey Alan Owens

LSU Historical Dissertations and Theses

Man's efforts to control flooding on the Mississippi began about 280 years ago, but the first 130 years has been neglected in scholarly literature. In spite of abundant primary sources, most histories of flood control on the Mississippi revolve around hydraulic engineering and the contributions of state and federal levee bureaucracies---factors which had almost no impact on the creation of the levee system. Engineers did install the first levee at New Orleans and levees on their own plantations in the 1720s, but the extension of the levee line thereafter was almost entirely the work of private land developers supervised at …

Studies On Cyclooxygenase-2 Expression In Lipopolysaccharide-Stimulated Macrophages., Byeong Churl Jang Jan 1999

Studies On Cyclooxygenase-2 Expression In Lipopolysaccharide-Stimulated Macrophages., Byeong Churl Jang

LSU Historical Dissertations and Theses

Cyclooxygenase (COX) is the key enzyme in the biosynthesis of prostaglandins (PGs) known as pro-inflammatory mediators. COX has two isoforms: the constitutively expressed COX-1 and the mitogen-inducible COX-2. It has been demonstrated that COX-2 expression is selectively induced by lipopolysaccharide (LPS) treatment after several hours in rat alveolar macrophages (Lee et al., 1992; Chanmugam et al., 1995). The mitogen-activated protein kinases [MAPKs; extracellular signal-regulated kinases (ERKs), P38, and c-jun N-terminal kinases (JNKs)], nuclear factor kappa B (NF-kB), and Lyn kinase are known to be activated in the early stages (within minutes) of LPS signaling pathways. In the current study, the …

The Historical And Cultural Geography Of The Grange In Minnesota And Louisiana, 1870-1880., Linda Marie Thorstad Jan 1999

The Historical And Cultural Geography Of The Grange In Minnesota And Louisiana, 1870-1880., Linda Marie Thorstad

LSU Historical Dissertations and Theses

This study uses historical and geographical inquiry to examine postbellum agrarian social, political and economic unrest that in 1868 led to the formation of the first national, secret and ritualistic, fraternal agricultural society known as the Grange. The Grange was created to unite farmers through cooperative buying and selling, to promote agricultural education, and to create a social organization that encouraged both women and men to acquire and refine leadership skills. It also sought to address concerns over monopolies and promoted state regulation of railroad rates. Although Grange membership peaked in 1875 and sharply declined through 1880, it forged the …

In Vivo And In Vitro Stimulation Of Murine Splenocytes With Brevetoxin-2 Immunogenic Conjugates For The Preparation Of Monoclonal Antibodies Against Ciguatoxin-Related Compounds., Sonia Edith Guzman Perez Jan 1999

In Vivo And In Vitro Stimulation Of Murine Splenocytes With Brevetoxin-2 Immunogenic Conjugates For The Preparation Of Monoclonal Antibodies Against Ciguatoxin-Related Compounds., Sonia Edith Guzman Perez

LSU Historical Dissertations and Theses

The proliferation of toxic algae is a natural phenomenon known as a harmful algal bloom. Ciguatera fish poisoning and neurotoxic fish poisoning are syndromes associated with this phenomenon. Current methods for the detection of their toxins (ciguatoxins and brevetoxins) are expensive, time-consuming, require trained personnel and special laboratory equipment. In the case of ciguatoxins, the lack of standard material worsens the problem. Specific objectives of this study included the use of brevetoxin-2 (PbTx-2) for the preparation of antibodies which could cross-react with ciguatoxins, the use of different PbTx-2 immunogenic conjugates, the use of in vivo versus in vitro stimulation of …

Production Of L-(+) Lactic Acid From Blackstrap Molasses By Lactobacillus Casei Subspecies Rhamnosus Atcc 11443., Narumol Thongwai

LSU Historical Dissertations and Theses

Lactobacillus casei subspecies rhamnosus grew on non-supplemented blackstrap molasses. The bacteria grew best at the optimal temperature of 40 +/- 2°C, and at pH 5.5. Addition of yeast extract to molasses shortened the lag phase and increased cell mass. In batch fermentations without pH control, the highest ratio of lactic acid produced to cell mass was 12 from non-supplemented molasses. For pH controlled batch fermentations, the ratio's of lactic acid produced/cell mass were 81, 79, 51 and 31 for 0, 0.2, 0.4 and 0.8% yeast extract supplementation, respectively. Non-supplemented molasses, 8% Brix, produced 28 +/- 2 g/l of lactic acid …

Development Of Immunochemical Methods For Gossypol Analysis., Xi Wang Jan 1999

Development Of Immunochemical Methods For Gossypol Analysis., Xi Wang

LSU Historical Dissertations and Theses

Gossypol is a reactive polyphenolic compound present in the cotton plant. During cottonseed processing, gossypol can react with other compounds to form bound gossypol. Gossypol analyses using chemical methods do not always agree with its bioavailability to animal possibly because of various bound forms of gossypol with different stabilities in vivo and the (+/-)-gossypol enantiomers with different biological activities. The objectives of this research were to produce anti-gossypol antibodies and use antibodies to study gossypol chemistry and to analyze gossypol in cottonseed samples and cottonseed by-products. Polyclonal antibodies were produced from rabbits after they were immunized with gossypol-LPH (Limulus polyphemus …

Isolation Of Antimutagenic Compounds In Corn And Cottonseed., Henry Njapau Jan 1999

Isolation Of Antimutagenic Compounds In Corn And Cottonseed., Henry Njapau

LSU Historical Dissertations and Theses

Food, which ensures the sustenance of life, has also been implicated in the development or prevention of numerous diseases including cancer. Cancer may be a result of hereditary factors or genomic instability induced by DNA damage, from the intrinsic chemistry of cells or extrinsic factors like aflatoxin B1. Aflatoxin B1, produced by Aspergillus flavus and Aspergillus parasiticus, is a common contaminant of corn and cottonseed and a proven mutagen and animal carcinogen. Increased scientific knowledge and establishment of regulation have reduced but not eliminated exposure to aflatoxin B1. Complete elimination may be uneconomical for producers and may deprive consumers of …

Experimental Mammalian Predator Removal And Other Factors Affecting Dabbling Duck Reproduction In North Dakota., Pamela Renee Garrettson Jan 1999

Experimental Mammalian Predator Removal And Other Factors Affecting Dabbling Duck Reproduction In North Dakota., Pamela Renee Garrettson

LSU Historical Dissertations and Theses

In the prairie pothole region, high predation rates often reduce duck nest success below the 15--20% thought necessary for population stability. Lethal removal of mammalian predators of duck nests is one potential management option, but there is little reliable information about the effects on nest success of removing mammalian predators without using poisons. On 16 4,150-ha blocks, half of them trapped during spring and summer, I found higher ( P < 0.001) nest success on trapped sites (45%) than on untrapped sites (17%). There were no year (P = 0.296), year-treatment (P = 0.423), or species-treatment (P > 0.895) effects. Nest success of blue-winged teal (Anas discors) and gadwalls (A. strepera) was higher than that of mallards ( A. platyrhynchos) and pintails (A. acuta, P = 0.028) on …

The Evolution Of The Red River Valley Settlement System, 1714--1860., Keumsoo Hong Jan 1999

The Evolution Of The Red River Valley Settlement System, 1714--1860., Keumsoo Hong

LSU Historical Dissertations and Theses

Since the first European settlement was established in the middle of Indian territory in 1714, the Red River Valley had experienced a dramatic transformation until the end of the antebellum period. The trajectory of the evolution can be divided into five vertical cross sections. The formative phase (1714--1803) features the colonial regimes in political arena, less-specialized regional economies, nascent urban units laden heavily with defensive functions, and coerced labor system. The settlement system resembled a semi-primate pattern with Natchitoches on the summit. The period of the Territory of Orleans (1804--1812) corresponded to the transition phase. During this interim, traditional staples …
