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 …

Interactions On Minerals And Organic Materials Along The Salinity Gradient In Barataria Basin, Louisiana., Jessica Anne Kastler Jan 1999

Interactions On Minerals And Organic Materials Along The Salinity Gradient In Barataria Basin, Louisiana., Jessica Anne Kastler

LSU Historical Dissertations and Theses

Changes in the associations among mineral and organic materials in estuaries may control the nature and quantity of organic material (OM) preserved in sediment deposits or cycled in the water column. Estuarine sediment-OM attachments were examined using descriptive analyses and experiments to assess their response to salinity changes and the bioavailability of sedimentary OM. Desorption experiments compared the amount of organic carbon extracted from sediment in rinses of different salinity. Uptake experiments monitored changes in carbon and bacteria concentrations to compare the bioavailability of dissolved and sedimentary OM. Clay mineralogy, surface area and elemental analysis of suspended and deposited sediment …

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 …

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 …

Fluctuating Silicate : Nitrate Ratios And Coastal Plankton Food Webs, N Qureshi, N N. Rabalais, Q Dortch, R. Eugene Turner, R F. Shaw, J Cope Jan 1998

Fluctuating Silicate : Nitrate Ratios And Coastal Plankton Food Webs, N Qureshi, N N. Rabalais, Q Dortch, R. Eugene Turner, R F. Shaw, J Cope

Faculty Publications

Marine diatoms require dissolved silicate to form an external shell. and their growth becomes Si-limited when the atomic ratio of silicate to dissolved inorganic nitrogen (SI:DIN) approaches 1:1, also known as the Redfield ratio. Fundamental changes in the diatom-to-zooplankton-to-higher trophic level food web should occur when this ratio falls below 1:1. and the proportion of diatoms in the phytoplankton community is reduced. We quantitatively substantiate these predictions by using a variety of data from the Mississippi River continental shelf, a system in which the SI:DIN loading ratio has declined from around 3:1 to 1:1 during this century because of land-use …

Measurement And Inheritance Of Resistance To Sheath Blight Caused By Rhizoctonia Solani Kuhn In Rice., Xueyan Sha

LSU Historical Dissertations and Theses

Sheath blight (ShB), caused by Rhizoctonia solani Kuhn, has been the most destructive rice disease in Louisiana. To breed ShB resistant varieties, an effective procedure for screening progenies of segregating populations is required and detailed knowledge of the mode-of-inheritance of partial ShB resistance is also necessary. In this study four inoculation methods; rice hull/grain mixture (MIX), rice straw, toothpick, and brown rice, along with five assessment systems; 0-9 rating scale (RAT9), relative lesion height (RLH), disease severity (DS), disease incidence, and lesion height were compared on nine rice genotypes showing different resistance levels to ShB. Progenies of segregating populations from …

Crystal Structure Of Apo-Glycine N-Methyltransferase (Gnmt), R. Pattanayek, M. E. Newcomer, C. Wagner

Faculty Publications

The crystal structure of the recombinant apo-form of glycine N- methyltransferase (GNMT) has been determined at 2.5 Å resolution. GNMT is a tetrameric enzyme (monomer M(r) = 32,423D(a), 292 amino acids) that catalyzes the transfer of a methyl group from S-adenosylmethionine (AdoMet) to glycine with the formation of S-adenosylhomocysteine (AdoHcy) and sarcosine (N- methylglycine). GNMT is a regulatory enzyme, which is inhibited by 5- methyltetrahydrofolate pentaglutamate and believed to control the ratio of AdoMet to AdoHcy in tissues. The crystals belong to the orthorhombic space group P21212 (a = 85.39, b = 174.21, c = 44.71 Å) and contain one …

Performance And Metabolic Responses Of Young Dairy Calves Fed Diets Supplemented With Chromium Tripicolinate, C. L. Depew, L. D. Bunting, J. M. Fernandez, D. L. Thompson, R. W. Adkinson

Faculty Publications

Forty-two Holstein calves were used to study performance and metabolic responses when milk replacer and then postweaning starter were supplemented with 1 ppm of Cr as Cr-tripicolinate. From birth through 8 wk of age, supplemental Cr tended to improve the growth performance of bull calves but not of heifer calves. Starter intake and feed efficiency were not affected by supplemental Cr. From 1 to 5 wk of age, plasma cortisol concentrations sampled just prior to feeding decreased, and concentrations of insulinlike growth factor-I increased. All calves appeared to become less sensitive to insulin as they aged. From 1 to 5 …
