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 …

Measurement Of Nutrient Availability In Feedstuffs For Florida Pompano And Development Of Formulated Diets For Pompano Aquaculture, Craig Gothreaux

LSU Master's Theses

Consistently high market demand combined with low commercial catches have made Florida pompano, Trachinotus carolinus, one of the highest valued finfish from the Gulf of Mexico. Economic incentive has spurred interest in pompano culture since the 1950s, yet the body of nutritional research on pompano is still sparse. This study was conducted to measure the apparent digestibility of nutrients among a selection of common feed ingredients, and determine the optimum dietary protein level for juvenile Florida pompano at a fixed protein-to-energy ratio, in order to formulate nutritionally complete, cost-effective diets. The four ingredients tested in the digestibility trial were soybean …

The Effects Of In Utero Environmental Tobacco Smoke Exposure On Immune Responses To Allergen In Adult Offspring, Rodney Lamar Rouse Jan 2008

The Effects Of In Utero Environmental Tobacco Smoke Exposure On Immune Responses To Allergen In Adult Offspring, Rodney Lamar Rouse

LSU Doctoral Dissertations

Fetal stress has been linked to adult atherosclerosis, obesity, and diabetes. Epidemiology studies have associated fetal exposure to maternal smoking and post-natal exposure to environmental tobacco smoke (ETS) with increased asthma risk. We tested the hypothesis, in a mouse model of asthma, that ETS exposure in utero alters airway function and respiratory immune responses in adult offspring. Pregnant BALB/c mice were exposed daily to ETS or filtered air (AIR). Neonatal gene expression was assessed. Offspring inhaled aerosolized ovalbumin (OVA) or saline in weeks 7-8. Regardless of whether they inhaled OVA or saline, mice were sensitized by OVA injections in weeks …

Resistant Starch Is Effective In Lowering Body Fat In A Rat Model Of Human Endocrine Obesity, Julina Ann Robert Jan 2008

Resistant Starch Is Effective In Lowering Body Fat In A Rat Model Of Human Endocrine Obesity, Julina Ann Robert

LSU Master's Theses

Two studies were performed to determine the effects of resistant starch (RS) on body weight and fat. A 2x2 factorial design was used in both studies, and results were considered significant when p<0.05 for both studies. The first study examined the effects of RS in a high fat diet (44.8% of energy) on weight, fat, peptide-YY (PYY) levels, and cecal pH in male Sprague-Dawley rats. Rats were fed a low fat energy control diet for one week prior to diet treatment. On week two, rats were blocked by weight and fed one of the following diets for 12 weeks (n=10): low fat, energy control (LFEC); LF resistant starch (LFRS); high fat, energy control (HFEC); or high fat resistant starch (HFRS). RS did not lower weight or fat with either the HF or LF diets. RS consumption resulted in greater full and empty cecal weights, and a lower pH for the LFRS diet. This data indicate fermentation, even though weight and fat loss did not occur. This is contrary to previous reports with RS, which has been shown to decrease body fat compared to controls. The second study examined the effects of RS on the weight, fat, PYY levels, and glucagon-like peptide-1 (GLP-1) levels in female Sprague-Dawley rats. Ovariectomized (OVX) rats were used to represent rats prone to gaining weight, and sham rats represented normal rats. Rats were assigned to one of four groups (n=10): OVEC, OVRS, SHEC, or SHRS. Rats were fed the EC diet for 6 weeks prior to diet treatment to gain weight after surgery, and then blocked by weight and fat into diet treatment groups, and spent 13 weeks on treatment diets. Energy intake, total gastrointestinal weight, large intestine/cecum weight, and small intestine weight were all higher in RS fed rats relative to EC fed rats. Mesenteric, ovarian, perirenal, retroperitoneal, and total fat pads were lower in RS rats relative to EC rats. Although RS was not effective in lowering body weight or body fat in the first study, the data indicates that resistant starch may lower body weight and fat in postmenopausal women.

A Longitudinal Study Of Married Women's Probability Of Being Housewives In Reforming Urban China, Chiung-Yin Hu Jan 2008

A Longitudinal Study Of Married Women's Probability Of Being Housewives In Reforming Urban China, Chiung-Yin Hu

LSU Doctoral Dissertations

This study examines married women’s employment status and the factors associated with their being full-time housewives between 1989 and 2004 in urban China. I argue that the transition from a command economy to a market-oriented economy since the early 1980s has had negative impacts on married women’s labor force participation. Using six waves of the Chinese Health and Nutrition Survey (1989, 1991, 1993, 1997, 2000, and 2004), I find that the percentages of full-time housewives in urban China tripled in just 15 years, and the largest amount of growth occurred in the most recent period. Regression analyses confirm that married …

An Analysis Of Marine Protected Areas Legislation In The Caribbean Lesser Antilles, Barry James Bleichner Jan 2008

An Analysis Of Marine Protected Areas Legislation In The Caribbean Lesser Antilles, Barry James Bleichner

LSU Master's Theses

Historically, marine resources and ecosystems were believed to be limitless and exploitation of those resources occurred with little regard to future consequences. Recent studies suggests that this belief is misplaced, as research indicates that many of these marine resources face extinction if protective measures are not implemented soon. Marine protected areas, or MPAs have garnered increasing attention as a means to effectively protect and conserve marine resources. Establishment and management of marine protected areas typically require implementing legislation in order to provide a legal basis for enforcement of MPA rules and regulations. The intent of this research was to determine …

Heterogeneous Catalyzed Macromolecular Hydrogenations In Oscillating Systems, Alan Bussard Jan 2008

Heterogeneous Catalyzed Macromolecular Hydrogenations In Oscillating Systems, Alan Bussard

LSU Doctoral Dissertations

An examination of novel oscillatory (alternating gas and liquid phase) reactors and heterogeneous catalysts for multi-phase macromolecular reactions was carried out. A monolith-containing square die with Pd/Al2O3 catalysts was used to successfully hydrogenate poly(styrene) (PS). The inherent pulse behavior of the extruder was found to be sufficient to approach intrinsic kinetics at low polymer concentrations. At higher (10 wt% PS) concentrations, forced pulsing was shown to have a greater impact on observed reaction rates. Selectivity with this extruder-fed reactor was better than with a stirred tank in all cases, due to a more plug-flow-like residence time distribution. While accurate control …
