Impacts Of Coastal Acidification On Louisiana Plankton, Amy Mallozzi Aug 2017

Impacts Of Coastal Acidification On Louisiana Plankton, Amy Mallozzi

LSU Master's Theses

Anthropogenic input of carbon dioxide (CO2) has an increasingly acidifying effect on the world’s oceans with the potential to impact biogeochemical cycles and food web dynamics. Coastal Louisiana is an area highly vulnerable to changing climate, but the unique local water chemistry created by input from the Mississippi and Atchafalaya Rivers makes the manifestation of elevated CO2 and its biological implications difficult to predict. Louisiana estuaries are highly productive and support a large commercial market for the eastern oyster, Crassostrea virginica. This study explores the use of experimental microcosms to expose natural phytoplankton assemblages and larval …

Preferences And Values For The Gulf Coast Ocean Observing System, Cody Lynn Plummer Jan 2017

Preferences And Values For The Gulf Coast Ocean Observing System, Cody Lynn Plummer

LSU Master's Theses

Integrated Ocean Observing Systems (IOOS) provide real time oceanic data and sea state forecasting information that is utilized by numerous public and private sectors engaging in maritime activities. The U.S. Gulf Coast constituent of this system (GCOOS) consists of 321 platforms, buoys, and sensors that provide measurements of wind speed, wave height, water quality, and other parameters. Government entities have proposed an expansion of this infrastructure by 40% at an estimated cost of $35 million for installation and $33 million annually for maintenance. As part of a larger project commissioned to estimate monetized benefits of this expansion, this study applied …


Evaluation Of Biochar As A Feed Additive In Commercial Broiler Diets, Brandon Michael Cheron Jan 2017

Evaluation Of Biochar As A Feed Additive In Commercial Broiler Diets, Brandon Michael Cheron

LSU Master's Theses

Two experiments were conducted to evaluate sugarcane biochar as a feed ingredient in commercial broiler diets. Experiment 1 was conducted for 11 days using 300 male Ross 708 broilers. Broilers were allotted to one of five treatment diets containing 0%, 0.5%, 1.0%, 2%, or 4% biochar. Experiment 2 was conducted for 19 days using 450 male Ross 708 broilers. Chicks were allotted to one of 9 treatment diets containing 0%, 0.25%, 0.5%, 0.75%, 1%, 1.25%, 1.5%, 1.75% or 2% biochar. Broilers and feed were weighed at day 0 and 10 in experiment 1 and day 0, 10 and 18 in …


Design And Humoral Analysis Of Two Epitope-Based Brucella Abortus Dna Vaccines, Michael Mcgee Jan 2017

Design And Humoral Analysis Of Two Epitope-Based Brucella Abortus Dna Vaccines, Michael Mcgee

LSU Master's Theses

Brucella is a genus of Gram negative, facultative intracellular pathogens which cause brucellosis, one of the most wide spread zoonotic diseases. Brucellosis causes a severe economic burden due to reproductive loss in animals and human infection. Vaccination of animals has proven to be the most effective means of controlling brucellosis; however the current live-attenuated vaccines are not considered ideal. The live-attenuated vaccines Brucella abortus Strain 19 and RB51 remain pathogenic to humans, and the former interferes with diagnostic tests due to induction of antibodies against the O-polysaccharide. DNA vaccination with single antigens has proven to be successful at protecting mice …


Biology And Ecology Of Crapemyrtle Bark Scale, Acanthococcus Lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), Zinan Wang Jan 2017

Biology And Ecology Of Crapemyrtle Bark Scale, Acanthococcus Lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), Zinan Wang

LSU Master's Theses

The crapemyrtle bark scale, Acanthococcus lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), is an exotic pest on crapemyrtles, Lagerstroemia spp. (Myrtales: Lythraceae). Because of its recent arrival in the US, little is known about its biology and ecology. The purpose of my thesis was to improve the knowledge about A. lagerstroemiae in four aspects involving its thermal tolerance, physiological adaptations to cold temperatures, temperature-dependent development and host range. Thermal tolerance was determined to understand how temperature extremes constrain the distribution of A. lagerstroemiae in the US. Results suggested that A. lagerstroemiae can tolerant high heat, but its potential distribution to the northern US …


Comparative Viability Of Spray Dried Lactobacilli Affected By Different Protective Agents And Storage Conditions, Vondel Vandeker Reyes Ortega Jan 2017

Comparative Viability Of Spray Dried Lactobacilli Affected By Different Protective Agents And Storage Conditions, Vondel Vandeker Reyes Ortega

LSU Master's Theses

Because of their health benefits, probiotics are a significant part of the functional food industry. Spray drying is reported as the most common method used in the food industry to encapsulate probiotics. The objectives of this study were to investigate the effects of protective agents on the viability of lactobacilli after spray drying and during storage at different conditions and to evaluate spray drying conditions to produce these probiotic powders. Lactobacillus plantarum NRRL B-4496 (LP) and Lactobacillus acidophilus NRRL B-4495 (LA) were separately grown (~109 CFU/ml) and suspended in a 200 g/L solution of high maize starch (HM); maltodextrin (MD); …


Soil Properties' Response To Wheat And Corn Stubble Residue Management In Louisiana, Autumn Danielle Acree Jan 2017

Soil Properties' Response To Wheat And Corn Stubble Residue Management In Louisiana, Autumn Danielle Acree

LSU Master's Theses

Crop residue plays an important role in improving soil fertility. Crop residue affects soil biological and chemical properties by increasing soil organic matter, nutrient status and availability, and microbial activity. The degree of the effects of crop residue on soil fertility depends on the crop residue management practice. Samples were collected in 2014 in wheat (Triticum spp.) stubble and corn (Zea mays) stubble residue. A second soil sample collection under wheat stubble residue was taken in 2015 in the prescribed fire and no-till sections. A total of 342 soil samples (0-2.5cm) were collected across conventional tillage, no-till, and prescribed fire …


Susceptibility Of The Southern House Mosquito, Culex Quinquefasciatus, In East Baton Rouge Parish To Larval Insecticides, Nicholas Alexander Delisi Jan 2017

Susceptibility Of The Southern House Mosquito, Culex Quinquefasciatus, In East Baton Rouge Parish To Larval Insecticides, Nicholas Alexander Delisi

LSU Master's Theses

Mosquito control districts in Louisiana focus their efforts on Culex quinquefasciatus, the primary vector of West Nile virus in the southern United States, with rigorous larvicide treatments. However, the development of resistant populations of Cx. quinquefasciatus in response to extensive insecticide application has been demonstrated repeatedly. Examining changes in insecticide susceptibility and larvicide efficacy in real world scenarios can help inform mosquito control districts as to whether or not their treatments are killing mosquitoes. We hypothesized that frequent larvicide applications for the control of mosquitoes in East Baton Rouge Parish had lowered susceptibility of wild Cx. quinquefasciatus to insecticides, and …


The Effect Of Storage Temperature And Time On The Quality Of Spray Dried Egg Powder, Fallon Polette Salinas Gonzalez Jan 2017

The Effect Of Storage Temperature And Time On The Quality Of Spray Dried Egg Powder, Fallon Polette Salinas Gonzalez

LSU Master's Theses

Dehydration is a good approach for egg preservation. However, dried egg products may still suffer from deterioration if stored in an abused temperature environment or prolonged times. Storage conditions can induce undesirable reactions and loss of functionality and quality. The objective of this study was to evaluate the physicochemical characteristics and functionality of spray dried egg yolk powders, which included plain whole egg (PLWE), free flow yolk (FFY), enzyme modified yolk (EMY), and free flow whole egg (FFWE) stored at 4 °C, 25 °C, 43 °C or 54 °C, over a 2-month period; and provide useful suggestions to maximize quality …
