The Impact Of Co2-Related Ocean Acidification On The Molecular Regulation Of Shell Development In The Eastern Oyster (Crassostrea Virginica)., Mackenzie L. Richards
The Impact Of Co2-Related Ocean Acidification On The Molecular Regulation Of Shell Development In The Eastern Oyster (Crassostrea Virginica)., Mackenzie L. Richards
LSU Master's Theses
Eastern oysters (Crassostrea virginica), native to the Gulf of Mexico, are keystone species in estuarine ecosystems and are economically valued. Current research indicates that ocean acidification adversely affects the physiology and morphology of larval oysters, but the molecular mechanisms of this impact remain unstudied. Ocean acidification is contributed to by elevated atmospheric CO2 due to increased anthropogenic activities, causing heightened partial pressure of CO2 (pCO2), and eutrophication from land-based runoff in the Gulf. The objective of this work was to determine the genomic response of the eastern oyster in Louisiana to simulated ocean acidification. …
The Role Of Histone H2a.Z Abundance In Modulating Responses To Phosphorus Deficiency In Rice, Sara Zahraeifard
The Role Of Histone H2a.Z Abundance In Modulating Responses To Phosphorus Deficiency In Rice, Sara Zahraeifard
LSU Doctoral Dissertations
Histone variants contribute to chromatin complexity by creating specialized nucleosomes. Here, to investigate the pattern of H2A.Z histone variant distribution and its role in modulating gene expression in rice (Oryza sativa L.), we performed genome-wide profiling of ARP6-dependent H2A.Z deposition in rice seedlings. We demonstrated that under controlled conditions, the majority of H2A.Z deposition is within protein-coding genes (PCG), and the most highly expressed genes are enriched with H2A.Z at their 5’ ends near the transcription start site (TSS), whereas the medium- to low-expressed genes contain H2A.Z across the entire gene. Based on H2A.Z deposition, we categorized genes into …

Virulence Phenotypes Of Rotylenchulus Reniformis: Evaluation Of Host Status Of Cotton And Utility Of Single Nucleotide Polymorphisms (Snps) For Identification, Churamani Khanal
LSU Doctoral Dissertations
Comparative reproduction and pathogenicity of reniform nematode (Rotylenchulus reniformis) populations derived from single-egg masses and collected form West Carroll (WC), Rapides (RAP), Morehouse (MOR), and Tensas (TEN) parishes in Louisiana were evaluated in microplot and greenhouse trials. Data from microplot trials showed significant differences among isolates of reniform nematode in both reproduction and pathogenicity on upland cotton (Gossypium hirsutum) cultivars Phytogen 499 WRF, Deltapine 1133 B2RF, and Phytogen 333 WRF. Across all cotton cultivars, MOR and RAP isolates had the greatest and the least reproduction values of 331.8 and 230.2, respectively. Reduction in plant dry weight, …
Interaction Of Cocoa Powder With Intestinal Microbiota, Martha M. Escoto Sabillon
Interaction Of Cocoa Powder With Intestinal Microbiota, Martha M. Escoto Sabillon
LSU Master's Theses
Cocoa is the fully fermented and dried seed of the cacao tree (Theobroma cacao L.) which has prebiotic properties, due to their high concentration of polyphenols. Therefore, the ingestion of cocoa could cause changes in the proportions of the intestinal microbiota that can influence the intestinal immune response. The objective of this study was to determine the effect of alkalization process of the cocoa bean in the diversity of the gut microbiota. The samples were “lavado” unprocessed cocoa powder, “natural” unprocessed cocoa powder, “D-11-S” as alkalized cocoa powder, “D-11-B” heavily alkalized cocoa powder, and raw cocoa “shells” and a control …
First Record Of The Non-Native Suckermouth Armored Catfish Hypostomus Cf. Niceforoi (Fowler 1943) (Siluriformes: Loricariidae) From Central America, Wilfredo A. Matamoros, Caleb D. Mcmahan, Carlos R. Mejia, Parker H. House, Jonathan W. Armbruster, Prosanta Chakrabarty
First Record Of The Non-Native Suckermouth Armored Catfish Hypostomus Cf. Niceforoi (Fowler 1943) (Siluriformes: Loricariidae) From Central America, Wilfredo A. Matamoros, Caleb D. Mcmahan, Carlos R. Mejia, Parker H. House, Jonathan W. Armbruster, Prosanta Chakrabarty
Occasional Papers of the Museum of Natural Science, Louisiana State University
We document the first record of Hypostomus cf. niceforoi in Central America. Two specimens of these suckermouth armored catfishes were collected in Lake Nicaragua (Nicaragua) and identified as H. cf. niceforoi. Hypostomus niceforoi is endemic to Andean streams of Colombia, Venezuela, Ecuador, and Peru. We hypothesize that its introduction in Central America is related to the aquarium trade, as is the case of other armored catfish species introductions.

Birds In Peatswamp At Klias Forest Reserve And Environs, Sabah, Malaysian Borneo, Frederick H. Sheldon, Geoffrey Davison, Anna Wong, Robert G. Moyle
Birds In Peatswamp At Klias Forest Reserve And Environs, Sabah, Malaysian Borneo, Frederick H. Sheldon, Geoffrey Davison, Anna Wong, Robert G. Moyle
Occasional Papers of the Museum of Natural Science, Louisiana State University
Periodically from 1998-2004, we surveyed birds in the Klias Forest Reserve, which is one of the last remaining pockets of peatswamp in western Sabah. We report here on those surveys. We also review prior work on birds in peatswamp and swamp forest in the Klias-Sipitang region of Sabah as it relates to the conservation of habitat and birds specialized on peatswamp. Peatswamp forest is in jeopardy from development and fires throughout Borneo, and particularly in the Malaysian State of Sabah, which had very little to start. Peatswamp in the Klias area is of particular importance for conservation and bird watching …

In the southwestern Amazon Basin, large areas of habitat are comprised predominantly of Guadua bamboo. Many bird species occur in or specialize on Guadua-dominated habitats, but little is known about the taxonomy, distribution, and evolutionary history of this avian assemblage. During 2011, we surveyed the surroundings of Iberia, an area with many large Guadua stands in the southern Peruvian Amazon. We found many Guadua specialist bird species and discovered a surprising Andean element to the local avifauna. We present information on Guadua specialists, Andean species, birds of open habitats, and avian migration and reproduction. We provide accounts for species …

Mtbindingsim: Simulate Protein Binding To Microtubules, Julia T. Philip, Charles H. Pence, Holly V. Goodson
Faculty Publications
Summary: Many protein–protein interactions are more complex than can be accounted for by 1:1 binding models. However, biochemists have few tools available to help them recognize and predict the behaviors of these more complicated systems, making it difficult to design experiments that distinguish between possible binding models. MTBindingSim provides researchers with an environment in which they can rapidly compare different models of binding for a given scenario. It is written specifically with microtubule polymers in mind, but many of its models apply equally well to any polymer or any protein–protein interaction. MTBindingSim can thus both help in training intuition about …

Species Limits Within The Mexican Garter Snakes Of The Thamnophis Godmani Complex, Douglas A. Rossman, Frank T. Burbrink
Species Limits Within The Mexican Garter Snakes Of The Thamnophis Godmani Complex, Douglas A. Rossman, Frank T. Burbrink
Occasional Papers of the Museum of Natural Science, Louisiana State University
The highly variable Thamniphis godmani complex of southern Mexico, comprised of four apparently allopatric populations, was examined by using 28 morphological characters scored on 214 specimens. Character values were tested with univariate and multivariate statistics to determine if populations are morphologically distinct. The results suggest that the four populations represent independently evolving lineages. Four species, three previously undescribed, are recognized in the T. godmani complex. A lectotype is designated for T. godmani. For each species, a diagnosis description of holotype or lectotype, summary of interspecific variation, and statement of distribution are provided. Comparisons are made with T. errans, alleged to …
