Growth Response Of Mixed Native Grass Stands To Simulated Grazing In Mississippi: Forage Yield And Species Dynamics, Vitalis Wilbald Temu

Theses and Dissertations

Some native warm-season forage grasses [indiangrass (IG, Sorghastrum nutans), big bluestem (BB, Andropogon gerardii) and little bluestem (LB, Schizachyrium scoparium)] are gaining popularity for improving summer forage production and wildlife habitat in the southeastern USA. Paucity of information about appropriate harvest management limits their restoration success. An experiment was conducted to assess effects of harvest intervals (30-, 40-, 60-, 90 or 120-d) and harvest duration on forage yield and quality, plant growth, sward structure and botanical composition of their mixed stands at Bryan Farms, Clay County, MS. Total season forage was greatest for 30-d and more from first (8472 kg …

Oyster Reefs As Natural Breakwaters Mitigate Shoreline Loss And Facilitate Fisheries, Steven B. Scyphers, Sean P. Powers, Kenneth L. Heck Jr., Dorothy Byron

University Faculty and Staff Publications

Shorelines at the interface of marine, estuarine and terrestrial biomes are among the most degraded and threatened habitats in the coastal zone because of their sensitivity to sea level rise, storms and increased human utilization. Previous efforts to protect shorelines have largely involved constructing bulkheads and seawalls which can detrimentally affect nearshore habitats. Recently, efforts have shifted towards “living shoreline” approaches that include biogenic breakwater reefs. Our study experimentally tested the efficacy of breakwater reefs constructed of oyster shell for protecting eroding coastal shorelines and their effect on nearshore fish and shellfish communities. Along two different stretches of eroding shoreline, …

Slob, A Slowpoke Channel Binding Protein, Regulates Insulin Pathway Signaling And Metabolism In Drosophila., Amanda L. Sheldon, Jiaming Zhang, Hong Fei, Irwin B Levitan

Department of Neuroscience Faculty Papers

There is ample evidence that ion channel modulation by accessory proteins within a macromolecular complex can regulate channel activity and thereby impact neuronal excitability. However, the downstream consequences of ion channel modulation remain largely undetermined. The Drosophila melanogaster large conductance calcium-activated potassium channel SLOWPOKE (SLO) undergoes modulation via its binding partner SLO-binding protein (SLOB). Regulation of SLO by SLOB influences the voltage dependence of SLO activation and modulates synaptic transmission. SLO and SLOB are expressed especially prominently in median neurosecretory cells (mNSCs) in the pars intercerebralis (PI) region of the brain; these cells also express and secrete Drosophila insulin like …

Role Of Autophagy In Radiosensitization Of Breast Tumor Cells, Molly L. Bristol

Theses and Dissertations

In MCF-7 breast tumor cells, ionizing radiation promoted autophagy that was cytoprotective; pharmacological or genetic interference with autophagy induced by radiation resulted in growth suppression and/or cell killing (primarily by apoptosis). The hormonally active form of vitamin D, 1,25D3, also promoted autophagy in irradiated MCF-7 cells, sensitized the cells to radiation and suppressed the proliferative recovery that occurs after radiation alone. 1,25D3 also enhanced radiosensitivity and promoted autophagy in MCF7 cells that overexpress Her-2/neu as well as in p53 mutant Hs578t breast tumor cells. In contrast, 1,25D3 failed to alter radiosensitivity or promote autophagy in the BT474 breast tumor cell …

The Potential For Eutrophication Mitigation From Aquaculture Of The Native Oyster, Crassostrea Virginica, In Chesapeake Bay: Quantitative Assessment Of An Ecosystem Service, Colleen Higgins

Theses and Dissertations

Native oysters have been promoted as a means to improve water quality in Chesapeake Bay. This project added important insights into the potential of oyster aquaculture to process and remove nutrients from Bay waters. Results clarified that nutrient removal of nitrogen (N), phosphorous (P), and carbon (C) through harvest of cultivated oyster biomass can be quantified and modeled with high levels of statistical confidence. A simple, yet accurate, method is now available for estimating the amount of nutrients removed via harvesting aquacultured oysters. Based on model estimates, 106 harvest sized oysters (76 mm TL) remove 132 kg TN, 19 kg …

Scarification And Cultural Practice Of Four Lupine Species Native To The Great Basin, Covy Dennis Jones

Theses and Dissertations

The Great Basin is North America's largest desert, encompassing 135 million acres. Grazing and other anthropogenic activities in the Great Basin have put heavy demands on the landscape over the last 150 years. Heavily grazed areas lack diversity which allows the spread of exotic weed species. Cheatgrass (Bromus tectorum L [Poaceae]) has invaded and shortened fire frequency intervals from historic 30—100 years to as few as three to five years. Post-fire reseeding of native species is requisite for restoration of highly invaded ecosystems thus, preventing complete conversion to exotic weeds. Most native shrubs and grasses are available for restoration …

Academic Websites And Minority Portrayal: A Content Analysis, Aymara Jimenez

Theses and Dissertations

The Internet has changed the way society communicates with one another. One of the organizations that utilize the Internet in order to communicate with their audience is universities.

Defining “Style” For Instructional Design Projects, Shalin Hai-Jew

SIDLIT Conference

Complex instructional design projects typically have quite a few team members, principal investigators (PIs) who have to uphold grant requirements, and multiple “moving parts.” To handle complexity, some instructional designers work with the instructional development team in order to co-create an instructional design stylebook. Stylebooks incorporate team member contact information, team member roles, course build guidelines, technological standards, workflows, timelines, templating, alpha and beta testing, and other basic information. Such stylebooks are necessarily evolving and living workplace documents used throughout the lifespan of the work.

Rumbling In The Benthos: Acoustic Ecology Of The California Mantis Shrimp Hemisquilla Californiensis, E. Staaterman, C. Clark, A. Gallagher, M. Devries, T. Claverie, S. Patek

Faculty Publications, Biological Sciences

Although much research has focused on acoustic mapping and exploration of the benthic environment, little is known about the acoustic ecology of benthic organisms, particularly benthic crustaceans. Through the use of a coupled audio–video system, a hydrophone array, and an autonomous recording unit, we tested several hypotheses about the field acoustics of a benthic marine crustacean, Hemisquilla califor­niensis. Living in muddy burrows in southern California, these large mantis shrimp produce low frequency ‘rumbles’ through muscle vibrations. First, we tested whether acoustic signals are similar in the field and in the laboratory, and discovered that field-produced rumbles are more acoustically and …

Stability Of Diluted Adenosine Solutions In Polyvinyl Chloride Infusion Bags, Melissa Kaltenbach, David Hutchinson, Jessica E. Bollinger, Fang Zhao

Doctoral External Publications

Purpose The stability of diluted adenosine solutions in polyvinyl chloride infusion bags was studied.

Methods Adenosine 50-, 100-, and 220-μg/mL solutions were prepared in 50-mL polyvinyl chloride (PVC) infusion bags containing 0.9% sodium chloride injection or 5% dextrose injection and stored at room temperature (23–25 °C) or under refrigeration (2–8 °C). Each sample of every combination of concentration, diluent, and storage temperature was prepared in triplicate, yielding 36 samples. The samples were assayed using a stability-indicating, reverse-phase high-performance liquid chromatographic method immediately after preparation (time zero) and at 24 hours, 48 hours, 7 days, and 14 days. pH was measured …

Transcendental Mirrors: Thoreau's Pond, Poe's Sea, And Melville's Ocean, Leslie Straight

LSU New Orleans Theses and Dissertations

Three seminal 19 th-century North American literary works feature bodies of water which serve both as key elements in their narrative structure and as symbolic entities within their meaning systems. The protagonists in Henry David Thoreau’s Walden, Edgar Allan Poe’s A Narrative of Arthur Gordon Pym of Nantucket, and Herman Melville’s Moby-Dick literally define themselves in terms of their relation to these bodies of water. The best way to determine the function of water in the texts is to analyze the initial relationship between water and the central character, the way that water serves as a reflection of the Self, …

Defending Desire: Resident Activists In New Orleans‟ Desire Housing Project, 1956-1980, Takashi Michael Matsumaru

LSU New Orleans Theses and Dissertations

The Desire Housing Project opened in 1956 as a segregated public housing development in New Orleans‟ Upper Ninth Ward. The Desire neighborhood, one of the few neighborhoods in the city where black homeownership had been encouraged, was transformed by the project. Hundreds of former Desire residents were displaced by the mammoth project, which became home to more than 13,000 residents by 1958. Built on what had once been a landfill, the Desire Housing Project came to epitomize the worst in public housing, before it was torn down by 2001. Although the project was isolated from the rest of the city …

Factors That Affect Harem Stability In A Feral Horse (Equus Caballus) Population On Shackleford Banks Island, Nc, Jessa Madosky

LSU New Orleans Theses and Dissertations

Mammal species often live in social groups, but the factors that promote group cohesion can be difficult to analyze due to the prevalence of strong group affiliations. Feral horses maintain stable harems of one or two males and several females, and harem stability is strongly related to individual fitness. Anecdotal evidence and an early study in the non-breeding season suggest that management of the Shackleford Banks island horses with immunocontraception reduces harem stability in the population, providing an opportunity to study the factors that influence harem stability. I investigated the effects of the immunocontraceptive PZP on harem stability during the …

Metabolism And Cryo-Sensitivity Of Domestic Cat (Felis Catus) And Cheetah (Acinonyx Jubatus) Spermatozoa, Kimberly Terrell

LSU New Orleans Theses and Dissertations

Teratospermia (ejaculation of ≥ 60% structurally abnormal spermatozoa) is prevalent among felids facing extinction risk, including the cheetah. This trait also occurs in certain domestic cat populations, providing a valuable research model. Multiple components of sperm function are disrupted in teratospermic cats, and even structurally normal spermatozoa from these ejaculates may be functionally compromised. Teratospermic ejaculates are highly sensitive to damage during cryopreservation, limiting the success of genome resource banking programs for species conservation. Although both teratospermia and cryopreservation are linked to disruptions in multiple energy-dependent sperm processes, the metabolism of these cells has not been investigated. This project explored …

People's Perceptions Of Women's Stereotypes In Films: A Survey Of University Students, Baker Hasan Alkarimeh

Student Theses and Dissertations

The film industry has stereotyped women for several decades led by the dominance of white males in this virtual world. Women in this filmic world face many challenges related to their roles, sex, race, and strive to get rid of male hegemony. This study examines the perceptions of people of women's stereotypes in films through surveying eight hundred and four participants. It divides the stereotypes of women in films into women's roles; women as a body image; women as an object and subject of violence; and women and race. By using the cultivation theory, this study examines the perceptions of …

Simin Daneshvar's Savushun: Examining Gender Under Patriarchy, Yasaman Jahed

LSU New Orleans Theses and Dissertations

The author covers issues of gender and Iranian national identity as reflected in Iran’s first published woman novelist, Simin Daneshvar. Her novel, Savushun, is the first novel to be published by an Iranianwoman in 1969. The novel depicts Iran at the start of the country’s governmental factions in 1941 when Reza Shah Pahlavi overthrew years of Iranian dynasty and established a monarchy. This thesis explores how the novel is a vital part of Iran’s historical literature as well as essential to the present day discussion of gender and politics, especially for women within the patriarchal paradigm.

Characterization Of The Desorption Electrospray Ionization Mechanism Using Microscopic Imaging Of The Sample Surface, Michael Craig Wood

Theses and Dissertations

Desorption electrospray ionization (DESI) is an ambient ionization technique for mass spectrometry. This solvent based desorption ion source has wide applicability in surface analysis with minimal sample preparation. Interest in improving detection limits, broadening applications, and increasing the spatial resolution for chemical imaging has led to studies of the DESI mechanism. An inverted microscope has been used to image interactions between the DESI spray and test analytes on a glass surface. Microscopic images recorded with millisecond time resolution have provided important insights into the processes governing analyte transport and desorption. These insights are the basis of a rivulet-based model for …

Book Review: Knocking On Heaven's Door, Scott D. Peterson

Communication Faculty Publications

Since the late nineteenth and early twentieth centuries, baseball has had more than its share of apologists to proclaim the game's virtues and unique qualities-how the game lends itself to narrative, how it's a meritocracy that rewards hard work and perseverance, or how it acts as a conduit to the American Dream. What baseball literature needs in he present day and age is more writers to tell the whole story-and Marty Dobrow's Knocking on Heaven's Door does just that.
