Individual And Landscape-Level Effects Of Selective Herbicides, Mowing, And Prescribed Fire On Habitat Quality For Northern Bobwhite (Colinus Virginianus), Charles Lynn Kitts

LSU Master's Theses

Northern bobwhite (Colinus virginianus) populations have been declining throughout their range during the past 30 years primarily because of a result of loss of early successional habitat. Specifically, intensive silviculture practices and reduction in the use of prescribed fire has led to this loss. I studied effects of management practices (selective herbicides, mowing, and prescribed fire) on male and covey distribution, and brood-rearing habitats on Jackson-Bienville Wildlife Management Area (JBWMA). Specifically, I used calling surveys to assess landscape characteristics associated bobwhite distribution. I also measured vegetation and arthropod response, using imprinted bobwhite chicks, pitfalls, and sweep nets, to different habitat …

Microsatellite Instability In Squamous Cell Carcinoma And Lichen Sclerosus Of The Vulva, Sidney Joseph Marlborough

LSU Master's Theses

The usefulness of detecting genomic instability in the form of microsatellite instability (MSI) has been examined in a number of cancers. Squamous cell carcinoma (SCC) and adjacent normal and lichen sclerosis (LS) samples were taken from patients with radical vulvectomies. Vulvar SCC samples were compared with adjacent normal samples using four oligonucleotide markers (BAT-25, BAT-26, D10S208 and D10S587) found to be informative with other carcinomas. Using polymerase chain reaction techniques, 30 vulvar SCC DNA samples were examined for MSI. BAT-26 displayed the highest level of MSI and was considered to be the most sensitive marker in studying vulvar SCC. There …

An Analysis Of Cardiovascular And Respiratory Mortality As A Function Of Ambient Ozone And Fine Particulate Matter In The Baton Rouge Air Quality Control Region, Thomas James Wiley Iv

LSU Master's Theses

The Baton Rouge Air Quality Control Region has come under fire due to difficulties in reaching attainment of one-hour daily ozone limitations and its general perception as being a polluted place to live. Ozone is a reactive oxygen species which has been shown to result in damage to biological molecules and is detrimental to human physiology, especially in regards to cardio-respiratory structure and function. In the last decade, fine particulate matter less than 2.5 microns in mean aerodynamic diameter have been identified as a possible pollutant that is affecting public health at levels lower than the EPA’s established limits. PM2.5 …

Spatial Analyses And Growth Of Trees In Selected Bottomland Hardwood Stands, Luben D. Dimov

LSU Doctoral Dissertations

Sustainable management and conservation of the extensive bottomland hardwood forest resource in the southeastern U.S. requires a good understanding of basic structural and competitive relationships within these forests. To gain an insight into these relationships, plot information from stands in Arkansas, Louisiana, and Mississippi were analyzed. The effects of individual tree attributes, distance-dependant, and distance-independent competition measures on 5-yr radial growth of red oak crop trees were examined. Selected species included cherrybark oak (Quercus pagoda Raf.), water oak (Q. nigra L.), and Nuttall oak (Q. nuttallii Palmer). Spatial continuity of tree variables was explored through geostatistical analysis. Finally, spatial distribution …

Modeling Longleaf Pine (Pinus Palustris Mill) Wood Properties Using Near Infrared Spectroscopy, Brian Kipling Via

LSU Doctoral Dissertations

This research demonstrated model development for important wood properties using near infrared spectroscopy (NIR); it considered the effect of outside sources of error, and the ability of NIR to measure fiber morphology. Strength, stiffness, and density were successfully modeled from wood samples taken throughout 10 longleaf (Pinus palustris Mill) trees. Principal components and multiple linear regression were compared for performance in prediction of density, strength, and stiffness. I found both modeling techniques to yield similar prediction accuracies. However, I found that density could be estimated through Beer-Lambert’s law since the absorbance at all wavelengths increased with density. Also, 5 of …

On Analytical Methods And Inferences For 2 X 2 Contingency Table Data Using Wildlife Examples, Richard M. Engeman, George D. Swanson

United States Department of Agriculture Wildlife Services: Staff Publications

The 2 X 2 contingency table is common analytical method for wildlife studies, but inappropriate analyses and inferences are not uncommon. Issues of concern are presented for selecting the appropriate test for analyzing these data sets. These include the choice of test relative to experimental or sampling design and breadth of intended inferences, the careful statement of hypotheses, and analyses with small sample sizes. Examples from the wildlife literature are used to reinforce the statistical concepts.

Internal Phosphorus Loading In Spring Lake: Year 1, Dr. Alan Steinman, Dr. Rick Rediske

Scientific Technical Reports

The rate of phosphorus release from sediments, and the degree to which alum reduces phosphorus release from sediments, was investigated in Spring Lake during the summer of 2003. Triplicate cores were sampled from 4 sites in the lake, and exposed to one of four treatments in the laboratory: 1) oxygen/alum; 2) oxygen/ no alum; 3) nitrogen/alum; or 4) nitrogen/no alum. Both soluble reactive phosphorus (SRP) and total phosphorus (TP) release rates were virtually undetectable in the alum treatments (both with and without oxygen). Low, but detectable, release rates were measured in the oxygen/no alum treatment. The highest release rates were …

Modeling Corrosion In Oxygen Controlled Lbe Systems With Coupling Of Chemical Kinetics And Hydrodynamics-Task V: Fourth Quarterly Report 09/01/2003-11/30/2003, Samir Moujaes, Yitung Chen

Transmutation Sciences Materials (TRP)

The Lead-Bismuth eutectic (LBE) has been determined from previous experimental studies by the Russians and the European scientific community to be a potential material that can be used as a spallation target and coolant for the TRP proposed application. Properly controlling the oxygen content in LBE can drastically reduce the LBE corrosion to structural steels. However, existing knowledge of material corrosion performance was obtained from point-wise testing with only very sparse experimental data. Scientists have noticed that the concentration of oxygen dissolved in the liquid alloy could control the corrosion rate of steels exposed to Pb or Pb-Bi. At high …

Effects Of Radio-Transmitters On Fecal Glucocorticoid Levels In Captive Dickcissels, Kimberly M. Suedkamp Wells, Brian E. Washburn, Joshua J. Millspaugh, Mark R. Ryan, Michael W. Hubbard

United States Department of Agriculture Wildlife Services: Staff Publications

We determined the effects of a leg-harness transmitter on fecal glucocorticoid levels of wild male Dickcissels (Spiza americana) in captivity. During the post-breeding season of 2001, we captured 10 male Dickcissels in central Missouri and housed them in individual pens of an outdoor aviary. We radio-tagged five birds; the other five were captured and handled, but were not radio-tagged. We collected fecal samples every other day prior to attachment (31 July– 21 August) and after attachment (24 August–20 September). Body condition and morphology were similar between control and transmitter-equipped birds. We observed a significant interaction between transmitter attachment …

Tight Coupling Between Soil Moisture And The Surface Radiation Budget In Semiarid Environments: Implications For Landatmosphere Interactions, Eric E. Small, Shirley A. Kurc

Environmental Science and Geology Faculty Research Publications

Observations are used to examine how soil moisture influences the surface radiation budget, ground heat flux, and available energy in semiarid environments. Defining this relationship is critical to understand interactions between the land surface and the atmosphere, in particular assessing if a feedback exists between soil moisture and rainfall anomalies. We use two summers of data collected from semiarid grassland and shrubland ecosystems in central New Mexico. The response of surface radiation budget components and other variables to soil moisture variations are quantified via linear regression. Then, the variations are scaled over the observed range of soil moisture (15% volumetric …

Stability In The Proportion Of Harbor Seals Hauled Out Under Locally Ideal Conditions, Michael Simpkins, David Withrow, Jack Cesarone, Peter Boveng

United States Department of Commerce: Staff Publications

We monitored the haul-out behavior of 68 radio-tagged harbor seals (Phoca vitulina) during the molt season at two Alaskan haul-out sites (Grand Island, August-September 1994; Nanvak Bay, August-September 2000). For each site, we created a statistical model of the proportion of seals hauled out as a function of date, time of day, tide, and weather covariates. Using these models, we identified the conditions that would result in the greatest proportion of seals hauled out. Although those “ideal conditions” differed between sites, the proportion of seals predicted to be hauled out under those conditions was very similar (81.3% for …
