Using Forward-Looking Infrared Radiography To Estimate Elk Density And Distribution In Eastern Kentucky, Lauren M. Dahl Jan 2008

Using Forward-Looking Infrared Radiography To Estimate Elk Density And Distribution In Eastern Kentucky, Lauren M. Dahl

University of Kentucky Master's Theses

Elk (Cervus elaphus) in eastern Kentucky appear to have increased in number since reintroduction in 1997, but rugged landscapes and cryptic elk behavior have precluded use of typical population survey methods to accurately estimate population size. In December 2006, I used forward-looking infrared radiography (FLIR) to survey the elk population in eastern Kentucky. Elk locations identified by FLIR were used to create a landscape based model to estimate the density distribution of elk within a 7,088 km2 core area of the elk restoration zone. FLIR detected 76% of elk groups of < 10 individuals and 100% of elk groups of ≥ 10 individuals. The density of elk was positively associated with the amount of herbaceous area, herbaceous edge, herbaceous area weighted mean patch fractal dimensions, proximity to release sites, the number of elk released at each site and urban core area index, and negatively associated with road density. My model estimated the elk population at 7,001 (SE = 772, 95% CI = 5,488- 8,514) individuals within the core area, 53% of which were < 10 km from release sites. The predicted elk distribution pattern and abundance estimate derived from this model will be important for wildlife managers in successfully managing the Kentucky elk population.

Comparative Aspects Of The Control Of Posture And Locomotion In The Spider Crab Libinia Emarginata, Andres Gabriel Vidal Gadea Jan 2008

Comparative Aspects Of The Control Of Posture And Locomotion In The Spider Crab Libinia Emarginata, Andres Gabriel Vidal Gadea

LSU Doctoral Dissertations

The study of pedestrian locomotion in crustaceans has largely focused on forward walking macrurans, or sideway walking brachyurans. The spider crab, Libinia emarginata is a brachyuran that, unlike its close relatives, preferentially walks forward. The phylogenetic position, behavioral preference, and amenability to experimental techniques make spider crabs an attractive model for comparative studies of crustacean locomotion. This dissertation looks at the neuroethology of forward walking in L. emarginata. I described the skeletal, muscular, and neural anatomy of the walking machinery of L. emarginata and found adaptations at each level that reflect its walking preference. The ranges of motion of leg …

Brachial Artery Flow Mediated Vasodilation: Effect Of Chemical Analytes, Diet, Exercise, And Genetic Markers, Joanie Brocato Wilson

LSU Doctoral Dissertations

The goal of this research was to gain a better understanding of interplay between molecular biology, physiology, biochemistry, functionality with disease and interventions. The primary findings of the first study were that there was a significant inverse correlation between homocysteine and brachial artery flow mediated dilation (BAFMD) and baseline brachial artery diameter. Interestingly, there was a significant difference in BAFMD between methylene tetrahydrofolate reductase (MTHFR) genotype groups. Regression analysis indicated that the MTHFR genotype, homocysteine and age were significant predictors of BAFMD. The second study revealed that vascular reactivity as measured by BAFMD was modifiable. A meta-analysis of 22 intervention …

Is Oxidative Stress The Cause Of Death When Recalcitrant Spartina Alterniflora Seeds Are Dried?, James Hammond Chappell Jan 2008

Is Oxidative Stress The Cause Of Death When Recalcitrant Spartina Alterniflora Seeds Are Dried?, James Hammond Chappell

LSU Doctoral Dissertations

Recalcitrant seeds, which die when desiccated, can be difficult to study because of their generally large size, high metabolism, and poor storage properties. However, recalcitrant seeds from the salt-marsh grass Spartina alterniflora are unique when compared to most other recalcitrant species because the seeds are dormant and small; Spartina pectinata and S. spartinae, which produce orthodox seeds, can be used as controls. Because of these somewhat rare characteristics, S. alterniflora is a good model system to study recalcitrance. In the present study, the following physiological parameters were examined: Cardinal temperatures for germination, a viability test to determine if seeds are …

"I Will Learn You Something If You Listen To This Song": Southern Women Writers' Representations Of Music In Fiction, Courtney George Jan 2008

"I Will Learn You Something If You Listen To This Song": Southern Women Writers' Representations Of Music In Fiction, Courtney George

LSU Doctoral Dissertations

This dissertation offers a rhetorical analysis of the formation of women’s memory, history, and communities in intersections of musical and literary expression in the American South, a region graced with a vital but underexamined tradition of female musicianship. Recent scholars have deconstructed the imagined narrative of southern culture as static, patriarchal, and white to uncover alternative stories and cultures that exist outside of canonical literature. This project significantly expands current understandings of these conflicting narratives by investigating how women writers recall, reclaim, and re-envision women’s roles in southern music to challenge, comply, and/or identify with women’s prescribed place in the …

Bile Salts As Olfactory And Gustatory Stimuli In The Channel Catfish, Shane Howell Rolen Jan 2008

Bile Salts As Olfactory And Gustatory Stimuli In The Channel Catfish, Shane Howell Rolen

LSU Doctoral Dissertations

A chemotopic map of biologically relevant odorants (that include amino acids, bile salts and nucleotides) exists in the olfactory bulb (OB) and forebrain (FB) of channel catfish, Ictalurus punctatus (Chapter one). Neurons processing bile salt odorant information lie medially within these bilaterally symmetric structures; however, information as to how single neurons discriminate and process this odorant information is lacking. Chapters two and three of the dissertation identify the range of odorant bile salt molecules that excite these neurons [i.e. the excitatory molecular receptive range (EMRR)] within the bile salt chemotopic zones of the OB and FB. The results of the …

Trophic Control Of Saltmarsh Invertebrates, David Samuel Johnson Jan 2008

Trophic Control Of Saltmarsh Invertebrates, David Samuel Johnson

LSU Doctoral Dissertations

Top-down (consumer) versus bottom-up (resource) control of food webs has long interested ecologists. Here, I take advantage of a full-factorial design of ecosystem-wide manipulations of nutrient additions (loading rates 10x above background) and the significant reduction (~60%) of a key predator, the killifish Fundulus heteroclitus, in the tidal creeks of the Plum Island Estuary, Massachusetts. Prior to manipulations, annelids numerically constituted 97% of the infaunal community and the largest scale (creeks) accounted for little spatial variability in annelid populations and diversities. Tidal creeks were similar based on diversity indices, abundance, and community patterns, suggesting the tidal creeks are appropriate replicates/experimental …

Avian Diversification In The Afrotropics, Ben D. Marks Jan 2008

Avian Diversification In The Afrotropics, Ben D. Marks

LSU Doctoral Dissertations

Widespread bird species endemic to the lowlands of the Guineo-Congolian rainforest of Africa have traditionally been thought to lack substantial intraspecific structure. This view owes largely to their widespread distributions coupled with the absence of discrete geographic variation in plumage. In the following chapters I examine the phylogeographic patterns of three such species using a combination of molecular and morphometric data. The three species investigated are the Green Hylia (Hylia prasina), the Red-tailed Bristlebill (Bleda syndactylus), and the Yellow-whiskered Greenbul (Andropadus latirostris). Using the phylogeographic patterns from these data, I assess 1) models of rainforest species diversification, 2) current taxonomy, …

The Diet Of Saltmarsh Consumers, Kari Ann Galvan Jan 2008

The Diet Of Saltmarsh Consumers, Kari Ann Galvan

LSU Doctoral Dissertations

Salt marshes are areas of high primary production that in turn support high secondary production. Macrophytes, phytoplankton and a variety of benthic algae all contribute to the high primary productivity. Each has the potential to contribute to the saltmarsh food web making it difficult to determine organic matter resources important to secondary production in salt marshes. Furthermore, our understanding of saltmarsh food webs is complicated by anthropogenic effects such as nutrient inputs and exploitation of key predators. I utilized a combination of natural abundance stable isotopes, isotope tracer additions, gut content analysis and manipulative experiments to determine the diets of …

Bioanalytical Methods For Studies Of Homocysteine And Novel Cardiovascular Disease Indicators, Arther T. Gates Jan 2008

Bioanalytical Methods For Studies Of Homocysteine And Novel Cardiovascular Disease Indicators, Arther T. Gates

LSU Doctoral Dissertations

This dissertation explores the development of analytical methods for studies of CVD biomarkers and related biomolecular indicators. Initially, spectroscopic studies were conducted to investigate the chemical reactivity of homocysteine (Hcy), an independent CVD risk factor and serological biomarker. Consequently, we proposed an alternate theory for in vivo Hcy clearance based on spontaneous pyridoxal tetrahydrothiazine (PT) formation from Hcy and pyridoxal. The validity of PT-assisted Hcy clearance was further evaluated by use of capillary electrophoretic methods, which allowed rapid monitoring of protein oligomerization in PT-protein reaction mixtures. The results of these studies suggest that PT formation is a plausible mechanism for …

Seeing And Believing: Mandatory Ultrasound And The Path To A Protected Choice, Carol Sanger Jan 2008

Seeing And Believing: Mandatory Ultrasound And The Path To A Protected Choice, Carol Sanger

Faculty Scholarship

Several state legislatures now require that before a woman may consent to an abortion, she must first undergo an ultrasound and be offered the image of her fetus. The justification is that without an ultrasound, her consent will not be fully informed. Such legislation, the latest move in abortion regulation, supposes that a woman who sees the image will be less likely to abort. This Article explores how visual politics has combined with visual technology, and how law has seized upon both in a campaign to encourage women to choose against abortion. While rarely analyzed, the significance of seeing, or …
