Impact Of Development On Freshwater Turtle Populations Of Coastal South Carolina: An Examination Of Land Use And Road Density, Andre Dominguez

Electronic Theses and Dissertations

Previous studies (Haxon 2000; Steen and Gibbs 2004; Marchand and Litvaitis 2004; Aresco 2005) have demonstrated that urbanization and development have disproportionally adverse affects on female turtles. In order to test this paradigm I caught 301 turtles (primarily Trachemys scripta scripta) in ten ponds (5 impacted and 5 unimpacted) across coastal South Carolina. Not only do coastal South Carolina turtles not follow the same male biased pattern of many other studies, there was an overall female bias (154:95). Turtle metrics were between the types of sites existed as well, indicating larger/older population of turtles in unimpacted sites. Water quality parameters …

Tide-Dependent Predation Patterns Of Piscivorous Fishes In Shallow Estuarine Creeks, Matthew Ross Helms

Electronic Theses and Dissertations

The distribution and foraging behavior of predatory salt marsh fishes is shaped by the movements of prey, many of whom seek shelter in shallow and tributary creeks. I hypothesized that the distribution of piscivorous fishes in marsh creek channels would differ with proximity to the mouths of intertidal creeks and with tidal stage. Custom-built trotlines baited with live minnows were deployed during four discrete tidal stages at two microhabitats in main creek channels: (1) adjacent to intertidal creek mouths, and (2) along straight banks in North Inlet estuary, South Carolina. Catch-per-unit-effort of predatory fishes was significantly higher (Wilcoxon signed-rank tests, …

Built For Boyhood?: A Proposal For Reducing The Amount Of Gender Bias In The Advertising Of Children's Toys On Television, Nareissa L. Smith

Vanderbilt Journal of Entertainment & Technology Law

While the last half-century has seen a dramatic increase in the number of US women in the workforce, women remain under represented in STEM (Science, Technology, Engineering, and Mathematics) fields. For years, researchers and social commentators have tried to explain the persistence of this gender gap. Some have even argued that genetic differences explain women's inability to excel in the hard sciences. This Article asserts that the impact of socialization on children's educational and occupational choices has been greatly underestimated. Specifically, the toys that are marketed to boys teach spatial skills that prepare boys for STEM careers. Conversely, the toys …

It Takes A Village: Placing Middle Rocky Mountain High Altitude Residential Sites Of The Late Prehistoric Firehole Phase Into A Broader Regional Context, Bryon Alan Schroeder

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation presents three separate articles in different stages of peer-review all focused on late Late Prehistoric (AD 1300 to contact) residential occupations, in the Wind River Range and Shirley Basin of Wyoming. These articles cover survey results in in the Wind River Range of Wyoming, Shoshone ethnic interpretations associated with Late Prehistoric artifact assemblages, and a lithic analysis from the excavated interior of domestic structure at an alpine and basin location of the Firehole Phase. These articles broaden the research agenda of high-altitude sites to downplay the role of ethnicity and include adjacent sites of the Wyoming Basin. In …

Dynamic Motions Of The Alpha Subunit Of Heterotrimeric G Proteins In The Nucleotide- And Ric-8a-Bound States, Labe Adam Black

Graduate Student Theses, Dissertations, & Professional Papers

The conformational changes and segmental dynamics involved in the G alpha-subunit of heterotrimeric G proteins have been investigated for 3 separate binding states by using binning-time-dependent single-molecule F÷rster resonance energy transfer (smFRET) of freely diffusing proteins and time-resolved fluorescence anisotropy. The bound states include Ric-8A (Resistance to Inhibitors of Cholinesterase-8A (Miller, Emerson et al. 2000; Miller and Rand 2000; Tall, Krumins et al. 2003)), a guanine nucleotide exchange factor (GEF), and nucleotides GDP and GTP. To analyze the smFRET data, energy transfer efficiency histograms were constructed at binning times varied from 1000 to 2,500 ╡s. Then the conformational equilibria and …

A Zooarchaeological Study Of Generational Decision-Making: Modeling Subsistence And Demographic Change In Late-Holocene Occupations Of Housepit 54 At The Bridge River Site (Eerl4), Mid-Fraser, B.C., Matthew Joseph Walsh

Graduate Student Theses, Dissertations, & Professional Papers

The Bridge River site is a winter pithouse village near the confluence of the Bridge and Fraser Rivers in the Mid-Fraser Canyon that was occupied periodically from as early as 1800BP to the mid-19th century. Prentiss et al. (2008) divide the range of occupations into four Periods: Bridge River (BR) 1, c. 1800-1600BP, BR2, c. 1600-1300BP, a short-lived BR3, c. 1300-1100BP (by the end of this period the village appears to have been largely abandoned), and BR4, a late reoccupation of the site, c. ~500 to 100BP (Prentiss et al. 2008, 2011, 2012). During BR2 and into BR3, between 1500-1100BP, …

The Habitat Of European Brown Bears In Northern Spain: Mapping Habitat Fragmentation And Potential Connectivity, Alma D. Pacheco

Graduate Student Theses, Dissertations, & Professional Papers

The European brown bear in northern Spain is considered to be an endangered species whose habitat has been fragmented into two subpopulations due to habitat loss and lack of connectivity. The importance of improving connectivity and preventing more habitat destruction is vital to recover the species in this region. This research looks at spatial and temporal variations of brown bear habitat by mapping the conditions of habitat fragmentation and potential connectivity at a regional extent. This research examines net changes of brown bear habitat fragmentation between 1990-2000, 2000-2006, and overall 1990-2006; and the degree of brown bear habitat connectivity between …

Cows And Plows: Science-Based Conservation For Grassland Songbirds In Agricultural Landscapes, Marisa K. Lipsey

Graduate Student Theses, Dissertations, & Professional Papers

Temperate grasslands are among earth’s most imperiled ecosystems. In North America, steep declines of endemic songbird populations indicate that grassland loss and degradation may be approaching critical levels. Grasslands are agricultural landscapes largely (~85%) under private ownership with little formal protection status. Remaining bird populations depend on grazing lands that have not been converted to cropland. We combine regional data from a hotspot for grassland bird diversity (northeast Montana, USA; 26,500-km2) with continental data spanning the northern Great Plains (1,000,000-km2) to evaluate how land use and management influence bird distribution and abundance. Regionally, habitat used by seven grassland specialists spanned …

Wilderness And Epistemic Wildness, John T. Stanfield

Graduate Student Theses, Dissertations, & Professional Papers

The traditional concept of wilderness was a product of the time out of which it came. Times have changed. The social context of conservation, how humans affect nature, and scientific understanding of how ecosystems function have all shifted in ways that make the wilderness idea problematic. The values that people found in wilderness are still relevant, however. It is the way that they are tied together in the concept of wilderness that has become a problem.

I propose a revised concept of wilderness that meets the concerns of critics of wilderness, and accounts for the tension between the wild and …

A Model For Determining Drivers Of Phenology In Western United States Rangelands, Joseph R. St. Peter

Graduate Student Theses, Dissertations, & Professional Papers

Plant phenology has long been used as an indicator of climate. Recent changes in plant phenology are evidence of the influence of climate change. Modeling plant phenology has become an effective tool to understand the impacts of climate change. Using machine learning techniques I developed a modeling process for accurately predicting phenology across a diverse landscape. This model uses individual site data to set site specific climate thresholds for plant phenology. This model also identifies the limiting factors to vegetation phenology for rangelands in the western United States. NDVI remotely sensed data was used to quantify land surface phenology and …

Sacred Zones: Examing Wilderness In Yellowstone, Maine And Russia, Lily S. Vonderheide

Graduate Student Theses, Dissertations, & Professional Papers

This thesis seeks to examine issues of resource conservation and recreational access in three regions of immense historical and ecological significance: Yellowstone National Park, the North Woods of Maine, and the protected nature reserve system of Siberia. By applying a combination of direct professional experience, current research and ongoing environmental policy action, the thesis attempts to provide an accurate picture of current and future challenges facing the three regions. Part I, “Yellowstone Paradox,” traces the roots of Yellowstone’s restrictions on recreational boating access in a post-WWII discourse of consumer recreation, the development of a sustainability ethic and its deployment as …

La Manzana Mordida: Sexo Y Religión En El Cine De Luis Buñuel, Micaela Downey

Graduate Student Theses, Dissertations, & Professional Papers

La extensa y variada obra fílmica de Luis Buñuel permite observar la repetición obsesiva de motivos, imágenes y objetos que constituyen lo que podría denominarse el universo personal de Buñuel. La proliferación de zapatos, pies, cajas misteriosas y armas de fuego (sin olvidar los tambores de Calanda, los insectos y las gallinas) ha atraído la atención de la crítica convirtiéndolos en objetos detallados de análisis. Este ensayo no intenta proponer una “obsesión” más, sino reparar en un motivo que, a pesar de su recurrencia (y, por lo tanto, de su importancia) ha pasado inadvertido: la reescritura de la historia bíblica …

The Last Wolves Of Isle Royale, Kasey Rahn

Graduate Student Theses, Dissertations, & Professional Papers

Isle Royale National Park, located in Michigan, is home to a wolf population that is in decline due to complications from inbreeding. Scientists and managers struggle to decide whether to intervene. Some scientists promote bringing new wolves to the island to restore the population because they say the decline is human-caused. Others promote “watchful waiting.” To date, the National Park Service has not interceded and is currently undergoing a management planning process. The issue raises questions about what it means to manage wildlife in an era of change. Should humans intervene to protect wildlife in the face of climate change …

Hypothyroidism And The Development Of Hypertension, Kaleb Short

All Graduate Theses, Dissertations, and Other Capstone Projects

Low thyroid hormone (TH) in adulthood is associated with increased risk of cardiovascular disease, including risk of hypertension. The Spontaneously Hypertensive Rat (SHR), exhibits alterations in thyroid function when compared to normotensive controls. Interestingly, inhibiting thyroid gland function before 4 weeks of age prevented hypertension in the SHR, indicating that TH is involved in the etiology of SHR hypertension. However, these studies utilized tail-cuff photoplethysmography (PPG), which is known to have stress-induced artifacts, and did not compare effects in the normotensive parent strain Wistar Kyoto (WKY) rat. Therefore, it is uncertain whether TH is responsible for an elevation in baseline …

Sun-Compass Orientation During Natal Dispersal In Hatchling Blanding's Turtles (Emydoidea Blandingii), Meredith Anne Schlenner

All Graduate Theses, Dissertations, and Other Capstone Projects

Blanding's turtle hatchlings emerge from their natal nests naïve to environmental stimuli and primarily sense visual cues on the horizon as a dispersal target. During a period of hours or days, hatchlings develop a compass mechanism that allows them to maintain a direction of travel, even when the target is not visible. We examined the dispersal directions of Blanding's turtle hatchlings captured during dispersal by translocating them into a circular arena in a field of corn in order to measure their dispersal direction guided by a compass mechanism. To test for use of a sun compass, a magnetic compass, or …

Hydrologic And Temperature Regime Influence On Growth And Recruitment Of Fishes In An Upper Midwest Riverine Ecosystem, Brett Donald Nelson

All Graduate Theses, Dissertations, and Other Capstone Projects

The natural flow regime is often identified as the primary driver of ecological integrity in rivers. The Minnesota River basin is characterized by a row-crop agricultural landscape with an extensive network of drainage tiles and ditches to improve land productivity. Intensive surface and subsurface drainage alters flow regimes, increasing the magnitude and frequency of high flows. Changes in river hydrology lead to alterations in geomorphology, including increased bank erosion, channel widening, and downward incision that can lead to floodplain disconnection. Disruption of historical hydrology can alter energy flow and connection to specialized habitats subsequently affecting important aquatic communities and populations …

Traditional Methods Versus Tprs: Effects On Introductory French Students At A Medium-Sized Public University In The Midwestern United States, Rishani Samari Merinnage De Costa

All Graduate Theses, Dissertations, and Other Capstone Projects

The purpose of this study was to measure the effectiveness of introducing a Teaching Proficiency through Reading and Storytelling (TPRS) approach in a French immersion classroom in comparison with a method which does not incorporate a story context within the lesson. This research was conducted in an introductory college level classroom setting. It is hypothesized that the language skills of the students in the experimental group using the TPRS method would show greater improvements on measures of listening, vocabulary, culture, grammar and writing abilities than those taught using methods which do not incorporate the story context. The research utilized a …

The Crypt People From The Cathedral Basilica Of Saints Stanislaus And Vladislaus, Vilnius, Lithuania: Reconstruction Of Life Histories Using Stable Isotope Analysis, Kaylee Schotten

Electronic Theses and Dissertations

Stable isotope analyses of multiple tissue types have been used to reconstruct life histories of individuals from past populations. This thesis presents the life history reconstructions of a unique population recovered from a 16th to 18th century cathedral crypt located in Vilnius, Lithuania. The sample consists of 23 individuals (21 males, one possible female, and one juvenile). Stable carbon, nitrogen, and oxygen isotope analyses were performed on bone and dentin collagen, and on bone and enamel hydroxyapatite, resulting in eight isotope values per individual, providing both childhood and adult dietary and migration information. For bone collagen the average δ13C isotope …

Timp-1 Activates A Unique Cardiac Stem Cell Population, Cd63+Ve/C-Kit+Ve, Thereby Enhancing Cardiac Differentiation, And Protects The Heart From Adverse Cardiac Remodeling Following Myocardial Infarction, Latifa Abdelli

Electronic Theses and Dissertations

We previously demonstrated that embryonic stem (ES) cells over-expressing tissue inhibitor of metalloproteinase-1 (TIMP-1) have increased potential to engraft and differentiate into cardiac myocytes following transplantation into the infarcted heart. However, the ability of TIMP-1 to activate endogenous stem cells and enhance their differentiation into cardiac regenerative cell types is still unknown. We postulate that TIMP-1 may additionally activate a stem cell population that enhances cardiac cell type differentiation in the infarcted myocardium. To prove this hypothesis, we isolated c-kit+ve cells from four weeks old C57BL/6 mice and cultured them in vitro in presence of ES conditioned media (ESCM), ES-TIMP-1-CM …

Chemical And Behavioral Ecology Of The Coastal Giant Salamander (Dicamptodon Tenebrosus), David Reavill

All Master's Theses

Intraspecific interactions are an important factor in shaping the population structure of terrestrial salamanders. Both physical interactions and scent-marking are vital components to the establishment of territories and influence dispersion of individuals. However, little is known about the terrestrial interactions of many salamander species, particularly that of the Coastal Giant Salamander (Dicamptodon tenebrosus). In this study, I observed the first evidence for the use chemical cues by terrestrial D. tenerosus in regards to shelter selection. I also observed the first accounts of agonistic and display behavior of terrestrial D. tenebrosus. These results suggest that terrestrial D. tenebrosus …

The Drunken Path: Discerning Women's Voices And Participation In The Informal Economy Of Illegal Manufacturing Of Prohibition Alcohol In The Historical And Archaeological Record, Kelli M. Casias

Graduate Student Theses, Dissertations, & Professional Papers

This thesis puts the Prohibition years in Anaconda and Butte, Montana, into historical, and sociocultural context to discover an engendered narrative of liquor law violators between the years 1923 and 1926 and to investigate the scope of the local informal, illegal, illicit economic systems dictating the distribution of illegal liquor during that era. The transference of the means and modes of production, as envisioned by Karl Marx, and collective social resistance serve as the theoretical frameworks for analysis and examination of three case studies. The first, Poacher Gulch is a remote mining site in western Montana, was the subject of …

Linking The Effects Of Risk Factors On Annual Calf Survival To Elk Population Dynamics In The Bitterroot Valley, Montana, Daniel R. Eacker

Graduate Student Theses, Dissertations, & Professional Papers

The recolonization of gray wolves (Canis lupus) in multiple carnivore systems has been correlated with declining recruitment of juvenile ungulates, but the importance of wolves relative to other established carnivores is uncertain. The realized effect of carnivores may depend on compensation from forage and winter weather severity, which may mediate juvenile vulnerability to predation. Also, in high predation systems, the importance of juvenile recruitment may be reduced for ungulate population dynamics. We first tested for the effects of risk factors on annual elk (Cervus elaphus) calf survival and estimated cause-specific mortality rates. Secondly, we investigated the …

Maximal Femoral Artery Blood Flow During Cycle Ergometry, Tucker W. Squires

Graduate Student Theses, Dissertations, & Professional Papers

MAXIMAL FEMORAL ARTERY BLOOD FLOW DURING CYCLE ERGOMETRY

Chairperson: Matthew Bundle Ph.D.

The delivery of oxygen to working muscle in order to support aerobic respiration has long been recognized as one of the critical elements conferring endurance performance. Oxygen is transported from the environment to the active cells by the cardiovascular system, which is classically understood to deliver progressively greater amounts of gas to support increased levels of aerobic metabolism. However, the vast majority of existing studies have used modes of exercise that activate relatively small volumes of muscle and consequently have relatively small demands for oxygen delivery. We measured …

Selective Solid Phase Extraction Of Uranium Using An Aminophosphonic Acid Functionalized Composite Material, Ranalda Tsosie

Graduate Student Theses, Dissertations, & Professional Papers

Uranium is an element of interest because it is an abundant source of concentrated energy. In 1948 the US offered money for uranium ore mined in the US, which created a mining boom in the southwest that included the Navajo Reservation. During the late 1960s the demand for uranium decreased and many mining operations shutdown and left behind a legacy of contamination. As a result many Navajo communities have numerous water sources that exceed established maximum contamination levels for uranium and other toxic metals. These contaminations are a direct result of abandoned Cold War uranium mines and mill waste sites …
