Population Dynamics Of The Columbia Spotted Frog (Rana Luteiventris): Inference From Long-Term Demography, Rebecca Marie Wahl Mccaffery

Graduate Student Theses, Dissertations, & Professional Papers

Worldwide extinctions of amphibians are at the forefront of the biodiversity crisis, with climate change figuring prominently as a potential driver of continued amphibian decline. Changes in both the mean and variability of climate conditions may affect amphibian populations in complex, unpredictable ways. However, few studies have evaluated effects of climate change on individual vital rates and subsequent population dynamics of amphibians. I investigated the population dynamics of a high elevation population of the Columbia spotted frog (Rana luteiventris) in relation to climate variation over a ten-year period.

I documented an increase in survival and breeding probability as severity of …

Are Black Bears Declining In Montana? Inference From Multiple Data Sources In The Face Of Uncertainty, Julie Ann Beston

Graduate Student Theses, Dissertations, & Professional Papers

Carnivores are managed both to maintain populations and reduce conflict with humans, but data-based decision-making is difficult due to the expense of data collection. When new fieldwork is impossible, we can benefit from available data in assessing populations. I used demographic and harvest data to assess the population status of black bears (Ursus americanus) in Montana.

I conducted a hierarchical Bayesian meta-analysis of black bear demographic studies to evaluate geographic structuring and estimate vital rates and population growth rate. Adult survival is higher in the west than the east, but the reverse is true for fecundity. The mean …

Biological Control: Effects Of Tyria Jacobaeae On The Population Dynamics Of Senecio Jacobaea In Northwest Montana, Kimberly Kay Crider

Graduate Student Theses, Dissertations, & Professional Papers

Biological control, using introduced, specialist insects is a common strategy for controlling plant invasions. However, the efficacy of biological control agents in controlling their host plants is rarely quantified population level. I quantified the impact of a specialist biological control agent, the cinnabar moth (Tyria jacobaeae) on its host plant, tansy ragwort (Senecio jacobaea) in northwest Montana. Cinnabar moth damage and its effects on important plant vital rates were tested with and without specialist herbivores. The presence of moth larvae corresponded to a reduction in population growth rates to less than one, compared to herbivore-free controls, indicating the potential for …

Causes And Consequences Of Prolonged Dormancy: Why Stay Belowground?, Jennifer R. Gremer

Graduate Student Theses, Dissertations, & Professional Papers

Prolonged dormancy is a stage in which mature plants fail to resprout during the growing season and instead remain alive belowground. Though it is relatively common, the causes and consequences of this intriguing stage have remained elusive. In this dissertation, I investigate the causes and consequences of prolonged dormancy in a long lived perennial herb, Astragalus scaphoides.

First, I use a combination of demography and ecophysiology to study the proximate mechanisms associated with prolonged dormancy. Analysis of a long-term demographic dataset indicates that both endogenous factors (e.g. age, condition, and history) and exogenous factors (e.g. climate and spatial variation) are …

Msculine Identity And The Education And Parental Involvement Of African American Teen Fathers, Milissa Mcclaire Gary

College of Education Theses and Dissertations

African American males are more likely to become teenage fathers than their white counterparts, and the risk is increased for those living in low-income communities. This qualitative work is a case study exploring the life experiences of one African American teen father from a working class urban area. The research investigates the ways in which conceptions of masculinity impact the identity formation and parental engagement of African American teen fathers. It also explores the ways in which they may seek to fulfill multiple, and often competing, social roles including father, student, and young Black man in society. The findings acknowledge …

Religious Experiences In New England, Douglas L. Winiarski

Religious Studies Faculty Publications

This chapter examines the shifting language of conversion in New England Congregationalism - the bastion of Puritan culture in North America - from the period of settlement in the 1630s to the eve of the Civil War. Evidence is drawn from a database of more than a thousand church-admission narratives from nearly three dozen communities scattered across Massachusetts, Connecticut, and New Hampshire. Throughout this period, most Congregational ministers remained committed to a Calvinist theology that emphasized innate human depravity, unconditional election, limited atonement, and irresistible grace. Yet the importance of conversion - the sacred calculus through which God winnowed saints …

Pregnancy Intentions Among Women Who Do Not Try: Focusing On Women Who Are Okay Either Way, Julia Mcquillan, Arthur L. Greil, Karina M. Shreffler

Department of Sociology: Faculty Publications

Objectives: Are women who are intentional about pregnancy (trying to or trying not to get pregnant) systematically different from women who are “okay either way” about getting pregnant?
Methods. We use a currently sexually active subsample (n = 3,771) of the National Survey of Fertility Barriers, a random digit dialing telephone survey of reproductive-aged women (ages 25–45) in the United States. We compare women who are trying to, trying not to, or okay either way about getting pregnant on attitudes, social pressures, life course and status characteristics using bivariate analyses (chi-square tests for categorical and ANOVA tests for continuous variables). …

Genetic Characterization, Ginsenoside Analysis And Micropropagation Of American Ginseng (Panax Quinquefolius L.), Samuel G. Obae

Graduate Theses, Dissertations, and Problem Reports (ETD)

American ginseng (Panax quinquefolius L.), is an economically important medicinal plant native to eastern deciduous forests of North America. Like many other medicinal plants worldwide, P. quinquefolius is mainly collected from the wild. And because of its growing demand, abundance of wild populations is threatened with over harvesting. In West Virginia, P. quinquefolius is available both in cultivation and in the wild. Even though P. quinquefolius occurs in all 55 counties in West Virginia, patterns of its harvesting and cultivation vary across the state. As described in chapter 2, the genetic diversity and population structure of P. quinquefolius under two …

Dammed And The Damned: Draining The Bucket Dry, Carla Steiger

Browse all Theses and Dissertations

This thesis investigates how people displaced from the construction of large dams in seek environmental justice. I studied the importance of regime type, the creation of protest groups and the formation of alliances with national, international organizations, and the media. In a comparison between protest movements against the Three Gorges Dam in China and the Sardar Sarovar Dam in India, displaced populations suffered from loss of community, livelihood, and health and were victimized by corrupt actors that supported the dams. The rapid economic development of these two countries emerged as a major point of comparison between the two. Regime type …

Students' Perceptions Of Collaboration Tools In A Higher Education Online Collaborative Learning Environment, Kirk Henry

Electronic Theses and Dissertations

Higher education funding and student behavior has been changing rapidly (Dervarics,2008). Because of this, there has been an increased focus on the use of alternative tools for course delivery. One of the emerging areas of focus has been an increased interest in the use of communication and information technologies (Curtis & Lawson, 2001). Currently, there are a wide variety of flexible delivery methods that have been used as well as their associated tools. Naturally, questions have been raised about the efficacy of these tools on the quality of student-student, student-teacher, and student-content interaction (Curtis & Lawson, 2001). Interaction and Collaboration …

A Model Of Flow And Play In Game-Based Learning The Impact Of Game Characteristics, Player Traits, And Player States, Davin Pavlas

Electronic Theses and Dissertations

In this dissertation, the relationship between flow state, serious games, and learning was examined. Serious games, which are games that convey something other than enjoyment (e.g., learning), are increasingly popular platforms for research, training, and advertisement. The elements that make serious games useful to researchers, trainers, and practitioners are closely linked to those that make up the positive psychology construct of flow state. Flow state describes an optimum experience that is encountered when a variety of factors are met, and is characterized by high focus, engagement, motivation, and immersion. While flow state is often discussed in the serious games literature, …

Exploring The Endocrine Profile Of A Geriatric Female Chimpanzee (Pan Troglodytes), Christina T. Cloutier

Electronic Theses and Dissertations 2010 - 2019

In light of exceptionally delayed reproductive senescence exhibited by a 64 year old female chimpanzee (Pan troglodytes) housed in Florida, endocrinal analyses meant to determine the state of her current reproductive viability were conducted. Urine was collected from the study subject for a period of 88 days spaced within an interim of roughly 6 months and the specimens were sent to the Hominoid Reproductive Ecology Laboratory for assessment. Additional data was collected from three control females in order to provide a basis of comparison against the hormonal markers present in the geriatric study animal. Results indicate that the geriatric female …

Florida Middle Grades Pupil Progression Policies, Mary A. Murray

Electronic Theses and Dissertations 2010 - 2019

Florida H.B. 7087 (2006a), otherwise known as A++legislation, was created and adopted as a means to increase the rigor and relevance of a public school education, specifically at the middle school and high school levels. The anticipated result of the implementation of this bill was to better prepare middle school students for high school and thereby increase high school student performance and decrease the dropout rate. However, in increasing the promotion standards for middle grade students, interpretation and implementation have created additional barriers to grade level advancement. As a result, the possibility now exists for more students and especially those …

Implementation And Evaluation Of The Jesus Loves Jeans Initiative To Evangelize And Retain Youth For The Houston International Seventh-Day Adventist Church, Kendall Turcios

Doctor of Ministry Projects

The Topic

The Houston International Seventh-day Adventist (SDA) Church has had significant challenges baptizing and retaining its youth. In the last five years, only a few youth have been baptized and nearly 50% no longer attend church. A primary contributing factor seems to be the lack of training to develop genuine biblical discipleship in the youth and young adults. Eims (1978) describes the process of discipleship as ―[taking a] person from the time of his conversion and helping him become a solid, dedicated, committed, fruitful, mature disciple who could in time repeat that process in the life of another‖ (p. …

Population Genetics And Systematics Of A Species-Rich Clade Of Neotropical Reef Fishes, The Tubeblenny Genus Acanthemblemaria, Ron Israel Eytan

LSU Doctoral Dissertations

Neotropical coral reef fish communities are species-poor compared to those of the Indo-West Pacific. An exception to that pattern is the blenny clade Chaenopsidae, one of only three coral reef fish families endemic to the Neotropics. Within the chaenopsids, the genus Acanthemblemaria is the most species-rich. To understand the origin and maintenance of genetic and species diversity in these fishes, I characterized the population genetics for two Acanthemblemaria species, reconstructed the phylogeny of the group, and identified suites of correlated morphological characters responsible for the distinctive skull morphology of these fishes. By combining nuclear and mitochondrial sequence data I was …

Environmental Barriers Contributing To Dental Caries Among Diverse And Underserved Children: Meeting The Challenge In The United States And Iowa, Venus Hernandez

Graduate Research Papers

The purpose of this literature review of secondary data is to 1) Identify environmental factors such as oral health education, water fluoridation and sealant programs, access to dental insurance, and dental health workforce issues, that may contribute to poor oral health, and 2) Provide recommendations to reduce these barriers that are linked with oral health disparities among children in the United States and Iowa. This literature review concludes that there is a need to consider comprehensive, multiple approaches to address family and community determinants of oral health. Some of these strategies include simultaneous efforts, such as increasing the number of …

Evidence For Recent Population Bottlenecks In Northern Spotted Owls (Strix Occidentalis Caurina), W. Chris Funk, Eric D. Forsman, Matthew Johnson, Thomas D. Mullins, Susan M. Haig

United States Geological Survey: Staff Publications

The northern spotted owl (Strix occidentalis caurina) is one of the most controversial threatened subspecies ever listed under the US Endangered Species Act. Despite protection of its remaining forest habitat, recent field studies show continued declines of northern spotted owls. One potential threat to northern spotted owls which has not yet been shown is loss of genetic variation from population bottlenecks. Bottlenecks can increase the probability of mating among related individuals, potentially causing inbreeding depression, and can decrease adaptive potential. Here we report evidence for recent bottlenecks in northern spotted owls using a large genetic dataset (352 individuals …

Gamma Ray Burst Redshift Catalog And Applications, Limin Xiao

LSU Doctoral Dissertations

The measurement of redshifts for gamma-ray bursts (GRBs) is an important issue for the study of the high redshift universe and cosmology. We developed a program to estimate the redshifts for GRBs from the original light curves and spectra, aiming to get redshifts for bursts without spectroscopic or photometric redshifts. We derive the luminosity indicators from the light curves and spectra of each burst, including the lag time between low and high photon energy light curves, the variability of the light curve, the peak energy of the spectrum, the number of peaks in the light curve, and the minimum rise …

A Qualitative Study Of Bariatric Patients And Their Social And Emotional Experiences After Surgery, Denise Hall

Walden Dissertations and Doctoral Studies

Previous research has indicated that the majority of individuals who undergo bariatric surgery have histories of psychological disorders. Only a paucity of research has examined the social and emotional effects of bariatric surgery on patients. Using Kelly's personal construct theory as the conceptual framework, this phenomenological study was designed to gain more insight into how this life-altering bariatric surgery transforms patients socially and emotionally. Fifteen participants who had undergone bariatric surgery in the past 10 years were interviewed for the study. The interviews were transcribed and coded. Similar themes found within the interviews were identified as the primary themes of …

The End Of Farming In The “Northern Periphery” Of The Southwest, James R. Allison

Faculty Publications

Prehispanic farmers belonging to the Virgin and Fremont traditions once occupied most of Utah and adjacent parts of Arizona and Nevada. Through much of the twentieth century, these areas were called the "Northern Periphery'' of the Southwest, but in recent decades, both Fremont and Virgin have often been left out of syntheses of southwestern archaeology-even though they clearly had strong connections to the Southwest and represented, respectively, the northernmost and westernmost extensions of maize-based horticulture in western North America. This exclusion results from a combination of factors, the most important of which are geography and the territorial behavior of some …

Loss Of Foundation Species Increases Population Growth Of Exotic Forbs In Sagebrush Steppe, J S. Prevey, M J. Germino, Nancy J. Huntly

Biology Faculty Publications

The invasion and spread of exotic plants following land disturbance threatens semiarid ecosystems. In sagebrush steppe, soil water is scarce and is partitioned between deeprooted perennial shrubs and shallower-rooted native forbs and grasses. Disturbances commonly remove shrubs, leaving grass-dominated communities, and may allow for the exploitation of water resources by the many species of invasive, tap-rooted forbs that are increasingly successful in this habitat. We hypothesized that exotic forb populations would benefit from increased soil water made available by removal of sagebrush, a foundation species capable of deep-rooting, in semiarid shrub-steppe ecosystems. To test this hypothesis, we used periodic matrix …
