Ecology And Retribution: Blake, Tokarczuk, And Animal Rights, Kristina Isaak Powell
Ecology And Retribution: Blake, Tokarczuk, And Animal Rights, Kristina Isaak Powell
Theses and Dissertations
This thesis explores how Nobel laureate Olga Tokarczuk's 2008 novel, Drive Your Plow Over the Bones of the Dead, engages with William Blake's life and his writings on animal welfare and speaks to current conversations about multispecies justice in the environmental humanities. It argues, first, that in recognizing how this novel's protagonist, Janina, selectively reads Blake to rationalize retributive justice, readers should resist a tendency to mistake this character for Tokarczuk's ideal advocate for environmental ethics. Secondly, it asserts that legal scholars' division between retributive and restorative justice offers valuable framework for approaching both this novel and ongoing debates about …
Non-Tuberculous Mycobacterium Correlation With Geochemical Characteristics Of Soil And Basalt In Hawaii, Leeza Marie Wells
Non-Tuberculous Mycobacterium Correlation With Geochemical Characteristics Of Soil And Basalt In Hawaii, Leeza Marie Wells
Theses and Dissertations
Non-tuberculous mycobacteria (NTM) cause opportunistic lung disease though environmental exposure pathways. Among the United States, Hawaii has a significantly higher infection rate. Preliminary studies have shown certain environmental factors, such as phosphorus and other select soil geochemical characteristics, to be statistically significant to NTM occurrence. However, a model to predict NTM occurrence based on soil geochemistry had yet to be attempted. A selection of 40 NTM positive and 40 NTM negative soils from Oahu were selected for a geochemical analysis to search for possible correlations to mineralogy and elemental abundances that may promote, or inhibit, NTM growth in the environment. …
Climate Change And The Global Nutrient Overload: The Microbial Response Of Extreme Waterbodies To Environmental Change, Samuel P. Bratsman
Climate Change And The Global Nutrient Overload: The Microbial Response Of Extreme Waterbodies To Environmental Change, Samuel P. Bratsman
Theses and Dissertations
One of the defining characteristics of our current epoch—the Anthropocene—is modification of nutrient cycles. At regional to global scales, humans have fundamentally reshaped the availability of carbon, nitrogen, and phosphorus. These changes are particularly apparent in freshwater ecosystems, which receive surface and groundwater inputs of nutrients from agriculture, fossil fuel use, and wastewater. In this thesis, I investigated how the addition of nutrients affects microbial community and biogeochemistry in two extreme environments: the hypereutrophic shallow Utah Lake and nutrient-limited Arctic permafrost streams. In my first chapter, I used bioassay and dilution bioassay experiments to identify what factors control harmful algal …
Mutants, Sentinels, And Cerebro: Messages About Technology And Society In Science Fiction Films, Paige Marie Lee
Mutants, Sentinels, And Cerebro: Messages About Technology And Society In Science Fiction Films, Paige Marie Lee
Theses and Dissertations
Technology plays a significant role in society and in entertainment. People hold an ambivalent attitude about technology that is often illustrated in science fiction films. Much like myth telling stories to teach a lesson, science fiction films caution viewers of the effects of powerful technology usage in culture today. This thesis examines X-Men to show how relevant principles found in myth continue to be relevant to media consumption. Using media ecology to inform the reader about the technological environment (Mumford, 1944), this analysis of technology portrayed in X-Men shows the implications real world technology, such as radiation, weapons, and artificial …
Families In The Sky: Investigating The Population Structure Of Pinus Longaeva, Samuel Arnold Decker
Families In The Sky: Investigating The Population Structure Of Pinus Longaeva, Samuel Arnold Decker
Theses and Dissertations
In the Western United States, the Great Basin is a geographic feature that is home to a variety of unique species, including Great Basin bristlecone pine (Pinus longaeva, PILO). P. longaeva is well known for the age of some of the trees, some of which are over 4000 years old. In this study 17 microsatellite markers (simple sequence repeat, SSR) are identified and used to genotype a selection of 480 individuals spread across 24 PILO populations and 60 individuals divided equally between 2 outgroup species, Pinus aristata and Pinus flexilis. One population of PILO, HMW, shows more genetic similarity with …
Applications Of And Algorithms For Genome Assembly And Genomic Analyses With An Emphasis On Marine Teleosts, Brandon D. Pickett
Applications Of And Algorithms For Genome Assembly And Genomic Analyses With An Emphasis On Marine Teleosts, Brandon D. Pickett
Theses and Dissertations
The burgeoning frequency of genome sequencing in recent years is a testament to both the improvements in sequencing technologies and the utility of genomic analyses for biological discovery. The rapid proliferation in technological advancements and availability of complementary data types and techniques has obfuscated the optimal process of genome assembly and raised the barrier to entry to unprecedented levels. In this dissertation, we describe the genome assemblies performed for several marine teleosts and discuss the algorithms and applications required for genome assembly, including some of our specific contributions to the genome assembly and annotation space. In Chapter 1 and Chapter …
Ecological Perspectives On Study Abroad For Language Learning, Matthew Thomas Bird
Ecological Perspectives On Study Abroad For Language Learning, Matthew Thomas Bird
Theses and Dissertations
The field of study abroad for language learning has drawn extensively on related fields such as applied linguistics and psychology to conceptualize learners' experiences, which then informs how practitioners go about designing programs for those learners. Research has encouraged practitioners to increase learners' access to the target language (e.g., through speaking partners, content courses), but it has also become clear that while access might be necessary, it does not guarantee learner engagement and growth. This dissertation explores two unique conceptual frameworks for understanding language learners and presents empirical research that demonstrates the kinds of findings that these frameworks can produce. …
Dyslexia Beyond The Word: An Ecological Study Of Specific Reading Disorder, Benjamin T. Carter
Dyslexia Beyond The Word: An Ecological Study Of Specific Reading Disorder, Benjamin T. Carter
Theses and Dissertations
This dissertation discusses the effects of dyslexia on reading behavior and cognition. It does so by first outlining the overall incidence of dyslexia, providing current definitions, giving a history of scientific inquiry and discussing relevant contemporary research. Thirteen different analyses are then discussed (ten a priori and three post-hoc). Individuals with dyslexia were found to have increased fixation duration, first run dwell time, total dwell time, and refixation probability. The dyslexia group was also highly sensitive to lexical predictability. Within the reading network, the BOLD response was depressed in dyslexia during reading in the following regions: the left medial and …
Reading Fluency And Gonoodle© Brain Breaks Among Elementary-Aged Children, Hannah Jeanne Wold
Reading Fluency And Gonoodle© Brain Breaks Among Elementary-Aged Children, Hannah Jeanne Wold
Theses and Dissertations
This study examines the immediate and chronic effects of physical activity (PA) breaks on reading fluency. While many teachers recognize the value of PA for increasing engagement and focus (getting the wiggles out) in academic endeavors, these results reveal increases in academic achievement in reading fluency are also possible.This study examines 384 second and third grade students with low income backgrounds from the Rocky Mountain region. A two-way analysis of variance (ANOVA) was used to examine the effects of chronic and acute brain breaks via GoNoodle© (McQuigg, 2013) on reading fluency and physical activity (steps). Between group differences were further …
So . . . We're Going For A Walk: A Placed-Based Outdoor Art Experiential Learning Experience, Priscilla Anne Stewart
So . . . We're Going For A Walk: A Placed-Based Outdoor Art Experiential Learning Experience, Priscilla Anne Stewart
Theses and Dissertations
Schools in the United States often emphasize making children competitive in a global economy while neglecting the importance of developing citizens who are ecologically responsible. Problems of climate change, loss of biodiversity, mass extinctions and degradation of the natural environment, are often ignored. Some researchers have suggested that children lack unstructured play time in nature, have an increased amount of screen time, lack mindfulness, and are insulated from the natural world. Many children rarely have significant experience with nature's wildness. It is common for people to experience a sense of placelessness in the hyper-mobility of present times where "globalizing" agendas …
Bobcat Abundance And Habitat Selection On The Utah Test And Training Range, Kyle David Muncey
Bobcat Abundance And Habitat Selection On The Utah Test And Training Range, Kyle David Muncey
Theses and Dissertations
Remote cameras have become a popular tool for monitoring wildlife. We used remote cameras to estimate bobcat (Lynx rufus) population abundance on the Utah Test and Training Range during two sample periods between 2015 and 2017. We used two statistical methods, closed capture mark-recapture (CMR) and mark-resight Poisson log-normal (PNE), to estimate bobcat abundance within the study area. We used the maximum mean distance moved method (MMDM) to calculate the effective sample area for estimating density. Additionally, we captured bobcats and estimated home range using minimum convex polygon (MCP) and kernel density estimation (KDE) methods. Bobcat abundance on the UTTR …
An Ecological And Distributional Analysis Of Great Basin Bristlecone Pine (Pinus Longaeva), Gregory Watson Taylor
An Ecological And Distributional Analysis Of Great Basin Bristlecone Pine (Pinus Longaeva), Gregory Watson Taylor
Theses and Dissertations
Understanding the impacts of climate change is critical for improving the conservation and management of ecosystems worldwide. Ecosystems vary along a precipitation and temperature gradient, ranging from tropical jungles to arid deserts. The Great Basin is a semi-arid eco-region that is found within the western United States. Plant communities within the Great Basin range from sagebrush valleys to sub-alpine conifer forests found at high elevation areas. It is predicted that the Great Basin will experience prolonged periods of drought, more intense fires, and greater variability in average annual and monthly precipitation, all in response to changes in climate patterns. At …
Small Mammal Diversity, Rattlesnake Demographics, And Resource Utilization In The Great Basin: Implications For Management And Stable Isotope Proxies, Bryan T. Hamilton
Small Mammal Diversity, Rattlesnake Demographics, And Resource Utilization In The Great Basin: Implications For Management And Stable Isotope Proxies, Bryan T. Hamilton
Theses and Dissertations
Plant carbon isotopes were used to track assimilation of riparian resources by small mammals. Voles and shrews derived significant portions of their carbon from riparian vegetation. Deer and harvest mice were abundant in riparian habitat but assimilated little riparian vegetation indicating that the riparian corridor provided resources other than food. This is first use of stable carbon isotopes to trace riparian resources into a vertebrate community. Conifer encroachment in sagebrush ecosystems negatively affects many wildlife populations. Conifer removal is recommended across millions of hectares in the Great Basin. However the effects of conifer encroachment and conifer removal are unknown for …
Response To Drought Of A Stream Fish Assemblage In A High Elevation Stream In The Intermountain West, Richard M. Simkins
Response To Drought Of A Stream Fish Assemblage In A High Elevation Stream In The Intermountain West, Richard M. Simkins
Theses and Dissertations
One of the most influential disturbances for stream fish assemblages is large-scale declines in flow caused by periods of drought. Although stream characteristics are known to influence the response of stream fishes to drought, we asked if ecological traits of stream fishes determine, in part, their population level response to drought. To test for ecological trait-based responses to drought in a stream fish assemblage, we quantified species abundances over a period of 5 years that represented a wet to dry period. We sampled stream fishes in Yellow Creek, Wyoming, USA, a high elevation stream dependent on snow-storage for most of …
Interconnectedness, Complicity And Ambiguity: Reading With Dark Ecology, Rachel Dene Whipple
Interconnectedness, Complicity And Ambiguity: Reading With Dark Ecology, Rachel Dene Whipple
Theses and Dissertations
There are many aspects of ecological thinking. When reading texts through a lens of dark ecology, certain conflicts that arise from the imposition of human expectations on natural systems are revealed. These include interconnectedness, complicity, and ambiguities. Within a system, boundaries are contingent and transitory. Beginnings and ends are gradual, not definite. Ecological systems change over time, but it is a category error to imagine that change represents progress or to assume a teleological purpose. While there are hierarchies of power, and different roles, no species is, ecologically speaking, more advanced than another. Ecological criticism focuses on interconnectedness, complicity, and …
Population Structure, Genetic Diversity, Geographic Distribution, And Morphology Of Two Boechera (Brassicaceae) Parental Species (Boechera Thompsonii And Boechera Formosa) And Of Their Resultant Hybrid Boechera Duchesnensis, Christina Elizabeth Fox Call
Population Structure, Genetic Diversity, Geographic Distribution, And Morphology Of Two Boechera (Brassicaceae) Parental Species (Boechera Thompsonii And Boechera Formosa) And Of Their Resultant Hybrid Boechera Duchesnensis, Christina Elizabeth Fox Call
Theses and Dissertations
Background: Over the relatively short period of its evolutionary history, Boechera (Brassicaceae) has undergone rapid radiation that has produced 70+ morphologically distinct, sexual diploids. However, reproductive isolation has moved more slowly than morphological divergence in this group and the diploids appear to hybridize frequently where they coexist. Boechera duchesnensis appears to be the result of hybridization between its putative parents Boechera thompsonii and Boechera formosa. Objectives: The objectives of this study are to (i) analyze and document genetic diversity patterns in the population structure, - including allelic and heterozygosity frequencies - of B. thompsonii and B. formosa …
High Salinity Stabilizes Bacterial Community Composition And Activity Through Time, Tylan Wayne Magnusson
High Salinity Stabilizes Bacterial Community Composition And Activity Through Time, Tylan Wayne Magnusson
Theses and Dissertations
Dormancy is a plausible strategy for bacteria to overcome the effects of temporal fluctuations in resources or stresses and await more “optimal” conditions to resume metabolic activity and growth. Seasonal changes in environmental conditions force microbes to adjust their metabolic activity accordingly, and community composition drastically shifts. In extreme environments, however, the overriding effects of a constant stress may constrain the need or benefit of bacteria entering dormancy. In hypersaline lakes, high metabolic activity is required to maintain adaptations that permit survival. Sampling from six lakes on a salinity gradient (0.05% – 30.3%), we measured seasonal fluctuations in bacterial dormancy …
A Maoli-Based Art Education: Ku'u Mau Kuamo'o 'Ōlelo, Raquel Malia Andrus
A Maoli-Based Art Education: Ku'u Mau Kuamo'o 'Ōlelo, Raquel Malia Andrus
Theses and Dissertations
Leaders in K-12 education in Hawai'i are increasingly advocating for and utilizing the culture and knowledge of the kānaka Maoli, the native people of these islands, as a context for learning in a variety of curricular disciplines and approaches (Benham & Heck, 1998; Kani'iaupuni, Ledward & Jensen, 2010; Kana'iaupuni & Malone, 2006; Kahakalau, 2004; Meyer, 2004). To expand upon this trend, this thesis uses a combination of autoethnographic and critical indigenous methodologies to present a personal narrative that looks specifically at approaching art education from a Maoli perspective. Through extensive participant/observer reflections, two place-based and culture-based art education experiences are …
A Survey Of Invasive Exotic Ants Found On Hawaiian Islands: Spatial Distributions And Patterns Of Association, Camie Frandsen Martin
A Survey Of Invasive Exotic Ants Found On Hawaiian Islands: Spatial Distributions And Patterns Of Association, Camie Frandsen Martin
Theses and Dissertations
An intensive sampling of all ant species encountered on 6 Hawaiian Islands: Big Island, Maui, Oahu, Kauai, Molokai, and Lanai took place between 1988 and 1996. Species presence and absence was recorded at each site. Using remote sensing, variables were added insitu and used throughout my analysis. Species accumulation curves suggest that sampling was comprehensive. There is a significant trend between island area and species richness which validates the Theory of Island Biogeography for invasive species. Islands were found to be significantly nested by area, order, and tourism. Cluster analysis shows a link between elevation, land-use and island, and species …
Stable Isotope Diet Reconstruction Of Feral Horses (Equus Caballas) On The Sheldon National Wildlife Refuge, Nevada, Usa, Megan Kathleen Nordquist
Stable Isotope Diet Reconstruction Of Feral Horses (Equus Caballas) On The Sheldon National Wildlife Refuge, Nevada, Usa, Megan Kathleen Nordquist
Theses and Dissertations
Feral horse management has become a subject of significant controversy in the United States. This is because of differing opinions and minimal recent empirical data on feral horses. In recent years, numbers of feral horses have increased due to governmental horse removal restrictions (specifically the Wild Horse and Burro act of 1971). With increasing numbers of feral horses on rangelands, land managers are challenged with identifying the appropriate course of action for satisfying groups with differing opinions. The purpose of this study is to characterize diet consumption through the use of stable isotope dietary analysis (δ15N and δ13C). We did …
Changes In Life History Within An Individual's Lifetime, Eric J. Billman
Changes In Life History Within An Individual's Lifetime, Eric J. Billman
Theses and Dissertations
A central goal of life history theory is to understand the selective factors that generate the diversity of reproductive patterns observed in nature. Within lifetime changes in reproductive investment will determine an organism's fitness; however, this area of life history theory has received less attention than comparisons among population that characterize life history traits as a single population mean. Reproductive allocation can be affected by multiple cues; the integration of these cues across an organism's lifetime generates the diversity in life history strategies observed in nature. Life history studies should examine the interacting effects of multiple cues on life history …
Usage And Development Of Molecular Markers For Investigation Of The Population And Ecological Genetics Of Bromus Tectorum L., Keith R. Merrill
Usage And Development Of Molecular Markers For Investigation Of The Population And Ecological Genetics Of Bromus Tectorum L., Keith R. Merrill
Theses and Dissertations
This thesis includes two studies: The first examined patterns of neutral genetic diversity within Bromus tectorum L. across the IMW region, and uses patterns of microsatellite (SSR) genotype distribution to make inferences about the respective roles of adaptively significant genetic variation, adaptive phenotypic plasticity, and facultative outcrossing in the ongoing invasion and recent range expansion of B. tectorum. It has been previously demonstrated that, due to extremely low outcrossing rates, it is possible to characterize individual genotypes of this species using four SSR loci. We sampled 20 individuals from each of 96 B. tectorum populations (classified by region and …
Sleep, Bmi, And Work-Family Conflict: A Gender Comparison Of U.S. Workers, Blake Lee Jones
Sleep, Bmi, And Work-Family Conflict: A Gender Comparison Of U.S. Workers, Blake Lee Jones
Theses and Dissertations
This study used structural equation modeling (SEM) to examine how sleep problems, Body Mass Index (BMI), and poverty were related to several work, personal, and family variables in a sample of married male and female workers in the United States. The data for this study came from the National Study of the Changing Workforce (NSCW) 2008. This large, nationally representative dataset provided a resource for examining potential gender differences in variables that have been linked to sleep problems and increases in BMI, as well as how each of these variables relate to several work, personal, and family life outcomes, including …
Multidisciplinary Assessment And Documentation Of Past And Present Human Impacts On The Neotropical Forests Of Petén, Guatemala, Christopher Stephen Balzotti
Multidisciplinary Assessment And Documentation Of Past And Present Human Impacts On The Neotropical Forests Of Petén, Guatemala, Christopher Stephen Balzotti
Theses and Dissertations
Tropical forests provide important habitat for a tremendous diversity of plant and animal species. However, limitations in measuring and monitoring the structure and function of tropical forests has caused these systems to remain poorly understood. Remote-sensing technology has provided a powerful tool for quantification of structural patterns and associating these with resource use. Satellite and aerial platforms can be used to collect remotely sensed images of tropical forests that can be applied to ecological research and management. Chapter 1 of this article highlights the resources available for tropical forest remote sensing and presents a case-study that demonstrates its application to …
Diversity And Abundance Of The Dark Kangaroo Mouse, Microdipodops Megacephalus, In Communities Of Nocturnal Granivorous Rodents In Western North America, Ashley Sagers Haug
Diversity And Abundance Of The Dark Kangaroo Mouse, Microdipodops Megacephalus, In Communities Of Nocturnal Granivorous Rodents In Western North America, Ashley Sagers Haug
Theses and Dissertations
The dark kangaroo mouse, Microdipodops megacephalus, is a sensitive species in the Great Basin Desert. This thesis explores the structure of desert rodent communities of the Great Basin to better understand M. megacephalus' place in the community and the conditions that promote large and stable populations. To determine community structure, I used nestedness analysis to evaluate 99 communities of nocturnal granivorous rodents. I found that the community structure was non-random, indicating the existence of assembly rules and ecological constraints. I also found that M. megacephalus was the second most vulnerable species in the community. To explore the correlation …
Taxonomy And Applied Biogeography Of Mongolian Stoneflies (Insecta: Plecoptera), Sarah Walker Judson
Taxonomy And Applied Biogeography Of Mongolian Stoneflies (Insecta: Plecoptera), Sarah Walker Judson
Theses and Dissertations
Since the early 1900s, efforts have been made to catalogue the stoneflies of Mongolia. Taxonomic work from 1960 to 1980 greatly expanded basic lists of stoneflies in Mongolia, but no comprehensive survey or synthesis of this dispersed literature has been completed. In conjunction with a modern survey of the aquatic insects of Mongolia, we collected Plecoptera on a series of expeditions to the Selenge (north) and Altai (west) regions of Mongolia. A total of 48 species distributed in 24 genera and 8 families were documented, including 3 of the 5 Mongolian endemics, 2 new species records for Mongolia, and 1 …
Parental Factors As A Moderator Of The Co-Occurrence Of Substance Use And Depression In Hispanic Adolescents, Rebecca Shoff
Parental Factors As A Moderator Of The Co-Occurrence Of Substance Use And Depression In Hispanic Adolescents, Rebecca Shoff
Theses and Dissertations
The purpose of this study was to evaluate the relationship between parenting factors and Hispanic adolescent substance use and depression. Specifically, the study examined the relationship between parental support, parental knowledge, and parental psychological control among Hispanic adolescents' use of alcohol, tobacco, marijuana, hard drugs and depressive symptoms. The sample included 839 Hispanic (primarily Mexican) 9th – 12th graders from west Texas area school districts who were given a self-reported survey to assess parental behaviors, substance use, and adolescent depression. Using structural equation modeling (SEM), findings indicated that higher levels of maternal support were related to lower levels of depressive …
The Ecological Importance Of Extrinsic And Intrinsic Drivers Of Animal Movement, Josh Earl Rasmussen
The Ecological Importance Of Extrinsic And Intrinsic Drivers Of Animal Movement, Josh Earl Rasmussen
Theses and Dissertations
The movement of individuals is foundational to many ecological processes. For example, the movement of an organism from one place to another alters population density at both sites and has potential for affecting the genetic dynamics within the new population. Individual movement events may be in synchrony with overall trends in populations, e.g. spawning migrations, or may be atypical (asynchronous). This latter movement type can affect population and metapopulation dynamics, depending on its prevalence within a population. Nevertheless, given the complexity of interactions, the causative factors of movement are understood vaguely, much less for aquatic organisms. Drivers of movement are …
Co-Occurrence With A Congeneric Species Predicts Life History And Morphological Diversification In The Mexican Livebearing Fish Poelicopsis Baenschi, Laura E. Scott
Theses and Dissertations
Understanding why some species coexist and others do not remains one of the fundamental challenges of ecology. While several lines of evidence suggest that closely related species are unlikely to occupy the same habitat because of competitive exclusion, there are many cases where closely related species do co-occur. Research comparing sympatric and allopatric populations of co-occurring species provides a framework to understand the role of phenotypic diversification in species coexistence. In this study I focus on the livebearing fish Poeciliopsis baenschi and ask if differences in phenotypic traits among populations can be explained by the presence or absence of the …
A Comparison Of Two Common Classification Procedures For Economical Urban Land Cover Mapping Using Naip Imagery, Kent Lowell Simons
A Comparison Of Two Common Classification Procedures For Economical Urban Land Cover Mapping Using Naip Imagery, Kent Lowell Simons
Theses and Dissertations
Detailed urban land cover maps are increasingly useful and important applications of remote sensing. Municipal agencies and others use land cover maps and data for numerous critical local planning and monitoring functions and for urban geographical research studies. Because of this, there is a demand for accurate urban land cover maps that can be produced quickly and economically. The availability of very high resolution multispectral imagery is an important factor in enabling such production, as the judicious selection of source imagery has a large impact on the resulting map products. Likewise, the implementation of appropriate digital image processing methods is …
