Identifying Environmental Factors Influencing Golden Eagle Presence And Reproductive Success, Ross H. Crandall
Identifying Environmental Factors Influencing Golden Eagle Presence And Reproductive Success, Ross H. Crandall
Graduate Student Theses, Dissertations, & Professional Papers
Declining populations of plant and animal species is a major concern threatening global biodiversity. If we want to conserve threatened species, we must understand the requirements of the species. Recent data suggests Golden Eagle populations in the Western United States are declining. Future threats from expanded energy development, habitat loss and climate change are also a concern. Apparent declines and perceived threats have caused management agencies to classify the Golden Eagle as a species of concern requiring the creation of conservation plans. Yet, an effective conservation plan is dependent on information that is currently lacking. To address this lack of …
Differentiation-Induced Changes In Antioxidant Capacity And Antioxidant Response In Sh-Sy5y Cells: Role Of Nrf2, Akua Afriyie Karikari
Differentiation-Induced Changes In Antioxidant Capacity And Antioxidant Response In Sh-Sy5y Cells: Role Of Nrf2, Akua Afriyie Karikari
Graduate Student Theses, Dissertations, & Professional Papers
Organisms are exposed to reactive oxygen species from internal metabolism and environmental toxicant exposure, which have been linked to the initiation and progression of many neuronal diseases such as Alzheimer’s and Parkinson’s diseases. Exposure to reactive oxygen species are counterbalanced by antioxidant defense systems such as the Nrf2-ARE pathway, the primary regulator of endogenous antioxidant response. Whereas neuronal cells are post-mitotic and are particularly susceptible to oxidative stress because of high oxygen consumption, astrocytes are mitotic and rely more on glycolytic metabolism. In this study, the difference in antioxidant response and capacity in mitotic and post-mitotic cells were investigated using …
Whole-Nature: Integrating Science And Eco-Phenomenology, Bartholomew Patrick Walsh
Whole-Nature: Integrating Science And Eco-Phenomenology, Bartholomew Patrick Walsh
Graduate Student Theses, Dissertations, & Professional Papers
A review of the literature in environmental philosophy reveals a certain tension between what we might call science-based and experience-based approaches to environmental ethics. The main trend of thought here follows seminal figures like Aldo Leopold and Holmes Rolston III by generally looking to the sciences for disclosing value in nature, particularly ecology and evolutionary biology. However others, such as David Abram and Jack Turner, worry that scientifically disclosed nature is in itself too distancing, objectifying, and abstract to engender any real care for nature and instead emphasize direct, embodied experience with actual wild places, hence the label “eco-phenomenology.” The …
Effects Of Disturbance On Tree Community Dynamics In Whitebark Pine Ecosystems, Jeremy Travis Amberson
Effects Of Disturbance On Tree Community Dynamics In Whitebark Pine Ecosystems, Jeremy Travis Amberson
Graduate Student Theses, Dissertations, & Professional Papers
Whitebark pine (Pinus albicaulis), a keystone species of high-elevation ecosystems of western North America, is warranted for listing under the Endangered Species Act due to the combined threats of fire exclusion, white pine blister rust (Cronartium ribicola), and increased pressure from insects due to climate warming. Despite widespread knowledge of the potential causes of the tree’s decline, there is limited understanding of its ecology, including successional dynamics in forests disturbed by white pine blister rust and mountain pine beetle. Specifically, there is a need for more information on successional replacement by subalpine fir and whitebark seedling regeneration dynamics. I assessed …
Effects Of Local And Landscape Processes On Animal Distribution And Abundance, Aaron David Flesch
Effects Of Local And Landscape Processes On Animal Distribution And Abundance, Aaron David Flesch
Graduate Student Theses, Dissertations, & Professional Papers
Investigations of processes that drive animal distribution and abundance are often approached at one of two different scales and therefore focus on different processes. At local scales, animals are thought to select home ranges or territory patches in an ideal manner by occupying them in order of their fitness potential, but a variety of processes can decouple choices from their fitness consequences and create non-ideal patterns of distribution. At landscape scales, the spatial arrangement of habitat patches and their size and isolation are thought to influence distribution patterns because extinction probability declines with increasing patch area and colonization probability declines …
Opportunities And Constraints To Community Forest User Groups Participating In Redd+ Payment Programs In Nepal, Alexander Cuthbert Smith
Opportunities And Constraints To Community Forest User Groups Participating In Redd+ Payment Programs In Nepal, Alexander Cuthbert Smith
Graduate Student Theses, Dissertations, & Professional Papers
In response to global concern for the consequences of climate change, the United Nations’ Reducing Emissions from Deforestation and Forest Degradation (REDD+) program was developed to support greenhouse gas emission reduction and carbon sequestration in developing countries. While still being developed around the world, in Nepal a REDD+ pilot project is being conducted with the involvement of the Nepali government’s Department of Forestry (DoF) and its community forestry program. The pilot project is called “REDD+ in Community Managed Forests in Nepal” (RCMFN). The commitment of Nepal’s government to carry out this project makes it an ideal location to study carbon …

Imagining Boundaries: (Post) Humanist Understandings And Ecological Ethics In The Fiction Of Margaret Atwood, Megan Kathleen Telligman
Imagining Boundaries: (Post) Humanist Understandings And Ecological Ethics In The Fiction Of Margaret Atwood, Megan Kathleen Telligman
Graduate Student Theses, Dissertations, & Professional Papers
Atwood’s concern for the environment has spanned nearly the entirety of her career, informing her fears about the future and providing the grounding for her speculative fiction. In Atwood’s understanding, ecological ruin stems from human estrangement from the natural environment, an estrangement fortified by capitalism and consumerism in contemporary societies. Instead, she strives to situate the creative, imaginative human species within a larger natural order that inspires ethical treatment of the more-than-human world. Atwood attempts to provide us with a model of interconnection and respect for nature that we must imagine if we desire to avoid the apocalyptic future she …
Getting On Nicely In The Dark: The Perils And Rewards Of Annotating Ulysses, Barbara Nelson
Getting On Nicely In The Dark: The Perils And Rewards Of Annotating Ulysses, Barbara Nelson
Graduate Student Theses, Dissertations, & Professional Papers
The problem of how to provide useful contextual and extra-textual information to readers of Ulysses has vexed Joyceans for years. The debate has generated lively and opinionated discussions in print and at Joyce meetings, forums and listservs. On one side are scholars who argue for scaled-down annotations that present only basic information as simply as possible, minimizing the amount of interpretation involved. On the other side are the actual first-time readers, struggling to make sense of Joyce’s complex, highly allusive text, and willing to accept help wherever it may be found. The work of annotation is both complicated and enriched …

Performing At The Block: Scripting Early Modern Executions, Jennifer Lillian Lodine-Chaffey
Performing At The Block: Scripting Early Modern Executions, Jennifer Lillian Lodine-Chaffey
Graduate Student Theses, Dissertations, & Professional Papers
This thesis explores the executions of noble men and women in Tudor and early Jacobean England and the theatrical representations of executions that mirrored real life spectacles of deadly punishment. Historical scaffold confessions followed a formulaic pattern and condemned traitors performed their final moments before a crowd of witnesses with the power to judge the quality of the actor’s deportment, costuming and words. As a public stage, the scaffold allowed the traitor a chance to assert and define his or her own individuality in the face of death and formulaic requirements, which I outline in the first chapter. Dramatic representations …
Narrative Reflection And Anatomical Introspection In Thomas Carlyle's Sartor Resartus And Herman Melville's Moby Dick, Torey Elizabeth Davie
Narrative Reflection And Anatomical Introspection In Thomas Carlyle's Sartor Resartus And Herman Melville's Moby Dick, Torey Elizabeth Davie
Graduate Student Theses, Dissertations, & Professional Papers
Thomas Carlyle’s Sartor Resartus (1831) and Herman Melville’s Moby Dick or, the Whale (1851) combine the novel and the anatomy, creating a plot as well as a reflection on the human condition. The result of this combination produces a narrator whose single-minded focus on an object both propels events forward while at the same time stalling the progress of a traditional plot. The aspects of the text that connect to the novel, such as character and plot, offer a reflection of the effect truth and society have on character. Aspects that connect to the anatomy, such as the exhaustive knowledge …
Queer Panic In Native American Literature, Theodore Cecil Decelles
Queer Panic In Native American Literature, Theodore Cecil Decelles
Graduate Student Theses, Dissertations, & Professional Papers
Indigenous American sexual minorities and alternatively gendered voices went underground due to Eurowestern sexual colonization from the time of the conquistador invasions of the early 16th century to the political campaigns of cultural homogenization of the mid-20th century. A cultural distortion still exists in the postcolonial era. In the past many North American indigenous nations had culturally specific sexualities and genders that reflected the cultural heterogeneity of the Americas. Today cultural assimilation negatively affects queer Native Americans, and culturally imported attitudes of homophobia are reflected in Native American literature. An interdisciplinary approach must be used to study the cultural distortion …

Archaeology Database Management: A Case Study In The Solution Of Incompatibility Issues Between Different Archaeological Databases, Nathaniel Scherr
Archaeology Database Management: A Case Study In The Solution Of Incompatibility Issues Between Different Archaeological Databases, Nathaniel Scherr
Graduate Student Theses, Dissertations, & Professional Papers
Archaeologists tend to use computerized databases to record data recovered from excavations. These databases contain large collections of information that can aid archaeologists in making educated decisions, interpretations, and test hypotheses from the recovered data. As time passed, databases became bigger and varied in the information that can be stored. As a result, more data could be recorded from the field that in turn can be used to ask more complicated questions of archaeological remains. However, the use of computerized archaeological databases does not come without its own problems. For example, since each archaeological project can be governed by different …
Brucellosis Transmission Between Wildlife And Livestock In The Greater Yellowstone Ecosystem: Inferences From Dna Genotyping, Michael Patrick O'Brien
Brucellosis Transmission Between Wildlife And Livestock In The Greater Yellowstone Ecosystem: Inferences From Dna Genotyping, Michael Patrick O'Brien
Graduate Student Theses, Dissertations, & Professional Papers
Brucellosis transmission between wildlife species and cattle in the greater Yellowstone ecosystem has been difficult to assess because the causative agent Brucella abortus bacteria is extremely difficult to isolate for DNA genotyping. We examined transmission of B. abortus between bison, elk, and cattle using nine variable-number tandem repeat (VNTR) markers on DNA from 98 isolates of B. abortus recovered from elk, bison, and cattle. All specimens were from geographically distinct populations in Idaho, Montana, and Wyoming. A haplotype network consisting of 54 individual haplogroups was generated from these isolates using Network v4.61. Network assessments of genetic relatedness among Brucella isolates …
Pryor Mountain Mustangs: On The Range Or On The Bring?, Monica Gokey
Pryor Mountain Mustangs: On The Range Or On The Bring?, Monica Gokey
Graduate Student Theses, Dissertations, & Professional Papers
At the Pryor Mountain Wild Horse Range straddling the Montana-Wyoming border, the fate of a herd of mustangs rests with the Bureau of Land Management and local horse conservationists. Nationally, the two sides are generally pitted against each other in the ugly world of horse politics. But in the Pryors, advocates and government have forged a tenuous partnership. Both sides want to see healthy horses on healthy range. And there could hardly be a better herd to benefit from such a truce. The Pryor Mountain mustangs have a unique genetic heritage at stake. The horses are some of the last …
The Ecology Of Tick-Borne Relapsing Fever In Western North America, Tammi Lynne Johnson
The Ecology Of Tick-Borne Relapsing Fever In Western North America, Tammi Lynne Johnson
Graduate Student Theses, Dissertations, & Professional Papers
In North America the primary cause of tick-borne relapsing fever (TBRF) is the spirochete Borrelia hermsii that is vectored by the tick Ornithodoros hermsi. Ecological investigations were combined with mathematical modeling and genetics to gain a clearer understanding of the interactions and mechanisms responsible for disease maintenance, distribution, and genetic diversity. The objectives of this research were to: 1) identify mammals associated with B. hermsii and O. hermsi by determining active infection and antibody presence, 2) develop a deterministic model to ascertain ecological and epidemiological parameters essential for disease persistence, 3) resolve the phylogeographic structure of B. hermsii and …
The Effect Of Spillover Onto Ionotropic Glutamate Receptors At The Schaffer-Ca1 Synapse In Hippocampal Slice, Katie Marie Hoffman
The Effect Of Spillover Onto Ionotropic Glutamate Receptors At The Schaffer-Ca1 Synapse In Hippocampal Slice, Katie Marie Hoffman
Graduate Student Theses, Dissertations, & Professional Papers
Glutamate is the major excitatory neurotransmitter in the brain and is crucial for processes such as learning and memory. Due its importance as a signaling molecule, the extracellular glutamate concentration is tightly regulated, largely by the excitatory amino-acid transporters (EAATs). In these studies, we investigated the role of EAAT1-3 in synaptic transmission at the Schaffer-CA1 synapse in acute hippocampal brain slices. My results demonstrated that transport block by L-TBA resulted in glutamate spillover and activation of NMDARs. Further investigation showed that L-TBA-mediated activation of NMDARs was facilitated by the Mg2+ unblock of the receptor. Furthermore our data indicate that NMDAR …
Aufarbeitung Der Vergangenheit Through The Medium Of Myth In Heinrich Böll's Short Stories Der Mann Mit Den Messern And Nicht Nur Zur Weihnachtszeit, Marcus James Cardarelli
Aufarbeitung Der Vergangenheit Through The Medium Of Myth In Heinrich Böll's Short Stories Der Mann Mit Den Messern And Nicht Nur Zur Weihnachtszeit, Marcus James Cardarelli
Graduate Student Theses, Dissertations, & Professional Papers
German history of the 20th century was marked with unimaginable horrors and hardship. Both the First and Second World Wars left an indelible mark on the German psyche. Most specifically, the consequences of the Second World War were a turning point in German notions of cultural identity. The objective of this thesis is to analyze the various manners by which Heinrich Böll deals with the emerging cultural crisis in the post-war period of the late 1940’s and early 1950’s. I have chosen two of his short stories, Der Mann mit den Messern (1948) and Nicht nur zur Weihnachtszeit (1951), for …
Amur Tiger Predation And Energetic Requirements In The Russian Far East: New Insights From Global Positioning System Collars, Clayton Steele Miller
Amur Tiger Predation And Energetic Requirements In The Russian Far East: New Insights From Global Positioning System Collars, Clayton Steele Miller
Graduate Student Theses, Dissertations, & Professional Papers
The IUCN Red List has classified all subspecies of tigers (Panthera tigris) as endangered with prey depletion being widely recognized as one of the primary drivers of tiger declines. Due to substantial energetic requirements, tigers can only survive and reproduce in areas with healthy prey populations. This may be particularly important for Amur tigers (P. t. altaica) in the Russian Far East, living at the northern limits and with the lowest prey densities of any tiger population. Few studies have been able to rigorously investigate annual prey requirements for any tiger population. We deployed Global Positioning System (GPS) collars on …
An Inquiry Into Eco-Labeling: The Promise Of Predator Friendly Certification (Pfc), Melissa Ellen Katherine Early
An Inquiry Into Eco-Labeling: The Promise Of Predator Friendly Certification (Pfc), Melissa Ellen Katherine Early
Graduate Student Theses, Dissertations, & Professional Papers
Agricultural landscapes play key roles in preserving biodiversity through habitat protection while providing ecosystem services necessary for rural livelihoods. There is a small, but growing movement among agricultural producers to live with nature rather than to dominate nature. Within this larger agriculture movement are efforts to live with predators rather than eliminating them through lethal means. This is reflective of the changing conversation around predators in the New West. Means of co-existence include livestock guardian animals, electric fencing, fladry, range rider patrols, rotational grazing, and lights etc. One grassroots effort in this area is Predator Friendly Certification (PFC). PFC is …
Core Selection By Wolf Packs In A Human-Dominated Landscape: A Case Study In The Mountains Of Southern Poland, Nathan Alan Owens
Core Selection By Wolf Packs In A Human-Dominated Landscape: A Case Study In The Mountains Of Southern Poland, Nathan Alan Owens
Graduate Student Theses, Dissertations, & Professional Papers
The wolf populations in Europe are mostly divided between the largely undeveloped countries of Eastern Europe, and the more developed Western European nations. Poland holds a special importance as a geographical link joining these populations into one contiguous population. The territories of two wolf packs in southwestern Poland were examined through the collection of scat data. Core areas were then defined using fixed-kernel density estimation techniques and 50% isopleths. Habitat variables were then compared between core plots and non-core plots. Scat marking of both packs resembled the Hot Spots pattern of marking proposed by Zub et al. (2003), rather than …
The Changing Role Of Sámi Women In Reindeer Herding Communities In Northern Norway And The 1970-1980s Women’S Resistance And Redefinition Movement, Marcie Kaye Bremmer
The Changing Role Of Sámi Women In Reindeer Herding Communities In Northern Norway And The 1970-1980s Women’S Resistance And Redefinition Movement, Marcie Kaye Bremmer
Graduate Student Theses, Dissertations, & Professional Papers
Historically, different nations-states at different times have tried to claim authority over the Sámi in the circumpolar north. After the nation state borders were drawn in the 1700s and 1800s, separating Russia, Norway, Sweden and Finland, Norway introduced a harsh and 1800s separating Russia, Norway, Sweden and Finland, Norway introduced a harsh assimilation policy that lasted over a century. Cultural Darwinist views and national assimilationist legislation and social strategies chipped away at Sámi society and its identity as an indigenous people. Over time Sámi women found their accustomed social, economic, and political autonomy eroded. Post World War II, the emerging …
Ecological Causes Of Life History Variation Tested By Meta-Analysis, Comparison, And Experimental Approaches, Daniel Croft Barton
Ecological Causes Of Life History Variation Tested By Meta-Analysis, Comparison, And Experimental Approaches, Daniel Croft Barton
Graduate Student Theses, Dissertations, & Professional Papers
The ecological causes of life history variation among taxa and the arrangement of such variation along geographic gradients is enigmatic despite the proximity of life history traits to fitness and implications for understanding basic and applied population ecology. One classic explanation for the arrangement of avian life histories along a `slow-fast' gradient, where species at low latitudes have `slow' life history traits (low fecundity and mortality) and species at high latitudes have `fast' life history traits (high fecundity and mortality), is the increase in seasonality of resources with increasing latitude (Ashmole's hypothesis). Despite broad acceptance, this hypothesis has been supported …
The Whale And The World In Melville’S Moby-Dick: Early American Empire And Globalization, Zachary Michael Radford
The Whale And The World In Melville’S Moby-Dick: Early American Empire And Globalization, Zachary Michael Radford
Graduate Student Theses, Dissertations, & Professional Papers
Reading Moby-Dick; or, the Whale (1851), this study examines literary arguments regarding Melville’s capacity to appear prophetic through his written works in his predictions of the vast empire that America would one day become and the strategies which the country would employ to do so. In my introduction I assert that Melville is not a “Prophet,” but rather, he is a keenly analytical observer of the world around him as he recognized in America patterns of imperialism: structures he charted in his global voyages as a merchant and then a whaler. In his observations, he saw that America was not …
Examination Of Scavenging Associated With Wolves, Jamie Bankaitis
Examination Of Scavenging Associated With Wolves, Jamie Bankaitis
Graduate Student Theses, Dissertations, & Professional Papers
Forensic anthropologists often confront external influences on a body, whether they are human, animal, or environmental. One of the major and most common confounding factors for forensic anthropologists is animal scavenging and the damage this inflicts on the skeleton. The types of scavengers present vary from region to region, and in the Northwest, large carnivores such as bears, mountain lions, and canids are abundant. These types of carnivores can not only inflict incredible trauma to a skeleton, they can also disperse the remains over very large areas, making it difficult for forensic teams to recover all of the skeletal elements …
Language Change In Spanish Heritage Speakers: The Interaction Between Lexical And Grammatical Aspect, Jackelyn Kelly Van Buren
Language Change In Spanish Heritage Speakers: The Interaction Between Lexical And Grammatical Aspect, Jackelyn Kelly Van Buren
Graduate Student Theses, Dissertations, & Professional Papers
This thesis focuses on preterit and imperfect usage in the Spanish of Chilean-American heritage speakers. Spanish heritage speakers in the United States are second generation bilinguals who learn Spanish in the home from Spanish speaking parents and learn English from school and the community (Montrul 2002; Rothman 2007). When societal factors limit heritage language exposure, tense and aspect morphology is susceptible to change (Guijarro-Fuentes & Clibbens 2004). Findings of a study on 11 Chilean-American heritage speakers show that production of the preterit is overextending, resulting in less frequent use of the imperfect. Large-scale studies of US Spanish-English bilinguals’ use of …
Restoring The "Shining Waters": Milltown, Montana And The History Of Superfund Implementation, David James Brooks
Restoring The "Shining Waters": Milltown, Montana And The History Of Superfund Implementation, David James Brooks
Graduate Student Theses, Dissertations, & Professional Papers
This dissertation is a case study of a dam removal and river restoration within the nation's largest Superfund site. In 1981, the U.S. Environmental Protection Agency included Milltown Reservoir on its first list of Superfund sites. Superfund law capped two decades of the federal government's most aggressive environmental legislation. While tracking the national story of Superfund law, my story provides a local view of how individuals, organizations, and agencies shaped the Superfund process. After the EPA designated Milltown a national Superfund site, the environment itself, persistent work within the channels of public policy, and federally-mediated compromise helped restore some shine …
Sarah Palin, Conservative Feminism, And The Politics Of Family, Jasmine Rose Zink
Sarah Palin, Conservative Feminism, And The Politics Of Family, Jasmine Rose Zink
Graduate Student Theses, Dissertations, & Professional Papers
Female politicians are heavily constrained by discourses that prescribe masculine values as natural, yet at times they draw on societal expectations of femininity that allow them to utilize such discourses to their advantage. Motherhood, a feminine yet powerful role, provides such an opportunity. Capitalizing on this acceptable avenue of female power, women have strategically relied on maternal appeals since they first entered public life, often to challenge patriarchal social structures. Utilizing Lakoff‘s (2002) concept of the nation-as-family metaphor and informed by the pervasive myth of the traditional family, this analysis explores the consequences of Sarah Palin‘s use of maternal appeals …
