Developmental, Ecological, And Life History Influences On Predator-Induced Plasticity In Songbirds, James Christopher Mouton

Graduate Student Theses, Dissertations, & Professional Papers

Predation is a ubiquitous ecological force that plays a major role in the evolution of phenotypes. Where the predation risk is predictable and variable, prey species are expected to evolve plasticity in traits that reduce the likelihood of being killed and eaten by predators. Such plasticity may be especially critical for the survival of dependent offspring because they are particularly vulnerable to predators and suffer high levels of predation across taxa. Yet the fitness effects of predator-induced plasticity can vary across life stages, differ between parents and offspring, or be mediated by interactions with other species in the community. The …

Learning From Stone: Using Lithic Artifacts To Explore The Transmission Of Culture At Bridge River, British Columbia, Anne V. Smyrl

Graduate Student Theses, Dissertations, & Professional Papers

Inherent in all tool-making traditions is the necessity of teaching the next generation of toolmakers. The learning process, although crucial to our understanding of past societies, is difficult to study archaeologically, due to its intangibility. However, some technologies leave visible traces of their production. Key among these are chipped stone tools, known as lithics, which leave distinct archaeological traces of each part of the creation processes. Modern experimenters have recreated these processes, and as a result, have revealed archaeologically-visible differences between novice and expert knappers. These can be identified in archaeological lithic assemblages, and serve as a starting point for …

Local Knowledge And Climate Information: The Role Of Trust And Risk In Agricultural Decisions About Drought, Adam J. Snitker

Graduate Student Theses, Dissertations, & Professional Papers

Climate change is projected to dramatically impact agricultural production across the world. Agricultural producers must adapt to changing conditions by implementing practices and utilizing knowledge that creates resilient operations. This study explores how Montana farmers and ranchers use of different types of knowledge during periods of drought and how risk perceptions and trust influence the use of knowledge. To understand the role trust and risk in producers’ use of local knowledge and climate information, I conducted five focus groups with 34 Montana agricultural producers. Producers explained that they encounter many agriculture-related risks, including uncertain forecasts, financial losses, and adverse weather. …

Soil Moisture Drives Canopy Water Content Dynamics In The Western U.S., Drew S. Lyons

Graduate Student Theses, Dissertations, & Professional Papers

Drought stress is a major contributing factor to adult tree mortality and limits regeneration across the globe. Drought effects are often studied on a site level, but recent advances in remote sensing allow for observations of plant water status across broader geographic scales. The vegetation optical depth (VOD) derived from satellite sensor microwave backscatter has been shown to be sensitive to canopy water content, and can therefore provide useful information on how plant water status changes over time. We develop an index which quantifies the normalized difference between diurnal VOD retrievals (nVOD) across the western U.S. to determine where plant …

Methods For Estimating Mountain Goat Occupancy And Abundance, Molly Mcdevitt

Graduate Student Theses, Dissertations, & Professional Papers

Abundance and occupancy are two parameters of central interest to the field of ecology. Furthermore, accurate (both precise and unbiased) estimates are key pieces to the puzzle of effective wildlife management decision-making. While there exist a variety of sampling techniques and statistical models for effectively estimating population parameters for frequently encountered and large mammals, methods for sampling unmarked and rare species are few and far between. The first step to acquiring usable parameter estimates is through the use of sampling theory and incorporation of probabilistic sampling designs to collect count-data and occurrence-data. Often, it is assumed that probabilistic sampling designs …

A Structural And Biochemical Study On Ric-8a, An Intracellular Guanine Nucleotide Exchange Factor And Folding Chaperone For The Inhibitory G-Protein Alpha Subunit-1, Baisen Zeng

Graduate Student Theses, Dissertations, & Professional Papers

Heterotrimeric G-proteins (Gαβγ) regulate many cellular processes in the G-protein signaling pathways. The α-subunit (Gα) in the heterotrimer is activated by G-protein-coupled receptor (GPCR) as the guanine-nucleotide exchange factor (GEF), which catalyzes the GDP-release and GTP-binding reactions at Gα nucleotide-binding site, at the cell membrane. Intracellular GEFs for Gα subunits have been identified; among them, the mammalian isoform A of resistance to inhibitors of cholinesterase-8 (Ric-8A) catalyzes nucleotide exchange and functions as a folding chaperone for inhibitory Gα (Gαi1). In a nucleotide-free complex with Gαi1, Ric-8A likely assumes the GEF and chaperone roles by inducing a molten globule-like state. Tall …

Environmental Variation And Sexual Selection In The Mountain Bluebird (Sialia Currucoides), Sara A. Berk

Graduate Student Theses, Dissertations, & Professional Papers

Sexual selection acts on traits that increase mating success, either through mating preferences or intrasexual competition for access to mates. For traits to be honest, we expect sexually selected traits to reflect individual condition at the time of trait development. Furthermore, when sexual selection operates through mating preferences, we also expect traits to indicate benefits (direct or indirect) that females receive for exercising their preference. If sexual selection acts through differential success in intrasexual contests over mates, we expect traits to indicate resource holding potential, or fighting ability. These links between individual condition, trait quality, and performance maintain honesty, because …

The Anzick Artifacts: A High-Technology Forager Tool Assemblage, Samuel Stockton White V

Graduate Student Theses, Dissertations, & Professional Papers

The Anzick Site (24PA506) is a multi-component archaeological site located in the Shields River Valley of south-central Montana approximately 125 km north of Yellowstone National Park. The site was accidentally discovered in 1968, leading to the unfortunate destruction of its archaeological context. Included in the recovered elements of the site are the fragmentary human remains of two individuals, as well as approximately 116 lithic and osseous tools diagnostic of Clovis Culture technology. These tools were thickly covered with red ochre, as was one set of remains, presumably indicative of a burial from which osseous tool samples were dated to approximately …

Prevention Of Crystalline Silica-Induced Inflammation By The Anti-Malarial Hydroxychloroquine, Rachel Dawn Burmeister

Graduate Student Theses, Dissertations, & Professional Papers

Exposure to inhaled crystalline silica (cSiO2) is common in occupations where there is cutting, milling, or grinding of cSiO2 containing material. The Occupational Safety and Health Administration estimates that over 2 million workers may be exposed to inhaled cSiO2 in the United States. Inhalation of cSiO2 causes acute and chronic inflammation and may lead pulmonary diseases such as silicosis, as well as an increased risk of developing autoimmune diseases.Unfortunately, treatment of cSiO2-induced lung diseases is limited and primarily focused on supportive care.

Inflammation caused by cSiO2 begins when, cSiO2 particles are phagocytized by alveolar macrophages. Interaction between the particle and …

Spatiotemporal Dynamics Of Nitrogen And Carbon Biogeochemistry In A Wetland-Stream Sequence, Patrick E. Hurley

Graduate Student Theses, Dissertations, & Professional Papers

Studies of aquatic ecosystems often segregate streams from the influential ponds, lakes, and wetland zones that act as important transitions between terrestrial and fluvial systems. Across the aquatic landscape, these zones interact to form linked ecosystems that function as discrete nutrient processing domains, shifting biogeochemical signals due to spatial and temporal variability in hydrologic and biologic controls. Using a mass-balance approach, we profiled nutrient dynamics along a 23-km wetland-stream sequence over three seasons. Hydrologic, morphologic, and biologic conditions, as well as landscape attributes, were quantified to determine potential controls on biogeochemical cycling in a tributary of the Upper Clark Fork …

Tiger Monitoring In Bhutan Using Non-Invasive Genetic Tools, Tashi Dhendup

Graduate Student Theses, Dissertations, & Professional Papers

Large carnivores are one of the most threatened group of animals in the world. They suffer from prey depletion, persecution by humans, and habitat loss and fragmentation which are extensively driven by anthropogenic activities. One such species is the tiger Panthera tigris. Tigers are found in thirteen countries in Asia and are protected across the range; however, tiger numbers have declined as an after effect of habitat loss, prey depletion and poaching. Human-induced changes have reduced the tiger's historical range to about 7% in which a little more than 3900 tigers are found. Most of these individuals currently exist …

Human Vs. Non-Human Bone: A Non-Destructive Histological Method, Haley N. O'Brien

Graduate Student Theses, Dissertations, & Professional Papers

Species identification is one of the first steps in the analysis of bone fragments in both forensic and archaeological contexts. Current methods for human vs. non-human taxa identification include morphoscopic, histological, and DNA analyses in order to determine forensic significance and assess what is present in an assemblage. This study will use an MA1000 AmScope camera microscope to examine the longitudinally fractured surface of cortical bone fragments to gauge if non-destructive taxa identification is possible from fragmentary remains without morphologically identifying features. This method is testing for a notable difference in human vs. bovid vs. cervid endosteal cortical bone without …

Self-Compassion And Fear Of Compassion As Mediators In The Relationships Of Childhood Invalidation With Emotion Dysregulation And With Borderline Personality Disorder Characteristics, Priyadarshani Florence Loess

Graduate Student Theses, Dissertations, & Professional Papers

According to Linehan’s (1993) biosocial theory, the core feature of Borderline Personality Disorder (BPD) is emotion dysregulation, which arises from emotional vulnerability and an inability to effectively modulate emotional experiences. Linehan posits that the transaction of environmental invalidation with biological vulnerabilities leads to the development of BPD. Those with BPD often live painful, chaotic lives, experience extreme emotions and impulsivity, and engage in self-injurious behavior. While there are treatments with demonstrated effectiveness, they do not work for everyone, and there is a need to continue to advance interventions. Self-compassion is extending nonjudgmental kindness to one’s self during stress, failure, or …

Population And Breeding Ecology Of Sagebrush Steppe Songbirds, Kayla Ann Ruth

Graduate Student Theses, Dissertations, & Professional Papers

Sagebrush steppe is one of the most threatened ecosystems in North America. Domestic livestock grazing is the dominant land use of sagebrush steppe across the west. Rest-rotation grazing systems can be a conservation management tool, most recently, by the Natural Resource Conservation Service - Sage Grouse Initiative (SGI). The goal of SGI is to encourage private landowners to use a livestock grazing regime that maintains or improves habitat for greater sage-grouse (Centrocercus urophasianus), as well as improve rangeland productivity. Songbirds are biological indicators that can assess the health of sagebrush steppe. Avian adult density estimates are often used …

Sexual Dimorphism In Skeletal Trauma Associated With Intimate Partner Violence (Ipv), Keith Biddle

Graduate Student Theses, Dissertations, & Professional Papers

Once known as “Domestic Violence”, Intimate Partner Violence, or IPV, is a problem as old as humanity. Even in our modern era, it continues to plague even the most “enlightened” or “advanced” cultures and societies. Much has been written about the issue from Sociological and psychological aspects and while there is some consensus in the medical field regarding the patterns of injury associated with IPV, that consensus has yet to reach the field of forensic anthropology. It is to this end that this study has been conceived.

The proposed project has three parts. The first part is a validation study …

Can Nonhumans Be Victims Of Genocide?, Kirstin Waldkoenig

Graduate Student Theses, Dissertations, & Professional Papers

“Genocide” appears commonly in critical animal studies literature and sparsely in philosophy to describe human-caused violence against nonhuman beings. However, such uses of the term have rarely been informed by relevant work in genocide studies, nor otherwise formally substantiated. This thesis explores what is at stake when employing the term and proposes a model for appropriate application to nonhuman contexts. Claudia Card’s notion of genocide as social death allows for the consideration of nonhuman animals as victims of genocide. Social vitality is important to the lives of some nonhuman animals and its forcible diminishment results in social death for those …
