Item Jaws: a love story(Montana State University - Bozeman, College of Arts & Architecture, 2024) Kemp, Morgan Markley; Chairperson, Graduate Committee: Jim ZimpelApproximately 100 million sharks are killed per year due to finning, fishing, and beauty industries. The destruction of a critical apex predator has been overlooked due to a lack of empathy for the venerable creature. This is due to the negative impacts from the film Jaws and the subsequent rise in fear mongering media that has created a false persona that sharks are blood-thirsty man-eating monsters meant to be feared and worthy of defeat. In order to generate positive change to save sharks, the populations perception of what sharks are must be changed. By creating a body of artwork inspired by the true beauty of sharks, fearful opinions of sharks can be exchanged for respect and admiration. Subtilities of the atrocities afflicting sharks can be introduced in a palatable way resulting in empathy that can enact real change for shark conservation.Item Prairie gothic(Montana State University - Bozeman, College of Arts & Architecture, 2024) Hedge, Kristen Marie; Chairperson, Graduate Committee: Jeremy HatchPrairie Gothic is my understanding of how I have been shaped by experiences of grief and mourning, informed by aesthetics of the Midwest and Western landscape. My research is based on mourning adornment and dress from the Victorian period (approx. 1820-1914), and its impact on Midwest and Western American culture from the perspective of the working class. As the customs surrounding mourning were extravagant in every way, the typical working-class person could not afford to express their love and mourn with gold, diamonds and silk. The objects I have come across in my research express a kind of sentimentality that allows people to express and contain their grief in these objects as a form of art. Everyday materials that are typically overlooked can become reliquaries containing memories and information about the deceased. It is these materials that I used in my work to highlight the importance of family and love.Item Impacts of forest mortality on streamflow in whitebark pine forests within the greater Yellowstone ecosystem(Montana State University - Bozeman, College of Letters & Science, 2024) Rautu, Teodora Stefana; Co-chairs, Graduate Committee: Brian V. Smithers and Danielle E. M. UlrichIncreasing forest mortality across the western U.S. raises concerns about its impact on streamflow. The hydrologic role of whitebark pine (Pinus albicaulis Engelm.) is of particular interest given its ongoing decline and prevalence at the upper treeline where precipitation is highest. Understanding the link between disturbed whitebark pine forests and streamflow is essential for better informing water resource management. In Chapter One, I investigated streamflow changes in two Wyoming whitebark pine watersheds: Upper Wind River (53% area affected by beetle outbreak) and Buffalo Fork (53% area affected by beetle outbreak and fire). Streamflow significantly increased post-beetle for Upper Wind River but did not significantly change post-disturbance for Buffalo Fork, attributed to the fire's limited spatial extent and post- beetle effects potentially occurring in the pre-disturbance period. In Chapter Two, I integrated Leaf Area Index into a hydrologic model to reflect changing canopy conditions and assessed water balance variables that drove the observed changes in streamflow in Chapter One. I found that an increase in annual precipitation primarily led to the increase in observed streamflow more so than forest mortality, and snowpack and snowmelt were consistent predictors of streamflow metrics. My findings suggest monitoring snow dynamics for accurate real-time and future streamflow forecasting. In Chapter Three, I used streamflow field data and the same hydrologic model to assess the impact of increasing tree mortality on streamflow within a whitebark pine- dominated watershed in Big Sky, Montana. After simulating mortality levels ranging from 0-90% for one year, tree mortality did not substantially impact streamflow until the 90% mortality level where annual flow and late summer flow substantially increased. Considering that mortality levels between 25-50% are more representative of whitebark pine mortality in one year, the lack of substantial impacts on snowpack and streamflow at the 25-50% mortality levels challenges the traditional assumption that whitebark pine mortality would lead to reduced snowpack and reduced late summer flow in open watersheds with 30% forest cover. Future studies should assess the multi-decade impacts of whitebark pine mortality on hydrologic processes and consider species differences in evapotranspiration as other subalpine species replace whitebark pine.Item Ani(Montana State University - Bozeman, College of Arts & Architecture, 2024) Gorham, Olivia Marie; Chairperson, Graduate Committee: Jennifer BolesThis film and accompanying paper thesis delve into the intricacies of life within a nunnery amidst the landscapes of the Himalayas. Through the lens of sensory ethnography and observational filmmaking, the project offers a nuanced portrait of the daily rituals, spiritual practices, and communal relationships that define the existence of the nuns within this remote sanctuary. Employing asynchronous sound and poetic filmmaking techniques, the project reassesses traditional documentary conventions, aiming to evoke a visceral and immersive experience for the audience. As viewers exist within the nunnery's spaces, they are enveloped by the resonant chants of prayers, the whispers of mountain winds, and the rustle of prayer flags, inviting them into a state of contemplation and introspection. Drawing on extended periods of intimate engagement with the space, the film captures moments of quiet reflection, collective meditation, and acts of devotion that speak to the rhythms of monastic life. Through lingering shots and evocative compositions, it seeks to convey not only the outward manifestations of religious practice but also the inner landscapes of the relationships between the nuns and their environment. In tandem with the film, the accompanying thesis paper provides a theoretical framework for understanding the methodological and aesthetic choices underlying the project. It explores the intersection of sensory ethnography, observational filmmaking, and poetic representation, arguing for their collective potential to convey the complex dimensions of lived experience. Ultimately, Ani invites viewers to contemplate assumption, relationality, and human curiosity.Item Alone in the West with a portrait of art history(Montana State University - Bozeman, College of Arts & Architecture, 2024) Krause, Nicholas O'Brien; Chairperson, Graduate Committee: Rollin BeamishHow do we find our place in the historical narrative of art on the vast continuum of human creativity? Art is a reflection and director of culture that embodies historic movements and fundamental principles that enable us to see a continuity and a relationship to humanity over the centuries. To understand our place in the historical canon we must reflect on the past to evaluate our current situation. We draw from the past to inform our understanding of art and culture to take responsibility for the direction of art in the future. To do this we must find a relationship to the aesthetics of historical, cultural movements and investigate the ideas and processes of different ages, to see how we can relate to them, and figure out how to represent the expanding collection of culture and art going forward.Item None of it is true, all of it is real(Montana State University - Bozeman, College of Arts & Architecture, 2024) Godfrey, Tiana Alyse; Chairperson, Graduate Committee: Rollin BeamishTruth relies on objectivity, but we are not capable of objectivity. In contrast, reality is subjective. With this in mind, I begin with the position that truth cannot be understood as anything other than a person's reality. In other words, objectivity can only be experienced subjectively. Through my art, I try to explore the objective subjective and subjective objective, and play with this paradox. For this thesis, I specifically discuss how I believe I have found an interesting paradoxical playground through painting an immediate image of what is credibly an objective place, while being cognizant of what felt true to me within that shared place.Item Irrigation ditches as novel intermittent stream networks that provide energetic subsidies to terrestrial ecosystems via aquatic insect emergence(Montana State University - Bozeman, College of Letters & Science, 2024) Heili, Nathaniel Maxwell; Chairperson, Graduate Committee: Wyatt F. CrossNon-perennial streams dominate fluvial networks, comprising over half of lotic ecosystems globally. Although little attention has been paid to these systems relative to those that are perennial, perhaps even less is known about the ecology of artificial intermittent streams. In irrigated river valleys, ditches comprise a substantial proportion of surface water networks, but little is known about their relative contributions to lotic habitat, freshwater biodiversity, and ecosystem processes. Because ditches are abundant and permeate arid floodplains, they create new opportunities for cross-ecosystem subsidies through emergence of adult aquatic insects. Here, we mapped the extent of an irrigation ditch network relative to natural surface waters in the Gallatin River Valley, Montana, USA. We also quantified the magnitude, composition, and phenology of aquatic insect emergence in ditches throughout a full irrigation season and compare emergence to nearby natural streams in the valley. We found that non-perennial streams, both natural and artificial, dominated the surface-water network, representing over 70% of total length. Irrigation ditches also constituted 37% and 23% of total length and surface area of all waterbodies in the valley, respectively. Insect emergence production from ditches averaged 32.0 mg m -2 d -1 and exceeded fluxes from nearby natural streams, which contained more classically sensitive taxa (i.e., Ephemeroptera, Trichoptera, and Plecoptera). Ditches varied in water temperature, substrate size, and flow permanence, leading to distinct emergence timing, species composition, and magnitudes of biomass flux. One of the study ditches dried early because of more 'junior' water rights, but this ditch provided the largest emergence subsidy, including a pulse of dipteran emergence at the onset of flow cessation. Annual production from intermittent ditches was ~6 g m -2 y -1 and was comparable to estimates from natural perennial streams. Although our study focused on one river valley of the western US, results suggest that these ecosystems contribute broadly to lotic habitat, heterogeneity, and cross-ecosystem subsidies via aquatic insect emergence. Given increasing demand for water and changes to flow regimes and water management driven by climate change, additional study is needed on these novel and underappreciated artificial ecosystems.Item Smart wildlife monitoring: evaluating a camera trap enabled with artificial intelligence(Montana State University - Bozeman, College of Agriculture, 2024) Kaltenbach, Taylor Louise Gregory; Chairperson, Graduate Committee: Jared T. Beaver; Jeffrey C. Mosley (co-chair)Wildlife-livestock conflicts, including depredation, disease transmission, and resource competition, present significant challenges to both the ecological and economic aspects of ranching operations. These conflicts can undermine the sustainability of ranching operations as well as the conservation of wildlife in working landscapes. Leveraging timely and precise data on wildlife activity, distribution, and their interactions with livestock are crucial for enhancing ongoing conflict mitigation efforts and to help sustain wildlife on working landscapes. I evaluated the potential of an artificial intelligence (AI)-enabled camera trap to limit false positive images and provide real-time monitoring of wildlife presence while reducing data overload. In Study 1, I compared the performance of a prototype, edge AI-enabled camera trap (Grizzly Systems) with 2 traditional, non-AI camera traps (Browning and Reconyx) at 8 sites across 3 ranches in south-central Montana, USA, from mid-June through mid-September 2023. I also evaluated the influence of site-specific environmental conditions, including air temperature, wind speed, cloud cover, and vegetation type on camera trap performance. The Grizzly Systems camera trap captured fewer false positive images but exhibited a higher rate of missed detections compared to the Browning and Reconyx camera trap models. Across all 3 camera trap models, the probability of positive detections declined with warmer air temperatures and greater wind speeds. In addition, warmer air temperatures positively influenced missed detections by Reconyx and Grizzly Systems camera trap models, but warmer air temperatures negatively influenced missed detections by Browning camera traps. In Study 2, I compared the performance of a cellular-connected AI-enabled Grizzly Systems camera trap, equipped with an automated image processing and notification reduction workflow, to a traditional, non-AI, cellular-connected Reconyx camera trap at 2 sites in south-central Montana, USA from mid-April to mid-June 2023. The AI-enabled, cellular-connected Grizzly Systems camera trap successfully sent real-time notifications of wildlife presence and transmitted significantly fewer false positive images than the cellular-connected Reconyx camera trap. However, the Grizzly Systems camera trap sent substantially fewer notifications of positive detections than the Reconyx camera trap, which are likely attributed to missed detections by the Grizzly Systems camera trap.Item Resilient: Norfolk's race against the rising seas(Montana State University - Bozeman, College of Arts & Architecture, 2024) Hermsen, Erinn Catherine; Chairperson, Graduate Committee: Cat DaleResilient is told in the expository mode of documentary filmmaking. The characters' stories are woven together through the use of talking-head characters who provide voice-of-authority commentary with their first-hand stories and expert testimony, as well as an omniscient narrator that provides additional context and information. The film presents a problem/solution structure (Nichols 22) supported by evidentiary editing. Resilient presents the problem of flooding due to climate change-induced sea level rise and introduces solutions. Norfolk's infrastructure adaptation projects aim to protect the city in the short-term while the city can solve the long-term issue of living along rising sea levels. The characters' stories serve to ultimately further the argument, which is in line with key characteristics of the expository mode (Nichols 121). Two relevant films I watched as research for my own had similar approaches to storytelling. "Sinking Cities: Miami" and "Climate Crisis: Flooding" also used the expository mode of documentary. The stories were also told through talking-head experts who provided voice-of-authority expert testimony, as well as an omniscient narrator. The characters' stories provided first-hand experience and knowledge that supported the films' problem/solution storylines.Item The mental wellness conversation curriculum: better understanding the gap between facilitator training and community conversations(Montana State University - Bozeman, College of Education, Health & Human Development, 2024) Sutphen, Katharine Nora; Chairperson, Graduate Committee: Michelle U. Grocke-DeweyThis thesis whether the MSU Extension Mental Wellness Conversation Curriculum (MWCC) is effective in terms of adequately preparing newly trained facilitators to lead their own community based MWCC conversations. The MWCC is a mental health and wellness conversation pedagogy designed to be delivered in rural communities by community volunteer facilitators. The Social Ecological Model (SEM) explains the nuance of this program and incorporates supporting studies that leverage community-based and volunteer-led techniques. The results from the volunteer training evaluation data, a pre-and post- survey, indicate a positive change in awareness, knowledge, and beliefs among the 24 facilitators regarding specific mental health and wellness content presented in the training. The results indicate high favorability from volunteers regarding their experience at the MWCC training and optimism about the future of MWCC as a mental health and wellness program. However, despite favorable and statistically significant improvements from pre and post training data, there has been stagnation among community volunteers leading their own MWCC conversations. In response to this finding, a follow up exploration into possible explanations was conducted. Results indicated the importance of volunteer training as a predictor of volunteer engagement success. Additionally, the following themes were explored to understand the impact they had on MWCC volunteer engagement: 1) the duality of agency and autonomy in volunteering, 2) the explanatory power of the Self-determination Theory as it relates to volunteer motivation, 3) the importance of volunteer recruitment strategies and clear objectives, 4) the value of skills-based volunteering, and 5) the importance of content delivery within a training to maximize future engagement. Minor adaptations to the MWCC training and evaluation efforts would be beneficial for improved volunteer engagement going forward. Future research suggestions include further exploring how social context and environmental factors may impact the success of community based MWCC conversations.
