Growth Response Of Whitebark Pine (Pinus Albicaulis) Regeneration To Thinning And Prescribed Burn Release Treatments, Molly L. Mcclintock Retzlaff

Graduate Student Theses, Dissertations, & Professional Papers

Whitebark pine (Pinus albicaulis Engelm.) plays a prominent role throughout high-elevation ecosystems in the northern Rocky Mountains. It is an important food source for many birds and mammals, as well as a major player in high-elevation watershed maintenance, both slowing snowmelt and stabilizing soils. Whitebark pine is vanishing from the landscape due to three main factors – white pine blister rust (Cronartium ribicola) invasions, mountain pine beetle (Dendroctonus ponderosae) outbreaks, and successional replacement by more shade-tolerant tree species historically controlled by wildfire. In the past century, human activity such as fire suppression has altered these …

Explaining And Monitoring Population Performance In Grizzly And American Black Bears, Jeffrey Brian Stetz

Graduate Student Theses, Dissertations, & Professional Papers

Understanding how environmental factors influence wildlife populations is at the heart of ecology and management. Populations and their habitats are, however, inherently dynamic, which requires monitoring responses to changes in the environment. Beyond quantifying population dynamics, understanding why populations respond as they do may allow improved predictions within and across populations, ideally leading to better management. Grizzly bears (Ursus arctos) and American black bears (U. americanus) have been researched in North America for decades, providing excellent opportunities to explore ecological questions involving inter- and intraspecific competition and responses to spatial and temporal variation in resources. The wealth of data collected …

The Inflammatory Effects Of Natural And Engineered Airborne Particulate Matter In The Lung, And Related Cellular Mechanisms Of Immunity, Sophia Tracy Carvalho

Graduate Student Theses, Dissertations, & Professional Papers

Asthma, defined as a complex, chronic inflammatory disease of the airways, affects approximately 300 million individuals worldwide and is the single most common chronic disease among children. Airway inflammation is the defining characteristic of asthmatic pathophysiology; and as asthma increases in severity, the airways become more susceptible to environmental insults, including air pollutants. Wildfires and prescribed burns are significant sources of airborne particles, as well as gaseous pollution, which can temporarily increase the overall levels of air pollution over hundreds or thousands of square miles. Multi-walled carbon nanotubes (MWCNT) are increasingly used in a broad range of applications, including medical …

Enhancing Conservation With High Resolution Productivity Datasets For The Conterminous United States, Nathaniel Paul Robinson

Graduate Student Theses, Dissertations, & Professional Papers

Human driven alteration of the earth’s terrestrial surface is accelerating through land use changes, intensification of human activity, climate change, and other anthropogenic pressures. These changes occur at broad spatio-temporal scales, challenging our ability to effectively monitor and assess the impacts and subsequent conservation strategies. While satellite remote sensing (SRS) products enable monitoring of the earth’s terrestrial surface continuously across space and time, the practical applications for conservation and management of these products are limited. Often the processes driving ecological change occur at fine spatial resolutions and are undetectable given the resolution of available datasets. Additionally, the links between SRS …

Moving Toward A Holistic Menstrual Hygiene Management: An Anthropological Analysis Of Menstruation And Practices In Western And Non-Western Societies, Sophia A. Bay

Graduate Student Theses, Dissertations, & Professional Papers

Educating girls is not only their human right, but also proposed as one of the best investments for improving quality of life in developing countries (Montgomery et al. 2016, 2). Although menstruation is a universal, biological process, it is fraught with cultural stigmas and taboos throughout Western and non-Western societies. Menstrual-related absenteeism is believed to be a primary cause of missed attendance and early dropout rates, so the developing field of menstrual hygiene management (MHM) is seeking to understand and evaluate what factors are contributing to these findings. After the analyzation of the current literature, a more holistic, nine-pronged approach …

Changes In Postural Sway Behavior Across The Life Span, Maria M B N R Santos

Graduate Student Theses, Dissertations, & Professional Papers

The present study aimed to investigate human balance control by assessing postural sway on three groups representing three stages of life (6-12, 19-40 and 65-74 years old). There were 14 individuals in each group and they were tested during upright bipedal stance with either eyes open or closed. Focus was given to multiple sway indices representing multi-dimensional features of postural sway in quiet stance and included: the center of pressure area, amplitude, root mean square (RMS), velocity, jerkiness, and sample entropy. Results confirmed that children and seniors swayed more (p<.004), faster (p<.001) and their body sway was shakier (p<.001) than young adults. Seniors also presented faster (p<.006) and shakier (p<.001) sway than children and a more unpredictable pattern of body sway in time (p<.002) than children and young adults. In addition, children presented a more random anterior-posterior sway (p<.034) and a more regular medio-lateral sway (p<.043) than young adults, and a higher synchronization between anterior-posterior and medio-lateral body sway (p<.012) than young adults and seniors. We also observed that postural control of children and young adults becomes relatively more challenged in experimental situations when eyes were closed for most postural indices. In conclusion, this study suggests that multi-dimension posturography is sensitive to detect subtle age-related changes in the postural behavior and each stage of life may have their own signature patterns of postural behavior. Therefore, we expect that quantifications of this nature may be used to assess not only postural instability and fall risk but also to aid the testing of the efficacy of balance interventional protocols.

Analysis Of Sideline Concussion Screening Tools In An Athletic Setting, Steven Young

Graduate Student Theses, Dissertations, & Professional Papers

This paper serves as a primer to healthcare professionals of the now and future of sideline screening for concussion. In the past decade, significant research into sports-related concussions has expanded understanding of what is as a very complex injury. As the definition of concussion has evolved, the impact they have is put into perspective. As more research into the short- and long-term effects of concussions brings to light the effects of continuing to participate after suffering a concussion, the importance of keeping concussed athletes off the field is now understood as a potential life or death situation. With the dangers …

How Does The Million Baht Village Fund Impact Fertility In Thailand?, Kaci Felstet

Graduate Student Theses, Dissertations, & Professional Papers

This study evaluates the impact of Thailand’s Million Baht Village Fund program on household fertility decisions. Thailand’s fertility rates are alarmingly low and it is imperative to recognize the unintended consequences a microfinance program may have on fertility choices within Thailand. Using panel data from pre- and post-program years, this research identifies the change in number of babies in a household associated with getting a microloan from the Village Fund program. The quasi-experimental nature of the program and an instrumental variable model with fixed effects identifies a negative relationship between the number of babies within families and participation in the …

School Change For Sustainability, Ryder Delaloye

Graduate Student Theses, Dissertations, & Professional Papers

The welfare of current and future generations is diminished due to unprecedented levels of ecological degradation that is a result of accelerating levels of per capita consumption. Sustainability education is being widely embraced as an applied strategy for addressing both unchecked consumption and environmental degradation (Brown, 2003). Yet, little is known about how schools adopt and implement sustainability education. The means by which to engage and foster sustainability education is not well researched. This qualitative research study seeks to address the following research question: How did students and faculty at each school site go about the process of creating and …

Aerodynamics And Ecomorphology Of Flexible Feathers And Morphing Bird Wings, Brett Klassen Van Oorschot

Graduate Student Theses, Dissertations, & Professional Papers

Birds morph their wings during a single wingbeat, across flight speeds, and among flight modes. Such morphing may allow them to maximize aerodynamic performance, but this assumption remains largely untested. We tested the aerodynamic performance of swept and extended wing postures of 13 raptor species in three families (Accipitridae, Falconidae, and Strigidae) using a propeller model to emulate mid-downstroke of flapping during takeoff and a wind tunnel to emulate gliding. Based on previous research, we hypothesized that 1) during flapping, wing posture would not affect maximum ratios of vertical and horizontal force coefficients (CV:CH), and that 2) extended wings would …

Drivers And Feedbacks Of The Fire-Grazing Interaction In The Northern Great Plains, Jacob E. Powell

Graduate Student Theses, Dissertations, & Professional Papers

The fire-grazing interaction is well studied in mesic grasslands worldwide, but research is lacking in semiarid systems. In addition, the fire-grazing interaction reduces the invasion of exotic forage species in mesic grasslands by increasing the scale of grazing selection and may be a tool to control invasive plants in other grasslands. We examined the principal drivers and feedbacks of the fire-grazing interaction on the strength of cattle grazing selection, forage quantity and quality, and vegetation structure and composition in two pastures in northeast Montana at The Nature Conservancy’s Matador Ranch. We also determined the influence of time since fire, within …

Estimating The Effects Of Overstory Retention, Vegetative Competition, And Site Quality On The Height Growth Of Small Ponderosa Pine Trees Using Regression Quantiles, Colin P. Kirkmire

Graduate Student Theses, Dissertations, & Professional Papers

Ponderosa pine (Pinus ponderosa C. Lawson) forests in the Inland Northwestern region of the US are increasingly managed under multi-aged silvicultural systems that provide stand structure for wildlife habitat, timber production, enhanced aesthetic, or restoration of presettlement conditions (O'Hara 2005). Partial retention harvest, where an element of the previous stand's overstory structure is retained, is commonly used to achieve a multi-aged stand structure. However, little is known about how ponderosa pine trees in the understory respond to overstory and understory competitive factors following partial retention harvest. The height growth of small trees was hypothesized to be influenced by site …

Visions Of Sovereignty: Tribal Sovereignty Through The Lenses Of Postcolonialism, Indigenous Film, And Visual Anthropology, Martin I. Lopez

Graduate Student Theses, Dissertations, & Professional Papers

Tribal sovereignty has been a topic of discussion since the beginning of colonization in America. Anthropological thought, especially postcolonialism theory, addresses how colonialism can be analyzed to gain a better understanding of Indigenous perspectives on sovereignty. Visual sovereignty, an example of Indigenous Film, is an interdisciplinary approach that can contextualize in specific histories and social interactions all while serving individual tribes, depending on which tribe the filmmaker represents. A film, for instance, can be edited in a way to convey Indigenous ideas of time and space and staged presentations of oral histories that are nearly impossible to display through written …

An Investigation Of The Relations Between Stress And Prospective Memory, Brandon T. Stewart

Graduate Student Theses, Dissertations, & Professional Papers

Prospective memory (PM) is a future-oriented memory system that entails “remembering to remember” intentions, or to perform actions in the future. People spend significant portions of their day-to-day lives forming and acting on intentions, and the ability to successfully generate, retain, and complete these intentions has important implications for one’s daily functioning and quality of life. Another common human experience is stress, whether that be short-term, acute stress, or long-term, chronic stress. Despite the significance and ubiquity of both PM and stress, the research base documenting the relations between them is sparse. This topic area necessitates additional research to delineate …

¬Multilocus Phylogeny Of The Lichen Family Megasporaceae, Tim B. Wheeler

Graduate Student Theses, Dissertations, & Professional Papers

The lichen symbiosis is one of the oldest studied mutualisms; in fact, Frank and De Bary coined the term "symbiosis" while studying lichens (Frank, 1877; De Bary 1879). The widespread, stable association between the mycobiont and photobiont in lichens offers an ideal system for the study of co-evolution. The recent application of molecular data to lichens has begun to unveil the complexities involved in these associations (Upreti et al. 2015, Spribille et al. 2016). Lichenized fungi make up a huge fraction of fungal diversity (Nash 2008), yet very little is known of their genetic diversity. Fungal taxonomy is notoriously difficult …

Universal Depression Screening In Student Health Centers Across U.S. College Campuses: Prevalence And Characteristics Associated With Use, Ivie English

Graduate Student Theses, Dissertations, & Professional Papers

Universal depression screening at university student health centers can increase identification and treatment of depression among college students, but the rates of screening in these settings were, until now, unknown (Shepardson & Funderburk, 2014). The U.S. Preventive Services Taskforce (USPSTF), American College Health Association, and other organizations have recommended that all primary care settings universally screen for depression, provided that necessary supports are in place (USPSTF, 2016; ACHA, 2010). Notably, others disagree (Joffres et al., 2013; Mitchell et al., 2009; Gilbody et al., 2005). An online survey was electronically mailed to 493 college health center directors and/or medical directors of …

The Role Of Behavior In The Effectiveness Of Indoor Air Pollution Interventions: Results From The Artis Study, Madison J. Cole

Graduate Student Theses, Dissertations, & Professional Papers

Using panel data from a randomized placebo-controlled trial of a wood stove changeout and air filter interventions, this study addresses the role of behavior in the efficacy of air quality interventions. The effectiveness of an intervention in improving air quality depends on how households respond to and use them. Two important responses are whether the target population complies with the requirements of the intervention and whether users adjust other behaviors that can affect air quality.

This paper’s results are consistent with prior studies in finding that in the absence of interventions, a number of behaviors can affect indoor air pollution, …

Assessing Stream Channel Restoration: The Phased Recovery Framework, Jacob M. Dyste

Graduate Student Theses, Dissertations, & Professional Papers

Channel reconfiguration projects command a large portion of stream restoration resources, while long-term monitoring and research is severely underfunded and rarely implemented. This has led to a limited knowledge base about ecological response and efficacy. Although channel reconfiguration projects are being implemented to restore biological function to lotic systems, the document responses are highly variable and little evidence has shown these projects are reaching their target goals. I predicted the inconsistent response to these projects is the result of disturbance-induced successional processes and catchment-scale water quality impairment. To address how these endogenous and exogenous factors influence stream response to channel …

Mirage: A Novel Multiple Protein Sequence Alignment Tool, Alex Nord

Graduate Student Theses, Dissertations, & Professional Papers

A fundamental problem in computational biology is the organization of many related sequences into a multiple sequence alignment (MSA) [2]. MSAs have a range of research applications, such as inferring phylogeny [22] and identifying regions of conserved sequence that indicate functional similarity [18]. In the case of protein isoforms, MSAs are valuable tools for transitively annotating post-translational modifications (PTMs) by enabling information transfer between known PTM sites and the sites that they align to [11].

For protein MSA tools, one challenging biological phenomenon is alternative splicing, wherein identical genomic sequence will differentially select from a subset of available coding regions …

Backward Masking With Simultaneous Early, Middle And Late Evoked Potentials, Silas Smith

Graduate Student Theses, Dissertations, & Professional Papers

Auditory processing disorders (APDs) affect a diverse range of people. These types of disorders impair auditory function, despite the outer, middle and inner ear maintaining proper function and health. APD is not necessarily related to auditory thresholds. When people with APD have difficulty discriminating sounds in connected speech, it may be due in part to an effect called Backward Masking (BM). Masking occurs when one stimulus inhibits another, which can lead to a variety of impairments. The neural locus of APDs is for the most part unknown, including the specific conditions which cause BM. A better understanding of these processes …
