Hunters In The Garden: Yup’Ik Subsistence And The Agricultural Myths Of Eden, Benjamin Kuntz
Hunters In The Garden: Yup’Ik Subsistence And The Agricultural Myths Of Eden, Benjamin Kuntz
Graduate Student Theses, Dissertations, & Professional Papers
Yup’ik writers and Yup’ik subsistence offer valuable challenges, parallels, and alternative models to mainstream nature writing’s discourse surrounding human relationships to the land, a discourse that carries an inherent agricultural bias. An introduction to western Alaska’s Nunivak Island provides context for Chapter 1, which demonstrates the fluidity of cultural, geographical, and historical margins through discussion of the works of Yup’ik journalist John Active and historian and ethnographer James Clifford. Chapter 2 provides an overview of Yup’ik subsistence centered around the community of Bethel, Alaska, then subjects mainstream nature writing, represented mostly by Wendell Berry, to critiques supplied by Canadian anthropologist …
The Role Of L-Carnitine In Preventing Mitochondrial Dysfunction After Neonatal Hypoxia-Ischemia, Thomas Fredrick Rau
The Role Of L-Carnitine In Preventing Mitochondrial Dysfunction After Neonatal Hypoxia-Ischemia, Thomas Fredrick Rau
Graduate Student Theses, Dissertations, & Professional Papers
Neonatal hypoxia-ischemia (HI) represents an intractable clinical condition that lacks an effective treatment and results in blindness, cerebral palsy, and cognitive deficits. A primary mechanism of cell death induced by neonatal HI is mitochondrial dysfunction leading to metabolic crisis and apoptosis. L-carnitine (LCAR) is an endogenous compound that transports fatty acids across the mitochondrial membrane for metabolism, buffers endogenous acyl-coA pools and improves the health and efficiency of the mitochondria. In light of the mitochondrial dysfunction observed after HI we hypothesized treatment with LCAR would reduce cell death after HI. Using a novel rat hippocampal slice culture model we observed …
The Role Of Silicates In Interstitial Lung Disease, Francisco Jose Leyva
The Role Of Silicates In Interstitial Lung Disease, Francisco Jose Leyva
Graduate Student Theses, Dissertations, & Professional Papers
Interstitial Lung disease (ILD), produces disruption of alveolar walls with loss of functionality and accumulation of scar tissue. Asbestosis and silicosis are the ILD produced by the inhalation of asbestos fibers or silica particles respectively. An increase in prostacyclin release after exposing endothelial cells to asbestos has been reported. This study attempts to elucidate the role of lung epithelial cells in the generation of asbestos induced ILD. A cell model to study crocidolite-induced toxicity was developed using LA-4 cells, previously characterized as alveolar type II cells. LA-4 cells when exposed to crocidolite had a decrease in viability and an increase …

The Role Of The Macrophage In Asbestos Induced Autoantibody Production, David J. Blake
Graduate Student Theses, Dissertations, & Professional Papers
Environmental exposure to silicate compounds such as silica and asbestos has been associated with increased autoimmune responses and the development of autoimmune disease in humans. Residents of Libby, MT have experienced significant asbestos exposure due to an asbestos contaminated vermiculite mine near the community over several decades. Residents have developed numerous asbestos-related diseases as well as increased autoimmune responses. However, the exact mechanism by which Libby amphibole asbestos generates autoimmune responses is unclear. To elucidate a possible mechanism for asbestos induced autoimmunity, the cellular effects of Libby amphibole asbestos were characterized in vitro using a phagocytic murine macrophage cell line, …

The Shield Bearing Warriors Of Bear Gulch: A Look At Prehistoric Warrior Identity In Rock Art And Places Of Power, Melissa Marie Ray
Graduate Student Theses, Dissertations, & Professional Papers
Centuries ago prehistoric warriors carved and painted their identities on the sandstone cliffs of Bear Gulch 24FR002. Bear Gulch is the premier shield bearing warrior site on the Northern Plains; in fact it holds the most shield bearing warriors known on the Northern Plains at a single site. Shield bearing warrior consists of an anthropomorph with a shield for a body, a head, feet, and weapons or flags protruding out from behind the shield. At Bear Gulch there are elaborate headdresses, flags, shields, weapons, bustles, and wolf tail moccasins. Many of these elements are only found in the ethnographic literature …

The Tongue River Bison Jump (24rb2135): The Technological Organization Of Late Prehistoric Period Hunter-Gatherers In Southeastern Montana, Joseph Shawn Hamilton
Graduate Student Theses, Dissertations, & Professional Papers
Bison hunting has long been recognized as a key element of the lifeways of American Indians of the Northwestern Plains. Bison served as an integral component for food, shelter, tools, and clothing. It is no surprise that the importance bison hunting, as a socioeconomic institution, is revealed in the archaeological record of this region. A study of the material culture, most often lithic tools, found at prehistoric bison kills and processing sites allows archaeologists to draw inferences about the technology associated with the procurement of such vital animals. An investigation of bison jump, trap or pound lithic assemblage can provide …

Graduate Student Theses, Dissertations, & Professional Papers
The Montana Critical Infrastructure GIS Committee, on behalf of the Montana Department of Administration, has been involved for several years in concentrated efforts to make various types of map products available to those involved in emergency management throughout the state. As a component of this process, the Committee authorized funding for a project devoted to the development of standardized map products for pre-disaster mitigation (PDM) plans during the spring of 2006, and the research was completed later that year. The requirement for the development of these plans was established by the Disaster Mitigation Act of 2000. In Montana, implementation of …
Chronic Low-Level Lead Exposure Affects The Monoaminergic System In The Mouse Superior Olivary Complex, Tyler John Fortune
Chronic Low-Level Lead Exposure Affects The Monoaminergic System In The Mouse Superior Olivary Complex, Tyler John Fortune
Graduate Student Theses, Dissertations, & Professional Papers
Low-level lead (Pb) exposure is associated with behavioral and cognitive dysfunction. It is not clear how Pb produces these behavioral changes but low-level Pb exposure and learning disabilities have been associated with altered auditory temporal processing in both humans and animals. Temporal processing is used to decode complex sounds and to detect a signal within a noise background, and it is thought that neurons of the superior olivary complex (SOC) in the brainstem play a role in sound detection in noisy environments and in selective auditory attention. The SOC receives a catecholaminergic and a serotonergic innervation from the locus coeruleus …
Lithologic And Hydrogeologic Controls On The Occurrence, Transport, And Fate Of Mtbe In Fine Grained Glacial-Lacustrine Sediments, Mary Kathryn Sutherland
Lithologic And Hydrogeologic Controls On The Occurrence, Transport, And Fate Of Mtbe In Fine Grained Glacial-Lacustrine Sediments, Mary Kathryn Sutherland
Graduate Student Theses, Dissertations, & Professional Papers
In April of 1994, a leaking 60,480L gasoline underground storage tank was removed from George’s Conoco in Ronan, Montana. Investigations discovered a free product plume extending under Highway 93, with dissolved phase contamination (including MTBE) extending 460 m west to Spring Creek. Though geochemical sampling has established the general plume extent, the influence of aquifer heterogeneities on plume position and transport behavior is poorly described. The purpose of this work is to characterize the physical controls on plume migration. In addition to standard well installation and geochemical sampling, geotechnical tools including cone penetration testing (CPT) and Membrane Interface Probe (MIP), …

The Effective Viscosity Of Ash-Laden Flows, Kirstin Anne Burns
The Effective Viscosity Of Ash-Laden Flows, Kirstin Anne Burns
Graduate Student Theses, Dissertations, & Professional Papers
Debris flows can drastically alter ecosystems and damage infrastructure, and there is an increased risk of debris flows following a wildfire. In general, runoff and erosion drastically increase following a wildfire as a result of many processes, one of them being debris flows. Large debris flows are common in the months and years after wildfire in mountainous areas throughout the western U.S.A. The progressive bulking of surface runoff may be the dominant triggering mechanism of these debris flows. Vegetative ash on the hillslope becomes entrained in the flow, along with other fine-grained sediment and increases the effective viscosity of the …

Action-Oriented Sustainable Agriculture Education: Attitudes Towards Nutrition And Agricultural Practices In Guaimaca, Honduras, Sarah Lynne Potenza
Graduate Student Theses, Dissertations, & Professional Papers
Agricultural policies and global economic forces negatively affect many small-scale farmers in developing countries, resulting in widespread micronutrient malnutrition and environmental degradation. This study explores the connections between these issues, and the efficacy of using participatory education on sustainable agriculture to address them at a local level. Specifically, it evaluates an action-oriented education and sustainable agriculture program in Honduras, from the perspective of the participants and my own participation, as a means to improve agricultural practices and rural nutrition among subsistence farmers. As in many developing countries, access to land, poor soil conditions, steep hillsides, adverse climatic conditions, and limited …
First-Year Growth And Survival Of Habitat Revegetation Trials On The Lower Colorado River, Mexico, Stephen Dwight Handler
First-Year Growth And Survival Of Habitat Revegetation Trials On The Lower Colorado River, Mexico, Stephen Dwight Handler
Graduate Student Theses, Dissertations, & Professional Papers
Sweeping changes across the Colorado River watershed in the 20th century resulted in near-complete collapse of the natural communities in the Colorado River Delta (CRD) in Mexico. A brief return of freshwater flows in the 1980s and 1990s showed the riparian corridor remains resilient to past damage, and the CRD remains a vital area for habitat conservation and restoration. This project aimed to test conclusions drawn from similar projects in the United States and show that revegetation projects are possible along the lower Colorado River in Mexico. From November 2006 to October 2007, we tested the effects of various treatments …
Effects Of Seed Dispersal By Gibbons, Sambar, And Muntjac On Choerospondias Axillaris Demography, And The Disruption Of This Mutualism By Wildlife Poaching, Jedediah Farrell Brodie
Effects Of Seed Dispersal By Gibbons, Sambar, And Muntjac On Choerospondias Axillaris Demography, And The Disruption Of This Mutualism By Wildlife Poaching, Jedediah Farrell Brodie
Graduate Student Theses, Dissertations, & Professional Papers
Rampant illegal hunting threatens wildlife populations inside many tropical protected areas, compromising their long-term effectiveness. A critical question concerns whether such harvest has indirect effects on non-hunted organisms that interact with the game species. For example many tree species are demographically reliant on seed dispersal by vertebrates that are threatened by hunting; the anthropogenic disruption of this animal-plant mutualism can severely alter the composition of tropical forests. Here I show that illegal poaching has reduced or extirpated several mammal species from national parks in northern Thailand. This, in turn, has negatively affected the demography of the canopy tree Choerospondias axillaris, …
Hormonal Mediation Of A Unique Behavioral Polymorphism In The White-Throated Sparrow (Zonotrichia Albicollis), Meredith Bettencourt Swett
Hormonal Mediation Of A Unique Behavioral Polymorphism In The White-Throated Sparrow (Zonotrichia Albicollis), Meredith Bettencourt Swett
Graduate Student Theses, Dissertations, & Professional Papers
In this body of work, I examine how testosterone (T) physiology mediates the life-history trade-off between mating effort and parental care in the White-throated Sparrow. This species exhibits a behavioral polymorphism that occurs in both sexes. White-striped (WS) morphs are more territorially aggressive, sing more frequently and seek more extra-pair copulations. Tan-striped (TS) morphs provision nestlings more frequently. Thus this species roughly illustrates the trade-off between mating effort and parental care. I examine T physiology on three levels: plasma titres, binding globulins and response to the social environment. I ask whether levels of T correlate with morph-specific behavior and does …
The Importance And Seasonal Variation Of Terrestrial Invertebrates As Prey For Juvenile Salmonids On The Kol River Floodplain, Kamchatka, Russian Federation, Lorri Eberle
Graduate Student Theses, Dissertations, & Professional Papers
Eberle, Lorri C., M.S., Spring 2007 Biological Science The Importance and Seasonal Variation of Terrestrial Invertebrates as Prey for Juvenile Salmonids on the Kol River Floodplain, Kamchatka, Russia Committee Chair: Dr. Jack Stanford Fluxes of energy and resources from one system to another across an interface can play a major role in the structure and function of the food web of the receiving system. Floodplain spring brooks have a particularly high interface value and host high densities of juvenile fish likely seeking refuge from predators, high velocity water, and stressful temperatures. We propose that one potential reason that these systems …
The Influence Of Neighborhood, Family, School, And Student Dimensions Of Social Capital On Academic Achievement: An Integrated Theoretical Framework, Floy O. Scott
Graduate Student Theses, Dissertations, & Professional Papers
Current federal education law places the responsibility of the academic achievement of students with schools while ignoring other social factors that might influence the educational outcomes of students. Students are part of a complex social system that both enable and constrain their development and behavior. If we are to look at ways to improve academic programs, it is imperative we examine the different social systems to which students are exposed, including neighborhood, family, peer groups, and educational systems, in order to understand their role in assessing school accountability efforts. This study uses an integrated framework of social disorganization theory and …

Self-Control Choices Using Running Reinforcement, Jennifer Lynn Brinegar
Self-Control Choices Using Running Reinforcement, Jennifer Lynn Brinegar
Graduate Student Theses, Dissertations, & Professional Papers
Rats were given a choice between two amounts of a run-reward after responding on one of two equidistant levers. Responding on one lever resulted in the delivery of a smaller, immediate access to a running wheel (Impulsive) while responding on the other lever resulted in the delivery of larger but delayed access to a running wheel (Self-control). A variable inter-trial-interval was used to control the session duration regardless of the distribution of choices made by the subject. The results demonstrate that the use of a wheel-running reinforcer results in a significant self-control choice bias. This suggests that the use of …
Sex And Diversity In The Invasive Plant Hieracium Aurantiacum, Eli Stuart Loomis
Sex And Diversity In The Invasive Plant Hieracium Aurantiacum, Eli Stuart Loomis
Graduate Student Theses, Dissertations, & Professional Papers
Sexual reproduction is generally thought to provide long-term fitness advantages over asexual reproduction in the form of increased genetic diversity. Some work, however, suggests that asexual reproduction can also be advantageous. One situation when asexual reproduction provides an advantage is when colonizing a new range (Baker’s law), as in plant invasions. This study investigated the population structure of the invasive plant Hieracium aurantiacum. H. aurantiacum is an apomict – producing much of its seed asexually – and has become a common invasive in North America and New Zealand. The genetic diversity of H. aurantiacum was assessed over its invasive ranges …
Small Robe Band Of Blackfeet: Ethnogenesis By Social And Religious Transformation, Linda Matt Juneau
Small Robe Band Of Blackfeet: Ethnogenesis By Social And Religious Transformation, Linda Matt Juneau
Graduate Student Theses, Dissertations, & Professional Papers
One of the most significant challenges facing Native Americans and their indigenous identity is a greater understanding of the historical complexity of relationships that interconnected ethnically diverse populations across geographic landscapes. This thesis examines the range of Blackfoot political, social, economic structures, spiritual beliefs, and practices that were in place at the time of Euro-American contact. I use historically documented evidence of transformations that took place from the beginning of the fur trade era through the reservation era. Through the theoretical lens of ethnogenesis I use a case study of the Small Robe (Inuck’siks) band of the South Piegan of …
Spatial And Temporal Relationships Of Adult Male Black Bears To Roads In Northwest Montana, 2003-2004, Tonya Chilton-Radandt
Spatial And Temporal Relationships Of Adult Male Black Bears To Roads In Northwest Montana, 2003-2004, Tonya Chilton-Radandt
Graduate Student Theses, Dissertations, & Professional Papers
Chilton-Radandt, Tonya. M.S., Autumn 2006 Spatial and Temporal Relationships of Adult Male Black Bears to Roads in Northwest Montana Chairperson: Dr. Elizabeth Crone Roads have direct and indirect consequences for wildlife. Vehicle collisions are a direct cost of roads on wildlife. Indirectly, roads may increase mortality of game species by increasing hunting pressure along these roads. Adult male black bears (Ursus americanus) are the most desirable age and sex class to many hunters, which may lead to over-harvest of this sex and age class. Road closures (permanently closing or seasonally restricting roads) are used to mitigate impacts of roads on …
Habitat Use And The Effects Of Disturbance On Wintering Birds Using Riparian Habitats In Sonora, Mexico, Jose Fernando Villasenor
Habitat Use And The Effects Of Disturbance On Wintering Birds Using Riparian Habitats In Sonora, Mexico, Jose Fernando Villasenor
Graduate Student Theses, Dissertations, & Professional Papers
Riparian systems are important for breeding bird communities and are highly used as migratory corridors; however, their importance for wintering birds has not been assessed systematically. In order to assess the value of riparian areas for birds wintering in Sonora, data from 1,816 standard point counts were collected from 87 locations during January and February 2004-2006. A total of 253 species were detected across 14 vegetation types, including nine categories of riparian vegetation. The mean number of species and individuals detected per count was significantly higher in riparian vegetation than in non-riparian vegetation for migratory species, but not for residents. …
Biogeochemical Consequences Of Rapid Microbial Turnover And Seasonal Succession In Soil, S. K. Schmidt, E. K. Costello, D. R. Nemergut, Cory C. Cleveland, S. C. Reed, M. N. Weintraub, A. F. Meyer, A. M. Martin
Biogeochemical Consequences Of Rapid Microbial Turnover And Seasonal Succession In Soil, S. K. Schmidt, E. K. Costello, D. R. Nemergut, Cory C. Cleveland, S. C. Reed, M. N. Weintraub, A. F. Meyer, A. M. Martin
Ecosystem and Conservation Sciences Faculty Publications
Soil microbial communities have the metabolic and genetic capability to adapt to changing environmental conditions on very short time scales. In this paper we combine biogeochemical and molecular approaches to reveal this potential, showing that microbial biomass can turn over on time scales of days to months in soil, resulting in a succession of microbial communities over the course of a year. This new understanding of the year-round turnover and succession of microbial communities allows us for the first time to propose a temporally explicit N cycle that provides mechanistic hypotheses to explain both the loss and retention of dissolved …

Northern ecosystems contain much of the global reservoir of terrestrial carbon that is potentially reactive in the context of near-term climate change. Annual variability and recent trends in vegetation productivity across Alaska and northwest Canada were assessed using a satellite remote sensing–based production efficiency model and prognostic simulations of the terrestrial carbon cycle from the Terrestrial Ecosystem Model (TEM) and BIOME–BGC (BioGeoChemical Cycles) model. Evidence of a small, but widespread, positive trend in vegetation gross and net primary production (GPP and NPP) is found for the region from 1982 to 2000, coinciding with summer warming of more than 1.8°C and …
