Graduate Student Theses, Dissertations, & Professional Papers
ABSTRACT Carlson, Eric S., M.A., Spring 2010 Anthropology Subsistence Change and Emergent Social Inequality in an Early Complex Hunter-Gatherer Winter Village: A Zooarchaeological Assessment of the Bridge River Site (EeRl4), Middle Fraser B.C. Chairperson: Dr. Anna Marie Prentiss Analyses of faunal material from the 2008 excavations at the Bridge River Site (EeRl4) show that reliance on stored anadromous salmon (Oncorhynchus sp.) remains the primary food staple from early occupations of the village (1550bp) until its abandonment (1100bp), and indeed intensifies through time. Second, taxonomic diversity in food resources declines through time, signifying a diachronic process of resource specialization. The presence …

Summer Wolf Diet In Northwestern Montana, Jonathan Derbridge
Graduate Student Theses, Dissertations, & Professional Papers
Wolf (Canis lupus) diet can be estimated from undigested remains of prey in scats or through stable isotope analysis (SIA) of wolf hair when distinct δ13C and δ15N values of potential diet sources are known. Our objectives were to compare diet analysis methods, to estimate intra-population diet variability, and to determine proportions of prey consumed by wolves. We collected scats of 4 wolf packs in northwestern Montana from June to August 2008, and guard hairs of 45 wolves from 12 packs, May to August 2009. We calculated percent biomass consumed of deer (Odocoileus spp.), elk (Cervus canadensis), moose (Alces alces), …

Human-Black Bear Interactions In Missoula Montana, Jerod A. Merkle
Human-Black Bear Interactions In Missoula Montana, Jerod A. Merkle
Graduate Student Theses, Dissertations, & Professional Papers
The increasing frequency and distribution of human-wildlife interactions is a direct result of a growing human footprint worldwide. Specifically, the effects of urbanization can be significant for many species, including American black bears (Ursus americanus). Human-black bear interactions (HBI) resulting in property damage, injury or death to humans, or fear of injury or death to humans are increasing in number and extent throughout North America, and wildlife management agencies are interested in reversing this trend. Using a case study of HBI in Missoula, Montana, my objectives were to examine temporal patterns of human behaviors and attitudes regarding HBI, develop a …
Uncertainty Monitoring In Sprague-Dawley Rats (Rattus Norvegicus), Leslie Anne Angel
Uncertainty Monitoring In Sprague-Dawley Rats (Rattus Norvegicus), Leslie Anne Angel
Graduate Student Theses, Dissertations, & Professional Papers
Comparative psychologists have explored the metacognitive capabilities of rhesus monkeys, a capuchin monkey, an orangutan, a dolphin, pigeons, and rats. Previous research with rats has demonstrated inconsistent results (Foote & Crystal, 2007; Smith & Schull, 1989). In the current study, two Sprague-Dawley rats were tested in a tone-length discrimination task in which they were prompted to press one of two levers indicating "short" or "long" depending on the duration of a tone. They also had the option to opt out of some trials. If the subjects knew when they did not know the answer to the task, they were expected …
Are Black Bears Declining In Montana? Inference From Multiple Data Sources In The Face Of Uncertainty, Julie Ann Beston
Are Black Bears Declining In Montana? Inference From Multiple Data Sources In The Face Of Uncertainty, Julie Ann Beston
Graduate Student Theses, Dissertations, & Professional Papers
Carnivores are managed both to maintain populations and reduce conflict with humans, but data-based decision-making is difficult due to the expense of data collection. When new fieldwork is impossible, we can benefit from available data in assessing populations. I used demographic and harvest data to assess the population status of black bears (Ursus americanus) in Montana.
I conducted a hierarchical Bayesian meta-analysis of black bear demographic studies to evaluate geographic structuring and estimate vital rates and population growth rate. Adult survival is higher in the west than the east, but the reverse is true for fecundity. The mean …
Bending Gen(Re)Der: A Negotiation Of Identity Through Language In Helene Cixous And The Self, Marley Mckenna
Bending Gen(Re)Der: A Negotiation Of Identity Through Language In Helene Cixous And The Self, Marley Mckenna
Graduate Student Theses, Dissertations, & Professional Papers
Bending Gen(re)der: The Negotiation of Identity through Language in Hélène Cixous and the Self analyses the French author Hélène Cixous and her most recently published book, Love Itself in the Letterbox. The book cannot be said to fit into a specific genre but moves through a series of musings surrounding her personal history with France, New York, authors she has been influenced by, her relationship with mother, and most often the contemplation of her lover. Cixous’ use of ecriture feminine (women’s writing) layers the writing to create a playful, confusing, incongruent body of work in an attempt to subvert the …
Causes And Consequences Of Prolonged Dormancy: Why Stay Belowground?, Jennifer R. Gremer
Causes And Consequences Of Prolonged Dormancy: Why Stay Belowground?, Jennifer R. Gremer
Graduate Student Theses, Dissertations, & Professional Papers
Prolonged dormancy is a stage in which mature plants fail to resprout during the growing season and instead remain alive belowground. Though it is relatively common, the causes and consequences of this intriguing stage have remained elusive. In this dissertation, I investigate the causes and consequences of prolonged dormancy in a long lived perennial herb, Astragalus scaphoides.
First, I use a combination of demography and ecophysiology to study the proximate mechanisms associated with prolonged dormancy. Analysis of a long-term demographic dataset indicates that both endogenous factors (e.g. age, condition, and history) and exogenous factors (e.g. climate and spatial variation) are …

Post-Course Environmental Behavior Change Of Wild Rockies Field Institute Participants, Theodore Rosenberger Morrison
Graduate Student Theses, Dissertations, & Professional Papers
In light of the environmental crisis facing the world, the need for citizens to behave in an environmentally responsible manner is critical to finding lasting solutions. After conducting and analyzing 20 in-depth interviews with alumni of the Wild Rockies Field Institute (WRFI), this study found that despite elevated pre-course levels of environmentally responsible behavior most participants reported an increased level of post course environmental behavior change. Post-course impacts ranged from a change of, or further investment in academic and career goals, lifestyle choices, empowerment, ethical development and political activity. Participants reported these outcomes were influenced by a variety of course …

The Missoula Poplar Project: Utilizing Poplars To Enhance Wastewater Treatment, Heath Nicolas Carey
The Missoula Poplar Project: Utilizing Poplars To Enhance Wastewater Treatment, Heath Nicolas Carey
Graduate Student Theses, Dissertations, & Professional Papers
Wastewater treatment plants rank second to agricultural runoff in the top ten major pollution sources to U.S. surface waters. Such nutrient-rich inputs can degrade aquatic ecosystems by accelerating eutrophication events, especially in summer months when surface water flows are low. Alternative treatment practices, modeled after natural ecosystem processes, could reduce nutrient inputs to surface waters while accumulating biomass and sequestering atmospheric carbon dioxide. I designed and implemented an alternative treatment strategy, using effluent to fertilize trees at the Missoula Wastewater Treatment Facility. The objectives of this work were to assess: 1) environmental impacts of effluent application; 2) tree survivorship; and …

Graduate Student Theses, Dissertations, & Professional Papers
Evans, Heather, Master of Science, May 2010 The Biogeography of Ageratina adenophora: A Mexican Trans-Global Invader Co-Chairman: Dr. Jeffrey Gritzner Co-Chairman: Dr. Ragan Callaway Invasive plants are a global problem often resulting in negative impacts upon populations of native plants and the environments in which they grow. Invasive plants inhibit native species and take over areas where they have been introduced. These invasive species create ecological problems for wildlife foraging, as they often transform the vegetation of native habitats resulting in conditions unsuitable for grazing. In addition, invasive plant species pose problems for humans in the areas of health, economics, …
The Discipline Of Identity: Examining The Challenges Of Developing Interdisciplinary Identities Within The Science Disciplines, Nicholas Richard Burk
The Discipline Of Identity: Examining The Challenges Of Developing Interdisciplinary Identities Within The Science Disciplines, Nicholas Richard Burk
Graduate Student Theses, Dissertations, & Professional Papers
Conducting scientific research that integrates multiple disciplines is an increasingly important, and yet challenging endeavor. This study employs the construct of identity to characterize and examine the obstacles to successful interdisciplinary work. It is argued that identity provides a useful lens into the process of scientific investigation, because as a construct, it has been shown to influence the way one sees oneself, others, and the practice of “good science.” It is therefore assumed that scientists’ identities may be an under-examined, mitigating factor in whether they develop an interest and aptitude for interdisciplinary collaboration. This study qualitatively examines 20 postgraduate students …
The Effct Of Low-Level Lead On Serotonin Expression In The Developing Mouse Superior Olivary Complex And Somatosensory Cortex, Sunyoung Park
The Effct Of Low-Level Lead On Serotonin Expression In The Developing Mouse Superior Olivary Complex And Somatosensory Cortex, Sunyoung Park
Graduate Student Theses, Dissertations, & Professional Papers
Low-level Pb exposure is a risk factor for neurobehavioral and cognitive deficits in both humans and animals. These neurological dysfunctions have been associated with deficits in auditory temporal processing. The developing central nervous system is particularly susceptible to Pb exposure, and Pb decreases the immunoreactivity of serotonin (5-HT) and VMAT2 in the lateral superior olive (LSO). During early developmental, "non-serotonergic" sensory neurons, including LSO neurons and thalamocortical neurons of the somatosensory system, transiently take up 5-HT from the extracellular environment through the transient expression of the serotonin reuptake transporter SERT. Maintenance of appropriate 5-HT levels is important for development of …
Recommendations For Instream Flow Rights On National Forest Lands In Montana, Andrew Marias Fischer
Recommendations For Instream Flow Rights On National Forest Lands In Montana, Andrew Marias Fischer
Graduate Student Theses, Dissertations, & Professional Papers
A unique opportunity exists to create instream water rights on national forest lands in Montana as a result of the US Forest Service Reserved Water Rights Compact between the US Forest Service (USFS) and the state of Montana, which went into law in 2007. Instream water rights on national forest lands are important because they have the potential to protect streamflows that support many vital ecosystem functions in our forests from water development pressures. Montana Trout Unlimited has an interest in advancing and accelerating this effort by providing stream recommendations to the USFS for the establishment of future water rights. …

Scale And Source Of Geospatial Data For Wildfire Risk Assessments: Comparing National Data With Local Data In The Deschutes National Forest, Julie Marie Gilbertson-Day
Graduate Student Theses, Dissertations, & Professional Papers
Widespread use of geospatial data in environmental decision-making tools such as wildfire risk models has called attention to questions of availability, quality, and currency of input data layers. As wildfires are modeled with growing confidence and knowledge of how resources respond to fire is increasing, challenges must be addressed before geospatial data are acquired and used to represent resources of high value in wildfire risk assessments. Researchers at the Rocky Mountain Research Station and the Western Wildland Environmental Threat Assessment Center of the USDA Forest Service employ a framework for assessing wildfire risk to a range of human and ecological …

Population Dynamics Of The Columbia Spotted Frog (Rana Luteiventris): Inference From Long-Term Demography, Rebecca Marie Wahl Mccaffery
Graduate Student Theses, Dissertations, & Professional Papers
Worldwide extinctions of amphibians are at the forefront of the biodiversity crisis, with climate change figuring prominently as a potential driver of continued amphibian decline. Changes in both the mean and variability of climate conditions may affect amphibian populations in complex, unpredictable ways. However, few studies have evaluated effects of climate change on individual vital rates and subsequent population dynamics of amphibians. I investigated the population dynamics of a high elevation population of the Columbia spotted frog (Rana luteiventris) in relation to climate variation over a ten-year period.
I documented an increase in survival and breeding probability as severity of …
Assessing Macroinvertebrate Community Recovery In Post Restoration Silver Bow Creek, Montana, Sean Patrick Sullivan
Assessing Macroinvertebrate Community Recovery In Post Restoration Silver Bow Creek, Montana, Sean Patrick Sullivan
Graduate Student Theses, Dissertations, & Professional Papers
Since the turn of the twentieth century, mining activities have contaminated the floodplain and streambed of Silver Bow Creek, Montana, resulting in a streambed devoid of life and severely contaminated with heavy metals. In the mid nineteen seventies, up-stream water treatment facilities were upgraded and water quality improved, bringing benthic invertebrates back to reaches of Silver Bow Creek. The extent and concentration of toxicants in and around the streams of the Upper Clark Fork River Basin resulted in the designation of over 100 miles of river as Federal Superfund sites. Since 1999 reclamation and restoration efforts have been implemented on …
Analysis Of The University Of Montana Forensic Case 29, Daniel James Haak
Analysis Of The University Of Montana Forensic Case 29, Daniel James Haak
Graduate Student Theses, Dissertations, & Professional Papers
The application of non-metric forensic anthropological techniques produces results that are sometimes not always scientifically valid. Using the commonly accepted techniques to produce a biological profile (age, sex, ancestry, height, pathology and trauma), an application of the methods is utilized and critiqued in the analysis of The University of Montana forensic case 29 (UMFC 29). Using the accepted techniques in forensic anthropology, UMFC 29 was identified as a Black Male with an age range of 35-65 years and a height of 5’3’’-5’6’’. Possible skeletal trauma is found on the vertebral bodies, left 4th rib, and on the left scapula and …
Chinese Classifier Acquisition: Comparison Of L1 Child And L2 Adult Development, Jiang Song Gong
Chinese Classifier Acquisition: Comparison Of L1 Child And L2 Adult Development, Jiang Song Gong
Graduate Student Theses, Dissertations, & Professional Papers
The context of this thesis is the long-debated issue of whether or not adult second language (L2) development is basically similar to child first language (L1) development. The thesis approaches the issue through research dealing with L1 acquisition of Chinese classifiers and a pilot study of L2 adult classifier acquisition. First, evidence that children acquire specific classifiers earlier than measure classifiers is discussed and explained in light of existing language learning theories. With the aim of providing comparable data regarding L2 adult classifier acquisition a pilot study was conducted in which nine adult English-speaking learners of Chinese were tested on …
Evaluating Population Estimates Of Mountain Goats Based On Citizen Science, Jami J. Belt
Evaluating Population Estimates Of Mountain Goats Based On Citizen Science, Jami J. Belt
Graduate Student Theses, Dissertations, & Professional Papers
Citizen science programs that use trained volunteers may be a cost-effective method for monitoring wildlife at large spatial and temporal scales. However, few studies have compared inferences made from data collected by volunteers to professionally collected data. In Glacier National Park (GNP), Montana, I assessed whether citizen science is a useful method to monitor mountain goat (Oreamnos americanus) populations. I compared estimates of mountain goat abundance by volunteers at 32 sites throughout GNP to estimates by biologists and raw counts from aerial surveys at a subset of 25 and 11 sites, respectively. I used multiple observer surveys to calibrate the …
Factors That Influence Ponderosa Pine Duff Mound Consumption, Emily Claire Garlough
Factors That Influence Ponderosa Pine Duff Mound Consumption, Emily Claire Garlough
Graduate Student Theses, Dissertations, & Professional Papers
When applying prescribed fire to long-unburned but fire-dependent ecosystems managers require better decision-support models to determine appropriate conditions for achieving desired effects. Prolonged combustion in duff accumulations at the base of large conifers can lead to fine root mortality, cambial injury, enhanced susceptibility to bark beetle attack, and possibly tree death. Pre-burn sampling to predict duff mound consumption from measurable attributes is vital in order to limit the deleterious effects of prolonged smoldering combustion. The objective of this study was to determine the conditions that influence duff consumption and analyze the variability of these factors in the field. Duff moisture …
Hemin Acquisition In Bartonella Quintana, Nermi Lee Parrow
Hemin Acquisition In Bartonella Quintana, Nermi Lee Parrow
Graduate Student Theses, Dissertations, & Professional Papers
Bartonella quintana, a Gram-negative bacterial pathogen, causes Trench fever, bacillary angiomatosis and endocarditis. Transmitted by the human body louse (Pediculus humanus corporis), the agent has a tropism for erythrocytes in humans. In vitro growth requires an extraordinary concentration of hemin, and genomic analyses indicate several potential uptake systems and iron-responsive regulators. Transcription of the hbp genes (hemin binding protein genes) is responsive to alterations in available hemin and an HbpA homolog in B. henselae reportedly functions as a hemin receptor in E. coli hemA strain EB53. B. quintana hbpA was not able to complement EB53, indicating that …

Marine Applications Of An Autonomous Indicator-Based Ph Sensor, Sarah E. Cullison
Graduate Student Theses, Dissertations, & Professional Papers
Currently, the lack of accurate in situ pH measurements limits our understanding of natural pH variability. In order to predict future pH changes in the oceans, quality high temporal resolution pH data are needed. This work used the newly developed Submersible Autonomous Moored Instrument for pH (SAMI-pH), a fully autonomous, in situ spectrophotometric pH sensor, to study oceanic pH variability. The three main goals of this research were to: determine the field performance of the new SAMI-pH, establish the utility of combining SAMI-pH data with in situ pCO2 data to characterize the entire inorganic carbon cycle and establish pH variability, …
Masculine Domesticity In The Mining West: An Archaeological Investigation At Coloma Ghost Town, Margaret Anne Thurlo
Masculine Domesticity In The Mining West: An Archaeological Investigation At Coloma Ghost Town, Margaret Anne Thurlo
Graduate Student Theses, Dissertations, & Professional Papers
The recovery of a scorifier, or roasting dish, at Feature 131 in Coloma, Montana led to the theory that the feature represented an assayer’s household. Historical documentation, in the form of a personal diary, revealed that the assayer at Coloma, Chester Pray, shared a cabin with another man. This revelation led to a particular question: what would the material record of an all-male household look like? The majority of previous engendered investigations into 19th century households focused on the role of women. Gender is often equated with women in historical and archaeological studies, and it became necessary to integrate literature …

The Use Of Natural Product Substrates For The Synthesis Of Libraries Of Biologically Active, New Chemical Entities, Joshua Bryant Phillips
Graduate Student Theses, Dissertations, & Professional Papers
Since Alexander Fleming first noted the killing of a bacterial culture by a mold, antibiotics have revolutionized medicine, being able to treat, and often cure life-threatening illnesses and making surgical procedures possible by eliminating the possibility of opportunistic infection. However, during the past 30 years many of the infections that were once easily cured by the proper antibiotic are no longer so due to a precipitous rise in multi-drug resistant organisms. This rise in multi-drug resistant organisms poses a grave threat to the medical advances that have been made in the past century and underscores the need for new antibiotics. …

Bio/Organic Compound Detection Using Sodium Sulfate Minerals: Implications In The Search For Life On Mars And Europa, Charles Doc Richardson
Graduate Student Theses, Dissertations, & Professional Papers
With the discovery of Na-sulfate minerals (thenardite, mirabilite) on Mars and Europa, recent studies using these minerals have focused on their ability to assist in the detection of biosignatures. On Earth, biotic and biotic processes can assist in the formation and deposition of these minerals. A primary objective of these studies is the detection of bio/organic compounds that may be associated with the mineral. These biosignatures would imply biological involvement during mineral formation. The following research presents a series of natural and synthetic investigations to determine if biological activity is associated with Na-sulfate mineralization, and if these minerals can assist …
