Decadal Scale Responses Of Soil And Ecosystem Processes To Forest Restoration In Rocky Mountain Conifer Forests, Peter Ganzlin

Graduate Student Theses, Dissertations, & Professional Papers

Decades of fire suppression have left much of the forest in the intermountain western United States exceedingly dense, and forest restoration techniques – including thinning and prescribed fire – are increasingly being used in an attempt to mitigate the potentially disastrous effects of severe wildfire, to enhance tree growth and regeneration, and to stimulate soil nutrient cycling. While many of the short-term effects of forest restoration have been established, the long-term effects on soil biogeochemical and ecosystem processes are largely unknown. In this thesis I present two manuscripts documenting and synthesizing these long-term impacts. The first chapter focuses on the …

The Evolution Of Nutritional Co-Endosymbionts In Cicadas, James Theodore Van Leuven

Graduate Student Theses, Dissertations, & Professional Papers

Symbiosis occurs between organisms in all domains of life. The evolution of obligate symbionts from free-living bacteria typically results in the loss of genes involved in metabolic independence and an overall reduction in genome size. Outside the organelles, the most extreme examples of genome reduction come from the intracellular symbionts of sap-feeding insects. The genomes of these bacteria encode very few genes other than those involved in translation, replication, and amino acid synthesis. Candidatus Hodgkinia cicadicola (Hodgkinia) and Candidatus Sulcia muelleri (Sulcia) live in specialized insect cells (bacteriocytes) of the cicada Diceroprocta semicincta, and have undergone severe gene loss. Hodgkinia …

Factors Affecting Plant Responses To Arbuscular Mycorrhizal Fungi And Soil Fungal Communities, Lauren Priestman Waller

Graduate Student Theses, Dissertations, & Professional Papers

Arbuscular mycorrhizal (AM) fungi are ancient mutualists that associate with the majority of plants. However, the factors that influence how much a plant benefits from AM fungi, or the factors that influence other root-associated fungi are unclear. I examined how plant traits related to nutrient availability can explain variation in AMresponsiveness and whether native species differ from exotics in these relationships. Leaf mass per unit of area (LMA) correlated positively with mycorrhizal growth responsiveness (MGR) and root colonization (RC) among native species. This indicates that native species with more conservative traits more strongly benefit, and benefit from, AM fungi. Furthermore, …

The Role Of Dksa In The Stringent Response In The Lyme Disease Spirochete Borrelia Burgdorferi, Britney Cheff

Graduate Student Theses, Dissertations, & Professional Papers

Borrelia burgdorferi, the bacterium that causes Lyme disease, is maintained in nature through an enzootic cycle that includes a tick vector and a vertebrate host. The bacterium is acquired by an Ixodes tick from an infected vertebrate. The bacterium alters its gene expression to adapt to different environments of the tick and vertebrate. Between tick feedings, B. burgdorferi must contend with nutrient stress. The stringent response is a physiological mechanism when bacteria switch from “thriving” to “surviving” mode in response to limited nutrient resources; it is mediated by an increase in the nucleotide alarmone guanosine penta- or tetraphosphate, abbreviated …

Rural Food Procurement Strategies And Attitudes Towards Food Sourcing: A Case Study Of Boulder Town, Utah, Jane R. Philips

Graduate Student Theses, Dissertations, & Professional Papers

Today, while the United States continues to boast one of the highest standards of living in the world, rural communities suffer from an inability to acquire sufficient healthy food. Rural food systems have undergone a substantial transition over the last 50 years causing previously agricultural regions to now depend heavily on outside food sources. It should not be so hard to consume food produced within these rural communities, yet it is.

Researchers relying on secondary data analysis from national scale databases may identify rural areas as “low food access,” however, gaps in available records inhibit the development of a full …

Dna Methylation In Humans And Dogs: Evaluating The Impact Of Nutritional And Particulate Exposures, Luke Benjamin Montrose

Graduate Student Theses, Dissertations, & Professional Papers

Asthma is among the most common chronic diseases in children, among the leading causes of hospitalization for children, and one of the leading causes of school absenteeism. Discovery of preventable factors and the underlying mechanisms that exacerbate asthma among prevalent cases is important for mitigating the health burden of this childhood disease. Environmental factors such as exposure to particulate matter (PM) or nutritional deficiencies can lead to poor respiratory health among susceptible children. Recent animal studies suggest that PM exposures and dietary nutrients may influence asthma pathways through epigenetic mechanisms. Epigenetic modifications are heritable changes that can regulate gene activity …

Speaking For You: Positions Of Montana Ranching Organizations On Beef Market Concentration, Katie Marie Leblanc

Graduate Student Theses, Dissertations, & Professional Papers

Beef market concentration continues to be a highly contentious issue; especially in the culture-­‐rich ranching industry of Montana. The agriculture industry, specifically the beef sector, has experienced a tremendous amount of integration and consolidation over the past 50 years. This amount of industry restructuring has crafted a beef backgrounding and processing sector with the highest rates of concentration ever witnessed, with a Concentration Ratio (CR4) reaching nearly 82%. This research aims to qualitatively investigate ranching organizational positions, on the topic of beef market concentration and potential impacts this has had on the organization and their members who are located and …

Developing Microbial Biomarkers To Non-Invasively Assess Health In Wild Elk (Cervus Canadensis) Populations, Samuel B. Pannoni

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The composition of the intestinal bacterial community (intestinal microbiome) of mammals is associated with changes in diet, stress, disease and physical condition of the animal. The relationship between health and the microbiome has been extensively demonstrated in studies of humans and mice; this provides strong support for its potential utility in wildlife. When managing elk (Cervus canadensis), federal and state agencies currently must rely on invasive sampling and coarse demographic data on which to base their decisions. By developing microbiome-based biomarkers that vary as a function of elk body condition and disease (i.e. microbial biomarkers), we hope to …

Ecological Status Of Black-Tailed Prairie Dogs On Boulder, Colorado Open Space And Mountain Parks Land: An Analysis Of Select Indicators, Rachel A. Caldwell

Graduate Student Theses, Dissertations, & Professional Papers

Black-tailed prairie dogs (Cynomys ludovicianus) are ecosystem regulators, significantly influencing the surrounding ecosystem. On Boulder County, Colorado Open Space and Mountain Parks land, and throughout their range, prairie dogs affect a number of ecological functions including plant dynamics and associated animals. The ability of prairie dogs to promote the wellbeing of associated plant and animal species depends on the condition of prairie dog populations. One way to evaluate the current condition of prairie dogs and predict their future impact on the ecosystem is to evaluate the status of prairie dogs in relation to specific indicators. I address the …

An Analysis Of Socioeconomic Influences On Health Care Seeking Behavior In Humla, Nepal, Hannah Kuehl

Graduate Student Theses, Dissertations, & Professional Papers

Mobile medical camps (MMCs) are common in Nepal, as well as other parts of the world. MMCs in Nepal provide health care resources that are not available through the government health system, due to Nepal’s weak health infrastructure. Although MMCs are problematic for a variety of reasons, they continue to play a role in health care delivery in remote settings the world over. Despite the fact that MMCs are increasingly common in many countries around the world, their patient populations and their health outcomes are poorly understood. This thesis is an analysis of socioeconomic influences within a select group of …

Diabesties: How Diabetic Support On Campus Can Alleviate Diabetic Burnout, Kassandra E. Martin

Graduate Student Theses, Dissertations, & Professional Papers

The purpose of this study is to determine what types of supportive communication Type One diabetic students need when entering college to decrease diabetic related distress. A training program for students living with Type One Diabetes was created on the barriers they face to effective disease management on campus. This training plan was developed using Beebe, Mottet, and Roach’s (2013) Needs-Centered Training Model. The main issue that appeared from the Needs Assessment was that students are feeling high distress when it comes to keeping with a strict medical regimen. What they expressed interest in was a need for information from …

Coenzyme Q10, Sean M. Blumhardt

Graduate Student Theses, Dissertations, & Professional Papers

Blumhardt, Sean, M.A., May 2015, Exercise Science

Coenzyme Q10

Committee Chair: Dr. Steven Gaskill

Coenzyme Q10 (CoQ10) is a strong antioxidant and a key component of energy production in the electron transport chain. CoQ10 levels decrease with both age and cardiac disease in plasma and myocardium. After plasma CoQ10 concentrations decrease, dietary changes are generally unable to reestablish normal levels. CoQ10 supplementation is an inexpensive and safe therapy is able to reduce or prevent damage to cell membranes and vasculature by buffering reactive oxidative species. CoQ10 supplementation can decrease blood pressure in hypertensive patients as well as increase cardiac function …

"Horses And Oil In His Blood": Mythopoetics And Western Petromelancholia In Alexandra Fuller's The Legend Of Colton H. Bryant, Lindsay Stephens

Graduate Student Theses, Dissertations, & Professional Papers

Alexandra Fuller’s book The Legend of Colton H. Bryant, often read as merely a sad biography of a young man who meets his demise in the Wyoming energy patch, performs urgent cultural work. Fuller captures Wyoming’s shift from conventional (Easy Oil) extraction to the extreme (Tough Oil) extraction method known as hydraulic fracturing, or fracking, at the dawn of the twenty-first century. This shift to Tough Oil involves far more than engineering concerns, as Stephanie LeMenager points out in her cultural critique Living Oil. LeMenager terms our national failure to acknowledge the crises that accompany Tough Oil practices …
