Food Spoilage In Beeswax Impregnated Cotton Cloth Wraps Compared To Standard Storage Methods, Dawn E. Beck, Kevin M. Lane, Christine A. Shiel, Karl F. Welke

Beekeeping Certificate Program

Beeswax food wraps have gained popularity as a sustainable, natural alternative to single use options such as plastic bags, plastic wrap, and wax paper. Despite limited evidence, sellers advertise beeswax wraps as having antimicrobial benefits that help food stay fresh longer. The purpose of this investigation was to determine the ability of beeswax impregnated cotton cloth to inhibit food spoilage relative to traditional methods. We designed a prospective trial in which strawberry, bread, and cheese specimens were wrapped in one of the 3 materials: 1) beeswax impregnated cotton cloth, 2) wax paper, or 3) plastic bags alone and followed for …

Supplemental Ascorbate Diminishes Dna Damage Yet Depletes Glutathione And Increases Acute Liver Failure In A Mouse Model Of Hepatic Antioxidant System Disruption, Colin G. Miller, Jean A. Kundert, Justin R. Prigge, Julie A. Amato, Allison E. Perez, Lucia Coppo, Gabrielle N. Rizzo, Michael P. Kavanaugh, David J. Orlicky, Colin T. Shearn, Edward E. Schmidt

Biomedical and Pharmaceutical Sciences Faculty Publications

Cellular oxidants are primarily managed by the thioredoxin reductase-1 (TrxR1)- and glutathione reductase (Gsr)-driven antioxidant systems. In mice having hepatocyte-specific codisruption of TrxR1 and Gsr (TrxR1/Gsr-null livers), methionine catabolism sustains hepatic levels of reduced glutathione (GSH). Although most mice with TrxR1/Gsr-null livers exhibit long-term survival, ~25% die from spontaneous liver failure between 4- and 7-weeks of age. Here we tested whether liver failure was ameliorated by ascorbate supplementation. Following ascorbate, dehydroascorbate, or mock treatment, we assessed survival, liver histology, or hepatic redox markers including GSH and GSSG, redox enzyme activities, and oxidative damage markers. Unexpectedly, rather than providing protection, ascorbate …

Controls On No3-N Dynamics In The Upper Clark Fork River, Montana, Jacob Anthony Prater

Graduate Student Theses, Dissertations, & Professional Papers

Studies relating ecosystem energetics to nutrient uptake in streams have generally found respiration to be a more dominant control on nutrient dynamics relative to primary production due to light limitation in most low-order systems. In this study, I measured biomass, hydrology, metabolism, and dissolved solutes in an open-canopy mid-order river located in western MT. Daily stream metabolism was modeled using a modified single-station, open-channel method, and measures of dissolved solutes were evaluated at both local and reach scales to examine how point-measures and those integrated through space represent biogeochemical behavior. Metabolic rates and standing stocks of benthic organic matter were …

Exploring Indigenous Involvement In The Fur Trade At The Bridge River Pithouse Village, British Columbia, Rebekah Jean Engelland

Graduate Student Theses, Dissertations, & Professional Papers

Much research has been done on the Fur Trade period occupation of Housepit 54 at the Bridge River site. This thesis investigates the cause of resource intensification seen in the increase in projectile points, faunal remains, hide scrapers, and fire-cracked rock (FCR). In order to determine the impetus of this change, I compare the fracture patterns of FCR, the size of FCR, the densities of FCR, deer NISP, and slate scrapers, and the population estimate from the fur trade floor and roof to the last floor and roof of the previous occupation. This will determine whether the resource intensification was …

Nutritional Access And Resource Knowledge In College, Darra Perdaems

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Nearly 20% of college students are food insecure, compared to 14.5% of the general population who face food insecurity. Factors that influence this include rising tuition costs, lack of affordable housing in college towns, and an increase in first-generation and/or low-income students. Moreover, food insecurity has a notable effect on physical and mental health and overall academic performance. College years are an important intervention time for nutritional practices as students are making sovereign choices and assuming responsibility for their health decisions that will ultimately shape their lifestyles. We conducted focus groups with UM college students to gauge their dietary habits …

Promoting Physical Activity Among American Indian Older Adults, Maja R. Pedersen

Graduate Student Theses, Dissertations, & Professional Papers

Background: Physical activity (PA) promotion is acknowledged as a critical component to improve public health among the growing population of older adults in the U.S. American Indian and Alaska Native (AIAN) older adults experience disproportionately high rates of chronic disease and disability compared with non-Hispanic White peers, and demonstrate lower levels of PA, indicating a need for examination of unique factors influencing their PA behavior.

Purpose: This study revealed the current state of PA intervention research among AIAN older adults in the U.S. and utilized best practices to identify factors that can influence the development, adaptation, and implementation of PA …

The Place Of Community Food Forests: A Review And Case Study Of Community Food Forests And Their Untapped Potential, Sarah Eiden

Graduate Student Theses, Dissertations, & Professional Papers

As population grows, the borders of urban and peri-urban areas continue to expand. The UN projects that by 2050 more than 68% of the world population is expected to live in urban areas (UN, 2018). Presently, urban centers are heterotrophic, or highly consumptive of products produced elsewhere, making them one of the most pressing challenges to global sustainability (Wu, 2008). With an ever-increasing imperative for more sustainable food production, multi-use edible green landscapes and other autotrophic, or self-feeding urban agriculture initiatives, are gaining attention and creative practice to incorporate a diversity of ecosystem services (ES). Community food forests (CFF) are …

Ungulates Search For The Ideal Home: How Predation And Forage Differentially Affect Males And Females In A Partially Migratory Population, Hans William Martin

Graduate Student Theses, Dissertations, & Professional Papers

Migration is a strategy used across taxa to access resources in temporally heterogenous landscapes. Migratory species can attain higher abundances because access to higher quality resources, and/or reduction in predation risk. However, most migratory species occur in partially migratory populations, a mix of migratory and non-migratory, resident individuals. I first investigate the potential mechanisms maintaining partial migration in a partially migratory elk (Cervus canadensis) population. I test whether the theory of Ideal Free Distribution (IFD) can explain the coexistence of different migratory tactics in a partially migratory population. IFD predicts that individuals exhibit density-dependent vital rates and should select different …

A Comprehensive Forensic Case Report For The Bonner County Coroner Case #20-100, Megan Copeland

Graduate Student Theses, Dissertations, & Professional Papers

This report consists of an inventory of the skeletal remains of case #20-100, assessment of the minimum number of individuals (MNI), a biological profile if possible, and a literature review of ­­­the use of DNA in ancestry estimations. The skeletal remains are consistent with an MNI of one. The remains are likely from a male individual, and skeletal features display a mixture of European and Asian characteristics. The individual is estimated to be between of 25-35 years old with an estimated stature of between 5’1” and 5’6”.

Estimating Wolf Predation Metrics, Patterns, And Dynamics Across Time And Space In The Multi-Prey System Of Yellowstone National Park, Matthew Caldwell Metz

Graduate Student Theses, Dissertations, & Professional Papers

Predation is a fundamental driver in ecology, structuring ecosystems across the globe. However, understanding the effects of large carnivore predation is limited by both the observation process and the shorter duration of many studies. I used data from 23 years in Yellowstone National Park to disentangle both the importance of wolf predation on prey, and the imperfect observation process of studying predation. I first used field observations to test whether a sexually-selected trait, antlers in male elk, deterred wolf predation. I found that antlers reduced predation risk, emphasizing the selective nature of predation. Next, I used GPS data and ground-based …

Adapting Sustenance: Indigenous People Preserve Traditional Food Sources, Mary Katherine Auld

Graduate Student Portfolios, Professional Papers, and Capstone Projects

Traditional foodways of Indigenous people around the world are being changed by human-caused climate change, environmental policy, and land management. For Indigenous people in interior Alaska and Montana, culture and survival are tied tightly to hunted and gathered food. The average American gets their food from a grocery store and thus is somewhat insulated from the impact of climate change on their diet. But climate change has its hand directly in the pantries, dinner plates, and seasonal practices of Indigenous people. I believe food is a central way people are tied to the earth, and thus creating narratives about impacts …

Adult Perspectives Of Kaleidoscope Connect: A Social Emotional Program Aimed At Promoting Resilience Among Youth, Samantha Cody Russell

Graduate Student Theses, Dissertations, & Professional Papers

Purpose. The current study explored the perspectives of adults who participate in Kaleidoscope Connect, and specifically, to understand how effective adults perceive the program in its attempt to promote resilience, school safety, and the psychological well-being of youth.

Background. Youth who encounter stressful life circumstances or experience trauma often experience negative life outcomes, such as lower academic achievement, mental illness, and perpetrating violence (Liu, Reed & Girard, 2016). Research, however, has demonstrated that some youth who have these experiences have more positive outcomes, including psychological health, strong academic achievement, and financial stability (Zolkoski & Bullock, 2012). Resilience is a dynamic …

Promoting Well-Being Among College Students: The Effects Of A Positive Psychology Course, Daniel Jm Salois

Graduate Student Theses, Dissertations, & Professional Papers

College students report high rates of mental distress, including depression, high stress, anxiety, lack of social support, and physical ailments. College campuses use a variety of approaches to address the well-being of students. However, existing interventions have mixed results and do not always reach all students who may need mental health support. Positive psychology courses and positive psychology interventions have shown promise in promoting well-being. In this quantitative, quasi-experimental, pretest-posttest archival study, I examined the effects of a semester-long happiness and positive psychology course (COUN 195) on students’ well-being and mental health. This innovative happiness course included didactic lectures, small …

Linking Habitat, Populations And Policy For Caribou In The Face Of Increasing Disturbance, Eric Charles Palm

Graduate Student Theses, Dissertations, & Professional Papers

In North America’s boreal forest, wildfire has long been the dominant form of natural disturbance. However, the human footprint in the region is steadily growing. Large-scale forest harvest and energy development have fragmented late-successional forests, leading to habitat loss for species such as caribou (Rangifer tarandus) that rely on these ecological communities. Caribou have experienced widespread population declines and local extirpation throughout the western boreal forest in recent decades. I first analyzed caribou resource selection responses to fires in >685 female caribou across 15 populations that span a wide gradient of fire frequency but are exposed to relatively little human …

The Smell Of Attraction: Cuticular Hydrocarbon (Chc) Profiles In A Horned Beetle, Chelsey N. Caldwell

University of Montana Conference on Undergraduate Research (UMCUR)

The Asian Rhinoceros beetle, Trypoxylus dichotomus, is characterized by its large “pitchfork” horns on the heads of males. They use these horns to engage in male competition; battling each other for access to limited females. However, recent field studies suggest that females are choosy, selecting male mates based on traits other than horn size. In many insects, cuticular hydrocarbons are used by females to choose attractive, high quality males as mating partners. CHC’s are the molecules present in the waxy outer layer of the cuticle, functioning in waterproofing but also acting as pheromones. Individual CHC profiles can be indicative of …

Investigating Childhood Stunting And Malnutrition Outcomes In Sukadana And Simpang Hilir, Indonesia, Julia Goar

UM Graduate Student Research Conference (GradCon)

Best of GradCon Award Winner: Poster Presentations - Humanities and Social Sciences

Purpose: Infant and child growth is understood as an important indicator of nutritional status and health in populations. Stunting, wasting, and being underweight are the indicators used to measure child growth and reflect nutritional imbalance resulting in undernutrition. The World Health Organization has cited Indonesia as one of five countries that have child stunting higher than both the regional and global averages, making this a priority issue for the government as well as clinics across the country including Alam Sehat Lestari (ASRI) Clinic located in Sukadana, Borneo. The …
