Nutrition, Dietetics, and Food Sciences Faculty Publications

The broad ecological distribution of L. casei makes it an insightful subject for research on genome evolution and lifestyle adaptation. To explore evolutionary mechanisms that determine genomic diversity of L. casei, we performed comparative analysis of 17 L. casei genomes representing strains collected from dairy, plant, and human sources. Results Differences in L. casei genome inventory revealed an open pan-genome comprised of 1,715 core and 4,220 accessory genes. Extrapolation of pan-genome data indicates L. casei has a supragenome approximately 3.2 times larger than the average genome of individual strains. Evidence suggests horizontal gene transfer from other bacterial species, particularly lactobacilli, …

Hydrologic Efficiency In Water Conservation, L. Douglas James

Reports

Introduction: The hydrologic cycle can be subdivided into three phases: 1)Humidity is transported within the atmosphere and becomes precipitation, and 2) Water moves downhill until eventually reaching the sea while all the time 3) Evapotranspiration returns exposed moisture to the atmosphere. During its movement, flowing water transports suspended sediments and dissolved minerals to reshape landforms and redistribute the mineral composition of the earth's surface throughout geologic time. It is during the second phase that flowing water can be diverted for uses that generally add to evaportranspiration (through consumptive use) and transport (through waste disposal). The water resources development that serves …

Methodological Tools, Ethan P. White, Xiao Xiao, J. B. Nick, Richard M. Sibly

Biology Faculty Publications

Methodological approaches for comparing metabolic theory predictions to empirical data fall into two general categories: 1) determining if the general functional form of a relationship predicted by the theory is valid; and 2) determining whether the observed values of the parameters match the specific quantitative predictions made by the theory. Both of these categories of analysis rely on being able to accurately determine the best fitting form of a model with the same general functional form as that of MTE, so we will begin by discussing how this has typically been done using OLS regression on appropriately transformed data. Potential …

Investigating Human Impact In The Environment With Faded Scaffolded Inquiry Supported By Technologies, D. T. Longhurst, M. Longhurst, A. M. Duffy, Paul G. Wolf

Biology Faculty Publications

Teaching science as inquiry is advocated in all national science education documents and by leading science and science teaching organizations. In addition to teaching science as inquiry, we recognize that learning experiences need to connect to students’ lives. This article details how we use a sequence of faded scaffolded inquiry supported by technologies to engage students meaningfully in science connected to their lives and schoolyards. In this approach, more teacher guidance is provided earlier in the inquiry experiences before this is faded later in the sequence, as students are better prepared to complete successful inquiries. The sequence of inquiry experiences …

Changing Lives In A Semester: A Teaching Approach To Help With Tenure And Promotion While Providing An Experience They'll Never Forget, Roslynn Brain

Environment and Society Faculty Publications

Do all university courses have to be structured in a traditional way? For many, the answer is a resounding, NO! Generally, we assume a course needs to have a midterm, final and at least one major project. Although this may fit well with many standard courses, it can be a wonderful experience to deviate away from the norm and delve into the world of service learning.

Reuse: Creating A Next Life For Common Items, Roslynn Brain, H. Waldbillig

Environment and Society Faculty Publications

If you are looking for ways to save money and add creative flair to your daily life, reusing everyday items you are likely to throw away could be the answer! We produce an average of 4.4 pounds each of trash a day in the U.S., which amounts to 1,600 pounds per person each year (Environmental Protection Agency, 2011). This yearly waste produced by each one of us is more than the typical weight of a Bison, America’s largest land animal! Often overshadowed by recycling, reusing is a zero-impact technique for waste prevention. By using a product or item in its …

Achieving Development Impact Among Pastoral And Agro-Pastoral People: Lessons Learned In Southern Ethiopia, 2000-2009, D. Layne Coppock, Seyoum Tezera, Solomon Desta, Getachew Gebru

Environment and Society Faculty Publications

The outreach and action-research component of the Pastoral Risk Management (PARIMA) project began with a focus on the Borana Plateau of southern Ethiopia in 2000. Our goal was to use participatory methods to learn about development needs and apply the knowledge gained to benefit local communities. Today it is clear that the project has had positive impacts on the lives of thousands of people. This report helps tell this story by emphasizing the process we used.

At the start we knew that the traditional pastoral system was under intense pressure as poverty and hunger were common. Community-based problem diagnosis confirmed …

Concurrent Chains Schedules As A Method To Study Choice Between Alcohol Associated Conditioned Reinforcers, Corina Jimenez-Gomez, Timothy A. Shahan

Psychology Faculty Publications

An extensive body of research using concurrent-chains schedules of reinforcement has shown that choice for one of two differentially valued food-associated stimuli is dependent upon the overall temporal context in which those stimuli are embedded. The present experiments examined whether the concurrent chains procedure was useful for the study of behavior maintained by alcohol and alcohol-associated stimuli. In Experiment 1, rats responded on concurrent-chains schedules with equal variable-interval (VI) 10-s schedules in the initial links. Across conditions, fixed-interval schedules in the terminal links were varied to yield 1:1, 9:1, and 1:9 ratios of alcohol delivery. Initial-link response rates reflected changes …

Psychology Faculty Publications

With funding from the Kenneth A. Scott Charitable Trust, A KeyBank Trust, and in collaboration with the Utah Division of Aging and Adult Services, we developed a general protocol for assessing animal welfare issues in the in the lives of elder adults. We also developed a follow-up protocol that can be used in cases where elder adults have expressed concern about the welfare of their animals (including threatened and actual harm). Drafts of the protocols were reviewed by Utah Adult Protective Services personnel as well as experts in the field of gerontology. Final versions of the protocols were developed based …

Does Weather Or Site Characteristics Influence The Ability Of Scavengers To Locate Food?, Rebekah E. Ruzicka, Michael R. Conover

Wildland Resources Faculty Publications

Olfactory predators and scavengers rely on odors to locate food, and they forage primarily at night. We hypothesized that weather (e.g. wind speed, humidity, and temperature), vegetation, and landscape features affect the dissipation of odors in the atmosphere and, thus, impact the foraging efficiency of olfactory predators. We tested this hypothesis by assessing what conditions were correlated with the persistence of bait along the dike surrounding Willard Bay Reservoir, Utah. We distributed 124 chicken eggs and 199 dead European starlings (Sturnus vulgaris) as bait over 21 separate occasions spanning from May 21, 2009, to August 18, 2009. We used timers …

The Effects Of 24r, 25-Dihydroxyvitamin D3 And 24s, 25-Dihydroxyvitamin D3 On Phosphate Transport In Vivo, Yu Meng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research studied the effects of the two isomers of 24,25(OH)₂D₃ on phosphate absorption in vivo to increase our understanding of the effects of 24,25(OH)₂D₃ on phosphate transport in vivo, and its two isomers. The current work demonstrates that 24R,25(OH)₂D₃ is capable of decreasing phosphate absorption after a 1h injection in vivo and 24S,25(OH)₂D₃ can increase phosphate absorption after a 5h injection, but this stimulation disappears at time points after 5h.

Since 24,25(OH)₂D₃ is made in vitamin D-replete animals, the observation that 24R,25(OH)₂D …

Rotating Algal Biofilm Reactors: Mathematical Modeling And Lipid Production, Paul A. Woolsey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Harvesting of algal biomass presents a large barrier to the success of biofuels made from algae feedstock. Small cell sizes coupled with dilute concentrations of biomass in lagoon systems make separation an expensive and energy intense-process. The rotating algal biofilm reactor (RABR) has been developed at USU to provide a sustainable technology solution to this issue. Algae cells grown as a biofilm are concentrated in one location for ease of harvesting of high density biomass. A mathematical model of this biofilm system was developed based on data generated from three pilot scale reactors at the City of Logan, Utah wastewater …

Does Non-Steroidal Anti-Inflammatory Drug (Nsaid) Use Affect Dementia Progression And Survival Rates In Alzheimer's Disease? The Cache County Study, Trevor R. Buckley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alzheimer's disease (AD) has multiple factors that contribute to the disease process. Among these is a state of chronic inflammation that is endured by the brain during the aging process. The use of non-steroidal anti-inflammatory drugs (NSAIDs) decreases the amount of neuroinflammation sustained by the brain, and greater levels of NSAID use have been demonstrated to be associated with decreased probability of developing AD. This study looked at whether greater rates of NSAID use were also associated with decreased rates of cognitive and funtional decline and survival in a population-based sample of persons with AD. Linear mixed models failed to …

Outcomes Of Rotator Cuff Surgery In Utah Workers’ Compensation Patients, Jennifer R. Grewe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The rotator cuff is responsible for the lifting function of the shoulder and the circular movement of the arm. Rotator cuff injuries are the most common problem for the shoulder and account for approximately 4.1 million annual physicians visits. Approximately 20.7% of the population has at least one rotator cuff tear and more than 75,000 individuals will have rotator cuff surgery each year. Medical and compensation costs associated with a rotator cuff surgery are increasing and current estimated annual costs exceed 2 billion dollars. The increasing prevalence and cost associated with rotator cuff injuries in the United States population represents …

Effects Of Tannin-Containing Feed On Haemonchous Contortus In Sheep And Its Behavioral Implications, Jessica A. Juhnke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Herbivores prefer foods that supply required nutrients and avoid those with excess nutrients and plant secondary compounds (PSC). Nevertheless, PSC such as condensed tannins can provide beneficial medicinal effects to herbivores. The objectives of this study were to determine: 1) if parasitized lambs increased preference for a tannin-rich food after they experienced the beneficial antiparasitic effects of tannins relative to parasitized lambs that did not experience such benefits, 2) if preference for the tannin-containing food in the former group decreased when parasite burdens subsided, and 3) if the tannin-enriched food decreased parasitic burdens.

Twenty-two lambs were familiarized with beet pulp …

Molecular Interactions Of Salmonella With The Host Epithelium In Presence Of Commensals, Prerak T. Desai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Food-borne infections are a major source of mortality and morbidity. Salmonella causes the highest number of Food-borne bacterial infections in the US. This work contributes towards developing strategies to control Salmonella by (a) defining receptors used by Salmonella to adhere to and invade the host epithelium; (b) developing a host receptor based rapid detection method for the pathogen in food matrix; (C) and defining mechanisms of how probiotics can help alleviate Salmonella-induced cell death in the host epithelium.

We developed a cell-cell crosslinking method to discover host-microbe receptors, and discovered three new receptor-ligand interactions. Interaction of Salmonella Ef-Tu with …

Have Introduced Brown Trout (Salmo Trutta) Affected Native Aquatic Vertebrates In Western United States Streams?, Nora K. Burbank

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The introduction of exotic species to areas outside of their native range is one of the greatest threats to the biodiversity of native freshwater organisms. Exotic species have outcompeted native species for resources such as food and shelter, and in some cases these interactions have resulted in local extinctions or reductions in abundance of those native species. Brown trout are native to Eurasia, but have been introduced to much of the rest of the world, including the United States. In some parts of their introduced range, brown trout have substantially reduced the abundance and home ranges of some native fish …

Class-Wide Respect And Social Support Skill Training To Increase Peer Interactions Of Students With Autism Spectrum Disorders, Melanie Orton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The demand for effective social skills interventions for children with autism spectrum disorders is a pertinent issue for school-based professionals. One approach to increase appropriate social skills is to involve peer support by training a few socially competent children to positively interact with a student with an ASD. Potentially, training larger groups of children could result in increasing the number of different peers who would actively support positive interactions with their classmates with ASD. Thus, the present study investigated the effect of a class-wide peer-training strategy on the percentage of positive social interaction and number of peer contacts for three …

Fish Passage Through Rehabilitated Culverts Laboratory Study, Amber H. Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Slip lining culverts represent a low-cost technique that can restore life to decaying culverts. However, slip liners are smoother than typical host culverts; therefore, they generate higher flow velocities and lower flow depths within the culvert, which are fish passage barriers. One way to mitigate these barriers is by installing baffles. Unfortunately baffles can jeopardize the flow capacity of the culvert.

The Utah Water Research Laboratory (UWRL) at Utah State University contracted with the Utah Department of Transportation for $85,000 to test the effectiveness of baffles in improving fish passage through culverts. The goal of this project was to identify …

This is the first attempt to spatially assess wilderness conditions at the state level. A state-wide assessment of wilderness conditions allows local and regional managers to make informed regional decisions and to prioritize and direct their time and energy efficiently. This assessment clarifies the recreational use and impacts across the state. This study consists of two projects: 1) managers’ perceptions of the location and extent of resource and social condition problems; and 2) a geographic …

Using Species Distribution Models To Assess Invasion Theory And Provide Management Recommendations For Riparian Areas In The Eastern Columbia And Western Missouri River Basins, Diane R. Menuz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Globalization has created opportunities for plant and animal species to be transported to novel ecosystems. A subset of these species become invasive species, which are able to persist and spread rapidly to become influential components in their new ecosystems. Invasive species are often able to out-compete co-occurring native species and can alter fundamental ecosystem properties, such as soil nutrient availability or time between wildfires in a region. The United States is estimated to lose $34 billion per year to invasive plant species through costs to control unwanted species and lowered crop and forage production.

We used statistical models to better …
