Effects Of Feeding A Novel Alfalfa Leaf Pellet Product (Proleaf Max) And Alfalfa Stems (Profiber Plus) On Performance In The Feedlot And Carcass Quality Of Beef Steers, Laura A. Motsinger, Allen Young, Ryan Feuz, Ryan Larsen, Tevan J. Brady, Reganne K. Briggs, Brett R. Bowman, Chris Pratt, Kara J. Thornton

Animal, Dairy, and Veterinary Science Student Research

Alfalfa is often included in the diets of beef animals; however, the nutrient content of alfalfa is variable depending on the region in which it is grown, climate, soil, and many other factors. The leaf portion of alfalfa has a less variable nutrient composition than the stem portion of the plant. The variability that is present in the alfalfa plant can make the development of total mixed rations of consistent nutrient content difficult. As such, the purpose of this study was to determine how the inclusion of fractionated alfalfa leaves and alfalfa stems impacts performance and carcass quality of finishing …

Recreation Effects On Wildlife: A Review Of Potential Quantitative Thresholds, Jeremy S. Dertien, Courtney L. Larson, Sarah E. Reed

All Publications

Outdoor recreation is increasingly recognised for its deleterious effects on wildlife individuals and populations. However, planners and natural resource managers lack robust scientific recommendations for the design of recreation infrastructure and management of recreation activities. We reviewed 38 years of research on the effect of non-consumptive recreation on wildlife to attempt to identify effect thresholds or the point at which recreation begins to exhibit behavioural or physiological change to wildlife. We found that 53 of 330 articles identified a quantitative threshold. The majority of threshold articles focused on bird or mammal species and measured the distance to people or to …

Automation continues to play a greater role in agricultural production with commercial systems now available for machine vision identification of weeds and other pests, autonomous weed control, and robotic harvesters for fruits and vegetables. The growing availability of autonomous machines in agriculture indicates that there are opportunities to increase automation in cotton production. This article considers how current and future advances in automation has, could, or will impact cotton production practices. The results are organized to follow the cotton production process from land preparation to planting to within season management through harvesting and ginning. For each step, current and potential …

Movement At The Piano: Enhancing Engagement During Piano Lessons Through Movement And Storytelling, Erika Andrus

Music Student Research

Too often piano lessons consist of students sitting still at the piano. This leads to students either zoning out or getting wiggly and disruptive. This is a book of Dalcroze-inspired activities to help elementary age students internalize musical concepts, express themselves better musically, and be more engaged during piano lessons. In this resource, each unit will have a game, a listening activity, a story to act out, exercises to bring the concept to the piano, and a final piece to tie it all together.

Drought-Tolerant Options For Southwest Agriculture: Edible Produce, Emily Rice, Kynda R. Curtis

All Current Publications

The arid Southwest has been heavily impacted by drought and climate change. The Southwest states are some of the driest in the nation. From 2000 to 2020, 65% of the state of Utah experienced abnormally dry conditions, 78% of Arizona, 69% of New Mexico, and 71% of Nevada. Drought can damage pastures and crops, leading to economic losses in agriculture. Sustaining agricultural production (crops, food, livestock) on tribal lands will become progressively more challenging in the future due to decreased water availability, extended droughts, and changes in precipitation quantities and timing. This fact sheet is the second in a series …

Drought-Tolerant Options For Southwest Agriculture: Grasses, Grains, And Legumes, Emily Rice, Kynda R. Curtis

All Current Publications

The arid Southwest has been heavily impacted by drought and climate change. The Southwest states are some of the driest in the nation. Droughts damage pastures and crops, leading to economic losses in agriculture. This fact sheet is the first in a series of three that provide an overview of drought-tolerant crops, grasses, and native plants, which may assist in maintaining agricultural production for food and feed and sustain grasslands and rangelands in the arid Southwest. The following grasses, grains, and legumes used for forage, fodder, and human consumption, are all drought tolerant and, in many cases, tolerate salty soil …

Tuning Radiation And Microgravity Exposure For Human Brain Organoids, Bailey Mcfarland

Utah Space Grant Consortium

The environment of space, specifically radiation and microgravity, poses a substantial threat to astronauts' brain health. Understanding the damage mechanism and therefore paving the way to finding potential remedies is critical to protect astronauts during space flight. Current models are insufficient at representing the human brain, and insufficient research has been conducted on the effect of radiation and microgravity on the higher structures of the human brain. This ongoing research aims to use brain organoids, a tissue-engineered model that recapitulates the human brain's anatomy and structure and investigate the effects of radiation and microgravity on the brain. At the current …

Monitoring Acute Kidney Injury Risk With Urine Oxygen Partial Pressure, Lars Lofgren

Utah Space Grant Consortium

Acute kidney injury (AKI) is a common complication associated with cardiac surgery. AKI is associated with increased hospital costs, hospital length of stay (LOS), and mortality risk. The current diagnostic criteria rely on serum creatinine measurements and urine output data. Serum creatinine is not renal specific. It is known that there are factors other than renal injury that influence serum creatine concentrations. Serum creatinine levels are measured as concentrations which means large changes in fluid balance may alter the serum creatinine concentration. Urine output is not a reliable measurement of renal injury, either. During surgery it is common to administer …

Sickness Behaviors Across Vertebrate Taxa: Proximate And Ultimate Mechanisms, Patricia C. Lopes, Susannah S. French, Douglas C. Woodhams, Sandra A. Binning

Biology Faculty Publications

There is nothing like a pandemic to get the world thinking about how infectious diseases affect individual behavior. In this respect, sick animals can behave in ways that are dramatically different from healthy animals: altered social interactions and changes to patterns of eating and drinking are all hallmarks of sickness. As a result, behavioral changes associated with inflammatory responses (i.e. sickness behaviors) have important implications for disease spread by affecting contacts with others and with common resources, including water and/or sleeping sites. In this Review, we summarize the behavioral modifications, including changes to thermoregulatory behaviors, known to occur in vertebrates …

District-wide Aspen Habitat Restoration

Don DeLong

Ashley Egan

A habitat restoration project on the Greys River District is intended to tackle a host of wildlife issues, and our highest priority will be restoring a more natural balance of succession stages in aspen, big sagebrush, and mountain shrubland communities. Particular to aspen, the 2009 Greys River District Aspen Assessment doubled the known acreage of aspen and it identified 84% of the aspen acreage on the district as being overtopped by conifers by moderately-high to very-high degrees. Aspen stands in advanced stages of succession are given the highest priority for treatment. The …

Digital Scripture: An Investigation Of The Design And Use Of A Mobile Application For Reading Sacred Text, Neil Carpenter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Digital sacred text reading is rapidly growing as digital devices such as mobile smartphones are becoming more common across the globe. Although sacred text can have strong influence on identify and behavior, the effects of a digital revolution on scripture reading practices are not well understood. In particular, current research literature indicates that more information is needed about the design and use of digital sacred text applications (apps) such as mobile Bibles across different religious groups or cultures. Therefore, this study builds upon and extends previous work to analyze a religious text app, Gospel Library, which is designed and largely …

An Eulerian Perspective On Spring Migration In Mule Deer, Tatum Del Bosco

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many herbivores travel between low-elevation winter ranges and high-elevation summer sites. These seasonal movements allow them to avoid deep snow cover, ensure access to favorable habitat, and maximize food intake throughout the year. During the spring season, plants at lower elevations green up earlier at lower elevations than at higher elevations. It has been shown that individual animals will track this vegetation growth during their spring migration, which allows them to maximize forage intake coming out of the nutrient scarce winter. This phenomena has previously been studied by monitoring individual movement trajectories, but it is unknown how this pattern scales …

Snapdragon Cut Flower Production In Utah, Maegen Lewis, Melanie Stock, Tiffany Maughan, Brent Black, Dan Drost

All Current Publications

This fact sheet describes snapdragon cut flower production in Utah. Snapdragons can bloom spring through fall, with the highest quality stems produced during cool temperatures. Cultivars are grouped based on their blooming response to light and temperature. High-quality stem production can last up to 21 weeks by using multiple groups, staggered planting dates in a high tunnel and field, pinching, and pruning techniques.

Effects Of Sex And Autism On Oxytocin Receptors In The Substantia Nigra Of The Human Brain, Kip Dooley

Undergraduate Honors Capstone Projects

Oxytocin, a hormone present in the mammalian brain, has been shown to be a vital component of social function in animals and may have a role in the social deficits associated with Autism Spectrum Disorder in humans. Based on previous studies from our lab, there are oxytocin receptors in the human substantia nigra, a basal ganglia structure in the midbrain that is important in both movement and reward pathways. The substantia nigra contains two subsections that are defined by the neurotransmitters they contain: the pars compacta, which is dopaminergic, and the pars reticulata, which is GABAergic. By localizing oxytocin receptors …

Taphonomy Of Late Jurassic (Tithonian) Morrison Formation Apatosaurus Sp. Vertebrae Found Associated With Teeth From Allosaurus Sp. And Ceratosaurus Sp., And Body Size Extrapolation From The Associated Theropod Teeth., Greg C. Agyan

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

An Apatosaurus sp. locality from Dinosaur National Monument designated DNM-15 was excavated in 1985, and associated with two Allosaurus teeth and one Ceratosaurus tooth that were near one of the caudal vertebrae. The Ceratosaurus tooth was buried between an overlying rib and that same caudal vertebra. The caudal vertebrae of the DNM-15 Apatosaurus were intact and articulated, but the anterior skeleton was mostly absent, with a row of articulated sacral vertebrae in close association with a femur. Two other Allosaurus teeth were reported near the preserved ilium of the Apatosaurus, but they could not be located in the collections. …

Portrait Of Rich County, Adrian Thomson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Portrait of Rich County presents the small town of Randolph, Utah in poems describing its wildlife, recreational activities, and the perspectives of citizens in the contemporary rocky mountain west. Special attention to the imagination of the poems’ speaker toward the more dreamlike qualities of Rich County establishes itself throughout, in order to convey a feeling of hope within harsh terrain. This collection examines the theme of salvaging items not often considered, such as rusted junk, ancient houses, or roadside garbage, both in the actions of the speaker and through the act of naming these items upon the page. An over-arching …

Augmenting The Site Analysis Phase Of The Design Process Using Virtual Reality And Drones, Brandon Blauer

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Virtual reality (VR) is a tool that has been utilized by designers for decades now. In most cases, VR has been utilized in the latter part of the design process. More specifically, VR has been used most commonly towards the design review phase of the design process where people are often looking for a final design suggestion. With regards to the design review phase, there have been many reports discussing the effectiveness of VR. However, there has been little to no research regarding the use of VR in the site analysis phase of the design process.

The Sea Calls: A Selkie's Liminal Existence, Frances Avery

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Traditionally, the selkies (or seal people) of Scottish-Irish lore exist between spaces: the land and the sea, human and animal, childbearing and childless. Their existence at sea is voluntary but their existence on land is forced. Once the selkie has left behind its sealskin and both the literal and metaphorical sealskin has been stolen, the selkie becomes subject to human will. The lenses of body, reclamation, violation, and abuse prove that the reason why selkies have faded from popularity is because the lessons are too mature for a young audience. A feminist and queer reading and interpretation of this traditional …

Where Light Greets Night: A Modern Retelling Of "The Sea-Hare", Kelsie Peterson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Set in the Pacific Northwest, this contemporary retelling of the Brothers Grimm’s traditional tale sees a tower as a lighthouse, a princess as a keeper, and suitors as candidates for her replacement. The critical introduction of this thesis discusses the idea of “telephoning the narrative” and establishes the importance of modern fairy retellings. With an in-depth examination of binaries within the traditional tale and how they are handled within the retelling, the introduction sets the stage for the way “Where Light Greets Night” works to blur such black and white ideas. This tale also seeks to question judgment and bias …

A Review Of Harmful Algal Bloom Prediction Models For Lakes And Reservoirs, Jade Snyder Echard

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Anthropogenic activity has led to eutrophication in water bodies across the world. This eutrophication promotes blooms, cyanobacteria being among the most notorious bloom organisms. Cyanobacterial blooms (more commonly referred to as harmful algal blooms (HABs)) can devastate an ecosystem. Cyanobacteria are resilient microorganisms that have adapted to survive under a variety of conditions, often outcompeting other phytoplankton. Some species of cyanobacteria produce toxins that ward off predators. These toxins can negatively affect the health of the aquatic life, but also can impact animals and humans that drink or come in contact with these noxious waters. Although cyanotoxin’s effects on humans …

Personal Identity And The Influence Of Outlaw Folklore, William "Bacon" Nivison

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Folklore being a relatively new science there is still debate going on about what Folklore actually is. Most of what one reads is relative to who the “folk” are, where the “lore” comes from and how it is inspired. This thesis looks at folkore from a viewpoint which observes folklore from the other direction. Not how do the folk create the lore, rather how does the lore create the folk?

Folklore is well shown to be a product, or at least an abstract of one’s personal identity, but, is it not also a tool used by the individual in the …

Interactive Effects Of Soil And Browsing On Big Sagebrush: Implications For Restoration Success, Kyle Nehring

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Heterogeneity in landscape conditions (e.g., soil types) precludes a “one size fits all” management strategy across large landscapes. New management approaches that explicitly account for heterogeneous landscapes (and the variable conditions therein) will be required to maintain habitat quality. In particular, we require an improved mechanistic understanding of how the outcomes of conservation and restoration actions are contingent upon a) contextual abiotic factors (e.g., moisture availability mediated by soils and precipitation) and b) their interactions with biotic factors (e.g., browsing wildlife).

We propose to answer fundamental questions about how big sagebrush (Artemisia tridentata), the foundational species for sagebrush …

The River, The Residents, And The City: A Holistic Vision Study For Logan River's Upper Reach, Lisa Aedo

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The three-mile Upper Reach of the Logan River starting at the USU Water Lab to the 100 East bridge has been negatively impacted by residential development and diversion for agriculture and industry. A task force comprised of faculty at USU, professionals, government and city officials, and concerned residents has developed a Conservation Action Plan focused on twenty-two baseline indicators which, if improved, can help rehabilitate the river. This thesis looks at the factors that created the current challenges and seeks to provide a holistic vision with design solutions to address said challenges in alignment with that Plan. A literature review …

Power Of Near-Peers: Conceptualizing And Testing A Near-Peer Mentoring Model In Raising Youths' Self-Efficacy In Computer Programming, Chongning Sun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Self-efficacy is seen as a barrier for youth, females in particular, to enter computer science (CS). In this study, I presented a near-peer mentoring model that focused on changing the mentee’s self-efficacy in CS. The present study had three objectives: (a) to design a near-peer mentoring model (i.e., a conceptual model) around the sources of information that influence self-efficacy, (b) to develop a mentor training model based on the conceptual model, and (c) to test the effectiveness of the training model in increasing mentees’ self-efficacy in the context of a summer App programming camp. The present study adopted a mixed-methods …

Mechanisms Of Overyielding And Coexistence In Diverse Tallgrass Prairie Communities, Leslie E. Forero

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plants compete for the same basic nutrient and water resources. According to the competitive exclusion principle, when a substantial overlap in resource pools exists, the best competitor for resources should drive all other species to extinction. The ability for plants to coexist in violation of the competitive exclusion principle is the “biodiversity paradox”. Coexistence is actually beneficial for plants: as species diversity increases, you typically see increases in plant biomass production (known as the biodiversity-productivity relationship). The mechanisms behind coexistence and the biodiversity-productivity relationship remain an ecological mystery. One hypothesis is that plants obtain water and nutrients from different places …

The Effects Of Trace Mineral Supplementation On Performance, Health, And Carcass Quality Of At-Risk Mineral Deficient Feedlot Cattle, Tevan J. Brady

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Morbidity in feedlot cattle due to disease is a common economical loss for feedlot producers. Utah is not typically considered a ‘feedlot state’, but there are several producers in the southern part of the state that specialize in receiving at-risk cattle. These cattle are at-risk because they are coming from areas known to be mineral deficient. Areas such as the western US, are known to be deficient in several trace minerals important in immune response. Therefore, it is critical that producers have an adequate plan to decrease the negative effects that this has on economic viability of their beef operations, …

Range-Wide Migratory Connectivity Of Painted Buntings, Andrew J. Sharp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Painted Bunting (Passerina cirus) is a small (~16g), short/medium-distance migratory songbird that is listed as a species of conservation concern by the US Fish and Wildlife Service. Painted Buntings breed in two distinct populations, one eastern population and one interior population, separated by a 500 km gap that stretches from Mississippi to Georgia. I analyzed tracking data from 112 Painted Buntings from 11 different breeding sites to explore how individuals from different breeding sites differ in wintering location (chapter 2) and migratory timing (chapter 3). Additionally, I examined differences in migratory behavior between male and females in …
