Irrigation Water Loss And Recovery In Utah, Bradley S. Crookston, Troy Peters, Matt Yost, Burdette Barker

All Current Publications

When deciding which irrigation systems to adopt, permit, or promote, it is important to consider how their efficiency and losses affect the water balance of Utah’s watersheds and drainage basins. Irrigators have no control over precipitation and only limited control of surface waters entering and leaving the state, as most of those are controlled by legal agreements. However, Utah’s water managers, elected officials, and water users can consider how surface water flows and groundwater storage is affected by using more efficient irrigation systems. Sprinkler, surface, or drip irrigation systems each have trade-offs in irrigation application efficiency, cost, and other factors. …

Transcriptomic Analysis Of Xeroderma Pigmentosum Group C Skin Samples, Austen N. Gleave

Theses and Dissertations

Xeroderma Pigmentosum is a rare genetic disorder caused by defective DNA damage repair enzymes. This condition results in an increased risk of developing skin cancer and other symptoms in those affected. In this thesis, we examined the effects of Xeroderma Pigmentosum on gene expression in patient skin biopsy samples. To accomplish this, we utilized statistical analysis of spatial transcriptomic and single-cell RNA sequencing techniques to discover differences between patient and heterozygous carrier skin samples. We found that the skin samples from Xeroderma Pigmentosum patients showed elevated levels of inflammation, immune activation, and cellular stress, while the carrier skin samples leaned …

On-Farm Research Guide, Matt Yost, Jody Gale, Earl Creech, Megan Baker, Jeffrey Austin, Grant Cardon, Cody Zesiger

All Current Publications

Many growers want to increase crop productivity and farm profitability. On-farm research is a way growers can achieve this goal by discovering answers to important questions about the benefits of using specific products or practices they are uncertain about or are unproven. Validating the efficacy of already-implemented practices is another important reason to do on-farm research trials (Nielsen, 2008). Each farm is unique and can benefit from individualized on-farm research, especially since university and industry researchers cannot study every product or practice for every unique field or farm growing condition. This how-to guide covers benefits and best practices for conducting …

Guide To Drought Tolerance Of Utah Field Crops, Matt Yost, Tina Sullivan, Dakota Boren, Luree Johnson, Melanie Mills, Earl Creech, Boyd Kitchen, Randall Violett

All Current Publications

Crop variety selection is one of the most important choices on the farm. Crop genetics determine a significant portion of the yield potential and resource use efficiency. Crop types and genetics that use water more efficiently will become increasingly important as water becomes scarcer. Throughout Utah and the Western United States, water availability is decreasing due to various factors, including reduced snowpack and rapid urban growth. Alfalfa, other hay, small grains, and corn are grown on more acres than any other crops in Utah and much of the Intermountain West. These crops all have varieties, hybrids, and cultivars with the …

Psychosocial Mediators Of A Physical Activity And Dietary Intervention In Pregnant Women With Overweight Or Obesity, Meghan Baruth, Sarah Wilcox, Jihong Liu, Rebecca Schlaff

Faculty Publications

Background

Mediation analyses provide insight into both ‘pieces’ of the mediation chain; they allow us to look into the ‘black box’ that is behavior change. They allow researchers to better understand the ‘how’ of an intervention’s effects and/or the ‘why’ behind why an intervention worked or did not work. The lack of publications in pregnant populations highlights the need for additional studies to be conducted and published. The purpose of this study is to examine the psychosocial mediators of physical activity and dietary outcomes in a sample of pregnant women with overweight or obesity participating in the Health in Pregnancy …

Comparing The Effect Of Hyposalinity On The Clearance Rate Of The Invasive Mussel Mytilus Galloprovincialis From Marina Del Rey And The Native Mussel Mytilus Trossulus From Coos Bay, Or, Lainee Irribarren, M. Christina Vasquez

Honors Thesis

Salinity is a key environmental factor that influences the physiology and distribution of intertidal mussels. Climate change is predicted to increase freshwater runoff and intensify hyposaline stress in coastal habitats. Previous research has established the mussel Mytilus trossulus as more hyposaline tolerant compared to its competitive congener M. galloprovincialis, however the physiological responses underlying this tolerance have not been studied. Thus, this study examined how reduced salinity affects clearance rate, a measure of feeding performance, in the invasive mussel M. galloprovincialis from Marina del Rey, CA and the native mussel M. trossulus from Coos Bay, OR. I hypothesized that clearance …

New Species Of Kronosvirus Bacteriophages That Infect Caulobacter Strain Cbr1, Tannaz Mohammadi, Austin Millwood, Maherah Shaik, Bert Ely

Faculty Publications

Caulobacter segnis strain CBR1 enhances the germination rate and total biomass of Arabidopsis plants. Since bacteriophages are usually present in the rhizosphere, we isolated three additional bacteriophages, designated TMCBR2, TMCBR3, and W2, that can replicate using CBR1 as the host strain. The genome sizes and morphologies of the new phages were similar to those of the previously isolated Kronos phage, and when we compared the nucleotide sequence of these new phage genomes, we found only minor differences among the four phage genomes. Pairwise sequence comparisons indicated that the phage genomes should be grouped into three separate species within Kronosvirus genus. …

Soil Nutrient Sufficiency Does Not Ensure Plant Nutrient Status, Chandralekha Joga Miss

Scholars Week

Soil testing is commonly used to guide nutrient management. However, plants may not use nutrients in the same way that soil tests predict. This can happen when nutrients interact and limit uptake. This study evaluated whether soil test results match plant nutrient status under different compost levels, with a focus on nutrient antagonism. Soils from three compost histories were used: no compost (T1), moderate compost (T2), and long-term high compost from repeated hog manure application (T3). Soils were mixed with ProMix and Perlite (1:1:1), and Chijimisai was grown under greenhouse conditions. Plant height and chlorophyll (SPAD) were measured weekly. Soil …
