A Tree-Ring Based Reconstruction Of Logan River Streamflow In Northern Utah, Eric B. Allen, Tammy M. Rittenour, R. Justin Derose, Matthew F. Bekker, Roger Kjelgren, Brendan M. Buckley

Wasatch Dendroclimatology Research

[1] We created six new tree-ring chronologies in northern Utah, which were used with preexisting chronologies from Utah and western Wyoming to reconstruct mean annual flow for the Logan River, the largest tributary of the regionally important Bear River. Two reconstruction models were developed, a “Local” model that incorporated two Rocky Mountain juniper chronologies located within the basin, and a “Regional” model that also included limber pine and pinyon pine chronologies from a larger area. The Local model explained 48.2% of the variability in the instrumental record and the juniper chronologies better captured streamflow variability than Douglas-fir collected within the …

The Influence Of Snowmobile Trails On Coyote Movements During Winter In High-Elevation Landscapes, Eric M. Gese, Jennifer L. Burghardt Dowd, Lise M. Aubry

Wildland Resources Faculty Publications

Competition between sympatric carnivores has long been of interest to ecologists. Increased understanding of these interactions can be useful for conservation planning. Increased snowmobile traffic on public lands and in habitats used by Canada lynx (Lynx canadensis) remains controversial due to the concern of coyote (Canis latrans) use of snowmobile trails and potential competition with lynx. Determining the variables influencing coyote use of snowmobile trails has been a priority for managers attempting to conserve lynx and their critical habitat. During 2 winters in northwest Wyoming, we backtracked coyotes for 265 km to determine how varying snow characteristics influenced coyote movements; …

Mid-Latiude Rayleigh-Mie-Raman Lidar For Observations From 15 To 120 Km, Vincent B. Wickwar, Leda Sox, Joshua P. Herron, Matthew T. Emerick

Posters

Rayleigh lidar opened a portion of the atmosphere, from 30 to 90 km, to ground-based observations. Rayleigh-scatter observations were made at the Atmospheric Lidar Observatory (ALO) at Utah State University (USU) from 1993–2004 between 45 and 90 km. The lidar consisted of a 0.44-m diameter mirror, a frequency-doubled Nd:YAG laser opera'ng at 532-nm at 30- Hz at either 18- or 24-W, giving power- aperture products (PAPs) of 2.7- or 3.6- Wm2, respec'vely, and one detector channel. An example of what was accomplished with this system is shown as part of Fig. 1. The temperature climatology was based on ~5000 hours …

Pyrolysis Of Acrylonitrile-Butadiene-Styrene (Abs) Under High Heat Flux Conditions, James R. Wilson

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

Acrylonitrile-butadiene-styrene (ABS) is a common industrial plastic that is widely used for structural and piping applications. Additionally, within the past decade ABS has become the most popular material used in a type of rapid prototyping known as fused- deposition modeling (FDM). Within the past three years, ABS plastic blends have also been investigated as a potential fuel for hybrid- and solid-propelled rocket systems, exhibiting promising results. Because the use of ABS as a rocket propellant is very recent, a pyrolysis database, describing how ABS will burn, at the temperatures and heating rates experienced by rocket systems does not exist. Previous …

Temperatures In The Mid-Latitude Mesosphere During Sudden Stratospheric Warmings As Determined From Rayleigh Lidar Data, Leda Sox, Vincent B. Wickwar, Chad Fish, Joshua P. Herron

Graduate Student Posters

Sudden Stratospheric Warmings (SSWs) are major disturbances in the polar region of the winter hemisphere that cause major changes in stratospheric temperature and circulation. SSWs are characterized by a temperature increase of tens of degrees Kelvin, averaged over 60°-90° latitude, and a weakening of the polar vortex that persists for the order of a week at the 10 hPa level (roughly 32 km) [Labitzke and Naujokat, 2000]. The polar vortices are cyclones centered on both of the Earth’s poles that are present from the mid-troposphere to the lower stratosphere. Eastward zonal winds define the strong polar vortices in the winter. …

An Analysis On Soil Properties On Predicting Critical Hydraulic Gradients For Piping Progression In Sandy Soils, Tammy Jacobson

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

Piping is a form of internal erosion in which soil particles are eroded at a seepage exit location due to the forces imposed on the particles by seeping water. Laboratory testing was performed on a variety of soils in order to assess a correlation between unit weight, angle of internal friction, grain size, gradation, and void ratio and the critical hydraulic gradient at which piping initiates and progresses. A multi-variable regression analysis was used to form equations to predict critical hydraulic gradient based upon each of these soil parameters. Variations in the accuracy of these equations are thought to be …

Methylmercury Fate In The Hypersaline Environment Of The Great Salt Lake: A Critical Review Of Current Knowledge, Danielle Barandiaran

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

Methylmercury (MeHg) is a highly potent neurotoxic form of the environmental pollutant Mercury (Hg). The processes that are responsible for the conversion of Hg to MeHg are known to be both biotic and abiotic in freshwater systems. Although MeHg contamination is well documented in Great Salt Lake (GSL), the conversion of Hg into MeHg is not well-understood in saline environments much less in hypersaline waters such as GSL. The GSL is a broad, shallow high altitude (1280 m above sea level) lake that is exposed to large amounts of ultraviolet radiation and evaporation, which lead to great volatilization losses of …

Constraints On Patterns Of Abundance And Aggregation In Biological Systems, Kenneth J. Locey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the mechanisms that structure biological systems is a primary goal of biology. My research shows that the biological structure is constrained in important ways by general variables such as the number of base pairs in a genome and the number of individuals and species in a community. I used a combination of macroecology, bioinformatics, statistics, mathematics, and advanced computing to pursue my research and published several peer-reviewed scientific manuscripts and open-source software as a result.

I was funded through a combination of fellowships and scholarships awarded by the Utah State University School of Graduate Studies, College of Science, and …

Optimizing Systems For Cold-Climate Strawberry Production, Tiffany L. Maughan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Producing fruits and vegetables in the Intermountain West can be challenging due a short growing season, extreme temperatures, and limited availability of irrigation water. This is particularly true of strawberries, where commercial production is limited due to late fall and early spring frosts that shorten the growing season. With the increasing demand for local produce as urban populations grow and as consumer buying habits change, growers are looking for ways to overcome these climatic challenges. High tunnels are one option growers can use. High tunnels are similar to greenhouses, but less expensive to construct and to maintain. Another way to …

Evaluating The Smart Steps For Stepfamilies: Embrace The Journey Program, A Hierarchical Examination, Katie L. Reck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over the past decade, relationship education has grown as a means of enhancing couple relations. This study examines the experiences of 2,828 ethnically diverse and low-income adults who participated in the Smart Steps for Stepfamilies: Embrace the Journey program, a 12-hour stepfamily education program. Self-report measures of relationship quality, couple commitment, and relationship instability were gathered prior to and immediately after the Smart Steps intervention as well as six weeks, six months, and one year post-program. Results suggest that stepfamily participants experienced increases in relationship quality; however, these increases reduced to near pre-program levels one year after the programs completion. …
