Joseph Franckum and Professor Kent Hatch, Integrative Biology Examining the ratios of stable isotopes (non-decaying atoms with extra neutrons) in animal tissues can yield important information about an organism, such as detecting diet change or establishing migratory origin. Information gathered from these studies help develop future practices to care for certain species. A better understanding of […]

Growth Rates, Diet, and Distribution of Pictetiella expansa, a Rare Rocky Mountain Perlodidae Stonefly (Plecoptera)
Sarah Walker and Dr. C. Riley Nelson, Biology The stonefly Pictetiella expansa has been acknowledged as a species since the 1920s, yet little is known about this rare species of Perlodidae stonefly. The purpose of our study was to document the growth rates and feeding behaviors of Pictetiella expansa in the American Fork River as […]
Examining Links between the LDS Faith and Cervical Cancer Mortality Rates of the American West
Austin Parker and Dr. Ruth Kerry, Geography Several medical geography studies have identified Utah as an outlier in terms of various illnesses with far lower rates than other states in the country. Gooaverts (2009) noticed small clusters of low cervical cancer rates in Utah compared to other states, although he wasn’t specifically studying the heavy […]
Whose Legs are in the Water? Parsing out Community Composition and Turnover Rates of Plecoptera, Trichoptera, and Ephemeroptera
Sarah Walker and Dr. C. Riley Nelson, Department of Biology Many beta diversity indicies, like most analytical tools in ecology, abstract the known relative abundances and species presence into outputs primarily useful for obtaining p-values and little else. Therefore, the purposes of this proposed beta diversity method were to simplify currently used similarity analyses for […]
Estimating Dispersal of Spring Invertebrates through Genetic Diversity
Keith Tanner and Dr. Dennis Shiozawa, Department of Biology The Great Basin contains many closed basins, separated by north-south lying mountain ranges and low east-west lying divides. The Sierra Nevada, on the western edge of the Great Basin, generates a rain shadow, making Nevada the driest state in the nation, with Utah as the second […]
Modifying the Apical Ectodermal Ridge in Embryological Development of Vertebrates
Lauren Clough and Dr. Jeffery R. Barrow, Physiology and Developmental Biology Introduction Vertebrate embryonic limb development is a complex process that involves many genes and processes. Patterning takes place along three axes, including the proximal-distal axis of the limb. The Apical Ectodermal Ridge (AER) helps to guide development along the proximal-distal axis, but the genetic […]
Likely Voters, Low Response Rates, and Little Coverage Error: Advances in Internet Preelection Polling Methodology
Ashley Burton and Dr. Quin Monson, Political Science The purpose of my research was to determine if internet preelection surveys administered to a probability proportionate to size (PPS) sample are able to reduce coverage error by including likely voters, even if the response rates are low. This research was conducted during the Utah 3rd District […]
Graduation Rates of Latino Students: Contributing and Deterring Factors
Rebecca Richards and Dr. Betty Ashbaker, CPSE A major concern among educators is the consistently high number of dropouts among Latino students. While the graduation rate has improved over the last decade, this improvement has been marginal. According to a study done in 2001, 43.4% of Hispanic students ages 16-24, born out of the country, […]
In Vivo Specific Degradation of Selected RNA Substrates by Endogenous tRNA 3’ Processing Endoribonuclease
Duane R. Wesemann The enzyme tRNA 3’ Processing Endoribonuclease (3’tRNase) is suspected to be an enzyme responsible for 3’ end processing of various pre-tRNAs. Our lab has demonstrated that RNAs containing a hairpin structure can be manipulated to appear as a “pre-tRNA” molecule and be recognized and cleaved by 3’tRNase. This is accomplished by the […]
ANALYSIS OF THE STRENGTH AND INFLUENCE OF DEMOGRAPHIC FACTORS IN DETERMINING CONVERT BAPTISM RATES IN LDS MISSIONS
Darin G. Clay and Dr. Mark Showalter, Economics It is a well-known fact that the success of the missionary effort of the Church is highly correlated with economic prosperity. Specifically, the convert baptism rates are higher in less prosperous nations than in relatively wealthy nations. Opponents of the Church have cited this fact in support […]
