Biology Faculty Publications

Destruxins (DTXs) are cyclic depsipeptides produced by many Metarhizium isolates that have long been assumed to contribute to virulence of these entomopathogenic fungi. We evaluated the virulence of 20 Metarhizium isolates against insect larvae and measured the concentration of DTXs A, B, and E produced by these same isolates in submerged (shaken) cultures. Eight of the isolates (ARSEF 324, 724, 760, 1448, 1882, 1883, 3479, and 3918) did not produce DTXs A, B, or E during the five days of submerged culture. DTXs were first detected in culture medium at 2–3 days in submerged culture. Galleria mellonella and Tenebrio molitor …

A Shortcut For Multiple Testing On The Directed Acyclic Graph Of Gene Ontology, Garrett Saunders, John R. Stevens, S. Clay Isom

Mathematics and Statistics Faculty Publications

Background: Gene set testing has become an important analysis technique in high throughput microarray and next generation sequencing studies for uncovering patterns of differential expression of various biological processes. Often, the large number of gene sets that are tested simultaneously require some sort of multiplicity correction to account for the multiplicity effect. This work provides a substantial computational improvement to an existing familywise error rate controlling multiplicity approach (the Focus Level method) for gene set testing in high throughput microarray and next generation sequencing studies using Gene Ontology graphs, which we call the Short Focus Level.

Results: The Short Focus …

Justice And Immigrant Latino Recreation Geography In Cache Valley, Utah, Jodie Madsen, Claudia Radel, Joanna Endter-Wada

Environment and Society Faculty Publications

Latinos are the largest U.S. non-mainstreamed ethnic group, and social and environmental justice considerations dictate recreation professionals and researchers meet their recreation needs. This study reconceptualizes this diverse group’s recreation patterns, looking at where immigrant Latino individuals in Cache Valley, Utah do recreate rather than where they do not. Through qualitative interviews and interactive mapping, thirty participants discussed what recreation means to them and explained their recreation site choices. Findings suggest that recreation as an activity done outside the home, for fun with others, leads participants to seek spaces with certain characteristics. Reconceiving recreation more broadly and framing it from …

Grain Finishing Beef: Alternative Rations, Cattle Performance And Feeding Costs For Small Feeders, Dillon M. Feuz, Jesse Russell

All Current Publications

In a feeding trial at Utah State University during the summer of 2013, it was found that cattle had higher ADG when fed SFC compared to whole corn. However, when the relative cost of SFC and whole corn were considered, feeding whole corn compared to SFC resulted in nearly identical feed costs per pound of gain. Actual and relative costs of SFC and whole corn can and do vary over time and across geographic regions. Therefore, feeders could use the information in this fact sheet to determine which feed will be the most economical for them.

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; …

STEM fields in the US continue to be dominated by people whose cultural backgrounds are White, English-speaking, and middle class (National Academy of Engineering and National Research Council, 2009). Many reasons have been offered to explain this phenomenon: Students’ backgrounds may include worldviews, beliefs, and communicative practices that do not cohere with those practiced in STEM classrooms (Aikenhead & Jegede, 1999; Lee, 1999); instructional materials may present STEM fields as a-cultural, decontextualized practices with no evident connection to students’ lives and communities, such as the routine completion of numerical exercises (O’Halloran, 2005); students’ identities—shaped in part by their desired life …

The decline of greater sage-grouse distribution and population densities across western North America has led conservation, research, and management objectives to focus efforts on understanding sage-grouse populations across their range. The purpose of this study was to gain a better understanding of direct and indirect predation effects on hen survival and nest success of sage-grouse. The project was conducted in Hot Springs and Park Counties in the Bighorn Basin of Wyoming. The study had three main objectives: 1) obtain and quantify the types and impacts of predators on sage-grouse hen survival and nest success, 2) compare the effect predator removals …

Determination Of The Expression Patterns Of Bovine Non-Classical Major Histocompatibility Complex (Mhc) Class I Proteins, Parveen Parasar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This project was funded by the United States of Department of Agriculture (USDA), which funds research aimed at improving production and animal health. The aim of this study was to advance knowledge of maternal immune tolerance to the fetus and mechanisms bovine non-classical MHC class I proteins employ to interact with immune cells and render them inert towards the fetus.

A fetus is a tissue graft inside the mother’s uterus yet must be accepted by the mother to maintain a successful pregnancy. Reproductive insufficiency and pregnancy failure are major causes of production loss in cattle, especially in cloned animals. Knowledge …

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 …

Characterization Of The Hydrogen Peroxide Stress Responses Of Bifidobacterium Longum And Bifidobacterium Animalis Subsp. Lactis, Taylor S. Oberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Probiotics are living organisms which exert a beneficial health effect when consumed in sufficient numbers. Consumer interest in probiotics has increased dramatically in recent years prompting an increase in production and development of functional foods. One major problem is the decreased viability of probiotic bacteria during functional food production and storage and subsequent digestion due to environmental stresses. The most common probiotic strains belong to the genus Lactobacillus or Bifidobacterium. Due to the anaerobic nature of these bacteria, they lack the required defense mechanisms for oxidative stress inherent in aerobic microorganisms. This study examined the oxidative stress responses of …

Winter Waterbird Ecology On The Great Salt Lake, Utah, And Interactions With Commercial Harvest Of Brine Shrimp Cysts, Anthony J. Roberts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Interactions among commercial fisheries and birds have been studied in open ocean ecosystems and at aquaculture facilities. On the Great Salt Lake (GSL), Utah, USA, a commercial harvest of brine shrimp (Artemia franciscana) eggs (i.e. cysts) occurs annually during fall and winter. Coinciding with commercial harvest is the use of the GSL by millions of waterbirds which has the potential to result in conflict among industry and birds. The objectives of my research were to examine fall and winter ecology of birds using the GSL and interactions with the brine shrimp cyst harvest. I examined the influence of temperature and …

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 …

Benchmarking An Optimal Pattern Of Pollution Trading: The Case Of Cub River, Utah, Arthur Caplan, Yuya Sasaki

Applied Economics Faculty Publications

This paper employs a recently developed, dynamic trading algorithm to establish a benchmark pattern of trade for a potential water quality trading (WQT) market in the Cub River sub-basin of Utah; a market that would ultimately include both point and nonpoint sources. The algorithm accounts for three complications that naturally arise in trading scenarios: (1) combinatorial matching of traders, (2) trader heterogeneity, and (3) discreteness in abatement technology. The algorithm establishes as detailed a reduced-cost benchmark as possible for the sub-basin by distinguishing a specific pattern of trade among would-be market participants. As such, the algorithm provides a benchmark against …
