Greater Sage-Grouse Habitat Selection And Use Patterns In Response To Vegetation Management Practices In Northwestern Utah, Stephanie E. Graham May 2013

Greater Sage-Grouse Habitat Selection And Use Patterns In Response To Vegetation Management Practices In Northwestern Utah, Stephanie E. Graham

All Graduate Theses and Dissertations

Greater sage-grouse (Centrocercus urophasianus; sage-grouse) currently occupy an estimated 56% of the potential range-wide pre-European settlement habitat. Population declines have been largely attributed to direct habitat loss and fragmentation related to anthropogenic activities that promote wildfires and the subsequent spread of invasive plants. Vegetation manipulations, including the seeding of plant species, such as forage kochia (Bassia prostrata), have been identified as potential strategies to mitigate the risk of wildfire and enhance sage-grouse habitat in areas at risk to wildfires. I evaluated the composition changes that occurred in a lower elevation sagebrush (Artemisia spp.) plant community within the Grouse Creek Watershed ...


Kisspeptins - Expression, Purification, And Biological Assays, Mathew Puthayathu Kurian May 2013

Kisspeptins - Expression, Purification, And Biological Assays, Mathew Puthayathu Kurian

All Graduate Theses and Dissertations

Kisspeptins are an arginine-phenylalanine-amide family of neuroactive peptide hormones encoded by the KISS1 gene, which, along with its receptor GPR54, are essential for the initiation of puberty in adolescents and maintenance of reproductive function in adults. Kisspeptins are also involved in the sexual dimorphism of the brain. Kisspeptin signaling defects are implicated in reproductive disorders like idiopathic hypogonadotropic hypogonadism, precocious puberty and polycystic ovarian syndrome. Kisspeptins were originally discovered as metastasis suppressors in melanoma cell lines and have also been found to down regulate metastasis in breast and ovarian cancers. They have been found to inhibit the colonization of secondary ...


Characterization Of The Product Specificity And Kinetic Mechanism Of Protein Arginine Methyltransferase 1, Shanying Gui May 2013

Characterization Of The Product Specificity And Kinetic Mechanism Of Protein Arginine Methyltransferase 1, Shanying Gui

All Graduate Theses and Dissertations

Protein arginine methylation is an essential post-translational modification catalyzed by protein arginine methyltransferases (PRMTs). Type I PRMTs transfer the methyl group from S-adenosyl-L-methionine (AdoMet) to the arginine residues and catalyze the formation of monomethylarginine (MMA) and asymmetric dimethylarginine (ADMA). Type II PRMTs generate MMA and symmetric dimethylarginine (SDMA). PRMT-catalyzed methylation is involved in many biological processes and human diseases when dysregulated. As the predominant PRMT, PRMT1 catalyzes an estimated 85% of all protein arginine methylation in vivo. Nevertheless, the product specificity of PRMT1 remains poorly understood. A few articles have been published regarding the kinetic mechanism of PRMT1, yet with ...


Ecology Of Coyotes On The Valles Caldera National Preserve, New Mexico: Implications For Elk Calf Recruitment, Suzanne J. Gifford May 2013

Ecology Of Coyotes On The Valles Caldera National Preserve, New Mexico: Implications For Elk Calf Recruitment, Suzanne J. Gifford

All Graduate Theses and Dissertations

Valles Caldera National Preserve (VCNP) managers were concerned about low elk recruitment observed at the same time as an apparent increase in sightings of coyotes and observations of coyote predation on elk calves. The goal of this study was to describe coyotes’ ecological interactions with elk, particularly coyote diet and movements on the Valle Grande, a large grassland meadow in the southeastern portion of the VCNP.

We examined coyote diet by quantifying undigested remains of food items in coyote scats (feces). The most frequent taxa were rodents (montane voles and pocket gophers), elk (adult and calf), insects (grasshoppers and beetles ...


Study Of Genes Relating To Degradation Of Aromatic Compounds And Carbon Metabolism In Mycobacterium Sp. Strain Kms, Chun Zhang May 2013

Study Of Genes Relating To Degradation Of Aromatic Compounds And Carbon Metabolism In Mycobacterium Sp. Strain Kms, Chun Zhang

All Graduate Theses and Dissertations

Polycyclic aromatic hydrocarbons, produced by anthropological and natural activities, are hazardous through formation of oxidative radicals and DNA adducts. Growth of Mycobacterium sp. strain KMS, isolated from a contaminated soil, on the model hydrocarbon pyrene induced specific proteins. My work extends the study of isolate KMS to the gene level to understand the pathways and regulation of pyrene utilization. Genes encoding pyrene-induced proteins were clustered on a 72 kb section on the KMS chromosome but some also were duplicated on plasmids. Skewed GC content and presence of integrase and transposase genes suggested horizontal transfer of pyrene-degrading gene islands that also ...


A Multi-Scale Investigation Of Factors Limiting Bull Trout Viability, Tracy Bowerman May 2013

A Multi-Scale Investigation Of Factors Limiting Bull Trout Viability, Tracy Bowerman

All Graduate Theses and Dissertations

Effective conservation strategies for imperiled species require an understanding of processes that influence fitness throughout the organism's life cycle and across the range of habitats needed to complete that cycle. I evaluated factors that affect population viability of bull trout Salvelinus confluentus, a threatened freshwater char species, throughout individual life stages and over the entire life cycle. I assessed the relationship between bull trout egg incubation success and environmental variables. Egg survival was negatively related to the percent of fine sediment in redds and positively related to hydraulic conductivity and the strength of downwelling. Next, I quantified juvenile bull ...


Cougar Predation Behavior In North-Central Utah, Dustin L. Mitchell May 2013

Cougar Predation Behavior In North-Central Utah, Dustin L. Mitchell

All Graduate Theses and Dissertations

Cougar (Puma concolor) predation has been identified as being one of several factors contributing to the decline of mule deer (Odocoileus hemionus) throughout the Western United States. In order to better understand how these elusive felines utilize their surroundings and prey, I examined and analyzed cougar predation behavior in North-Central Utah, using global positioning systems (GPS) data from 2002-2010. Twenty-three cougars were fitted with GPS collars and monitored for prey caching behavior. In total 775 potential cache sites were visited and 546 prey remains found. Mule deer comprised the majority of prey at cougar cache sites, but 11 other species ...


Characterization Of Lactose Monolaurate For Its Antimicrobial And Emulsification Properties And Its Effect On Crystallization Behavior Of Anhydrous Milk Fat, Ashwini Wagh May 2013

Characterization Of Lactose Monolaurate For Its Antimicrobial And Emulsification Properties And Its Effect On Crystallization Behavior Of Anhydrous Milk Fat, Ashwini Wagh

All Graduate Theses and Dissertations

There is a constant need of new synthetic emulsifiers in the food industry. Sugar esters are widely used as food grade synthetic emulsifiers, amongst which sucrose esters are the most common. Although sucrose esters are used very frequently, little is known about the use of lactose esters in food. There is a need for characterization of lactose esters before they can be used in foods. The objective of this study was to characterize a lactose ester, lactose monolaurate (LML) as an antimicrobial agent on food pathogens, evaluate its effect on 20 % oil-in-water emulsions as an emulsifier, and to explore its ...

All Graduate Theses and Dissertations

The continued increase in the demand for fossil fuels combined with their ever dwindling supply has prompted the search for a suitable alternative fuel. The research contained within this dissertation seeks to increase the lipid content of cellular feedstocks, improve extraction efficiencies of lipids, and understand the pathways involved in the production of fatty alcohols and triacylglycerides from microbial feedstocks. As part of this research the diatom, Cheatoceros gracilis, was grown at small and large scale to determine optimal growing conditions. No apparent nutrient stress trigger was required to initiate the accumulation of the biodiesel precursor triacylglyceride, unlike other documented ...


Evidence Of Agrarian Urbanism: Land Use Preferences Of Residents Living On Small Acreage Farms Or Large Lots With Animal Rights In Cache Valley, Utah, Laurie B. Hurst May 2013

Evidence Of Agrarian Urbanism: Land Use Preferences Of Residents Living On Small Acreage Farms Or Large Lots With Animal Rights In Cache Valley, Utah, Laurie B. Hurst

All Graduate Theses and Dissertations

Until the last half century, land development patterns in the Intermountain West were designed after the Mormon settlement pattern. With its gridiron streets and in-town farmsteads, this pattern gave families the opportunity to grow crops and raise a few animals on their one acre or less in town with the added advantage of having a social life. Over the last century, small farms have dwindled and large farms have increased in size. However, in the Intermountain West the farmstead tradition continues with families who grow gardens and raise animals on their large city lots, who value self-sufficiency, and who thrive ...


Modeling Usa Stream Temperatures For Stream Biodiversity And Climate Change Assessments, Ryan A. Hill May 2013

Modeling Usa Stream Temperatures For Stream Biodiversity And Climate Change Assessments, Ryan A. Hill

All Graduate Theses and Dissertations

Stream temperature (ST) is a primary determinant of individual stream species distributions and community composition. Moreover, thermal modifications associated with urbanization, agriculture, reservoirs, and climate change can significantly alter stream ecosystem structure and function. Despite its importance, we lack ST measurements for the vast majority of USA streams. To effectively manage these important systems, we need to understand how STs vary geographically, what the natural (reference) thermal condition of altered streams was, and how STs will respond to climate change. Empirical ST models, if calibrated with physically meaningful predictors, could provide this information. My dissertation objectives were to: (1) develop ...


An Environmental History Of The Bear River Range, 1860-1910, Bradley Paul Hansen May 2013

An Environmental History Of The Bear River Range, 1860-1910, Bradley Paul Hansen

All Graduate Theses and Dissertations

The study of environmental history suggests that nature and culture change all the time, but that the rate and scale of such change can vary enormously. During the late 19th and early 20th centuries, Anglo settlement in the American West transformed landscapes and ecologies, creating new and complex environmental problems. This transformation was particularly impressive in Cache Valley, Utah's Bear River Range. From 1860 to 1910, Mormon settlers overused or misused the Bear River Range's lumber, grazing forage, wild game, and water resources and introduced invasive plant and animal species throughout the area. By the turn of the ...


Evaluating Eriogonum Corymbosum Tolerance To Frequent Irrigation And Evaluating Its Significant Morphological Variations For Potential Cultivars, Graham C. Hunter May 2013

Evaluating Eriogonum Corymbosum Tolerance To Frequent Irrigation And Evaluating Its Significant Morphological Variations For Potential Cultivars, Graham C. Hunter

All Graduate Theses and Dissertations

Two separate experiments were designed to assess the value of Lacy Buckwheat (Eriogonum corymbosum ) as a low water landscape plant. Low water use landscapes can contribute to water conservation in arid climates. Developing a palette of plants that are both attractive and drought tolerant can promote the acceptance of low water use landscapes as an alternative to the traditional bluegrass landscapes of the Intermountain West. Eriogonum corymbosum is an attractive subshrub species native to low rainfall areas of the Colorado Plateau. A strip plot design containing four repetitions with four randomly assigned plants each of Eriogonum corymbosum , Eriogonum thompsoniaeand the ...


Apoptotic And Epigenetic Induction Of Embryo Failure Following Somatic Cell Nuclear Transfer, Aaron Patrick Davis May 2013

Apoptotic And Epigenetic Induction Of Embryo Failure Following Somatic Cell Nuclear Transfer, Aaron Patrick Davis

All Graduate Theses and Dissertations

Somatic cell nuclear transfer (SCNT) is a useful tool for selective breeding, conservation, and production of transgenic animals. Despite the successful cloning of several species, high rates of embryo failure following SCNT prevent the wide-scale use of the technique. Embryos produced through cloning have a higher incidence of developmental arrest, decreased developmental potential, frequent implantation failures, and increased incidence of abortion. The objective of this dissertation research was to characterize the factors that lead to SCNT failures by examining epigenetic and apoptotic pathways that can negatively influence the development of cloned preimplantation embryos. Aberrant genome reprogramming is generally considered to ...

The effects of mastering 1F (flat position-fillet) welds on carbon steel using a sequenced pattern of welding was examined. Participants (N = 71) were randomly assigned a specific sequence of welding between Gas Metal Arc Welding (GMAW) and Shielded Metal Arc Welding (SMAW). The hypothesis of teaching beginning welders the GMAW process before the SMAW process to improve the ability to master American Welding Society (AWS) welds was tested. A welding pretest was administered to determine any prior welding knowledge. Sixty minutes of welding instruction taught proper welding safety, machine set-up, arc length, travel speed, work angle, and correct bead formation ...


The Micronutrient Profile Of The Typical American Diet Enhances Colorectal Carcinogenesis, Stephany Del Carmen Perez Monsanto May 2013

The Micronutrient Profile Of The Typical American Diet Enhances Colorectal Carcinogenesis, Stephany Del Carmen Perez Monsanto

All Graduate Theses and Dissertations

The typical Western dietary pattern is characterized by the consumption of energy-dense, nutrient-poor foods and has been linked to increased risk of colorectal cancer (CRC). Our research group previously developed the total Western diet (TWD) that emulates typical human dietary intakes of macro- (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals) on an energy density basis for rodents. In the present study, we sought to determine the impact of TWD on biomarkers of metabolic syndrome and obesity in comparison to a commercial 45% fat diet used for models of diet-induced obesity (DIO diet) and the standard basal AIN93G diet ...


Effects Of Integrating Mathematical Concepts Into An Animal Science Curriculum, Andrea Rae Clark May 2013

Effects Of Integrating Mathematical Concepts Into An Animal Science Curriculum, Andrea Rae Clark

All Graduate Theses and Dissertations

Nationwide, mathematical scores have been a topic of concern among elementary and secondary educators for many years. Decreasing math skills are also trickling into post-secondary education, requiring universities to provide additional remedial math instruction in colleges and universities. Studies have been conducted to discover the most effective pedagogical methods of teaching math. Teaching contextualized math has been found to be effective and includes providing a direct application to real-life scenarios rather than teaching linear equations and algebraic principles outside of their application. A study was conducted measuring the effects of integrating mathematical skills in an animal science curriculum. Eight Utah ...


Studies On Nitrogen And Silicon Deficiency In Microalgal Lipid Production, Curtis Adams May 2013

Studies On Nitrogen And Silicon Deficiency In Microalgal Lipid Production, Curtis Adams

All Graduate Theses and Dissertations

Microalgae are a rich, largely untapped source of lipids. Algae are underutilized, in part, because lipid formation generally is stimulated by stress, such as nutrient deficiency. Nutrient deficiencies reduce growth, resulting in a tradeoff between elevated cellular lipids and abundant cell division. This tradeoff is not well understood. We also have a poor understanding of the physiological drivers for this lipid formation. Here we report on three sets of research: 1) Assessment of species differences in growth and lipid content tradeoffs with high and low level nitrogen deficiency; 2) Investigation of physiological drivers of lipid formation, by mass balance accounting ...


Self-Limitation As An Explanation For Species' Relative Abundances And The Long-Term Persistence Of Rare Species, Glenda Marie Yenni May 2013

Self-Limitation As An Explanation For Species' Relative Abundances And The Long-Term Persistence Of Rare Species, Glenda Marie Yenni

All Graduate Theses and Dissertations

Much of ecological theory describes species interactions. These interactions often play an important theoretical role in facilitating coexistence. In particular, rarity in ecological communities, though often observed, provides a significant challenge to theoretical and empirical ecologists alike. I use a plant community model to simulate the effect of stronger negative frequency dependence on the long-term persistence of the rare species in a simulated community. This strong self-limitation produces long persistence times for the rare competitor, which otherwise succumb quickly to stochastic extinction. The results suggest that the mechanism causing species to be rare in this case is the same mechanism ...


Effects Of Inorganic Nutrients And Dissolved Organic Carbon On Oxygen Demand In Select Rivers In Northern Utah, Joseph L. Crawford May 2013

Effects Of Inorganic Nutrients And Dissolved Organic Carbon On Oxygen Demand In Select Rivers In Northern Utah, Joseph L. Crawford

All Graduate Theses and Dissertations

Sewage, agricultural runoff, and atmospheric deposition have greatly increased the amount of nutrients (largely nitrogen (N) and phosphorus (P)) in surface water nationwide. Excess nutrients are associated with algal blooms and dissolved oxygen depletion in many water bodies, but linkages between nutrients and dissolved oxygen have been largely correlative. Biochemical oxygen demand (BOD) is a regulated water quality parameter that is aimed at describing the amount of oxygen consumed during the decomposition of organic matter. Despite the awareness that excess nutrients are linked to dissolved oxygen in rivers, few studies in the nutrient criteria literature discuss BOD measurements or how ...

Food Environments: What Is The Role Of Demographics In Figians' Decision Making Related To Food Choice And Overall Nutrition Behavior, Sandra Bradshaw

All Graduate Theses and Dissertations

Due to the recent increased quantity of nutrition-related diseases worldwide, current research recommends exploring environmental factors that influence this trend. The Islands of Fiji are of particular concern because of the growing number of non- communicable diseases. On the same small island, nutrition problems vary according to demographic. Thus, the different environments of each demographic constitute diverse food environments, which are manifested in varied nutrition concerns. This study explored environmental motivators of food choice for the Fijian population. Gathering the perspectives of Fijian Islanders using a narrative inquiry research format proved to be insightful in measuring the environmental influences of ...

All Graduate Theses and Dissertations

Oxidation in oils and muscle foods has been studied for many years to understand its mechanism and furthermore to control and manage it. A series of different processing steps or different packaging techniques can alter oxidative stability. The objective of the current study was to examine oxidative stability of processed oil and to evaluate the effect of carbon dioxide generating mineral on quality of beef and chicken under different storage conditions. In Study 1 (Chapter 3), the effect of ultrasound on oxidative stability of interesterified soybean oil and soybean oil was examined. Sonication did not affect oxidation rate until the ...


Interspecific Interactions Between Penstemon Palmeri And Shrubs In The Arid Shrublands Of The Spring Mountains, Nevada, Jesse M. Poulos May 2013

Interspecific Interactions Between Penstemon Palmeri And Shrubs In The Arid Shrublands Of The Spring Mountains, Nevada, Jesse M. Poulos

All Graduate Theses and Dissertations

A project involving shrub removal was undertaken by the United States Forest Service in the Spring Mountains National Recreation Area (SMNRA) to reduce accumulated woody fuels, which can pose risks to human communities. This research focuses on the interactions between shrubs and the perennial forb Palmer's penstemon (Penstemon palmeri), one of many nectar sources for the endemic Spring Mountains Acastus Checkerspot Butterfly (Chlosyne acastus ssp robusta). Initial observations revealed that P. palmeri (`penstemon') seemed to grow almost exclusively under shrubs. Such spatial associations are often indicative of a history of positive interactions between plants, and led to the research ...


Colorado River Cutthroat Habitat Resistance And Resilience To Climate Change, Kate Olsen May 2013

Colorado River Cutthroat Habitat Resistance And Resilience To Climate Change, Kate Olsen

All Graduate Theses and Dissertations

Colorado River cutthroat trout, Oncorhyncus clarki pleuriticus , occupy less than 12% of their historic range. Restoration and conservation of this species are currently under way across the upper Colorado River basin, but guidance to inform management decisions related to the impacts of climate change on cutthroat is lacking. Shifts in the thermal distribution of freshwater fish have been documented, and will continue to occur as cold water habitat is threatened by warming water temperatures. Coupled air and water temperature data allow for an estimation of potential resistance and resilience to warming, determining the effect that local air has on stream ...


Strategic Approaches To Develop Optimal Feeding Program Of Brown Midrib Corn Silage To Lactating Dairy Cows In The Intermountain West, Michael Shane Holt May 2013

Strategic Approaches To Develop Optimal Feeding Program Of Brown Midrib Corn Silage To Lactating Dairy Cows In The Intermountain West, Michael Shane Holt

All Graduate Theses and Dissertations

In two lactation studies reported in this dissertation, it was hypothesized that feeding 35% brown midrib corn silage (BMRCS) and 25% alfalfa hay (dry matter basis) would result in increased dry matter intake (DMI) around peak lactation compared with feeding conventional corn silage (CCS), causing longer peak milk production, and that feeding dairy cows in early lactation a 16% crude protein diet with fair quality alfalfa hay (FAH) in BMR-based diets would maintain milk production, reduce urinary N excretion, and improve N efficiency compared to those fed high quality alfalfa hay (HAH) in CCS- or BMR-based diets. A third experiment ...


Investigation Of The Oxidation/Reduction Of Prmt1, Substrate Interactions With Prmt1, And The Role Of Argining Methylation In Rna Surveillance, Damon V. Nitzel May 2013

Investigation Of The Oxidation/Reduction Of Prmt1, Substrate Interactions With Prmt1, And The Role Of Argining Methylation In Rna Surveillance, Damon V. Nitzel

All Graduate Theses and Dissertations

Protein arginine methylation is an abundant post-translational modification catalyzed by protein arginine methyltransferases (PRMTs). Arginine methylation plays important roles in a variety of cellular pathways and human diseases. PRMT1, the predominant PRMT, catalyzes approximately 85% of all protein arginine methylation in vivo. While many details of how PRMT1 functions have been uncovered through the past two decades, there are many details which remain unclear, including how arginine methylation is regulated, how PRMT1 binds substrates, and what role PRMTs play in RNA surveillance. Our recent data presented in this thesis showed that reduction of the PRMT1 enzyme, following recombinant expression and ...


Assessing Vehicle-Related Mortality Of Mule Deer In Utah, Daniel D. Olson May 2013

Assessing Vehicle-Related Mortality Of Mule Deer In Utah, Daniel D. Olson

All Graduate Theses and Dissertations

Roads are essential in modern societies, but as populations grow and traffic volumes rise, roads will continue to be built and expanded. As a result, the effects that roads have on wildlife will likely intensify, making it imperative that managers understand those effects so mitigation can be directed accordingly. In Utah, considerable areas of mule deer (Odocoileus hemionus) habitat have been bisected by roads. Mule deer are commonly involved in vehicle collisions and there is concern that roads and vehicle traffic are impacting populations. This project was conducted to determine the number and demographic effects of deer-vehicle collisions, to examine ...


Evaluation Of Survey Methods And Development Of Species Distribution Models For Kit Foxes In The Great Basin Desert, Stephen J. Dempsey May 2013

Evaluation Of Survey Methods And Development Of Species Distribution Models For Kit Foxes In The Great Basin Desert, Stephen J. Dempsey

All Graduate Theses and Dissertations

Historically, kit foxes (Vulpes macrotis) once occupied the desert and semi-arid regions of southwestern North America, ranging from Idaho to central Mexico. Their range-wide decline has warranted the kit fox to be listed as endangered in Colorado, threatened in California and Oregon, and designated as a state sensitive species in Idaho and Utah. Once considered the most abundant carnivore in western Utah, the kit fox has been in steep decline over the past decade, creating a demand to determine kit fox presence. Currently there is little consensus on which survey methodology is best to detect kit fox presence. We tested ...


Causes And Consequences Of Local Variability In Aroga Websteri Clarke Abundance Over Space And Time, Virginia L.J. Bolshakova May 2013

Causes And Consequences Of Local Variability In Aroga Websteri Clarke Abundance Over Space And Time, Virginia L.J. Bolshakova

All Graduate Theses and Dissertations

With increasing pressures on sagebrush steppe ecosystems, the sagebrush defoliating Aroga moth, Aroga websteri Clarke (Lepidoptera: Gelechiidae) has become a critical organism of concern. Despite the cyclic nature of A. websteri outbreaks throughout the Great Basin, there is limited information on the moth’s population dynamics. The goal of this dissertation was to develop effective means of assessing and describing population trends of the Aroga moth across space and time, and potentially promoting biological control of the moth to prevent unnaturally large, prolonged and destructive outbreaks. Field studies were conducted to: 1) monitor and quantify activity of the Aroga moth ...


Vital Rates, Population Trends, And Habitat-Use Patterns Of A Translocated Greater Sage-Grouse Population: Implications For Future Translocations, Orrin V. Duvuvuei May 2013

Vital Rates, Population Trends, And Habitat-Use Patterns Of A Translocated Greater Sage-Grouse Population: Implications For Future Translocations, Orrin V. Duvuvuei

All Graduate Theses and Dissertations

Translocations have been used as a management strategy to successfully augment declining native wildlife populations. Greater sage-grouse (Centrocercus urophasianus; sage-grouse) population declines on Anthro Mountain, Utah prompted managers to translocate sage-grouse and test protocols from a successful translocation project in Strawberry Valley, Utah. Sage-grouse from Parker Mountain, Utah were used as the source population for Anthro Mountain and Strawberry Valley translocations. Sixty hens were translocated to Anthro Mountain in 2009 and 2010; I monitored vital rates of the 60 translocated hens and 32 resident hens from 2009-2012. My objective was to determine the overall success of the translocation 4 years ...
