The Impact Of Participation In The Food Dudes Healthy Eating Program On Dietary Habits In Fourth And Fifth Grade Students In Cache County Utah After One Year, Amanda B. Jones May 2014

The Impact Of Participation In The Food Dudes Healthy Eating Program On Dietary Habits In Fourth And Fifth Grade Students In Cache County Utah After One Year, Amanda B. Jones

All Graduate Theses and Dissertations

Adolescents are not consuming the recommended amounts of fruits and vegetables (FV). An overall decrease in diet quality is seen as adolescents get older, with decreases in fruit and vegetable intake and increases in energy dense food intake. The aim of this study was to test whether or not the Food Dudes (FD) healthy eating program helps to prevent decreases in fruit and vegetable intake and increases in energy dense foods during the transition from elementary school into middle school.

Past FD studies supported the use of repeated tasting, rewards, and role modeling to encourage children to eat more fruits ...


Influence Of Stand Composition On Soil Organic Carbon Stabilization And Biochemistry In Aspen And Conifer Forests Of Utah, Mercedes Roman Dobarco May 2014

Influence Of Stand Composition On Soil Organic Carbon Stabilization And Biochemistry In Aspen And Conifer Forests Of Utah, Mercedes Roman Dobarco

All Graduate Theses and Dissertations

Quacking aspen (Populus tremuloides Michx.) is an iconic species in western United States that offers multiple ecosystem services, including carbon sequestration. A shift in forest cover towards coniferous species due to natural succession, land management practices, or climate change may modify soil organic carbon (SOC) dynamics and CO2 emissions. The objectives of this study were to: (i) assess the effects of overstory composition on SOC storage and stability across the aspen-conifer ecotone, (ii) use Fourier transform infrared spectroscopy attenuated total reflectance (FTIR-ATR) to assess whether SOC storage is associated with preferential adsorption of certain organic molecules to the mineral surfaces ...


Factors Affecting The Toxic Cyanobacteria Nodularia Spumigena In Farmington Bay Of Great Salt Lake, Utah, B. Eric Mcculley May 2014

Factors Affecting The Toxic Cyanobacteria Nodularia Spumigena In Farmington Bay Of Great Salt Lake, Utah, B. Eric Mcculley

All Graduate Theses and Dissertations

Farmington Bay of Great Salt Lake receives a significant amount of the nutrient-polluted runoff from Salt Lake and Davis Counties, Utah. This nutrient-laden runoff has led to seasonal blooms of blue-green algae, Nodularia spumigena, which produce a toxin called nodularin that has been shown to be toxic to aquatic organisms, birds, and mammals. Nodularia spumigena are the most common algae found in Farmington Bay. This study focused on understanding the physical and chemical factors controlling the growth of Nodularia spumigena in order to improve our knowledge about how nutrients impact algae in the Great Salt Lake. The salinity of the ...


Ringtail Distribution, Dermatoglyphics, And Diet In Zion National Park, Utah, Adrian Argie Roadman May 2014

Ringtail Distribution, Dermatoglyphics, And Diet In Zion National Park, Utah, Adrian Argie Roadman

All Graduate Theses and Dissertations

Current scientific knowledge of the ringtail (Bassariscus astutus) is limited, thus impeding appropriate management decisions. Ringtails in Zion National Park, Utah, are rarely seen, but are involved in increasing occurrences of negative interactions with park visitors and employees such as food theft and denning in buildings, interactions which are harmful to both parties. To manage this conflict, an update to the general knowledge about the status of the population is required as the only previous study on ringtails in this area was conducted in the 1960s. Using noninvasive techniques provides dependable large-scale population information. I used two noninvasive detection methods ...


Nutrition And Genes Associated With Orofacial Cleft Birth Defects In Utah, Huong Dieu Meeks May 2014

Nutrition And Genes Associated With Orofacial Cleft Birth Defects In Utah, Huong Dieu Meeks

All Graduate Theses and Dissertations

Orofacial clefts (OFCs) are facial malformations that happen during early pregnancy and have a complex and heterogeneous etiology, involving both genetic and environmental risk factors. This project examined the association between maternal nutrition, folaterelated biomarkers, candidate genes involved in one-carbon metabolism (OCM), and OFCs in order to achieve more comprehensive knowledge of how nutrition and genetics influence OFC risk. First, the association between maternal periconceptional multivitamin (PCMV) use, maternal dietary patterns during the periconceptional period, and OFC risk was examined. This study showed that neither PCMV use nor healthy dietary pattern score alone was individually associated with OFC risk. However ...


Biochemistry Of Selenium In Pariette Wetlands, Utah, Colleen P. Jones May 2014

Biochemistry Of Selenium In Pariette Wetlands, Utah, Colleen P. Jones

All Graduate Theses and Dissertations

The Pariette Wetlands was constructed to provide wildlife habitat in an arid environment. Elevated levels of selenium (Se) have been detected in water, soil, and biota. Selenium concentrations have ranged from below detection limit to four times the water quality criterium limit. Here we report on three interrelated research topics: 1) selenium mass balance and flux in water, 2) selenium accumulation, concentration and volatilization of water and plant tissues; and 3) selenium sorption by upland and wetlands soils.

1) Mass balance and mass water flux of selenium for the Pariette Wetlands were studied. A comparison of inlet and outlet Se ...
