Consequences Of Cattle Introduction In A Shrubsteppe Ecosystem: Indirect Effects On Desert Horned Lizards (Phrynosoma Platyrhinos), T.A. Scott Newbold, James A. Macmahon Sep 2008

Consequences Of Cattle Introduction In A Shrubsteppe Ecosystem: Indirect Effects On Desert Horned Lizards (Phrynosoma Platyrhinos), T.A. Scott Newbold, James A. Macmahon

Western North American Naturalist

Livestock grazing is one of the most common forms of land use in the western United States, yet scientists struggle to accurately predict grazing impacts. This study examined the initial response of desert horned lizards (Phrynosoma platyrhinos) to cattle introduction at a site in northwestern Utah. We sampled 21 grazed and 7 ungrazed study plots before grazing (2001), after grazing (2002), and 1 year after the cessation of grazing (2003). We were specifically interested in whether grazing influenced lizards through biotic or abiotic pathways. Lizard response (based on scat counts) to the initial impact of grazing (<6 months after cattle introduction) suggests that lizards abandoned areas protected from grazing (i.e., ungrazed exclosures) presumably in favor of grazed areas. Avoidance of ungrazed plots by lizards coincided with a decline in shrub and grass cover on grazed plots and with no significant change in relative abundance or richness of prey (ants) on grazed plots. In 2003, one year after cattle had been removed from the site, prey species richness declined on ungrazed plots, and percent bare ground increased on previously grazed plots; however, we detected no response of lizards to these changes. Overall, these results add to a growing consensus that responses by small vertebrates to grazing are largely the result of changes to habitat structure (i.e., vegetation cover), rather than to changes in prey availability. Importantly, results from our relatively unique evaluation of initial …

Polygynous Mating Behavior In The Endangered Tehuantepec Jackrabbit (Lepus Flavigularis), Tamara Rioja, Consuelo Lorenzo, Eduardo Naranjo, Laura Scott, Arturo Carrillo-Reyes Sep 2008

Polygynous Mating Behavior In The Endangered Tehuantepec Jackrabbit (Lepus Flavigularis), Tamara Rioja, Consuelo Lorenzo, Eduardo Naranjo, Laura Scott, Arturo Carrillo-Reyes

Western North American Naturalist

This is the 1st effort to determine the mating behavior of the Tehuantepec jackrabbit (Lepus flavigularis), an endangered endemic species from southern Mexico whose distribution is limited to the Isthmus of Tehuantepec region. Between June 2006 and December 2007, observations of 60 adult radio-marked jackrabbits were carried out in Santa María del Mar, Oaxaca, Mexico. Direct observations showed that the breeding season of the Tehuantepec jackrabbit lasted an average of 200 days per year, with a high-intensity period during the rainy season (May–October); we also confirmed a polygamous reproductive behavior for this species. More importantly, we showed that …

Influence Of Pocket Gopher Mounds On Nonnative Plant Establishment In A Shrubsteppe Ecosystem, G. Page Kyle, Andrew Kulmatiski, Karen H. Beard Sep 2008

Influence Of Pocket Gopher Mounds On Nonnative Plant Establishment In A Shrubsteppe Ecosystem, G. Page Kyle, Andrew Kulmatiski, Karen H. Beard

Western North American Naturalist

Soil disturbances across a wide range of spatial scales have been found to promote the establishment of invasive plant species. This study addresses whether mounds built by northern pocket gophers (Thomomys talpoides) in the shrubsteppe environment of north central Washington are facilitating plant invasions into native-dominated fields. Research was conducted in native-dominated plant communities adjacent to ex-arable, nonnative-dominated fields. To determine the effect of mounds on plant growth, we recorded new establishment and persistence of all plant species over 2 growing seasons on 10–19 mound and intermound areas in 10 fields. Nonnative plant establishment was not affected by …

The Claustrum In Autism And Typically Developing Male Children: A Quantitative Mri Study, Warren B. Davis Sep 2008

The Claustrum In Autism And Typically Developing Male Children: A Quantitative Mri Study, Warren B. Davis

Theses and Dissertations

The claustrum (Cl) is a subcortical gray-matter structure housed between the external capsule medially and the extreme capsule laterally. Due to its extensive reciprocal connections throughout the brain, it has been implicated in consciousness and other higher order functions including linking behavior and emotion. Such linkage may be important in understanding the neurobiology of autism since other cortical and subcortical regions including the spatially and ontologically related basal ganglia, as well as limbic structures, have been implicated in the disorder. Participants were males with autism (n=16) and typically developing (TD; n=14) matched for head circumference and age. The Cl and …

Making Sense Of Their World: Sensory Awareness And Sensory Reactivity As Predictors Of Social Interaction In Early Childhood, Cortney Anne Evans Sep 2008

Making Sense Of Their World: Sensory Awareness And Sensory Reactivity As Predictors Of Social Interaction In Early Childhood, Cortney Anne Evans

Theses and Dissertations

The purposes of this study were to (a) test the validity of a sensory reactivity measure adapted for parents of preschool-age children, (b) examine if different modalities of sensory reactivity (i.e. smell, touch, taste, etc.) emerge together or if differing thresholds of reactivity exist between sensory modalities, (c) see how parental ratings of preschoolers' sensory reactivity are related to children's behaviors in the classroom, and (d) see if sensory reactivity bears different relationships to children's social behaviors than do other aspects of temperament. A total of 260 parents (242 mothers, 18 fathers) and 10 teachers of 260 children (131 male, …

Of Soils And Souls: The Parable Of The Sower, Jared M. Halverson Sep 2008

Of Soils And Souls: The Parable Of The Sower, Jared M. Halverson

Religious Educator: Perspectives on the Restored Gospel

There are certain stories which are not so much the heritage of the scholar and the material of the theologian as the possession of every man; and such are the parables of Jesus. Even in an age when men know less and less of the Bible, and care less for it, it remains true that the stories Jesus told are the best known stories in the world.

Rationality And Reproduction: Health Insurance Coverage And Married Women's Fertility, Jennifer Adams Mendoza Aug 2008

Rationality And Reproduction: Health Insurance Coverage And Married Women's Fertility, Jennifer Adams Mendoza

Theses and Dissertations

Health insurance has become essential in mediating the extremely high costs of childbirth; however, it has been neglected in fertility research. This study examines health insurance coverage as an economic determinant of fertility and includes discussions of the cost of raising children, contraception and childbirth as well as opportunity costs to illustrate that the effect of health insurance may differ by resources, such as income and education. Using data from the 2001 Survey of Income and Program Participation, I analyze the effects of insurance on the probability of pregnancy and birth with Discrete-Time Hazard Models. Results show that health insurance …

Memoirs Of The Persecuted: Persecution, Memory, And The West As A Mormon Refuge, David W. Grua Aug 2008

Memoirs Of The Persecuted: Persecution, Memory, And The West As A Mormon Refuge, David W. Grua

Theses and Dissertations

The memory of past violence in Missouri and Illinois during the 1830s and 1840s shaped how members of the Church of Jesus Christ of Latter-day Saints (Latter-day Saints or Mormons) saw themselves, their persecutors, and the states and the nation where the violence occurred. This thesis explores the role of collective memory of violence in forming Mormon identities and images of place from 1838, when governor Lilburn W. Boggs expelled the Latter-day Saints from Missouri, to 1858, with the conclusion of the Utah War. I argue that Latter-day Saint authors during these two decades used the memory of persecution to …

Determining The Role Of Wnt5a Signaling In Embryonic Limb Outgrowth Via Clonal Analysis, Whitney Herrod Sowby Aug 2008

Determining The Role Of Wnt5a Signaling In Embryonic Limb Outgrowth Via Clonal Analysis, Whitney Herrod Sowby

Theses and Dissertations

The exact mechanisms that regulate limb outgrowth the mouse embryo are unknown. Although there are several models, we favor a hypothesis where cells become polarized by signals secreted from the AER which orient their cell migration and/or divisions causing limb outgrowth. Clonal analysis has provided a mechanism to study cell behavior. We have generated a targeting construct containing the Fgf8 inhibitor, Sprouty2, in order to generate mutant clones for behavioral analyses in the limb. In order to more effectively study clonal behavior we report the modification of a novel clonal analysis approach, exo-utero surgery. We have modified, enhanced and proven …

I. Thermodynamics And Magnetism Of Cu2ocl2 Ii. Repairs To Microcalorimeter The "2"S Are Subscripts, And The Second 2 Is Preceded By A Lower Case L, Not A One, Thomas J. Parry

Theses and Dissertations

Adiabatic calorimetry provides accurate and precise specific heat (Cp) data. From this data, thermodynamic functions may be calculated. Cu2OCl2, melanothallite, became of interest as part of a study of a particular thermochemical cycle. The experimental specific heat data and the calculated thermodynamic functions are reported here. Free energies of formation, calculated from the thermodynamic functions, suggest the particular cycle of interest with this compound as an intermediate is not feasible; uncertainty as to the accuracy of CuO and CuCl2 data used in the calculations indicate further study may be necessary. Upon collection of the specific heat data, an antiferromagnetic transition …

The Antioxidant Defense Network: Synergistic Combinations To Prevent Oxidative Damage, Amy Marie Clement Aug 2008

The Antioxidant Defense Network: Synergistic Combinations To Prevent Oxidative Damage, Amy Marie Clement

Theses and Dissertations

One of the matchless ironies of the human body is its requirement for the highly reactive oxygen molecule, which has been clearly implicated in many diseases and the aging processes. Oxidants produced by metabolic processes damage cells by starting chemical chain reactions including oxidation of DNA and proteins as well as lipid peroxidation. Damage to DNA can cause mutations and lead to cancer if not reversed by DNA repair mechanisms. Damage to proteins causes enzyme inhibition, denaturation and protein degradation. Lipid peroxidation can cause cell lysis as well as creating mutagenic and carcinogenic by-products. The human body contains antioxidants and …

Domain Duplication, Darwinian Selection, And The Origin Of The Globulin Seed Storage Proteins, Nathaniel S. Cannon Aug 2008

Domain Duplication, Darwinian Selection, And The Origin Of The Globulin Seed Storage Proteins, Nathaniel S. Cannon

Theses and Dissertations

The seed storage globulins found among virtually all spermatophytes comprise a multi-gene family of proteins with ancient evolutionary origins. The two main groups of storage globulins include the legumins (11S) and vicilins (7S), both of which play a main role in protein deposition and storage in the seed endosperm. Composed of two cupin domains (bicupin), these proteins have been recently noted not only for their close structural relationships among the two subfamilies (7S and 11S) but also for their similarity to other proteins such as germin-like proteins (GLP's), bacterial oxalate decarboxylases, and other cupin containing proteins. Previous studies have investigated …

Self-Esteem, Self-Efficacy And Gender In Social Class Reproduction, Spencer L. James Aug 2008

Self-Esteem, Self-Efficacy And Gender In Social Class Reproduction, Spencer L. James

Theses and Dissertations

The observation that middle class parents tend to have middle class children is rather obvious. Why this is so has been the subject of less research than the fact that it is so. Using the National Survey of Families and Households (NSFH), I employ theories about social class reproduction to examine and evaluate a model that scrutinizes the influence of self-efficacy and self-esteem on college completion or current enrollment and investigate gender differences. I find that self-esteem and self-efficacy play a vital role in social class outcomes. However, I find no evidence of gender differences in the social class reproduction …

A Radical Conjugate Addition Approach To The Total Synthesis Of Celogentin C, Steven G. Capps Aug 2008

A Radical Conjugate Addition Approach To The Total Synthesis Of Celogentin C, Steven G. Capps

Theses and Dissertations

The synthesis of five chiral DBFOX (dibenzofuran-oxazoline) ligands with either aryl or benzyl substituents will be presented. The requisite amino alcohols were obtained with high enantioselectivity either commercially (DBFOX/Bn), via Sharpless asymmetric aminohydroxylation (DBFOX/Nap, DBFOX/t-BuPh, DBFOX/Pip), or via phase-transfer catalyzed asymmetric alkylation (DBFOX/MeNap). These ligands, complexed with Mg(NTf2)2, were used as Lewis acid promoters of enantioselective radical conjugate additions to α/β-unsaturated nitro-amides/esters. A summary of these results is presented and discussed. These findings led us to believe that our initial binding model between metal, ligand, and substrate was flawed. Thus, we figured that if we started with a functionality known …

Parowan Valley Gaming Pieces And Insights Into Fremont Social Organization, Molly Allison Hall Aug 2008

Parowan Valley Gaming Pieces And Insights Into Fremont Social Organization, Molly Allison Hall

Theses and Dissertations

This thesis primarily addresses the implications of Fremont gaming pieces in the Parowan Valley. First, I review ethnographic gaming pieces and compare them to the Fremont worked bone pieces in order to support the idea that they were used by the Fremont in games similar to the ones recorded ethnographically. Then, I analyze a collection of Fremont gaming pieces from excavations at three Parowan Valley sites. I note drastic differences in the characteristics found on pieces inside the Parowan Valley and those form outside the Parowan Valley. It is also clear that gaming pieces are being produced in the Parowan …

Fmri Evidence Of Group Differences On The Word Memory Test In A Sample Of Traumatic Brain Injury Patients, James Douglas Larsen Aug 2008

Fmri Evidence Of Group Differences On The Word Memory Test In A Sample Of Traumatic Brain Injury Patients, James Douglas Larsen

Theses and Dissertations

The Word Memory Test (WMT) is a popular effort test that requires participants to memorize lists of paired words and repeat them back in a variety of different memory tasks. Four brain injured patients participated in two trials of the delayed recall (DR) portion of the WMT while undergoing fMRI scanning. In the first trial subjects put forth full effort, and during the second trial subjects were instructed to simulate increased memory impairment in order to represent poor effort. fMRI activation from both trials were compared in order to contrast full and simulated poor effort activation patterns during the WMT. …

Patterns Of Social Participation: Assessing The Long-Term Effects Of Creating Social Capital, Camille Miller Aug 2008

Patterns Of Social Participation: Assessing The Long-Term Effects Of Creating Social Capital, Camille Miller

Theses and Dissertations

Given the numerous benefits noted in academic research from having social capital, investigators may now turn to looking at what makes a person likely to create it. In this study I examine whether building social capital in high school through participation in religious, athletic, and volunteer activities makes individuals more likely to continue to create it as adults through participation in similar activities. Using data from the National Education Longitudinal Study, I employ both multilevel and seemingly unrelated regression models. I find that early participation in religious and athletic activities increases the likelihood of doing two out of three social …

Three-Dimensional Direct Numerical Simulation Of Soot Formation And Transport In A Temporally Evolving Nonpremixed Ethylene Jet Flame, David O. Lignell, Jacqueline H. Chen, Philip J. Smith Jul 2008

Three-Dimensional Direct Numerical Simulation Of Soot Formation And Transport In A Temporally Evolving Nonpremixed Ethylene Jet Flame, David O. Lignell, Jacqueline H. Chen, Philip J. Smith

Faculty Publications

Three-dimensional direct numerical simulation of soot formation with complex chemistry is presented. The simulation consists of a temporally evolving, planar, nonpremixed ethylene jet flame with a validated, 19-species reduced mechanism. A four-step, three-moment, semiempirical soot model is employed. Previous two-dimensional decaying turbulence simulations have shown the importance of multidimensional flame dynamical effects on soot concentration [D.O. Lignell, J.H. Chen, P.J. Smith, T. Lu, C.K. Law, Combust. Flame 151 (1–2) (2007) 2–28]. It was shown that flame curvature strongly impacts the diffusive motion of the flame relative to soot (which is essentially convected with the flow), resulting in soot being differentially …

The Effects Of Manageable Corrective Feedback On Esl Writing Accuracy, K James Hartshorn Jul 2008

The Effects Of Manageable Corrective Feedback On Esl Writing Accuracy, K James Hartshorn

Theses and Dissertations

The purpose of this study was to test the effect of one approach to writing pedagogy on second-language (L2) writing accuracy. This study used two groups of L2 writers who were learning English as a second language: a control group (n = 19) who were taught with traditional process writing methods and a treatment group (n = 28) who were taught with an innovative approach to L2 writing pedagogy. The methodology for the treatment group was designed to improve L2 writing accuracy by raising the linguistic awareness of the learners through error correction. Central to the instructional methodology were four …

Changes In Kindergarteners' Writing Complexity When Using Story Elements, Lynne M. Watanabe Jul 2008

Changes In Kindergarteners' Writing Complexity When Using Story Elements, Lynne M. Watanabe

Theses and Dissertations

This study examined changes in kindergarteners' writing complexity after implementing writing instruction based on story elements (character, setting, problem, and solution). Writing samples from six students of three ability levels (i.e., beginning, intermediate, and advanced) were collected over a six-week period within a guided writing context. These samples included three types of texts (oral language, pictures, and written text)and were analyzed using two analytic rubrics specifically created for this study, one for writing development and the other for the inclusion of story elements. Findings from this study suggest that all students, regardless of ability level wrote in more complex ways …

The Compatibility Of Containment And Autonomy In Lydia Minatoya's The Strangeness Of Beauty, Rachel Jeppsen Jul 2008

The Compatibility Of Containment And Autonomy In Lydia Minatoya's The Strangeness Of Beauty, Rachel Jeppsen

Theses and Dissertations

Subaltern studies has overwhelmingly privileged subaltern resistance as a means for the subaltern to attain autonomy. While the group's project has made breakthroughs in rewriting Indian subaltern history, their emphasis on resistance to oppression has also essentialized what it means to create autonomy. A 1999 novel, Lydia Minatoya's The Strangeness of Beauty, challenges this essentialist view by portraying alternative behaviors that indicate autonomy. The novel is set in 1920s Japan when transnational excitement and anxiety provided opportunities for one subaltern group, Japanese women, to gain autonomy. While some feminist movements in Japan substantiate the notion that autonomy must be gained …
