Early Brood-Rearing Habitat Use And Productivity Of Greater Sage-Grouse In Wyoming, Kristin M. Thompson, Matthew J. Holloran, Steven J. Slater, Jarren L. Kuipers, Stanley H. Anderson Aug 2006

Early Brood-Rearing Habitat Use And Productivity Of Greater Sage-Grouse In Wyoming, Kristin M. Thompson, Matthew J. Holloran, Steven J. Slater, Jarren L. Kuipers, Stanley H. Anderson

Western North American Naturalist

Populations of Greater Sage-Grouse (Centrocercus urophasianus) have been declining throughout their range since the 1960s. Productivity, which includes production and survival of young, is often cited as a factor in these declines. We monitored radio-equipped Greater Sage-Grouse at 3 sites in western Wyoming to assess early brood-rearing habitat use (through 14 days post-hatch) and productivity. Logistic and linear regression analyses with Akaike's Information Criterion were used to evaluate early brooding habitat use and to examine relationships between productivity and vegetation, insect size and abundance, and weather parameters. Females with broods were found in areas with greater sagebrush canopy …

Influence Of Fire And Juniper Encroachment On Birds In High-Elevation Sagebrush Steppe, Anna C. Noson, Richard A. Schmitz, Richard F. Miller Aug 2006

Influence Of Fire And Juniper Encroachment On Birds In High-Elevation Sagebrush Steppe, Anna C. Noson, Richard A. Schmitz, Richard F. Miller

Western North American Naturalist

We examined relationships between high-elevation sagebrush (Artemisia spp.) steppe habitats altered by prescribed fire and western juniper (Juniperus occidentalis) encroachment on breeding distributions of Brewer's Sparrows (Spizella breweri), Vesper Sparrows (Pooecetes gramineus), Green-tailed Towhees (Pipilo chlorurus), and Sage Thrashers (Oreoscoptes montanus) on Steens Mountain in southeastern Oregon. In 2000 we conducted fixed-radius point count surveys at 172 sites encompassing burned and unburned sagebrush habitat and a range of juniper densities. For each bird species we developed habitat models using local variables measured in the field and landscape variables derived …

Ferritin: Mechanistic Studies And Electron Transfer Properties, Bo Zhang Aug 2006

Ferritin: Mechanistic Studies And Electron Transfer Properties, Bo Zhang

Theses and Dissertations

Ferritins are ubiquitous iron storage proteins in living systems. Although much is known about the iron deposition process in ferritin and a mechanism has been developed, several important issues still remain unknown. One lingering question is the less than stoichiometric quantities of hydrogen peroxide detected in previous studies on animal ferritins. Extensive experimental data on identifying the species in competition for peroxide equivalents point to a surprising conclusion that H2O2 generated in the ferroxidase reaction is consumed by amine buffers that are commonly employed in in vitro ferritin studies, while non-nitrogen containing buffers, such as acetate, phosphate, and carbonate, do …

Genetic Considerations For The Conservation And Management Of Yellowstone Cutthroat Trout (Oncorhynchus Clarkii Bouvieri) In Yellowstone National Park, David J. Janetski Aug 2006

Genetic Considerations For The Conservation And Management Of Yellowstone Cutthroat Trout (Oncorhynchus Clarkii Bouvieri) In Yellowstone National Park, David J. Janetski

Theses and Dissertations

A key component to conservation is an accurate understanding of genetic subdivision within a species. Despite their ecological and economic importance, relatively little is understood about the genetic structuring of Yellowstone cutthroat trout in Yellowstone National Park. Here, we use traditional (Fst, Rst, Nm, and AMOVA) and modern (Bayesian assignment tests, coalescent theory, and nested clade analysis) analytical approaches to describe the population genetic subdivision of cutthroat trout spawning populations in Yellowstone Lake and to identify genetically distinct population segments throughout Yellowstone National Park. Evidence for restricted gene flow between spawning populations within Yellowstone Lake was detected using nested clade …

Across Arabia With Lehi And Sariah: “Truth Shall Spring Out Of The Earth”, Warren P. Aston Jul 2006

Across Arabia With Lehi And Sariah: “Truth Shall Spring Out Of The Earth”, Warren P. Aston

Journal of Book of Mormon Studies

Aston draws on his own research in Yemen and Oman as well as on the work of other scholars and researchers to explore two locations in the Book of Mormon account of Lehi’s journey through Arabia: Nahom and Bountiful. Preliminarily, Aston highlights Nephi’s own directional indications for each leg of the journey, considers the relevance of existing trade routes, and suggests relative durations of stops along the way. He reviews the research on the tribal area associated with Nahom, including the discovery of an altar dating to roughly 600 bc that bears the tribal name NHM—possibly the first archaeological evidence …

Refining The Spotlight On Lehi And Sariah, S. Kent Brown Jul 2006

Refining The Spotlight On Lehi And Sariah, S. Kent Brown

Journal of Book of Mormon Studies

Royal Skousen’s endeavor to recover the original text of the Book of Mormon is more complicated than it seems because it involves more than simply reproducing the original manuscript. Rather, what Skousen means by “original text” is the very language that appeared on the Urim and Thummim. Every subsequent step, such as Joseph’s reading, his scribes’ understanding and transcribing of that utterance, and Oliver Cowdery’s copying of the manuscript for the printer, exposed the text to the possibility of human subjectivity and error. This paper explains the nature and scope of Skousen’s monumental undertaking and presents some of the methods …

The Brightening Light On The Journey Of Lehi And Sariah, Daniel B. Mckinlay Jul 2006

The Brightening Light On The Journey Of Lehi And Sariah, Daniel B. Mckinlay

Journal of Book of Mormon Studies

Until now, nearly all commentaries on the Book of Mormon have focused mainly on issues of doctrine rather than beginning with the text itself. Royal Skousen’s critical text project does the opposite by treating the text itself on the word and phrase level. Skousen weighs nearly all possible evidence to deduce the events that may have led to the variations seen in the texts and to draw conclusions about which readings are most likely original. Some conclusions may surprise readers, but Skousen is more interested in candidly documenting what the texts reveal than in interpreting all the implications. Several lengthy …

An Archaeologist's View, Jeffrey R. Chadwick Jul 2006

An Archaeologist's View, Jeffrey R. Chadwick

Journal of Book of Mormon Studies

Royal Skousen’s most significant contribution to Book of Mormon scholarship, this paper states, is in openly and systematically detailing the thousands of variants that occur across two manuscripts and twenty editions and showing that these variations do not affect the message or validity of the book as a witness of Jesus Christ. Skousen’s work also offers new insights into the process of translating and publishing the Book of Mormon. Though the work of translation appears to have involved a number of different methods, we can nevertheless be sure that the Book of Mormon was translated by the “gift and power …

In Search Of Lehi's Trail—30 Years Later, Lynn M. Hilton Jul 2006

In Search Of Lehi's Trail—30 Years Later, Lynn M. Hilton

Journal of Book of Mormon Studies

Some critics of the Book of Mormon have suggested that Joseph Smith produced the book through a process known as “automatic writing,” a rapid flow of language claimed to be generated through paranormal means such as trance-like states or claimed communications with spirits. This paper presents an overview of some prominent claims of automatic writing and examines the historical and scientific evidence for the authenticity of at least some of these cases. After discussing the similarities between these works and the Book of Mormon, the paper outlines a number of features in the Book of Mormon that clearly differentiate it …

Weather Report From The Valley Of Lemuel, Wm. Revell Phillips Jul 2006

Weather Report From The Valley Of Lemuel, Wm. Revell Phillips

Journal of Book of Mormon Studies

In his effort to correct and preserve the original text of the Book of the Mormon, Royal Skousen has also increased our understanding of and appreciation for this volume of sacred scripture. Skousen’s close examination of the use of words and phrases throughout the book highlights its intertextuality and demonstrates that Book of Mormon authors were aware of and influenced by the words of previous authors. Moreover, restoring the original text helps clarify some vague constructions and should also caution us against putting too much emphasis on the exact wording of the present Book of Mormon. Skousen’s analysis of how …

Birds Along Lehi's Trail, Stephen L. Carr Jul 2006

Birds Along Lehi's Trail, Stephen L. Carr

Journal of Book of Mormon Studies

Royal Skousen’s work on his Book of Mormon critical text project demonstrates that he is an able textual critic who employs sound judgment and proven methods to uncover the original text of the Book of Mormon. In many cases, these decisions seem counterintuitive to untrained readers, but Skousen correctly applies the principle that a more awkward reading is most likely original. He also shows his ability to make conjectural emendations for which no direct textual evidence is available. In every case, Skousen clearly lays out his reasoning so that readers who disagree with his inferences can examine the evidence for …

Predicting Maize Yield, Nutrient Concentration And Uptake In P And K Fertilized Soils: Pressurized Hot Water And Other Alternatives To Mehlich I Extraction In Guatemala Soils, Heather Mae Hunsaker Jul 2006

Predicting Maize Yield, Nutrient Concentration And Uptake In P And K Fertilized Soils: Pressurized Hot Water And Other Alternatives To Mehlich I Extraction In Guatemala Soils, Heather Mae Hunsaker

Theses and Dissertations

The inaccessibility and cost of soil testing reduce effectiveness of fertilizer use on small-scale subsistence farms, and inadequate funding promotes adoption of soil tests in developing countries with minimal validation. For example, Mehlich-I extraction of phosphorus (P) currently used extensively in Guatemala may not be suitable for its broad range of soils. At least four alternatives are available but are relatively untested [Bray 1, Mehlich III, Olsen and pressurized hot water (PHW)]. Pressurized hot water is relatively simple and inexpensive, but is not yet tested against other extraction methods under variable P or potassium (K) fertilization levels. To determine whether …

Implementation Of A Life-Skill Centered Token Economy: The Experience Of A Peer Teacher, Joseph Fredrick Bellak Jul 2006

Implementation Of A Life-Skill Centered Token Economy: The Experience Of A Peer Teacher, Joseph Fredrick Bellak

Theses and Dissertations

This qualitative study examined how a peer teacher implemented, evaluated, and modified a life-skill centered token economy (LSCTE) model. The LSCTE is a hybrid of various components of token economy models that I have researched and observed. It is a classroom management model designed to help students participate in various roles/jobs that prepare them for community involvement and employment by giving them simulated experiences within a micro-society in the classroom. A peer teacher volunteered to implement the LSCTE. The findings demonstrated the participant's success with teaching children responsibility and accountability. Some of the benefits of the model reported by the …

Identification, Sequencing, Expression And Evolutionary Relationships Of The 11s Seed Storage Protein Gene In Chenopodium Quinoa Willd., Marie Renee Barrett Balzotti Jul 2006

Identification, Sequencing, Expression And Evolutionary Relationships Of The 11s Seed Storage Protein Gene In Chenopodium Quinoa Willd., Marie Renee Barrett Balzotti

Theses and Dissertations

Quinoa (Chenopodium quinoa) is an Andean crop adapted to harsh environmental conditions and containing a high and well-balanced protein composition. Two seed storage proteins, the 2S albumin and 11S globulin, are the major amino acid reservoirs for the developing seedling. An in-depth study of the genes encoding these proteins is necessary to understand the source of quinoa's protein quality. Our objectives include identification and sequencing of the 11S genomic and cDNA clones, analysis of 11S expression profiles in different quinoa accessions and evaluation of evolutionary relationships between the sequence of the 11S gene in quinoa and homologous genes in other …

The Memory Of The Body And Other Stories, Ryan Craig Shoemaker Jul 2006

The Memory Of The Body And Other Stories, Ryan Craig Shoemaker

Theses and Dissertations

This thesis is a collection of short stories written over the years 2002 to 2006. The short story is a genre that requires brevity. The short story writer, instead of treating the totality of human life, is forever, as Frank O'Connor suggests, selecting the point at which he can approach it. For this reason, unlike the novel, there is very little dallying in the short story. The short story writer, as the form requires, must make his world believable and coherent with only a minimum of words. Based on the experience of the actual author, the short story, like all …

Sequence Analysis Of Pmel17 As Candidate Gene For Causing Rat-Tail Syndrome In Cattle, Benjamin C. Hecht Jul 2006

Sequence Analysis Of Pmel17 As Candidate Gene For Causing Rat-Tail Syndrome In Cattle, Benjamin C. Hecht

Theses and Dissertations

Congenital hypotrichosis in cattle is commonly referred to as "rat-tail" syndrome and is characterized by a dilution of black coat color and morphological changes to the hair shaft and tail switch. Two loci are involved in the inheritance of the rat-tail phenotype, the "extension locus" (MC1R) and an unknown locus. In order to express the rat-tail phenotype the animal must inherit at least one black allele at MC1R and be heterozygous at the unknown locus. The rat-tail locus was previously mapped to an 8.7 cM region of Bos Taurus autosome (BTA) 5. Pmel17 is known to be involved in the …

An Awakened Sense Of Place: Thoreauvian Patterns In Willa Cather's Fiction, Breanne Grover Jul 2006

An Awakened Sense Of Place: Thoreauvian Patterns In Willa Cather's Fiction, Breanne Grover

Theses and Dissertations

The recent "greening" of Willa Cather Scholarship has initiated new conversations about Cather's use of and dependence on landscape in her fiction. Scholars have frequently noted Cather's reliance on landscape imagery, but this thesis suggests parallels between Cather's and Henry David Thoreau's use of awakening imagery and examines how such parallels work in Cather's environmental discussion of wilderness and environmental communities. There is little direct evidence linking the development of Cather to Thoreau, although their similar use of awakening imagery suggests they comment on similar environmental discussions through their writing, indicating that Cather deserves further attention as a nature writer. …

Tumor Associated Macrophages In A Mafia Mouse Model, Adrianne Brown Clifford Jul 2006

Tumor Associated Macrophages In A Mafia Mouse Model, Adrianne Brown Clifford

Theses and Dissertations

Recent evidence has shown the important role of macrophages in both tumor development and progression. To investigate the role of macrophages we used a mouse model known as MaFIA (Macrophage Fas Induced Apoptosis) mice that allows for the selective deletion of macrophages. Mice were given melanoma cells at various stages of depletion. Tumor mass was measured and organs were processed for flow cytometry to measure melanoma cell migration. The results show that mice receiving depletion treatment have larger tumor sizes and weights than those mice retaining their macrophage population. We detect metastasis in both the lung and kidney in both …

Phylogeographic Analyses Of Obligate And Facultative Cave Crayfish Species On The Cumberland Plateau Of The Southern Appalachians, Jennifer Elizabeth Buhay Jul 2006

Phylogeographic Analyses Of Obligate And Facultative Cave Crayfish Species On The Cumberland Plateau Of The Southern Appalachians, Jennifer Elizabeth Buhay

Theses and Dissertations

Cave systems and their unique biota are widely viewed as highly endangered, yet very little is known about basic life history, ecology, distributions, habitat requirements, and evolutionary relationships of subterranean species. The crux of the problem in cave studies is the assumption that traditionally defined morpho-species represent distinct evolutionary lineages. Convergence is exhibited in the morphologies of many animal groups, vertebrate and invertebrate, which leads to confusion in diagnosing species' boundaries, geographic distributions, gene flow routes, and imperilment. This dissertation research includes phylogeographic analyses of freshwater cave-dwelling crayfishes in the Southern Appalachians, a global hotspot of subterranean biodiversity. By examining …

From Cadillac To Chevy: Environmental Concern, Compromise And The Central Utah Project Completion Act, Adam R. Eastman

Theses and Dissertations

For the past century the federal government has been an active partner with state and local agencies to develop water supplies in the arid West. The last of the large-scale federal reclamation projects to be completed is the Central Utah Project or CUP. The CUP has generated considerable controversy throughout its history. The projects opponents have criticized its expense in terms of both dollars and environmental damage while others have worried about its impact on their water rights. Because of its cost and complexity, planning and construction have spanned decades. This has allowed individuals, organizations, and government agencies opportunity to …

Ecological Investigations Of Chukars In Western Utah, Randy T. Larsen Jul 2006

Ecological Investigations Of Chukars In Western Utah, Randy T. Larsen

Theses and Dissertations

This thesis presents three separate manuscripts in chapter format dealing with the ecology of Chukars (Alectoris chukar) in western North America. All three manuscripts have been formatted for publication in professional journals. Chapter one confirms discovery of ingested lead pellets in Chukars across a broad region of western Utah including all four western counties sampled. Prevalence rates were 1.9% (n=105) for crops and 10.7% (n=75) of gizzards showing no evidence of penetration wounds. Ingestion is likely related to grit size preferences that are consistent with common shot sizes. The second chapter describes watering patterns and water-site selection of Chukars. Chukars …

Pka As An Upstream Kinase For Lkb1/Strad/Mo25, Seth Taylor Herway Jul 2006

Pka As An Upstream Kinase For Lkb1/Strad/Mo25, Seth Taylor Herway

Theses and Dissertations

The LKB1/STRAD/MO25 complex (LSMK) has been identified as the major upstream kinase for AMP-activated protein kinase (AMPK). PKA phosphorylates LKB1 at the Ser428 residue in humans and Ser431 residue in mice. We investigated PKA as an upstream kinase for LSMK. LKB1 that had been incubated with PKA prior to incubation with AMPK experienced up to a 51% increase in AMPK Kinase activity compared to LKB1 alone (p < 0.05). When blocked with a PKA Inhibitor, the kinase effect of PKA on LKB1 was eliminated. Rat epitrochlearis muscle tissue incubated with epinephrine experienced no increase in AMPK activity compared with controls indicating that epinephrine does not cause AMPK activity in this type of tissue. In conclusion, phosphorylation by PKA can increase the AMPKK activity of LKB1-STRAD-MO25 in vitro. Because LKB1 has been found to be constitutively active, it is postulated that phosphorylation by PKA may act to enhance LKB1-AMPK interaction and thus achieve its effect.

Animism In Whitman: "Multitudes" Of Interpretations?, Rachelle Helene Woodbury Jul 2006

Animism In Whitman: "Multitudes" Of Interpretations?, Rachelle Helene Woodbury

Theses and Dissertations

Walt Whitman used animistic techniques in his poetry and prose, specifically "Song of the Redwood Tree," "Out of the Cradle Endlessly Rocking," and Specimen Days. The term animism can be traced to the Latin root of the word, anime, which connotes a "soul" or "vitality." So, when one is talking about animistic techniques, one is speaking of the (metaphoric or realistic) ensoulment of natural objects. In the wake of a growing global crisis modern scholarship has begun reexamining the implications of this belief; often it introduces ambiguities into an otherwise comfortable relationship of unquestioned human domination. In Specimen Days, Whitman …
