Promoting Social And Emotional Learning In Second Grade Students: A Study Of The Strong Start Curriculum, Paul Caldarella, Lynnette Christensen, Thomas J. Kramer, Kalli Kronmiller Aug 2009

Promoting Social And Emotional Learning In Second Grade Students: A Study Of The Strong Start Curriculum, Paul Caldarella, Lynnette Christensen, Thomas J. Kramer, Kalli Kronmiller

Faculty Publications

The promotion of social and emotional learning (SEL) in schools may help prevent emotional and behavioral problems of students. This study evaluated the effects of a SEL curriculum, Strong Start, on the social-emotional competence of 26 second grade students, using a quasi-experimental, non-equivalent control group design. Results revealed statistically significant and meaningful improvements in teacher ratings of students’ internalizing and peer-related prosocial behaviors, particularly for students at greater risk. Conversely, control group students experienced significant worsening of internalizing behaviors and decreased levels of peer-related prosocial behaviors. No changes were reported in externalizing behaviors for either group. Treatment integrity and social …

Differential Mortality Drives Life-History Evolution And Population Dynamics In The Fish Brachyrhaphis Rhabdophora, Jerald B. Johnson, J. Jaime Zuniga-Vega Aug 2009

Differential Mortality Drives Life-History Evolution And Population Dynamics In The Fish Brachyrhaphis Rhabdophora, Jerald B. Johnson, J. Jaime Zuniga-Vega

Faculty Publications

Life-history theory predicts that populations experiencing different levels of extrinsic mortality will evolve divergent reproductive strategies. Previous work in the live bearing fish Brachyrhaphis rhabdophora shows that individuals from populations that occur with piscivorous fish mature earlier and at smaller sizes and have more and smaller offspring than fish from populations without predators. However, until now, there have been no data to demonstrate that differences in mortality rates actually exist between predator and predator free sites. Here we present the results of a serial mark-recapture field study designed to estimate mortality rates in natural populations of B. rhabodophora from Costa …

Cis-Regulatory Sequence And Co-Regulatory Transcription Factor Functions In Erα-Mediated Transcriptional Repression, Richard Leroy Smith Jul 2009

Cis-Regulatory Sequence And Co-Regulatory Transcription Factor Functions In Erα-Mediated Transcriptional Repression, Richard Leroy Smith

Theses and Dissertations

Estrogens exert numerous actions throughout the human body, targeting healthy tissue while also enhancing the proliferative capacity of breast cancers. Estrogen signaling is mediated by the estrogen receptor (ER), which binds DNA and ultimately affects the expression of adjacent genes. Current understanding of ER-mediated transcriptional regulation is mostly limited to genes whose transcript levels increase following estrogen exposure, though recent studies demonstrate that direct down-regulation of estrogen-responsive genes is also a significant feature of ER action. We hypothesized that differences in cis-regulatory DNA was a factor in determining target gene expression and performed computational and experimental studies to test this …

Physiological Assessment Of Chenopodium Quinoa To Salt Stress, Arturo Jason Morales Jul 2009

Physiological Assessment Of Chenopodium Quinoa To Salt Stress, Arturo Jason Morales

Theses and Dissertations

The physiological responses to salt stress were measured in Chenopodium quinoa. In a greenhouse experiment, salt water was applied to the quinoa varieties, Chipaya and KU-2, and to the model halophyte Thellungiella halophila to assess their relative responses to salt stress. Height and weight data from a seven-week time course demonstrated that both cultivars exhibited greater tolerance to salt than T. halophila. In a growth chamber experiment, three quinoa cultivars, Chipaya, Ollague, and CICA 17 were hydroponically grown and physiological responses were measured with four salt treatments. Tissues collected from the growth chamber treatments were used to obtain …

Beyond The Walls: The Easter Processional On The Exterior Frescos Of Moldavian Monastery Churches, Mollie Elizabeth Mcvey Jul 2009

Beyond The Walls: The Easter Processional On The Exterior Frescos Of Moldavian Monastery Churches, Mollie Elizabeth Mcvey

Theses and Dissertations

During the sixteenth century, the princes of Moldavia, a region of modern Romania, built many churches and monasteries. These churches followed the typical Byzantine style by placing detailed frescos on the interior walls, but some of the Moldavian churches took that tradition even further and expanded the frescos to the façade. This thesis argues that these exterior images were used to enhance the Easter processionals that occurred around the churches. While most scholars explain this phenomenon as propaganda or a cry for help against the Ottoman Empire, a new interpretation is offered here. It discusses how the exterior scenes on …

Interpreting The Sacred In As You Like It: Reading The "Book Of Nature" From A Christian, Ecocritical Perspective, Candice Dee Wendt Jul 2009

Interpreting The Sacred In As You Like It: Reading The "Book Of Nature" From A Christian, Ecocritical Perspective, Candice Dee Wendt

Theses and Dissertations

Since the advent of the environmental crisis, some writers have raised concerns with the moral influence of Christian scripture and interpretive traditions, such as the medieval book of nature, a hermeneutic in which nature and scripture are "read" in reference to one another. Scripture, they argue, has tended to stifle sacred relationships with nature as a non-human other. This thesis argues that such perspectives are reductive of the sacred quality of scripture. Environmental perspectives should be concerned with the desacralization of religious texts in addition to nature. Chapter one suggests that two questions surrounding the medieval book of nature's history …

Portrayal Of Older People In Disney Live Action Films From The 1990s And 2000s, Jennifer Gail Martin Jul 2009

Portrayal Of Older People In Disney Live Action Films From The 1990s And 2000s, Jennifer Gail Martin

Theses and Dissertations

Children as young as three years old are scared of the idea of growing old, and negative stereotypes about older people have started to develop by the time children enter elementary school. Negative stereotyping of older characters has been found to be prevalent in all forms of media. Because children use media to figure out who they are and what the world is like, this study looks at some of the most popular films of the past two decades aimed toward children. This study is a content analysis of older major and minor characters from the 60 top grossing Disney …

Phytogeography And Floristics Of Pinyon-Juniper Woodlands In Northern Arizona, Kyle Christie Jul 2009

Phytogeography And Floristics Of Pinyon-Juniper Woodlands In Northern Arizona, Kyle Christie

Western North American Naturalist

This study assesses the floristic diversity and affinities of pinyon-juniper (PJ) woodlands in northern Arizona at 2 different scales: regionally within the context of North American floristic patterns and locally within the 2500-m elevation gradient of the San Francisco Volcanic Field (SFVF). An analysis based upon 245 North American floras indicates that the PJ woodlands of the SFVF share strong affinities with the adjacent Colorado Plateau and Apachian floristic elements but also show high floristic similarity to the Great Plains. Data suggest that mid-elevation woodlands of the Colorado Plateau share floristic affinities with the Great Plains that are as strong …

Bats Along The Republican River And Its Tributaries In Southwestern Nebraska: Distribution, Abundance, And Reproduction, Matthew R. Serbousek, Keith Geluso Jul 2009

Bats Along The Republican River And Its Tributaries In Southwestern Nebraska: Distribution, Abundance, And Reproduction, Matthew R. Serbousek, Keith Geluso

Western North American Naturalist

Thirteen species of bats occur in Nebraska, but limited information is available on those inhabiting southwestern parts of the state. We investigated the distribution, abundance, and reproductive activity of bats in 5 counties in extreme southwestern Nebraska (Chase, Hays, Dundy, Hitchcock, and Red Willow). From April 2007 to April 2008, we deployed mist nets on 15 occasions at 8 localities over the Republican River and its tributaries. We captured 100 individuals representing 5 species, including the evening bat (Nycticeius humeralis), eastern red bat (Lasiurus borealis), hoary bat (Lasiurus cinereus), big brown bat (Eptesicus …

Predator-Specific Mortality Of Pronghorn On Yellowstone's Northern Range, Kerey K. Barnowe-Meyer, P. J. White, Troy L. Davis, John A. Byers Jul 2009

Predator-Specific Mortality Of Pronghorn On Yellowstone's Northern Range, Kerey K. Barnowe-Meyer, P. J. White, Troy L. Davis, John A. Byers

Western North American Naturalist

Yellowstone National Park supports a small population (<300) of pronghorn (Antilocapra americana). Some individuals migrate during summer to areas characterized by reduced visibility, mixed habitat types, and a diverse predator community. Across areas selected by migratory and nonmigratory pronghorn, we documented cause-specific mortality of adults and fawns and assessed relative risk of predation by various predators. Coyotes (Canis latrans) accounted for 56% of adult predation and up to 79% of fawn predation. Cougars (Puma concolor) and wolves (Canis lupus) accounted for additional predation of adults, while cougars, black bears (Ursus americanus), and Golden …

Genetics Of Allopatric Populations Of The Montane Vole (Microtus Montanus) And Mogollon Vole (Microtus Mogollonensis) In The American Southwest, Jennifer K. Frey Jul 2009

Genetics Of Allopatric Populations Of The Montane Vole (Microtus Montanus) And Mogollon Vole (Microtus Mogollonensis) In The American Southwest, Jennifer K. Frey

Western North American Naturalist

Variation at 21 allozyme loci and 10 restriction enzymes within the mitochondrial DNA control region was assessed among 3 allopatric populations of montane vole (Microtus montanus) in the American Southwest. Among populations of M. montanus, the population from the White Mountains, Arizona, was most genetically divergent. Genetic and biogeographic evidence supported recognition of the White Mountains population as a distinct subspecies, M. m. arizonensis. Results also supported recognition of the Mogollon vole (Microtus mogollonensis) as distinct from the Mexican vole (Microtus mexicanus).

Captures Of Crawford's Gray Shrews (Notiosorex Crawfordi) Along The Rio Grande In Central New Mexico, Alice Chung-Maccoubrey, Heather L. Bateman, Deborah M. Finch Jul 2009

Captures Of Crawford's Gray Shrews (Notiosorex Crawfordi) Along The Rio Grande In Central New Mexico, Alice Chung-Maccoubrey, Heather L. Bateman, Deborah M. Finch

Western North American Naturalist

We captured >2000 Crawford's gray shrews (Notiosorex crawfordi) in a riparian forest mainly consisting of cottonwoods (Populus deltoides) along the Rio Grande in central New Mexico. Little has been published about abundance and habitat of Crawford's gray shrew throughout its distributional range. During 7 summers, we captured shrews in pitfall traps at 13 study sites in Bernalillo, Valencia, and Socorro counties. Capture rates of shrews were greatest in August and September, and we did not detect a response of shrews to restoration treatments that removed nonnative plants from riparian forests. Results from our study indicate that …

Factors Influencing Selection Of Road Culverts As Winter Roost Sites By Western Burrowing Owls, Damon Williford, Marc C. Woodin, Mary Kay Skoruppa Jul 2009

Factors Influencing Selection Of Road Culverts As Winter Roost Sites By Western Burrowing Owls, Damon Williford, Marc C. Woodin, Mary Kay Skoruppa

Western North American Naturalist

The conversion of coastal prairie to farmland in southern Texas has drastically reduced the number of available animal burrows, thereby forcing western Burrowing Owls (Athene cunicularia hypugaea) wintering in southern Texas to use nontraditional roost sites such as roadside culverts. We studied factors influencing the selection of road culverts as roost sites by Burrowing Owls by comparing characteristics of 34 occupied and 100 unoccupied culverts. All occupied culverts were in agricultural habitat. Culverts with small diameters (≤16 cm) and those with an east–west orientation were occupied by Burrowing Owls in greater proportions than were culverts with larger diameters …

Selective Herbivory By The Desert Woodrat (Neotoma Lepida) On Joshua Trees (Yucca Brevifolia), Monte P. Sanford, Nancy Huntly Jul 2009

Selective Herbivory By The Desert Woodrat (Neotoma Lepida) On Joshua Trees (Yucca Brevifolia), Monte P. Sanford, Nancy Huntly

Western North American Naturalist

We studied herbivory by the desert woodrat (Neotoma lepida) on Joshua trees (Yucca brevifolia) in the Mojave Desert to determine whether N. lepida fed selectively based on leaf nitrogen content. We measured leaf nitrogen content and the location and amount of herbivory by woodrats on Y. brevifolia trees in southwestern Utah, USA. Neotoma lepida removed the outer tips of leaves (1/3 to 2/3 of total leaf length) but left leaf bases, which had lower nitrogen content, uneaten. Herbivory by N. lepida also was concentrated on rosettes that were oriented south, and these had significantly higher nitrogen …

Genetic Structuring At A Fine Scale In The Russet-Crowned Motmot (Momotus Mexicanus) In A Tropical Dry Forest In Central Mexico, Dolores Reyes, Raúl E. Alcalá, Dulce Arias, Marcela Osorio-Beristain Jul 2009

Genetic Structuring At A Fine Scale In The Russet-Crowned Motmot (Momotus Mexicanus) In A Tropical Dry Forest In Central Mexico, Dolores Reyes, Raúl E. Alcalá, Dulce Arias, Marcela Osorio-Beristain

Western North American Naturalist

Because of their high dispersal abilities, birds are expected to manifest marked genetic structuring only at relatively large geographic scales. However, it is not well known how factors like nest site fidelity in a largely resident species could limit gene flow and increase genetic structuring in birds. In this study we use RAPD markers to estimate genetic structuring in a strongly sedentary species of the American tropics, the Russet crowned Motmot (Momotus mexicanus), within a tropical dry forest in central Mexico. Genetic structuring was assessed among 3 populations separated by a mean distance of only 25 km. We …

Ant Assemblages In Intact Big Sagebrush And Converted Cheatgrass-Dominated Habitats In Tooele County, Utah, Steven M. Ostoja, Eugene W. Schupp, Kelly Sivy Jul 2009

Ant Assemblages In Intact Big Sagebrush And Converted Cheatgrass-Dominated Habitats In Tooele County, Utah, Steven M. Ostoja, Eugene W. Schupp, Kelly Sivy

Western North American Naturalist

Biological invasions are one of the greatest threats to native species in natural ecological systems. One of the most successful invasive species is Bromus tectorum L. (cheatgrass), which is having marked impacts on native plant communities and ecosystem processes. However, we know little about the effects of this invasion on native animal species in the Intermountain West. Because ants have been used to detect ecological change associated with anthropogenic land use, they seem well suited for a preliminary evaluation of the consequences of cheatgrass-driven habitat conversion. In our study, we used pitfall traps to assess ant community assemblages in intact …

American Pikas Inhabit Low-Elevation Sites Outside The Species' Previously Described Bioclimatic Envelope, William G. Simpson Jul 2009

American Pikas Inhabit Low-Elevation Sites Outside The Species' Previously Described Bioclimatic Envelope, William G. Simpson

Western North American Naturalist

It has been suggested that Nearctic pikas (Ochotona spp.) are good biogeographic indicators of regions containing rocky, mesic, and cool habitat characterized by long winters and short summers. I examined whether populations of pikas inhabiting distinct low-elevation locales (121–255 m) are faithfully restricted to long-winter and short-summer conditions by monitoring the climate associated with American pikas (Ochotona princeps) in the southern part of the Columbia River Gorge, Oregon. Ambient air temperatures and weather conditions in the vicinity of 4 pika-occupied rockslides were monitored with remote temperature loggers and weather stations from June 2000 to June 2001. Temperatures …

Range Expansion Of The Collared Peccary In New Mexico: Potential For Interactions Between Historically Separate Subspecies, Louis J. Lamit, Marguerite N. Hendrie Jul 2009

Range Expansion Of The Collared Peccary In New Mexico: Potential For Interactions Between Historically Separate Subspecies, Louis J. Lamit, Marguerite N. Hendrie

Western North American Naturalist

The collared peccary (Tayassu tajacu) is undergoing range expansion in the southwestern United States. Here we report sightings of the collared peccary from locations outside the known ranges of either of the subspecies, T. t. sonoriensis and T. t. angulatus, in south central New Mexico. Sightings include multiple individuals of different ages. This indicates that the collared peccary is expanding into previously unoccupied areas between the documented ranges of the 2 subspecies. We suggest that the possibility of gene flow between the 2 historically separate subspecies may have important evolutionary consequences.

Camel Spider (Solifugae) Use Of Prairie Dog Colonies, B. D. Duval, W. G. Whitford Jul 2009

Camel Spider (Solifugae) Use Of Prairie Dog Colonies, B. D. Duval, W. G. Whitford

Western North American Naturalist

Solifugids (camel spiders) are widespread throughout arid regions of western North America and are thought to be important in structuring desert arthropod communities. Despite the ubiquity of camel spiders, little is known about their ecology. Black-tailed prairie dogs (Cynomys ludovicianus) are also widespread in western North America and are important ecosystem engineers, but they have been reduced in extent because of human activity. Here we report significantly greater numbers of camel spiders on black-tailed prairie dog colonies in southern New Mexico. The difference in vegetation structure created by prairie dog activity is likely the reason for the increased …

Adjusting The Rearview Mirror: Higher Level Reflection Strategies In First-Year Composition, Jessica Ann Green Jul 2009

Adjusting The Rearview Mirror: Higher Level Reflection Strategies In First-Year Composition, Jessica Ann Green

Theses and Dissertations

Part of the curriculum in many composition classrooms contains a reflection component where students are required to think back over their writing and discuss strengths and weaknesses. Yet many of the reflections that students write fall short of the purpose of reflection when students fail to analyze their writing practices or to make future goals for themselves, a problem that occurs when higher level reflection strategies are not taught and practiced in the classroom. When students are taught to use reflection as a way to critically evaluate their writing, to make connections between class assignments and course objectives, and to …

Co-Occurrence With A Congeneric Species Predicts Life History And Morphological Diversification In The Mexican Livebearing Fish Poelicopsis Baenschi, Laura E. Scott Jul 2009

Co-Occurrence With A Congeneric Species Predicts Life History And Morphological Diversification In The Mexican Livebearing Fish Poelicopsis Baenschi, Laura E. Scott

Theses and Dissertations

Understanding why some species coexist and others do not remains one of the fundamental challenges of ecology. While several lines of evidence suggest that closely related species are unlikely to occupy the same habitat because of competitive exclusion, there are many cases where closely related species do co-occur. Research comparing sympatric and allopatric populations of co-occurring species provides a framework to understand the role of phenotypic diversification in species coexistence. In this study I focus on the livebearing fish Poeciliopsis baenschi and ask if differences in phenotypic traits among populations can be explained by the presence or absence of the …

Literary Case Histories And Medical Narratives In Nineteenth-Century Britain, Travis Wade Austin Jul 2009

Literary Case Histories And Medical Narratives In Nineteenth-Century Britain, Travis Wade Austin

Theses and Dissertations

Literature and medicine are not usually seen as related disciplines, but scholars have already begun producing fruitful scholarship regarding historical and aesthetic interactions between them. This thesis adds to that scholarship by examining medicine and literature in nineteenth-century Britain. More specifically, Thomas De Quincey's Confessions of an English Opium-Eater and Robert Louis Stevenson's Strange Case of Dr. Jekyll and Mr. Hyde both use nineteenth-century medical case conventions to tell their stories. Furthermore, because both works deal with addiction, divided selves, and the power that physical substances can have on morality and character, these two works provide an excellent comparison coming …

The Grass Seed Pathogen Pyrenophora Semeniperda As A Biocontrol Agent For Annual Brome Grasses, Thomas E. Stewart Jul 2009

The Grass Seed Pathogen Pyrenophora Semeniperda As A Biocontrol Agent For Annual Brome Grasses, Thomas E. Stewart

Theses and Dissertations

Bromus tectorum and other annual brome grasses have invaded many ecosystems of the western United States, and because of an annual-grass influenced alteration of the natural fire cycle on arid western range lands near monocultures are created and conditions in which the native vegetation cannot compete are established. Each year thousands of hectares become near monocultures of annual brome grasses. Pyrenophora semeniperda, a generalist seed pathogen of annual grasses, shows major potential as a possible mycoherbicide that could help in reducing the monocultures created by annual grasses. The purpose of this research was to identify the requirements for isolating …
