Capture Rates Of Reptiles And Amphibians On Black-Tailed Prairie Dog (Cynomys Ludovicianus) Colonies And On Uncolonized Prairie In Colorado, Bryon K. Shipley, Richard P. Reading, Brian J. Miller

Western North American Naturalist

Prairie dog eradication negatively affects dependent wildlife. Assessing the effects of prairie dog activities on reptiles and amphibians may depend upon the efficacy of trapping designs. We compared capture rates of reptiles and amphibians on black-tailed prairie dog (Cynomys ludovicianus) colonies and on adjacent uncolonized short-grass prairie, using funnel traps and pitfall traps with drift fences, as well as ground captures. We captured 152 reptiles and amphibians representing 10 species. We captured 51.3% of all reptiles and amphibians on colonies, compared to 48.7% from uncolonized sites. Overall, captures of reptiles and amphibians were similar on colonies and uncolonized …

Response Of Antelope Bitterbrush Shrubsteppe To Variation In Livestock Grazing, P. G. Krannitz

Western North American Naturalist

Shrubsteppe ecosystems in the Intermountain West have suffered extreme alteration from a variety of factors. Using a retrospective approach, I studied the effects of horse and cattle grazing at the northern edge of the range in southern British Columbia, Canada, where the shrubsteppe is not as heavily altered and ungrazed sites remain in areas dominated by antelope bitterbrush (Purshia tridentata). I measured shrub and understory cover at 10 sites that were either ungrazed, lightly grazed, or heavily grazed. Cover of antelope bitterbrush decreased with grazing, and cover of big sagebrush (Artemisia tridentata) increased with grazing intensity. …

Implications Of Polyploidy In The Host Plant Of A Dipteran Seed Parasite, Rebecca Hufft Kao

Western North American Naturalist

Although polyploidy can alter host plants in important ways (e.g., size, phenology, resource use, and ecological range), little is known about the effects of polyploidy-associated changes on plant-insect interactions. The presence of Campiglossa footeorum Novak (Diptera: Tephritidae) and its effect on its host plant Arnica cordifolia Hook. (Asteraceae) were monitored throughout Colorado, where triploids and tetraploids of the host plant occur. Campiglossa footeorum is more abundant in sites with more tetraploids and attacks tetraploids more than triploids. Polyploidy could be an important force shaping the current evolutionary trajectory of the plants and insects in this system. Campiglossa footeorum is intimately …

Leeches Of The Snake River In Idaho And Oregon: Paleodrainage Implications Of Mooreobdella Microstoma, Peter Hovingh, William H. Clark, John Keebaugh

Western North American Naturalist

Leech species of the mid-Snake River of Idaho and Oregon are described, and the distribution of the extant leech Mooreobdella microstoma Moore in the Snake River paleodrainage is delineated. Samples were collected from aquatic surveys in the Snake River using suction dredging by the Idaho Power Company and U.S. Bureau of Reclamation between 1995 and 2006. Supplementing these surveys, opportunities were provided for leech identification in water-quality analyses in Arizona and Wyoming and in other surveys in California, Oregon, Washington, and Idaho. Eight species of leeches were found in the Snake River surveys. Erpobdella parva Moore was the most widely …

Articles

Nanotechnology is regarded as one of the key technologies of the future and associated with high expectations by politics, science and economy. Artificially produced nanosized particles and nanoscale system components have new properties which are of importance for the development of new products and applications. Such new properties of materials and substances result from the special properties of surfaces and interfaces and in part, from the geometric shape of the material. In theory nanoparticles (NPs) can be produced from nearly any chemical; however, most NPs that are currently in use today have been made from transition metals, silicon, carbon (single-walled …

Protein Interactions With Mixed Poly(Ethylene Glycol)/Polyacrylic Acid Brushes, Zhenqing Li

All Theses

Tethered polymer chains that are grafted to a solid substrate by one chain end (polymer brushes) may be distinguished from other anchored polymer layers by the relatively high grafting densities gained. Potential uses of polymer brushes for interfacial modification to regulate interactions between proteins and substrates, such as drug delivery and protein separation, are widely recognized. Therefore, it is important to investigate interactions between proteins and surfaces modified with a polymer brush.
In this study, the 'grafting-to' method has been used to graft mixed poly(ethylene glycol) (PEG) and polyacrylic acid (PAA) brushes onto poly(glycidyl methacrylate) (PGMA)-modified silicon wafers/glass slides to …

Work-Related Outcomes Of Financial Stress: Relating Perceived Income Adequacy And Financial Strain To Job Performance And Worker Well-Being, Lindsay Ellen Sears

Dissertations and Theses

With the onset of globalization, the economic contexts and working conditions within many countries are changing, presenting new challenges' for governments, organizations, and workers. Amid these challenges, concerns about personal finances are prevalent among employees and detrimental to workers' health, well-being, and families. Research on how this financial stress affects employees at work is lacking.

In this thesis, I propose an appraisal-based model of financial stress whereby actual income and expenses are related to perceptions of income adequacy to afford wants and needs. These adequacy perceptions are, in turn, related to financial strain, representing a heightened negative affective state regarding …

The Neuropsychological Endophenotype Of Specific Language Impairments And Autism Spectrum Disorders: Category Or Continuum?, Heather M. Anson

Master's Theses and Doctoral Dissertations

The primary goal of this investigation was to illuminate variables of the specific language impairment (SLI) and autism spectrum disorders (ASD) neuropsychological endophenotypes and to clarify the nature of overlap between SLI and ASD. Group differences in cognitive functioning, epidemiological factors including proband comorbidity and health problems, and familial data in 39 SLI children and 89 ASD children who presented for clinical evaluation at Henry Ford Health System in Detroit were examined by retrospective chart review.

Cognitive data revealed that ASD probands performed more poorly on tests of perceptual-motor functioning and had higher rates of pragmatic language deficits than SLI …

Fluorescence Tomography Characterization For Sub-Surface Imaging With Protoporphyrin Ix, Dax Kepshire, Scott C. Davis, Hamid Dehghani, Keith D. Paulsen, Brian W. Pogue

Dartmouth Scholarship

Optical imaging of fluorescent objects embedded in a tissue simulating medium was characterized using non-contact based approaches to fluorescence remittance imaging (FRI) and sub-surface fluorescence diffuse optical tomography (FDOT). Using Protoporphyrin IX as a fluorescent agent, experiments were performed on tissue phantoms comprised of typical in-vivo tumor to normal tissue contrast ratios, ranging from 3.5:1 up to 10:1. It was found that tomographic imaging was able to recover interior inclusions with high contrast relative to the background; however, simple planar fluorescence imaging provided a superior contrast to noise ratio. Overall, FRI performed optimally when the object was located on or …

The Relationship Between Individual Differences In Cognitive, Social And Personality Development And The Increase In Complexity Of Children’S Alcohol Expectancies, Nicole M. Bekman

USF Tampa Graduate Theses and Dissertations

The current study aimed to simultaneously examine cognitive, social and personality development in a cross-sectional sample of 3^rd, 4^th and 5^th grade children to explore the interplay among these processes and how they relate to changes in children's understanding of alcohol. To replicate previous work, this study comprehensively examined relative increases in types of expectancies as a function of development. Results demonstrated that children in higher grades held more positive, negative and sedating expectancies of alcohol and positive alcohol expectancies increased more than negative alcohol expectancies. Improved performance on cognitive measures were associated with positive alcohol …

Evangelical Students In American Higher Education, Joseph C. Fox

USF Tampa Graduate Theses and Dissertations

This qualitative study explored the perceptions of evangelical freshmen students attending the University of Texas at Arlington and the University of Texas at Dallas during the spring semester of 2006 in the context of student alienation. The purpose of this study was to explore the possibility that evangelicals attending secular universities were perceiving alienation through their interactions with their universities. It was hypothesized that the modern university, having evolved into its present naturalistic worldview condition, might prove alienating to evangelicals from a worldview standpoint. Assuming the possibility that alienation might prove to be a reality for evangelicals, the subordinate purposes …

A Review Of The Genus Chortophaga (Orthoptera: Acrididae) Among Nebraska Populations: Questioning The Validity Of Chortophaga Australior Rehn And Hebard, Mathew L. Brust, W. Wyatt Hoback, Robert J. Wright

Department of Entomology: Faculty Publications

Chortophaga australior Rehn and Hebard (Orthoptera: Acrididae) is considered a species distinct from Chortophaga viridifasciata (DeGeer). Collections across Nebraska have shown that the characters used to separate these two species are inconsistent and that the average state of these characters appears to be related to the time of the season during which the adults are collected. Until further study clarifies the status of C. australior, we suggest that its specific status be considered questionable.
