Chemistry Of Cirsium And Carduus: A Role In Ecological Risk Assessment For Biological Control Of Weeds?, Ingrid E. Jordon-Thaden, Svata M. Louda
Chemistry Of Cirsium And Carduus: A Role In Ecological Risk Assessment For Biological Control Of Weeds?, Ingrid E. Jordon-Thaden, Svata M. Louda
School of Biological Sciences: Faculty Publications
Prediction of host plant range and ecological impact of exotic phytophagous insects, such as insects for classical biological control of weeds, represents a major challenge. Recently, the flowerhead weevil (Rhinocyllus conicus Fröl.), introduced from Europe into North America to control exotic thistles (Carduus spp.), has become invasive. It feeds heavily on some, but not all species of native North American thistles (Cirsium spp.). We hypothesized that such non-target use among native plants could be better predicted by knowledge of characteristic chemical profiles of secondary compounds to supplement the results of host specificity testing. To evaluate this hypothesis, …

The Sibley Field Guide to Birds of Eastern North America and The Sibley Field Guide to Birds of Western North America by David Allen Sibley (Knopf, 2003, $19.95 each).
Sibley has taken up the mantle of Roger Tory Peterson, who gave birth to the modem avian field guide in the 1930s and guided its development for more than half a century. I think that Roger would be pleased with the direction that David Sibley is taking it. The Sibley guides are so good that further editions are a dead certainty. As with the Peterson guides, I will likely …

The Effect Of Unilateral Partial Edentulism To Muscle Thickness, Gozlem Koca-Ceylan, Nergiz Taskaya-Yilmaz, Ahmet U. Guler, Lutfi Incesu, Tolga Aksoz
Saudi Medical Journal
OBJECTIVE: Teeth and muscles play a very important role for occlusal equilibrium and function. When tooth loss begins, it may also affect the function of the muscle tissues. METHODS: The thickness of the masseter and anterior temporalis muscles were measured bilaterally in 30 healthy fully dentate adults and in 30 unilateral edentulous patients by using ultrasonographic imaging. All scans were carried out by the same radiologist to eliminate the inter-observer difference, using a real time scanner (Toshiba SSA- 270 A Japan). A 7.5 MHz linear transducer was used. The transducer was held against the cheek with light pressure. The effect …

The purpose of this data set was to compile body mass information for all mammals on Earth so that we could investigate the patterns of body mass seen across geographic and taxonomic space and evolutionary time. We were interested in the heritability of body size across taxonomic groups (How conserved is body mass within a genus, family, and order?), in the overall pattern of body mass across continents (Do the moments and other descriptive statistics remain the same across geographic space?), and over evolutionary time (How quickly did body mass patterns iterate on the patterns seen today? Were the Pleistocene …

Phylogenetic hypothesis of 23 populations corresponding to 18 species of the digenean Haematoloechus from America, Europe, and Africa, based on ribosomal DNA 28S partial sequences (~890 bp), is presented. Genetic divergence between the in-group and the out-groups ranged from 9.7 to 14.5% and within the in-group, from 0.9 to 12.2%. Eight most parsimonious trees 569 steps long were obtained, with a consistency index of 72%. Groups in the tree are not congruent with those in previous classification schemes of species in the genus, based on a small number of morphological characters. For this subset of Haematoloechus,/i> species, plesiomorphic hosts are …
African American Fugitive Slaves And Freemen In Matamoros, Tamaulipas, 1820–1865, John C. Gassner
African American Fugitive Slaves And Freemen In Matamoros, Tamaulipas, 1820–1865, John C. Gassner
Theses and Dissertations - UTB/UTPA
In the years leading up to the American Civil War, northeastern Mexico became a destination for fugitive slaves and African American freemen seeking refuge from the oppressive conditions caused by the expansion of the slave-based cotton economy in the southern United States and Texas. The geographic position of Matamoros, as well as social, economic and political changes in Mexico and the United States, made it one of the main destinations for African American emigrants leaving the Texas and other parts of the United States. This thesis examines the factors that caused different elements of African American fugitives slaves and freemen …

Synthesis Of Peptides With Hydroxamic Acid Side Chain Appendages., Yingchuan Susan Sun 1975-
Synthesis Of Peptides With Hydroxamic Acid Side Chain Appendages., Yingchuan Susan Sun 1975-
Electronic Theses and Dissertations
Chapter 1 detailed the synthesis method of hydroxamate peptides derivatives of pentapeptide Ac-PHSXX\'-N-NH2 by solid phase hydroxamate peptide synthesis method. The glutamic acid/aspartic acid side chain was modified to hydroxamic acid by on resin N-C coupling. The hydroxamate benzyl protecting group was removed during HF cleavage. In Chapter 2 a novel multiple hydroxamic acid peptide siderophore was prepared and the metal binding activity of these peptides was studied by ESI-MS and MS/MS. Siderophore peptide Ac-Gly1-Glu2(NHOH)-D-Pro3-Gly4-Glu5(NHOH)-D-Pro6-NH2 was found to have significant preference to Fe(III) over Zn(II) and Ni(II), while the natural peptide analogue Ac-Gly1-Glu2-D-Pro 3-Gly4-Glu5-D-Pro6-NH2 did not show any obvious preference …
Functional Proteomic Analysis Of The Myocardial Pkcepsilon Subproteome Pkcepsilon-Akt-Enos Signaling Modules And During., Jun Zhang
Electronic Theses and Dissertations
Ischemic heart disease is the leading cause of mortality and morbidity in Western societies. Thus, understanding the molecular mechanisms to reduce myocardial ischemia and limit infarction size are of great importance. Ample evidence has shown that protein kinase C epsilon (PKCepsilon) play an essential role in the genesis of cardioprotection. In particular, our laboratory has shown that activation of PKCepsilon in the heart is sufficient to significantly reduce myocardial infarction due to coronary artery occlusion. However, the molecular mechanism responsible for PKCepsilon-induced cardioprotection remain unclear. Recently, functional proteomic analysis have demonstrated that PKCepsilon forms signaling complexes with various of proteins, …
Oxygen Toxicity And Mitochondrial Metabolism., Jian Li 1974-
Oxygen Toxicity And Mitochondrial Metabolism., Jian Li 1974-
Electronic Theses and Dissertations
Oxygen is critical to aerobic metabolism, but hyperoxia is cytostatic and cytocidal. The precise mechanisms involved in hyperoxic cell injury remain incompletely understood although there is substantial support for the possibility that hyperoxia increases the 'leak' of electrons from the mitochondrial electron transport chain and the resulting increased generation of reactive oxygen species (ROS) might explain the toxic effects of high oxygen. To evaluate the possible role of mitochondria in oxygen toxicity, we used cloned HeLa cells having no functional mitochondria (?° cells) as a model. In contrast to wild-type HeLa cells, ?° cells survive and grow in 80% O2 …
Regulation Of Na,K-Atpase Activity By Tyrosine Phosphorylation In Lens Cells., Larry Darko Bozulic 1974-
Regulation Of Na,K-Atpase Activity By Tyrosine Phosphorylation In Lens Cells., Larry Darko Bozulic 1974-
Electronic Theses and Dissertations
Na,K-ATPase is essential for the regulation of cytoplasmic Na+ and K+ levels in lens cells. Insufficient Na,K-ATPase activity is associated with cataract formation. Based on earlier studies in which Src-tyrosine kinase inhibitors were found to suppress Na,K-ATPase activity changes that occur in response to either thrombin, endothelin, or dopamine, I hypothesize that regulation of Na,K-ATPase activity might occur through phosphorylation of the Na,K-ATPase a1 (catalytic) subunit by Src-family tyrosine kinases. Here, I tested the influence of Src-kinase family members on tyrosine phosphorylation and Na,K-ATPase activity in membrane material isolated from porcine lens epithelium. Western blot studies indicated the expression of …
When Personality Traits Need A Frame Of Reference: Enhancing The Predictive Validity Of Non-Cognitive Measures, Andrew David English
When Personality Traits Need A Frame Of Reference: Enhancing The Predictive Validity Of Non-Cognitive Measures, Andrew David English
Theses and Dissertations
The reconsideration of personality among personnel specialists is partly due to the discovery of the five-factor model of personality or the "Big Five" (Costa, 1996). In the years following the acceptance of this taxonomy, several researchers have examined the relationship of the "Big Five" personality traits to numerous job performance criteria. Research has show:n that personality testing can contribute significant incremental validity over that of cognitive ability and skills (Neuman & Wright, 1999). The issues of trait consistency and the faking of personality measures have divided researchers in regards to how detrimental the effects of each are. The results of …

Superior Protection Against Malaria And Melanoma Metastases By A C-Glycoside Analogue Of The Natural Killer T Cell Ligand Α-Galactosylceramide, John Schmieg, Guangli Yang, Richard W. Franck, Moriya Tsuji
Publications and Research
α-Galactosylceramide (α-GalCer) is a glycolipid that stimulates natural killer T cells to produce both T helper (Th) 1 and Th2 cytokines. This property enables α-GalCer to ameliorate a wide variety of infectious, neoplastic, and autoimmune diseases; however, its effectiveness against any one disease is limited by the opposing activities of the induced Th1 and Th2 cytokines. Here, we report that a synthetic C-glycoside analogue of α-GalCer, α-C-galactosylceramide (α-C-GalCer), acts as natural killer T cell ligand in vivo, and stimulates an enhanced Th1-type response in mice. In two disease models requiring Th1-type responses for control, namely malaria and melanoma metastases, α-C-GalCer …
The Perpetuation Of The Fairy Tale Narrative In Popular Film: A Textual Analysis, Audra D. Van Hoff
The Perpetuation Of The Fairy Tale Narrative In Popular Film: A Textual Analysis, Audra D. Van Hoff
Theses and Dissertations
Communication media have an enormous impact on our perceptions of the world; therefore, I believe it is crucial to examine these media as a cultural text in order to gain an understanding of how producers of the text create meaning through critical elements found in the text. More closely, it is important to understand how these texts can represent things, such as gender and culture. Specifically, this thesis explores the dominate themes of a fairy tale narrative in contemporary film. It deconstructs the character and plot structure of five films from different genres. It then goes on to look at …

Genetic Locus And Structural Characterization Of The Biochemical Defect In The O-Antigenic Polysaccharide Of The Symbiotically Deficient Rhizobium Etli Mutant, Ce166, Lennart Scott Forsberg, K. Dale Noel, Jodie M. Box, Russell W. Carlson
Biological Sciences Faculty Research and Publications
The O-antigen polysaccharide (OPS) of Rhizobium etli CE3 lipopolysaccharide (LPS) is linked to the core oligosaccharide via an N-acetylquinovosaminosyl (QuiNAc) residue. A mutant of CE3, CE166, produces LPS with reduced amounts of OPS, and a suppressed mutant, CE166α, produces LPS with nearly normal OPS levels. Both mutants are deficient in QuiNAc production. Characterization of OPS from CE166 and CE166α showed that QuiNAc was replaced by its 4-keto derivative, 2-acetamido-2,6-dideoxyhexosyl-4-ulose. The identity of this residue was determined by NMR and mass spectrometry, and by gas chromatography-mass spectrometry analysis of its 2-acetamido-4-deutero-2,6-dideoxyhexosyl derivatives produced by reduction of the 4-keto group using …
Identity Formation Of Adolescents Involved In Selected Structured Activities, Sara A. Drake
Identity Formation Of Adolescents Involved In Selected Structured Activities, Sara A. Drake
Graduate Theses, Dissertations, and Problem Reports (ETD)
Identity formation is seen as the primary developmental task during adolescence according to Erikson (1968). Adolescents' involvement in structured activities such as extracurricular activity, 4-H, and volunteerism were examined to determine their associations with identity formation. Researcher James Marcia (1966) developed four statuses of identity formation: diffusion, foreclosure, moratorium, and achieved. Categorization in one of the four statuses depends upon the levels of both crisis and commitment. Adolescents who are in the identity-diffused category have had no crisis or made no commitment. Those who foreclose, have made a commitment, but have had no crisis. Moratorium is a state of exploration, …
Seasonal Movements Of Yellow-Phase American Eels ( Anguilla Rostrata) In The Shenandoah River, West Virginia, Stephen D. Hammond
Seasonal Movements Of Yellow-Phase American Eels ( Anguilla Rostrata) In The Shenandoah River, West Virginia, Stephen D. Hammond
Graduate Theses, Dissertations, and Problem Reports (ETD)
American eels undergo extensive upstream migration in Atlantic coastal river systems. Few studies, however, have focused on movements of large yellow-phase American eels near dams in upper watersheds of Atlantic coastal rivers. We examined relationships between stream flow, water temperature, and lunar phase, and movements of radio-tagged yellow-phase American eels (518--810 mm TL) near Millville hydroelectric dam in the lower Shenandoah River, West. Movements of yellow-phase American eels differed among seasons. Water temperature and stream flow were associated with upstream migration during spring. Downstream movements during fall corresponded with decreasing water temperatures and darker nights near the new moon. Localized …

Enhancing Quality And Extending Shelf Life Of Rainbow Trout (Oncorhynchus Mykiss) By Vitamin E Supplementation And Post-Harvest Antimicrobial Intervention, Nalini Kamireddy
Graduate Theses, Dissertations, and Problem Reports (ETD)
Rainbow trout were fed a control (191 mg/kg) or the control diet supplemented with 5000 mg alpha-tocopherol/kg. Fish were sampled at 2, 3, 4, 5, 7, and 9 weeks of feeding; at each week fillets were evaluated at 0, 7, and 14 d. Supplementation increased fillet alpha-tocopherol content, and TBARS value were not affected. A feeding by storage time interaction was observed for fat content, psychrotrophic counts, cook yield, and shear force. For antimicrobial intervention, fillets were not treated or were dipped in water, 50 ppm ASC, and 1000 ppm ASC for 30 s. Fillets were stored at 1--2°C for …
Winter Habitat Use Of Fishes In The Ohio River, Benjamin Ernst Lenz
Winter Habitat Use Of Fishes In The Ohio River, Benjamin Ernst Lenz
Graduate Theses, Dissertations, and Problem Reports (ETD)
Winter is a critical period during which fishes may suffer increased mortality. To identify the habitats that fishes use in large rivers during winter conditions, we electrofished six habitat types in the Belleville Pool, Ohio River. We collected the greatest diversity and numbers of fishes in low-velocity tributary confluences when water temperatures were >4°C. When water temperatures were <4°C, certain species were collected in greater abundance in faster-velocity main channel and back channel habitats while other species continued to associate with lower flows in tributary mouths. Differing habitat use between species obscures broad generalizations about when and how fishes use overwintering refuges. In an additional habitat sampled, an embayment, 85% of all fishes collected were juveniles. Centrarchids, rarely collected in the mainstem portion of the river, were one of the dominant fishes collected in the embayment. Protecting large river embayments may prove important for managing recreational sunfish fisheries.
Brook Trout (Salvelinus Fontinalis) Movement And Habitat Use In A Headwater Stream Of The Central Appalachian Mountains Of West Virginia, Marisa Nel Logan
Brook Trout (Salvelinus Fontinalis) Movement And Habitat Use In A Headwater Stream Of The Central Appalachian Mountains Of West Virginia, Marisa Nel Logan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Brook trout (Salvelinus fontinalis) are the only salmonid native to the Appalachians. They are a resilient species, populating small, low productive streams. Although such streams have historically been abundant in the Appalachians, brook trout populations have been threatened due to habitat degradation such as logging and acidification of waters. The objective of this study was to evaluate brook trout habitat use, home range, and movement patterns in an Appalachian headwater stream during spring and more specifically high flow events. I implanted brook trout with radio tags and tracked their movement for approximately 30 days during late spring 2002 and early …

Aquaculture-Related Stress On Rainbow Trout (Oncorhynchus Mykiss) And Arctic Char (Salvelinus Alpinus), Christopher D. Nelson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Recent expansions in aquaculture characterize it as one of the fastest growing segments of the U.S. agricultural sector. Expansion has been facilitated by increased production of many important aquatic species including catfish, salmon, trout, tilapia, shrimp, oysters, and crawfish. West Virginia aquaculture, also an expanding industry, is currently characterized by small-scale, widely dispersed farms. To facilitate future expansion of aquaculture in West Virginia, focuses on product quality as well as production efficiency, identification of limiting factors and investigation into new or alternative management techniques are needed. Objectives of this project were to determine the effects of nitrite and carbon dioxide …

Soil Characterization, Classification, And Biomass Accumulation In The Otter Creek Wilderness, Jamie Schnably
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study evaluated soils of the Otter Creek Wilderness in the Monongahela National Forest. Thirteen sites were sampled and analyzed according to landscape position: three terrace soils (T), four ridgetop soils (R), three sideslope soils with argillic horizons (SSA), and three sideslope soils with cambic horizons (SSC). At each site, one pedon was described and sampled, and biomass data were collected. Standard chemical and physical properties, clay mineralogy, extractable sulfate and sulfated adsorption capacity were analyzed. The SSA soils had the highest pH, the most diverse vegetation, and the highest base saturation. These soils had a low risk for acid …
Cerulean Warbler Relative Abundance And Frequency Of Occurrence Relative To Large-Scale Edge, Scott B. Bosworth
Cerulean Warbler Relative Abundance And Frequency Of Occurrence Relative To Large-Scale Edge, Scott B. Bosworth
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cerulean Warblers (Dendroica cerulea) were studied in southwestern West Virginia where the coal mining technique of mountaintop mining/valley fill (MTMVF) continues to perforate large contiguous tracts of deciduous forest. My study objectives were to (1) quantify abundance and probability of occurrence of Cerulean Warblers relative to distance from large-scale edge (defined as reclaimed MTMVF sites) and (2) relate habitat structure and landscape characteristics to the species' probability of occurrence. Cerulean Warbler abundance increased significantly (P < 0.10) with distance from reclaimed mine edge. However, percent occurrence relative to distance from mine edge was not significant, suggesting a degree of tolerance to the large-scale edge created by MTMVF. Abundance was significantly greater on ridges than bottomlands. Percent occurrence did not differ among the three slope positions but followed a trend similar to abundance. Consequently, disturbances such as MTMVF in which ridges are removed may have a greater impact on populations compared to other sources of fragmentation where ridges are not disturbed. Other habitat structure analyses suggest good indicators of Cerulean Warbler presence are the more productive sites on northwest to east facing slopes and low sapling density. Similarly, Cerulean Warbler abundance was positively associated with more productive sites and snag density. Important landscape characteristics positively associated with abundance were large blocks of mature deciduous forest and low edge density. Mountaintop mining/valley fill alters the spatial configuration of forested habitats in southwestern West Virginia, thus creating less suitable habitat and edge effects that negatively affect Cerulean Warbler abundance, occurrence, and distribution in the reclaimed mine landscape.
Population Level Dynamics Of Grasshopper Sparrow Populations Breeding On Reclaimed Mountaintop Mines In West Virginia, Frank K. Ammer
Population Level Dynamics Of Grasshopper Sparrow Populations Breeding On Reclaimed Mountaintop Mines In West Virginia, Frank K. Ammer
Graduate Theses, Dissertations, and Problem Reports (ETD)
During 2001 and 2002, I surveyed three mountaintop mining/valley fill (MTMVF) complexes in southern West Virginia to determine vegetation characteristics important to nest site selection and to estimate nest success for Grasshopper Sparrow populations inhabiting these complexes. I also performed genetic analyses to assess overall population structure, mating system, parentage, kinship, and gender of individuals comprising these populations. A total of 415 grasshopper sparrows were captured and systematic searches of study plots produced 75 active nests. Nest survival for 2001--2002 breeding season (33%) is comparable to survival rates previously reported in the literature. Nest survival rates decreased with increased reclamation …
