Near collapse of the meridional SST gradient in the eastern equatorial Pacific during Heinrich Stadial 1

Creator:: Kienast, Stephanie S., Friedrich, Tobias, Dubois, Nathalie, Hill, Paul S., Timmermann, Axel, Mix, Alan C., and Kienast, Markus
Abstract:: Sea surface temperatures (SST) and inorganic continental input over the last 25,000 years (25 ka) are reconstructed in the far eastern equatorial Pacific (EEP) based on three cores stretching from the equatorial front (~0.01°N, ME0005-24JC) into the cold tongue region (~3.6°S; TR163-31P and V19-30). We revisit previously published alkenone-derived SST...

A review of nitrogen isotopic alteration in marine sediments

Creator:: Robinson, Rebecca S., Kienast, Markus, Albuquerque, Ana Luiza, Altabet, Mark, Contreras, Sergio, De Pol Holz, Ricardo, Dubois, Nathalie, Francois, Roger, Galbraith, Eric, Hsu, Ting-Chang, Ivanochko, Tara, Jaccard, Samuel, Kao, Shuh-Ji, Kiefer, Thorsten, Kienast, Stephanie, Lehmann, Moritz, Martinez, Philippe, McCarthy, Matthew, Mobius, Jurgen, Pedersen, Tom, Quan, Tracy M., Ryabenko, Evgeniya, Schmittner, Andreas, Schneider, Ralph, Schneider-Mor, Aya, Shigemitsu, Masahito, Sinclair, Dan, Somes, Christopher, Studer, Anja, Thunell, Robert, and Yang, Jin-Yu
Abstract:: Nitrogen isotopes are an important tool for evaluating past biogeochemical cycling from the paleoceanographic record. However, bulk sedimentary nitrogen isotope ratios, which can be determined routinely and at minimal cost, may be altered during burial and early sedimentary diagenesis, particularly outside of continental margin settings. The causes and detailed mechanisms...

Modeling and Finite Element Analysis of a Standard Concrete Canoe

Creator:: Stache, Stephanie S.
Abstract:: This thesis project provides a guiding framework for the structural analysis portion of the National Concrete Canoe Competition (NCCC). Step-by-step instructions on how to 3-dimensionally model a “standard” sized concrete canoe in AutoCAD Civil 3D, import the model into SAP2000, and proceed to analyze the canoe with the SAP2000 finite...

All hosts are not created equal : variation in amphibian responses to an emerging fungal pathogen and why it matters

Creator:: Gervasi, Stephanie S.
Abstract:: Emerging infectious diseases are increasing globally and are a threat to human, wildlife, and ecosystem health. The emerging fungal pathogen, Batrachochytrium dendrobatidis (Bd), or amphibian chytrid fungus, is associated with worldwide amphibian population declines and extinctions. Bd has been found on every continent where amphibians exist and has been documented...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K., Hibbs, David E., and Perakis, Steven S.
Abstract:: Riparian-zone vegetation can influence terrestrial and aquatic food webs through variation in the amount, timing, and nutritional content of leaf and other litter inputs. We investigated how riparianforest community composition, understory density, and lateral slope shaped vertical and lateral litter inputs to 16 streams in the Oregon Coast Range. Riparian...

Prevalence of Exertional Rhabdomyolysis in Endurance Horses in the Pacific Northwestern United States

Creator:: Wilberger, Melissa S., Mckenzie, Erica C., Payton, Mark E., Rigas, Johanna. D., and Valberg, Stephanie J.
Abstract:: SUMMARY - REASONS FOR PERFORMING STUDY: Exertional rhabdomyolysis (ER) is a reported syndrome in competing endurance horses; however the prevalence and cause of ER in this population has not been defined. OBJECTIVES: To determine the prevalence of ER in a sample of endurance racing horses, and to investigate factors, including...

Viral Outbreak in Corals Associated with an In Situ Bleaching Event: Atypical Herpes-Like Viruses and a New Megavirus Infecting Symbiodinium

Creator:: Correa, Adrienne M. S., Ainsworth, Tracy D., Rosales, Stephanie M., Thurber, Andrew R., Butler, Christopher R., and Thurber, Rebecca L. Vega
Abstract:: Previous studies of coral viruses have employed either microscopy or metagenomics, but few have attempted to comprehensively link the presence of a virus-like particle (VLP) to a genomic sequence. We conducted transmission electron microscopy imaging and virome analysis in tandem to characterize the most conspicuous viral types found within the...

Differences in sensitivity to the fungal pathogen Batrachochytrium dendrobatidis among amphibian populations

Creator:: Bradley, Paul W., Gervasi, Stephanie S., Hua, Jessica, Cothran, Rickey, D., Relyea, Rick A., Olson, Deanna H., and Blaustein, Andrew R.
Abstract:: Contributing to the worldwide biodiversity crisis are emerging infectious diseases, which can lead to extirpations and extinctions of hosts. For example, the infectious fungal pathogen Batrachochytrium dendrobatidis (Bd) is associated with worldwide amphibian population declines and extinctions. Sensitivity to Bd varies with species, season, and life stage. However, there is...

Assessment of the Introductory Transportation Engineering Course and the General Transportation Engineering Curriculum

Creator:: Turochy, Rod E., Fricker, Jon, Hawkins, H. Gene, Jr., Hurwitz, David S., Ivey, Stephanie S., Knodler, Michael A., Jr., and Young, Rhonda Kae
Abstract:: Transportation engineering is a critical subdiscipline of the civil engineering profession as indicated by its inclusion on the Fundamentals of Engineering Examination, its overlap with other specialty areas of civil engineering, and as recognized by the Transportation Research Board, Institute of Transportation Engineers, and the American Society of Civil Engineers....

Genome-Wide Scan and Test of Candidate Genes in the Snail Biomphalaria glabrata Reveal New Locus Influencing Resistance to Schistosoma mansoni

Creator:: Tennessen, Jacob A., Bonner, Kaitlin M., Bollmann, Stephanie R., Johnstun, Joel A., Yeh, Jan-Ying, Marine, Melanie, Tavalire, Hannah F., Bayne, Christopher J., and Blouin, Michael S.
Abstract:: Background: New strategies to combat the global scourge of schistosomiasis may be revealed by increased understanding of the mechanisms by which the obligate snail host can resist the schistosome parasite. However, few molecular markers linked to resistance have been identified and characterized in snails. Methodology/Principal Findings: Here we test six...
