The role of keratinocytic RXRα in regulating melanocyte homeostasis and carcinogen induced melanomagenesis, The role of keratinocytic RXR[alpha] in regulating melanocyte homeostasis and carcinogen induced melanomagenesis

Creator:: Hyter, Stephen D.
Abstract:: Cutaneous melanoma remains the deadliest form of skin cancer, with a diagnosis of metastasis indicating a median survival rate of less than a year. Solar ultraviolet (UV) radiation, especially childhood sun exposure, is an important etiological risk factor of melanoma. Previous studies determined that mice selectively lacking the nuclear hormone...

Widespread distribution of Ceratonova shasta (Cnidaria: Myxosporea) genotypes indicates evolutionary adaptation to its salmonid fish hosts

Creator:: Stinson, Matthew E. T., Atkinson, Stephen D., and Bartholomew, Jerri L.
Abstract:: The distribution of the freshwater myxozoan parasite Ceratonova shasta in the Pacific Northwest of North America is limited to overlap in the ranges of its 2 hosts: the polychaete Manyunkia sp., and Pacific salmonids. Studies in the Klamath River (Oregon/California) and Deschutes River (Oregon), showed that the parasite population is...

From fossils to phylogenies

Creator:: Goodwin, Baylee N., Besser, August D., and Ramsey, Stephen A.
Abstract:: The research question address in this study is, “To what extent will the use of hands-on activities for introducing concepts in bioinformatics promote student engagement in after-school STEM club settings?” It is hypothesized that high school students' engagement in hands-on bioinformatics activities promotes their awareness of, and interest in, STEM...

Recovering lost ground: Effects of soil burn intensity on nutrients and ectomycorrhiza communities of ponderosa pine seedlings

Creator:: Cowan, Ariel D., Smith, Jane E., and Fitzgerald, Stephen A.
Abstract:: Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in pon-derosa pine (Pinus ponderosa) forests of central Oregon. The combustion of fuels containing large downedwood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previousstudies show ectomycorrhizal fungi (EMF) improve...

A case for trading risk in complex conceptual design trade studies

Creator:: Van Bossuyt, Douglas L., Tumer, Irem Y., and Wall, Stephen D.
Abstract:: Complex conceptual system design trade studies traditionally consider risk after a conceptual design has been created. Further, one person is often tasked with collecting risk information and managing it from each subsystem. This paper proposes a method to explicitly consider and trade risk on the same level as other important...

Comparative hazard assessment for protected species in a fire-prone landscape

Creator:: Roloff, Gary J., Mealey, Stephen P., and Bailey, John D.
Abstract:: We conducted a comparative hazard assessment for 325,000 ha in a fire-prone area of southwest Oregon, USA. The landscape contains a variety of land ownerships, fire regimes, and management strategies. Our comparative hazard assessment evaluated the effects of two management strategies on crown fire potential and northern spotted owl (Strix...

Tree thinning and fire affect ectomycorrhizal fungal communities and enzyme activities

Creator:: Rasmussen, Ann L., Brewer, J. Stephen, Jackson, Colin R., and Hoeksema, Jason D.
Abstract:: Common ecological restoration treatments such as thinning trees and prescribed burning could result in changes to soil fungal communities and changes to the function of those communities. Ectomycorrhizal fungi are especially likely to be affected as they are symbionts on plant roots and exhibit host and niche preferences. Ectomycorrhizal fungi...

A novel myxozoan parasite of terrestrial mammals: description of Soricimyxum minuti sp n. (Myxosporea) in pygmy shrew Sorex minutus from Hungary

Creator:: Székely, Csaba, Cech, Gábor, Atkinson, Stephen D., Molnár, Kálmán, Egyed, László, and Gubányi, András
Abstract:: As part of a biodiversity study in northwestern Hungary, we conducted a parasitological survey of small mammals. In both common shrews (Sorex araneus Linnaeus) and pygmy shrews (Sorex minutus Linnaeus), we found myxospores of a species of Soricimyxum Prunescu, Prunescu, Pucek et Lom, 2007 (Myxosporea) and plasmodia in the bile...

Biochar production and applications in sub-Saharan Africa: Opportunities, constraints, risks and uncertainties

Creator:: Gwenzi, Willis, Chaukura, Nhamo, Mukome, Fungai N. D., Machado, Stephen, and Nyamasoka, Blessing
Abstract:: Sub-Saharan Africa (SSA) experiences soil degradation, food and livelihood insecurity, environmental pollution and lack of access to energy. Biochar has gained international research attention, but few studies have investigated the potential of biochar to address the challenges in SSA. This paper seeks to identify and evaluate generic potential opportunities and...

Occurrence of demersal fishes in relation to near-bottom oxygen levels within the California Current large marine ecosystem

Creator:: Keller, Aimee A., Ciannelli, Lorenzo, Wakefield, W. Waldo, Simon, Victor, Barth, John A., and Pierce, Stephen D.
Abstract:: Various ocean-climate models driven by increased greenhouse gases and higher temperatures predict a decline in oceanic dissolved oxygen (DO) as a result of greater stratification, reduced ventilation below the thermocline, and decreased solubility at higher temperatures. Since spreading of low oxygen waters is underway and predicted to increase, understanding impacts...
