D-Lactate metabolism and the obligate requirement for CO2 during growth on nitrite by the facultative lithoautotroph Nitrobacter hamburgensis

Creator:: Starkenburg, Shawn R., Arp, Daniel J., and Bottomley, Peter J.
Abstract:: Nitrobacter hamburgensis X14 is a facultative lithoautotroph that conserves energy from the oxidation of nitrite (NO 2 ) and fixes carbon dioxide (CO2) as its sole source of carbon. The availability of the N. hamburgensis X14 genome sequence initiated a re-examination of its mixotrophic and organotrophic potential, as genes encoding...

Stand Structures of Oregon White Oak Woodlands, Regeneration, and Their Relationships to the Environment in Southwestern Oregon

Creator:: Gilligan, Laurie A. and Muir, Patricia S.
Abstract:: Although Oregon white oak (Quercus garryana) woodlands are a characteristic landscape component in southwestern Oregon, little is known about their current or historical stand structures. Meanwhile, fuel reduction thinning treatments that change stand structures in non-coniferous communities are ongoing and widespread on public lands in this region; some of these...

Geographic, climatic, and chemical differentiation in the Hypogymnia imshaugii species complex (Lecanoromycetes, Parmeliaceae) in North America

Creator:: McCune, Bruce, Schoch, Conrad, Root, Heather T., Kageyama, Stacie A., and Miadlikowska, Jolanta
Abstract:: Hypogymnia imshaugii is one of the most common, conspicuous and morphologically variable epiphytic lichens of the Pacific coastal states and provinces. The species varies greatly in morphology and chemistry, suggesting multiple closely related species or one or more phenotypically plastic species. We sought to determine whether additional ecologically meaningful species...

Orbilia ultrastructure, character evolution and phylogeny of Pezizomycotina

Creator:: Kumar, T.K. Arun, Healy, Rosanne, Spatafora, Joseph W., Blackwell, Meredith, and McLaughlin, David J.
Abstract:: Molecular phylogenctic analyses indicate that the monophyletic classes Orbiliomycetes and Pezizomycetes are among the earliest diverging branches of Pezizomycotina, the largest subphylum of the Ascomycota. Although Orbiliomycetes is resolved as the most basal lineage in some analyses, molecular support for the node resolving the relationships between the two classes is...

Developing Models for the Forage Ratios of Culiseta melanura and Culex erraticus using Species Characteristics for Avian Hosts

Creator:: Estep, Laura K., McClure, Christopher J. W., Burkett-Cadena, Nathan D., Hassan, Hassan K., Unnasch, Thomas R., and Hill, Geoffrey E.
Abstract:: Studies of mosquito preferences for avian hosts have found that some bird species are at greater risk than others of being fed upon by mosquitoes. The ecological factors that determine this interspecific variation in avian host use by mosquitoes have been little studied, despite the possibility that such variation may...

Pararaucaria carrii sp nov., anatomically preserved evidence for the conifer family cheirolepidiaceae in the northern hemisphere

Creator:: Stockey, Ruth A. and Rothwell, Gar W.
Abstract:: A cylindrical permineralized conifer seed cone has been identified from the Officer Member of the Trowbridge Formation, near Izee, in east-central Oregon. The cone is preserved in a Middle Jurassic (Callovian) marine calcium carbonate concretion, associated with araucarian seed cones, conifer twigs and wood, cycad seeds, fern rachides, and lycopodialean...

Wind farm potential is higher in prime habitat for uncommon soil crust lichens

Creator:: Root, Heather T., McCune, Myrica, and McCune, Bruce
Abstract:: Introduction: Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi are associated with fine-textured soils along rivers of the Columbia Basin. A. schleicheri and R. diploschistidina indicate late-successional habitat and may serve as...

Evolving while invading: rapid adaptive evolution in juvenile development time for a biological control organism colonizing a high-elevation environment

Creator:: McEvoy, Peter B., Higgs, Kimberley M., Coombs, Eric M., Karacetin, Evrim, and Starcevich, Leigh Ann
Abstract:: We report evidence of adaptive evolution in juvenile development time on a decadal timescale for the cinnabar moth Tyria jacobaeae (Lepidoptera: Arctiidae) colonizing new habitats and hosts from the Willamette Valley to the Coast Range and Cascades Mountains in Oregon. Four lines of evidence reveal shorter egg to pupa juvenile...

The Seed Cone Eathiestrobus gen. nov.: Fossil Evidence for a Jurassic Origin of Pinaceae

Creator:: Rothwell, Gar W., Mapes, Gene, Stockey, Ruth A., and Hilton, Jason
Abstract:: Premise of the study: Pinaceae and nonpinoid species are sister groups within the conifer clade as inferred from molecular systematic comparisons of living species and therefore should have comparable geological ages. However, the fossil record for the nonpinoid lineage of extant conifer families is Triassic, nearly 100 million years older...

Kinetic and Spectroscopic Analysis of the Inactivating Effects of Nitric Oxide on the Individual Components of Azotobacter vinelandii Nitrogenase

Creator:: Hyman, Michael R., Seefeldt, Lance C., Morgan, Vance, Arp, Daniel J., and Mortenson, Leonard E.
Abstract:: The effects of nitric oxide (NO) on the individual components of Azotobacter vinelandii nitrogenase have been examined by kinetic and spectroscopic methods. Incubation of the Fe protein (Av2) for 1 h with stoichiometries of 4- and 8-fold molar excesses of NO to Av2 dimer resulted in a complete loss of...
