Phytophthora species and riparian alder tree damage in western Oregon

Creator:: Sims, Laura L.
Abstract:: The genus Phytophthora contains some of the most destructive pathogens of forest trees, including the most destructive pathogen of alder in recent times, Phytophthora alni. Alder trees were reported to be suffering from canopy dieback in riparian ecosystems in western Oregon, which prompted a survey of alder health and monitoring...

The Phytophthora species assemblage and diversity in riparian alder ecosystems of western Oregon, USA

Creator:: Sims, Laura Lee, Sutton, Wendy, Reeser, Paul, and Hansen, Everett M.
Abstract:: Phytophthora species were systematically sampled, isolated, identified and compared for presence in streams, soil and roots of alder (Alnus species) dominated riparian ecosystems in western Oregon. We describe the species assemblage and evaluate Phytophthora diversity associated with alder. We recovered 1250 isolates of 20 Phytophthora species. Only three species were...

Alder Canopy Dieback and Damage in Western Oregon Riparian Ecosystems

Creator:: Sims, Laura, Goheen, Ellen, Kanaskie, Alan, and Hansen, Everett
Abstract:: We gathered baseline data to assess alder tree damage in western Oregon riparian ecosystems. We sought to determine if Phytophthora-type cankers found in Europe or the pathogen Phytophthora alni subsp. alni, which represent a major threat to alder forests in the Pacific Northwest, were present in the study area. Damage...

Profiling Zebrafish Developmental Responses to E-Cigarette Flavor Mixtures

Creator:: Holden, Laura, L.
Abstract:: Since 2007, electronic cigarette (e-cigarette) sales in the U.S. have surpassed those of tobacco cigarettes. This is due, in part, to manufacturer’s claims that they are a safer alternative to tobacco cigarettes. However, formaldehyde, acrolein, and diacetyl have been detected in e-cigarettes and public knowledge of e-cigarette composition and potential...

Person-environment fit and adaptation : exploring the interaction between person and environment in older age

Creator:: Lien, Laura L.
Abstract:: The ability to independently age in place requires an appropriate match between a person and the environment, or P-E fit. The person-environment interaction helps describe the adaptation processes employed in older age to achieve P-E fit, but is little understood. Therefore, the objective of this two-part study was to gain...

Use of tethered prey for estimating the impact of the invasive European green crab

Creator:: Hauck, Laura L.
Abstract:: Various mollusks, including small bivalves and gastropod snails, are a common food source for intertidal crabs. Prey opening techniques used on hard-shell prey are dependent on claw size and morphology. For example, large, strong claws can crush a snail outright while smaller, weaker claws leave characteristic peels, pulls and upper...

Molecular genetics and enzymology of secondary metabolite biosynthesis. I, Isolation of natural product biosynthesis gene clusters from symbiotic marine organisms. II, Enzymology of blasticidin S biosynthesis

Creator:: Grochowski, Laura L.
Abstract:: Molecular genetic and enzymological techniques have been employed to study secondary metabolite biosynthesis. These investigations have focused on two projects: the cloning and heterologous expression of biosynthetic gene clusters from unculturable marine organisms and the characterization of individual enzymes involved in the biosynthesis of the antifungal agent blasticidin S. The...

Sunbeam: A Fairy Tale

Creator:: Cummings, Laura L.
Abstract:: The heroine of this fantasy novel is Alina who lives in a medieval-like time and place. The day before her 20th birthday, in an impetuous moment, she breaks a local superstition by standing in a sunbeam. This allows a fairy to kidnap her and take her to the fairy castle...

Molecular investigation of the cnidarian-dinoflagellate symbiosis and the identification of genes differentially expressed during bleaching in the coral Montipora capitata

Creator:: Hauck, Laura L.
Abstract:: Cnidarians, such as anemones and corals, engage in an intracellular symbiosis with photosynthetic dinoflagellates. Corals form both the trophic and structural foundation of reef ecosystems. Despite their environmental importance, little is known about the molecular basis of this symbiosis. In this dissertation we explored the cnidariandinoflagellate symbiosis from two perspectives:...

Ensemble Generation for Models of Multimodal Systems

Creator:: Miller, Robert N. and Ehret, Laura L.
Abstract:: In this work the performance of ensembles generated by commonly used methods in a nonlinear system with multiple attractors is examined. The model used here is a spectral truncation of a barotropic quasigeostrophic channel model. The system studied here has 44 state variables, great enough to exhibit the problems associated...

Adaptive Strategies and Person-Environment Fit among Functionally Limited Older Adults Aging in Place: A Mixed Methods Approach

Creator:: Lien, Laura L., Steggell, Carmen D., and Iwarsson, Susanne
Abstract:: Older adults prefer to age in place, necessitating a match between person and environment, or person-environment (P-E) fit. In occupational therapy practice, home modifications can support independence, but more knowledge is needed to optimize interventions targeting the housing situation of older adults. In response, this study aimed to explore the...

Abstract:: The production of high quality grass seed is important to the agricultural economy of the Grande Ronde Valley (GRV) of eastern Oregon. The predominate grass seed crops grown in the area are Kentucky bluegrass and fine fescues. Historically, open-field burning has been an effective, economical means by which to remove...

Abstract:: Ebola virus causes an acute hemorrhagic fever lethal in primates and rodents. The contribution of host immune factors to pathogenesis has yet to be determined and may reveal efficacious targets for potential treatment. In this study, we show that the interleukin (IL)-10 signaling pathway modulates Ebola pathogenesis. IL-10 [superscript -...

Utility of a Work Process Classification System for characterizing non-fatal injuries in the Alaskan commercial fishing industry

Creator:: Syron, Laura N., Lucas, Devin L., Bovbjerg, Viktor E., Bethel, Jeffrey W., and Kincl, Laurel D.
Abstract:: Background. The US commercial fishing industry is hazardous, as measured by mortality data. However, research on non-fatal injuries is limited. Non-fatal injuries constitute the majority of occupational injuries and can result in workers' lowered productivity and wages, lost quality of life, and disability. In the United States, a Work Process...
