A G-type Lectin Receptor-like Kinase Associated with Septoria Canker Resistance and Susceptibility Described using Multi-omics and Biotechnology

Creator:: Lenz, Ryan R.
Abstract:: Managers of forest and plantation ecosystems are encountering growing problems involving plant pathogens and the expanding geographic ranges of these pathogens. Historically unexposed stands are exceptionally vulnerable when a non-native pathogen is introduced because these pathogens can cause devastating disease in a host population that lacks co-evolved resistance mechanisms. One...

Community Ecology of Foliar Fungi and Oomycetes of Pseudotsuga menziesii on the Pacific Northwest Coast

Creator:: Gonen, Lilah
Abstract:: Pseudotsuga menziesii var. menziesii (coast Douglas-fir) is a tree of ecological, economic, and cultural value in its native North American Pacific Northwest (PNW) distribution. P. menziesii is host to a variety of well-documented endophytic foliar microorganisms, including the fungus Nothophaeocryptopus gaeumannii, the causal agent of Swiss needle cast (SNC), and...

Identification and Occurrence of Sweet Cherry (Prunus avium) Virus and Virus-Like Diseases in Various Regions and Orchards of Oregon

Creator:: Reinhold, Lauri A.
Abstract:: There are over 35 known virus and virus-like diseases of sweet cherry (Prunus avium), some with potential to cause severe economic impact by reducing vegetative growth, vigor, and/or quality of fruit. Oregon is the second-ranked state for sweet cherry production in the United States with 13,000 acres and $70.8 million...

Diagnosis and Etiology of a Soilborne Disease Complex of Winter Squash (Cucurbita maxima) in the Willamette Valley, OR

Creator:: Rivedal, Hannah M.
Abstract:: Winter squash (Cucurbita maxima) grown in Oregon’s Willamette Valley for edible seed, frozen foods, and fresh markets is susceptible to an undiagnosed soilborne disease. Diseased squash fields exhibit symptoms of stunting, root and crown rot, vascular discoloration, and late-season wilt, which in extreme cases can lead to total crop failure....

Optimizing shared mooring and anchoring strength for floating offshore wind turbine arrays

Creator:: Devin, Michael C.
Abstract:: Energy from offshore wind could provide substantial power generation if further utilized. One area of significant research focus is in developing floating offshore wind devices, which would allow for wind energy to be gathered in deep water where driven monopile turbines are infeasible. However, floating offshore wind is not currently...

Tree Physiological, Physical, and Chemical Characteristics Related to Spruce Beetle Colonization: Engelmann versus Blue Spruce

Creator:: Ott, Daniel S.
Abstract:: Blue spruce (Picea pungens) and Engelmann spruce (Picea engelmannii) experience varying levels of spruce beetle (Dendroctonus rufipennis (Kirby)) colonization, yet the underlying differences and mechanisms resulting in lower colonization for blue spruce are not known. Both spruce species have important roles in subalpine ecosystems where examining changes in mortality, distribution,...

Soil Solarization in Pacific Northwest Tree Seedling Nurseries: Effects on Soilborne Plant Pathogens, Soil Nutrients and the Soil Microbiome

Creator:: Weidman, Clara S.
Abstract:: Nursery and greenhouse products are economically important agricultural commodities for Oregon and Washington. Nursery crops including tree seedlings can be damaged or killed by soilborne plant pathogens, which can be challenging to manage because of their persistence in soil and limited options for control. Soil solarization is a pre-planting soil...

Addressing Seedling Production Challenges for Hispaniolan Pine and Snowberry

Creator:: St. John, Christina M.
Abstract:: The use of native plants in restoration and afforestation has increased worldwide as their benefits to habitat quality, ecosystem services and local community well-being become widely known. In many restoration and afforestation sites, the most cost-effective and efficient way to establish plants is to use seedlings. Unfortunately, there is a...

Understanding Community Opposition to Industrial Scale Wind Farm Sitings and the Impacts of Federal Fast Track Initiatives in Southern California: A Case Study of the Tule and Ocotillo Wind Energy Facilities

Creator:: Allouzi, Yousef
Abstract:: As climate change forces energy policy to incorporate environmental impacts and fuel diversification into the traditional model of energy security, finding ways to site, develop, and deliver renewable energy has taken on increasing importance across the United States. With no consistent federal framework to implement these changes, much of the...

Forms of Life: Goethe’s Impact on Twentieth-Century Anglophone Botany and Morphology

Creator:: Hahn, Andre M.
Abstract:: This dissertation examines the impact of the German naturalist and literary figure Johann Wolfgang von Goethe’s ideas on twentieth century Anglophone plant morphology and biology. Goethe interpreted the organ forms of flowering plants as metamorphoses of each other. His literary, historical, and philosophical writings suggest themes of alienation from and...
