Investigating climate feedbacks across forcing magnitudes and time scales using the radiative kernel technique

Creator:: Jonko, Alexandra
Abstract:: Radiative feedbacks associated with changes in water vapor, temperature, surface albedo and clouds remain a major source of uncertainty in our understanding of climate's response to anthropogenic forcing. In this dissertation climate model data is used to investigate variations in feedbacks that result from changing CO₂ forcing and the time...

Cover crop effects on root rot of sweet corn and soil properties

Creator:: Miyazoe, Mikio
Abstract:: Root rot of sweet corn in western Oregon and Washington is a significant disease that can reduce yield of intolerant cultivars of processed sweet corn by fifty percent. Root rot is caused by a complex of soilborne organisms, including Drechslera sp., Phoma terrestris, and Pythium arrhenomanes. Processors have adopted tolerant...

Winter Squash: Production and Storage of a Late Winter Local Food

Creator:: Wetzel, Jennifer D.
Abstract:: Winter squash is an important late winter vegetable crop for local and regional markets; however, farmers in western Oregon report that this crop is marginally profitable due to losses in storage and relatively low yields for the high culinary value kabocha and buttercup types. In order to increase the sales...

Soil organic matter management and root health

Creator:: Darby, Heather
Abstract:: Annual applications of fresh or composted dairy manure were assessed for their effects on root rots of sweet corn and snap bean and damping-off of cucumber in a field soil. Soil biological and physical properties were measured as possible indicators of root rot suppressive potential. Regardless of amendment type or...

Serial manure amendments : effects on soil properties and root rot of sweet corn

Creator:: Cox, Bonnie S. Hoffman
Abstract:: The effect of serial (multiple-year) organic matter (OM) amendment on soil properties has been described in some cropping systems, although less is known about the effect of serially amended field soils on soil-borne plant diseases. The objectives of this study were to describe the effects of the third and fourth...

Estimating the dry matter production, nitrogen requirements, and yield of organic farm-grown potatoes

Creator:: McQueen, John Paul Gainer
Abstract:: As part of a participatory research project, where farmers and Oregon State University researchers collaborated, aspects of potato (Solanum tuberosum L.) growing systems were studied. It was determined through conversations with the farmers that quantification of certain growth parameters of potato was lacking, including dry matter accumulation, crop nitrogen (N)...

Biosynthesis, production and structural studies of secondary metabolites in cultured marine cyanobacteria

Creator:: Vulpanovici, Florina Alexandra
Abstract:: This thesis details investigations of marine cyanobacterial secondary metabolism, with emphasis on a strain of Phormidium sp. collected in Indonesia. These studies assessed the effects of nineteen putative elicitor compounds on the growth and metabolite production of five species of marine cyanobacteria, biosynthetic investigation of an intriguing secondary metabolite, phormidolide,...

How Nearshore Currents affect Larval Dispersal and Genetic Connectivity of China Rockfish (Sebastes nebulosus) Along Oregon and Washington Coasts

Creator:: Avila, Alexandra M.
Abstract:: Connectivity of fish populations is a crucial question for fisheries conservation and the development of spatial management plans. Both adult and larval movement define the extent and direction of ecological and evolutionary overlap between geographic regions and, therefore, how we define stocks for management purposes. Within that context, my work...

Patterns of carbon storage within a mature northern highbush blueberry production system

Creator:: Nemeth, Denise Alexandra
Abstract:: The objectives of this study were to: 1) determine how organic matter (incorporated vs. surface mulch) and nitrogen fertilization rate impact northern highbush blueberry (Vaccinium corymbosum L.) plant biomass, carbon accumulation, plant losses and allocation, and mycorrhizal infection in mature plants, and 2) determine the magnitude of carbon fluxes (carbon...

Risk Perceptions and Behavioral Intentions : Responses to the Threat of Cascadia Subduction Zone Earthquakes and Tsunamis.

Creator:: Buylova, Alexandra
Abstract:: This research examined public perceptions of risk, behavioral intentions in the event of the M9 Cascadia Subduction Zone (CSZ) earthquake and tsunami on the Oregon Coast, and factors that may influence both attitudes and intentions. A household survey was conducted to understand public opinion in Seaside, Oregon, which is located...
