This study investigated how manipulating vineyard nitrogen status, irrigation levels and cultivation practices would effect nutrient composition, and anthocyanin and phenolic accumulation in Pinot noir juice and wine from a commercial Willamette Valley Oregon vineyard. Pinot noir fruit was sourced from a vineyard trial in the Benton Lane Vineyard, located...
The rapid increase in atmospheric carbon dioxide (CO₂) over the last 250 years has led to the absorption of approximately 550 billion tons of anthropogenic CO₂ by the global ocean. This oceanic uptake of CO₂ has resulted in decreasing pH and alterations to carbonate chemistry, threatening many ecologically and economically...
Recent studies of estuarine sediment deposits have focused on grain size spectra as a tool to better understand depositional processes, in particular those associated with tidal inlet and basin dynamics. The key to accurate interpretation of lithostratigraphic sequences is establishing clear connections between morphodynamic changes and the resulting shifts in...
Larvae of the Pacific Oyster, Crassostrea gigas, at Whiskey Creek Shellfish Hatchery (WCH) in Netarts Bay, Oregon, are negatively impacted by high-CO₂ water and exposure during the initial shell formation period appears to be particularly damaging. To investigate the mechanism of this early susceptibility, several cohorts of larvae at WCH...
Ocean acidification (OA) is the result of increasing concentrations of anthropogenic carbon dioxide (CO₂) emissions, leading to a suite of alterations to specific parameters of ocean chemistry, which can negatively impact many marine organisms and ecosystems. Understanding how to measure and monitor the chemistry of OA will require specialized education...
A novel, low-cost instrument capable of measuring surface water PCO₂ was designed for use in dynamic, shallow-water environments. The instrument was tested in the Yaquina River Estuary, a macrotidal estuary known to experience a wide range of conditions ranging from dominance by the coastal ocean during summer upwelling to substantial...
Experimental evolution is a tool that allows us to measure changes in populations over time in controlled, novel environments. Microbial evolution experiments use cryopreservation – storage at -80°C in glycerol media – to archive experimental populations. Research with Escherichia coli suggests that cryopreservation conditions can affect cell viability and that...
In the field of natural resource policy and management, community-based collaboration is a strategy that has been growing in scope and usage over the past three decades, and often offers hope in complex, difficult conflict situations. In Oregon's Illinois Valley, where conflicts over natural resource management have been ongoing for...
This dissertation presents the Graham Model of Bibliosupervision (GMB). The purpose
of this study is to examine the efficacy of the GMB and its influence on the supervisory
working alliance. Specifically this study examines the effectiveness of a non-linear
approach to counselor supervision that employs children’s literature as part of...
