Comparative study of the population dynamics, secondary productivity, and reproductive ecology of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Oregon upwelling region

Creator:: Gutierrez, Jaime Gomez
Abstract:: I compare the seasonal abundance variation, population dynamics, fecundity, egg hatching mechanism and success, and apostome ciliate parasites of the euphausiids Euphausia pac?fica and Thysanoessa spinfera from the Oregon coast, USA. Community structure and nearshore distributions were examined from bi-weekly oceanographic surveys (1970-1972). This region has a strong cross-shelf change...

Impact of tropical instability waves on nutrient and chlorophyll distributions in the equatorial Pacific

Creator:: Evans, William Wiley
Abstract:: Tropical instability waves (TIWs) are prominent seasonal features in both the equatorial Pacific and Atlantic Oceans. This work quantifies their role in modulating the distributions of nutrients and phytoplankton biomass. Using an eight year record of biannual ship observations along the Tropical Atmosphere Ocean (TAO) buoy array, cruise sections crossing...

Sea-air CO₂ flux variability on the northeast Pacific continental margin

Creator:: Evans, Wiley
Abstract:: Carbon dioxide (CO₂) fluxes between the ocean and atmosphere on continental margins are difficult to diagnose because these regions experience large variability over spatial and temporal scales spanning meters to basins and hours to years, respectively. In a global sense, continental margins could represent a significant atmospheric CO₂ sink, equivalent...

Ecological subsidies to rocky shore communities : setting the stage for community dynamics in the Northeast Pacific

Creator:: Krenz, Christopher
Abstract:: This dissertation focuses on the importance of pelagic subsidies in the Northeast Pacific to rocky shore community regulation. My results document the patterns of pelagic subsidy supply, determine if those subsidies are correlated with community structure, and examine if community regulation differs between areas of high- and low-subsidies. Understanding how...

Structure-function analysis of the vaccinia virus I7L proteinase

Creator:: Moerdyk, Megan J.
Abstract:: Vaccinia virus is the prototypic member of the Orthopoxvirus genus. It undergoes a complex replication process where a key step in the transition from immature virion to intracellular mature virion is the cleavage of the major core protein precursors. The product of the I7L open reading frame (ORF) is a...

The spectral backscattering properties of marine particles

Creator:: Whitmire, Amanda L.
Abstract:: The inherent and apparent optical properties of different ocean regimes are the basis for all optical remote sensing of the ocean. Ecological information derived from remote sensors therefore relies on having a detailed understanding of how particulate backscattering and absorption contribute to the bulk optical signal. The absorption characteristics of...

Seconds to hour scale photosynthetic responses in marine microalgae

Creator:: Laney, Samuel R.
Abstract:: Our view of phytoplankton has historically revolved around their inability to control their location in space. The term phytoplankton itself underscores this particular difference between phytoplankton and their sessile terrestrial counterparts. Yet there are other differences between land plants and the phytoplankton that are perhaps equally important, beyond this sessile-planktonic...

Composition of Pinot noir Wines Produced from Different Crop Levels

Creator:: Li, Jingwen
Abstract:: The production of high-quality wine is an important target for wineries worldwide, and low crop level (yield) has been one vineyard management criterion long believed to achieve wine quality. Low yields are most often achieved by removing clusters from the grapevine. Some studies show that cluster thinning can enhance grape...

Development of volatile composition and C₁₃-norisoprenoid precursors in Pinot noir grape, Development of volatile composition and C13-norisoprenoid precursors in Pinot noir grape

Creator:: Yuan, Fang
Abstract:: This study first investigated the developmental changes in the volatile composition and carotenoids of Pinot noir grapes. Grape berries were sampled every week from pea size to harvest during the 2011 and 2012 season. Carotenoids and organic acids were analyzed by HPLC. Volatile compounds were extracted from crushed berries using...

Efficacy of Cultural Practices for Mitigating the Negative Impacts of Grapevine Red Blotch Virus on Vine Physiology and Fruit Composition in Oregon Pinot Noir

Creator:: Copp, Cody R.
Abstract:: The recently emerged Grapevine Red Botch Virus (GRBV) impedes proper berry ripening primarily by reducing sugar accumulation and color development in red-fruited Vitis vinifera L. cultivars. To date, there is no recommended management strategy for virus spread or the impacts of the disease beyond removal and replacement of infected vines....
