  • Physiological characterization of the mixotrophic dinoflagellate Amphidinium carterae

    Creator:
    Tornberg, Emma C.
    Abstract:
    Marine primary production can be modeled and estimated using remotely-observable physiological signatures such as chlorophyll and carbon. Current models are based on strict physiological relationships based on photoautotrophic phytoplankton, and discrepancies between modeled and in situ data may stem from unaccounted-for physiological deviations from photoautotrophy. Mixotrophic phytoplankton can obtain energy...

  • The effects of marine biodiversity loss on coastal economics

    Creator:
    McAbery, Emma
    Abstract:
    The oceans are one of humanity’s greatest resources, providing food, raw materials, livelihoods, and protection. More than 3 billion people around the world rely on marine life as a source of protein as well as their livelihood. Seafood is one of the highest traded commodities globally and many major cities...

  • Wildfire Severity Has a Minimal Influence on Pollen Diversity Used by Developing Mason Bees (Osmia lignaria) in Mixed Conifer Forest

    Creator:
    Bell, Nicole C. S.
    Abstract:
    Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...

  • Stress and Learning in Larval Zebrafish (Danio rerio)

    Creator:
    Moussaoui, Bushra
    Abstract:
    In this study, we characterize the behavioral response of larval zebrafish (Danio rerio) to the noxious chemical allyl isothiocyanate (AITC), an agonist of the nociceptive TRPA1 ion channel, and utilize AITC as an aversive stimulus in an associative learning paradigm. We find that larvae exposed to AITC in both a...

  • Phase Separation in Microscale Convective Boiling

    Creator:
    Lewis, Kevin Terrence
    Abstract:
    It is hypothesized that extracting the vapor from two-phase flow in a microchannel will result in a lowered pressure drop required to drive the flow. The goal of this thesis is to construct an experimental device that will test this hypothesis by comparing a number of phase separating test conditions...

  • Early competitive environments differentially influence stress axis responses in sympatric, ecologically similar songbirds

    Creator:
    Hardt, Braelei M.
    Abstract:
    1. Early competitive environments can shape the development of offspring across taxa. For example, competition for food can have downstream effects on offspring phenotypes and fitness; however, little is known about how early competition influences the development of the hypothalamic-pituitary axis and its potential tradeoff with growth. Because baseline and...

  • Impact of pre-fermentation maceration techniques on yeast populations and color of Pinot noir wine

    Creator:
    Zook, Molly L.
    Abstract:
    The quality of red wine is primarily determined by the flavor, aroma, and color. A common wine making technique used to improve these characteristics is the pre-­‐fermentation maceration. In this study two pre-fermentation maceration techniques were used, one was a traditional cold soak and the second involved addition of dry...

  • Old Crops in a New World: Bringing Andean Tuber Crops to the Pacific Northwest

    Creator:
    Reers, Michelle
    Abstract:
    Though currently relatively unknown outside Latin America, Andean root and tuber crops are rapidly gaining interest elsewhere. Tubers are a major food and important sources of nutrition in South America and have potential in countries outside their center of origin. We conducted a two-part study on oca (Oxalis tuberosa), mashua...

  • Estuaries in Motion : Teaching Estuarine Flow Concepts through Video

    Creator:
    Cameron, Marina R.
    Abstract:
    A short (approximately 8 minute) video was created to explain key concepts in estuarine flow and numerical modeling of estuaries for high school students. Animation, real picture videography, and numerical model outputs were used to illustrate how scientists use physics and physics models to understand how flow in an estuary...

    Creator:
    Carson, Ann M.
    Abstract:
    In an increasing sedentary society, it is becoming even more important to encourage adolescent girls to participate and value physical activity. This document provides a study grounded in scholarly research exploring issues of importance to the promotion and implementation of programs relevant to motivating girls to be physically active, specifically...
