  • Evaluating the response of bees to visual attractants in resource-poor environments

    Creator:
    Parvin, Lucas
    Abstract:
    Bee populations are declining around the globe, while the need for their pollination services is increasing with growing food demands by an expanding population. There is a need for innovative practices to increase pollination in agricultural environments without harming wild bee populations. However, the use of artificial visual attractants has...

  • Adapting the Methylene Blue Sulfide Detection Method for Use in a Microfluidic in-situ Monitoring Device

    Creator:
    Monares, Shane W.
    Abstract:
    Sulfide is an important species to measure in environmental water samples. The spectrophotometric detection method for reduced sulfur species (sulfide) based on generation of methylene blue was adapted to work in an apparatus utilizing microfluidic PDMS mixing and observation cells with flow channels in the 100 μm range. The benefits...

  • The Advantages of Creating a Board of Directors in a Family Business

    Creator:
    Vásquez Solórzano, Juan Gabriel
    Abstract:
    This paper seeks to provide a practical answer to the following question: why create a board of directors in a family business? To achieve this, it summarizes the existing research published in the field of family business governance that directly addresses the beneficial role of the board of directors in...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...
