  • Comparison between lichen, conifer needles, resin-based passive air sampling devices (PASDs), and snow to monitor semi-volatile organic compounds (SOCs) in the atmosphere

    Creator:
    Schrlau, Jill E.
    Abstract:
    The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...

  • Husbandry stress of Zebrafish, Danio rerio

    Creator:
    Ramsay, Jennifer Mara
    Abstract:
    Zebrafish, Danio rerio, are widely used as vertebrate research organisms yet little is know about their responses to husbandry stressors. This dissertation examined the whole-body cortisol responses of zebrafish to husbandry stress. Additionally, the effects of stress on the susceptibility to mycobacteriosis and microsporidiosis (Pseudoloma neurophilia) were determined including effects...

  • Seasonal floodplain wetlands as fish habitat in Oregon and Washington

    Creator:
    Baker, Cynthia F.
    Abstract:
    To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...

  • Analysis of semi-volatile organic contaminants and their accumulation in remote aquatic ecosystems of the western US

    Creator:
    Ackerman, Luke K.
    Abstract:
    Many pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons are persistent, bio-accumulative, and toxic. These semi-volatile organic compounds (SOCs) can undergo atmospheric transport and deposition in cold, remote ecosystems. A better understanding of their accumulation in the fish of these ecosystems is important to better predict...
