  • An Investigation of Stage 0 Restoration in California and Oregon

    Creator:
    Schneider, Charles W.
    Abstract:
    Stream restoration efforts have increasingly started to focus on management actions that restore ecological function rather than focusing on species-specific habitat needs. Restoration practitioners in the Pacific Northwest have implemented numerous large-scale floodplain restoration projects to restore stream function at the valley scale. Some of these projects attempt to restore...

  • Post-Preservation Maintenance of Cadavers to Prevent Tissue-Dehydration in Educational Environments

    Creator:
    Herrera, Alexandria R.
    Abstract:
    In anatomical education, clinicians, surgeons, and anatomists support the use of human cadavers over digital or artificial alternatives. Cadaver use raises the challenge of preventing tissue dehydration. The OSU cadaver labs attempt to maintain hydration by re-covering the exposed tissues with original skin, layers of plastic wrap, and/or towels and...

  • Enhancing Detection of Marine Debris with Polarimetric Imagery

    Creator:
    Herrera, Frederick Kyle
    Abstract:
    Marine debris is a chronic and increasingly pervasive problem for coastal regions around the world. Debris poses environmental risks, threats to wildlife, and degradation of the natural environment. Recent research has shown the advantages of uncrewed aircraft systems (UAS) for detection and recognition of marine debris, including the ability to...

  • Use of Landscape Characteristics to Quantify Hybridization Risk Between Native and Introduced Salmonids

    Creator:
    Manning, Michael A.
    Abstract:
    The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data of hybrids occurrences makes assessing hybridization risk difficult. Here, I developed a spatially-explicit GIS Hybridization Risk Model (HRM) between native ESA-listed Bull Trout and introduced Brook Trout by...

  • Downstream Rearing Chinook Salmon (Oncorhynchus tshawytscha) in the Upper Mainstem of the John Day River

    Creator:
    Scheu, Michael P.
    Abstract:
    Juvenile Chinook Salmon (Oncorhynchus tshawytscha) leave the natal reach at different times and move downstream at different rates which can increase their productivity by allowing them to utilize habitats on different temporal scales and spreading risk of localized stochastic events. This life history diversity can also allow fish to adapt...

  • Effects of Stage 0 treatment on spring Chinook juveniles within South Fork McKenzie River in Oregon

    Creator:
    Hahn, Aleah
    Abstract:
    Low-tech habitat restoration techniques, including Stage 0 treatments, are increasingly applied but often lack robust evaluation of their effects. In 2018, one kilometer of the South Fork McKenzie (SFMK) River, OR was modified to the Stage 0 condition for the benefit of ESA-listed Chinook by raising the incised channel to...

  • Non-viral Vectors for Ocular Gene Delivery

    Creator:
    Herrera-Barerra, Marco, F.
    Abstract:
    Nucleic acid therapeutics has cemented itself as one of the most efficacious and robust avenues for treatment of a wide range of diseases from vaccine development to treatment of liver, retina, cancer applications. Non-viral mediated gene delivery using lipid-based nanoparticle (LNP) carriers has proven its compatibility with addressing unexpected, fast...

  • Tide gates : operation, fish passage and recommendations for their upgrade or removal

    Creator:
    Souder, Jon A. and Giannico, Guillermo
    Abstract:
    This document is intended for policymakers so they can make informed decisions about upgrading or removing tide gates in an effort to improve conditions for Oregon’s native migratory fish and other animals and plants that inhabit estuaries. It has two main sections: The first includes an overview of the technical...

  • Detecting Fish Vocalizations in American Samoa Using Machine Learning

    Creator:
    Munger, Jill
    Abstract:
    A deep neural network was developed and trained to identify the sounds of pomacentrids (damselfishes) in the National Park of American Samoa. Four years of continuous, passive acoustic data were recorded by a single stationary hydrophone. Deep neural networks enable the full utilization of such large datasets by automating laborious...

  • The Influence of Wildfire and Invasive Vegetation on Mule Deer

    Creator:
    Schuyler, Elizabeth
    Abstract:
    The western United States has experienced large-scale degradation due to land use and land cover changes, invasion of annual grasses, and expansion of woody plants into grass and shrublands and the resultant altered fire regimes. These landscape-scale changes have coincided with declining mule deer (Odocoileus hemionus) populations, making habitat loss...
