New discovery leads to a whole new meaning of “trash fish”

Creator:: Chione, Andrew
Abstract:: This paper is an assignment for my Ichthyology class at Oregon State University. I was tasked with creating a new fish species that is scientifically possible and telling a fictional story of its discovery.

Environmental DNA: testing assumptions with experimentation

Creator:: Cousins, Christopher D.
Abstract:: This study used a factorial mesocosm design to quantify American bullfrog (Lithobates castebeianus) eDNA to assess the relationship between body size, density, and eDNA shedding rates.

Evaluating desiccated cyanobacteria Aphanizomenon flos-aquae for use as a biofertilizer on Swiss Chard

Creator:: Turk, Douglas E.
Abstract:: Non-toxic species of desiccated blue-green algae, or cyanobacteria, may offer potential for use as a fertilizer on irrigated crops. Here, the non-toxic cyanobacteria species Aphanizomenon flos-aquae (AFA), collected from Upper Klamath Lake, Oregon, was evaluated for use as a biofertilizer in a controlled experiment on Swiss chard “Bright Lights” (Beta...

eDNA as a tool for identifying freshwater species in sustainable forestry: A critical review and potential future applications

Creator:: Coble, Ashley A., Flinders, Camille A., Homyack, Jessica A., Penaluna, Brooke E., Cronn, Richard C., and Weitemier, Kevin
Abstract:: Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...

Predicting the stability, equilibrium response, and nonequilibrium dynamics of ecological systems

Creator:: Hosack, Geoffrey R.
Abstract:: In this dissertation, new theory and its applications are developed to predict three properties of complex ecological communities: stability, equilibrium response, and non-equilibrium dynamics. First, a graph-theoretic analysis identifies the interconnections in a complex ecosystem that promote or diminish stability (Chapter 2). The hierarchy of interactions that influences stability and...

Parasite communities indicate effects of cross-shelf distributions, but not mesoscale oceanographic features on northern California Current mid-trophic food web

Creator:: Jacobson, Kym C., Baldwin, Rebecca E. B., and Reese, Douglas C.
Abstract:: Mesoscale physical oceanographic features, such as jets and eddies, can influence the structure of marine ecosystems. We used trophically transmitted parasite communities of pelagic fishes in the northern California Current to examine effects of physical oceanographic features on pelagic ecosystem structure. We tested the hypotheses that (1) oceanographic features associated...

Dissolved oxygen requirements of freshwater fishes

Creator:: Doudoroff, Peter and Shumway, Dean L.
Abstract:: This critical review of literature on dissolved oxygen requirements of freshwater fishes is one of a series of papers on water quality criteria, the formulation of which is a prerequisite to the control of water pollution. It was prepared for FAO by the State of Oregon (acting by and through...

Long-term colonization of a subarctic pre-planned artificial reef system in Whittier, Alaska

Creator:: Levy, Charlotte S. and Brown, Eloise J.
Abstract:: ABSTRACT: In 2006 Alaska’s first artificial reef (AR) was deployed as mitigation for habitat lost due to coastal development. Surveys conducted the following year suggested AR assemblages resembled those of adjacent natural reefs (NR). However, there is little known about the ecological succession of AR’s long-term in high latitude locations....

Using quadrats and GPS to assess the abundance of rodent holes in different habitats

Creator:: Dally, Morgan E.
Abstract:: 2018 Library Undergraduate Research Awards nomination materials, reflective learning essay, and research paper. In this study, pocket gopher and gray-tailed vole holes and hills were counted within four distinct habitats using quadrats and a gridding method over a period of five field days. The study was conducted to determine which...

Distribution of juvenile salmonids and stream habitat relative to 15-year-old debris-flow deposits in the Oregon Coast Range

Creator:: Kirkby, Kristen-Marie S.
Abstract:: Debris flows, common disturbances in many mountainous areas, initially scour or bury stream habitats; however, debris flows deliver vast amounts of wood, boulders, and gravel that may ultimately form complex stream habitat to potentially support a diverse salmonid assemblage. The materials deposited by debris flows would otherwise be inaccessible to...
