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...

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...

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.

Effects of stress on the reproductive performance and physiology of rainbow trout (Oncorhynchus mykiss)

Creator:: Contreras Sánches, Wilfrido M.
Abstract:: The environment under which fish are maintained as broodstock before reproduction is often stressful; however, the impact of stress on broodstock and gamete quality is not well known. We investigated the effects of stress over the final stages (i.e. the 3 months preceding ovulation) of sexual maturation of female rainbow...

Distribution and life history of the spiny dogfish (Squalus acanthias) off the Oregon and Washington coasts

Creator:: Richards, Jaclyn M.
Abstract:: This study examines the spatial and temporal distribution and life history of the "offshore" component of the Northeastern Pacific spiny dogfish (Squalus acanthias) population. Distribution was examined in relation to latitude, depth, the Columbia River plume and large-scale climate changes. Fishery and survey data indicate that the Northeastern Pacific spiny...
