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...

Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

Creator:: Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
Abstract:: Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

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...

Bat Monitoring in North Coast and Cascades Network Summer 2019

Creator:: Barnett, Emily, Mock, Rayanne, Grigorov, Anastacia, Levorse, Alexis, and Chestnut, Tara
Abstract:: The detection of white-nose syndrome (WNS) in King County, WA in 2016 prompted the National Park Service to mobilize region-wide bat monitoring and disease surveillance. One of the goals of the Pacific West Region WNS response plan was to implement acoustic monitoring to determine the distribution of bat species and...

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.

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...

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....

Long-term Colonization Of A Subarctic Artificial Reef System In Whittier, Alaska

Creator:: Levy, Charlotte S. and Brown, Eloise J.
Abstract:: Over half of the U.S. coastline is found in Alaska, and the majority of the state’s economic activity occurs along the coast. Increased coastal development poses a potential threat to nearshore habitats in Alaska. The installation of artificial reef (AR) systems can mitigate habitat loss; however, few AR systems have...
