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...

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.

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...

Mobile Autonomous Passive Acoustic Monitoring of Marine Mammals in the Catalina Basin

Creator:: Edison, Ciera J. and Fregosi, Selene
Abstract:: Traditional visual survey methods for marine mammals can only detect a fraction of the animals present. Even if the animal can be observed from the surface, visual limitations such as time of day and weather conditions can impede this ability. Recent advances in passive acoustic monitoring technologies have led to...

Aging Giant Pacific Octopus using Beaks and Stylets for Better Stock Structure Assessment

Creator:: Yarbrough, Ashley
Abstract:: Despite being a highly charismatic and frequently exhibited organism, Giant Pacific Octopus (Enteroctopus dofleini) population dynamics are poorly understood. Basic monitoring data for this species is limited to bycatch and stomach contents of other fisheries species. An essential step to a better estimation of population size and productivity is to...
