Aquaculture has been the world's fastest growing food production technology in recent decades and the effects of its developments are felt in seafood markets worldwide. As a result, fishermen face an additional challenge that has the potential to impact their choice of whether to reduce participation, what species to target,...
An important goal of evolutionary biology is to identify the genetic mechanisms underlying phenotypes in organisms. Understanding adaptation to osmotic stress has many applications, since this stress affects almost all organisms on Earth. By studying the model organism Saccharomyces cerevisiae using experimental evolution, we can learn about genetic mechanisms driving...
Metacercariae of an unidentified species of Apophallus Luhe, 1909 are associated with overwinter mortality in coho salmon, Oncorhynchus kisutch (Walbaum, 1792), in the West Fork Smith River, Oregon. We infected chicks with these metacercariae in order to identify the species. The average size of adult worms was 197 x 57...
There could be a geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in the United States. Marine renewable energy generation efforts are currently being planned, studied, and initially implemented in the country as a response to climate change. The Bureau of Ocean Energy Management is...
There is significant interest in the fabrication of nano- and micro-structured silica with spatially ordered features, which exhibit enhanced optoelectronic properties with application to the next generation of display devices, semiconductors, and sensors. Currents methods of fabrication employ top down processes which use extremes of temperature, pressure, and power. There...
This focus group study examined the social experiences of 10 adolescents ages 12-17 with Moebius Syndrome, a rare condition involving congenital facial paralysis. Content analysis revealed five themes: social engagement/disengagement; resilience/sensitivity; social support/stigma; being understood/misunderstood; and public awareness/lack of awareness of Moebius Syndrome. Compared to previous research on adults with...
Proceedings of the Eighteenth Biennial Conference of the International Institute of Fisheries Economics and Trade, held July 11-15, 2016 at Aberdeen Exhibition and Conference Center (AECC), Aberdeen, Scotland, UK.
Experimental evolution is a tool that allows us to measure changes in populations over time in controlled, novel environments. Microbial evolution experiments use cryopreservation – storage at -80°C in glycerol media – to archive experimental populations. Research with Escherichia coli suggests that cryopreservation conditions can affect cell viability and that...
Landfill leachate is a complex wastewater that contains high levels of ammonium (often over 250 ppm) and trace heavy metals (usually under 0.2 ppm). Microalgae have been shown to inexpensively and effectively treat wastewaters containing high loads of organics and nutrients, as well as adsorb metal ions. This thesis focuses...
