Genetic Structure, Diversity, and Mating System of Leptasterias: Potential for Local Adaptation?

Creator:: Boring, Emily L.
Abstract:: Understanding of gene flow, connectivity, and diversity is critical to predict the stability of key marine species. The Oregon coast of the U.S.A. shows fine-scale levels of geographic variation in environmental stressors such as temperature, pH, and oxygen levels, prompting questions about the potential for local adaptation. In this thesis,...

The Range, Abundance, Spread, and Biophysical Effects of a Novel, Invasive Beachgrass Hybrid, Ammophila arenaria × A. breviligulata, on U.S. Pacific Northwest Coastal Dunes

Creator:: Askerooth, Risa
Abstract:: Non-native ecosystem engineers, which modify the structure and function of their ecosystems, are often a particularly concerning and costly group of invasive species. Such organisms may have substantial impacts on ecosystem services, or the benefits that humans derive from their ecosystems. Many factors play a role in the invasion success...

Big Fishery, Big Data, and Little Crabs: Using a Genomic Approach to Examine Larval Recruitment Patterns of Dungeness Crab (Cancer magister) in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J.
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. In this thesis, a genotyping-by-sequencing (GBS) approach was used to examine genomic variation in an early life stage of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...

Weevils That Live Under Trees Thrown Out of the Sea: Phylogeny and Microbial Diversity of Sthereus Motschulsky, 1845 and Related Weevils (Curculionidae: Molytinae)

Creator:: Young, Natasha
Abstract:: Here the diversity and phylogeny of the genus, Sthereus Motschulsky, 1845, and its nearest associates in the large subfamily Molytinae are explored through molecular and morphological characters. Sanger sequencing of five genes determined that Sthereus is not monophyletic. Instead, the one species in the genus Gastrotaphrus Buchanan 1936, G. barberi...

Experimental and mathematical procedures for the estimation of shelf-life : application to temperature-abused chilled seafood

Creator:: Almonacid-Merino, Sergio Felipe
Abstract:: The validation and potential use of mathematical models to estimate the shelf-life of refrigerated food exposed to temperature abuse and basing such estimations on microbial growth was analyzed. Combined heat transfer, microbial growth models, and non-parametric statistical procedures formed a computer-based predictive tool to assess shelf-life and estimate the accuracy...

Consequences of Cryopreservation in Diverse Strains of Saccharomyces cerevisiae

Creator:: Wing, Kieslana M.
Abstract:: 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...

Characterizing Microplastic Ingestion in Black Rockfish (Sebastes melanops) along the Oregon Coast

Creator:: Lasdin, Katherine S.
Abstract:: Microplastics (<5mm diameter) are present in a considerable number of marine and aquatic species. Understanding which species, the global spatial distribution, and what quantities of microplastics are present is extremely important for understanding the potential impacts they could have on recreationally important organisms and for the assessment of risk. We...

Arribada nesting of olive ridley sea turtles (Lepidochelys olivacea) at La Escobilla, Mexico

Creator:: Ocana, Melissa Ann S.
Abstract:: Olive ridley sea turtles (Lepidochelys olivacea) present an interesting case study of the conservation of wildlife species that aggregate in high densities and have served as resources for human consumption. Ridleys exhibit synchronized mass-nesting behavior, during events called "arribadas," where thousands of females lay eggs together in a small area...

Hot, hot, heat : evaluating Phoenix, Arizona cooling centers through a project management perspective

Creator:: Leone, Cassandra M.
Abstract:: Global annual average temperatures are rising, creating extreme heat events or heatwaves that are increasing in frequency, length, and severity. The world will endure more of these events as climate change worsens and heat-related mortality and morbidity will increase due to warming conditions. At the center of heatwaves are urban...
