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...

Analysis of SNPs in Mycoplasma cynos strains from canine hosts within the Pacific Coast animal shelter network

Creator:: Prymolenna, Anastasiya V.
Abstract:: Single nucleotide polymorphisms (SNPs) can be used as markers to infer population genetic structure. For Mycoplasma cynos, a pathogen associated with infectious respiratory disease among canines and other animals, SNPs may help to elucidate ecological and evolutionary relationships among the strains that reside in the upper respiratory tract of canines...

Thermal Tolerance and Adaptation in Cnidarians: An Investigation of Host Transcriptomic Responses and Heritable Variation Across Natural Populations

Creator:: Dziedzic, Katherine E.
Abstract:: Coral reefs have become vulnerable to climate change, with mass bleaching events, the loss of symbiotic algae (Symbiodiniaceae), increasing in both frequency and severity. As climate change continues to threaten the persistence and existence of coral reefs around the world, the biggest question posed for coral reefs is “can they...

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...

Metabolic and Immune Responses in Cnidarian-Symbiodiniaceae Symbiosis and Dysbiosis

Creator:: Sawiccy, Valeri
Abstract:: Coral reefs, found in tropical regions, are renowned for their rich biodiversity and their contributions to ecological, cultural, and economic aspects worldwide. The success of coral reefs hinges on the symbiotic partnership between corals and their dinoflagellate algae, from the family Symbiodiniaceae. The algae reside within the coral host’s gastrodermal...

Life in a Rapidly Changing Environment: The Thermal Biology of the Red-sided Garter Snake (Thamnophis sirtalis parietalis)

Creator:: Hubert, David L.
Abstract:: At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...

Hybridization of Non-Native Dune-Building Beachgrasses on the U.S. Pacific Northwest Coast: Characterization of Functional Morphology, Hybrid Swarm Composition, and Ecological Consequences of Ammophila arenaria × A. breviligulata

Creator:: Mostow, Rebecca S.
Abstract:: The rates of biological introductions and invasions are increasing, driving up the associated harms to ecosystems and economies. The spread and effects of invasive organisms depend on the specifics of the introduction, the character of the invaded ecosystem, and multiple traits of the invasive organism itself. One mechanism by which...

16S rRNA Gene Amplicon Sequencing Reveals Trends in Marine Bacterial Diversity and Taxonomic Composition in Natural and Human-built Systems

Creator:: Morelan, Ian A.
Abstract:: Bacteria are abundant in marine environments. They play important roles in nutrient cycling and form symbiotic interactions with eukaryotes. However, the vast majority of bacterial taxa are difficult to maintain in laboratory cultures, meaning that most microbiological research of the past century has focused on a small subset of bacteria....

Science Education Through Comics: Improving Understanding of Current Marine Environmental Issues

Creator:: Schwarz, Zale
Abstract:: According to a 2017 Pew Research Study, 44% of adults in America say that they do not feel informed enough about science to understand news and new discoveries discussed on the media (Funk et al. 2019). This is concerning, because adults are not just passive consumers of media; among other...

Gene expression of four carbonic anhydrase paralogs across the symbiotic states of the model temperate sea anemone, Anthopleura elegantissima (Brandt 1835)

Creator:: Meier, Emily K.
Abstract:: Anthropogenic CO₂ emissions are shifting the global climate equilibrium, causing widespread losses in biodiversity. Anthozoan cnidarians are some of the species most vulnerable to environmental change. Environmental stress causes corals and sea anemones to expel their endosymbiotic algae, which constitute a primary source of nutrition for some Anthozoa. Carbonic anhydrase...

Adaptation to long-term osmotic stress in a domesticated Saccharomyces cerevisiae strain

Creator:: Holman, Douglas S.
Abstract:: Osmotic stress is a common challenge faced by organisms in environments with variable salinity or aridity. Understanding the evolutionary mechanisms underlying adaptation to osmotic stress may have wide applications, including management of populations experiencing climate change, or engineering industrial organisms involved in processes such as fermentation. While Saccharomyces cerevisiae is...

How Nearshore Currents affect Larval Dispersal and Genetic Connectivity of China Rockfish (Sebastes nebulosus) Along Oregon and Washington Coasts

Creator:: Avila, Alexandra M.
Abstract:: Connectivity of fish populations is a crucial question for fisheries conservation and the development of spatial management plans. Both adult and larval movement define the extent and direction of ecological and evolutionary overlap between geographic regions and, therefore, how we define stocks for management purposes. Within that context, my work...

Influence of the Environment and Morphology on Physiological and Genomic Homeostasis in a Temperate Cnidarian-microbe Symbiosis

Creator:: Koch, Jack C.
Abstract:: Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...

Genomic Resource Development and Studies of Thermal Tolerance in Symbiotic Cnidarians

Creator:: Elder, Holland L.
Abstract:: Reef building corals are the foundation of an entire ecosystem, but they are threatened primarily by rising ocean temperatures due to climate change. Corals depend on a thermally sensitive symbiosis with intracellular dinoflagellates. As oceans warm, this symbiosis is disrupted and results in coral mortality, declining populations and degraded reefs....

Stage-structured interactions and their consequences across levels of biological organization

Creator:: Segui, Leah Mupas
Abstract:: A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology assumes that individuals within a species are functionally identical and that consumer-resource dynamics can be predicted solely by using species abundances. However, one species can consist of multiple functional groups,...

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...

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...
