The Roles of Recruitment, Species Interactions, and Oceanographic Context in Structuring Rocky Intertidal Communities of the Pacific Northwest and Atlantic Canada

Creator:: Meunier, Zechariah D.
Abstract:: Long-term, large-scale studies of meta-ecosystems provide critical information about how global change influences communities. In my dissertation, I analyzed data from studies encompassing 18 years (2006 – 2023) and over 1,000 km of coastline to investigate drivers of rocky intertidal community structure and dynamics. Specifically, I explored the roles of...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

Diseases of Rhododendron and Boxwood: Survey and Virulence of Phytophthora Root Rot and Management of Boxwood Blight with Systemic Fungicides

Creator:: Sacher, Gabriel
Abstract:: Diseases can be a substantial threat to woody plant production, a major industry in Oregon. Boxwood (Buxus spp.) and rhododendron (Rhododendron subgenus Rhododendron and Hymenanthes) represent the top two broadleaf evergreen woody plants by farmgate value in Oregon. Historically, Phytophthora root rot has been considered the most destructive disease of...

A Quantitative Examination of Campus Racial Climate and Black Women’s Degree Attainment at HSIs in the United States

Creator:: Ellis, Brianna
Abstract:: The purpose of this study was to explore how campus climate at Hispanic-Serving Institutions (HSIs) influences degree completion for Black women. As the number of HSIs has increased in the past decade, there exists a need to understand how Black women fare in such an institutional context. Though there is...

Forage production, dual use potential, and trait variation in chicory grown in the Pacific Northwest

Creator:: Seeno, Elizabeth
Abstract:: Grasslands in the Pacific Northwest are characterized by seasonally wet, acidic soils that mainly support cool season grasses and a limited number of legume species. A major limitation to efficient animal production in grass-dominant pastures is the decline in the herbage growth rate and nutritional quality of forage from late...

Peak reconstruction of single particle mass spectrometry transient signals to recapture ion count and improve SNM ratio measurements

Creator:: Mannino, Mitchell
Abstract:: Quick and accurate measurements of nanoparticles have important applications in biology, environmental and non-proliferation areas. Calculation of isotopic ratios, particularly in special nuclear materials, has relied on integration of nanoparticle counts and limited the capability of counting minor isotopes. Rapid transient detection method of nanoparticles has demonstrated the effectiveness of...

Metagenomics, barcoding, and metabarcoding statistical analysis to facilitate integrative genomic studies of microbial and eukaryotic assemblages

Creator:: Senn, Savanah
Abstract:: The body of work aims to contribute to the area of Quantitative analysis in Environmental Sciences, and is focused on the microbiome. The underlying theme for the dissertation is methods and workflow. The unique bioinformatics workflow used for the analysis of genomic data was used to answer distinct and pressing...

Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

Cooperation and Conflict Dynamics in Small-Scale Fisheries

Creator:: Villegas, Ciera A.
Abstract:: Small-scale fisheries account for at least 40 percent of global fisheries catch, 90 percent of the people employed along capture fisheries value chains operate in small-scale fisheries, and 45 million women participate in small-scale fisheries globally. The past few years have brought warnings from policymakers and resource managers about risks...
