Morphology, Sediment Microbial Analysis, and Species Distribution Modeling of a New Offshore Population of Ghost Shrimp (Neotrypaea sp.)

Creator:: Hardisty, Sarah
Abstract:: In 2019, a multi-cohort population of the typically estuarine burrowing shrimp Neotrypaea sp., was discovered approximately 7 miles offshore of Newport, Oregon. Morphological analysis of the offshore population, microbial sediment sequencing, and species distribution modeling was conducted with this new offshore population. In order to identify Neotrypaea sp. to the...

Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

Creator:: Kopper, Neil H.
Abstract:: Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...

Beyond high hopes : educational attainment among children of immigrants

Creator:: Feeney, Sarah L.
Abstract:: In light of broadening racial/ethnic educational attainment gaps, growing diversity within young populations, and the increasingly critical relationship between higher education and outcomes in adulthood, understanding the factors that shape educational attainment is an especially important task for research. With this goal in mind, the current study examined how national...

From Micro to Macro: Insights into Biogeochemical Mechanisms that Shape Marine Systems

Creator:: Seabrook, Sarah
Abstract:: Biogeochemical mechanisms employed by key organisms, or symbiotic associations of organisms, transform the function and structure of their environment through processes recognized as ecosystem engineering. This dissertation seeks to investigate organism-ecosystem interactions that serve globally significant ecological functions in marine systems and impact how systems respond to environmental change. Using...

Development and validation of a fatigue reliability method for bridging materials

Creator:: Gallops, Sarah
Abstract:: Toughened ceramics, or bridging ceramics, are being developed in an attempt to widen the application base of traditional ceramics, which are brittle and have low resistance to crack extension. The crack growth resistance of these extrinsically toughened ceramics has been shown to increase with crack length, and unlike traditional ceramics,...

Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....

Factors affecting the Ceratomyxa shasta infectious cycle and transmission between polychaete and salmonid hosts

Creator:: Bjork, Sarah J.
Abstract:: Ceratomyxa shasta is a myxozoan parasite that infects salmonid fishes causing the disease ceratomyxosis that is characterized by severe hemorrhage and necrosis of the intestine and death of the fish host. Ceratomyxa shasta is endemic to the Pacific Northwestern United States and Canada, where epizootics are reported for both wild...

Investigation of the Patterns and Transcriptional Regulators from Gene Expression Profiles of Adult Murine Soleus and Tibialis Anterior Skeletal Muscles

Creator:: Alto, Sarah I.
Abstract:: Skeletal muscles provide several functions, including, yet not limited to, voluntary body movement and locomotion, posture and body position, and soft tissue support. Skeletal muscles also play a role in metabolism, requiring energy to facilitate contraction. Each skeletal muscle serves a different purpose despite seeming to perform the same task....

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

Creator:: Roberts, Jed T.
Abstract:: The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...
