Using DNA metabarcoding to describe biodiversity and disease dynamics

Creator:: Massey, Aimee L.
Abstract:: Land-use change, particularly in the form of the conversion of primary forest to forest-matrix systems, alters species communities and species interactions. Describing these often complex and nuanced species responses is one of the great challenges in ecology. Another complementary challenge is finding and using the most efficient means for collecting...

Conceiving A Colony: A Multi-Level Biocultural Analysis of the Maternal Stress-Preterm Birth Nexus in Puerto Rico

Creator:: Horan, Holly L.
Abstract:: This dissertation aims to elicit how a neo-colonial context shapes maternal and infant heath (MIH) outcomes by describing how they are socially, politically, historically, and culturally produced. Using a multi-level critical biocultural, medical anthropological research approach, the purpose of this research was to investigate maternal stress in the United States...

The relationships between fluctuations in oceanographic conditions, forage fishes, predatory fishes, predator food habits, and juvenile salmonid marine survival off the Columbia River

Creator:: Emmett, Robert L.
Abstract:: Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...

Stability and biological responses of zinc oxide metalworking nanofluids (ZnO MWnF™)

Creator:: Niyaghi, Faraz
Abstract:: Zinc oxide nanoparticles (ZnO NPs) have demonstrated the ability to improve lubrication and thermal conductivity, and stand as promising metalworking lubricant and coolant additives due to their low cost compared to other NPs. While nanomaterials are a focus of research due to their potential to enable advanced technologies, little is...

Large Downed Wood as Post-fire Refugia for Terrestrial Salamanders in Pacific Northwest Forests

Creator:: Stephens, Paige N.
Abstract:: Climate change, wildfire, timber harvest, and land conversion alter the availability of downed wood in forests of the western United States. Numerous taxa rely on downed wood for temperature and humidity refugia, and downed wood may play a key role in enabling the persistence of climate-sensitive, low-vagility species like terrestrial...

Effects of Diversity on Emerging Infectious Diseases of Amphibians

Creator:: Snyder, Paul W.
Abstract:: Species declines and extinctions have been recorded across taxa as evidence of an ongoing global biodiversity crisis. Amphibians are at the forefront of these declines with nearly one third of amphibian species estimated to be at risk of extinction. While many factors contribute to population declines and extinctions, the role...

The Primacy of Mammals as Seed Dispersers and Predators in Salmon-Bearing Ecosystems

Creator:: Harrer, Laurie E. F.
Abstract:: Plants often encase seeds in a nutritional reward to incentivize seed dispersal by birds and mammals, but these seeds may also be removed and destroyed by seed predators. Although birds are typically thought to be the primary seed dispersers of berries in temperate systems, in southeast Alaska and other salmon-bearing...

A local perturbation problem of the 3D Navier-Stokes equations

Creator:: Zeng, Jhih-Jyun
Abstract:: This dissertation explores mathematical theory of the 3 dimensional incompressible Navier-Stokes equations that consists a set of partial differential equations which govern the motion of Newtonian fluids and can be seen as Newton's second law of motion for fluids. The main interest of this work focuses on how local perturbation...

Water intake structures as movement barriers for larval coastal giant salamanders (Dicamptodon tenebrosus)

Creator:: Eaton, Jordan E.
Abstract:: Dams, culverts, and water intake structures can impact the movement of aquatic and semi-aquatic species within streams and rivers. Datagaps exist regarding the impact of water intake structures on larval coastal giant salamanders (Dicamptodon tenebrosus) as these obstructions may produce a barrier to up and downstream movement. The Rock Creek...

A Comparative Study of Foraging Behavior and Disturbance Regimes in Urban Versus Agricultural Habitats used by Cackling Geese Wintering in the Willamette Valley, Oregon

Creator:: Harrington, Erin R.
Abstract:: The Cackling goose (Branta hutchinsii minima) population has increased from a low of 20,000 in 1984 to the current population of 220,000-300,000 (Stehn 2012, Sanders 2013). As the Cackling goose population began to recover in the late 1990s, the majority of the population relocated from wintering in California to the...
