Developmental effects of micro- and nanoscale tire particles and recycled rubber on zebrafish

Creator:: Mottern, Taylor H.
Abstract:: Plastics have become an essential part of everyone lives, found in almost every product made today. Tires only make up a fraction of these products but as their use increasing so does the microplastics that flake off. Many studies have evaluated the toxic effects of tire particles on aquatic environments...

Low-frequency Teleseismic and Infrasound Arrivals along the Dense Corvallis Nodal Array

Creator:: Way, Rachel
Abstract:: The dense Corvallis array deployed in January of 2022 aided in the high-resolution study of local geology. This array was made of 177 SmartSolo 3-component 5 Hz geophones around Corvallis, with a 93 geophone profile going west towards Bald Hill for approximately 5 km at an average of 64 m...

Evaluation of Oxidation Reduction Potential in Metabolic Syndrome Subjects Compared with Matched Normal Subjects

Creator:: Cobb, Tora Jean
Abstract:: This study was conducted to assess whether healthy adults compared with those with Metabolic Syndrome (MetS) have different mean oxidative-reductive potentials. Static oxidation-reduction potentials and capacity oxidation reduction potentials (sORP and cORP, respectively) were measured in plasma samples. The RedoxSYS® measures sORP in millivolts (mV), which is proportional to the...

Stand Structure of Old Growth Dry Mixed Conifer Forests in the Deschutes and Ochoco National Forests

Creator:: Merschel, Andrew G.
Abstract:: Old-growth dry-mixed conifer forests are valued as habitats for late seral forest species, for the ecosystem services and landscape diversity they provide, and for their aesthetic appeal. The structure of these forests has been heavily altered by historic logging of overstory ponderosa pine and Douglas-fir. Additionally, changes in fire regime...

Evaluating the response of bees to visual attractants in resource-poor environments

Creator:: Parvin, Lucas
Abstract:: Bee populations are declining around the globe, while the need for their pollination services is increasing with growing food demands by an expanding population. There is a need for innovative practices to increase pollination in agricultural environments without harming wild bee populations. However, the use of artificial visual attractants has...

Geographic variation in the seed mycobiome of Coastal Douglas-fir (Pseudotsuga menziesii var. menziesii)

Creator:: Bergmann, Gillian E.
Abstract:: Seeds are an essential component of plant life histories, and seed endophytes have the potential to influence germination, seedling establishment and development. That said, seed endophytes are a relatively new area of study, both in the factors that influence which taxa are present and how these microbes alter plant function....

Metagenomics and metatranscriptomics of the leaf- and root-associated microbiomes of Zostera marina and Zostera japonica

Creator:: Wojahn, John Michael Adrian
Abstract:: A great deal of research has been focused on the microbiomes of terrestrial angiosperms (flowering plants), but much less research has been performed on the microbiomes of aquatic angiosperms (Turner et al. 2013). Eelgrass beds are extremely productive ecosystems that provide habitat for many marine organisms, such as fish, shellfish,...

Analysis of Convolutional Neural Network Image Pre-processing Methods

Creator:: Jacobsen, Matthew
Abstract:: Oceanic plankton have both a large impact on our oceans health and atmo- spheric balance of Co2. The overall health of planktonic life is determined by many physical, chemical, and ecological factors, that drive taxonomic abundances and the relative amount of non-living biomass called detritus. Recent advances in microscopic imaging...

Poly-ion Layers in Layer by Layer Coating of Bacteria : Growth and Zeta Potential

Creator:: Latta, Emma N.
Abstract:: To determine the best poly-ion layers to be used in encapsulation of pyrrolizidine alkaloid degrading anaerobic microbes, a study was carried out to test three layers on coating ability and ability of the bacteria to grow after being coated. Two positive layers, poly(allylamine hydrochloride) (PAH) and poly-L-lysine, and one negative...
