The introduction of myxozoan parasites through the release of feeder goldfish (Carassius auratus)

Creator:: Karandashova, Sophia
Abstract:: Myxozoa have been found worldwide; these parasites infect a wide variety of hosts, but have been found most often in fish. Carassius auratus (goldfish), a popular aquarium fish and a widespread invasive species, have been identified as an intermediate host for several myxozoan species. Some myxozoan parasites are pathogenic and...

A genomic and proteomic characterization of the first cultured oligotrophic marine Gammaproteobacterium from the SAR92 clade

Creator:: Mellbye, Brett L.
Abstract:: High-throughput culturing (HTC) consisting of extinction culturing in autoclaved seawater has led to the isolation and characterization of many novel strains of oligotrophic marine bacteria. Strain HTCC 2207 was isolated from the Oregon coast by the HTC method. Phylogenetic analysis based on 16S rRNA gene sequence showed that this strain...

Evaluation of ECOSTRESS products for estimation of leaf and grape water stress for Southern Oregon vineyards

Creator:: Swafford Steffensen, Collen
Abstract:: Accurate estimation of water stress in vineyards could prove vital for optimizing irrigation and grape quality in a changing climate. The ECOsystem Spaceborne Thermal Radiometer Experiment on the Space Station (ECOSTRESS) offers potential to remotely sense vineyard water stress but lacks validation against in-field measurements in vineyards. In this study,...

Kinetics of plankton respiration across gradient of anoxic to oxic conditions

Creator:: Jayawickrama, Clare
Abstract:: Ocean deoxygenation is predicted to increase in severity over the next few decades, posing a threat to marine life and fishing economies. Improved predictions of ocean deoxygenation depend on a better understanding of the biogeochemical mechanisms that underly this process. Within the realm of biogeochemical mechanisms, this project specifically investigated...

The Usefulness of Stable Water Isotopes in Improving Drought Prediction

Creator:: Adams, Logan
Abstract:: Drought represents an import part of natural hydrologic cycles that govern the rate and transportation of water on global and regional scales. (Trenberth, et al. 2015) Agriculturally, drought represents a threat to crop production and can endanger political and economic stability through the loss of resources and the threat of...

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...

Predicting Watershed Characteristics Using Bacterial DNA

Creator:: Chadwick, Jessica A.
Abstract:: This study was conducted to determine if bacterial DNA present streams could be used to predict upstream watershed characteristics. Previous studies have found that bacterial composition in soil is influenced by land use. It was hypothesized that if the bacteria present in a stream is known that it can be...

The Dynamics of Random Pulse-Coupled Oscillator Networks

Creator:: Kadhim, Kyra L.
Abstract:: The pulse-coupled oscillator model is widely used to simulate the dynamics of neural systems. For networks with particular internal (Mirollo-Strogatz) dynamics, I will define three broad patterns of collective behaviors found in literature in terms of inter-spike interval (ISI) statistics. These patterns are i) temporally-regular, characterized by all oscillators in...

Characterizing Growth Promoters and Inhibitors of SAR11 Pelagibacter sp. HTCC7211

Creator:: Lee, Connie
Abstract:: SAR11 is a clade of marine bacteria that are the most abundant heterotrophs in ocean surface water. They play a significant role in marine carbon cycling. Although many culturing experiments have been done on SAR11, there was no research that focused on verifying the observations about inhibition of SAR11 growth...

Importance of TLR2 and TLR4 signaling against M. abscessus infection of macrophages and use of mycobacteriophage genomics toward understanding some of the aspects of phage therapy

Creator:: Kapoor, Hannah A.
Abstract:: Mycobacterium abscessus (MAB) is an opportunistic pathogen responsible for infections in immunocompromised or immunosuppressed patients. Even with long-term treatment with multiple antibiotics, MAB pulmonary infections have high rates of treatment failure. Within the host, MAB is phagocytosed by key innate immune cells macrophages. The TLR2 and TLR4 are two critical...
