The Genomic Capabilities of Microbial Communities Track Seasonal Variation in Arctic Lagoons

Creator:: Baker, Kristina D.
Abstract:: The lagoons spanning Alaska’s Beaufort Sea coast provide a unique habitat for arctic wildlife. These lagoons and the food webs they support face extreme seasonality with nine months of ice cover followed by a spring thaw that pulses a large amount of freshwater and nutrients into the lagoons. Bacteria link...

Consequences of Influenza A Virus on Pneumococcal Biofilm Formation and Stability in the Absence of Host Factors

Creator:: Nutter, Laura
Abstract:: Streptococcus pneumoniae and Influenza A Virus both primarily infect the upper respiratory tract, with more severe disease occurring during coinfection than would be caused by either pathogen independently. Until recently, characterization of the interactions between these two pathogens has occurred exclusively in the context of a host or using host-derived...

Impact of Dansgaard-Oeschger and Heinrich Events on the Latitudinal Distribution of Methane Sources during Marine Isotope Stage 3

Creator:: Edwards, Jon S.
Abstract:: Understanding how the latitudinal distribution of methane sources changed between stadial and interstadial climate states during the last glacial period can provide important clues about how terrestrial hydroclimate and ecosystems evolved between these different states. The punctuation of the millennial-scale structure by Heinrich events is also of interest in this...

Strategies for Altering Energy Flux in Thalassiosira pseudonana Elucidated by Transcriptomics

Creator:: Pombrol, Michelle
Abstract:: Diatoms play a major role in ocean biogeochemical cycles and are important tools in bioengineering for natural products and nanotechnology. Diatoms and other algae growing at varying resource-limited growth rates allocate carbon to different metabolic pathways to optimize growth; however, the molecular mechanisms controlling these pathway gating strategies are not...

The Impact of Surface Ocean Mixing on Phytoplankton Communities and Associated Carbon Pools

Creator:: VerWey, Brian J.
Abstract:: Deep mixing events in the ocean’s surface layer act as physical drivers of carbon export by detraining dissolved and particulate organic matter, including surface phytoplankton communities, to depth. Once removed from the sunlit surface ocean environment, phytoplankton accumulation rates are dependent on the relative contributions of loss processes, such as...

Species- and Temporal-Specific Coral Microbiome Fluctuations in Response to a Natural Bleaching Event

Creator:: Ewton, Erica M.
Abstract:: Corals provide a diversity of ecosystem services, are among the most biologically diverse ecosystems on Earth, and directly support ~500 million people globally; however, corals are increasingly experiencing significant threats and are undergoing severe bleaching events as the result of the warming climate. Using a two-year data set surrounding a...

Characterizing spin-orbit torques in β-W/Ta/CoFeB/MgO devices

Creator:: Allen, Shane R.
Abstract:: Materials with a strong spin Hall effect and Rashba-Edelstein effect have the potential to improve the efficiency of solid-state magnetic memory technologies and other magnetic logic devices. Heavy metals have been identified as having these properties, including the beta crystal phase of tungsten. In this work, we determine the strength...

Intraseasonal Oscillations of ~20 days Revisited: The Jet Stream and its Ecological Implications along the Oregon Coast

Creator:: Herweck, Kendra
Abstract:: Intraseasonal oscillations in the atmosphere-ocean system can affect weather patterns and regional ecosystems. In turn, these oscillations can be affected by climate variability, resulting in additive and/or non-linear responses of regional ecosystems to climate forcing. In the Northern California Current, a strong correlation was identified between the location of the...

The Fungal Microbiome Associated with Grapevine Trunk Disease in Oregon Vineyards

Creator:: Zimmerman, Jessie
Abstract:: Grapevine Trunk Diseases (GTDs) are caused by a group of fungal pathogens that attack the xylem tissue of mature grapevines worldwide. In the past 30 years, their incidence has increased, both in emerging grape-producing regions, as well as those with an extended history of viticulture. In the same time span,...

Evidence for Strengthening Hadley Cells and a Westward Expansion of the Walker Circulation from Assimilation of Paleoclimate Proxy Data

Creator:: Horlick, Kaleb A.
Abstract:: A synthesis of over 2000 paleoclimate proxy records is performed via a data assimilation framework that expands upon previous efforts by implementing a suite of physically-based proxy system models, and which provides the first example of an observationally independent, multi-seasonal (DJFM, JJAS) paleoclimate reanalysis. This methodology is contrasted against previous...
