Unprecedented evidence for high viral abundance and lytic activity in coral reef waters of the South Pacific Ocean

Creator:: Payet, Jérôme P., McMinds, Ryan, Burkepile, Deron E., and Thurber, Rebecca L. Vega
Abstract:: Despite nutrient-depleted conditions, coral reef waters harbor abundant and diverse microbes; as major agents of microbial mortality, viruses are likely to influence microbial processes in these ecosystems. However, little is known about marine viruses in these rapidly changing ecosystems. Herewe examined spatial and short-term temporal variability in marine viral abundance...

Host-pathogen Interactions of Respiratory RNA Viruses and the Application of Recombinase Polymerase Amplification for Viral Diagnostics

Creator:: Prescott, Meagan A.
Abstract:: Humans and viral disease are inextricably intertwined. Viral disease plays an immeasurable role in human life, from the disease and economic burden associated with every facet of contending with human viral disease, to managing the consequences of viral disease in organisms important to our food supply, economy, and entertainment. The...

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...

Quantifying Carbon Production in Marine Ecosystems Using Expressions of Phytoplankton Physiology

Creator:: Penta, William Bryce
Abstract:: Phytoplankton initiate the marine carbon cycle by fixing carbon dioxide into biologically available compounds. These abundant single celled organisms mediate carbon flux from the atmosphere to the deep ocean and are the base of the marine food web, supplying new carbon to higher trophic levels. Phytoplankton are highly diverse and...

The Role of the Mucosal Immunoglobulin IgT and Inflammatory Cytokines in Ceratonova shasta Infections in Rainbow Trout

Creator:: Taggart-Murphy, Laura M.
Abstract:: The myxozoan parasite Ceratonova shasta threatens both juvenile and adult salmonid populations in the Pacific Northwest region of the United States, causing intestine necrosis and hemorrhaging, along with high mortality in some fish strains. It induces an inflammatory tissue response in susceptible strains of fish; understanding the interactions between C....

The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

Hydraulic predictors and seasonal distribution of Manayunkia speciosa density in the Klamath River, CA, with implications for ceratomyxosis, a disease of salmon and trout

Creator:: Jordan, Michelle S.
Abstract:: The freshwater polychaete Manayunkia speciosa was identified as an obligate host of the salmonid parasite Ceratomyxa shasta in 1997, prompting increased research on the small benthic invertebrate. Ceratomyxa shasta infection in fish can cause mortality, and presents a disease risk for both hatchery and wild salmon and trout. Ceratomyxa shasta...

Arsenic methylation by marine cyanobacteria Prochlorococcus and Synechococcus

Creator:: Lee, Mikaela
Abstract:: Our experiments aimed to investigate responses of the marine cyanobacteria Prochlorococcus and Synechococcus to toxic arsenic species, such as arsenate, and to understand cellular mechanisms that contribute to arsenic tolerance. We used two strains of Prochlorococcus, a high-light adapted MED4 and low-light adapted MIT9313, both axenic, for cultivation experiments. For...

Comparison of fixatives and fixation time for PCR detection of Mycobacterium in zebrafish Danio rerio

Creator:: Peterson, Tracy S., Kent, Michael L., Ferguson, Jayde A., Watral, Virginia G., and Whipps, Christopher M.
Abstract:: Mycobacteriosis is a common disease of laboratory zebrafish Danio rerio. Different infection patterns occur in zebrafish depending on mycobacterial species. Mycobacterium marinum and M. haemophilum produce virulent infections associated with high mortality, whereas M. chelonae is more widespread and is not associated with high mortality. Identification of mycobacterial infections to...

Multiple Stressors Drive Changes in Coral Microbiome Diversity and Composition Demonstrating the Role of a Bacterial Symbiont in Microbial Community Sensitivity and Resilience

Creator:: Maher, Rebecca L.
Abstract:: On coral reefs, disturbances rarely occur in isolation. Global stressors such as increasing seawater temperature often coincide with local stressors like nutrient pollution. In the face of increasing anthropogenic stress, corals can function as environmental sentinels, although little is known about how multiple stressors interact to disrupt their associated bacterial...
