Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:

Cummings, Brittany M.

Abstract:

Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...

Effect of metformin exposure on growth and photosynthetic performance in the unicellular freshwater chlorophyte, Chlorella vulgaris

Creator:

Cummings, Brittany M., Needoba, Joseph A., and Peterson, Tawyna D.

Abstract:

Many pharmaceuticals have negative effects on biota when released into the environment. For example, recent work has shown that the commonly prescribed antidiabetic drug, metformin (N,N-dimethylbiguanide), has endocrine disrupting effects on fish. However, effects of metformin on aquatic primary producers are poorly known. We exposed cultured isolates of a freshwater...

Persistent spatial structuring of coastal ocean acidification in the California Current System

Creator:

Washburn, L., Russell, A., Menge, B. A., Hill, T., Cheriton, O., Nielsen, K. J., McManus, M. A., Feely, R. A., Gouhier, T., Byrne, R. H., Friederich, G., Sanford, E., Hacker, S., Chan, F., Blanchette, C. A., Gaylord, B., Barth, J. A., Sevadjian, J., Hofmann, G., and Chavez, F.

Abstract:

The near-term progression of ocean acidification (OA) is projected to bring about sharp changes in the chemistry of coastal upwelling ecosystems. The distribution of OA exposure across these early-impact systems, however, is highly uncertain and limits our understanding of whether and how spatial management actions can be deployed to ameliorate...

Draft Genome Sequence of Streptomyces sp. Strain ventii, Isolated from a Microbial Mat near Hydrothermal Vents within the Axial Seamount in the Pacific Ocean, and Resequencing of the Type Strains Streptomyces lonarensis NCL 716 and Streptomyces bohaiensis 11A07

Loughran, Rachel M., Mitchell, Edward A., Vining, Oliver B., Gallegos, David A., Deadmond, Monica C., Wasson, Benjamin J., Pfannmuller, Kaysa M., Paddock, Brie E., Koyack, Marc J., Oline, David K., Ushijima, Blake, Saw, Jimmy H., McPhail, Kerry L., and Videau, Patrick

Abstract:

The draft genome of Streptomyces sp. strain ventii, an environmental isolate recovered from deep-sea hydrothermal vents in the Pacific Ocean, is presented along with the resequenced draft genomes of the type strains Streptomyces bohaiensis 11A07 and Streptomyces lonarensis NCL 716.

Big fishery, big data, and little crabs : using genomic methods to examine the seasonal recruitment patterns of early life stage dungeness crab (Cancer magister) in the California Current ecosystem

Creator:

Lee, Elizabeth M. J. and O'Malley, Kathleen

Abstract:

The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. Here, a genotyping-by-sequencing (GBS) approach was used to examine genomic variation in an early life stage (megalopae) of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial fishery...

Fine-scale spatial and temporal genomic variation among Dungeness crab Cancer magister larval recruits in the California Current Ecosystem

Creator:

Lee, Elizabeth M. J. and O'Malley, Kathleen G.

Abstract:

Dynamic marine environments can shape complex spatial and temporal patterns in the population connectivity of marine species, and this is often exemplified in species with long larval phases. Here, we used a genotyping-by-sequencing (GBS) approach to examine fine-scale spatial and temporal genomic variation among Dungeness crab Cancer magister larval recruits...

Discovery of a dune-building hybrid beachgrass (Ammophila arenaria × A. breviligulata) in the U.S. Pacific Northwest

Creator:

Mostow, Rebecca S., Barreto, Felipe, Biel, Reuben, Meyer, Eli, and Hacker, Sally D.

Abstract:

The production of novel hybrid zones is an ecologically important consequence of globally increasing rates of species introductions and invasions. Interspecific hybridization can facilitate gene flow between parent species or produce novel taxa that may alter invasion dynamics or ecosystem services. The coastal sand dunes of the U.S. Pacific Northwest...

A Comparison of Bulk Estuarine Turnover Timescales to Particle Tracking Timescales Using a Model of the Yaquina Bay Estuary

Creator:

Lemagie, Emily P. and Lerczak, James A.

Abstract:

The ability to determine a bulk estuarine turnover timescale that is well defined under realistic conditions is in high demand for estuarine research and management. We compare how turnover timescales vary with tidal and river forcing from idealized forcing scenarios using a three-dimensional circulation model of the Yaquina Bay estuary...

What's streamflow got to do with it? A probabilistic simulation of the competing oceanographic and fluvial processes driving extreme along-river water levels

Creator:

Serafin, Katherine A., Ruggiero, Peter, and Parker, Kai

Abstract:

Extreme water levels generating flooding in estuarine and coastal environments are often driven by compound events, where many individual processes such as waves, storm surge, streamflow, and tides coincide. Despite this, extreme water levels are typically modeled in isolated open-coast or estuarine environments, potentially mischaracterizing the true risk of flooding...

The Dynamics and Impact of Ocean Acidification and Hypoxia: Insights from Sustained Investigations in the Northern California Current Large Marine Ecosystem

Creator:

Chan, Francis, Barth, John A., Kroeker, Kristy J., Lubchenco, Jane, and Menge, Bruce A.

Abstract:

Coastal upwelling ecosystems around the world are defined by wind-generated currents that bring deep, nutrient-rich waters to the surface ocean where they fuel exceptionally productive food webs. These ecosystems are also now understood to share a common vulnerability to ocean acidification and hypoxia (OAH). In the California Current Large Marine...
