Total Synthesis of (±)-Goniomitine via Radical Translocation

Creator:: Vellucci, Jessica K. and Beaudry, Christopher M.
Abstract:: The aspidosperma alkaloid goniomitine was synthesized in six steps from 2-ethyl-δ-valerolactam. The convergent strategy features an Ullman coupling to assemble the required carbon atoms. A complexity-generating radical translocation reaction was used to build the indole architecture.

Manipulating Soil Moisture and Nitrogen Availability to Improve Fermentation Behavior and Wine Quality. Part I: Vine Physiological Performance, Yield Components, Ripening Dynamics, and Fruit Composition

Creator:: Howe, Jessica and Candolfi-Vasconcelos, M. Carmo
Abstract:: This study integrates various vineyard practices that may improve nitrogen availability to the vine, particularly during ripening. Different strategies aimed at improving fermentation behavior and wine quality are being evaluated. This study aims to optimize fruit quality and maximize the juice nitrogen fraction that can be used by yeast during...

Paired stable isotopologues in precipitation and vapor: A case study of the amount effect within western tropical Pacific storms

Creator:: Conroy, Jessica L., Noone, David, Cobb, Kim M., Moerman, Jessica W., and Konecky, Bronwen L.
Abstract:: Understanding controls on the stable isotopic composition of precipitation and vapor in the West Pacific Warm Pool is vital for accurate representation of convective processes in models and correct interpretation of isotope-based paleoclimate proxies, yet a lack of direct observational evidence precludes the utility of these isotopic tracers. Results from...

Influence of sediment characteristics on the composition of soft-sediment intertidal communities in the northern Gulf of Mexico

Creator:: Coblentz, Kyle E., Henkel, Jessica R., Sigel, Bryan J., and Taylor, Caz M.
Abstract:: Benthic infaunal communities are important components of coastal ecosystems. Understanding the relationships between the structure of these communities and characteristics of the habitat in which they live is becoming progressively more important as coastal systems face increasing stress from anthropogenic impacts and changes in climate. To examine how sediment characteristics...

Evidence for selective mortality in marine environments: the role of fish migration size, timing, and production type

Creator:: Claiborne, Andrew M., Miller, Jessica A., Weitkamp, Laurie A., Teel, David J., and Emmett, Robert L.
Abstract:: The underlying causes of mortality during critical life stages of fish are not well understood, nor is it clear if these causes are similar for naturally versus artificially propagated (i.e. hatchery) individuals. To assess the importance of selective mortality related to production type (hatchery vs. naturally produced) and size at...

Assessing the Relative Importance of Local and Regional Processes on the Survival of a Threatened Salmon Population

Creator:: Miller, Jessica A., Teel, David J., Peterson, William T., and Baptista, Antonio M.
Abstract:: Research on regulatory mechanisms in biological populations often focuses on environmental covariates. An integrated approach that combines environmental indices with organismal-level information can provide additional insight on regulatory mechanisms. Survival of spring/summer Snake River Chinook salmon (Oncorhynchus tshawytscha) is consistently low whereas some adjacent populations with similar life histories experience...

When is bigger better? Early marine residence of middle and upper Columbia River spring Chinook salmon

Creator:: Tomaro, Londi M., Teel, David J., Peterson, William T., and Miller, Jessica A.
Abstract:: Early ocean residence is considered a critical period for juvenile salmon although specific survival mechanisms are often unidentified and may vary by species or life stage. Columbia River spring-run Chinook salmon Oncorhynchus tshawytscha abundance has declined dramatically since the early 1900s. To elucidate mechanisms of early marine survival, we tested...

Seasonal cues induce phenotypic plasticity of Drosophila suzukii to enhance winter survival

Creator:: Shearer, Peter W., West, Jessica D., Walton, Vaughn M., Brown, Preston H., Svetec, Nicolas, and Chiu, Joanna C.
Abstract:: Background: As global climate change and exponential human population growth intensifies pressure on agricultural systems, the need to effectively manage invasive insect pests is becoming increasingly important to global food security. Drosophila suzukii is an invasive pest that drastically expanded its global range in a very short time since 2008,...

Histone modifications rather than the novel regional centromeres of Zymoseptoria tritici distinguish core and accessory chromosomes

Creator:: Schotanus, Klaas, Soyer, Jessica L., Connolly, Lanelle R., Grandaubert, Jonathan, Happel, Petra, Smith, Kristina M., Freitag, Michael, and Stukenbrock, Eva H.
Abstract:: Background: Supernumerary chromosomes have been found in many organisms. In fungi, these “accessory” or “dispensable” chromosomes are present at different frequencies in populations and are usually characterized by higher repetitive DNA content and lower gene density when compared to the core chromosomes. In the reference strain of the wheat pathogen,...

Environmental drivers of the fine-scale distribution of a gelatinous zooplankton community across a mesoscale front

Creator:: Luo, Jessica Y., Grassian, Benjamin, Tang, Dorothy, Irisson, Jean-Olivier, Greer, Adam T., Guigand, Cedric M., McClatchie, Sam, and Cowen, Robert K.
Abstract:: Mesoscale fronts occur frequently in many coastal areas and often are sites of elevated productivity; however, knowledge of the fine-scale distribution of zooplankton at these fronts is lacking, particularly within the mid-trophic levels. Furthermore, small (<13 cm) gelatinous zooplankton are ubiquitous, but are under-studied, and their abundances underestimated due to...
