Catalyst selective and regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates: synthetic and computational studies

Creator:: Gould, Eoin, Walden, Daniel M., Kasten, Kevin, Johnston, Ryne C., Wu, Jiufeng, Slawin, Alexandra M., Mustard, Thomas J. L., Johnston, Brittany, Davies, Tony, Cheong, Paul Ha-Yeon, and Smith, Andrew D.
Abstract:: The regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates is described, with DMAP giving preferential N-carboxylation and triazolinylidenes promoting selective C-carboxylation (both with up to >99 : 1 regioselectivity). An enantioselective O- to C-carboxyl variant using NHC catalysis is demonstrated (up to 92% ee), while mechanistic and DFT studies outline...

Does temperature affect the accuracy of vented pressure transducer in fine-scale water level measurement?

Creator:: Liu, Z. and Higgins, C. W.
Abstract:: Submersible pressure transducers have been utilized for collecting water level data since early 1960s. Together with a digital datalogger, it is a convenient way to record water level fluctuations for long-term monitoring. Despite the widely use of pressure transducers for water level monitoring, little has been reported for their accuracy...

Isotopic constraints on the pre-industrial oceanic nitrogen budget

Creator:: Somes, C. J., Oschlies, A., and Schmittner, A.
Abstract:: The size of the bioavailable (i.e., “fixed”) nitrogen inventory in the ocean influences global marine productivity and the biological carbon pump. Despite its importance, the pre-industrial rates for the major source and sink terms of the oceanic fixed nitrogen budget, N₂ fixation and denitrification, respectively, are not well known. These...

Effect of age-based and environment-based cues on reproductive investment in Gambusia affinis

Creator:: Billman, Eric J. and Belk, Mark C.
Abstract:: We examined the multivariate life-history trajectories of age 0 and age 1 female Gambusia affinis to determine relative effects of age-based and environment-based cues on reproductive investment. Age 0 females decreased reproductive investment prior to the onset of fall and winter months, while age 1 females increased reproductive investment as...

An Evaluation of Putative Sympatric Speciation within Limnanthes (Limnanthaceae)

Creator:: Meyers, Stephen C., Liston, Aaron, and Meinke, Robert
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies within Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

Temporal Gene Expression Variation Associated with Eyespot Size Plasticity in Bicyclus anynana

Creator:: Oliver, Jeffrey C., Ramos, Diane, Prudic, Kathleen L., and Monteiro, Antónia
Abstract:: Seasonal polyphenism demonstrates an organism's ability to respond to predictable environmental variation with alternative phenotypes, each presumably better suited to its respective environment. However, the molecular mechanisms linking environmental variation to alternative phenotypes via shifts in development remain relatively unknown. Here we investigate temporal gene expression variation in the seasonally...

Malonate Inhibits Virulence Gene Expression in Vibrio cholerae

Creator:: Minato, Yusuke, Fassio, Sara R., and Häse, Claudia C.
Abstract:: We previously found that inhibition of the TCA cycle, either through mutations or chemical inhibition, increased toxT transcription in Vibrio cholerae. In this study, we found that the addition of malonate, an inhibitor of succinate dehydrogenase (SDH), decreased toxT transcription in V. cholerae, an observation inconsistent with the previous pattern...

Enhancing the T-shaped learning profile when teaching hydrology using data, modeling, and visualization activities

Creator:: Sanchez, C. A., Ruddell, B. L., Schiesser, R., and Merwade, V.
Abstract:: Previous research has suggested that the use of more authentic learning activities can produce more robust and durable knowledge gains. This is consistent with calls within civil engineering education, specifically hydrology, that suggest that curricula should more often include professional perspective and data analysis skills to better develop the ‘T-shaped’...

Determinants of moth diversity and community in a temperate mountain landscape: vegetation, topography, and seasonality

Creator:: Highland, Steven A., Miller, Jeffrey C., and Jones, Julia A.
Abstract:: Macromoth diversity, abundance, and community structure in the topographically complex HJ Andrews Experimental Forest and LTER site was studied on the west slope of the Cascade Range, Oregon. Data on 493 macromoth species (62,221 individuals) was sampled eight times/year at 20 locations from 2004 to 2008 and examined using multivariate...
