NMR spectroscopy is the go-to technique for determining the solution structures of organic,
organometallic, and even macromolecular species. However, structure determination of nanoscale
aqueous inorganic clusters by NMR spectroscopy remains an unexplored territory. The few hydroxobridged
inorganic species well characterized by ¹H Nuclear Magnetic Resonance spectroscopy (¹H-NMR)
do not provide...

Microbial ecology has been transformed by metagenomics, the study of the genetic in-formation in entire communities of organisms. In the following we develop metagenomic tools arising from the classic Wasserstein metric as applied to questions regarding the diversity between microbial communities. We provide a novel proof of the characteriza-tion of...
Uncertainties in the age and phylogenetic position of Pinaceae fossils present significant obstacles to our understanding of the timing of diversification in the family. We demonstrate that simultaneous phylogenetic analyses of chloroplastDNA(matK and rbcL) and nonmolecular characters that include both extant genera and a limited number of fossil taxa provide...
Urban areas currently cover a small fraction of Oregon’s landscape but will expand to accommodate an increasingly large proportion of the state’s growing population and economic activity. Residential developments on rural lands now cover more than twice the area occupied by Oregon’s urban developments and are growing rapidly. Oregon urban...
This document provides definitions and a general overview of streams and lakes of San Juan County (SJC) and then describes impacts to these water bodies and strategies for determining widths of buffers that protect their functions. It similarly provides definitions and a general overview of SJC upland (terrestrial) habitats, describes...
The emerging field of regenerative medicine is mainly approached by two different aspects. First is the use of stem cell based models to generate a suite of differentiated cells for therapeutic applications and the alternative approach is to utilize the non-mammalian models that have the inherent capacity to regenerate their...
Multiple factors are known to influence student success in higher education. Barriers to postsecondary success for underrepresented STEM students are numerous and well documented. We detail an exploratory study of STEM faculty notions of successful students and the instructional practices they employ to cultivate student success. We use a conceptual...
Simulations of past climates require altered
boundary conditions to account for known shifts in the Earth
system. For the Last Glacial Maximum (LGM) and subsequent
deglaciation, the existence of large Northern Hemisphere
ice sheets caused profound changes in surface topography
and albedo. While ice-sheet extent is fairly well
known, numerous...
This research investigates the physiological and transcriptional responses of Nitrosomonas europaea when exposed to chlorinated aromatic compounds and heavy metals under varying environmental conditions. It was found that transcriptional responses of identified sentinel genes correlate well with nitrification inhibition. Sorption of metals to biomass was also investigated and found not...
