Genetic and morphological evidence suggests cryptic speciation within the Torrent Sculpin, Cottus rhotheus, across the Pacific Northwest

Creator:: Nicholas, Benjamin P.
Abstract:: Dwelling on the bottom of large rivers to high alpine streams, freshwater sculpins (genus Cottus) occur in high densities across the Pacific Northwest, with 21 currently recognized species found in the Pacific Northwest. Sculpin fill many ecological roles, with some species serving as important prey sources, and others competing with...

Aiding Plants and Humans by Targeting Virulence Strategies: Investigation of key protein residues involved in toxoflavin production

Creator:: Justen, Savannah F.
Abstract:: Toxoflavin, a toxic secondary metabolite produced by a variety of bacteria, has been implicated as a causative agent in food poisoning and a virulence factor in phytopathogenic bacteria. This toxin is produced by the tox operon in Burkholderia glumae, in which the encoded protein, ToxD, was previously characterized as essential...

The role of sigma factors in production of cyanobacterial natural products: Escherichia coli as a heterologous expression host

Creator:: Wells, Kaitlyn N.
Abstract:: Cyanobacteria represent an underexploited source of bioactive natural products of interest to the pharmaceutical industry. Lack of development of these compounds as drug leads is due mainly to myriad practical problems with the producing strains including long doubling times, genetic intractability, and low compound yields. Previous attempts at heterologous expression...

Solar Thermal Energy System for Renewable Desalination

Creator:: McLaughlin, Ryan P.
Abstract:: Natural freshwater availability is decreasing as the global population increases. Advances in desalination technologies aim to produce fresh water in an economical way. More sustainable energy sources are desired for these desalination plants to limit the carbon footprint of water production since global carbon dioxide production is exacerbating freshwater scarcity....

Understanding Drivers of Glacier Length Variability Over the Last Millennium

Creator:: Huston, Alan C.
Abstract:: Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation, but when do such changes indicate forced climate change, and when do they indicate natural variability? In this study, we simulate the past ~1000 years of glacier length variability across the globe using the 3-stage...

Systematically evaluating the developmental toxicity of nanomaterials using the zebrafish model

Creator:: Edwards, Sabrina R.
Abstract:: As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...

Isolation and Identification of Indole Metabolites from Pseudomonas fluorescens NZI7

Creator:: Vergis, John M.
Abstract:: Pseudomonas fluorescens NZI7 was first isolated from a New Zealand mushroom farm in 2001. This Gram-negative bacteria can cause brown blotch disease in the basidiomycete mushroom Agaricus bisporus. P. fluorescens NZI7 can also repel grazing by the nematode Caenorhabditis elegans, a natural predator of P. fluorescens NZI7. Potentially implicated in...

Analysis of SNPs in Mycoplasma cynos strains from canine hosts within the Pacific Coast animal shelter network

Creator:: Prymolenna, Anastasiya V.
Abstract:: Single nucleotide polymorphisms (SNPs) can be used as markers to infer population genetic structure. For Mycoplasma cynos, a pathogen associated with infectious respiratory disease among canines and other animals, SNPs may help to elucidate ecological and evolutionary relationships among the strains that reside in the upper respiratory tract of canines...

Reactive Phase Change Materials for Enhanced Thermal Energy Storage

Creator:: Drake, Griffin S.
Abstract:: Effective storage and release of low-to-moderate temperature thermal energy (e.g. solar thermal or geothermal) could be transformational for applications such as space heating/cooling, domestic hot water, or off-grid cooking. Good candidates for thermal energy storage in this temperature range include latent heat storage (LHS) systems and thermochemical energy storage (TCES)...
