Plagiobothrys hirtus is Oregon’s top priority for endangered plant species recovery, and the wetlands of Douglas County provide the only habitat for this plant in the world. The goal is to downlist this species from endangered to threatened, and in order to do that, existing populations must be protected, and...
Marine bacteria from the SAR11 clade (class Alphaproteobacteria), specifically strains
HTCC1062 and HTCC7211, were characterized according to a polyphasic taxonomic approach.
Maximum cell densities and growth rates at various temperatures, salinities, and pH’s were
analyzed. Strains HTCC1062 and HTCC7211 were observed as having different growth
optimums. On the basis of...
The poster was presented at the poster session of the 2nd annual Water Research Symposium at Oregon State University (formerly called Water Day) on 5/18/2012.
Lentisphaera araneosa is a marine microorganism, and its production of expolymer plays an important role in marine ecosystem. The exopolymer production in L. araneosa is studied by measuring the growth of bacteria (in cells/mL) and the viscosity of the medium (in centistokes) under different treatments. The treatment without serine and...
Occlusive thrombi that cause cardiovascular diseases form on the walls of blood vessels and propagate across the lumen under pressure gradient-driven flow, impaired antithrombotic, and enhanced prothrombotic conditions. Development of a well controlled and validated ex vivo model that can mimic these pathological conditions would provide a useful tool for...
The Indo-Pacific Red Lionfish (P.volitans) has invaded coral reefs in the Western Atlantic Ocean and Caribbean. This abundant invader has the potential to negatively affect native species through both competition and predation. A native species that may be particularly vulnerable to this invasion is the Nassau grouper (E. striatus) because...
The toxicity of a group of oxygenated polycyclic aromatic hydrocarbons (OPAHs) was investigated using embryonic zebrafish. An immediate goal was to determine the relative toxicity of these compounds and to explore the toxicity mechanisms. It is thought that some OPAHs cause toxicity by binding and activating the aryl hydrocarbon receptor...
