Hop (Humulus lupulus L. var. lupulus) is a diploid, dioecious plant with an extensive history of cultivation and use in brewing, as a textile, and for its therapeutic properties. Hop is prized for its ability to produce a variety of aromatic and flavor compounds, as well as compounds with anti-microbial...
Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...
Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...
An innovative silver nano-dimple arrays (Ag DAs)-integrated microfluidic device was developed to achieve highly sensitive fluorescence-based nucleic acid detection. The Ag DAs were utilized to produce surface plasmon resonance (SPR) for strong fluorescence enhancement. We systematically investigated the plasmon-enhanced fluorescence by controlling the nanostructure dimension of the Ag DA substrate....
Over the past 42 years clay smoking pipes have been excavated from two U.S. army posts, Fort Hoskins (35BE15) and Fort Yamhill (35PO75) and curated at Oregon State University. These two forts were established in Western Oregon in 1856 and by 1866 both had been decommissioned. Numerous theses have focused...
Measurements for water retention calculations and physical
characterization were made on skeletal and non-skeletal soils in
southwest Oregon. A new bulk density sampler was designed for the
physical characterization of the steep, skeletal soils commonly
encountered in this area. The new sampler and the techniques
required for the measurement and...
Research was conducted at the Starkey Experimental Forest and
Range in northeastern Oregon to determine cattle performance, diet
quality, botanical composition of forage ingested, and production
and utilization among rest-rotation, season-long, and deferred
rotation grazing systems. The grazing season lasted from June 20 to
October 10 of each year. Cows...
Documentation of the side effects of pesticides on
arthropod natural enemies has expanded rapidly since the
1950's as part of an increase in non-target side effects
literature. Most reviews have been based on empirical
analysis of selected literature. The SELCTV database was
developed to make a larger information base accessible...
Factors influencing pesticide susceptibility and
resistance were studied in Psylla pyricola Foerster, and
its mirid predator, Deraeocoris brevis Knight in the
Rogue River Valley, Oregon. Factors studied were at the
biochemical, life history, and population ecology
levels.
Studies on detoxification enzymes showed that
glutathione S-transferase and cytochrome P-450
monooxygenase activities...
