English sole (Parophrys vetulus) is a flatfish found in abundance in the Pacific Ocean and is part of the Pacific Northwest's and California's commercial trawl fishery. Stock levels of this fish are at all time highs but there are decreased landings due to low demand and acceptability. With new regulations...
Infrageneric classification in Ribes has previously relied on a few, often
conflicting, morphological markers, such as spines, glands, and inflorescence
morphology. Suggestions that hybridization drives the evolution of the genus have
not been tested using phylogenetic methods. To assess the validity of infrageneric
classifications and the importance of hybridization to...
A high-temperature, high-pressure autoclave has been
adapted for use with a high-field nuclear magnetic
resonance spectrometer. The autoclave has an internal
pressure range of atmospheric pressure to 1.5 kbar and a
temperature range of 273 K to 1900 K. The autoclave is
usable in a high field (8 T) magnet...
In the face of limited resources, how should those resources be allocated? The COVID-19 pandemic highlighted the difficulty of allocating a limited number of vaccines. The Centers for Disease Control and Prevention (CDC) issued standard guidelines based on ethical principles, yet all 50 states in the United States (US) interpreted...
In the United States, the state of housing and the lack thereof has been
declared a national crisis. In response, cities have taken measures to police behaviors
that are associated with what they perceive to be disorder and decay. These behaviors
are also commonly associated with houselessness. Laws that criminalize...
Three sets of blood samples were taken from 532 beef calves of two populations at 24 to 48 h after birth, at an average age of 164 d (at time of vaccination for infectious bovine rhinotracheitis virus or IBRV) and at an average age of 224 d (60 d postvaccination)....
There has been increased concern about radiation dose to the female breasts, with approximately 200,000 new breast cancers being diagnosed each year in the United States. The unprecedented increase in the use of radiologic exams on younger women has also raised some additional concerns about how procedures are performed. The...
The interaction of magma with continental crust at convergent margins is fundamental to
understanding if and how continents grow. Isotopic and elemental data constrain the
progressive stages of development of the magmatic underpinnings of the long-lived
Aucanquilcha Volcanic Cluster (AVC), situated atop the thick continental crust of the
central Andes...
Women today represent a larger part of the American workforce
than ever before. The influx of women into the workplace raises
questions about differences in male and female work-related behaviors
particularly in groups, and decision making. For example, existing
research suggests that men and women have differing strategies in
groups...
Energy development is expanding rapidly across the western US. Negative effects have been documented for some wildlife, but consequences of development are unclear for other taxa, including raptors. We had the opportunity to examine effects of oil and natural gas development on two raptor species of conservation concern, ferruginous hawks...
A greater than 10-fold increase in Canada goose (Branta canadensis) populations over the past several years has resulted in concerns over grazing impacts on grass seed production in the mid-Willamette Valley, Oregon. This study was designed to develop methods to quantify and statistically analyze goose-grazing impacts on seed yields of...
This Thesis explores the possibility of increased export and
