The accessions used to create the Snap Bean Diversity Panel were 150 snap bean (Phaseolus vulgaris) cultivars and breeding lines selected from North American and European germplasm to create a population that is representative of the snap bean market class from a historical and geographical viewpoint. This panel was developed...
We developed a multiple linear regression model to
robustly determine aragonite saturation state (Ωarag) from
observations of temperature and oxygen (R² = 0.987, RMS
error 0.053), using data collected in the Pacific Northwest
region in late May 2007. The seasonal evolution of Ωarag near
central Oregon was evaluated by applying...
The fauna of parasitic isopods of the family Bopyridae in Singapore is only poorly known, consisting of only seven species in as many genera in five subfamilies. A new small collection adds four species in as many genera, two of them belonging to a subfamily not previously recorded from Singapore....
From 3 April – 23 September 2009 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius alexandrinus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek,...
Integrated Ocean Drilling Program (IODP) Expedition 316 Sites C0006 and C0007 examined the
deformation front of the Nankai accretionary prism offshore the Kii Peninsula, Japan. In the drilling area,
the frontal thrust shows unusual behavior as compared to other regions of the Nankai Trough. Drilling
results, integrated with observations from...
The effect of cosputtered catalyst on growth and alignment of carbon nanotubes (CNTs) grown by plasma enhanced chemical vapor deposition (PECVD) was investigated. Aligned CNTs were observed using a cosputtered catalytic metal deposited directly on boro-aluminosilicate glass. Catalytic metal alloys were sputtered directly onto the substrate using magnetron sputtering. Deposition...
Empirical evidence indicates that environmental fluctuations have important effects on fisheries production. However, existing analytical solutions of stochastic fisheries models have been produced only under highly simplified economic and biological conditions. The main contribution of this paper is to derive under general conditions a policy function for the management of...
Each review covers the population, abundance and distribution, food and feeding, habits, reproduction, mortality and economics, anthropogenic interactions and mortality. The review was completed in May 1998 while the author was a student intern.
This summary focuses on prey species, population and fishery information. General texts were not included. Population and fisheries interaction studies are not an exhaustive sampling but are only include as a supplement to prey species information. An attempt is made to put emphasis on more recent studies. This work was...
This thesis will look at Paul Jensen while he was an education professor at Western Oregon State College in Monmouth, Oregon, and his role in Alaska Native education while working with the Bureau of Indian Affairs. Dr. Jensen's work coincided with the last twenty-five years of Bureau of Indian Affairs...
This is a redacted version of a two-week investigation of academic libraries offering "24/7" services within the Greater Western Library Alliance (GWLA). It was undertaken to better inform Oregon State University Libraries (OSUL) administration of the staffing, security and costs associated with providing such a service. OSUL undertook a pilot...
This thesis investigates the reported communication experiences of married women transitioning to motherhood. The study involves a series of focus groups in which new mothers share their communicative experiences, explaining how they are navigating their new roles as mothers while also performing roles as wives, daughters, and workers. Informed primarily...
Background: Short RNAs, and in particular microRNAs, are important regulators of gene
expression both within defined regulatory pathways and at the epigenetic scale. We investigated
the short RNA (sRNA) population (18-24 nt) of the transcriptome of green leaves from the
sequenced Populus trichocarpa using a concatenation strategy in combination with...
A melt pond model is presented that predicts pond size and depth changes, given an
initial ice thickness field and representative surface fluxes. The model is based on the
assumption that as sea ice melts, fresh water builds up in the ice pore space and eventually
saturates the ice. Under...
Colonization of N. densiflorus tissues by P. ramorum is not well understood. The pathogen is able to colonize nearly all tissues of this host but it is unclear how a tree is ultimately killed. Because this is such a destructive invasive pathogen, it is important to investigate its pathogenic strategy....
Two essays are focused on semiparametric econometric methods. The first essay investigates applicability of the smooth back tting estimator (SBE) to statistical analysis of residential energy consumption. The second essay attempts to incorporate additivity restrictions into semiparametric stochastic frontier estimation. The procedure described in the first study is used to...
My thesis explored the effects of environmental variability on population
dynamics and community composition of aquatic insects. Environmental variability in
the form of flow regime in streams can limit the distribution and life-history traits of
aquatic insects. I used tributaries to the McKenzie River in Oregon with dramatically
different flow...
The lingcod (Ophiodon elongatus) is an important groundfish species in both recreational and commercial fisheries of the Northeastern Pacific. It is a large, fast-growing, generalist predator of invertebrates and fishes. In response to concerns that lingcod may limit populations of rockfishes (Sebastes spp.), I compared the diets of 375 adult...
