Studies to facilitate reintroduction of golden paintbrush (Castilleja levisecta) to the Willamette Valley, Oregon

Creator:: Lawrence, Beth A.
Abstract:: Golden paintbrush (Castilleja levisecta Greenman) historically inhabited the prairies of the Willamette Valley, Oregon. However, this Pacific Northwest endemic is currently restricted to eleven sites in the Puget Trough of Washington and British Columbia. Recovery criteria call for the establishment of new populations throughout the species historic range, including the...

Efficient heuristics for buffer allocation in closed serial production lines

Creator:: Vergara Arteaga, Hector A.
Abstract:: The optimal allocation of buffers in serial production systems is one of the oldest and most researched problems in Industrial Engineering. In general, there are three main approaches to the buffer allocation problem when the objective is to maximize throughput. The first is basically a systematic trial and error procedure...

Three-dimensional motion of the center of mass and energetic cost across a variety of walking speeds : a comparison between adults with and without Down syndrome

Creator:: Agiovlasitis, Stamatis
Abstract:: It has been previously suggested that the walking pattern of individuals with Down syndrome is inefficient. This is thought to result from increased instability, particularly in the medio-lateral direction, due to the characteristic joint laxity and muscle hypotonia of individuals with DS. Therefore, this work was an attempt to gain...

A nested grid model of the Oregon Coastal Transition Zone: Simulations and comparisons with observations during the 2001 upwelling season

Creator:: Springer, S. R., Samelson, Roger M., Allen, John S., Egbert, Gary D., Kurapov, Alexander, Miller, Robert N., and Kindle, J. C.
Abstract:: The Oregon Coastal Transition Zone (OCTZ) extends several hundred kilometers offshore where shelf flows interact with the northern California Current. A primitive-equation numerical ocean model is used to study the upwelling circulation in this region from 1 May to 1 November 2001. This OCTZ model obtains initial and boundary conditions...

Microbial community structure as influenced by season and stand age in a Douglas-fir (Pseudotsuga menziesii) ecosystem

Creator:: Kucera, Jennifer Moore
Abstract:: Forest harvest can have significant impacts on forest ecosystems that may influence the capacity of soils to sequester carbon (C). The microbial community controls decomposition, which is a critical process in partitioning litter- and root-C between CO₂ and storage in semi-permanent soil-C pools. The objectives of this study were to...

Language Differences between Women and Men and the Attribution of Leadership

Creator:: Dunsworth, Sabrina J.
Abstract:: This research addresses the perception of leadership attributes in light of evaluator and target gender. It specifically investigates whether there is a difference in language usage when the evaluator is female versus when the evaluator is male. Two studies were conducted. A pre-test used instrumental development drawing from studies conducted...

Connectivity among straits of the northwest Pacific marginal seas

Creator:: Cho, Yang-Ki, Seo, Gwang-Ho, Choi, Byoung-Ju, Kim, Sangil, Kim, Young-Gyu, Youn, Yong-Hoon, and Dever, Edward P.
Abstract:: The connectivity among straits of the northwest Pacific marginal seas is investigated with a primitive-equation ocean circulation model simulated for 10 years from 1994 to 2003. Over the simulation interval the temporal and spatial means and variations of the model sea surface temperature are comparable to those of the satellite...

Modeling of ecosystem processes on the Oregon shelf during the 2001 summer upwelling

Creator:: Spitz, Yvette, Allen, John S., and Gan, J.
Abstract:: Three-dimensional ecosystem response to wind forcing on the continental shelf off Oregon is studied using a five-component nitrogen-based ecosystem model coupled to a high-resolution circulation model. We investigate, in particular, the influence of timedependent winds and alongshore variations in shelf topography for summer 2001 during the time period of the...

Bioenergetics individual based model explorations of juvenile coho salmon growth during their first summer on the Oregon shelf

Creator:: Reser, Brendan Alexander
Abstract:: Salmon survival and eventual recruitment success have long been thought to be determined within the first summer following ocean migration. Juvenile growth during this period is largely influenced by ocean conditions such as temperature, prey availability, abundance, and quality. Shifts in these conditions due to climatic perturbations are particularly prevalent...

Gene flow and the relationship of Plethodon stormi and P. elongatus assessed with 11 novel microsatellite loci

Creator:: DeGross, Douglas James
Abstract:: Plethodontid salamanders are model organisms for studying evolutionary questions of gene flow, restricted ranges, and speciation. Plethodon, a diverse genus within Plethodontidae, is widely distributed in eastern and western North America. Much research has been based in the eastern United States where diversity of these salamanders is high. Because of...
