This dissertation serves as a contribution to the study of the prehistory of the Central Desert region of Baja California, Mexico. Between 2007 and 2011, a trans-peninsular archaeological survey and excavation program―the Central Desert Early Prehistory Project (CDEPP)―was completed for a portion of the Baja California peninsula extending from the...
Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister...
Incorporation of nanoparticles (NPs) into consumer products is on the rise and human exposure to NPs is unavoidable. Currently, there is insufficient data to assess the safety of nanoparticles. I conducted a series of five studies using the zebrafish model to determine which NP components (i.e., core material or surface...
This project examines the landscape of the farming community of Beagle, Oregon
prior to and during the Second World War and the effect on it due to
the construction of Camp White, a World War II training facility. The Beagle
landscape is examined through the prism of current theory that...
"The First North American Root Weevil Workshop was held at the Oregon State University North Willamette Research and Extension Center in Aurora, Oregon, November 1–2, 2001. The participants discussed topics including root weevil biology, detection, and monitoring, as well as the population dynamics and integrated pest management of root weevils...
Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insufficient...
The La Ballena #3 site J69E is a shell midden located on Espiritu Santo Island in Baja California Sur. Archaeological excavations conducted in the summer of 2004 investigated a midden containing lithic and shell artifacts as well as faunal and human remains. Analysis of the debitage and formed lithic tool...
Dynamic multithreaded processors attempt to increase the performance of a single
sequential program by dynamically extracting threads from sources such as loop
iterations. The scheduling of instructions in such a processor plays a vital role in the
amount of thread level parallelism that can be extracted and thus the overall...
In the fall through spring of 2002/03 and 2003/04, the composition of fish and amphibian communities were examined in intermittent streams in the upper Willamette river basin in western Oregon. I recorded standard aquatic habitat variables and water nutrient concentrations (nitrate and phosphate) and correlated them with fish and amphibian...
Plants respond to defoliation in many different and complex ways, depending on their growth habit and form as well as the extent and duration of the defoliation. Tree crowns have been shown to be quite sensitive to disturbances such as defoliation, however quantitative relationships have rarely been developed, making the...
