Western juniper (Juniperus occidentalis Hook) is a species of juniper native to arid regions of the Pacific Northwest. The western juniper tree has a number of competitive strategies that, in conjunction with an almost complete removal of fire from the ecosystem, have resulted in a significant expansion of its population...
Subsurface inputs into lotic systems are a primary mechanism for cooling streams with high ambient water temperatures. Objectives of this study include: 1) to determine the effectiveness of Forward Looking Infrared (FLIR) thermal imagery to detect shallow
aquifers, 2) to characterize certain physical, spatial, and temporal characteristics of the fluvial,...
John Wesley Powell worked actively for public land system
reform while a director of geographical and geological surveys in
the West from 1869 to 1894. Although this has won him acclaim as a
conservationist, the basis of Powell's linkage of reform with
scientific work is poorly understood.
A study of...
The Philpott site (35CS1) is located on the north bank of the
Coquille River near Bandon, Oregon. Test excavations at the site were
conducted in 1978 by Oregon State University under the direction of
Richard E. Ross.

during the analysis of...
Surveys of amateur artifact collections in southwest Oregon indicate
that traditional settlement pattern models for this region may be in error.
Based on the distribution of major styles of projectile points, at least
two distinct periods of occupation are definable. The Early period is
tentatively dated between 1000 B.C. and...
This article examines the influence of Emmanuel Levinas’s philosophy on the ethical aspects of the life and work of André Schwarz-Bart. The essay is framed through recent re-interest in Schwarz-Bart’s collaborative works with his wife, Simone, as a bridge between Holocaust and postcolonial studies. The publications, arguments, and key points...
The dynein molecule is a peculiar motor protein recognized for its unique stepping behavior. Sometimes it steps forwards. Other times it steps backwards. It has even been observed to occasionally shuffle by beginning a step with the same domain many times in row. These motions make dynein an interesting object...
This thesis focuses on the economic efficiency of alternative habitat, streamfiow, and land use
allocations within a major drainage of the Pacific Northwest. Specifically, productivity of present habitat
and streamfiow conditions is evaluated with respect to anadromous fish species (chinook salmon and
steelhead trout) in the John Day River Basin,...
This thesis examines a range of generic influences in William Shakespeare's Richard II. By exploring the play's references to conflicting interpretations of history from different generic perspectives, I hope to advance a more nuanced reading of the play's dynamic staging of history. In Chapter One, I suggest that Richard II...
Modern science was produced by a Christian society,
and although science has had an effect on Christianity, it
could not itself remain unaffected. In the second half of
the nineteenth century, the subject of evolution was as
much a religious as a scientific issue. The battle line
was drawn and...
This study determines the optimal allocation of watershed conservation funds in the John Day River Basin, Oregon. Fund managers can use a variety of targeting schemes to allocate their limited resources. Depending on which targeting criteria is used, they may or may not be achieving the maximum environmental benefits per...
For over 30 years, the Implicit Monte Carlo (IMC) method has been used to
solve challenging problems in thermal radiative transfer. These problems are typically optically thick and di ffusive, as a consequence of the high degree of "pseudo-scattering" introduced to model the absorption and reemission of photons from a...
The growing demand for water in the arid regions of the West
increases the need for optimal allocation of water among competing
uses. An efficient allocation of water between instream and out-of-stream
uses has been impeded by institutional constraints and the
scarcity of information regarding instream flow benefits. The
objectives...

Water temperature is an important measure of water quality, as well as a dominant factor affecting aquatic life within the stream environment. Elevated water temperatures can decrease the survival rate of fish in each life stage. Cold water species, such as salmonids, are particularly susceptible to elevated water temperatures. For...
Interactions between sediment bacteria and available phosphate
necessary for algal production in a eutrophic lake were studied.
Twenty percent of the organisms isolated solubilized phosphate forms
such as CaHPO₄, Ca₃(PO₄)₂, FePO₄, Mg₃(PO₄)₂ and Al₂(PO₄)₂.
Solubilization of phosphates occurred under conditions of aerobic
growth.
Upon quantitative analysis, some isolates were capable...
The Chelan Valley is one of several valleys located on the eastern slope of the Cascade Mountains contributing to the leadership of Washington in apple production. Since the nature of the activity in the Chelan Valley is typical of all these producing areas,it was selected as a case study of...
Rising atmospheric [CO₂], cₐ, is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO₂],...
Nearshore hypoxia along the coast of Oregon and Washington is a seasonal phenomenon that has generated concern among scientists studying this temperate upwelling ecosystem. These waters are affected by coastal upwelling-induced hypoxia mainly during late summer and fall, but the effects of low oxygen levels on fish and invertebrate communities,...
The site-specific incorporation of non-canonical amino acids (ncAAs) into proteins is an important tool for understanding biological function. Traditionally, each new ncAA targeted requires a resource-consuming process of generating new ncAA aminoacyl tRNA synthetase/tRNACUA pairs. However, the discovery that some tRNA synthetases are “permissive,” in that they can incorporate multiple...
Automated sound broadcast systems have been used to address a variety of ecological questions, and show great potential as a management tool. Such systems need to be reliable because treatments are often applied in the absence of a human observer and system failure can cause methodological ambiguity. During the breeding...
The Mongolian Steppe is one of the largest remaining grassland ecosystems. Recent studies have reported widespread
decline of vegetation across the steppe and about 70% of this ecosystem is now considered degraded. Among
the scientific community there has been an active debate about whether the observed degradation is related to...
This thesis discusses the African American authors Richard Wright and James Baldwin, and their views regarding how literature should be written. These views are examined as laid out in a selection of each author‟s essays, as well as through an analysis of the characters Bigger Thomas and Rufus Scott in...
There were two viable theories of generation, preformation
and epigenesis, existing in the Seventeenth and
Eighteenth Centuries. Due to their irreconcilable nature,
they were often at loggerheads during this time interval.
The status of these generation theories can be effectively
understood in terms of Thomas Kuhn's conception of preparadigm
science....
Tree-ring characteristics are commonly used to reconstruct climate variables, but divergence from the assumption of a single biophysical control may reduce the accuracy of these reconstructions. Here, we present data from bur oaks (Quercus macrocarpa Michx.) sampled within and beyond the current species bioclimatic envelope to identify the primary environmental...
A genecological approach was used to explore genetic variation in adaptive traits in Pseudoroegneria spicata, a key restoration grass, in the intermountain western United States. Common garden experiments were established at three contrasting sites with seedlings from two maternal parents from each of 114 populations along with five commercial releases...
Recent controversy over whether biodiversity reduces disease risk (dilution effect) has focused on the ecology of Lyme disease, a tick-borne zoonosis. A criticism of the dilution effect is that increasing host species richness might amplify disease risk, assuming that total host abundance, and therefore feeding opportunities for ticks, increase with...
This essay argues that changes in American energy infrastructure from carbon-based power plants to distributed, renewable energy networks precipitate changes in American literary regionalism. Examining recent regional fiction including Jay Tyrell’s Wind Army, Paolo Bacigalupi’s “The Tamarisk Hunter,” and Richard Powers’s The Echo Maker, I argue that stories of climate-change...
We examine the 0–100 Ma paleoceanographic record retained in pelagic clay from the South Pacific Gyre (SPG) by analyzing 47 major, trace, and rare earth elements in bulk sediment in 206 samples from seven sites drilled during Integrated Ocean Drilling Program Expedition 329. We use multivariate statistical analyses (Q-mode factor analysis...
Dating pelagic clay can be a challenge due to its slow sedimentation rate, post-depositional alteration, and lack of biogenic deposition. Co-based dating techniques have the potential to create age models in pelagic clay under the assumption that the flux of non-detrital Co to the seafloor is spatially and temporally constant,...
AIM: Species that breed sympatrically often occupy different foraging niches to mitigate competition for prey. When resource availability declines at the end of the breeding season, some animals migrate to regions with more favourable environmental conditions. When these life-history traits combine, foraging habitat preferences may continue to influence migration patterns...
Climatic effects in the ocean at the community level are poorly described, yet accurate predictions about ecosystem responses to changing environmental conditions rely on understanding biotic responses in a food-web context to support knowledge about direct biotic responses to the physical environment. Here we conduct time-series analyses with multivariate autoregressive...
Urban landscape water use is increasingly a focus of water conservation efforts. This is especially true in the arid and semi-arid regions of the western United States where increased demand, environmental concerns, and extended periods of drought have created chronic water shortages. However, until recently, little attention has been paid...

There is a lack of consensus regarding the roles of sulfide saturation versus volatile degassing on the partitioning of Cu and Ag during differentiation and eruption of convergent margin magmas. Because of their oxidized character, volatile-rich magmas from the Eastern Manus Back-arc Basin (EMBB) only reach sulfide saturation following magnetite-driven...
To determine whether shading increases drought-induced
root mortality by changing the chemical
composition of roots, I conducted an experiment in which
high and low light treatments in combination with high
and low soil moisture treatments were applied to
seedlings of Douglas-fir (Pseudotsuqa menziesii Mirb.
Franco). Because synthesis of suberin (a...

Retaining agricultural land was a significant concern of Oregon legislatures throughout the l960s and 1970s. Willamette Valley counties primarily use a minimum lot area standard to retain land for agricultural use. Lot area standards used in portions of Yamhill and Clackamas Counties play a conservative force in each county's land...
Polyphenolic compounds found in foods such as fruits, vegetables, legumes, nuts and grains, are an integral part of the human diet. Within polyphenols, proanthocyanidins are referred to as condensed tannins and encompass procyanidins, propelargonidins and prodelphinidins. Among these, procyanidins are the largest group. Recent interest in these compounds is related...
Delta-sigma modulators are currently a very popular technique for making high-resolution
analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).
These oversampled data converters have several advantages over conventional Nyquist-rate
converters, including an insensitivity to many analog component imperfections, a
simpler antialiasing filter and reduced accuracy requirements in the sample and hold....
In 2008, the “Great Recession” gained its momentum and quickly grew into a global crisis that led to massive gross domestic product declines and job losses in countries around the world. Relative to prior economic downturns, young adults were greatly affected by the Great Recession. This likely placed a premium...
Delta-sigma modulators are currently a very popular technique for making high-resolution
analog-to-digital and digital-to-analog converters (ADCs and DACs). Most
delta-sigma modulators in production today employ single-bit quantization because a 1-bit DAC is inherently linear, whereas a multi-bit DAC is not. Were it not for this drawback,
the use of multi-bit...
This thesis was to develop a bone artifact typology for the Oregon coast.
