Identifying the ecological and evolutionary mechanisms that determine biological diversity is a central question in ecology. In microbial ecology, phylogenetic diversity is an increasingly common and relevant means of quantifying community diversity, particularly given the challenges in defining unambiguous species units from environmental sequence data.

Several uranium anomalies, with concentrations of U₃0₈ that
average below 0.003 percent and reach maximums of 0.069 percent,
are associated with black, fossiliferous, pyritic parts of the Ordovician
Ledbetter Slate in northern Stevens County, Washington. The most
uraniferous parts of the slate occur in small (average of 5 by 30...
In this thesis I present the results of a comprehensive assessment of the Pacific-North American (PNA) teleconnection pattern in general circulation models (GCMs) and a regional climate model (RCM). The PNA teleconnection pattern is a quasi-stationary wave field over the North Pacific and North America that has long been recognized...
Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...
Early studies on the biosynthesis of the quinoline quinone portion of
streptonigrin, 1, had suggested the intermediacy of novel aromatic amino
acids. In order to test this hypothesis, a series of compounds was synthesized
and tested for potential incorporation. [4-¹⁵N] 4-Aminoanthranilic acid,
4 5 a , [4-² H] 7-aminoquinaldinic acid,...
Illegal Mexican migration to the U.S. appears to have increased substantially
over the past fifteen years. Most illegal Mexican aliens migrate
with the aim of obtaining better employment opportunities and higher
earnings in the U.S. than are available in Mexico. The potential impacts
of this migration on various U.S. interests,...
Sitka alder (Alnus sinuata (Regel) Rydb.) dominates many lodgepole pine (Pinus contorta ssp. latifolia Dougl.) sites following clearcutting in the Montane Spruce zone of the southern interior of British Columbia. The objectives of this study were to examine the effects of the sitka alder-dominated shrub community on the performance of...
