Forest growth and yield models are critical to supporting decision making in forestry, but often lack considerations for wood properties. The feasibility of simulating wood properties in the context of a Douglas-fir individual tree growth and yield model was evaluated. This assessment explored the effect of predicted sapwood width, stem...
Limnology is undergoing a transition to high-throughput -omic analysis of freshwater
bacterial communities. An important first step in making the transition is to
characterize several genomes that can be used as references to guide metagenome
assembly and analysis. Here I characterize four new freshwater cyanobacterial
genomes, a pair of lake...
Studies were conducted to investigate the metabolism of
selenium (Se) , and the influences of Se on the metabolism of cadmium (Cd) and inorganic mercury (Hg) in rats, and in ram semen in
vitro. Se-deficient (-Se) or Se-adequate (+Se) rats were injected intraperitoneally with either ¹⁰⁹CdCl₂ (5 μCi/rat) or ²⁰³HgN0₃...
Two key challenges emerge when initiating individual-tree growth models for bare ground or very young plantations. Both involve the need for a list of individual trees with known or predicted size and known expansion factor (number of trees per unit of area represented by each tree). In the case of...
Thermal cracking of asphalt concrete pavements is responsible for millions
of dollars in annual maintenance and rehabilitation costs in the United States and
Canada. Thermal cracking is typically associated with low temperatures in
northern climates and at high elevations. However, another form of thermal
cracking, known as thermal fatigue cracking,...
We examine the interactions and feedbacks between bathymetry, waves, currents, and
sediment transport. The first two pro jects focus on the use of remote sensing techniques
to expand our knowledge of the nearshore. Due to the plethora of snap-shot data that is
available from satellites and their distribution via Google...
The Hippo signaling pathway is an evolutionarily conserved regulator of cell growth, proliferation, and apoptosis. A key function of the pathway is to regulate the subcellular distribution and activity of Yorkie in Drosophila or Yes-associated protein (YAP) and transcription co-activator with PDZ-binding motif (TAZ) in mammals. The dysregulation of the...
This thesis presents an examination of the nearshore wave bottom boundary layer
under conditions of significant sediment response. Using both field observations and
simple models, the response of the bottom boundary layer to random waves is shown to
have a complex behavior. First, the linearized wave bottom boundary layer governing...
Mountain Quail (Oreortyx pictus) populations have declined in many areas of the western Great Basin during the past century. Yet the life history of this species is little known. From 1997 to 2000, I studied radio-marked Mountain Quail in Hell's Canyon in northeastern Oregon, in the Cascade Mountains of southwestern...
