The broadest goal of the research covered in this thesis was to contribute
to our limited knowledge of high elevation forest soil ecology. Based on the reeds
of funding agencies, specific objectives were to examine 1) how climate-induced
Abies lasiocarpa ([Hook.] Nutt.) forest expansion affects soil nutrient pools, 2) the...
In an era of human-induced climate change, there is increasing interest in encouraging people to reduce their carbon dioxide (carbon) emissions by adopting low-carbon behaviors, or behaviors that reduce a person’s use of fossil fuels. I designed the Campus Carbon Challenge as a research and outreach project to gain a...
Reforestation of Pacific Northwest forest-lands with western hemlock has been hindered by unexplained plantation failures.
The purpose of this thesis is to provide information that will help in determining the cause of seedling damage and mortality. The studies focused on the relationship between xylem water potential, xylem cavitation and the...
Understanding connectivity among exploited populations is critical to their sustainable management and long-term viability. In the marine environment, estimates of connectivity often rely on the use of genetic markers, as dispersal primarily occurs during a planktonic larval phase which is difficult to track using direct methods. In this thesis, we...
Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....
On April 1, 1976, Steve Jobs and Steve Wozniak entered into a partnership agreement to found Apple Computer. In the decade that followed, Apple experienced remarkable growth and success, as Jobs catapulted Apple to the Fortune 500 list of top‐flight companies faster than any other company in history. Under direction...
The emphasis of this work has been in two areas of optical materials - the
crystal-chemical development of new optical frequency converters and the synthesis
and study of new hosts for Cr³⁺ luminescence and lasing.
A simple method has been developed to identify promising frequency-doubling
materials containing triangular oxoanions by...
