We tested closure between in situ radiometric and absorption coefficient measurements by using a nearly backscattering-independent remote-sensing reflectance model that employs the remote-sensing reflectance at three wavelengths. We show that only a small error is introduced into the closure model when the proper functional relationships of f/Q and the backscattering...

This study investigated how lidar-derived vegetation indices, disturbance history from Landsat time series (LTS)
imagery, plot location accuracy, and plot size influenced accuracy of statistical spatial models (nearest-neighbor
imputation maps) of forest vegetation composition and structure. Nearest-neighbor (NN) imputation maps were
developed for 539,000 ha in the central Oregon Cascades,...
Five newly released and two Eastern European winter wheat
cultivars were grown under five different seeding rates (80, 160,
240, 320, 400 seeds per m²). Four of these newly released cultivars
were grown at three different locations which have different environmental
conditions. Data were obtained on grain yield, tiller number...
A laboratory-prepared hot-water extract of yeast is required
for vigorous growth of San Francisco sourdough bacteria (Lactobacillus
sanfrancisco) in pure culture. This requirement was examined
with the goal of determining what is unique about fresh yeast extractives
(commercial extractives exhibit much lower growth promoting
activity), and which components of fresh...
Estuaries are once again emerging as important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. Yaquina Bay, located...

Reported here is an investigation to determine the in vitro and in vivo metabolism
of xanthohumol (XN). XN is the major prenylated flavonoid of the female
inflorescences (cones) of the hop plant (Humulus lupulus). It is also a constituent of
beer, the major dietary source of prenylated flavonoids. Recent studies...

The dominant narrative of U.S. Muslims in higher education is associated with violent rhetoric, anti-American values, and terrorism. After terrorist attacks took place on September 11th, 2001, this narrative expanded to include a depiction of U.S. Muslims as being oppressed and submissive. Hate crimes, discrimination, and Islamophobic attacks towards Muslims...
Studies were conducted in the vicinity of Mount Tolman
on the Colville Indian Reservation in eastern Washington in
order to identify vegetation habitat types of the area.
After field studies were completed, Daubenmire's keys to
habitat types of eastern Washington (1968, 1970) were used
to determine habitat types of the...
Empirical algorithms are developed using high-quality GO-SHIP hydrographic measurements of commonly measured parameters (temperature, salinity, pressure, nitrate, and oxygen) that estimate pH in the Pacific sector of the Southern Ocean. The coefficients of determination, R² , are 0.98 for pH from nitrate (pH^N) and 0.97 for pH from oxygen (pH^Ox)...

The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
In their modern context questions of heredity have come to be
closely aligned with theories of evolution because all such theories
require the presence of heritable variation. Thus the need for an
understanding of a source of variation and a mechanism for its inheritance
became very apparent with the general...

Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire...
Like many areas around the globe experiencing ever-growing demand for diminishing natural resources, the south-central region of Texas is facing a wicked problem in water resource planning and sustainability. This Region includes San Antonio, the seventh largest city in the U.S. With a projected population increase over one million residents...
A five year longitudinal study was begun in 1976 to find a
solution to the problem of early primary children who fail in school
and then adopt the failure syndrome. The study was conducted in four
elementary schools in Oregon which had distinctly different
socio-economic populations.
The tests used for...
Thesis summarizes interviews with growers residing within the Groundwater Management Area (GWMA) in the Southern Willamette Valley of Oregon. Informal and semi-structured interviews were used to identify perceived impediments and incentives perceived by local farmers in following best management practices related to water quality. Results from the interviews were coded...
In an era of political polarization, the possibility of the legalization of recreational marijuana has become a popular topic of controversy. While a few states have passed general legislation, the vast majority still prohibit recreational use. In the interest of understanding why there are so many differences between the states,...

As the elderly population increases, more family, friends, and paid service providers assist them with consumption activities in a group that the authors conceptualize as the elderly consumption ensemble (ECE). Interviews with members of eight ECEs demonstrate consumption in advanced age as a group phenomenon rather than an individual one,...

yet, we have been unable to find a network in Oregon or nationally to report other
stranded marine animals, namely fish, cephalopods, and...
New teaching techniques are the products of a wide

north slopes. Juniper moisture stress was found...
Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease where paralysis of the body is the result of motor neuron function loss. A potential cause of ALS is the loss of zinc from Superoxide Dismutase (SOD). SOD’s cellular responsibility is to enzymatically react with the superoxide anion forming oxygen and the...
