Yeast mannoproteins released during the process of aging wine on the yeast lees have been reported to make important contributions to wine quality. However, few mannoproteins have been identified in wine and their lifespan during aging is unknown. As a first step towards better understanding the contributions of yeast mannoproteins...
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...

• A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees.
• Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...
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...
At first glance, Edgar Rice Burroughs's wildly popular romantic fantasy novel, Tarzan of the Apes (1912), and Charlotte Perkins Gilman's feminist science fiction-utopian novel, Herland (1915), with its dystopian companion, With Her in Ourland (1916), may appear to have little in common. Tarzan celebrates the human connection with wild nature...
Calls for increased farmer involvement in research and extension programs
have been numerous and well supported. One approach to integrate the collective
knowledge and experience of agricultural scientists and farmers is through whole
farm case studies (WFCS). An interdisciplinary team of 34 research and extension
personnel at Oregon and Washington...
In the United States during the last 30 years there has been a shift from extractive natural resource-based economies of the Old West to a New West defined by environmental protection. Over the past century, a growing national support for environmental protection has influenced a lengthening list of national and...
This thesis presents an analysis of seventeen contemporary blockbuster films in which women kill people. The purpose of the analysis is to discover the "frames" with which film producers, directors, scriptwriters and actors portray women in film. The thesis first establishes the model in use in the analysis: Entman's model...

Biogeochemical data from four small watersheds in the Silver Creek study area, southwestern Idaho, provide the basis for: 1. An estimate of chemical and erosional denudation rates (CD and ED), 2. an estimate of plagioclase weathering rate, 3. a rational basis for estimating the rate of nutrient supply to soil...
Application of sewage sludge to soils increases the trace metal
content and the organic content of soils. The complexation of indigenous and added metals with organic constituents must be studied to
evaluate metal availability to plants and animals.
The water soluble organic fractions (WSOF) from an agricultural
soil (W), a...
Experiments were carried out to study the movement of water and
halide anions in perched water tables or saturated zones in the soil
and upper rock mantle of eight different experimental sites located
on low hills near the western border of the Willamette Valley. At each
site the experimental procedure...
Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they
fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling
at a scale functional for management. We used stratified random sampling and generalized linear mixed
models to test hypotheses...

Grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification. Because population performance of these species is also influenced by non-anthropogenic factors, it is important to incorporate all relevant ecological drivers into demographic models. We used design-based sampling and occupancy models to test relationships of environmental...

The global mid-ocean ridge system is the largest magmatic system encompassing over 75% of the Earth’s total volcanism. As magmas ascend through the vertically variable oceanic crust, melts begin to crystallize and diversify and subsequently erupt at the surface. The interpretation of these erupted products observed on the seafloor requires...
