The objectives of this study were: 1) to learn the life history and habits of Medetera aldrichii Wheeler and a Lonchaea sp. in association with the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, in western Oregon and Washington; 2) to determine if the larvae of M. aldrichii were predaceous on the Douglas-fir...
The consumptive water use of six cities in the Willamette
Basin of northwestern Oregon was evaluated for the period 1960-66.
Consumptive use ratios were obtained by analyzing data from monthly
water supply and sewage flow records. The average annual consumptive
use for the six cities was found to be 26...
An enhancement of the therapeutic effect and/or a reduction in
the toxicity have been shown by a variety of antineoplastic compounds
when glucose is added to the treatment schedule. A possible explanation
for this involves a selective change in intracellular pH of the
tumor tissue initiating a greater uptake of...
The relationship of intracellular drug levels and resultant drug activity to intracellular pH (pHi) was studied in the experimental tumors. Glucose (5 g/kg) and/or sodium oxamate (0.1 mmol) were administered to Walker 256 ascites cells and Ehrlich ascites cells, in an attempt to alter pHi as measured by the distribution...
This study was conducted to observe the manner in which three local
public interest organizations participated in a local, environmentallyoriented
decision process. The study period began in December, 1978,
with the passage of a revised solid waste ordinance (Ord. 78-102) for
the City of Corvallis, OR. The main forum for...
The objective of this study was to determine whether visitor
perceptions of ecological impacts at wilderness campsites could be
accurately measured using photographs or written descriptions rather
than actual site evaluations. Photographs and written site descriptions
of 20 campsites were used to measure perceptions of two forms
of campsite impacts...
Pretreatment of male C57BL/6 mice with low doses of the persistent organochlorine
(OC) pesticide, chlordecone (CD), stimulated biliary excretion of exogenous CH up to 3-fold. Increased biliary excretion occurred without changes in hepatic ATP-binding
cassette transporter G8 (ABCG8) of the bile canaliculus or scavenger receptor class B
type I (SR-BI)...
This paper was written as a book chapter on the ecology and biology of sage grouse. Because the book was never fully developed, we chose to publish the information with the OSU Agricultural Experiment Station.
What do you say when you have only a minute to explain to a municipal official why keeping track of the number of bird species found in a park may help make decisions about park management? Talk of significant differences among treatments or testing theory will likely meet with glazed...
The rapid expansion of western juniper into neighboring plant communities during the past 130 years has caused considerable concern because of increased soil erosion, reduced stream
flows; reduced forage production; altered wildlife habitat; changes in plant community composition, structure, and biodiversity; and the replacement of mesic and semi-arid plant communities...
In optically shallow waters, i.e., when the bottom is visible through the water,
a tantalizing variety and level of detail about bottom characteristics are
apparent in aerial imagery (Figure 1a). Some information is relatively easy to
extract from true color, 3-band imagery (e.g., the presence and extent of submerged
vegetation),...
