Physical, chemical and bacterial water quality parameters of
the upper Wallowa River were sampled periodically between July 2,
1978 and June 9, 1979 at nine stream and lake sampling sites. Water
upstream from Wallowa Lake was typified by low nutrient concentrations
( generally below detectable limits except for nitrates), low....
A classification of stationary liquids by infrared spectroscopy to evaluate the polarity was made using the solvent effect technique. The infrared C-Cl absorption frequency shift was measured for solutions of 1-chlorohexane dissolved in each stationary phase. These frequency shifts were correlated to the relative retention times of 1-octene/n-octane, trans-2-octene/n-octane and...
Data from the coho salmon migration were examined from three streams of the Alsea Watershed Study, conducted on tributaries to Drift Creek, Oregon, from 1959 through 1973.

Thais (Nucella) emarginata is a common predatory gastropod of the
rocky intertidal system of western North America. It is usually found at
low tide on top of its sedentary prey, barnacles and mussels. Thais
is also highly polymorphic for shell color, and breeding of isolated
females has shown that the...
The teliospore of Tilletia caries germinates to produce a promycelium
with a whorl of primary sporidia at its tip. The time between
emergence of the promycelium and the development of primary sporidia
averaged 2.3 h. Fusion between compatible sporidia occurred within
an additional 3.8 h. Primary sporidia appeared to be...
Observations of wind speed and direction, air and sea temperature,
and solar radiation were obtained from an array of buoys in
JASIN. The observations were analyzed to show spatial and temporal
variability. Spectra of wind speed and air and sea temperature were
computed to illustrate the distribution of variance over...
The relationship between pea enation mosaic virus
(PEMV) and aging pea aphids was studied. Although this
research initially emphasized the relationship between the
decline in the rate of PEMV transmission and the 'concentration
of PEMV within pea aphids, aphid age was found to be
the principle factor influencing transmission. Enzymelinked...
The kraft and kraft-anthraquinone pulping processes were used
for pulping Douglas-fir chips at 170°C, 180°C and 190°C temperatures.
Anthraquinone was added to the pulping liquor at two levels, 0.1%
and 0.2% based on wood, to study its effect on pulp delignification
at the three temperatures. The fluorescent behaviors of kraft...

educational level achieved, age at loss of vision, age at initial...
This research provides information on the distribution of an
unexploited Roosevelt elk population in unaltered habitat in Olympic
National Park. Radio-telemetry was used to document home range and
habitat use by 11 adult cow elk in the Hoh Valley during March 1978,
from 10 June-15 September 1978, and from 1...
Concerns regarding maintaining wheat yield per hectare and extending
the commercial life expectancy of cultivars grown in the Yaqui
Valley of Mexico prompted this investigation. Four genetically diverse
spring wheat cultivars were grown in pure stands and in all possible
combinations at the Northwest Agricultural Research Center at Ciudad
Obregon...
Studies to evaluate resistance in snap beans, Phaseolus vulgaris L. to adult western spotted cucumber beetles, Diabrotica u. undecimpunctata Mann. were conducted in greenhouse cages, field cages, field plots, and in temperature controlled cabinet in the laboratory. Results showed that there were differences in susceptibility to adult feeding injury between...
A survey was conducted of six North American cheese plants to
determine levels of bacteriophages present. Fifty-nine lactic streptococcal
host bacterial strains were utilized in the survey. Phage levels
were generally lower in plants employing modern manufacturing techniques
than in plants employing traditional manufacturing techniques; this
difference was attributed to...
The Reclamation Act of 1902, as amended, is the basic
legislation governing the distribution of water from federal
projects for irrigation purposes. In the three-quarters
of a century since the passage of this Act, technological,
economic, and legal developments have forced a reappraisal
of the original intent of the Reclamation...
Symbiotic associations are established between non-leguminous
(actinorrhizal) nitrogen-fixing flowering plants and two categories
of microorganisms: mycorrhizal fungi and a filamentous actinomycete.
The actinomydete induces nodule formation and produces nitrogenase,
the enzyme responsible for the reduction of atmospheric nitrogen to
a form available to higher plants. The mycorrhizal fungus is found...
The history of fire between 1850 and 1977 in a portion of the
Willamette National Forest in-the central Western Cascades of Oregon was
documented using historical sources. Three types of records were
available: (1) records and writings not primarily concerned with fire
but yielding information about fire in context with...
Laminated root rot of Douglas-fir (Pseudotsuga menziesii (Mirb.)
Franco) caused by the fungus Phellinus weirii (Murr.)Gilbertson was
studied in two successive stands in the Oregon Coast Range. Damage
due to the disease in a 60-year-old second-growth stand was compared
with incidence in the preceding 300-year-old stand on the same site....
Numerical simulation of the January and July global
climate with the OSU two-level atmospheric general circulation
model has generated time series of the global

energy based on 31-day time mean statistics have been
made...
During April 1979 the Oregon Department of Fish and Wildlife participated in a survey of Pacific ocean perch (Sebastes alutus) in cooperation with the National Marine Fisheries Service and Washington Department of Fisheries. The survey occurred off the coasts of Oregon and Washington from Newport, Oregon to Cape Flattery. Planning...
In 1976 the Oregon legislature defeated a bill to assume
primary enforcement responsibility (primacy) of Oregon drinking water
supply systems under the purview of the Safe Drinking Water Act (PL 93-
523), and subsequently reduced state drinking water supervision program
funding by 90%. Since that time Oregon drinking water systems...
Haugh and Box (1977) and Pierce (1977) presented dynamic regression (transfer function) procedures for examining possible interrelationships among more than one time series variable. This report employs these procedures in an empirical analysis of U.S. relative lumber prices, U.S. housing starts, and U.S. log exports to Japan.
The reduction in...
There is a considerable amount of vacant land
zoned for industrial use within the Corvallis Urban Growth
Boundary. A detailed investigation of the area reveals
a total of 632.98 acres of such land. However, when closely
scrutinized, it appears that the total number of acres is
misleading, as only 77.50...
Short-term heating of softwood veneer blocks temporarily softens the wood so that it can be peeled more readily. Heating reduces the depth of lathe checks and the likelihood of splitting and thereby increases the quality and quantity of veneer recovered. The softwood-plywood industry conventionally conditions blocks three ways: steaming blocks...
