Uptake of [14C]glycine by various size fractions of natural plankton communities was measured to determine if phytoplankton can compete effectively with other members of the plankton community for the free amino acids in seawater. The simultaneous occurrence of glycine uptake, plant pigments, and photosynthetic activity in the same size fractions,...
Urbanites who own forest land belong to a larger category of owners often referred to as small woodland owners. As a group, small woodland owners have been the subject of much investigation. Little research, however, has focused specifically on urban-dwelling owners who, as defined by the Census Bureau, live in...
The annual growth rate for the Corvallis-Benton County
area has traditionally been higher than the growth rate for the
State of Oregon. Corvallis is considered to be one of the most
densely settled communities in the state. Since 1972, Corvallis
has experienced a drastic decline in the number of housing...
Sulfur-coated urea (SCU), a slow release nitrogen fertilizer,
may be economically competitive with conventional fertilizers, but
little is known of the mechanism of urea release from SCU and the
environmental factors which affect the urea release rate. Objectives
of this thesis were: (1) to determine factors which affect the rate...

In part one, levels of dehydrated alfalfa meal greater than 60% of the diet significantly (P < 0.01) reduced the growth of rats fed isocaloric diets. Purified cellulose fed to provide the same amount of acid detergent fiber as contributed by the alfalfa did not affect growth. Feed intake was...
Tests were carried on in growth chambers and in the field to
determine if the harvest of daylength-sensitive long-day cereals
grown during the winter in Arizona could be hastened 30 days by the
use of night interruption.
Two durum lines which were near-isogenic for sensitivity to
daylength were used throughout...
The steadily increasing costs of raw materials, of the treated products, and of their replacement in service, as well as the steadily shrinking supply of preferred species, prompted a forum at Oregon State University on May 15, 1973 "to encourage the use of western hemlock and western fuss for poles...

students....
The purpose of this study was to identify the values
and attitudes of a group of freshman female students and
their parents and to determine if value and attitude differences
existed between these two groups. Therefore, of
equal importance in the study was the quantification of
intergenerational differences.
The subjects...

Tree diameter, understory plant cover, seedling density, elevation, aspect, and slope steepness are recorded for 51 forest stands dominated by Tsuga mertensiana (Bong.) Carr. along the eastern portion of the central Oregon Cascades. Species dominance based on prominence values for
trees and percent cover for shrubs and herbs are correlated...
"Control of competing vegetation during establishment is one of the key links in the chain of events leading to a new plantation and, ultimately, a productive forest resource. Experience has repeatedly shown that, without adequate site preparation, reforestation efforts almost inevitably will fail. Vegetation control during the establishment period by...
This bibliography represents selected literature pertinent to interaction studies of vegetation-seedling competition in reforestation; it is not a complete review of the scientific literature.
The vegetative communities in the subalpine meadows of Hunts
