Soil moisture depletion trends under five plant species growing
on the clear-cuts of the Marys Peak Watershed near Corvallis,
Oregon, were followed during the summers of 1963 and 1964. The
species were Holcus lanatus, Lotus crassifolius var. subglaber,
Gaultheria shallon, Berberis nervosa, and Acer circinatum; and
were dominant plants of...
The Weather Radar Set An/CPS-9 at McCulloch Peak,
Oregon, provided data of changes in radar precipitation
echo patterns in the vicinity of Marys Peak. Echo heights
studied from data collected on 14 March 1963 averaged nearly
the same upwind, directly over Marys Peak, and downwind.
For the data of 28...
A study was undertaken in the Marys Peak watershed with the
following objectives. First, a classification of the major plant communities
was carried out. Second, some of the ecological features
of Acer circinatum that account for its distribution within these
communities were determined. The following plant communities
are described:
Corylus...
Members of the family Simuliidae were studied in a single,
confined drainage system. In addition to determining the occurrence
and distribution of the species present, biological and ecological
observations were made. Specific measurements and observations
were accomplished to determine as much as possible about the habitat
specificity and life cycle...
The objectives of the study were (1) to determine the differences
in ability of seniors and freshmen to apply principles learned
in a clothing selection course to selection of clothing, (2) to determine
retention of concepts learned in the course, (3) to determine if
age, grades, social class, and occupational...
The purpose of this study was to identify the most recent
trends in Clothing and Textiles, to find whether any relationship
existed between them, and whether there was difference of emphasis
between large and small schools.
The information about existing trends in Clothing and Textiles
was collected from literature published...
This study has been concerned with the patterns of vegetative changes which occur during the first five years following logging and burning on Douglas-fir clear cuts. Knowledge of the successional sequence in the coastal forests of western Oregon is of primary importance to those concerned with the management of this...
