Studies were conducted from 1962 to 1966 to investigate the
effectiveness of several practices in manipulating medusahead
(Taeniatherum asperum (Sim. ) Nevski) infested and/or dominated
ecosystems by releasing competition in favor of perennial grasses.
Several herbicide treatments were evaluated for selective
control of medusahead and cheatgrass (Bromus tectorum L. )...
A study was initiated in 1961 to characterize seral plant
communities in a part of the Cedar Creek drainage in the Tillamook
Burn. Stratification of vegetation into ecological units was a necessary
first step in conifer-animal damage studies supported by the
Oregon State Game Commission.
Reconnaissance information was recorded in...
Animal dietary preferences have been studied by feeding-site
examinations, animal observation, and stomach and esophageal collections.
Analysis of fecal material for undigested plant cuticle is
another means for obtaining the same information.
This study was conducted to: (1) prepare a microscope slide
series depicting the surface features of leaves and...
Increased interest in the field of sensor technology stems from the availability of an inexpensive and robust sensor to detect and quantify the presence of a specific gas. Bulk p-CuO/n-ZnO heterocontact based gas sensors have been shown to exhibit the necessary sensitivity and selectivity characteristics, however, low interfacial CuO/ZnO contact...
Land useable for livestock grazing in the western United States is
diminishing because of spreading municipalities, irrigation developments,
highway construction, recreational demands and withdrawals.
Concurrently, the demand for livestock and livestock products is increasing
because of a rapidly growing population. As a result, production
from the grazing land that remains...
A three-part algorithm is described and tested to provide robust bathymetry maps based solely on long time series observations of surface wave motions. The first phase consists of frequency-dependent characterization of the wave field in which dominant frequencies are estimated by Fourier transform while corresponding wave numbers are derived from...
This study was undertaken to evaluate the dry-weight-rank and
microscopic point methods for determining botanical composition on
perennial ryegrass (Lolium perenne L.) - subclover (Trifolium
subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) -
subclover pasture mixtures throughout a grazing season.
Botanical composition was determined on a monthly basis from...
Forest associations, secondary succession, and relationships
of plant communities to Roosevelt elk were investigated. Stratification
of vegetation into ecological units and an understanding of secondary
succession by habitat-type were a necessary first step in investigations
into browsing of conifers by elk. The study was jointly conducted
by the Oregon State...
This thesis includes four separate studies. The first two studies assessed edge effects in a
700-year-old forest. After 20 years of exposure, epiphyte assemblages on the clearcut edge
were similar to those of the forest interior, but there were some differences in vertical
distribution patterns. Several species restricted to the...
Numerous inquiries about Cascara buckthorn (Rhamnus purshiana De Candolle) are received each year but the School of Forestry at Oregon State College. This paper seeks to give a condensed statement of the history of the Cascara, its use as a medicinal preparation, its silviculture, its value, a description of the...
The present study was undertaken to evaluate the seasonal
botanical composition of two grass pastures, tall fescue (Festuca
arundinacea Schreb.) and perennial ryegrass (Lolium perenne L.).
Botanical composition was determined by four methods: dry-weight-rank,
weight-estimate, hand separation, and the constituent differential,
with cattle and sheep grazing at two intensities.
The...
Recent emphasis on range improvement of sagebrush-bunch-grass
types in Oregon has underscored the need for better understanding
of their importance to deer winter range management. The
objectives of this study were to evaluate the impact of various sagebrush
control practices on the composition, production, and utilization
of deer forage plants...
The purpose of the research was to computerize mathematical
procedures for the analysis of range vegetation and environmental
data. The specific objectives were as follows:
1. to develop and apply computer techniques to the classification
of vegetation in order to provide a phytosociological
framework within which to investigate the ecology...
Diode lasers have many advantages such as small size, high efficiency and small
angular dispersion of the collimated beam. However they also have some problems like
lack of frequency stability. They can not be tuned in wavelength. An external cavity can
solve these problems and decrease the laser linewidth.
To...
Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and
perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum)
pastures in western Oregon during the spring and summer periods
of 1964 and 1965. Esophageal-fistulated Willamette ewes and
Hereford and Hereford-Angus yearling cattle were grazed separately
on each pasture mixture...
Continuously tunable diode laser sources coupled to single-mode fiber are useful sources for fiber Bragg grating (FBG) strain sensors. This paper describes the
development and fabrication of such a device. An introduction is given describing
applications of tunable lasers and some of the different methods of creating a tunable
diode...
In sagebrush ecosystems invasion of annual exotics and expansion of piñon (Pinus monophylla Torr. and Frem.) and juniper
(Juniperus occidentalis Hook., J. osteosperma [Torr.] Little) are altering fire regimes and resulting in large-scale ecosystem
transformations. Management treatments aim to increase resilience to disturbance and enhance resistance to invasive species by...
