Oregon College of Education (OCE) is a small, liberal arts college with a special emphasis on the preparation of teachers. Its student population is predominantly from Oregon's Willamette Valley area. OCE developed specific objectives for its teacher education program and the purpose of this study was to determine whether the...
A population of Columbian white-tailed deer (CWTD) was studied on a
refuge (790 ha) in southwestern Washington during 1972-77. Quality of
habitat was considered good for these deer and total population size remained
between 164-230 as determined by mark-recapture methods during
November. Population size declined significantly between the winters of...
This study examined the role perceptions of trustees
in the locally controlled Oregon community college system
and the state controlled Washington community college
system. Authorities in the literature were consulted to
define the "ideal trustee role" and the study determined
which governance system was most effective in fostering
this "ideal...
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. )...
Ninety-one species of birds were surveyed in grass/forb, early and late shrub/sapling, pole, and medium sawtimber stages of young-growth Douglas-fir in northwestern California; patterns of bird distribution and abundance were related to habitat conditions and even-age silvicultural treatments. Seven species (band-tailed pigeon, western wood pewee, dusky flycatcher, western bluebird, fox...
A new photosystem-II mutant of the green alga Scenedesmus
obliquus D₃, strain PS-28, has been shown to lack a-tocopherol
(vitamin E). The photosynthetic activity of dark grown samples of
PS-28 is about 20% of the wild-type control. Culturing the mutant
at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic
activity...
