Sediment yield increases following timber harvest and road construction
were predicted for four Pacific Northwest experimental
watersheds. Sediment yields were predicted using a handbook developed
by the U.S. Forest Service entitled, "An Approach to Water Resources
Evaluation of Non-Point Silvicultural Sources" (WRENS). Predicted
sediment yield increases varied from 40 to...
We have combined shipboard and Seasat altimeter derived data in an intergrated geological and
geophysical study of the Louisville Ridge; a 3500-km-long seamount chain extending from the Tonga
trench to the Eltanin Fracture Zone. A break in the smooth trend of the ridge at latitude 37.5°S has been
recognized in...
The American Fisheries Society (AFS) recognizes the need for conservative and robust management of Pacific rockfishes because of naturally low population growth, the overfished state of many of the stocks, and complex nature of the mixed-stock fisheries (60-plus species). The AFS recommends that catch information be collected on a species-specific...
The NMDA receptor is an important component of spatial working and reference memory. The receptor is a heterotetramer composed of a family of related subunits. The GluN2B subunit of the NMDA receptor appears to be essential for some forms of memory and is particularly vulnerable to change with age in...
The studies to be reported herein were initiated following a cursory search of the literature concerning the lakes of the State of Oregon. Few substantive lirnnological works were located. More detailed efforts added only a few obscure references. Since change is the basic axium of ecology, there was concern for...
Yellow starthistle (Centaurea solstitialis L.) is a member of the knapweed
(Centaurea L.) complex. It is poor forage for all livestock and causes
“chewing disease,” a nervous disorder, in horses. Yellow starthistle infests
millions of acres in California and the Pacific Northwest. Infestations range
from scattered plants to dense stands...
Increasingly, objectives for forests with moderate- or mixed-severity fire regimes are to restore successionally diverse landscapes that are resistant and resilient to current and future stressors. Maintaining native species and characteristic processes requires this successional diversity, but methods to achieve it are poorly explained in the literature. In the Inland...
These are the proceedings of the third short course in the management of young Douglas-fir and western hemlock conducted by the School of Forestry, Oregon State University, June 15-18, 1970.
The course included one day of lectures and discussion on the campus of Oregon State University, two all-day field trips...
Analyses of long-term records at 35 headwater basins in the United States and Canada indicate that climate change effects on streamflow are not as clear as might be expected, perhaps because of ecosystem processes and human influences. Evapotranspiration was higher than was predicted by temperature in water-surplus ecosystems and lower...
