(1996-07-12)This research examined thinning effects on stand structure and species composition in 50- to 120-year-old Douglas-fir forests. Thirty-two paired stands (thinned and unthinned) were measured throughout western Oregon, a ...
-
(2011-01-14)Surface sediment transport is an important geomorphic process which can be significantly altered by management activities in forested ecosystems. Disturbance of the soil surface may result in increased sediment delivery ...
-
(2009-06-15)PURPOSE: The purpose of this research was to quantify the effects of a warm-up with static or dynamic stretching on countermovement jump height, reaction time, muscle onsets for tibialis anterior (TA) and vastus laterali ...
-
(1997-04-29)Three experiments were designed to determine if and how steelhead trout, Oncorhynchus mykiss, may affect chinook salmon, O. tshawytscha, when they are confined together as in a raceway or on a barge. We observed groups ...
-
(American Geophysical Union, 2012-03-17)This paper examines the effect of “stencil width” on surface ocean geostrophic velocity and vorticity estimated from differentiating gridded satellite altimeter sea surface height products. In oceanographic applications, ...

(1996-02-09)Stream-restoration projects are usually designed to improve habitat quality for fishes. These projects manipulate flow patterns, substrate distribution, and amount and placement of large woody debris. Consequently, the ...

(Elsevier, 2012-04-04)While neutral theory and models have stimulated considerable literature, less well investigated is the effect of topology on neutral metacommunity model simulations. We implemented a neutral metacommunity model using t ...
-
(1996-02-02)In order to restore conifers in hardwood dominated riparian forests 25% of the experimental reach forests alongside four streams in western Oregon was clearcut. Clearcutting removed 400 m without residual buffers from ...
-
(1995-10-24)The environment under which fish are maintained as broodstock before reproduction is often stressful; however, the impact of stress on broodstock and gamete quality is not well known. We investigated the effects of str ...
-
(1990-05-23)A trial was conducted May 1 to September 4, 1989 at the Eastern Oregon Agricultural Research Center (EOARC) Burns, OR to examine the effects of strip or continuous grazing management on the diet and performance of ste ...
-
(1993-08-23)This study examined the practice of student teaching and the effects of student teaching upon the development of three secondary Thai language student teachers from Chiangmai Teachers' College in Chiangmai, Thailand fr ...
-
(1998-10-28)It is difficult to treat the heartwood of many wood species with liquid preservatives using conventional liquid processes. Supercritical fluids (SCF) used as carriers of preservatives to impregnate refractory wood spec ...
-
(Society of Wood Science and Technology, 1997-04)The effects of supercritical fluid (SCF) impregnation on physical properties of composites were investigated at various pressures, temperatures, and treatment times with carbon dioxide as the fluid and tebuconazole as a ...
-
(1981-05-04)This study evaluated the impact of using a rubber-tired skidder to keep the landing clear by sorting and decking the logs along the road prior to loading by a self-loading truck. The evaluation was accomplished throug ...
-
(1977-06-10)An experimental formulation of 9 -oxodec-trans-2-enoic acid, the major component of honey bee (Apis mellifera L.) queen pheromone, was tested for its effect on worker foraging behavior in the pollination of sweet cherrie ...
