Characterization of a virus requires that its physical, biochemical
and biological properties be determined. In this study the
Oregon sockeye salmon virus was characterized. It was isolated
in the fall of 1958 from juvenile sockeye salmon, Oncorhynchus
nerka, being reared at the Oregon Fish Commission's Willamette
River Hatchery.
When inoculated...
The authors varied the number of red alder retained with 300 Douglas-fir per acre on a high-quality site in coastal Oregon. Alder densities of 0, 20, 40, and 80 per acre were tested. The authors' fifth treatment eliminated nitrogen-fixing alder, but substantial nitrogen fertilizer. Treatment 6 had neither thinning nor...

Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...
