Concerns over the possibility of exotic pest
introductions from eastern Russia to the West Coast of the United States due to proposed log imports raises the question of the effectiveness of possible mitigation measures. Toxicity of methyl bromide to representative pathogenic fungi was tested by exposing Armillaria ostoyae, Heterobasidion annosum,...
The effect of drying conditions on gas permeability and preservative treatability
was assessed on western hemlock lumber. Although there were no differences in gas
permeability between lumber dried at conventional and high temperatures, there were
differences in preservative penetration. High-temperature drying was associated with
improved penetration of ammoniacal copper zinc...
The air permeability of western hemlock from coastal forests in western Oregon was assessed. Permeability varied widely among trees, as well as by position within individual trees. Permeability tended to decrease with distance inward from the bark, a trend implying that this species produces a heartwood zone. These variations may...
Large quantities of smaller diameter materials are available in the overstocked forests of eastern Oregon and Washington, but the costs of removing these materials and the long distances from markets sharply reduce the potential of this resource. Failure to thin these forests will sharply increase the likelihood of catastrophic wildfires....
The study compares the differences in verbal responses between
39 Anglo-resident and 32 Anglo-migrant children in the first grade in
selected school districts in Oregon.
The children were tested for I. Q. using the Goodenough Draw-
A-Man test. They were grouped for comparison purposes by age,
sex, and by migrancy...
Strategic planning is a frequently used method for defining appropriate institutional responses to changing internal and external conditions. Numerous efforts have been made to adopt strategic planning styles that were originally developed in manufacturing businesses to the purposes of higher education. Despite theses efforts, community colleges have not yet developed...
Salmonid fish raised in hatcheries often have lower fitness (number of returning adult offspring) than wild fish when both spawn in the wild. Body size at release from hatcheries is positively correlated with survival at sea. So one explanation for reduced fitness is that hatcheries inadvertently select for trait values...
The copepod Tigriopus californicus shows extensive population divergence and is becoming a model for understanding allopatric differentiation and the early stages of speciation. Here, we report a high-quality reference genome for one population (similar to 190 megabases across 12 scaffolds, and similar to 15,500 protein-coding genes). Comparison with other arthropods...
