Plywood panels collected from thirty seven mills located
throughout the Pacific Northwest they were treated with chromated copper
arsenate Type C (CCA-C) or ammoniacal copper zinc arsenate (ACZA) using
modified full cell and full cell processes respectively. Preliminary
tests were performed to determine plywood sample size, replication, and
treating schedule....
The rainbow trout (Oncorhynchus mykiss) model
of chemical carcinogenesis is becoming increasingly
important as a supplement to rodent studies. However,
much of the molecular biology of the carcinogenic
response is still unknown in the trout model. The ras
gene family has been implicated in the tumorigenesis of
both spontaneous and...
The goal of this study was to gather information on the autecology,
reproductive ecology, and population dynamics of Astragalus australis
var. olympicus as a baseline for conservation strategies and to help
explain its restricted range. Approximately four thousand
individuals occurred in four known population centers in the Olympic
Mountains, Olympic...
Two experiments involving interactions between wheat
(Triticum aesitivium L.) cultivars and rust pathogens were
investigated. One experiment evaluated the aggressiveness
(measured by infection efficiency and latent period) of
populations of Puccinia recondita Rob. when inoculated on
the cultivar they were isolated from, their "own" cultivar,
and when inoculated onto other...
