Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
The prevailing image of the Northwest at the
beginning of the nineteenth century, as portrayed on maps
published at the time, was based more on myth and wishful
thinking than on geographic fact. During the next fifty years
these myths were exploded as exploration of this previously
unknown territory progressed,...
This project explored one set of tools and procedures that
appeared to have the potential to make the handling of the spatial
data necessary for resource management more efficient and
effective. This project used data from the Nature Conservancy's
Lawrence Memorial Grassland Preserve and was designed to explore
a low...
The virus-encoded proteins of tobacco etch virus (TEV), a plant potyvirus, arise by proteolytic processing of
a large polyprotein precursor. The TEV genome codes for two proteinases, a 49-kilodalton proteinase and
helper component proteinase (HC-Pro), which cleave the polyprotein at specific sites. The only known cleavage
event catalyzed by HC-Pro...
We report paleointensity results of the Earth's
magnetic field from n Late Pleistocene lava flow
(Louchadiere, Central France), which recorded an intermediate
geomagnetic field direction (5 sites, mean declination=
114.1°, inclination=58.2°, k=130, α95=6.7°). New K-Ar
age determinations confirm that this flow is contemporaneous
with the Laschamp and Olby flows, and...
High concentrations of the fumigant methylisothiocyanate (MITC) will effectively control decay fungi in large wood structures, but the fungitoxicity of low MITC concentrations and the influence of wood moisture content (MC) on its performance are not well understood. The MC of Douglas-fir heartwood greatly influenced the susceptibility of the decay...
