The Hemigrapsus oregonensis population at Coquille Point in
the Yaquina Bay Estuary on the Central Oregon Coast was studied
from April, 1972 through May, 1973. The population was found to be
vertically stratified from the 1 ft level to the 5 ft level. Population
densities were found to be most...
L1R, a myristylated late gene product of vaccinia virus, is essential for formation of infectious intracellular mature virions (IMV). In its absence, only viral particles arrested at an immature stage are detected and no infectious progeny virus are produced. Previous studies have shown that the L1R protein is exclusively associated...
Recreational angling pressure has recently increased in the neritic
reef areas off the central Oregon coast. This study describes
weight-length and age-length relationships as well as ages at sexual
maturity of the black, blue, canary, yelloweye, and yellowtail rockfish
(Sebastes melanops, S. mystinus, S. pinniger, S. ruberrimus, and
S. flavidus,...
Agriculture is now facing the ‘perfect storm’ of climate change, increasing costs of fertilizer and rising food demands from a larger and wealthier human population. These factors point to a global food deficit unless the efficiency and resilience of crop production is increased. The intensification of agriculture has focused on...
Pacific Northwest trawl fishermen spend an estimated $625,000 every year to replace corroded trawl cable. If the Pacific Northwest shrimp fleet is included, the yearly cost greatly exceeds one million dollars. Fishermen could save hundreds of thousands of dollars and increase the net return to the individual fisherman if they...
Practical hydrostatic ocean models are often restricted to statically stable configurations by the use of a convective adjustment. A common way to do this is to assign an infinite boat conductivity to the water at a given level if the water column should become statically unstable. This is implemented in...
