Natural populations of kokanee fingerlings were studied in Odell Lake, Oregon from June 1962 to September 1963. Vertical and horizontal distributions were determined in relation to temperature, zooplankton, and light during the summer of 1963. Food habits of the fingerlings were also examined. A mid-water townet was employed for sampling...
"The Siletz River ... is the only short coastal stream in Oregon inhabited by a run of what are generally thought to be native summer steelhead. Hatchery-reared progeny from Siletz River stock have been released into and have become established in two other Oregon coastal streams, the Nestucca and Wilson...
This analysis concerns the life and scientific work of Henry
Augustus Rowland (1848-1901), organizer and the first chairman of
the physics department at The Johns Hopkins University in 1876.
Special materials used in this research included three pieces of
Rowland's experimental apparatus which are extant in the Smithsonian
Institution Division...
The Nearctic species of the genus Sympherobius
Banks are revised. Seventeen species are recorded from
the region. Two new species, S. constrictus and S.
quadricuspis are described from California and Arizona
respectively. Four new specific synonyms are proposed
(junior synonym(s) first): S. brunneus Nakahara and S.
stangei Nakahara = S....
Currently little is known about the mechanisms and locations of
lymphocyte development in teleosts. In this study several aspects of the
underlying factors which govern B lymphocyte development in trout
were investigated which included: the isolation and characterization of
immunoglobulin heavy chain (IgH) genes, the recombination activating
genes 1 and...
This paper discusses the theoretical design parameters of
photographic data recording systems associated with atmospheric
research radar. Practical considerations modify these theoretical
results. The design of a recording system employed on the Range
Height Indicator (RHI) scope of the weather Radar Set AN/CPS-9
atop McCulloch Peak, Oregon, illustrates the optimization...
