Lake. Originally Wallowa Lake was an abundant source of fish for
the Indians but the advent of irrigation in the area by the early settlers eliminated the blueback salmon (oncorhynchus...
The purpose of this study was to compare and test the efficiency of the leading kinds of media being used for the isolation and identification

The partitioning of body fluids in the Pacific hagfish was investigated
using several experimental techniques. Direct measurement
of the blood volume was obtained through the simultaneous use
of tagged red blood cells and plasma proteins labeled with Evan's
blue dye. Blood cells obtained from donor animals were incubated
with L-methionin-methyl-C¹⁴...
An automatic, continuous analyzer has been developed which
is suitable for estimating the level of spent sulfite liquors (SSL) in
laboratory samples. The analyzer makes use of a version of the
Pearl-Benson, or nitroso method, and, in its present form, is
useful for samples whose actual SSL solids concentrations are...
An investigation was undertaken to determine if respiratory
changes might occur in conjunction with migrations of the rough-skinned
newt, Taricha granulosa (Skilton) in and out of ponds in the
Willamette Valley. A field study was carried on from December
1964 through October 1965 to investigate certain physical and
chemical parameters...
