Unstable prices have been a chronic problem in the U.S. hog
industry during the past 15 years, and several studies illustrate the
need for price risk avoidance tools for hog producers. One such price
risk management tool is the use of live hog futures markets. This
study explores if Pacific...
Juvenile Chinook salmon (Oncorhynchus tshawytscha) exhibit an array of life history tactics in Oregon's Willamette River Basin, yet we do not know to what extent it is driven by phenotypic plasticity or whether it is predetermined and how conditions in the early rearing environment may affect phenotype expression. We have...
This investigation has as its purpose: (1) to identify present
student personnel practices in evening community college programs,
(2) to identify student personnel practices considered "desirable" or
"undesirable" in evening community college programs, and (3) to
develop student personnel service guidelines for an evening community
college program.

Patterns of settlement of larvae and population dynamics
of juveniles are poorly known for coral reef fishes. During
1987 to 1989, I studied these phenomena in the domino
damselfish (Dascyllus albisella), a species endemic to the
Hawaiian Islands. Larvae settle onto branching coral heads
as new recruits (10-15 mm in...
A sequence of soils derived from tuffaceous rocks was sampled
on the H. J. Andrews Experimental Forest and adjacent U. S. Plywood
land to determine some genetic and stability relationships. The
less than two micron size fraction from each sample was characterized
by x-ray diffraction with respect to crystalline clay...
