A study was conducted during 1959 and 1960 on the
history and productivity of the crayfish, Pacitastacus
leniusculus trowbridgii, in Berry Creek, a small woodland
stream in western Oregon. This included an estimation of
the annual crayfish production, in terms of tissue
elaborated, of a 1500 foot controlled section of...
In recent years the types of engineering data accumulated by many telemetry systems have become so diversified and complex, and
the environment in which these systems operate has become so restricting
that telemetry systems with increased capabilities and decreased
size are becoming a necessity. Advances in integrated circuitry
techniques satisfy...
This analysis is the study of Oregon's wildlife resources from
the period prior to white settlement up to the present time, including
critical projections, based on present trends and expected conditions
for both human and wildlife populations in the state up to the year 2010.
Prior to white settlement Oregon...
An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The
Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride
with aluminum chloride was shown to give one bicyclic chlorine
containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...
