Trapping migrating steelhead trout smolts was done in the spring and early summers of 1991 and 1992 as part of the 1990 Umpqua National Forest Land and Resource Management Plan. Calf Creek was monitored to "validate smolt output estimates" and to "determine if changes in habitat quality are occurring." (Introduction)

Oregon grape growers are sometimes troubled with fruit set problems. There are many types of fruit set disorders, but a recently described one is inflorescence necrosis (IN). Though many studies related to the disorder have been done at OSU and elsewhere, investigation into IN is still in its infancy. Several...
The connection between the fruit-set disorder Inflorescence Necrosis (IN) and high ammonium (NI14+) in affected tissues has led to an investigation of NH4+ assimilation enzymes (principally glutamine synthetase (GS) and glutamate synthase) in grape tissues. Previous work in this department has suggested that toxic levels of NH4+ build up in...
The continuous-time mathematics of a binary-decision making neuromime are presented.
