   abstract: The work of myself and colleagues from other agencies have produced
     most of the contemporary information on Snake River fall Chinook salmon.Research
     Interests:The main focus of my work is understanding Snake River fall Chinook
     salmon life history and ecology to support recovery of this listed stock.  Over
     the years research topics have included migratory behavior, habitat use and
     quantification, physiology, and feeding ecology of juvenile fish in the Snake
     and Columbia rivers.  Other research areas have included understanding the effects
     of elevated flows on chum salmon spawning behavior, and investigating recent
     food web changes to lower Snake River reservoirs.
