Robert E. Bilby is the manager of the National Marine Fisheries
Services Watershed Processes Program at the Northwest Fisheries
Science
Center in Seattle. . He received a B.S. in zoology from the University
of
Rhode Island and a Ph.D. in aquatic ecology from Cornell University.
Bilby was an aquatic ecologist with Weyerhaeuser Company from
1980 through
1998. He is an affiliate faculty member at the University of
Washington
Center for Streamside Studies and currently serves as President
of the
Western Division of the American Fisheries Society. Bilbys research
has
focused on the response of stream ecosystems and salmon populations
to
human actions. This work has included investigation of the role
of large
wood in streams and the impact of forestry on this material, response
of
stream trophic systems to disturbances, production of sediment
by logging
roads and its effect on stream biota and the effectiveness of
instream
habitat enhancement efforts. Over the last 8 years Bilby has
used stable
isotope analysis to quantify the important contribution that spawning
salmon make to the nutrient capital and productivity of streams.
