Abstract: Project consolidated into project 95320I. The availability of macrozooplankton forage for salmon, herring, and their predators varies in space and time because of changes in physical processes in PWS. In the SEA context, the latter is known as the Lake River processes (SEA hypothesis number 2). When macrozooplankton are not available, macrozooplankton consumers are forced to switch prey, thus Predator Prey Relationships (SEA hypothesis number 3) shift in space and time. These shifts represent fundamental changes in the way the PWS ecosystem produces commercial species, i.e., herring and salmon. A better understanding, particularly a quantitative understanding, is a prerequisite to determining protocols for restoration and recovery of these species.

EVOSTC Data Archive: This project measures stable isotopes of carbon and nitrogen in macro-zooplankton and fishes from Prince William Sound and north Gulf of Alaska in order to reveal primary production sources in an their food. Biologic samples are taken at SEA stations located around the Sound. Project consolidated into project 95320I. Published articles
