Calanoid copepod diet was investigated in Oregon coastal waters to determine
the trophic significance of phagotrophic protists as copepod prey within an ecosystem
where the microplankton biomass is typically dominated by large diatoms. Prior to and
during the 1991 upwelling season, clearance rates on phytoplankton and phagotrophic
ciliates were measured...
How certain aspects of the swimming behavior of the copepod Calanus
marshallae vary as a function of different food conditions of Thalassiosira weissflogii
was examined. A two video camera recording and controlled food environment
aquaria system were used to record long-term swimming behavior and to determine 3-
dimensional swimming paths...
