SUMMARY
by its larger competitor. The advantage for the smaller predator was of such magnitude
that it potentially enables a stable coexistence of both predators.
This study contributed new insights on: (1) the species composition and seasonality of
dinoflagellates and ciliates in the North Sea, (2) methodological improvements
concerning microzooplankton grazing experiments, (3) the important role of
dinoflagellates and ciliates as grazers and also as prey for higher trophic levels and (4)
interactive relationships between microzooplankton predators.
