Abstract

Laboratory experiments were carried out to investigate the effect of protozoan, copepod and comb~ned grazing on Phaeocystis biomass.Phaeocystis cf.globosa single cells were offered to 3 different protozoan species, to the calanoid copepod Temora longicornis, as well as to mixtures of both grazer types.The heterotrophic dinoflagellate Oxyrrhis marina and the oligotrich clhate Strombidinopsjs acuminatum ingested Phaeocystis at much higher rates than did the copepod Nevertheless, protozoan growth and ingestion rates were submaximal, indicating Phaeocyst~s to be subopt~mal food.The ohgotrich ciliate Strombidium elegans did not feed on Phaeocystis.In grazing experiments w ~t h mixtures of both predator types, the decline of Phaeocystis single cells could be explained by protozoan grazing alone, implying no grazing by the copepods on Phaeocystis.Instead, copepods ingested the protozoans at high rates.Predation on 0. marina and S. acuminatum by T. longicornis resulted in a reduct~on of the total grazing pressure on Phaeocystis of 21 and 67 % respectively.We conclude that mesozooplankton predation on herbivorous ciliates and heterotrophic dinoflagellates, which consumed Phaeocystis cells, can considerably reduce the overall grazing pressure and may enhance Phaeocystis bloomng.

  • Copepods have been shown to directly contribute to the blooming of the alga Phaeocystis by selectively eating its protozoan predators.

    “For example, copepods have been shown to directly contribute to the blooming of the alga Phaeocystis (Haptophyceae) by selectively eating its protozoan predators [86].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
