A comparative analysis of the importance of mesozooplankton (200–20,000 µm) as grazers of the phytoplanktonic primary production (PP) across a wide spectrum of marine ecosystems revealed mesozooplankton ingestion rates to increase nonlinearly with increasing PP. The slope of the log‐log relationship between ingestion rates and PP was significantly ,1, indicating a decline of relative importance of mesozooplankton grazing with increasing PP. The effect of mesozooplankton on PP (as the percent PP…

Phytoplankton growth, microzooplankton grazing, and carbon cycling in marine systems

Analysis of the global impact of microplanktonic grazers on marine phytoplankton and its implications for remineralization processes in the microbial community shows potential ecosystem differences in micrograzer activity or trophic structure are a large uncertainty for biogeochemical models that seek to predict the microbialcommunity role in carbon cycling from bacterial parameters alone.

Mesozooplankton grazing and primary production: An alternative assessment

In a recent paper in the journal, Calbet (2001) describes the analysis of data on primary production and mesozoo-plankton grazing from a wide variety of marine ecosystems. The somewhat surprising

Zooplankton grazing in the Atlantic Ocean: A latitudinal study

Low grazing impact of mesozooplankton on the microbial communities of the Alboran Sea: a possible case of inhibitory effects by the toxic dinoflagellate Gymnodinium catenatum

The grazing impact of the mesozooplankton community on algae and protozoans was assessed during September 1999 in the Alboran Sea and grazing impacts on stocks showed a weak pressure, which could be in rela- tion to the presence of the toxic dinoflagellate Gymnodinium catenatum in the study area.

Microzooplankton grazing in the oceans: impacts, data variability, knowledge gaps and future directions

Here we review all published data on phytoplankton growth and microzooplankton grazing using the dilution technique to better understand the role of this group of grazers in different regions of the

Should we account for mesozooplankton reproduction and ontogenetic growth in biogeochemical modeling?

Mesozooplankton play a key role in marine ecosystems as they modulate the transfer of energy from phytoplankton to large marine organisms. In addition, they directly influence the oceanic cycles of

Testing the relationship between primary production and Acartia tonsa grazing pressure in an estuarine lagoon

Copepod herbivory pressure in a subtropical lagoon under the hypothesis that HP is higher during periods of low, compared to periods of high productivity is analysed to suggest top-down control on copepods may be one factor constraining fluxes via the herbvory pathway.

During this spring situation in the plume of dilution of the Gironde estuary when small cells dominated, microzooplankton represented the most important grazing community and could potentially control the growth of phytoplankton.

Mesozooplankton grazing on phytoplankton, as inferred from gut pigment contents and gut evacuation rates, was studied in relation to primary production and particulate export flux on 6 cruises in the

Grazing of copepod assemblages in the north-east Atlantic: the importance of the small size fraction

Preliminary estimates of the grazing pressure by copepod assemblages at four stations' 60, 56, 52 and 47°N, along the JGOFS 20°W transect, during June-July support the importance of the small size fraction relative to the other fractions, in terms of numerical abundance and their grazing impact.

Nutrient and temperature control of the contribution of picoplankton to phytoplankton biomass and production

The results of mesocosm nutrient addition experiments during summer in the Mediterranean Sea allowed the dissociation of the effects of temperature from those of nutrients on picophytoplankton production and biomass and validated the magnitude at which picoplankton dominates ($50%) autotrophic biomass and production obtained in the comparative analysis.

Biomass distribution in marine planktonic communities

The patterns described suggest a rather systematic shift from consumer control of primary production and phytoplankton biomass in open ocean to resource control in upwelling and coastal areas.

Small-scale, short-term ex- periments and larger-scale comparative analyses may be inadequate for assessing the strength of trophic interactions, and the potential for community-level responses, not well assessed except at the ecosystem scale, may alternatively dampen or enhance the impacts of Trophic cascades in food webs.

Bacteria-flagellate interactions in the microbial food web of the oligotrophic subtropical North Pacific

It is shown that resources and predators oscillate in importance in regulating open-ocean microbial popula- tions and in such oscillations, the indirect influences of a protistan predatory chain may determine the balance between resource limitation and strong predatory control.
