We present an analysis of the global impact of microplanktonic grazers on marine phytoplankton and its implications for remineralization processes in the microbial community. The data were obtained by an extensive literature search that yielded 788 paired rate estimates of autotrophic growth (µ) and microzooplankton grazing (m) from dilution experiments. From studies in which phytoplankton standing stock was measured in terms of carbon equivalents, we show that the production estimate from…

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

Microzooplankton grazing constrains pathways of carbon export in the subarctic North Pacific

To identify the effect of microzooplankton grazing on phytoplankton abundance and size structure, we quantified phytoplankton growth and herbivorous grazing rates throughout the euphotic zone and

Microzooplankton grazing of phytoplankton in a tropical upwelling region

Grazing estimates were not correlated with microzooplankton biomass, whether or not nauplii were included, suggesting that most of the grazing was done by nano-sized zooplankton.

Changes in phytoplankton and microzooplankton populations during grazing experiments at a Mediterranean coastal site

If growth and mortality of grazers in the dilution series are not considered, microzooplankton grazing impact may be either underestimated, at low phytoplankton growth rates, or overestimated in more productive conditions.

Mesozooplankton biomass and grazing in the Costa Rica Dome: amplifying variability through the plankton food web.

It is proposed that advection of upwelled waters away from the dome center is accompanied by changes in mesozooplankton composition and grazing rates, reflecting small changes within the primary producers.

Microzooplankton: The Trophic Role and Involvement in the Phytoplankton Loss and Bloom-Formation in the Black Sea

For the first time microzooplankton grazing impact on phytoplankton in the Black Sea was investigated in relation to seasonal and spatial variability. In this work we used scientific evidence

Microzooplankton grazing along the Western Antarctic Peninsula

Phytoplankton and bacterial growth and grazing mortality rates along the Western Antarctic Peninsula (WAP), a region of rapid climate change, are reported and valuable information is contributed to studies modeling the flow of carbon through the WAP food web, improving the ability to predict climate-induced changes in the W AP ecosystem.

Seasonal Variability and Drivers of Microzooplankton Grazing and Phytoplankton Growth in a Subtropical Estuary

Rates of microzooplankton grazing and phytoplankton growth are seldom measured with respect to time, yet such estimates may better reflect temporal variability in coastal phytoplankton communities

Revisiting the dilution technique to quantify the role of microzooplankton in DMS(P) cycling: laboratory and field tests

Re-examining the suitability of the dilution technique in studies of dimethylated sulfur cycling in the sea found that bacterial consumption was not affected by dilution, and parallel incubations with and without a specific inhibitor of bacterial DMS metabolism allowed us to estimate the gross DMS production by the whole community and theacterial DMS consumption rate.

MICROZOOPLANKTON GRAZING IN THE ESTUARY OF MUNDAKA, SPAIN, AND ITS IMPACT ON PHYTOPLANKTON DISTRIBUTION ALONG THE SALINITY GRADIENT

In spite of the importance of microzooplankton grazing, this factor alone cannot be responsible for the observed phytoplankton distribution along the salinity gradient, denoting an optimization in the efficiency of energy transport through the pelagic food web.

Grazing impact of micro- and mesozooplankton during a spring situation in coastal waters off the Gironde estuary

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.

Grazing by microzooplankton in the eastern Canadian arctic in summer 1983

The grazing of the high latitude microzooplankton community studied by the dilution method is comparable to that in the lower latitudes.

Protist control of phytoplankton growth in the subtropical north-east Atlantic

The grazing impact of protists on phytoplankton primary production in a highly oligo- trophic area of the subtropical north-east Atlantic, south-east of the Azores, was studied using the dilution method and the net primary production closely oscillated around zero in the chlorophyll a analyses and was positive in the flow-cytometry analyses, suggesting a balanced or slightly autotrophic phy toplankston- protist compartment.

Pigment-specific rates of phytoplankton growth and microzooplankton grazing in the open subarctic Pacific Ocean

Grazing rates were most closely matched with growth rates for small (<10 µm) phytoplankton species; large diatom species seemed to be unaffected by microzooplankton grazing.

Microzooplankton grazing activity in the temperate and sub-tropical NE Atlantic: summer 1996

It is concluded that microzooplankton formed a significant component of the food web in the NE Atlantic and were important controllers of phytoplankton production, particularly in temperate waters, during this investigation period.

Microzooplankton grazing and selectivity of phytoplankton in coastal waters

Microzooplankton grazing activity in the Celtic Sea and Carmarthen Bay in summer 1983 and autumn 1984 was investigated by applying a dilution technique to high-performance liquid chromatographic (HPLC) analysis of photosynthetic pigments in phytoplankton present within natural microplankton communities, indicating a trophic preference by microzooplanks for dinoflagellates, cryptophytes, chlorophytes and prasinophytes.

Phytoplankton blooms are strongly impacted by microzooplankton grazing in coastal North Pacific waters

Phytoplankton growth and microzooplankton grazing were measured in two productive coastal regions of the North Pacific: northern Puget Sound and the coastal Gulf of Alaska to help understand the transfer of primary production to higher trophic levels in these coastal marine food webs.
