Microzooplankton ingest a significant fraction of primary production in the ocean and thus remineralize nutrients and stimulate regenerated primary production. We synthesized observations on microzooplankton carbon‐specific grazing rate, partitioning of grazed material, respiration rate, microzooplankton biomass, microzooplankton‐mediated phytoplankton mortality rate, and phytoplankton growth rate. We used these observations to parameterize and evaluate the microzooplankton compartment in a…

What controls microzooplankton biomass and herbivory rate across marginal seas of China?

Microzooplankton are the primary herbivores and nutrient regenerators in the marine food web, but their importance is often underestimated, and the quantitative relationships between environmental…

The Role of Zooplankton Grazing and Nutrient Recycling for Global Ocean Biogeochemistry and Phytoplankton Phenology

Zooplankton plays a notable role in ocean biogeochemical cycles. However, it is often simulated as one generic group and top closure term in ocean biogeochemical models. This study presents the…

Zooplankton and the Ocean Carbon Cycle.

This work explores current knowledge of the processing of zooplankton food ingestion by absorption, egestion, respiration, excretion, and growth (production) processes and examines the relative importance, combined magnitude, and efficiency of export mechanisms.

Modeling the spring blooms of ciliates in a deep lake

This study compares the simulation results from several alternative models considering different formulations of ciliate growth in a hydrodynamically driven 1D nutrient-phytoplankton–multiple zooplanka model, with long-term datasets from the deep, monomictic Lake Constance, and suggests that employing a simple density-dependent mortality term offers a pragmatic solution for the challenge of including the microzooplankton in ecosystem models.

Does warming enhance the effect of microzooplankton grazing on marine phytoplankton in the ocean?

Warming may enhance phytoplankton losses to microzooplankton herbivory in eutrophic but not in oligotrophic waters, and the GAM analysis provides important insights into underlying system relationships and reasons why community-level responses in natural systems may depart from theory.

Microzooplankton functional responses in the lab and in the field

The collected data contained information on microzooplankton functional response, and how some external factors affect them, and the sum of all data sets differs from the present data compilations which provides harmonized units and temperature adjusted metabolic.

Assessment and Constraint of Mesozooplankton in CMIP6 Earth System Models

Although zooplankton play a substantial role in the biological carbon pump and serve as a crucial link between primary producers and higher trophic level consumers, the skillful representation of…

Microzooplankton Communities in a Changing Ocean: A Risk Assessment

Microzooplankton communities are fundamental components of marine food webs and have the potential to impact the functioning of carbon pumps. The identification of common responses of…

Role of zooplankton dynamics for Southern Ocean phytoplankton biomass and global biogeochemical cycles

Global ocean biogeochemistry models currently employed in climate change projections use highly simplified representations of pelagic food webs. These food webs do not necessarily include critical…

Phytoplankton competition during the spring bloom in four Plankton Functional Type Models

Differences in the mechanisms of phytoplankton competition during the spring bloom in four state-of-the-art plankton functional type (PFT) models suggest that the response of marine ecosystems to climate change could significantly differ among models, even if the present-day ecosystem is reproduced to a similar degree of confidence.

Biogeochemical fluxes through mesozooplankton

Mesozooplankton are significant consumers of phytoplankton, and have a significant impact on the oceanic biogeochemical cycles of carbon and other elements. Their contribution to vertical particle…

Mesozooplankton grazing effect on primary production: A global comparative analysis in marine ecosystems

Contrary to the common assumption, the size barrier imposed by dominant picoautotrophs does not always result in a lower grazing pressure in unproductive communities, and suggests that alternative food sources (e.g., protozoans) must represent an important component of mesozooplankton diet in un productive ecosystems.

Heterotrophic dinoflagellates: a significant component of microzooplankton biomass and major grazers of diatoms in the sea

Evidence is presented that phagotrophic dinoflagellates appear able to grow on diverse prey taxa and to persist at low food abundance, and that these protists may be able to survive during non-bloom conditions and then grow up when phytoplankton blooms occur.

An ecosystem model of the global ocean including Fe, Si, P colimitations

A nine-component ecosystem model embedded in the Hamburg model of the oceanic carbon cycle (HAMOCC5) is embedded, able to reproduce the main characteristics of two of the three main HNLC areas, i.e., the Southern Ocean and the equatorial Pacific.

Zooplankton grazing and growth: Scaling within the 2‐2,‐μm body size range

The size dependency of grazing and growth rates in zooplankton, data collected from laboratory studies in the literature, covering both limnic and marinc organisms, found significant differences between groups, but the entire set of observations could not be fitted by an overall regression.

Biogenic carbon cycling in the upper ocean: effects of microbial respiration.

It is shown that bacterial respiration generally accounts for most community respiration, which implies that a larger fraction of assimilated carbon is respired at low than at high latitudes, so a greater proportion of production can be exported in polar than in tropical regions.

Particle production by planktonic ciliates1

The similarity in size of microplanktonic algae and ciliate fecal aggregates makes the Coulter Counter inappropriate for use in determining clearance or ingestion rates in ciliate feeding experiments unless egestion rates can be estimated.
