Microzooplankton production in the oceans [PDF]
Abstract A literature synthesis of phytoplankton growth (μ) and grazing (m) rate estimates from dilution experiments reveals that microzooplankton account for most phytoplankton mortality in the oceans, averaging 60–75% of daily phytoplankton production (PP) across a spectrum of open-ocean and coastal systems. For reasonable estimates of

The Possession of Coccoliths Fails to Deter Microzooplankton Grazers [PDF]
Phytoplankton play a central role in the regulation of global carbon and nutrient cycles, forming the basis of the marine food webs. A group of biogeochemically important phytoplankton, the coccolithophores, produce calcium carbonate scales that have ...

Biogeochemical fluxes through microzooplankton
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

Microzooplankton grazing in the gulf of california
Microzooplankton (organisms < 200 μm) grazing rates were determined using the dilution technique at nine stations in the central region of the Gulf of California and one in the sill of the Guaymas Basin, during spring, summer, and autumn 1995.

ECOLOGY AND DIVERSITY OF MARINE MICROZOOPLANKTON [PDF]
Protists are a taxonomic group of organisms world wild distributed with high abundance and biodiversity; their countless forms, sizes, and trophic activities constitute a continuum of species ranging from bacterial-sized cells for the smallest known species of chlorophytes to meters in length for the largest colonies of radiolaria.

Grazing impact of microzooplankton upon phytoplankton [PDF]
Alterations of freshwater flow regimes and increasing eutrophication can lead to alterations in phytoplankton biomass, composition, and growth in estuaries and adjacent coastal waters. Since phytoplankton is the first trophic level of most aquatic foodwebs, these changes can be propagated to other biological compartments, eventually impacting water ...

Disentangling niche competition from grazing mortality in phytoplankton dilution experiments. [PDF]
The dilution method is the principal tool used to infer in situ microzooplankton grazing rates. However, grazing is the only mortality process considered in the theoretical model underlying the interpretation of dilution method experiments.

Seasonal and spatial comparisons of phytoplankton growth and mortality rates due to microzooplankton grazing in the northern South China Sea [PDF]
We conducted a comprehensive investigation on the microzooplankton herbivory effect on phytoplankton in the northern South China Sea (SCS) using the seawater dilution technique at surface and deep chlorophyll maximum (DCM) layers on two cruises (July ...
