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 ...

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.

Microzooplankton grazing in the Eastern Bering Sea in summer
Dilution experiments to estimate microzooplankton grazing on phytoplankton were conducted during the summers of 2008, 2009, and 2010 in the Eastern Bering Sea as part of the BEST-BSIERP integrated ecosystem project. All three summers followed cold springs in the Bering Sea.

Impact of ocean acidification on microzooplankton grazing dynamics
This study examines the potential impacts of projected atmospheric carbon dioxide (pCO2) levels reaching 800 ppm by the end of the century, focusing on ocean acidification effects on marine ecosystems in the coastal areas of Bohai.

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

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 ...
