Seasonal and spatial comparisons of microzooplankton grazing and phytoplankton growth in the Bohai Bay, China

open access: yesFrontiers in Marine Science, 2023
The dilution experiment technique was used in two cruises in July-August (summer) and October-November (autumn) 2020, with a total of 14 stations. The grazing impact of microzooplankton on phytoplankton in the interior of Bohai Bay was comprehensively ...

High tolerance of microzooplankton to ocean acidification in an Arctic coastal plankton community [PDF]

open access: yesBiogeosciences, 2013
Impacts of ocean acidification (OA) on marine biota have been observed in a wide range of marine systems. We used a mesocosm approach to study the response of a high Arctic coastal microzooplankton community during the post-bloom period in Kongsfjorden ...

Grazing impact of microzooplankton upon phytoplankton

open access: yes, 2009
Alterations of freshwater flow regimes and increasing eutrophication can lead to alterations in phytoplankton biomass, composition, and growth in estuaries and adjacent coastal waters.

Microzooplankton communities and their grazing of phytoplankton under artificial upwelling in the oligotrophic ocean

open access: yesFrontiers in Marine Science, 2023
Ocean artificial upwelling has been suggested to boost primary production and increase harvestable resources such as fish. Yet, for this ecosystem-based approach to work, an effective energy transfer up the food web is required.

Seasonal and size-dependent variations in the phytoplankton growth and microzooplankton grazing in the southern South China Sea under the influence of the East Asian monsoon [PDF]

open access: yesBiogeosciences, 2015
To examine seasonal and size-dependent variations in the phytoplankton growth and microzooplankton grazing in oligotrophic tropical waters under the influence of seasonal reversing monsoon, dilution experiments were conducted during the summer of 2009 ...

Grazing on Pfiesteria piscicida by microzooplankton [PDF]

open access: yesAquatic Microbial Ecology, 2000
The potential grazing pressure of natural assemblages of microzooplankton ( 2 d -1 in 6 out of 10 experiments. In previous studies, the maximum instantaneous rate of growth of NTZ was

Microzooplankton growth rates examined across a temperature gradient in the Barents Sea. [PDF]

open access: yesPLoS ONE, 2014
Growth rates (µ) of abundant microzooplankton species were examined in field experiments conducted at ambient sea temperatures (-1.8-9.0°C) in the Barents Sea and adjacent waters (70-78.5°N).

Effects of microzooplankton on the planktonic food web

open access: yes, 2015
Planktonic food web analyses have long focused on interactions between phytoplankton, copepods and fish larvae. However, heterotrophic dinoflagellates and ciliates, here defined as microzooplankton, are known to be efficient consumers of primary ...

Seasonal and spatial comparisons of phytoplankton growth and mortality rates due to microzooplankton grazing in the northern South China Sea [PDF]

open access: yesBiogeosciences, 2013
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 ...

Disentangling niche competition from grazing mortality in phytoplankton dilution experiments. [PDF]

open access: yesPLoS ONE, 2017
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.
