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 ...

Microzooplankton Communities in a Changing Ocean: A Risk Assessment

open access: yesDiversity, 2021
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 microzooplankton to global change has been challenging due to their ...

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

open access: yesMarine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

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

Low CO2 Sensitivity of Microzooplankton Communities in the Gullmar Fjord, Skagerrak: Evidence from a Long-Term Mesocosm Study. [PDF]

open access: yesPLoS ONE, 2016
Ocean acidification is considered as a crucial stressor for marine communities. In this study, we tested the effects of the IPCC RPC6.0 end-of-century acidification scenario on a natural plankton community in the Gullmar Fjord, Sweden, during a long-term

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).

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.

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 ...
