Warming effects on marine microzooplankton and mixoplankton: Physiological responses, community reorganization, and implications for a warming ocean

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Microzooplankton and mixoplankton are key regulators of marine food webs, yet their responses to ocean warming and thermal extremes remain incompletely integrated across physiological, community, and ecosystem scales. This synthesis examines how temperature shapes the physiology, trophic strategies, and community dynamics of these protistan ...

Contrasting Controls on Microzooplankton Grazing and Viral Infection of Microbial Prey

Frontiers in Marine Science, 2019
The encounter and capture of bacteria and phytoplankton by microbial predators and parasites is fundamental to marine ecosystem organization and activity.

Modulation of Cilia Beat Kinematics Is a Key Determinant of Encounter Rate and Selectivity in Tintinnid Ciliates

Frontiers in Marine Science, 2022
Tintinnids are a group of ciliated microzooplankton, who spontaneously settle on marine snow and other aggregates. Tintinnids create a feeding current that draws particles towards their mouth using a crown of continuously beating oral cilia. Similarly to

Revisiting the status of the Arctic's Last Ice Area as a refuge for marine predators

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract The Last Ice Area (LIA), located north of the Canadian Arctic Archipelago and Greenland, has the Arctic's oldest and thickest sea ice. The LIA is hypothesized to be a potential climate refuge for ice‐dependent top predators as Arctic sea ice continues to decline.

Microzooplankton as a bioindicator of environmental degradation in the Amazon

Ecological Indicators, 2016
Abstract Recent studies have assessed the impact of the discharge of untreated domestic and industrial effluents on aquatic ecosystems. In the 1980s, large industrial factories were set up in the municipality of Barcarena, Amazon, Brazil; however, this was not accompanied by investments to improve basic sanitation and housing structures in the region,

Copepod community structure and physiological rates shape the biological pump during early North Atlantic spring bloom

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Zooplankton plays an important role in the biological carbon pump, and zooplankton biomass and community structure can have a large influence on the sedimentation/remineralization balance of the water column. We investigated the potential effects of zooplankton community structure and eco‐physiology on the export and attenuation of vertical ...

Opportunistic feeding by Antarctic krill in the eastern Weddell Gyre

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Antarctic krill, Euphausia superba, is an important species in the Southern Ocean and is vulnerable to climate change. We studied the carbon sources for krill—specifically pelagic and ice‐associated (sympagic) particulate organic matter (POM), representing phytoplankton and sea‐ice algae, respectively—during March 2019 across three distinct ...

Diel dynamics of zooplankton fecal pellet flux revealed by integrated in situ imaging observations and modeling

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract The contribution of sinking fecal pellets to the biological carbon pump depends on pellet properties, producer abundance, and the depth and timing of pellet production, which can be modulated by diel vertical migration. We examined diel variability in zooplankton fecal pellet flux in the subarctic Northeast Pacific using two image‐based tools:

Phytoplankton Growth and Microzooplankton Grazing in the Subtropical Northeast Atlantic

PLoS ONE, 2013
Dilution experiments were performed to estimate phytoplankton growth and microzooplankton grazing rates during two Lagrangian surveys in inner and eastern locations of the Eastern North Atlantic Subtropical Gyre province (NAST-E). Our design included two phytoplankton size fractions (0.2-5 µm and >5 µm) and five depths, allowing us to characterize ...

Planktonic food web structure at SSTF and PF in the Indian sector of the Southern Ocean during austral summer 2011

Polar Research, 2018
This study aims to describe the planktonic food web structure with respect to phytoplankton biomass (chlorophyll a) and prevailing environmental conditions at the South Subtropical Front (SSTF) and the Polar Front (PF) in the Indian sector of the ...
