Warming enhances protozooplankton top‐down control and nutrient competition

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Protozooplankton regulate microbial food webs through top‐down control and nutrient cycling, yet their grazing impacts under ocean warming, particularly in subsurface chlorophyll maximum (SCM) layers, remain poorly understood. This study investigated spatial and seasonal variability in protozooplankton grazing in the northern East China Sea ...

Micro- and nanoplastics in freshwater ecosystems—interaction with and impact upon bacterivorous ciliates

open access: yesFrontiers in Earth Science
The ubiquitous occurrence of microplastics and nanoplastics in aquatic environments is of major concern as these priority pollutants are readily ingested by a wide variety of aquatic organisms.

Microzooplankton stoichiometric plasticity inferred from modelling mesocosm experiments in the Peruvian Upwelling region

open access: yesFrontiers in Marine Science, 2016
Oxygen minimum zones (OMZs) are often characterised by nitrogen-to-phosphorus (N:P) ratios far lower than the canonical Redfield ratio. Whereas the importance of variable stoichiometry in phytoplankton has long been recognised, variations in zooplankton ...

Estimating Carbon Pools in the European Shelf Sea Environment: Replacing Reanalysis by Model‐Informed Machine Learning?

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Shelf seas are important for the economy and the carbon cycle, but shelf sea observations for carbon pools are often sparse or highly uncertain. An alternative can be provided by carbon reanalyses (whether assimilating proxy variables, such as chlorophyll‐a $a$, or directly carbon), but these are often expensive to run.

Dilution effects on microzooplankton in dilution grazing experiments [PDF]

open access: yesMarine Ecology Progress Series, 2000
In dilution experiments, filtered seawater is used to create a gradient of grazing pressure on phytoplankton. Microzooplankton grazing is estimated by examining phytoplankton growth within the gradient. However, the dilution series also represents a resource gradient for microzooplankton. Here we report the effects of dilution on grazers. In 2 standard

Can manipulative parasites modify host‐mediated trophic effects? Experimental evidence from Schistocephalus solidus and three‐spined sticklebacks

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1603-1618, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Parasites can alter host traits, thereby reshaping host interactions and modifying density‐ and trait‐mediated effects in trophic cascades. But despite increasing research in parasite ecology, the cascading effects of parasitism from individual hosts to population and ...

Analyzing the Impacts of Elevated-CO2 Levels on the Development of a Subtropical Zooplankton Community During Oligotrophic Conditions and Simulated Upwelling

open access: yesFrontiers in Marine Science, 2019
Ocean acidification (OA) is affecting marine ecosystems through changes in carbonate chemistry that may influence consumers of phytoplankton, often via trophic pathways.

Identifying the Environmental Drivers of Spatial Variability in Zooplankton Community Grazing Dynamics

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Biogeochemical models used to estimate carbon export fluxes are highly sensitive to their parameterization of zooplankton grazing dynamics. Zooplankton grazing dynamics have been shown to vary spatially, however it is less clear how they are responding to underlying environmental drivers.

Storm-Induced Predator-Prey Decoupling Promotes Springtime Accumulation of North Atlantic Phytoplankton

open access: yesFrontiers in Marine Science, 2019
We examined the response of North Atlantic plankton population dynamics to rapid re-stratification of surface waters following a deep mixing event during spring.
