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.

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

open access: yesFrontiers 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

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 ...

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.

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.

Assemblage organization over time prevents invasion success in phytoplankton

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Invasion plays a central role in long‐term species coexistence, sometimes rejuvenating diversity and, at other times, collapsing it. Community resistance to invasions depends partly on species richness and structure, both of which change with community organization over time.

Synthetic pelagic biomass size spectra of the tropical and subtropical Atlantic

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Synthetic normalized biomass size spectra (NBSS) comprising non‐synoptically sampled phytoplankton, meso‐ and macrozooplankton, and micronekton including mesopelagic fishes were explored to analyze pelagic community structure in seven regions of the tropical and the subtropical Atlantic representative of different water bodies (NE Brazil shelf,

Unraveling Long‐Term Microsporidia Diversity and Dynamics in Lake Aydat (France) Through Paleogenomics

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Sedimentary ancient DNA study revealed 138 years of hidden microsporidian (unicellular eukaryotic parasite) diversity and host–parasite dynamics in a freshwater lake. A major community shift in the 2000s, linked to anthropogenic pressures, shows how paleogenomics reveals the diversity and long‐term ecological trajectories of these previously overlooked

Major contribution of prokaryotes to carbon fluxes in the pelagic microbial food webs of the Mediterranean Sea

open access: yesAdvances in Oceanography and Limnology, 2016
In this study, we carried out dilution experiments at the surface and in the mesopelagic and bathypelagic layers at 15 sites in the Mediterranean Sea that covered a wide range of trophic conditions.

Surface slicks structure microbial and viral neuston in relation to biogeochemical conditions

open access: yesLimnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract The sea‐surface microlayer (hereafter microlayer), which forms the interface between the ocean and atmosphere, plays a key role in nutrient cycling and microbial dynamics. Coastal slicks, which are viscous and biogenic surface films, often serve as hotspots for microbial activity, yet their structure and interactions remain incompletely ...
