Revisiting the life cycle of Margalefidinium polykrikoides Group III

Journal of Phycology, Volume 62, Issue 4, Page 1367-1382, August 2026.
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

The enigmatic nucleus of the marine dinoflagellate Prorocentrum cordatum

mSphere, 2023
The marine, bloom-forming dinoflagellate Prorocentrum cordatum CCMP 1329 (formerly P. minimum) has a genome atypical of eukaryotes, with a large size of ~4.15 Gbp, organized in plentiful, highly condensed chromosomes and packed in a dinoflagellate ...

Emerging occurrence of Gambierdiscus carolinianus in the Azores: The northernmost Atlantic record

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract The dinoflagellate genus Gambierdiscus was detected for the first time in the Azores Archipelago, representing its northernmost record to date (> 39°N). Two strains were isolated from macroalgal substrates on Corvo and Faial Islands during the summer of 2024, coinciding with a marine heatwave in which sea‐surface temperature anomalies exceeded

Diverse Bacterial PKS Sequences Derived From Okadaic Acid-Producing Dinoflagellates

Marine Drugs, 2008
Okadaic acid (OA) and the related dinophysistoxins are isolated from dinoflagellates of the genus Prorocentrum and Dinophysis. Bacteria of the Roseobacter group have been associated with okadaic acid producing dinoflagellates and have been previously ...

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

Environmental Toxicology, Volume 41, Issue 7, Page 379-394, July 2026.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

Quantifying Shifts in the Absorption Budget of the Labrador Sea as the Dominant Phytoplankton Group Changes Between Diatoms and Phaeocystis

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Phytoplankton spring blooms in the Labrador Sea are dominated by diatoms, with Phaeocystis spp. (hereafter Phaeocystis) contributing more than 25% to total phytoplankton biomass. However, in 2015 and 2022, large blooms of Phaeocystis were observed, contributing up to 90% of the surface phytoplankton biomass. In this study, we quantified shifts

pr2‐Wormifier: A Bioinformatics Pipeline to Create Custom Reference Databases for Improved Metabarcoding of Marine Protists

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Metabarcoding of environmental and ancient environmental DNA (eDNA and sedaDNA) is a powerful approach for studying and monitoring marine communities. However, its effectiveness is limited by the availability of comprehensive and well‐curated reference databases, particularly for protists.

Rapid sexual reproduction intensifies blooms of a mixotrophic dinoflagellate

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Sexual reproduction is fundamental to the ecology and evolution of eukaryotes, yet its dynamics in microbial eukaryotes are often cryptic. Dinophysis are specialist mixotrophs that must balance prey capture, cell division, and sexual recombination during blooms, but relatively little is known about the occurrence and role of sex in their ...
