Trait‐based responses of nitrogen‐fixing cyanobacteria to nitrogen limitation and light availability: Insights from 45 years of monitoring

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract The degree to which N2‐fixation compensates for reduced external nitrogen loading has significant implications for eutrophication recovery. We analyzed 45 years of monitoring data from the shallow, polymictic Lake Müggelsee during which external P‐ and N‐loading declined by about 80% and there were extended periods of N‐limitation in summer ...

Dinoflagellate responses to nutrients and mangrove leaf organic matter in the bioluminescent Mangrove Lagoon, St. Croix, U.S. Virgin Islands

Journal of Phycology, Volume 62, Issue 4, Page 1240-1250, August 2026.
Abstract Bioluminescent bays (biobays) are uncommon coastal ecosystems featuring dense populations of dinoflagellates, often found in mangrove‐ringed lagoons with long water retention times and high organic matter (OM) levels. Although mangroves are associated with high dinoflagellate abundance, it remains uncertain how inorganic nutrients compare with

A review of the Sentusidinium complex of dinoflagellate cysts [PDF]

Review of Palaeobotany and Palynology, 2016
The Jurassic to Neogene (Miocene) dinoflagellate cyst genus Sentusidinium has a relatively simple overall morphology. This genus, together with Batiacasphaera, Kallosphaeridium and Pentafidia, comprises the Sentusidinium complex. This is distinct from the superficially similar laterally asymmetrical and subspheroidal/lenticular Cyclonephelium complex ...

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.

A southern North Sea Miocene dinoflagellate cyst zonation [PDF]

Netherlands Journal of Geosciences - Geologie en Mijnbouw, 2004
AbstractAn integrated stratigraphical analysis emphasizing organic-walled dinoflagellate cyst (dinocyst) distribution has been carried out on multiple boreholes penetrating the Miocene in the subsurface of the Netherlands (southern North Sea Basin).

First evidence of Campanian-Maastrichtian shallow marine deposits from eastern Atlantic margin (Doualasub-basin, Cameroon): Palynological and sedimentological approaches

Geosystems and Geoenvironment
Integration of facies analysis with organic microfossils (mainly dinoflagellate cysts) provides insights into the paleoenvironmental reconstruction of the onshore part of the Douala sub-basin of Cameroon.

Metabarcoding of Broad‐Diet Nototheniid Fish Stomachs Reveals Newly Detected Antarctic Parasite Signals and Potential Host Associations

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Using 18S rDNA metabarcoding of stomach contents from two Antarctic nototheniid fishes, we detected 242 parasite OTUs. Protists dominated diversity, metazoans dominated abundance, and depth structured assemblages. Novel parasite–host associations and previously unreported pathogenic protists highlight fish metabarcoding as a tool for biodiversity and ...

Spiniferites cruciformis: a fresh water dinoflagellate cyst?

Review of Palaeobotany and Palynology, 2001
Palynological studies of cored lacustrine sediments from the late Quaternary of Lake Kastoria, northern Greece, revealed a Late Glacial interval with abundant dinoflagellate cysts. Cyst assemblages include two identifiable species, Spiniferites cruciformis and Gonyaulax apiculata. The presence of the fresh water species G.

An updated view on the long‐term survival and significance of marine protist resting stages

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Resting stages of protists act as biological time capsules when buried in marine sediments, preserving viable cells that enable the study of ecological and evolutionary processes across timescales. Recent studies have extended the known viability in diatoms to several millennia and in dinoflagellates to over a century, while also identifying ...

Transcriptome and metabolome analyses of cold and darkness-induced pellicle cysts of Scrippsiella trochoidea

BMC Genomics, 2021
Background Dinoflagellates are a group of unicellular organisms that are a major component of aquatic eukaryotes and important contributors to marine primary production.
