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 ...

Evidence for Limited Atmospheric CO2 Rise at the Miocene Climatic Optimum
Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a relatively warm period with atmospheric CO2 averaging ∼500 μatm but CO2 change across its onset is poorly documented. We present a record of algal 13C‐fractionation covering the Early to Middle Miocene (∼18.5–15 Ma), with a gap at the MCO onset, from Ocean Drilling Program Site 959 in the ...

Recent advances in dinoflagellate cyst: Integrating review with visual taxonomic perspectives
Ecological InformaticsResting cysts are a critical stage in the life cycle of certain dinoflagellates, involving active growth, sexual reproduction, and dormancy. With the global rise in harmful algal blooms (HABs), interest in the ecological roles of these cysts has grown ...

Geologica Balcanica, 1994 Tithonian marine sediments from 34 boreholes and one outcrop in North Bulgaria have been palynologically examined. They contain rich anа commonly well preserved dinocyst assemblages. This paper includes brief comments on morphology, taxonomy, geographic and stratigraphic distribution of 56 dinocyst taxa and 2 acritarch species which start ill this ...

Petroleum geology of the Upper Jurassic – Lower Cretaceous of East and North-East Greenland: Blokelv-1 borehole, Jameson Land Basin: Biostratigraphy of the Hareelv Formation (Upper Jurassic) in the Blokelv-1 core, Jameson Land, central East Greenland [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2018 The Hareelv Formation in the Blokelv-1 core is biostratigraphically subdivided by means of ammonite and dinoflagellate cyst stratigraphy. The succession ranges from the Oxfordian C. densiplicatum Chronozone to the Volgian P. elegans Chronozone.
