A latest Cretaceous to earliest Paleogene dinoflagellate cyst zonation of Antarctica, and implications for phytoprovincialism in the high southern latitudes [PDF]

open access: yes, 2012
The thickest uppermost Cretaceous to lowermost Paleogene (Maastrichtian to Danian) sedimentary succession in the world is exposed on southern Seymour Island (65° South) in the James Ross Basin, Antarctic Peninsula.

Microphytoplankton biozonation of late Albian - Turonian succession in Famo-1 well, Gongola Sub Basin, Upper Benue Trough, Nigeria

open access: yesJournal of Applied Sciences and Environmental Management, 2018
A comprehensive palynological (Dinoflagellate Cyst) study of 35 ditch cutting samples recovered from Late Albian to Turonian succession penetrated by Famo-1 well in the Gongola sub Basin, Upper Benue Trough, North East, Nigeria, generated ...

Sexual Reproduction in Dinoflagellates—The Case of Noctiluca scintillans and Its Ecological Implications

open access: yesFrontiers in Marine Science, 2021
Noctiluca scintillans is a larger, bioluminescent red-tide dinoflagellate (400–1,000 μm in diameter) that reproduces by sexual or asexual reproduction (binary fission). The process of sexual reproduction in N. scintillans has been thoroughly studied, but

An effective palynological preparation procedure using hydrogen peroxide [PDF]

open access: yes, 2007
Most pre-Quaternary palynology samples are currently prepared by demineralization of the sediment/sedimentary rock matrix using hydrochloric and hydrofluoric acids (HCl and HF respectively).

Bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii Chatton 1914 (Dinophyceae). [PDF]

open access: yesJ Phycol
Abstract Heterotrophic dinoflagellates are important predators of phytoplankton, and many species produce bioluminescence, which is thought to serve as an antipredator function. The present study investigated the bioluminescence of the heterotrophic dinoflagellate Polykrikos kofoidii, an important predator of toxic and bloom‐forming dinoflagellates ...

A Strategy for Gene Knockdown in Dinoflagellates

open access: yesMicroorganisms, 2022
Dinoflagellates are unicellular protists that display unusual nuclear features such as large genomes, condensed chromosomes and multiple gene copies organized as tandem gene arrays.

Seasonal changes in microbial dissolved organic sulfur transformations in coastal waters [PDF]

open access: yes, 2020
The marine trace gas dimethylsulfide (DMS) is the single most important biogenic source of atmospheric sulfur, accounting for up to 80% of global biogenic sulfur emissions.

Dinoflagellates, a Unique Lineage for Retrogene Research

open access: yesFrontiers in Microbiology, 2018
The birth and evolution of retrogenes have played crucial roles in genome evolution. Dinoflagellates represent a unique lineage for retrogene research because the retrogenes can be reliably identified by the presence of a 22 nucleotide splice leader ...

Differences in the chemical composition of organic-walled dinoflagellate resting cysts from phototrophic and heterotrophic dinoflagellates [PDF]

open access: yes, 2013
Dinoflagellates constitute a large proportion of the planktonic biomass from marine to freshwater environments. Some species produce a preservable organic-walled resting cyst (dinocyst) during the sexual phase of their life cycle that is an important ...
