The paratabulate calcareous cyst of Calciodinellum operosum Deflandre was recorded in a sediment trap sample collected in the Bay of Naples (Tyrrhenian Sea, Italy). The germination of this resting stage produced a phototrophic vegetative cell that had the typical plate pattern of a Scrippsiella species. The cyst morphotypes, observed in a clonal culture of this species, ranged from cysts with well‐developed paratabulation to cysts in which the paratabulation was barely visible, to cysts covered… Expand
Scrippsiella trochoidea and scrippsiella regalis, nov. comb. (peridiniales, dinophyceae): a comparison
Culture experiments on dinoflagellates from the Atlantic Ocean revealed Scrippsiella regalis (Gaarder) Janofske, nov. comb., a calciodinelloid species with a spherical spiny calcareous cyst. ThisExpand
Diversity and morphology of calcareous dinophytes (Thoracosphaeraceae, Peridiniales)
TLDR
Comparative ultrastructure investigations using light and electron microscopic techniques at various stages of the life cycle showed that the anatomical structure during the biomineralization processes differs within subgroups of calcareous dinophytes and could be used as a useful phylogenetic trait. Expand
PHYLOGENETIC POSITION AND MORPHOLOGY OF THECAE AND CYSTS OF SCRIPPSIELLA (DINOPHYCEAE) SPECIES IN THE EAST CHINA SEA 1
TLDR
Results of internal transcribed spacer (ITS) sequence comparisons revealed that S. donghaienis was distinct from the S. trochoidea complex and appeared nested within the Calciodinellum/Calcigonellum clade. Expand
An Updated List of Generic Names in the Thoracosphaeraceae
TLDR
A brief synopsis about the taxonomic history of the Thoracosphaeraceae is provided, from the first descriptions of fossils in the 19th century through to the results of molecular phylogenetics studies undertaken during the past two decades. Expand
THE CYST OF THE CALCAREOUS DINOFLAGELLATE SCRIPPSIELLA TRIFIDA: RESOLVING THE FOSSIL RECORD OF ITS ORGANIC WALL WITH THAT OF ALEXANDRIUM TAMARENSE
TLDR
It is apparent from this distribution that Scrippsiella trifida favors neritic environments characterized by cool winters and relatively warm summers, and the organic walls of calcareous dinoflagellate cysts are more common components of palynological assemblages than hitherto realized. Expand
Different excystment patterns in two calcareous cyst-producing species of the dinoflagellate genus Scrippsiella
TLDR
Differences in dormancy length may partially explain the distinct cyst production patterns observed for the two species in the Gulf of Naples, suggesting a high physiological diversity within the cyst pool. Expand
TOWARD AN ASSESSMENT ON THE TAXONOMY OF DINOFLAGELLATES THAT PRODUCE CALCAREOUS CYSTS (CALCIODINELLOIDEAE, DINOPHYCEAE): A MORPHOLOGICAL AND MOLECULAR APPROACH
TLDR
The coupled morphological and molecular approach supports the taxonomic value of some of the characters of the planktonic stage, such as the cingular plate number, but questions the validity of other morphological characters of both vegetative and encysted stages. Expand
Morphology and phylogeny of Pentapharsodinium jinhaense sp. nov. (Dinophyceae) producing a calcareous resting cyst
Abstract: A new species, Pentapharsodinium jinhaense sp. nov., was established by incubating resting cysts, which were collected from trap samples from Jinhae-Masan Bay, Korea. The resting cysts ofExpand
CYST-THECA RELATIONSHIPS OF GONYAULACALES AND PERIDINIALES (DINOPHYCEAE) FROM BAHÍA CONCEPCIÓN, GULF
TLDR
The previously unknown cyst-theca relationship of P. globosum was described and the presence of the vegetative stage of G. denticulatum in the Gulf of California and heterospory in G. spinifera from Bahia Concepcion was confirmed. Expand
SAME BUT DIFFERENT: TWO NOVEL BICARINATE SPECIES OF EXTANT CALCAREOUS DINOPHYTES (THORACOSPHAERACEAE, PERIDINIALES) FROM THE MEDITERRANEAN SEA 1
TLDR
Bicarinate cingulotabulation appears homoplasious among calcareous dinophytes, which is further supported by a comparison to similar, but only distantly related fossil forms. Expand
