A multigene phylogeny to infer the evolutionary history of Chaetocerotaceae (Bacillariophyta).
Molecular Phylogenetics and Evolution, 2019The diatom family Chaetocerotaceae (Bacillariophyta) is common in the marine plankton worldwide, especially in coastal areas and upwelling zones. Its defining character constitutes hollow processes, called setae, which emerge from the valves of the ...

Six new epibiotic Proschkinia (Bacillariophyta) species and new insights into the genus phylogeny
European journal of phycology, 2019The diatom genus Proschkinia is a common element of biofilms covering diverse substrata in saline inland or shallow coastal environments. It can be distinguished from other naviculoid taxa by its lanceolate valves with a fistula located within the ...

Diatoms are one of the most abundant and arguably the most species‐rich group of protists. Diatom species delimitation has often been based exclusively on the recognition of morphological discontinuities without investigation of other lines of evidence ...

Until now only one group of diatoms, the Bacillariaceae, was known to contain heterotrophic representatives. We show that a second group, represented by species in the genus Tursiocola, has undergone evolutionary loss of photosynthesis within the ...

Auxosporulation in Biddulphia tridens (Ehrenberg) Ehrenberg (Mediophyceae, Bacillariophyta)
, 2020We documented male and female gametogenesis, auxospore structure and development of the biddulphioid diatom species Biddulphia tridens (Ehrenberg) Ehrenberg, a close relative of the generitype. Our mating experiments showed that the B.

Two new aerophilic species of Stauroneis Ehrenberg (Bacillariophyta) from the Eastern Himalayas
Botany Letters, 2019Two new diatom taxa belonging to the genus Stauroneis Ehrenberg were discovered from an aerophilic habitat in Sikkim, India, a part of the Eastern Himalayas. The morphology of Stauroneis sikkimensis sp. nov. and Stauroneis lepchae sp. nov.
