Diatoms (Bacillariophyta) are ubiquitous microalgae which produce a siliceous exoskeleton
and which make a major contribution to the productivity of oceans and freshwaters. They …

Four species of Gomphonema described by Hustedt with fusiform valve shape are studied
for the first time using SEM. G. longissimum Hustedt, G. angustissimum Hustedt, G …

Large, old and heterogenous lake systems are valuable sources of biodiversity. The
analysis of current spatial variability within such lakes increases our understanding of the …

Diatoms are a group of eukaryotic microalgae populating almost all aquatic and wet
environments. Their abundance and species diversity make these organisms significant …

Fragilaria and Ulnaria are two closely related diatom genera for which the delimitation and
circumscription of several species is unclear. We studied strains isolated from Lake Baikal …

For the first time, a giant diatom species of the genus Cymbella from Lake Baikal was
studied using molecular methods. Molecular and morphological investigations allowed to us …

During this investigation, sixteen species from the genus Gomphonema were found in a
shallow bay (near Oimur, Kabansky District) located on the eastern shore of Lake Baikal …

Many organisms including unicellular (diatoms, radiolaria, and chrysophytes), higher plants
(rice and horsetail) and animals (sponges) use silica as a main part of skeletons. The …

Molecular phylogenetic analyses place Ardissonea crystallina (C. Agardh) Grunow and all
Toxariids among the bi-and multipolar centric diatoms, almost always recovered as a …

A new monoraphid diatom species Achnanthidium tinea Tseplik, Kulikovskiy, Kociolek &
Maltsev, sp. nov. is described from Indonesia. The species is described on the basis of …
