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 …

The term 'Ubiquitous name'is created and discussed. A 'ubiquitous name'is a taxon name

 Abstract This study deals with Ulnaria species found and described from two regions of
China with large climate differences during the period of 2014–2022. The first region …

Currently, microeukaryotic communities of the freshwater arctic and subarctic ecosystems
are poorly studied. Still, these are of considerable interest due to the species biogeography …

Multiple ecological and genetic studies of diatom algae require an axenic culture. However,
algae-associated bacterial biofilms often form in diatom-produced mucus, both during …

Araphid diatoms of the genus Ulnaria are the dominant species in many freshwater
ecosystems of Eurasia. Diatom populations are genetically heterogeneous and represent a …
