About The Meeting

The 13th European Diatom Meeting (formerly Central European Diatom Meeting) will be hosted online by Amgueddfa Cymru – National Museum Wales. It brings together scientists from Europe and further afield to discuss a broad range of topics in diatom research. Keynote lectures and oral presentations are scheduled for 2nd and 3rd March 2021, followed by a one-day taxonomic workshop on the complex of species in the Fragilaria capucina group.

Workshop on the Fragilaria capucina complex

Bart Van de Vijver, Meise Botanic Garden, Belgium
Adrienne Mertens, Diatomella, Netherlands
Luc Ector, Carlos Wetzel, Luxembourg Institute of Science and Technology, Luxembourg

The workshop on the complex of species in the Fragilaria capucina group will consist of two parts. During the morning sessions, lectures will document and discuss all species in this group. In the afternoon, selected species will be illustrated using light microscopy and material from type slides and other populations from Europe.

Lecture 1


Lecture 2

Conference Venue

Originally the meeting was due to be held at Amgueddfa Cymru – National Museum Wales, St Fagans National Museum of History. Due to the Covid-19 outbreak in the spring of 2020 we unfortunately had to cancel the conference and instead the meeting is now being hosted virtually.

As one of Wales' most popular visitor attractions we still felt it would be nice to showcase the museum should you ever get the chance to visit in the future once we reopen to the public.

St Fagans National Museum of History

St Fagans National Museum of History has completed its Making History redevelopment project in 2018 with the opening of new galleries and state-of-the-art conference and workshop places. It is one of Wales’ most popular visitor attractions offering an exciting collection of historic buildings, heritage objects, and public programmes, to create history with the people of Wales. In 2019 it was declared the winner of the Art Fund Museum of the Year, the largest arts award in Britain. The Museum is located in a 100-acre parkland with over forty original buildings from different historical periods.
