Young diatomists! We want to provide you with Workshops around the 25th International Diatom Symposium in Berlin. To do that, we wanted to cater to your particular needs and have created a poll to see which subjects are most interesting for you. If you don't find a subject to your liking, comment under the doodle to give us a chance of adding it. The poll will close at September 22nd.  The subjects that you vote most for will be the ones that we organize, so, please, get voting!

Early-career diatomists meet in the International Phycological Congress in Poland

Image
Phycologists (researchers that study plant and algal biology) from all over the world came to present their up-to-date research in the the 11th International Phycological Congress (IPC) at Szczecin. Even though weather conditions were changing, the atmosphere at the congress was great. We started each day with superb plenary sessions about the communication leading to the reproductive system of diatoms and their silification mecanisms and the evolutionary imprint on the macromolecular composition of diatoms. Also on the programme were multiple invited symposia of variable themes, such as bioprospecting, diatom (or microalgal) biogeography, nomenclature, palaeontology and ecological metabarcoding. Finally, many excellent contributed symposia were given, the star of the show being Seminavis robusta with at least 4 talks. There were many more talks on other microalgae, macroalgae and their ecologies, too. From Young Diatomists we would like to wholeheartedly thank the organizers, Andrzej …

The role of geology behind diatom communities

Geological setting in Finland The last glaciation, approximately 10 000 years ago, eroded and deposited material leaving behind a landscape full of glacial landforms in northern Europe. These landforms include thick layers of basal tills, glaciofluvial eskers, and moraines, to name a few. The retreating glacier also left behind a multitude of lakes in Finland. These lakes are often shallow and elongated in the direction of the ice flow. A majority of the lakes are located in central-eastern Finland, called the Finnish Lake District, where a relatively coarse-grained basal till covers most of the land surface. These tills deposited under actively flowing ice lobes that flushed away the finer materials. However, in the intersection of two actively flowing ice lobes, a passive interlobate area formed. This wedge-shaped area pierces central Finland in a NW-SE direction and is characterized by fine-grained basal till. The coastal areas of Finland, on the other hand, were under water after …
