Ocean Sciences Meeting

Pilina means connection, relationship, and association and is an important value in Hawaiian culture that encourages inclusivity and collaborations to achieve results that cannot be accomplished with one person alone. The 2022 OSM focuses on the importance of strong pilina for the ocean science community. By coming together, we can forge a path toward a sustainable future.

Virtual meeting for the Phycology section of the German Botanical Society

Dear algae researchers

Every two years the Section organizes a scientific meeting to facilitate the exchange on topics related to algal research in the German-speaking world. However, the upcoming meeting will not take place until spring 2023 due to Corona. To bridge the time until then, the Section organizes a small online meeting on March 16, 2022-March 17, 2022, preferentially targeting young researchers to give them a stage even in today’s difficult times.

In the following you can register for the participation in the conference. We will then send you all further information regarding the program as well as the access data.

EGU General Assembly in Vienna

The EGU General Assembly 2022 will bring together geoscientists from all over the world for one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists, especially early career scientists, can present their work and discuss their ideas with experts in all fields of geoscience.

The last two General Assemblies, Sharing Geoscience Online in 2020 and vEGU21: Gather Online, were organized as virtual meetings due to the Covid-related restrictions. In 2022, the EGU aims to provide an on-site experience again for those attending in-person, while at the same time introducing new concepts to include virtual attendees as much as possible. The EGU General Assembly 2022 (EGU22) will be a conference with a virtual component where everybody is welcome, in person or online! We plan for the format of the conference to be flexible, giving us the opportunity to more easily adapt to the uncertain global context.

14th European Diatom Meeting

The 14th European Diatom Meeting will take place at Lake Ohrid, North Macedonia, from the 9-11 May 2022. Lake Ohrid, a deep and ancient lake of tectonic origin, is a unique refuge for numerous endemic and relict freshwater species of fauna and flora, and the town of Ohrid is one of the oldest settlements in Europe and a major cultural centre.

The main topics of the meeting will be climate change and paleoecology, biomonitoring, evolution, phylogeny, systematics, taxonomy, biogeography, ecology, and diatom applications.  

The registration deadline is the 1 February 2022. For further details please visit   

The International Society for Diatom Research (ISDR), The Association of French Language Diatomists (ADLaF) and the Dutch-Flemish Society of Diatomists (NVKD) are providing financial support for the participation of 15 students which will cover the registration fee and accommodation during the conference. Students who would like to receive financial support should provide a letter of interest, CV and a recommendation letter by 1 March 2022.

Algae: Issues on Taxonomy and Ecology, Monitoring and Biotechnology Approaches

The Lomonosov Moscow State University and the K.A. Timiryazev Institute of Plant Physiology of the Russian Academy of Sciences invites diatomists to take part in the VI All-Russian Scientific Conference with international participation “ALGAE: ISSUES ON TAXONOMY AND ECOLOGY, MONITORING AND BIOTECHNOLOGY APPROACHES”.

The meeting will take place at the S.N. Skadovskiy Zvenigorod Biological Station, M.V. Lomonosov MSU, Moscow, Russia, from September 12-18th, 2022. The meeting covers all aspects of diatom research and the Conference Proceedings will be published in the journal “Issues of Modern Algology”

Further information and the conference application form is available on the website and from the conference organizer at

The deadline for submission of the conference application form is the 1st February 2022. Applicants will be sent the second circular on 1st March 2022 with detailed information about the conference.

Joint IPA-IAL 2022
The IAL IPA Joint Meeting 2022 will take place from November 27th to December 1st in Bariloche, Patagonia, Argentina. It will be an in-person event but with some streaming options for people who cannot attend the meeting in person. A new conference website has been launched and the call for sessions is now open. We hope as many of you as possible will be able to join us. The goal of the IAL IPA 2022 joint meeting is to celebrate research on lakes from multiple perspectives with a focus on the sediment record as both an Earth System Archive and a social and cultural memory of the landscape. This conference aims to bridge the gap across a broad range of disciplines that work within the overarching theme of Earth System and Climate-Environment-Cultural changes. The conference includes 4 days of oral and poster presentations, social events, conference courses, fieldtrips and beautiful landscapes. The registration fee includes ice-breaker, mid- conference activities, coffee breaks, lunchs and …yes ! the conference dinner.

The theme of the congress is “a Mediterranean perspective on Quaternary Sciences” since the Mediterranean region, so geologically young and active, is the ideal place where to discuss the processes and events that shaped the landscape, the environment and the ecosystems in the last 2.58 million years.

From the glacial systems in the Alps to the desert facing the southern shore, from the large coastal plains and deltas to the rocky coasts where the mountain ranges reach the sea, from the karst to the lacustrine to the volcanic environments, almost all of the Quaternary features are present in the region.

2024 International Botanical Congress

We are delighted and deeply honored to announce that the next International Botanical Congress ―the 20th IBC— will take place in Madrid (Spain) on the following dates:

Nomenclature Section, 15–19 July 2024
Congress, 21–27 July 2024

The IBC takes place every six years under the supervision of the International Association for Botanical and Mycological Societies (IABMS). The 20th was scheduled to take place in 2023 in Brazil after Shenzhen’s (China) 2017. Unfortunately, the difficult situation caused by the worldwide pandemic has made impossible to organize this big event in Brazil in 2023.
Rooted in the tradition of Systematic Botany, the IBCs have enlarged their scope over more than a century to become an integrated forum for knowledge on the plant and mycological world. Please take a look at the broad scope of topics that we hope to include in this upcoming IBC in this site.
The Congress will include plenary lectures, concurrent symposia ―for which we will ask for proposals in Spring 2022—, posters, exhibitors, as well as short courses and workshops.
We wholeheartedly invite all the botanical community worldwide to come to participate in the 20th IBC and enjoy, in Madrid, the privilege of sharing research, knowledge and experiences with colleagues and friends from all over the planet. We will make efforts to provide the best environment for such a thrilling experience.
A suite of post-meeting excursions will be offered for attendees to visit places of botanical and cultural interest. See the preliminary list in this site.
We look forward to seeing you all in Madrid in July 2024.

Kind regards,
The Organizing Committee of the 20th IBC
