It also provides a premier interdisciplinary platform for researchers, practitioners and educators to present and discuss the most recent innovations, trends, and concerns as well as practical challenges encountered and solutions adopted in the fields of Applied Phycology.

9th Asian Pacific Phycological Forum

The 9th Asian Pacific Phycological Forum (APPF 2020) was scheduled to be held in Sapporo, Japan, but was postponed due to the Covid-19 pandemic. Now, the APPF will be held in April, 2024, in Sapporo, Japan as APPF 2024, not online or as a hybrid, but in person.

The APPF is a conference held by the Asian Pacific Phycological Association. The conference, held every three years, is an opportunity for researchers and engineers to gather and exchange ideas and acquire knowledge in a wide range of fields related to algae including basic biology and the applied sciences. To date, the Asia Pacific Phycological Forum has been held in eight countries: Australia (1996), Hong Kong (1999), Japan (2002), Thailand (2005), New Zealand (2008), Korea (2011), China (2014), and Malaysia (2017). The 9th APPF (2024) will be held at Hokkaido University in Sapporo, Japan. Hokkaido University has a long history dedicated to the study of algal biology. The theme of the APPF 2024 forum will be “Algae: Biodiversity, Evolution and Sustainable Development Goals (SDGs)”. Sapporo is Japan’s 5th largest city and is located on Japan’s North Island, Hokkaido. The city is a popular tourist destination, due to its surrounding nature and pleasant climate. We warmly invite you to attend the APPF 2024 and look forward to your presentations.

SIL Congress 2024 Brazil

After almost 30 years, Brazil is once again hosting a SIL International Congress on Limnology. As a historical indigenous land, Latin America and the Caribbean are blessed with incredible water resources and breathtaking landscapes! However, the fragmentation of the indigenous people and water bodies across the continent has led to scientific and economic inequalities with serious consequences for biodiversity conservation.

The diversity of water bodies in Latin American and the Caribbean is as great as their indigenous people and their culture, which are fully connected to the water. For these people and their descendents, freshwaters are considered a holy ground, a gift supporting the dignity of their people and ancestors. These characteristics make Brazil a relevant site to host this global Limnology event.

Therefore, in 2022, limnologists from 18 countries came together to reduce such distances and borders, in an effort to restore part of the connections between people and waters over these incredible territories!

The theme for the 37th SIL Congress is “Building bridges between science and society to reduce the effects of fragmentation and degradation of inland waters”. By bringing together researchers, policymakers, and stakeholders, it aims to reconcile the multiple uses of the water with the challenges for conservation in the face of climate change and human pressures. In this regard, the main issue we want to address is the legacy that we will need to leave in a fragmented world, where indigenous and non-indigenous people need to work together for a sustainable land.

15th European Diatom Meeting

The 15th European Diatom Meeting at Lake Ohrid, North Macedonia, has been postponed to 2024. 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.

ASLO 2024 in Madison, Wisconsin, USA

The world is rapidly changing. The accelerating tempo of climate change, eutrophication, altered hydrological regimes, overharvest, and biodiversity loss are threatening aquatic ecosystems, water resources, and resultant human well-being. Effectively adapting to meet these challenges will require major transitions in both our thinking and how we manage aquatic ecosystems to build resilience. Sustainable solutions—those that work across sectors, nations, and generations—will emerge from a foundation of actionable aquatic science.

By proposing a special session, we hope you’ll help highlight relevant work on aquatic ecosystems in a changing world, and how aquatic organisms, ecosystems, and management are adapting to global environmental change.

The ISAP is a non-profit organization that aims to promote research, preservation of algal genotypes, and the dissemination of knowledge concerning the utilization of algae.

ISAP has nearly 500 supporters worldwide from more than 40 countries. Of these supporters, there are representatives of industry and scientific researchers with expertise spanning all applied aspects of microalgae and macroalgae, and student members across the world.

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

8th European Phycological Congress in Brest, France

After Zagreb in 2019, we are pleased to invite you to Brest (Brittany, France) for the 8th European Phycological Congress “Scientific Opportunities for a Global Algal Revolution” on behalf of the Federation of European Phycological Societies council and the French Phycological Society. France has a long and proud tradition of phycological research and has a very diverse algal flora. Brittany is a world hotspot for seaweed diversity with about 700 species and has historically developed a flourishing macroalgal industry that still maintains its leadership in Europe. The region also hosts important research institutes dedicated to microalgae research and oceanography.

The European Phycological Congress series began in Cologne, Germany in 1996 and has since continued the tradition of bringing together phycologists from around the world every four years. Its main objective is to provide a forum for discussion of the latest scientific, technological and societal developments in phycological research. EPC8 includes plenary presentations, a series of symposia grouped into 6 themes, contributed papers and posters covering a wide range of topics such as algal diversity, ecology, genomics, cell biology, applied phycology and societal perception of algae. To encourage cross-community connections, each symposium will address micro- and macroalgae from marine, freshwater, and terrestrial ecosystems whenever possible. We look forward to welcoming you to Brest in August 2023 for EPC8!

On behalf of the organizing committees, Solène Connan and Philippe Potin
