European Congress of Conservation Biology

The European Congress of Conservation Biology (ECCB) is a series of professional meetings organized by the Europe Section of the Society for Conservation Biology (SCB). ECCB aims to facilitate the exchange of conservation science and nature conservation practice and policy to promote the conservation of biological diversity in Europe.

This in-person congress, titled “Aquatic Ecosystems Under Threat: Advancing Our Knowledge to Mitigate the Effects of Global Change, Promote Adaptive Management, and Engage Citizens,” aims to bring together limnologists from Portugal, Spain, and other regions/nationalities to share and exchange knowledge and experience. It also aims to gather political and environmental stakeholders, industry representatives, and all those interested in aquatic ecological research and building an environmentally sustainable future. This will be a great opportunity to interact and exchange insights among limnologists directly, for the first time in Galicia.

The Iberian Association of Limnology extends a warm welcome to all its members and the global limnological community to attend the congress in Vigo next June. Come and participate!

Second European Congress for Photosynthesis Research (ePS2)

After the success of the first edition, the European Congress for Photosynthesis Research will come back in 2024. From June the 25th to the 28th 2024, experts in the field of natural and artificial photosynthesis will gather in Padova (Italy), the cradle of the scientific method developed by Galileo, for an exciting second edition of this scientific event.

Most of the industrial processes that sustain our economy have a remarkable impact on the environment. Our society must face the unavoidable challenge to increase sustainability of mankind activities to preserve our current way of life on the long term.

Over a history of three-billions-years, photosynthesis mastered the ability to harness the power of solar light for the generation of chemical energy, whilst also capturing atmospheric carbon. It represents a natural alternative to the current industrial processes that make our economy depending on fossil fuels and responsible for carbon emissions that lead to climate change.

More than ever, research in the field of photosynthesis is timely to ultimately develop light-driven industrial processes for the mitigation of the environmental damages already generated and the improvement of a sustainable economy for a greener future.

This objective calls for the deployment of a multipronged endeavour, where biophysical and biochemical approaches are conducted in parallel to molecular and metabolic investigations, in a multidisciplinary effort that the Second European Congress for Photosynthesis Research aims to celebrate.

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!

International Phycological Congress in Bohol (Phillipines)

The International Phycological Society (IPS), established in 1960, is committed to advancing the field of phycology by fostering the dissemination of phycological knowledge and promoting global collaboration among phycologists and related organizations. Incorporated as a non-profit public benefit corporation in the State of California, USA, the IPS serves as a vital platform for international cooperation in the study of algae. Every four years, the IPS convenes the esteemed International Phycological Congress, bringing together experts and enthusiasts worldwide to explore cutting-edge developments in algal research.

In celebration of this spirit of collaboration, the Philippines led by the Marine Science Institute of the University of the Philippines-Diliman is hosting the 13th International Phycological Congress from June 8 to 13, 2025, in the picturesque setting of Panglao, Bohol. Situated amidst the stunning landscape of Panglao Island, alongside its counterpart municipality Dauis, Panglao is renowned for its vibrant diving spots and luxurious tourist resorts. The name Panglao, thought to have originated from its former designation Panglawod, meaning “to the open sea”, or perhaps derived from panggaw, a local term for a traditional fishing tool, encapsulates the island’s rich maritime heritage and natural beauty.
