Important information

We hope you enjoyed the meeting!

Last information about Covid spread...

We hope our covid protocol limited COVID spread, but in case you are tested positive, please fill the contact tracing form. Take care, we hope that you will recover quickly!

To promote research studying the risk of COVID-19 spread at large gatherings and find out which factors influence the spread, a research group at the Max Planck Institute for Dynamics and Self-Organization and the University of Lübeck (Viola Priesemann, André Calero Valdez, Jens Friedel, Lilian Kojan and Emil Iftekhar) propose you to fill a survey.


Welcome to ISS 10/Holobiont 3

The first symbiotic relationships were described in the 19th century. Nearly 150 years later, immense research efforts have highlighted that symbiotic relationships are ubiquitous and have particularly important ecological and evolutionary consequences. But considering individuals as holobionts, or ecosystems that combine host and symbiotic entities, is an on-going revolution.

Within this framework, the 10th Congress of the International Symbiosis Society will be held in conjunction with the 3rd edition of the International Conference on Holobionts at the Palais des Congrès of Lyon (France) from July 25 to 29, 2022. This joint congress will provide a unique opportunity to present the most exciting and recent discoveries in the fields of symbiosis and holobiont research.

During this meeting, we will give a special emphasis on symbiosis in the Anthropocene era. Faced with the challenges generated by global upheavals, be they societal, medical, or environmental, it is indeed essential to understand the impact of these changes on symbioses, and also to foresee how symbioses may allow to cope with these challenges in the future of our biosphere.

The program has been designed to cover a wide range of fundamental and applied topics in current symbiotic and holobiotic research. We are delighted to welcome prestigious guest speakers at the forefront of research, working on various types of organisms (e.g., virus, bacteria, protists, invertebrates, plants and humans).

This major international meeting will be held in Lyon, the French capital of gastronomy and wine, a UNESCO World Heritage, and the birthplace of cinema with Lumière brothers.
