The first SCAR Biology Symposium was held jointly with IUBS (the International Union of Biological Sciences) in September 1962 and initially was held at irregular intervals. Since 2001, the Biology Symposium has been held regularly every four years, alternating with SCAR’s Antarctic Earth Sciences symposium, ISAES.
The pattern was interrupted in 2021 due to continuing restrictions caused by the COVID-19 pandemic. XIII Biology Symposium was postponed from 2021 to 2023, with the expectation that the four-yearly pattern continues from then.
