  • While I await a post-event summary for the 21st symposium, time - and chironomid research - marches on. Djuradj Milošević joyfully announces that plans are in the works for the 22nd International Symposium on Chironomidae, which will take place in Niš, Serbia, from June 17 to June 19, 2024. The venue will be the University of Niš, Serbia. Per Dr. Milošević : "Leaning on a 60-year tradition of the International Symposium of Chironomidae, the goal is to, yet again, bring scientists from around the world together, share our knowledge, exchange the brightest new ideas, and have fruitful scientific discussions about chironomids while having a good time. To achieve this, ISC22 will devote special attention to young researchers. With the desire to attract as many fresh faces as possible, the main event will be preceded by a three-day series of workshops (June 14 to June 16) covering morphological and molecular identification, chironomids as models organisms in ecotoxicological studies, methods in paleolimnology, as well as numerical ecology in R. Committed to overcoming the boundaries between approaches in chironomids studies, we look forward to welcoming interdisciplinary and transdisciplinary research as well. " (added Apr 2023)
