ISTA 9 3/4 - 18-20.102021

ISTA 9 3/4 will take place online Oct 18-20 1-5 pm CET.

The Soil Biodiversity Lab at the University of Neuchâtel is very happy to announce the next ISTA meeting! This will be an online meeting, by zoom. Physical attendance is possible for a limited number of participants at the University of Neuchâtel, Switzerland.

We thank ISOP for supporting the meeting with the Zoom license!

As an extra twist (and considering that virtual meetings are something of a magical feat) it was noticed that the previous meeting was ISTA 9 and the next planned was ISTA 10. ISTA 10 was initially planned for 2020, in line with our habit of holding these meetings every 2 years and alternating between Europe and the rest of the world. Due to the COVID pandemic, ISTA 10 had to be postponed first to 2021 and then to 2020. Thus instead of having to wait 2 year between ISTA 9 and 10 we had a 4 year gap. Hence if we don’t change the name ISTA10 for the one planned in Niagara in 2022, it logically follows that this 2021 online meeting will be ISTA 9 ¾! For sure this will be a magical meeting!

The dates that suit most people are October 18-20 and the time will be in the afternoon. This timing is of course hell for our colleagues in eastern Asia, Australia and New Zealand. So please forgive us for that. We’ll most likely record the meeting and if speakers approve post the talks online.

We aim for 15’ talks (12' presentations and 3' questions) and a longer keynote talks (25' + 5') by a selection of the "next gen" testate amoeba researchers. Posters will be shortly presented and then participants will have a chance to discuss with poster presenters in separate discussion rooms.

Please register here: https://docs.google.com/forms/d/e/1FAIpQLSf3-81myIBwxiG3PQidXwYmMM6hGm1NT9p0wGeUN_3HGtHWEw/viewform

Once this is done you’ll get a link to submit an abstract for a poster or talk if you wish to present one (or more).
