Dear colleagues, I have the pleasure to announce you the availability of six speakers for our online meeting on the*8th of December, 22-24 Paris CET*. So please don't forget that this means early afternoon for Americans (13-15 San Francisco, 15-17 Chicago, 17-19 Buenos Aires), late  in the day/night for people in Europe (22-24 Paris CET) and early the next day (9th of December) for scientist from the Asia region (Shanghai 5-7 ;Tokyo 6-8). You will be able to listen before the meeting to five 20 min talks on youtube (the links will come next Wednesday), and we will have one 180 seconds live talk. Please find the talk titles below, I hope that this will motivate many to participate. The survey of our group is also still open and should take you less than ten minutes to complete.  It would be great if we could have a more complete view of your IUFRO group. Your participation would greatly help us make more effective and engaging plans for future activities.
