invite presenters from complementary sessions
organizers submit an abstract to the complementary poster session to be on the program and transfer to fill in for last-minute drop-outs
hold a panel or round table discussion in the empty time slot
Build a sense of community
Hold regular virtual meetings with authors (see Plan a symposium action list plus timeline, incl. template meeting agendas)
Encourage collaborative manuscripts co-authored by the presenters invited to your symposium (Perspective or Review article)
Encourage or host writing groups to help with timely manuscript submission
Be transparent about presenter expectations
Communicate expectations and timelines (see Plan a symposium action list plus timeline, including template communications)
Communicate publication expectations and author support resources (such as ICB author support webpage)
Build resilience
Recruit a co-presenter. Encourage speakers to work closely with their co-presenters so they are able to replace the presenter if needed
Have back-up speakers on stand-by. Invite back-up speakers by recruiting presenters to your symposium's complementary oral sessions; consider designating back-up speakers in advance (ask complementary speakers if they would be willing to to moved to a symposium slot if need arises)
Pro: complementary talks are already in the conference program; it's easier on the presenter to turn a complementary talk into a symposium talk than upgrading a poster to a talk
Con: moving a speaker from a complementary session to a symposium creates a gap in the complementary session schedule (let that be SICB's worry)
Be the back-up, not the main act. Plan a presentation by the symposium organizers as back up instead of giving yourselves a time slot in the original line-up; submit the abstract to the complementary poster session to ensure that the presentation is already in the schedule
Pro: moving a poster presentation to the symposium does not create a gap in the complementary session schedule
Con: requires preparing a poster and a talk; to reduce workload, submit a complementary talk instead
You are not alone! Contact SICB and ICB right away
SICB and ICB have seen it all and are happy to help brainstorm and execute ideas and workarounds to fit your timeline and urgency
Contact the SICB program officer (ProgramOfficer@sicb.org) and cc the ICB managing editor (icbjournal@sicb.org) to communicate that a speaker has dropped out and to ask for help (if desired), and again when you know the name of the replacement speaker and their presentation title
Contact your first choice for back-up speaker
See above "Build resilience": build a pool of potential back-up speakers, for example by inviting presenters to complementary sessions
