Dear colleagues, We would like to invite you to our upcoming online "Bring-Your-Own-Fluid" (BYOF) seminar organized by the Social Transfer Network, an ESEB-funded Special Topic Network. The next online seminar will take place on September 17th at 15:00 UK time (16h in Europe, 10am in New York, 07am in Los Angeles, etc.). BYOF refers to either the social fluid you might study or your cup of coffee or tea on your desk. Our intention with these seminars is to build an interdisciplinary community on the topic of socially transferred materials, to learn from one another and to advance research across the study of social transfers. In this seminar series, we have three exciting flash talks, about 7 min each + Q&A, followed by discussion. Our speakers for this seminar are: Sinead English & Joshua Benoit: Milk in utero - social fluid transfer in pregnant flies and cockroaches Dillan Saunders: Variation in maternal provisioning as a driver of changes in early development Arthur Matte: The origins and molecular evolution of sperm We expect the meeting to take approximately 1 hour.
