From: Female bonobos show social swelling by synchronizing their maximum swelling and increasing bonding

Swelling synchronisation network based on 5 years of data (2018–2022) obtained via freeware Gephi 0.9.7. The nodes are females (grey round circles), and edges show synchronization between females on the maximum swelling phase. In particular, directional edges go from the synchronizing female (follower) to the female eliciting synchronization (trigger). Synchronization occurred within 3 days.
