These sequences combine simple (grunts) with more derived vocalizations (moans, wobbles), facial expressions (lip-smacking, lip-flips), gestures (rear presenting), and physical contact (grooming, genital sniffing, etc.). (3/3)
Geladas For Cooperation

Research project on the social behaviour of geladas in Ethiopia (PI: Elisabetta Palagi; co-PI: Bezawork Afework). Follow our scientific and social journey!
Who initiates these conciliatory sequences? Male aggressors 👹 are most likely to produce them, potentially helping to repair relationships and maintain group cohesion after conflicts. (2/3)
New paper🚨 Wild geladas exchange multimodal signal sequences after conflicts, with complexity increasing according to the aggressor-victim social, genetic, and hierarchical relationship! (1/3) Big efforts for this one 🙌🏽 @geladasbridges.bsky.social @ceec-research.bsky.social Read it OA here:

It was a great week in Montpellier at #EFP2026 and I also had the chance to present my results on the communicative sequences used by geladas to solve their ingroup conflicts… stay tuned 🤝🏽🐒 @efp2026.bsky.social @ceec-research.bsky.social @geladasbridges.bsky.social
Very grateful to receive the Marconato–Marchesini Prize for research on evolutionary biology and species conservation for my PhD thesis by the Istituto Veneto di Scienze, Lettere ed Arti 🐒 (in a wonderful venue in Venice!) @geladasbridges.bsky.social @ceec-research.bsky.social
New paper 🚨 We analyzed 2500+ yawns from nearly 200 geladas across wild and captive groups, and found that their unique multimodal (“loud”) yawns may signal heightened emotional arousal! OA 📄 www.sciencedirect.com/science/arti... @asab.org @ceec-research.bsky.social @geladasbridges.bsky.social

Luca Pedruzzi@lucapedruzzi.bsky.social · last yr.🚨New paper alert! 🐵 We compared yawning in geladas vs hamadryas baboons and guess what?

With great joy and surprise, we received more donations, and we wasted no time! Today, we could donate school supplies to the 76 students of Godo Elem. School, where many of our friends and "field assistants" study. A perfect way to end an unforgettable year in Ethiopia❤️

It might look like I’m posing but I’m actually desperate trying to identify the too many geladas in front of me 😅 @geladas_bridges #fieldlife
We finally delivered the first part of the materials for the schools of Debre Libanos purchased thanks to the donations of many of you 📚It was a day filled with joy and strong emotions. Your generosity and trust mean a lot to us! For more info and pics, see our Ig/Fb pages
We are back on the field🐒 already facing the many challenges of field life! But as geladas do… we also quickly adapt! @TheLeakeyFndtn @Dip_Bio_Unipi @EthosLabo
