Very lucky to have spent earlier this year 3 months in the forest with the amazing Ngogo chimps (Kibale, Uganda) for my postdoc! @ceec-research.bsky.social here with Penelope’s family 🍃

PostDoc at University of Rennes, France Currently studying multimodal communication in wild chimpanzees 🌿
I compiled a list of 350 #funding opportunities for #postdoctoral research #fellowships: https://docs.google.com/spreadsheets/d/1J2M_tQgoqV4ivpfEClh9qs9f2KQN2O1G3Jpda2aoHfQ/edit?usp=sharing I realized I should share this again after mentioning it to some folks at the #EFP2026
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
From cooperation to conflict: Liran’s keynote explored how chimpanzees and bonobos reveal the evolutionary roots of cooperation, group identity, tolerance, and violence, offering new insights into the social foundations of human behaviour. 🧠🐒 #EFP2026
🧪ETHOLOGY: What happens after an infant kidnapping attempt in a primate society? 🐒🙈🙉🙊 A rare observation in wild geladas revealed that attempts to abduct a newborn triggered social changes. Grooming networks became denser and more reciprocal, while aggression increased: doi.org/10.1111/eth....
Ripple Effects: Social Turmoil Following Infant Kidnapping Attempts in Wild Geladas
Graphical abstract illustrating the social consequences of infant kidnapping in wild geladas (Theropithecus gelada). The study monitors a 28-day period divided into a 14-day pre-kidnapping phase and ...

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
In a decades-long study, researchers have documented what appears to be the first observed “civil war” in wild chimpanzees. The findings demonstrate that shifting social ties alone can fracture a once unified group and ignite sustained, deadly conflict among former allies. https://scim.ag/47QE8Qw
🚨 Our new publication deals with cases of repeated attempts of infant kidnapping in one of our groups of geladas, why could this happen and what consequences on group dynamics?? with @ceec-research.bsky.social 🐒 Open access here:

Already 3 months passed since my PhD thesis defense! I couldn’t be more grateful to my supervisors Elisabetta Palagi and Alban Lemasson, incredible jury members (Josep Call, Mariska Kret, Elodie Briefer, Andrea Ravignani) and all primates who shared the journey with me ❤️ @ceec-research.bsky.social
With a new year comes a new field season for the #APELANG team! Celebrating their first night in the forest 🐵 Welcome to the latest addition to the team @lucapedruzzi.bsky.social 😍 Looking forward to the next 3 years together !
Our new paper on yawn vocalizations in geladas is out on iScience! Happy holidays to you all :) OA here: www.sciencedirect.com/science/arti... @ethos-research.bsky.social @lucapedruzzi.bsky.social @leakeyfoundation.org
Our new publication is out and offers some interesting (and creepy) insights for the management of zoo-housed geladas! Yes, monkeys kidnap infants sometimes! Open access here: doi.org/10.1016/j.ap... @geladasbridges.bsky.social 🐒
Go watch our brand new documentary! 🐒🇪🇹🇮🇹
We are so happy to tell you that finally our documentary about our project🇪🇹 has been released on YouTube. We hope you’ll find some time to watch it, to learn about our adventures and the wonderful work we are doing ❤️ Huge thanks to Alberto Alessi for making this possible! WATCH IT!
New paper out by @lucapedruzzi.bsky.social, Alban Lemasson and collaborators on geladas agression, kidnapping and death 💀 Maybe not the casual reading while having your morning coffee… doi.org/10.1016/j.ap...

🚨New paper alert! 🐵 We compared yawning in geladas vs hamadryas baboons and guess what? Differences in the sociobiology of the two species seem to be reflected in the expression of the behaviour OA here: onlinelibrary.wiley.com/doi/10.1002/... @ethos-research.bsky.social

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
Last week we presented first data from our @geladas_bridges project at the conference of the Italian Society for the study of Animal Behaviour @sie_etologia in Turin! Emotions and prosociality in vocal exchanges of wild geladas… so happy and proud 🐒 @EthosLabo @TheLeakeyFndtn
