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! 🐒🇪🇹🇮🇹

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...

Presenting 🐒 at the XXVIII International Congress of Ethology @behaviour2025.bsky.social in Kolkata, India 🇮🇳 @geladasbridges.bsky.social @ethos-research.bsky.social

Presenting our research on gelada flexible communication and emotion recognition during post-conflict interactions at #Behaviour2025 in Kolkata (India)! 🐒 @geladasbridges.bsky.social @ethos-research.bsky.social @behaviour2025.bsky.social

🚨 New paper out! We report encounters between wild geladas and free-roaming dogs in an unprotected area in Ethiopia, highlighting the behavioral adaptability of our amazing geladas! @ethos-research.bsky.social @leakeyfoundation.org Free to read here: doi.org/10.1016/j.ge...

🚨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

Un article de vulgarisation dans The Conversation sur notre dernière recherche! @ethos-research.bsky.social 🐒

Mutual gaze and facial mimicry as drivers of shared engagement in macaque play fighting @lucapedruzzi.bsky.social et al. #OpenAccess doi.org/10.1016/j.an...

🚨Our study on mutual gaze and facial mimicry in rhesus macaques and their possible link to joint commitment is out!! :) doi.org/10.1016/j.an...

New paper alert! 🚨 Mutual gaze and facial mimicry as drivers of shared engagement in macaque play fighting! A study lead by our own @lucapedruzzi.bsky.social, in collaboration with Alban Lemasson, Elisabetta Palagi and many others! www.sciencedirect.com/science/arti...

Check out this video on our new research! 🔊🐒 @lucapedruzzi.bsky.social @ethos-research.bsky.social journals.plos.org/plosone/arti...

It’s finally out!! Our new study shows that wild geladas seem to recognize prosocial vocal affiliation to victims of aggression! A key insight into the evolution of empathy in primates 🔊🐒 @geladasbridges.bsky.social @ethos-research.bsky.social journals.plos.org/plosone/arti...

Life on the field 🐒

Amazing end of the year! 🚨New publication 🚨Our new paper on multimodality in yawn contagion and on the centrality of female-female mirror responses in geladas is finally out! 🐒 free on the American Journal of Primatology onlinelibrary.wiley.com/doi/full/10....

🚨New paper! We found that in rhesus macaques spontaneous triadic affiliation after conflicts is common, increases with the victim-bystander bond and victim distress signals. This challenges traditional despotic-tolerant dichotomies🐒 free to read here: www.sciencedirect.com/science/arti...

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

Last week I had the great opportunity of presenting the work we are doing at the @EFP_2024 in Lausanne #EFP2024 !yawn vocalizations in geladas, facial mimicry and mutual gaze in joint play in rhesus macaques… and more 🐒

🚨 New paper on rhesus macaque play fighting! 🐒 Discover how rapid facial mimicry in this despotic species is influenced by rank and linked to the emotional arousal of playmates! 🎭📊 very proud of this @bettapalagi @EthosLabo Open access here: link.springer.com/article/10.100…

New paper! 🔊🐒 Did you know that apart from humans geladas are the only (known) mammal producing specific vocalizations while yawning? Through a playback experiment we discovered their possible function @bettapalagi @EthosLabo A Lemasson @M_Francesconi nature.com/articles/s4159…

Not only #primates! Our new article on social play and affiliation in cattle is (finally!) out!🐮 We investigated whether fluctuations in the expression of social behaviours might relate to the animals' internal state! @bettapalagi#animalwelfare link.springer.com/article/10.100…

Just come back from a preliminary mobility to Ethiopia for our collab. project between @Unipisa and @AddisAbabaUnive ! A lot of bureaucratic stuff… but also lots of amazing geladas in amazing landscapes! Thanks to the PI @bettapalagi and to Dr. Bezawork Afework!

Just finished a data collection for my PhD on the gelada colony at Rheine NaturZoo (n=106, the largest in world zoos!😱) it was amazing and I’m very excited (and nervous about identification) to analyze all the video and acoustic data collected! @bettapalagi @Unipisa @EthosLabo

Our first study on the social behaviour of cattle in extensive breeding conditions is out on Applied Animal Behaviour Science! @bettapalagi These overlooked wonderful animals have very interesting social dynamics! @ElsevierConnect Free at the link below authors.elsevier.com/c/1gbP0cF2OoinG

It has already passed a month since I started my PhD with @Unipisa and @UnivRennes1 (@EthosLabo)! For the next three years I will work with my two supervisors @bettapalagi and Alban Lemasson to study empathy-related processes in monkeys! Wish me good luck 😬

I’ve been working for some months now at the Giardino Zoologico di Pistoia as guide/educator for visitors during weekends, a great opportunity to talk about the importance of zoos in Conservation & about Animal behaviour (& to work with wonderful animals)!! @EAZAFund

Talking again about our study on yawn contagion in mangabeys at the XXXIX meeting of the Italian Ethological Society! The study:#SIE_Padova2022 @bettapalagi @VeronicaMaglie2 @AychetJuliette @EthosLabo @Unipisa @ortobotanicopd @UnivRennes1 @DiBio_UniPD nature.com/articles/s4159…
