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...

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…

🚨 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

🚨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/...

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!

Wild gelada monkeys detect emotional and prosocial cues in vocal exchanges during aggression Recognizing vocal behaviours intended to benefit others is a crucial yet understudied social skill. Primates with rich vocal repertoires and complex societies are excellent models to track the evoluti...

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

Life on the field 🐒

Yawn Contagion and Modality‐Matching in the Female‐Bonded Society of Geladas (Theropithecus gelada) Behavioral contagion is widespread in primates, with yawn contagion (YC) being a well-known example. Often associated with ingroup dynamics and synchronization, the possible functions and evolutionar...

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:

It might look like I’m posing but I’m actually desperate trying to identify the too many geladas in front of me 😅

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:

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

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

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

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!
