Pleased to have been a part of this project, now detailed by Dr. Rosemary Blersch (not on BlueSky) based on work in the McCowan-Vandeleest Laboratory for Biobehavioral Complexity.
Studies often examine effects of clumped resources, we decentralized food provisioning to increase social tolerance.

Food Distribution, But Not Market Forces, Predict Behavioral Social Tolerance in Rhesus Macaques
Decentralizing food resources in rhesus macaques reduced aggression, increased co-feeding and promoted social tolerance, suggesting that distributed resources could enhance group stability and welfar....

Development is lots of 'figuring things out'!
But, how do we understand relationships as infants transition away from play🙃? Is play a precursor to other social behaviors, or is proximity or contact🤗 more reflective of partner choice?

🚨 New paper! 🚨
🐒 White-faced capuchins experience high rates of infanticide.
🐒 Infanticide is costly to female reproduction.
🐒 Do females exhibit the Bruce effect (termination of pregnancy) to reduce these costs?
🐒 Spoiler: Nope!

Excited to share the outcomes of our new paper introducing predictability to group management practices. A challenging endeavor, because management practices often share unreliable cues.
Really happy with how this turned out, possible through lots of support!

Personality has been one of my favorite topics to research. I was thrilled at the opportunity to publish on personality ratings from three species of wild macaques!
Multisite field studies, like this one, are a rarity.
