Meet three scientists who said no to Epstein The warning signs included a web search, a mother’s doubts, and inklings of a β€œsexist attitude”

this (good) story is very funny to me because it's like How Did These Top Scientists Avoid Working With Epstein? πŸ€” They Googled Him And Saw He Was A Bad Guy πŸ˜”

Colobus Monkeys in a Multilevel Society Show Frequent Adult Male Same-Sex Sexual Behavior with High Recurrence and Low Constraint

Thrilled to share that our new paper is out today! πŸŽ‰

We report the first description of same-sex sexual behaviour in Rwenzori Angolan colobus monkeys - and find it may play a role in male social bonding within their multilevel societies.

Perfect Valentine’s Day reading β€οΈπŸ’

This paper raises really interesting questions about the role of SSB, particularly in stressful environments. While SSB was once thought of as paradoxical or strange, new work increasingly suggests an important social function for SSB in animals.

Excellent new paper out from the Savolainen lab. They found that SSB expression in primates was more likely in species living in difficult environments, with longer life histories, and those with more complex social systems.

New lab paper! We ran a vervet #foraging #experiment where we created both #scramble and #contest. This evened foraging success, but experiencing more #competition still led to #risk averse #decisions by the monkeys, showing the importance of this variable. www.frontiersin.org/journals/beh...

Excited to share our new paper on the #social #structure of Rwenzori #colobus multi-male, multi-female core units! We found 3 different patterns but close #male #relationships in all that were long lasting! Paper is behind a paywall but contact us if you want a pdf. link.springer.com/article/10.1...

Young chimps play weird with tools and other objects & this can lead to innovation! Moss sponging, doll play, leaf clipping to ask for carrying. If copied and retained, rare kid innovations can contribute to cultural complexity πŸ§ͺπŸ”¬πŸ΅

Lemurs can help save Madagascan forests, but first we need to protect them Climate change, forest fragmentation and hunting threaten lemur populations in Madagascar, and impact the health of mothers and infants.

Great media piece by my PhD student, Colombe Sehenomalala, on state of lemur research & conservation in home country of Madagascar. Did you know lemurs are important seed dispersers? @theconversation.com @anthropologieudem.bsky.social
