Congratulations to post-doctoral fellow Urs Kalbitzer and co-authours (M.L. Bergstrom, S.D. Carnegie, E.C. Wikberg, S. Kawamura, F. A. Campos, K.M. Jack, L.M. Fedigan) on their latest publication: "Female sociality and sexual conflict shape offspring survival in a Neotropical primate" which has been published in the Early Edition of PNAS (Proceedings of the National Academy of Sciences). 

The article examines the relationship between female sociality, offspring survival, and infanticide risk in wild white-faced capuchin monkeys (Cebus capucinus imitator). The researchers analyzed long term data collected in Santa Rosa, Costa Rica and found that infants of more sociable females had a higher survival rate than infants of less social females. This was the case except during times of group instability. The instability caused by alpha male replacements appears to increase the infanticide risk to the infants of these more social and therefore also more central females.
