Non-genetic maternal effects shape individual differences in cortisol phenotypes in wild chimpanzees

P. J. Tkaczynski, F. Mafessoni, C. Girard-Buttoz, L. Samuni, C. Y. Ackermann, P. Fedurek, C. Gomes, C. Hobaiter, T. Lohrich, V. Manin, A. Preis, P. Vale, E. G. Wessling, L. Wittiger, Z. Zommers, , C. Crockford

The paper examines maternal effects on cortisol phenotypes in wild chimpanzees, finding maternal influence explains 10% of variation, while genetic factors are not distinguishable from zero.

Long-term repeatability in social behaviours suggests stable social phenotypes in wild chimpanzees

P. J. Tkaczynski, A. Mielke, L. Samuni, A. Preis, R. Wittig, C. Crockford

This study shows that social behaviors in wild chimpanzees remain stable over 20 years, suggesting long-term social phenotypes are consistent despite environmental and demographic changes.
