Play-solicitation gestures in chimpanzees in the wild: flexible adjustment to social circumstances and individual matrices [PDF]
Royal Society Open Science, 2016 Social play is a frequent behaviour in great apes and involves sophisticated forms of communicative exchange. While it is well established that great apes test and practise the majority of their gestural signals during play interactions, the influence of

Estimation of chimpanzee age based on DNA methylation
Scientific Reports, 2018 In wild animal conservation, knowing the age of an individual animal is extremely beneficial. However, estimating the age is difficult for many species. Recently, epigenetics-based methods of estimating age have been reported.
