Baboon fertility and social status
Article Abstract:
A proposed model of reproductive costs has certain discrepancies regarding the effect of high status on the fertility rate and the association of dominance with reproductive success. Of 133 adult female baboons in two wild-foraging groups, there is only one case of lifetime infertility and this behaviour is not due to high rank. The data do not provide substantial information by which occurrences of lifetime infertility or its relationship to social status differ remarkably among groups or populations.

Cultures in chimpanzees
Article Abstract:
A study of information from seven chimpanzee communities has revealed 39 different behaviour patterns that are widely seen in some communities but are not present in others. In these cases, ecological explanations have been dismissed. It is clear that a complex mix of imitation, other types of social learning and individual learning has developed in chimpanzee communities. These behaviour patterns have previously not been recognized in non-human species.

Reproductive constraints on aggressive competition in female baboons
Article Abstract:
A study of the social interactions of female baboons in Gombe National Park, Tanzania, reveals that females of higher social rank are dominant during feeding, fertility and reproduction. The high-ranking female baboons also exhibit short interbirth intervals, early maturation of offsprings and a higher level of infant survival. However, these baboons are more susceptible to miscarriage and reduced fertility than low-rank females.
