The aim of the study was to describe the reproductive biology of wild chimpanzees (Pan troglodytes schweinfurthi) and to relate this to aspects of their ecology and social organisation. Within this general framework the specific aims were: (a) To determine the reproductive potential of female chimpanzees and to assess the limits this places on species' reproduction; (b) To examine the adaptive significance of female reproductive physiology in terms of optimal reproductive success; (c) To examine environmental constraints on reproduction; (d) To describe copulatory behaviour and the nature of the three mating patterns shown by wild chimpanzees, and to assess the adaptive significance of the flexible mating system; (e) To relate reproductive behaviour to social organisation in an attempt to assess the role of sexual selection in the evolution of chimpanzee social behaviour and structure.
