Demographic changes in the Sonso community of wild chimpanzees and the occurrence of infanticides.
We plot the total number of adult females in the community and the male:female sex ratio over the last 10 years. Sex ratio indicates the power of the community males to acquire and defend territory relative to the number of females competing for resources within the home range.
