Feeding chimps can also increase their population density by causing them to cluster around human camps, thus causing more competition between them. The combined observational and genetic evidence suggest an intercommunity attack on an adult male chimpanzee at a new research site in Loango National Park, Gabon, adding to the growing evidence that intercommunity killings are a rare but widespread phenomenon among chimpanzees and not an artifact of human provisioning or habituation. Many of the researchers, including Dave Morgan, a research fellow with the Lester E.
