@article{Wilson2004NewCO, title={New Cases of Intergroup Violence Among Chimpanzees in Gombe National Park, Tanzania}, author={Michael Lawrence Wilson and William Wallauer and Anne E. Pusey}, journal={International Journal of Primatology}, year={2004}, volume={25}, pages={523-549} }
Despite considerable attention to chimpanzee intergroup violence, the number of observed cases remains small. We report 4 cases of intergroup violence that occurred in Gombe National Park, Tanzania, between 1993 and 2002. We observed (3 cases) or inferred (1 case) males from the Kasekela community to attack members of their 2 neighboring communities: Mitumba and Kalande. In 1993, Kasekela males killed and ate a female infant from Mitumba. In 1998, Kasekela males captured 2 infants (sex unknown…

Death of the Alpha: Within‐Community Lethal Violence Among Chimpanzees of the Mahale Mountains National Park
- PsychologyAmerican journal of primatology

The first account of the killing of an incumbent alpha male by a coalition of adult males from the same community is provided; the lethal attack triggered a period of instability in the male hierarchy and was likely an opportunistic attempt to seize alpha status by the third‐ranking male.

Fatal Chimpanzee Attack in Loango National Park, Gabon
- Biology, PsychologyInternational Journal of Primatology
- 2007
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.
Intercommunity interactions and killings in central chimpanzees (Pan troglodytes troglodytes) from Loango National Park, Gabon
- Environmental SciencePrimates; journal of primatology
- 2021
First insights into intercommunity interactions of individuals of a community of central chimpanzees living in the Loango National Park in Gabon suggest that the frequency of lethal attacks at Loango is comparable to that reported for the eastern subspecies and female involvement in inter community interactions mirrors that of the western subspecies.
Causes of death in the Kasekela chimpanzees of Gombe National Park, Tanzania
- Environmental Science, BiologyAmerican journal of primatology

It is found that the most important cause of mortality in the Kasekela community was illness, followed by intraspecific aggression, and most deaths due to illness occurred during epidemics, and the most common category of disease was respiratory.

Lethal intragroup aggression by adult male spider monkeys (Ateles geoffroyi)
- BiologyAmerican journal of primatology
- 2006
Three cases of coalitionary aggression by adult male black‐handed spider monkeys (Ateles geoffroyi) against subadult males within their community on Barro Colorado Island, Panama are reported, which suggests that intense competition among males for access to reproductively viable females may be a contributing factor.
