TL;DR: It is found that males were the most frequent attackers and victims; most killings involved intercommunity attacks; and attackers greatly outnumbered their victims (median 8:1 ratio).
Journal ArticleDOI
Meat sharing among the Gombe chimpanzees: harassment and reciprocal exchange
TL;DR: It is concluded that the pattern of meat sharing among the Gombe chimpanzees is largely explained by the sharing-under-pressure hypothesis, while the significance of reciprocal exchange remains unclear.
Journal ArticleDOI
Fitness benefits of coalitionary aggression in male chimpanzees
Ian C. Gilby,Lauren J. N. Brent,Emily E. Wroblewski,Rebecca S. Rudicell,Beatrice H. Hahn,Jane Goodall,Anne E. Pusey +6 more
TL;DR: It is found that coalitionary aggression increased a male’s chances of siring offspring, compared to other males of similar dominance rank, and ascending in rank, a correlate of future reproductive output, which is a significant step forward in knowledge of the adaptive value of social intelligence.
Journal ArticleDOI
Core area quality is associated with variance in reproductive success among female chimpanzees at Kibale National Park
TL;DR: The results suggest that superior access to food may have enabled some community females to reproduce more successfully than others, and it is proposed that the intensity of selection on intrasexual competition may be similar between the sexes.
Journal ArticleDOI
Association Patterns Among Wild Chimpanzees (Pan Troglodytes Schweinfurthii) Reflect Sex Differences in Cooperation
Ian C. Gilby,Richard W. Wrangham +1 more
TL;DR: It is found that male–male dyads had significantly stronger association indices than female–female dyads, and when comparing periods with different alpha males, changes in association strength were more frequent among males.
