Association Patterns Among Wild Chimpanzees (Pan Troglodytes Schweinfurthii) Reflect Sex Differences in Cooperation
(Springer Verlag, 2008)Theory predicts that frequent dyadic association should promote cooperation through kin selection or social tolerance. Here we test the hypothesis that sex differences in the strength and stability of association preferences ... -
Comparative Feeding Ecology of Two Chimpanzee Communities in Kibale National Park (Uganda)
(Springer Verlag, 2011)Several recent studies have documented considerable intraspecific and intrapopulation ecological variation in primates. However, we generally lack an understanding of how such variability may be linked to concomitant ... -
Economic Profitability of Social Predation Among Wild Chimpanzees: Individual Variation Promotes Cooperation
(Elsevier, 2008)Social predation (hunting in groups) presents a collective action problem. If nonhunters can obtain meat following a kill, it is unclear why an individual would choose to incur hunting costs.We explored this question using ... -
A Geometric Morphometric Analysis of Heterochrony in the Cranium of Chimpanzees and Bonobos
(Elsevier, 2007)Despite several decades of research, there remains a lack of consensus on the extent to which bonobos are paedomorphic (juvenilized) chimpanzees in terms of cranial morphology. This study reexamines the issue by comparing ... -
Immigration Costs for Female Chimpanzees and Male Protection as an Immigrant Counterstrategy to Intrasexual Aggression
(Elsevier, 2008)In chimpanzees, Pan troglodytes, females transfer from their natal group shortly after sexual maturity to permanently join another group. A conflict of interest exists between female and male residents over the immigration ... -

(Elsevier, 2010)The meat-for-sex hypothesis posits that male chimpanzees (Pan troglodytes) trade meat with estrous females in exchange for short-term mating access. This notion is widely cited in the anthropological literature and has ...
