Flexibility and persistence of chimpanzee (Pan troglodytes) foraging behavior in a captive environment
As a result of environmental variability, animals may be confronted with uncertainty surrounding the presence of, or accessibility to, food resources at a given location or time. While individuals can rely on personal experience to manage this variability, the behavior of members of an individual’s social group can also provide information regarding the availability or […]
Ecology of culture: do environmental factors influence foraging tool use in wild chimpanzees, Pan troglodytes verus?
Geographical variation in behaviour may be best explained in terms of culture if ecological and genetic explanations can be excluded. However, ecological conditions and genetic predispositions may in turn also affect cultural processes. We examined the influence of environmental factors on foraging tool use among chimpanzees at the Seringbara study site in the Nimba Mountains, […]
Sex differences in tool use acquisition in bonobos (Pan paniscus)
All the great ape species are known tool users in both the wild and captivity, although there is great variation in ability and behavioral repertoire. Differences in tool use acquisition between chimpanzees and gorillas have been attributed to differing levels of social tolerance as a result of differences in social structure. Chimpanzees also show sex […]
