Do Chimpanzees (Pan troglodytes) Spontaneously Take Turns in a Reciprocal Cooperation Task?
Reciprocity is considered to be an explanation for altruism toward nonkin. Although there have been many theoretical studies and reciprocity is arguably prevalent in humans, little experimental work has investigated the proximate mechanism of reciprocity in nonhuman animals. The authors tested whether pairs of chimpanzees (Pan troglodytes) would achieve reciprocal cooperation, that is, whether chimpanzees […]
Space to choose: network analysis of social preferences in a captive chimpanzee community, and implications for management
Abstract Social network analysis (SNA) is rapidly gaining popularity in primatology, but its application to the management of zoo-housed primates has been largely overlooked. Here I use SNA techniques to explore the social structure of chimpanzees (Pan troglodytes) housed in the new “Budongo Trail” exhibit at Edinburgh Zoo, UK. Given that individuals have extensive space […]
