Quantitative estimates of glacial refugia for chimpanzees ( Pan troglodytes ) since the Last Interglacial (120,000 BP)
Paleoclimate reconstructions have enhanced our understanding of how past climates have shaped present‐day biodiversity. We hypothesize that the geographic extent of Pleistocene forest refugia and suitable habitat fluctuated significantly in time during the late Quaternary for chimpanzees ( Pan troglodytes ). Using bioclimatic variables representing monthly temperature and precipitation estimates, past human population density data, and an extensi…

Audience effects, but not environmental influences, explain variation in gorilla close distance vocalizations—A test of the acoustic adaptation hypothesis
Close distance vocalizations are an integral part of primate vocal communication. They exhibit large acoustic variation which has been suggested to constitute flexible responses to the highly variable social setting of group living animals. However, a recent study suggested that acoustic variation in close distance calls of baboons may also arise from acoustic adaptations to environmental factors in order to counteract sound degradation. We teste…
An experimental study of nettle feeding in captive gorillas
Mountain gorillas ( Gorilla beringei beringei ) in Karisoke, Rwanda, feed on the stinging nettle Laportea alatipes by means of elaborate processing skills. Byrne [e.g. Philosophical Transactions of the Royal Society of London, Series B, Biological Sciences 358:529–536, 2003] has claimed that individuals acquire these skills by means of the so‐called program‐level imitation, in which the overall sequence of problem‐solving steps (not the precise a…
