Chimpanzee Velu: the wild chimpanzee who passed away at the estimated age of 58

Paternity and relatedness in wild chimpanzee communities.

The genetic structure of three contiguous wild chimpanzee communities in West Africa was examined to determine the extent to which the community, the mixed-sex social unit of chimpanzees, represents a closed reproductive unit. An analysis of paternity for 41 offspring resulted in 34 cases of paternity assignment to an adult male belonging to the same community. Among the 14 offspring for which ...

Recent Developments in the Study of Wild Chimpanzee Behavior

Two generations of researchers have followed Goodall and Nishida into the field. As a result, chimpanzees are now one of the best and most widely studied of nonhuman primates. Long-term field research has been conducted at six sites by several researchers spanning 42 years (Fig. 1). Shorter field studies have also been carried out in some areas.9–11 With this extensive body of research, one mig...

Phylogenetic analysis of a new chimpanzee lentivirus SIVcpz-gab2 from a wild-captured chimpanzee from Gabon.

OF A TOTAL OF 50 chimpanzees wild-captured in different O areas of the tropical iain forest in Gabon, two were found to be positive for HIV-1 antibodies.’ From one chimpanzee a lentivirus, sIv,z,ab, was isolated. As a result of virological and molecular studies it was classified as an HIV-l-related nonhuman Subsequently, another chimpanzee lentivhs, SIVEpz-mo has been isolated from a wild-captu...

DNA recovery from wild chimpanzee tools

Most of our knowledge of wild chimpanzee behaviour stems from fewer than 10 long-term field sites. This bias limits studies to a potentially unrepresentative set of communities known to show great behavioural diversity on small geographic scales. Here, we introduce a new genetic approach to bridge the gap between behavioural material evidence in unhabituated chimpanzees and genetic advances in ...
