The Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) is the most endangered currently recognized chimpanzee in Africa. There are estimated to be between 3500 and 9000 individuals in Nigeria and Western/Central Cameroon. While there is an increasing body of knowledge on their taxonomy, genetics, morphology, and distribution, relatively little is known about there ecology, behavior, culture, and conservation status - especially when compared to the other chimpanzee subspecies in Africa.
There are only an estimated 3500 - 9000 individuals left in the wild today.
The population genetics of wild chimpanzees in Cameroon and Nigeria suggests a positive role for selection in the evolution of chimpanzee subspecies
Chimpanzee population structure in Cameroon and Nigeria is associated with habitat variation that may be lost under climate change
