Figure 2From: Environmental variation and rivers govern the structure of chimpanzee genetic diversity in a biodiversity hotspot Sample locations of chimpanzees included in the study. Locations spanned Cameroon and eastern Nigeria. Approximate distributions of P. t. ellioti (purple) and P. t. troglodytes (orange) ranges are shown. White circles denote both mtDNA and microsatellite data were available at the location. Black circles denote only mtDNA data was available.Back to article page
