  abstract = {{B}ackground: {C}himpanzees ({P}an troglodytes) can be divided into four subspecies. {S}ubstantial phylogenetic evidence suggests that these subspecies can be grouped into two distinct lineages: a western {A}frican group that includes {P}. t. verus and {P}. t. ellioti and a central/eastern {A}frican group that includes {P}. t. troglodytes and {P}. t. schweinfurthii. {T}he geographic division of these two lineages occurs in {C}ameroon, where the rages of {P}. t. ellioti and {P}. t. troglodytes appear to converge at the {S}anaga {R}iver. {R}emarkably, few population genetic studies have included wild chimpanzees from this region. {R}esults: {W}e analyzed microsatellite genotypes of 187 wild, unrelated chimpanzees, and mitochondrial control region sequencing data from 604 chimpanzees. {W}e found that chimpanzees in {C}ameroon and eastern {N}igeria comprise at least two, and likely three populations. {B}oth the mt{DNA} and microsatellite data suggest that there is a primary separation of {P}. t. troglodytes in southern {C}ameroon from {P}. t. ellioti north and west of the {S}anaga {R}iver. {T}hese two populations split similar to 200-250 thousand years ago (kya), but have exchanged one migrant per generation since separating. {I}n addition, {P}. t. ellioti consists of two populations that split from one another similar to 4 kya. {O}ne population is located in the rainforests of western {C}ameroon and eastern {N}igeria, whereas the second population appears to be confined to a savannah-woodland mosaic in central {C}ameroon. {C}onclusions: {O}ur findings suggest that there are as many as three genetically distinct populations of chimpanzees in {C}ameroon and eastern {N}igeria. {P}. t. troglodytes in southern {C}ameroon comprises one population that is separated from two populations of {P}. t. ellioti in western and central {C}ameroon, respectively. {P}. t. ellioti and {P}. t. troglodytes appear to be characterized by a pattern of isolation-with-migration, and thus, we propose that neutral processes alone can not explain the differentiation of {P}. t. ellioti and {P}. t. troglodytes.},
