Environmental variation and rivers govern the structure of chimpanzee genetic diversity in a biodiversity hotspot

Table 3 Percent of genetic variation within chimpanzee populations explained by GDM ^a

^aIn order to examine genetic diversity within populations, only microsatellite data (F _ST) was used.
^bSub-groupings of chimpanzee populations correspond to distinct genetic populations as determined by Mitchell et al. [23]. The P. t. troglodytes group was included in both the two- and three-population model, as only the P. t. ellioti group is sub-divided in the three-population model.
^cModel includes only geographic distance between sample locations as a predictor variable.
^dModel only includes environmental data layers as predictor variables.
^eEntries are blank because geographic distance was not a significant contributor to the final model.
^fA least cost path layer for the Mbam River was included when running the P. t. ellioti two-population model, but as it was not a significant contributor, was not included in this table.
