Table 1 Models to explain the partitioning of chimpanzee genetic variability across the study region, and associated predictions

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

Predictions Riverine barriers Ecological variation
Diversity of neutral alleles Highest on opposite banks of Sanaga and Mbam Rivers Significant correlations between the distribution of allelic diversity and variation in one or more environmental variables.
Population divergence (T MRCA ) Broad spectrum of time intervals Broad spectrum of time intervals
Barriers to gene flow are located At the Sanaga, with highest resistance at the Sanaga Delta and decreasing towards headwaters At or near ecotone boundaries, but not at adjacent Guinean-Congolian rainforest boundary in western Cameroon
Population history includes Demographic stability, other scenarios possible Demographic stability, other scenarios possible
