Representation of confidence in CAM assignments for georeferenced chimpanzee samples. The green circles represent 100 point estimates drawn randomly from the set of all possible locations weighted according to their probability. Stars represent the median point coordinate estimate for each georeferenced sample. The concentration of these 100 circles in any given area is a guide to the probability that the sample arose from that area, where tighter concentrations of circles indicate higher confidence in the median point estimate. The top panel shows a georeferenced sample (ISFR001) with estimated CAM origins near its actual location of origin, along with a high concentration of circles near its location origin. The bottom panel shows a georeferenced sample with estimated CAM origins also near its actual sampling location (MANB014), but with more dispersed coordinate point estimates.
