Figure 2. Comparison of different genetic diversity estimators: (Na) number of alleles (A); (Ar) allelic richness (B); (Par) private allelic richness (C); and (He) expected heterozygosity (D) from different house sparrow populations.

For Europe –a and USA data from [24]; data for Finland from [58]; data for France from [59]; and data from Brazil and Europe –b where obtained from this study using all six loci (Table 1). Filled circles are introduced populations while open circles are native populations. Not all estimators were available in all the studies.
