Fig. 3From: Evidence for genetic variation in Natterer’s bats (Myotis nattereri) across three regions in Germany but no evidence for co-variation with their associated astrovirusesIsolation-by-distance analysis for data from 19 nuclear microsatellite loci from Myotis nattereri within Germany. The graph displays the significant correlation between genetic differentiation and ln of geographical distance (in km) for all pairwise comparisons of colonies. Genetic distance was measured as Rousset’s F ST/(1-F ST) and the relationship with geographic distance was tested using a Mantel test with 1000 permutations. The line represents a linear regression of this relationship and only serves an illustrative purposeBack to article page
