FIG. 1 in The systematics of Pyrenean and Cantabrian Cochlostoma (Gastropoda, Cyclophoroidea) revisited

FIG. 1. Genetic variability in Pyrenean and Cantabrian Cochlostoma. For each population sampled, the number of polymorphic loci (among the 16 examined) is given inside the circle, NÄ is the average number of alleles per locus in the population, H the observed heterozygosity. The grid on the map is of UTM squares.
