High within-population mitochondrial DNA variation due to microvicariance and population mixing in the land snail Euhadra quaesita (Pulmonata: Bradybaenidae).

Abstract excerpt

A high level of geographical variation at an exceptionally fine scale was detected in the mitochondrial 16S ribosomal RNA genes of a land snail species Euhadra quaesita from the Kanto region of Japan. In total, 50 haplotypes were detected from 27 populations, with most sample sites possessing private alleles. In some individual populations the different haplotypes do not fall as a monophyletic group, so that some...
