Isolation and characterization of eight polymorphic microsatellite loci in the endangered Hawaiian tree snail, Achatinella sowerbyana

Achatinella is a genus of highly endangered native Hawaiian tree snails. Eight polymorphic microsatellite markers were isolated for one species, Achatinella sowerbyana, to be used in assessing remaining genetic diversity and gene flow in the often small and isolated populations. All loci amplified consistently in every individual tested. The number of alleles per locus in a sample of 40 individuals varied from three to 13, and the observed heterozygosity ranged from 0.308 to 0.846. These markers will be used to assist in the development of conservation and management plans.
