Isolation and characterization of twelve microsatellite loci of endangered Ishikawa’s frog (Odorrana ishikawae)

Abstract

Due to an originally small distribution range and over-exploitation of primary forest, Ishikawa’s frog (Odorrana ishikawae) has been steadily declining in number. For effective conservation of this species, a greater amount of genetic information of this species is needed. Here, we isolated and characterized 12 microsatellite loci of O. ishikawae using two different methods. Loci were screened from two populations on the Amami (N = 44) and Okinawa (N = 9) Islands. The total number of alleles per locus ranged from 2 to 30, and the observed heterozygosity ranged from 0 to 0.922. Notably, high F ST values for all examined loci were observed between the two populations. Taken together, our findings suggest that these novel loci will be applicable for conservation genetic studies across varying scales.
