Abstract
AbstractMicrosatellites have been developed for few amphibian species. However, developing genetic markers for population genetic studies in amphibians is critical because amphibians are declining globally. The tiger salamander,Ambystoma tigrinum, is widespread throughout the United States and includes the endangered subspecies,A. t. stebbinsi. We present primers and amplification conditions for 10 polymorphic microsatellite loci that have produced successful results in three subspecies ofA. tigrinum. Number of alleles per locus ranged from one to 11 and heterozygosity ranged from 0 to 0.815 depending on the subspecies and locus analysed. These markers should prove useful for future studies of genetic diversity and population subdivision.
