Identification and characterization of nine polymorphic microsatellite loci in the North American pika, Ochotona princeps

Nine polymorphic microsatellite loci were developed for the North American pika ( Ochotona princeps ) from di‐ and tetranucleotide repeat‐enriched genomic libraries. Polymorphism was assessed for 165 individuals from eight geographical locations in the western United States. All loci were polymorphic. The number of alleles per locus ranged from three to 14, with observed heterozygosity between 0.189 and 0.822. All loci were in Hardy–Weinberg equilibrium (< 0.05). Regional differences were evident with unique alleles at multiple loci in six of eight populations.
