Characterization of seven polymorphic microsatellite loci in the Baja California endemic black-tailed brush lizard Urosaurus nigricaudus

Seven microsatellite loci were developed for the Baja California endemic black-tailed brush lizard Urosaurus nigricaudus, using an enriched genomic DNA library. All loci were polymorphic and overall presented high levels of variation. Number of alleles ranged from five to 16 (average 12.14), and observed heterozygosities from 0.535 to 0.923 (average 0.752). Cross-species amplification was successful and polymorphism was detected for all the loci using the congeners Urosaurus lahtelai and Urosaurus ornatus. These markers will be useful to study fragmented populations of U. nigricaudus on agricultural landscape of the Baja California Peninsula.
