Universal primers  and newly designed species-specific primers (underlined) used for amplifying Ursidae mt genomes. Locations of new primers are indicated in brackets and correspond to nucleotide numbers from the harbor seal sequence (Accession No. X63726). Eleven mtDNA fragments (mtDNA1-11) covering the entire mt genome are labeled as described in Delisle and Strobeck (2002) .
