Molecular characterization of an opossum Didelphis albiventris (Marsupialia: Didelphidae) population in an urban fragment of the Brazilian Atlantic rainforest and support to species barcode identification.
We  made a molecular study of 40 opossums, Didelphis albiventris, from an  urban fragment of the Atlantic Rainforest in southeastern Brazil, analyzing a  653-bp sequence of cytochrome c oxidase, subunit I. We found three close  connected haplotypes, with low nucleotide diversity and a haplotype diversity  of 59.1% and confirmed sympatry between D. albiventris and D. aurita in  this region. The clear phylogenetic separation shows the appropriateness of DNA  barcode identification methodology for effectively discriminating between these  opossum species.
