Could DNA barcodes help fight the commercial wildlife trade? [warning: graphic image] Jeremy Hance mongabay.com September 08, 2009
A new study in Conservation Genetics uncovered short barcodes of DNA for 25 mammals and reptile species that are threatened by the bushmeat and wildlife trade. These barcodes make it possible for authorities to rapidly identify the species killed for the meat or trade product. "The species in our study are among the most commercially harvested species in South America and Africa. They are often partially prepared by the time they get to urban markets, which can make the species identification impossible," says one of the lead authors, Mitchell Eaton from the University of Colorado. "In this study, we tested the usefulness of molecular barcodes for monitoring bushmeat harvest and trafficking in wildlife products. We have shown that the method effectively and unambiguously identifies a large number of species."
The study, besides being helpful for wildlife authorities, raises new taxonomic questions for a number of species. The authors found that the African Nile crocodile may in fact be two different species—a western and an eastern, while Peter's duiker—a forest antelope—may have enough genetic diversity to be split up into separate subspecies or species, although further studies are needed. The sequences identified in the study will be added to the Barcode of Life Data Systems, an online, open-access library of barcodes for many of the world's species. Citation: Mitchell J.
