The Barcode of Life Data System

In recent years, DNA barcoding has emerged as a new way for scientists to identify unique species and protect the Earth's biodiversity. Readers interested in this field of research may want to check out the Barcode of Life Data System (BOLD). Launched in 2005 and currently in its fourth iteration, BOLD describes itself as "an online workbench and database that supports the assembly and use of DNA barcode data [..., as well as] a collaborative hub for the scientific community and a public resource for citizens at large." Visitors can search its public data portal by scientific name, geography, name of the depository holding the specimen, and other fields. For example, a search for "Wisconsin" reveals that over 2,500 specimens representing 800 species have been collected in the state and sequenced. As of this write-up, BOLD contains more than 7.1 million barcodes from roughly 300,000 species. Instructors interested in using BOLD in the classroom should visit the Education Portal, available from the main page. BOLD is led by Paul Hebert, a professor of integrative biology at the University of Guelph and the director of the Center for Biodiversity Genomics (CBG); and by Sujeevan Ratnasingham, CBG's associate director of informatics.
