摘要

At the U.S. EPA, several projects in the Office of Research and Development have been investigating the use of DNA barcoding for identifying various aquatic organisms to species. One of the main areas of research is in determining the utility of DNA barcoding for environmental bioassessment - evaluating the environmental health and condition of a site based on the organisms found living there. Standard bioassessment relies on identification of biota, typically benthic invertebrates, using morphological characters. These morphological IDs are done by highly trained taxonomists, which can take many months or even a year to complete. Our work at EPA, along with collaborators outside the agency, seeks to capitalize on the potential speed and cost savings associated with identifying these benthic organisms through DNA barcode data.
