ABBI/FISH-BOL meeting, Buenos Aires, March 2007 Reactions to Barcoding: 2004 From ecologists and other users: “This is what we need! How soon can we get started?” From ecologists and other users: “This is what we need! How soon can we get started?” From traditional taxonomists: “Species should be based on lots of characters, not just barcodes” From traditional taxonomists: “Species should be based on lots of characters, not just barcodes” From forward-looking taxonomists: “Using molecular data as species diagnostics isn’t new, but standardization and broad implementation are great!” From forward-looking taxonomists: “Using molecular data as species diagnostics isn’t new, but standardization and broad implementation are great!” From barcoding practitioners: “I had my doubts at the beginning, but it really works as a tool for identification (96% accurate in a recent mollusc paper) and it is at least as good as traditional approaches to discovering new species.” From barcoding practitioners: “I had my doubts at the beginning, but it really works as a tool for identification (96% accurate in a recent mollusc paper) and it is at least as good as traditional approaches to discovering new species.”
