DNA barcodes of fish of the Scotia Sea, Antarctica indicate priority groups for taxonomic and systematics focus

摘要: We analysed cytochrome oxidase I (COI) barcodes for 35 putative fish species collected in the Scotia Sea, and compared resultant molecular data with field-based morphological identifications, additional sequence obtained from GenBank Barcode of Life Data System (BOLD). There was high congruence between classification, COI provided effective species-level discrimination nearly all species. No effect geographic sampling observed variation. For two families, including Liparidae Zoarcidae, which field identification unable to resolve taxonomy, DNA barcoding revealed significant divergence. However, dataset lacked sufficient sensitivity resolving within Bathydraco Artedidraco genera. Analysis b these genera also failed taxonomic identity. The are discussed relation emergent priorities studies. emphasize utility providing a valuable framework fundamental population studies through assigning life history stages or other morphologically ambiguous samples parental
