چکیده

Although three species of the genus Macrourus are recognized in the Southern Ocean, DNA sequencing of the mitochondrial COI gene revealed four well-supported clades. These barcode data suggest the presence of an undescribed species, a conclusion supported by meristic and morphometric examination of specimens.

Cryptic speciation and the circumpolarity debate: A case study on endemic Southern Ocean octopuses using the COI barcode of life

Three hundred and fifty specimens of the endemic Southern Ocean octopus genus Pareledone, were sequenced for the barcoding gene COI. Geographic coverage comprised the South Shetland Islands, the Ross Sea, Adélie Land, George V Land, the Weddell Sea, under the site of the former Larsen B ice shelf, Prydz Bay, the South Orkney Islands and the Amundsen Sea. The greatest number of specimens was cap...

Appraisal of the entire mitochondrial genome for DNA barcoding in birds

DNA barcoding based on a standardized region of 648 base pairs of mitochondrial DNAsequences from Cytochrome C Oxidase 1 (COX1) is proposed for animal species identification.Recent studies suggested that DNA barcoding has been effective for identifying 94% of birdspecies. The proposed threshold of 10 times the average intraspecific variation could be used forthe identification and delimitation ...
