abstract = {This study aims to test whether genetic structure of Antarctic krill (Euphasia superba) samples corresponds to separate geographic regions. The genetic diversity and haplotype network was analysed with two different datasets. The first dataset has 942 base pairs of the mitochondrial genes cytochrome c oxidase subunit I (COI) and NADN dehydrogenase subunit I (ND1) from 105 individuals of krill sampled from seven localities within fishery management areas around Atlantic sector of the Southern Ocean during two different years. The second is the COI sequences from the first dataset combined with COI data from Genbank, in total 456 base pairs for 545 individuals. The intermixed starburst structures of the parsimonious haplotype networks indicate lack of genetic structure over the sampled geographic area and the time period. The haplotype diversity is high with no indications of isolation by distance in the samples. This conclusion is reinforced by analyses of molecular variance (AMOVA) and the population statistic Fst. Neutrality tests and mismatch distribution for mtDNA COI and ND1 sequences reveal strong evidence of population expansion and in combination with the lack of phylogeographical structure, it may reflect a recent range expansion.
