  1. AMOVA based on allelic frequencies variation with significance calculated by 10,000 permutations of the original dataset.
  2. (*) Geographical groups: one group with samples from Southern Ocean Atlantic Sector (SG-1994, SG-1997, EI-2007, SS-2007, W-1992, B-1992, P-1997) and the other with samples from the Southern Ocean Pacific Sector (five temporal replicates from Ross Sea. R-1994, R-1995, R-1996, R-1997, R-1999).
