Pair-wise genetic differentiation (Φ_ST) between species calculated via AMOVA using 997 bp of mitochondrial D-loop data. Flying ducks from the Falkland Islands (FLK) are not significantly (n.s.) differentiated from Falkland steamer ducks (Φ_ST = 0.01706, p = 0.29) based on the short historic fragment (337 bp) and were not compared with the continental populations.
