Restricted gene flow and evolutionary divergence between geographically separated populations of the Antarctic octopus Pareledone turqueti

first_imgSamples of the Antarctic octopus Pareledone turqueti were taken from three locations on the Scotia Ridge in the Southern Ocean. The genetic homogeneity of these populations was investigated using isozyme electrophoresis. Whilst panmixia appeared to be maintained around South Georgia (F-ST = 0) gene flow between this island and Shag Rocks, an island only 150 km away but separated by great depths, was extremely limited (F-ST = 0.74). These results are examined with respect to the discontinuous distribution of P. turqueti throughout Antarctica. An estimate of effective population size was also calculated (N-e = 3600).last_img

We tried to play, we did well in the first half but didn’t have a lot of chances in the final third. We need to keep calmer in the final third and find the final ball, but in the second half we didn’t start well and conceded early. “After that we tried to push for the rest of the game, we had some chances and we didn’t score so it is difficult to come back with no points but we need two continue to fight to make the top four.”We are all together, it is not down to] one or two players, we are a group and we need to stay together and to push more for the next game.” last_img read more
