南极章鱼Pareledone turqueti的样本取自南大洋斯科舍海岭的三个地点。用同工酶电泳分析了这些群体的遗传同质性。虽然panmixia似乎是保持在南格鲁吉亚（F-ST = 0）之间的基因流这个岛和沙格岩，一个岛屿只有150公里远，但分开了很大的深度，是非常有限的（F-ST = 0.74）。这些结果进行了检查的不连续分布的P. turqueti在整个南极洲。还计算了有效群体大小的估计值（N-e = 3600）。
Samples 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).
