Fig. 5From: The Antarctic Circumpolar Current as a diversification trigger for deep-sea octocoralsGraphical summary of relative unidirectional migration rates estimated from the best-supported model of population structure. The arrows show the estimates for the direction of migration between populations of the primnoid bottlebrush octocorals from the South Pacific and Southern Ocean, and the thicknesses are proportional to the mutation-scaled migration rate (M). Populations are labelled as follows: T for Tasmania, MQ for Macquarie Ridge, NZ for New Zealand, and A for AntarcticaBack to article page
