Ancestral character state reconstruction for the locality of the bottlebrush octocorals through a stochastic mapping approach. This analysis was run under a symmetric rate model, an empirical Q matrix, and 1000 simulations using the packages ‘phytools’ [107] and ‘geiger’ [108] in R. The figure shows an example of nine reconstructions from a simulation of 1000 trees, where is evident the lack of resolution on the ancestral locality for node A, B, and C. The colours correspond to the localities: red for Tasmania, green for New Zealand, orange for Macquarie Ridge, and blue for Antarctica. (DOCX 319 kb)
