Fig. 2From: Comparative phylogeography of endemic Azorean arthropodsBEAST maximum clade credibility tree (concatenated 3 mtDNA genes dataset) of Gibarranea occidentalis showing the median age estimates of all the splitting events. Numbers on branches are the posterior probability values of the BEAST inference (only values above 0.5 are shown). The nodes of major splitting events are marked with coloured letters. The inset table presents the probability (state probability) of each colour-coded island (according to the legend) being the ancestral area of the respective letter-coded node. The median age corresponding to each letter-coded node is indicated in the table and the numbers within brackets are the 95Â % HPD intervals. The scale bar and the time axis are in Ma. Tip names are colour-coded by location (island) of origin. The inset map depicts the current geographical setting of the Azores, black lines indicate strongly supported colonization eventsBack to article page
