Ultrametric time-calibrated phylogenetic tree obtained with BEAST for nd5 data in Carabus. Nodes J1, J2, J3, J4b, M2, M3, C and F (labeled green) were used as calibration points (detailed information on node age priors as shown in Table 2). The HPD distribution of ages obtained for nodes A, B and C (labeled red) are used as priors for subsequent calibration analyses on the different individual and combined datasets.
