h - haplotype diversity, π - nucleotide diversity (= mean pairwise distance, observed; standard errors based on bootstrapping), mean pairwise GTR distance. UPGMA basal distances with corresponding TMRCA ages (Time to Most Recent Common Ancestor), based on the operational u=0.75 My^-1 lineage^-1 site^-1 rate.
