Testing the effect of DNA sequence length. Legend: We compared results from 300 bp, 600 bp, 1200 bp and 2400 bp with those estimated from the true tree. The left pane shows the effect of nucleotide sampling on the threshold parameter (number of species). The dots are posterior means of individual replicates. The blue line indicates the number of expected species (50) and the red line shows the mean number of species diverging earlier than 4 N generations. The right pane shows the 95% HPD interval for each replicate. Gray points indicate the HPD overlapped the true number of species, black ones that it did not.
