Undersampling Taxa Will Underestimate Molecular Divergence Dates: An Example from the South American Lizard Clade Liolaemini
Figure 1
Phylogenetic relationships and timetree for taxa within the iguanid lizard clade Liolaemini. A single ML topology () was obtained from analysis of 1599 aligned base positions of ND1-COI data (1283 distinct site patterns) using the best-fit partitioning scheme found with PartitionFinder and GTR+Ī+I for all partitions. Asterisks above branches denote bootstrap values between 95 and 100%, dashes above branches denote bootstrap values between 94 and 70%, and branches without notation have bootstrap values below 70%. This timetree represents the point estimate of node divergences among Liolaemini taxa and does not include mean and standard deviation values from bootstrapped trees (see Tables 1ā5). Branches labeled with circled numbers represent the following major clades: (1) L. nigromaculatus group, (2) L. lemniscatus group, (3) L. elongatus-L. kriegii complexes, (4) L. bibronii-L. alticolor groups, (5) L. chiliensis group, (6) L. lineomaculatus section, (7) L. montanus series, (8) L. wiegmannii series, (9) L. melanops group, and (10) L. darwinii complex.
