Figure 3.

DNA barcodes of COI and similarly sized sequences from cytb demonstrate three distinct geographically and genetically distinct groups within the neotropical bat species Sturnira lilum. Individual variation between cytochrome b sequences is greater than those within barcode sequences but resolution is internally consistent. The trees are assembled by using K2P genetic distances [20] in a neighbor-joining method [13]. Bootstrap values (1000 replicates) for major geographic lineages are shown above each branch.
