Figure 5 in Species diversity and endemism in the Daphnia of Argentina: a genetic investigation

Figure 5. NJ tree based on COI sequence variation among Argentine populations identified as D. laevis and D. gessneri. The identifications, based on head morphology, are indicated in this tree, followed by the collection site numbers. Sequences from the North American members of the D. laevis complex (D. dubia, D. laevis, and D. magniceps) were included for comparison. D. mendotae, a Hyalodaphnia species belonging to a different species complex (Colbourne & Hebert, 1996), was used to root the tree. The scale bar represents K2P distance.
