Figure 7 in Species diversity and endemism in the Daphnia of Argentina: a genetic investigation

Figure 7. NJ tree based on COI sequence variation among all unique haplotypes of Argentine populations belonging to the subgenus Ctenodaphnia. Two members of the subgenus Daphnia (D. obtusa and D. pulex) were included to root the tree. Bootstrap values are presented for major clusters, and K2P distances are indicated by the scale bar. The collection site of each individual is indicated by its population code (see Appendix 1). Individuals morphologically identified as D. notacantha are indicated by an asterisk. This tree is not intended to represent a phylogenetic hypothesis for the subgenus.
