Figure 2

Phylogenetic network of 53 partial Pokey sequences from isolates of the Daphnia pulex complex. The network was constructed using the NeighborNet algorithm. Dashed lines delineate sequence groups presented in Table 2. Colors represent species or hybrid state of isolates: red = D. pulex, light blue = D. arenata, grey = D. tenebrosa, black = European D. pulex, dark blue = European D. pulicaria, green = D. pulicaria, orange = putative pulex-pulicaria hybrids, purple = the isolate with D. tenebrosa mtDNA and a D. pulex nuclear genome.
