Figure 2. Maximum likelihood tree using nuclear genome
sequences. South Island, NZ Daphnia samples (red circles); North
Island, NZ Daphnia sample (red ring); D. pulex samples
(black circles); D. pulicaria samples are marked with blue
circles. Inset on the right shows the phylogeny of the South
Island and North American D. pulicaria in more detail. Bootstrap
>75 are shown. T1 is the divergent time
between the North American and the South Island D. pulicaria.T2 is the expansion time of South Island D.
pulicaria .
