Figure 1.

A distribution map of Daphnia galeata, D. dentifera, and D. Longispina. Red-filled regions represent the distribution of Daphnia galeata [12]. The blue and black lines indicate the distributions of D. dentifera and D. longispina sensu Petrusek et al. [50]. A dotted line represents the putative boundaries of the distributions based on a recent phylogeographic study [21].
