Fig. 3From: The evolution of reproductive isolation in DaphniaThe independent contributions of reproductive isolation barriers (RIi) between Daphnia pulex and Daphnia pulicaria. a total mean reproductive barrier is shown in red, sympatric in green and allopatric populations in blue, b accounting for asymmetry of reproductive barriers for reciprocal crosses, reproductive barriers for D. pulicaria female crossed with D. pulex male in red, and D. pulex female crossed with D. pulicaria male in blue, c reproductive barriers accounting for asymmetry for sympatric populations, were sympatric D. pulicaria x D. pulex is in red and sympatric D. pulex x D. pulicaria in blue, d accounting for asymmetry for allopatric populations, where allopatric D. pulicaria x D. pulex is in red and allopatric D. pulex x D. pulicaria in blue. The reproductive barriers among conspecific populations of D. pulex (e) and D. pulicaria (f), where barrier strength of is shown for mean (red), geographically close (green) and geographically far (blue) crosses.
