Larval Performance in the Context of Ecological Diversification and Speciation in Lycaeides Butterflies

Figure 4

Summary of hypotheses relating ecological traits to reproductive isolation between taxa based on the current and past studies [16, 17, 19, 22, 23]. Arrows joining two taxa correspond to greater gene flow and those that are faded represent gene flow that could be prevented or reduced by a given trait. For details see text.
