Larval Performance in the Context of Ecological Diversification and Speciation in Lycaeides Butterflies
Figure 2
Survival and emergence weights from rearing experiments: (a and b) L. idas, (c and d) hybrid species, (e and f) L. melissa. Values are standardized ( transformed). Shading of bars indicates plant species; see legends and Figure 1 for population locations. See Table 2 for associated model details, including plant and population effects. Significant differences () for population effects within plants are indicated here with small letters near bars. Black dots identify natal host associations for each population. Host plant abbreviations as follows. Ac; Astragalus canadensis; Aw; Astragalus whitneyi; Ln; Lotus nevadensis; Lp; Lupinus polyphyllus. Results from alfalfa, M. sativa, are not shown here because survival was very low; see main text for details.
