Trees to treehoppers: genetic variation in host plants contributes to variation in the mating signals of a plant-feeding insect.

Abstract excerpt

Community genetics research has demonstrated 'bottom-up' effects of genetic variation within a plant species in shaping the larger community with which it interacts, such as compositions of arthropod faunas. We demonstrate that such cross-trophic interactions also influence sexually selected traits. We used a member of the Enchenopa binotata species complex of treehoppers (Hemiptera: Membracidae) to ask whether...
