Invasion by hybridization between native and non-native purple coneflowers

Year: 2013
Project Description:

In western Minnesota prairie restorations have been planted near native prairie remnants. Two non-native Echinacea species (E. pallida and E. purpurea) have been planted in restorations. We want to know the extent to which the non-natives affect reproduction in the native species. Non-native pollen is hypothesized to interfere with pollination in the native and hybridization between the species may occur. For this project, you will design an experiment, in collaboration with the mentor, to investigate potential interactions between 2-3 species of Echinacea. Crossing and pollen addition experiments will occur in experimental plots, restorations, and prairies in our study site in western Minnesota.
