This is the poster I presented at the Midwest Ecology and Evolution Conference (MEEC) back in March. I analyzed the data Lee Rodman collected in her experiments last summer and added my own observations of Helianthus pauciflorus. Style Persistence appears to be a good measure of pollen limitation in species other than Echinacea. This field season, I will test Style Persistence as a measure of pollen limitation in Helianthus species.
