We've heard that people sometimes self-medicate, but did you know that Monarch butterflies do also? Join Mark Hunter, Henry A. Gleason Collegiate Professor of Ecology and Evolutionary Biology, and graduate student Leslie Decker as we discuss the imperiled migratory Monarch population, and the complex relationships among butterflies, host plants, parasites and predators. How might climate change affect these interactions? What can local individuals and organizations do to help these fragile populations?
