Autumn Colors: A Mystery Revealed October 25, 2011

Speaker: David Lee, Tropical Botanist, Florida International University

Part of the magic of living in New England is the stunning display of autumn foliage. But how, exactly, does the shift from greens to crimsons, yellows, burgundies, and oranges take place? And why are we treated to such a display? David Lee, who has spent his career studying the intricacies of color in plants, will explain some of the chemical processes, cellular communications, and fluid dynamics that take place within a deciduous plant come fall and also the signals to humans and animals that are communicated through plant pigments.
