Join professor Lew Feldman to learn the botany behind the celebrated plant changes associated with the fall season. We'll explore why (and how) some leaves appear to change color--exhibiting reds, yellows, and oranges--and the environmental influences that affect the brilliance of those colors. In addition, Dr. Feldman will explain the evolutionary benefits and processes for a tree to lose its leaves (deciduousness), the occurrence that gives this season its name.
