The Physical Fitness of Leaves May 30, 2013

Every organism must contend with its immediate physical environment, a world that both limits what organisms can do and offers innumerable opportunities for evolving ways to challenge those limits. Steven Vogel, author of The Life of a Leaf, will explain these interactions, using the leaf as example. He’ll answer questions about how objects get much hotter than air when in sunlight and far cooler when beneath a clear night sky; how air movement matters even when we can’t feel it; how objects such as trees avoid damage from storms; and ways leaves acquire the essential resources for growth and reproduction. Join us to learn about some of the extraordinary designs that enable a leaf to adapt to its physical world.
