Thursday, November 18, 6:00 pm – Thoreau as a Climatologist

Henry David Thoreau initiated a study of flowering times at Walden Pond. Today, a research team including Charles Davis, Assistant Professor of Organismic and Evolutionary Biology at Harvard University, has updated Thoreau’s records with current data and integrated them with modern evolutionary biology to reveal how climate change and earlier flowering times have affected Walden’s plants.

Join Davis to explore an integrated approach to climate change and biodiversity on Thursday, November 18, beginning at 6 pm at the Harvard Museum of Natural History, 24 Oxford Street in Cambridge. Part of the Asa Gray Bicentennial series, this event is free and open to the public.For more information, log on to, or call 617-495-3045.
