“Messy Rivers are Healthy Rivers”

Perceptions of river health are influenced by expectations regarding the appearance of a natural river, but appearance depends on geomorphic context and river history. I examine how physical complexity – messiness – influences river health, how human activities simplify rivers and compromise river health, and how we can restore complexity and ecosystem services provided by rivers.

“John Muir and the Religion of Nature: A Bankrupt Legacy?"

John Muir and the cause for which he fought, the preservation of wild nature, have been assaulted as tainted by racism, indifferent to the most pressing environmental problems, and bankrupt intellectually and morally. It is time for a new and more fair-minded appraisal of both the man and his cause.

Professor Worster has held fellowships from the Guggenheim Foundation, the Australian National University, the National Endowment for the Humanities, the Mellon Foundation, and the American Council of Learned Societies. He has written eight books, which together have won more than dozen book prizes. He is former president of the American Society for Environmental History and a member of the American Academy of Arts and Sciences.

“Adventures in a Natural History Museum.”

Henry David Thoreau went to the woods to study nature. Laurel Ulrich and her students went to a Natural History Museum to study Thoreau. There they not only discovered Thoreau’s pond turtle, but a fish that taught them to write, and new vantage point on botany by considering a 116-year-old tortilla. These are only a few of the tangible things Professor Ulrich will explore in her lecture.

Ulrich has written six books, including Well-Behaved Women Seldom Make History and A Midwife's Tale, which was later developed into a documentary film for the PBS series American Experience. Ulrich has won the Pulitzer Prize, the Bancroft Prize, and she’s received a MacArthur “Genius Award” Fellowship, among other numerous prizes and distinctions.
