Winter Lyceum (4 of 7): Dr. Jack Williams Presents “Changes in Wisconsin Ecosystems and Environments Since the Last Ice Age”
March 13, 2022 @ 5:00 pm – 6:00 pm
UW-Madison geography professor Dr. Jack Williams paints a picture of the ecological upheaval of the North American landscape just after the retreat of the ice sheets 15,000 years ago. Recent research using fossil pollen, charcoal and dung fungus spores help us visualize a post-ice age terrain different from anything in the world today. The disappearance of mammoths, giant beavers, ground sloths and other large animals preceded a massive change in plant communities, providing new insight into the dynamics of extinction and its pervasive influence on a given landscape.
Each year, the museum invites a series of speakers to share their unique stories, histories, and insights. The 2022 Winter Lyceum will run each Sunday from February 20 to April 3, and will feature seven engaging hour-long lectures for the price of $4 each or $20 for all seven. The lectures will be held online via Zoom, and a link will be provided upon registration.
