Lakes hold a hidden history beneath their surfaces, preserved in layers of sediment that accumulate over time. In this lecture, Dr. Trisha Spanbauer will explore how interdisciplinary research is uncovering the ecological and evolutionary changes that have shaped aquatic ecosystems. By analyzing fossil and DNA records from ancient lakes in South America and Africa, as well as younger lakes in the Midwest and Rocky Mountains, Dr. Spanbauer and her team reveal how environmental disturbances have influenced lake ecosystems over time.

This lecture is free, but registration is required. Donations are always happily accepted.

Dr. Trisha Spanbauer joined the Department of Environmental Sciences at the University of Toledo in 2019, and she is currently a resident faculty member at the Lake Erie Center. Prior to becoming a professor, Dr. Spanbauer received a BFA in Visual Art and Art History from the University of Wisconsin-Milwaukee and a Ph.D. in Geology and Biology from the University of Nebraska-Lincoln. Research in her lab is broadly interested in ecological and evolutionary change over a broad range of timescales, with a specialization in using fossils and genetic material from sediment archives to understand global environmental change.
