“Recovery of Plant-Insect Associations in the Wake of the Dinosaur Extinction”
The Chicxulub asteroid impact in Mexico during the Cretaceous/Palaeogene resulted in mass extinctions, bringing the golden age of dinosaurs to an abrupt end. But what was happening to all the other life forms on earth during this time? Dr. Donovan will discuss his work examining insect-feeding damage on thousands of fossil leaves from one of the most important fossil sites in in the world, Chubut, Patagonia, Argentina, located far south of the Chicxulub impact crater. Overall, this works demonstrates a rapid recovery of insect herbivores and their food webs, supporting the emerging idea of large-scale geographic differences in extinction and recovery from the end-Cretaceous catastrophe.
This lecture is being presented as part of the Bio-alliance, a collaboration between Holden Forests & Gardens, Case Western Reserve University, the Cleveland Museum of Natural History and the Cleveland Metroparks Zoo. The Bio-alliance was formed in April 2019 to promote local opportunities and resources, to create transformative educational experiences, and to inspire inter-institutional research in biodiversity, ecology and evolutionary biology across the premier biological research institutes of Northeast Ohio.
