Congratulations to CEB student Jonathan Mitchell for his recent article in the Proceedings of the National Academy of Sciences!

In their paper, Jonathan and his co-authors Peter Roopnarine of the California Academy of Sciences and Kenneth Angielczyk of the Field Museum (and CEB faculty member), used food web models to show that fragile ecosystems may have exacerbated the impact and severity of the end-Cretaceous extinction in North America.
