Seminar Title: The Recovery of Life After the End Cretaceous Mass Extinction

Abstract: Without substantial changes in anthropogenic pressures, the current biodiversity crisis could very well rise to the level of a major mass extinction of the magnitude of the so-called "Big Five" mass extinctions of Earth history. These ancient events provide crucial insights into how ecosystems collapse and how they recover afterward; the most recent, the End Cretaceous mass extinction, is perhaps the only major event in the history of life which happened faster than modern climate change. This talk focuses on the recovery of life following the end Cretaceous mass extinction at a variety of scales, from the rapid return to a habitable environment (years to decades after the extinction), to the recovery of marine ecosystem function (within a few million years of the extinction), to finally the recovery of biodiversity (10 myr after the extinction). The timing of these different milestones of the overall recovery of life highlights the fact that humans have the potential to cause changes to the biosphere on geologic timescales and highlights the urgent need for conservation.
