About the Society Awards Past Award Winners 2011 Awardees 2011 (Patterson Memorial Grant) Cory Redman

The goal of the study to quantitatively characterize changes in the community structure of terrestrial ecosystems before and after the Cretaceous-Paleocene (K-P) mass extinction event, using whole assemblage, rank abundance curves of vertebrates and pollen.  The rationale for conducting this study is to determine if latest
Maastrichtian terrestrial communities were already on the verge of collapse prior to the K-P boundary, by directly analyzing pre- and post- extinction ecosystems using different trophic levels (i.e., vertebrates = primary & secondary consumers; pollen= primary producers).
