Is rarity linked to extinction in the fossil record? Synthesizing data from background and mass extinctions in U.S. Coastal Plain mollusks

Principal Investigators:

Rowan Lockwood

Ecological studies suggest that rare taxa are more likely to go extinct than abundant ones, but the relationship between rarity and extinction in the fossil record has received surprisingly little attention. The purpose of this research is to examine the link between rarity (defined here to include mean abundance, spatial and temporal variability in abundance, geographic range, and habitat specificity) and extinction during both background and mass extinction intervals in the Cenozoic record of U.S. Coastal Plain mollusks. The questions I will address... more
