Title: Extinction: Past, Present and Future

Abstract: The defining feature of a mass extinction is the global amount of extinction that occurred. However, there is finer-scale detail to the story, as seen in the ongoing modern mass extinction (the 6th mass extinction), which exhibits variable effects among ecosystems and environments, and hence geographic areas. One way to better understand this biological and spatial variability is to examine ancient mass extinctions, particularly those with the largest amount of extinction (the Big 5 mass extinctions), where nature has already run the experiment.

Bio: Professor Bottjer is a paleobiologist and paleoecologist who has worked broadly on organism-sediment interactions and the ecological history of life. His current research focuses on two broad paleobiological questions. The first includes a multidisciplinary approach to understanding the paleobiology and paleoecology of early metazoan life, with field work conducted in eastern California and China. The second emphasizes obtaining a detailed understanding of the paleoecology of the recovery from the end-Permian and end-Triassic mass extinctions, with extensive work on Triassic strata throughout the western U.S., Europe, Japan and China. This Triassic research project has led to involvement in the Paleobiology Database, which has undertaken the development of large databases with web-based access to solve major outstanding paleobiological and evolutionary problems.
