The Ghosts of Populations Past

What Old Shells Reveal about Current and Future Oceans, Dr. Paul Harnik, Ph,D, Franklin and Marshall  7-8 pm.  Free and open to the public.  Lecture is followed by light refreshments and conversation with the speaker.

How have human activities altered coastal ecosystems in the Gulf of Mexico? Answering this question is challenging because humans have been interacting with coastal ecosystems for millennia, yet scientific monitoring of these environments is typically limited to a few decades at the most. In this talk, I will discuss how the skeletal remains of organisms can be used to establish baselines for ecosystems prior to human-caused environmental change. Comparing these baselines with the characteristics of present-day populations can reveal historical changes and inform our predictions for how coastal species will respond to projected environmental conditions. I will present examples from my research across the Northern Gulf that illustrate the ways in which mollusks have responded to anthropogenic eutrophication.
